Grundsicherung im Alter und bei Erwerbsminderung

Grundsicherung im Alter und bei Erwerbsminderung (basic security in old age and on reduced earning capacity, often shortened in administrative use to GruSi or Grundsicherung-Alter) is Germany's needs-based minimum-income guarantee for elderly people and for adults of working age who are permanently unable to earn a living because of disability or chronic illness. Its statutory basis is the Zwölftes Buch Sozialgesetzbuch (Sozialgesetzbuch XII — SGB XII), specifically the dedicated Viertes Kapitel covering §§ 41 to 46a SGB XII. The benefit was introduced in 2003 as a standalone scheme to remove the stigma and the family-recourse mechanics of classical Sozialhilfe (social assistance) for two specific population groups whose poverty is by definition structural and not the outcome of short-term life shocks: people who have aged past the standard retirement threshold (Regelaltersgrenze), and people of working age whose earning capacity has been fully and durably extinguished (volle Erwerbsminderung auf Dauer) within the meaning of § 43 Abs. 2 SGB VI.

The legislative purpose stated in § 41 Abs. 1 SGB XII is to secure the notwendigen Lebensunterhalt (the necessary cost of living) for people who can no longer be reasonably expected to support themselves through work. The benefit is therefore unambiguously a Fursorgeleistung (welfare benefit) in the technical German distinction between Versicherungsleistungen (contribution-based insurance benefits like Rente) and Versorgungsleistungen (provision benefits like Beamtenpensionen) on one side and tax-financed Fursorge on the other. It is paid from the federal budget, with administration delegated to the local Sozialamt (municipal social welfare office) of the applicant's habitual residence, in line with §§ 97-99 SGB XII. Since the 2014 federalisation reform, the federal government carries 100% of the net spending on Grundsicherung im Alter, lifting an earlier funding burden off the Kommunen (municipalities).

Two structural design choices distinguish Grundsicherung im Alter from the more general Sozialhilfe of the Drittes Kapitel SGB XII (Hilfe zum Lebensunterhalt). First, the benefit is paid for a renewable Bewilligungszeitraum (grant period) of normally twelve months in advance (§ 44 Abs. 1 SGB XII), rather than month-by-month, giving recipients budgetary stability. Second, and most importantly for elderly applicants, there is no Unterhaltsruckgriff (recovery from family members) against children whose yearly gross income falls below €100,000, since the Angehorigen-Entlastungsgesetz took effect on 1 January 2020. Before that reform, adult children whose income exceeded relatively modest thresholds were routinely pulled into pay obligations toward an elderly parent on Grundsicherung — a deterrent so powerful that the Bundesregierung's own 2018 evaluation estimated verdeckte Altersarmut (hidden old-age poverty) at roughly 60% of the eligible population, i.e. three out of five qualified pensioners refused to file because they feared causing their children financial harm or shame. The 2020 reform addressed this directly.

The benefit's underlying constitutional anchor is Article 1 Abs. 1 GG (human dignity) in conjunction with the social-state principle of Article 20 Abs. 1 GG. The Bundesverfassungsgericht's 2010 Hartz-IV ruling (1 BvL 1/09) and its 2014 follow-up (1 BvL 10/12) defined a constitutionally guaranteed Existenzminimum — a sociocultural minimum subsistence floor — that the legislator must secure through transparent and evidence-based calculations. The annual Regelbedarfsermittlung (regular needs determination, currently §§ 28-28a SGB XII in conjunction with the Regelbedarfs-Ermittlungsgesetz) implements this constitutional duty, and the Regelsatze (standard rates) are uprated each January by a statutory mixed index of price and wage inflation under § 28a SGB XII.

Eligibility for Grundsicherung im Alter und bei Erwerbsminderung rests on a combined personal, residence, income and asset test. All four prongs must be met simultaneously for the Sozialamt to grant the benefit.

1. Personal eligibility (§ 41 Abs. 2 SGB XII). Two alternative gateways exist. The first is age: the applicant must have reached the Regelaltersgrenze of the statutory pension insurance. For the cohort born in 1947 this was 65 years exactly; for each subsequent birth-year cohort the threshold rises stepwise toward 67. People born in 1964 or later reach the threshold at 67 years; in 2025 the typical applicant has thus been born no later than 1958 and has reached 66 years and 2 months. The second gateway is full and durable reduced earning capacity (volle Erwerbsminderung auf Dauer): the applicant is at least 18 years old, has not yet reached the Regelaltersgrenze, and has been medically certified by the Deutsche Rentenversicherung (or its medical service) as being unable to work more than three hours per day on the general labour market for reasons of physical, mental or psychological impairment, with the impairment expected to persist for at least three years or to be permanent.

2. Residence. The applicant must have habitual residence (gewohnlicher Aufenthalt) in Germany under § 30 SGB I. Tourists, short-term visitors and people whose residence permit expressly excludes welfare benefits are not eligible. EU citizens are covered on the same terms as Germans where they have worker status or have completed five years of legal residence (Daueraufenthaltsrecht under § 4a FreizugG/EU). Non-EU citizens need a settlement permit (Niederlassungserlaubnis) or a permanent EU residence permit (Erlaubnis zum Daueraufenthalt-EU); applicants on short-term residence titles are usually excluded by § 23 Abs. 3 SGB XII, although recognised refugees and beneficiaries of subsidiary protection have full access.

3. Income test (§§ 82-84 SGB XII). All household income is assessed: gesetzliche Rente (statutory pension), Betriebsrente (occupational pension), Riester- and Rurup-Rente (private contractual pensions), capital income, alimony received, and any earnings. Income is taken net (after tax, social-insurance contributions, and certain allowable deductions such as work-related expenses Werbungskosten and Versicherungspauschale of €30/month). The Grundsicherung tops the income up to the household's notwendiger Lebensunterhalt — i.e. it pays the difference between the income figure and the calculated need. A modest Freibetrag on additional voluntary pension income exists under § 82a SGB XII (since the 2018 Rentenpaket): the first €100/month of contributory pension income is fully exempted, and 30% of the next €427 is also exempted, capping the total exemption at €224/month in 2025.

4. Asset test (§ 90 SGB XII in conjunction with § 1 of the Verordnung zur Durchfuhrung des § 90 SGB XII). Liquid and realisable assets above a fixed Schonbetrag (protected amount) disqualify the applicant. Since 1 January 2023 the protected amount is €10,000 for a single adult, €20,000 for a couple (i.e. €10,000 per spouse, not €15,000 combined as in some other welfare contexts; this is one of the asymmetries between SGB XII and SGB II), and an additional €500 for each further dependent person in the household. Schonvermogen not counted toward the limit includes: a self-occupied home of appropriate size, household effects, a motor vehicle of appropriate value, and items of religious, sentimental or cultural value. A small life-insurance contract with a guaranteed surrender value below the Schonbetrag is also protected. Larger life insurances, securities accounts, savings books, and any second home are fully assessed and must be liquidated above the Schonbetrag.

5. The Angehorigen-Entlastung (family relief). A defining feature of Grundsicherung im Alter since 1 January 2020 is that adult children are not drawn into Unterhaltsruckgriff unless their individual annual gross income exceeds €100,000 (§ 94 Abs. 1a SGB XII). Below that ceiling, the Sozialamt does not even contact the children to inquire about their income; the protective threshold is presumed satisfied. This single reform removed the largest psychological barrier to take-up for elderly parents whose grown-up children earn modest middle-class incomes.

The benefit amount under §§ 41-43 SGB XII has three building blocks: the Regelsatz (standard rate covering everyday subsistence), the Mehrbedarfe (additional needs surcharges for specific life situations), and the Kosten der Unterkunft und Heizung (KdU — actual housing and heating costs). The three together yield the household's notwendiger Lebensunterhalt; the Sozialamt pays the difference between this figure and the household's countable net income.

Regelsatz 2025 (§ 28 SGB XII in conjunction with the Regelbedarfsstufen). Standard rates per month, valid from 1 January 2025:

• Regelbedarfsstufe 1 — single adult or single parent: €563
• Regelbedarfsstufe 2 — adults in a partner household: €506 per partner
• Regelbedarfsstufe 3 — adult dependant in someone else's household, e.g. an adult son living with parents: €451
• Regelbedarfsstufe 4 — children aged 14-17: €471
• Regelbedarfsstufe 5 — children aged 6-13: €390
• Regelbedarfsstufe 6 — children 0-5: €357

The 2025 rates reflect the major statutory uprating of January 2023 (Burgergeld-Gesetz) and the index-based January 2024 and January 2025 adjustments under § 28a SGB XII. The Regelsatz is intended to cover food, clothing, household goods, personal hygiene, transport, household electricity, social and cultural participation, and a small reserve for one-off items.

Mehrbedarfe (§ 30 SGB XII). Specific surcharges added on top of the Regelsatz:

• Mehrbedarf für werdende Mütter (pregnancy, from week 13): 17% of the Regelsatz, i.e. €96/month in 2025.
• Mehrbedarf für Alleinerziehende (single parents with at least one child under 7 or with two/three children under 16): graded 12-60% of the Regelsatz, i.e. €68-338/month.
• Mehrbedarf für behinderte Menschen with severe disability mark G (gehbehindert) when receiving an Eingliederungshilfe Werkstatt place: 35% of the Regelsatz, i.e. €197/month.
• Mehrbedarf für kostenaufwändige Ernährung (medically prescribed special diet for certain chronic diseases — e.g. coeliac disease, severe diabetes, end-stage renal disease): typically €25-90/month depending on diagnosis.
• Mehrbedarf für dezentrale Warmwasserbereitung (decentralised hot-water heating, i.e. an electric boiler that runs off household electricity): 2.3% of the Regelsatz for an adult Regelbedarfsstufe 1, i.e. €13/month.

Kosten der Unterkunft und Heizung (KdU, § 35 SGB XII). Actual rent and actual heating costs are reimbursed in full, provided they are angemessen (appropriate) for the household size and the local rental market. Each Sozialamt publishes a schlüssiges Konzept (coherent concept) under jurisprudence of the Bundessozialgericht that defines local appropriateness thresholds — typically the median net cold rent for a flat of the prescribed size in the lower third of the local market. For a single adult in a mid-sized German city the typical appropriate cold rent (Nettokaltmiete) is €380-520/month plus Betriebskosten (operating costs) of €70-110/month plus Heizkosten (heating) of €60-130/month. In Munich, Frankfurt, Hamburg and Stuttgart the appropriate cold-rent ceiling for one person rises to €650-820/month. Where actual rent exceeds the local ceiling the Sozialamt grants the excess for up to six months while the recipient is expected to look for cheaper accommodation; after six months only the ceiling is paid and the recipient bears the excess.

Worked example. A single 70-year-old widow in Leipzig, Saxony, with a statutory pension of €920 net per month and no other income, rents a 50 m² flat for €380 net cold + €90 Betriebskosten + €80 heating = €550/month. Her need: €563 Regelsatz + €550 KdU = €1,113/month. Less her income of €920 plus the §-82a-pension-freibetrag of €100 = €1,020 countable. Grundsicherung tops up €1,113 − €920 + €100 freibetrag credit = a net Grundsicherung payment of €193/month. She also receives a GEZ-Befreiung (broadcasting-fee exemption) and reduced public-transport fares.

One-off needs (§ 31 SGB XII). The Sozialamt grants one-off lump sums for the first set-up of a household (Erstausstattung Wohnung), the first set-up after pregnancy (Erstausstattung Schwangerschaft), and for orthopaedic shoes and corrective devices not covered by health insurance. Typical one-off payments range from €350 (bed and bedding) to €1,500 (full kitchen set-up).

Applications for Grundsicherung im Alter und bei Erwerbsminderung are filed with the Sozialamt of the municipality (Gemeinde, Stadt or kreisangehörige Verwaltungsgemeinschaft) in which the applicant has habitual residence. In larger cities the Sozialamt is integrated into the Sozialburgeramt or the Amt für Soziales und Wohnen of the municipal administration; in rural districts it sits with the Kreisverwaltung. There is no central federal counter — every application is local, even though the federal budget covers the full net cost.

Paper application. The traditional route is the paper antrag (form). The federal Ministry of Labour and Social Affairs (BMAS) provides a model form that each Bundesland adapts. The form has 12-18 pages and asks for personal data, household composition, all income sources, all assets, the rental contract, and pension data. Supporting documents must be attached. Most municipalities also offer a vereinfachter Antrag (simplified form) for renewals, which only asks for changes since the last grant period.

Online application. Since the OZG (Onlinezugangsgesetz) digitalisation push in 2022, most large municipalities offer a digital antrag. Examples: Berlin (service.berlin.de), Hamburg (gateway.hamburg.de), Munich (muenchen.de Burgerservices), Cologne, Frankfurt am Main, Stuttgart, Düsseldorf and Leipzig all accept online filing with the BundID or a Burger-Konto. The online flow guides the applicant through the same fields as the paper form and lets the user upload PDF/photo attachments. Some smaller Sozialämter still require paper — check the municipality's website before filing.

Required documents. Standard set:

• Personalausweis or Reisepass (identity document), and for non-EU citizens the residence permit
• Rentenbescheid (pension decision letter) from the Deutsche Rentenversicherung and from any occupational or private pension provider, showing the current gross and net amounts
• If applying under volle Erwerbsminderung: the medical Gutachten or the DRV Erwerbsminderungs-Bescheid certifying full and durable reduced earning capacity
• Rental contract (Mietvertrag), the three most recent rent payment receipts or bank statements, and the most recent Nebenkostenabrechnung (operating-cost statement)
• Heating-cost statement (Heizkostenabrechnung) for the last full heating period
• Bank statements (Kontoauszüge) for the last three months from every account in the applicant's name
• Savings-book entries or securities-account statements showing all assets
• Health-insurance card (Versichertenkarte)
• If receiving Pflegegrad benefits: the most recent Pflegegrad-Bescheid from the Pflegekasse
• Marriage certificate or partnership registration if applicable

Processing time and decision. The Sozialamt issues a Bescheid (formal decision letter) within typically four to eight weeks of receiving complete documents. Where documents are missing the Sozialamt sends a written request and the four-week clock pauses. In urgent cases — applicant has no income at all and no reserves — the Sozialamt grants a Vorschuss (advance payment) within five working days of the first interview, to bridge until the full decision. Backdated benefit runs from the first of the month in which the application was filed (§ 44 Abs. 1 SGB XII); applications filed on 2 March pay from 1 March, applications filed on 31 March still pay from 1 March, so it pays to file early in the month.

Payment. Benefit is paid into the recipient's bank account once per month on or shortly before the first calendar day of the benefit month. The first payment after a successful application includes any back-payment to the application date.

Appeals (§§ 77-86a SGG). A Widerspruch (objection) against the Bescheid must be filed within one month of receipt with the Sozialamt that issued it. If the Sozialamt does not change its decision in response, the case proceeds automatically to the Sozialgericht (social court). Sozialgericht proceedings are free of court fees for plaintiffs and require no lawyer; specialised free legal counsel is available through the Sozialverband VdK, the Sozialverband Deutschland (SoVD), and many Caritas/Diakonie offices.

Help filing. For households who find the paperwork overwhelming, free filing assistance is available at every Caritas Sozialstation, the Diakonie Sozialberatung, the Arbeiterwohlfahrt (AWO), the German Tenant Association (Deutscher Mieterbund) for rent-related questions, and from the VdK and SoVD for their members. Buronia provides a step-by-step German-language and English-language filing walkthrough that prefills the Sozialamt forms based on a single set of questions, calculates the likely benefit amount, identifies the responsible Sozialamt by postcode, and produces a printable submission package — see the Grundsicherung-im-Alter assistant on Buronia for the current city-by-city flow.

Most EU member states operate a tax-financed, means-tested minimum-income guarantee for elderly people whose contributory pension is below subsistence. The German Grundsicherung im Alter belongs to this family of resource-tested old-age safety nets and sits in the middle of the European spectrum on generosity, on take-up, and on integration with the contributory pension system. A comparison with the four most directly comparable continental schemes illustrates both the convergences and the divergences.

Austria — Ausgleichszulage (§§ 292-299 ASVG). The Austrian Ausgleichszulage is paid through the pension-insurance institutions themselves, not through a separate Sozialamt. It is technically a top-up to the pension, calculated as the difference between the recipient's pension plus other income and the Ausgleichszulagenrichtsatz (€1,273.99/month for a single person, €2,010.85 for a couple in 2025). The conceptual difference from Grundsicherung im Alter is significant: in Austria the safety net is administered by the same institution that pays the contributory pension, the applicant only ever talks to the pension authority, and stigma is minimal. In Germany the safety net is a separate Sozialamt-administered welfare benefit. Austria has the higher take-up rate as a result.

Netherlands — AIO (Aanvullende Inkomensvoorziening Ouderen, in Participatiewet Article 47a-47e). The Dutch AIO supplements the universal AOW state pension (which is paid to every Dutch resident from age 67 regardless of contribution record) up to the social-minimum benchmark. AOW alone is €1,478 net for a single retiree (2024 fourth quarter). AIO is paid by the Sociale Verzekeringsbank (SVB) on the same payment slip as AOW — so applicants again deal with a single institution. Conceptually closer to the Austrian model than the German one.

France — ASPA (Allocation de solidarité aux personnes âgées, Art. L. 815-1 ff. CSS). ASPA is paid by the pension carrier (CARSAT for private-sector workers, MSA for agricultural workers) on top of the contributory pension. The 2025 ASPA monthly maximum is €1,034.28 for a single person, €1,605.73 for a couple, after a means test against all income except certain disability allowances. Take-up is estimated at 60-70% of the eligible population — comparable to Germany before the 2020 Angehörigen-Entlastungsgesetz, lower since.

Spain — Pensión no contributiva de jubilación, Art. 144 ff. LGSS, plus the autonomous-community Ayuda a Mayores de 65 schemes. Spain operates a two-layer system. The state-level pensión no contributiva is €517.90/month (2025) for a person aged 65 or over with no contributory pension and insufficient resources. Several autonomous communities add a top-up (Cataluña, País Vasco, Andalucía). Spanish coverage is lower than the German Grundsicherung im Alter both in benefit level and in administrative reach.

Italy — Assegno sociale (Art. 3 Law 335/1995). €538.69/month for 13 monthly instalments per year, means-tested, paid by INPS. Comparable in level to Spain. Italy reformed its scheme in 2022 to ease the income test, but the benefit remains below the Eurostat at-risk-of-poverty threshold for single adults in northern Italian cities.

Belgium — GRAPA (Garantie de revenus aux personnes âgées / Inkomensgarantie voor Ouderen). €1,651.65/month for a single person (2025), one of the most generous European elderly safety nets in absolute level, paid by the Federal Pension Service.

The pattern across the EU is clear. Where the safety net is administered by the pension authority itself (Austria, Netherlands, France, Belgium), take-up tends to be higher and stigma lower; where it is administered by a local welfare office (Germany, Spain, Italy), take-up is lower and a non-trivial share of the eligible population — Germany's verdeckte Altersarmut — never files. The German legislator's 2020 family-recourse reform addressed one of the two main barriers (fear of recovery against children) but the second barrier (Gang zum Sozialamt — the journey to the welfare office) remains, and is the main reason German take-up of Grundsicherung im Alter still trails Austrian and Dutch take-up despite materially similar benefit levels.

For EU-mobile elderly people, the practical consequence is meaningful: German Grundsicherung im Alter is open to EU citizens with five years of legal residence (or earlier with worker status of the spouse), and the benefit is exportable in the narrow technical sense that recipients who acquire habitual residence elsewhere in the EU lose German Grundsicherung but become entitled to the host country's equivalent.

Grundsicherung im Alter und bei Erwerbsminderung is rarely the only benefit a low-income elderly or disabled person draws. The German welfare system layers several other federal and Land-level supports on top, and Grundsicherung recipients should systematically check each.

Wohngeld (Wohngeldgesetz). The federal housing allowance is in principle aimed at low-income households whose income is too high for Grundsicherung but too low to cover market rents from own resources. There is a formal Vorrang-Nachrang rule (§ 7 WoGG): Grundsicherung recipients normally receive their housing costs as KdU under SGB XII and therefore do not also get Wohngeld for the same period. But the inverse — applying for Wohngeld first to check whether the household can avoid Sozialamt involvement entirely — is often the optimal first step. The 2023 Wohngeld-Plus reform tripled the average payment to €370/month, and many elderly people whose pension is only just above the Grundsicherung threshold are better served by Wohngeld plus a small contribution gap than by Grundsicherung's full-welfare workflow.

Bürgergeld (Sozialgesetzbuch II). For people of working age below the Regelaltersgrenze who are not certified as fully and durably erwerbsgemindert, the parallel safety net is Bürgergeld under SGB II, administered by the Jobcenter. The Regelsätze are identical to Grundsicherung im Alter — €563 for a single adult in 2025. The administrative path differs sharply (Jobcenter vs. Sozialamt), the asset test under § 12 SGB II differs (€15,000 protected amount for the first year, falling to a more permissive long-term regime), and Bürgergeld carries Mitwirkungspflichten (cooperation duties, including job search) that Grundsicherung im Alter does not. The dividing line between the two systems is the Erwerbsminderungs-Bescheid: with full and durable Erwerbsminderung the applicant is entitled to Grundsicherung; without it they are routed to Bürgergeld.

Gesetzliche Renten and Erwerbsminderungsrenten (SGB VI). Most Grundsicherung-im-Alter recipients also draw a small contributory pension. The 2018 Rentenpaket introduced the Freibetrag on additional voluntary pension income (§ 82a SGB XII) that protects up to €224/month of pension from the means test, designed to reward people who paid into Riester or company-pension schemes during their working life. Without this Freibetrag, every euro of additional pension would have reduced Grundsicherung by a euro, eliminating any incentive to save during working life.

Pflegegeld and Pflegesachleistungen (SGB XI). For Grundsicherung recipients in need of nursing care, the long-term-care insurance (Pflegeversicherung) pays Pflegegeld for home care from a family member — €347 per month for Pflegegrad 2, €599 for Pflegegrad 3, €800 for Pflegegrad 4, and €990 for Pflegegrad 5 (2025 rates). Pflegegeld is not counted as income against Grundsicherung under § 13 Abs. 5 SGB XI in conjunction with § 82 Abs. 1 SGB XII. Pflegesachleistungen for professional care services are also non-countable. This protection is particularly important for elderly recipients living at home and supported by a family carer.

Hilfe zur Pflege (Siebtes Kapitel SGB XII). Where Pflegekasse benefits do not cover the full cost of care — almost universally true for full Heim-Unterbringung (residential nursing home placement) where monthly bills routinely reach €3,000-5,000 — the Sozialamt steps in under Hilfe zur Pflege. For a Grundsicherung recipient already in the welfare system, the transition to Hilfe zur Pflege is administratively seamless.

Rundfunkbeitrag-Befreiung (§ 4 RBStV). Grundsicherung recipients are exempt from the German broadcasting fee of €18.36/month per household. Application via the Beitragsservice (formerly GEZ); a copy of the Grundsicherungs-Bescheid suffices.

Sozialticket / Mobiltätsticket. Most German cities offer a discounted public-transport monthly ticket for Grundsicherung recipients — Berlin €9 instead of €58, Hamburg €27 instead of €58, Munich €34 instead of €58, Cologne €30 instead of €58.

Bildungs- und Teilhabepaket (§ 34 SGB XII). For Grundsicherungs-Haushalte with children, the federal Bildungs- und Teilhabepaket pays for school trips, school equipment, sports clubs, and music lessons. €15/month per child for social participation, plus actual costs for school items.

The Statistisches Bundesamt publishes annual data on Grundsicherung im Alter und bei Erwerbsminderung. The most recent confirmed figures relate to 31 December 2024, with provisional 2025 numbers released in March 2025.

Headline figures (2024). Approximately 1.2 million people received Grundsicherung im Alter und bei Erwerbsminderung in Germany at year-end 2024 — an increase of roughly 14% over the year-end 2019 figure of 1.06 million. Of the 1.2 million:

• ~705,000 received Grundsicherung im Alter (i.e. past the Regelaltersgrenze) — 59% of the total
• ~495,000 received Grundsicherung bei voller Erwerbsminderung (under Regelaltersgrenze) — 41% of the total

This split has shifted noticeably since 2010, when Erwerbsminderung cases were the larger share. The growth of the Alter-share reflects (a) the cumulative effect of broken pension contribution histories from the 1990s and 2000s, particularly for women who took long career breaks, (b) the gradual rise of the Regelaltersgrenze itself shifting some applicants between the two pillars, and (c) the 2020 Angehörigen-Entlastungs-Gesetz removing the family-recourse barrier and triggering an estimated 70,000 first-time elderly applications in 2020 alone.

Take-up rate. The Deutsches Institut für Wirtschaftsforschung (DIW Berlin) and the Bertelsmann-Stiftung have repeatedly estimated the gap between actual recipients and the eligible population. The 2018 estimate before the family-recourse reform was that 60% of the eligible elderly population (roughly 950,000 additional pensioners) did not file. The 2023 DIW update, post-reform, places the take-up gap at 30-40% — substantial improvement, but still well above the EU average. Verdeckte Altersarmut therefore remains a live policy problem, particularly among rural elderly women whose Renten lie just below subsistence and who fear the Gang zum Sozialamt.

Average benefit per recipient. €548/month average net Grundsicherung payment in 2024 (€563 Regelsatz target less average countable income plus average Mehrbedarfe and KdU components). Total federal spending on Grundsicherung im Alter und bei Erwerbsminderung in 2024 was approximately €11.2 billion — fully borne by the federal budget since the 2014 federalisation.

Demographic outlook to 2040. The DRV's Rentenversicherungsbericht 2024 and the Bundesinstitut für Bevölkerungsforschung project that the population aged 67+ will grow from 16.3 million in 2024 to ~21 million in 2040 — a 29% rise. Even if the per-capita risk of low pension income remains constant, the absolute number of Grundsicherung-im-Alter recipients will rise to ~900,000 by 2040 within the Alter pillar alone, taking total recipients past 1.5 million. The federal-budget burden on current trajectories would reach €17-19 billion by 2040.

Cohort-specific risks. Three groups face disproportionate Altersarmut risk in the cohorts approaching retirement in 2026-2040:

• Solo-self-employed people who opted out of the gesetzliche Rentenversicherung during the 1990s-2000s Riester-era and have inadequate private provision
• Long-term recipients of Hartz IV / Bürgergeld whose Rentenanwartschaften were built up under the very low gutgeschriebene Entgeltpunkte regime applicable to ALG-II recipients (capped at €205 of pensionable income per month)
• Women with long Kinder- and Pflegezeit gaps in their contribution record whose accumulated Entgeltpunkte fall below the Grundrentenzuschlag eligibility floor of 33 contribution years

Reform debates. Active proposals in the political mainstream as of 2026 include: (a) shifting Grundsicherung im Alter to be paid by the Deutsche Rentenversicherung on the same payment slip as the contributory pension (Austrian/Dutch model — would lift take-up sharply); (b) raising the §-82a-Freibetrag for voluntary pension income from €224 to €350/month to reward Riester savers more strongly; (c) integrating the Grundrente top-up with Grundsicherung in a single computation to avoid the current overlap; and (d) reducing the Schonbetrag asset test to harmonise with the more permissive Bürgergeld regime. The current Bundesregierung's coalition agreement signals support for proposals (a) and (b); proposals (c) and (d) face more resistance from the länder finance ministries. Whatever the eventual reform path, the long-run demographic arithmetic guarantees that Grundsicherung im Alter will remain a central pillar of the German welfare state through the 2030s and 2040s.
