Top-Up Earner Allowances Miscalculated — Why Almost None of Your Wage Reaches You

You work, you receive top-up Bürgergeld — and yet at the end of the month barely more money is left than if you had not worked at all. When it feels like that, it is often not coincidence but a calculation error in your decision letter. As a top-up earner (Aufstocker) — a working person whose wage is not enough to cover their own needs and who therefore additionally claims Bürgergeld — you are entitled to several allowances stacked on top of each other. Many Jobcenters, however, only take part of them into account.

This page explains the complete allowance package for top-up earners under § 11b SGB II and shows, using two worked examples, how the 20/30/10 percent tier scale affects your monthly income.

The Most Important Points in 30 Seconds

  • As a top-up earner (Aufstocker), your gross earned income is reduced by a multi-stage package of allowances — basic deduction, social insurance contributions, actual work-related expenses, old-age provision, and the percentage tier.
  • Basic deduction of 100 €/month (§ 11b Abs. 2 SGB II) — covers a flat-rate work-expenses share of 15.33 €, an insurance flat rate of 30 €, and an old-age provision share.
  • Earned-income tier (§ 11b Abs. 3 SGB II): 20 % of the income share between 100 € and 520 €, 30 % between 520 € and 1,000 €, 10 % between 1,000 € and 1,200 € (or 1,500 € with a child).
  • Old-age provision allowance up to 50 €/month on top (Riester, Rürup).
  • Car liability insurance and statutory social insurance contributions are deducted in full, in their actual amount, on top.
  • Objection deadline: one month from receipt of the decision. Retroactively up to one year via § 44 SGB X.

Why Does This Happen So Often to Top-Up Earners?

Top-up earners (Aufstocker) are the most complicated calculation case in Bürgergeld. With them both worlds collide at once: tax and social-insurance law (for the wage) and SGB II (for the offsetting). The calculation sheet has to first deduct statutory deductions from the gross wage, then the basic deductions under § 11b Abs. 1 and 2, then the percentage tier under Abs. 3 — and only the result is offset against the requirement.

Many caseworkers deduct only the basic 100 € deduction as a flat rate and "forget" the tier. Or they apply the tier but leave out the old-age provision allowance. Or they strike the car liability insurance because they confuse it with comprehensive coverage. Each of these errors easily costs you 50 to 200 € per month — often more when several errors stack up.

Example 1 — Frau B., part-time parcel courier, top-up earner:

  • Gross 850 €/month, net after tax and social insurance: 720 €
  • Correctly deductible: 100 € basic deduction + 20 % of 420 € (income share 100–520 €) = 84 € + 30 % of 200 € (income share 520–720 €) = 60 € → total allowances 244 €
  • Offsettable would therefore be 720 € − 244 € = 476 €
  • But the Jobcenter only deducts the 100-euro basic amount and offsets 620 €.
  • Difference: 144 € less Bürgergeld per month, even though Frau B. is working.

That is exactly the signal top-up earners feel at the end of the month: "There is nothing left from my work." Often this is a calculation error, not a law of nature.

Your Rights in Concrete Terms

Top-up earners are entitled to all four levels of deduction in parallel. If a level is missing in the calculation sheet, the decision is challengeable.

1. Basic Deduction 100 € (§ 11b Abs. 2 S. 1 SGB II)

Deducted from every earned income — including mini-jobs, part-time work, or just a few hours per week. It contains as a flat rate: a work-expenses flat rate of 15.33 €, an insurance flat rate of 30 €, and a share for private old-age provision.

2. Actual Work Expenses Instead of the Flat Rate (§ 11b Abs. 1 Nr. 5 SGB II)

If your real work expenses (Werbungskosten) exceed the flat 15.33 €, the excess amount must additionally be deducted. Typical for top-up earners: travel costs at 0.20 € per kilometre one-way, work clothes, tools, union dues, professional liability insurance.

3. Old-Age Provision Allowance up to 50 € (§ 11b Abs. 1 Nr. 4 SGB II)

Contributions to state-subsidised contracts — Riester or Rürup — can be deducted up to 50 € per month on top of the basic deduction. Non-subsidised private pensions do not count. Proof comes from the contract itself (entitlement to the subsidy, support under § 10a EStG).

4. Car Liability Insurance and Statutory Social Insurance (§ 11b Abs. 1 Nr. 3 SGB II)

Statutorily prescribed insurances are deducted in their full actual amount. This includes statutory social insurance contributions if you are subject to mandatory cover, plus the car liability insurance (not comprehensive coverage). The contribution is thereby effectively secured twice — once as a flat rate via the 30 € insurance flat rate inside the basic deduction (which covers other insurance) and once concretely via the liability premium.

5. Earned-Income Tier 20 %/30 %/10 % (§ 11b Abs. 3 SGB II)

For each income share above the 100 € threshold, in addition:

  • 20 % of the gross income share between 100 € and 520 €
  • 30 % of the income share between 520 € and 1,000 € (the core incentive for top-up earners with part-time jobs)
  • 10 % of the income share between 1,000 € and 1,200 € (or 1,500 € for persons with at least one minor child in the household community (Bedarfsgemeinschaft, BG))

6. Review Application under § 44 SGB X

If errors have been sitting in the calculation sheet for months, the Überprüfungsantrag (review application) reaches up to one year retroactively — even when the objection deadline has long passed.

Current Case Law

The Bundessozialgericht (BSG) has confirmed several times that the allowances under § 11b SGB II must be calculated cumulatively — every level applies independently, double deductions are to be avoided, but no level may be flat-rate "offset" with another. Anyone working as a top-up earner is entitled to the basic deduction and the percentage tier alongside one another. [URTEIL-REFERENZ]

On the car liability insurance, case law has clarified: it is to be deducted as a statutorily prescribed insurance in actual amount, regardless of the flat 30-euro insurance share inside the basic deduction. The flat rate covers other insurances (private liability, household contents, accident), not the mandatory car liability cover. [URTEIL-REFERENZ]

For employees with fluctuating income (shift bonuses, tips, weekend duties — typical in parcel delivery, cleaning, catering), the Zuflussprinzip (inflow principle) applies: what is offset is what actually arrived in the account in the respective month. A flat-rate averaging by the Jobcenter is only permissible when it works in favour of the entitled person. [URTEIL-REFERENZ]

How to Proceed Now

  1. Request the calculation sheet. Every top-up earner decision contains a multi-page calculation sheet in the annex. If it is missing, request it under § 25 SGB X (file inspection). Without the sheet, no error check is possible.
  2. Run the four-level check. In the sheet, find the lines for (a) basic deduction, (b) old-age provision, (c) car liability, (d) tier 20/30/10 %. If one of the four lines is missing, that is a starting point for the objection.
  3. Counter-calculate actual work expenses. Travel kilometres × 2 × working days × 0.20 € = monthly travel costs. If the result exceeds 15.33 €, the excess amount has to be additionally deducted. Collect receipts (fuel slips, route-planner printouts, time records).
  4. Have the old-age provision proof ready. Riester or Rürup annual statement from your contract file — it shows the monthly contribution that is deductible up to 50 € on top.
  5. File the objection — informal, deadline-preserving. Within one month of delivery: "I hereby file an objection against the decision dated [date], file number [Aktenzeichen]. The allowances under § 11b SGB II were not fully taken into account. Reasons to follow." Registered letter with delivery confirmation, or in person with a date stamp.
  6. Submit the reasoning as a target/actual comparison. On one page, set side by side: "This is how the Jobcenter calculated — this is how it should have calculated." The euro difference is your monthly damage. That convinces the objection office most quickly.

Avoiding Typical Mistakes

  • Forgetting the tier altogether. Many decisions only show the 100-euro basic amount, with no line for the 20/30/10 % tier. This is the single most expensive error for top-up earners — at 850 € net it quickly costs 140 €/month.
  • The mini-job myth: "Tier only for proper employment." Wrong. The tier also applies to 400-euro mini-jobs — from a 400-euro mini-job only 240 € are offset after the basic deduction plus 20 % tier, not 300 €.
  • Confusing car liability with comprehensive coverage. Only the statutorily prescribed liability insurance is deducted, not the voluntary comprehensive policy. Anyone listing both as "car insurance" risks the Jobcenter striking the liability cover too. The insurance premium notice itemises both separately — attach this as proof.
  • Overlooking the old-age provision allowance. Anyone who stated in the application that they pay into a Riester contract must have up to 50 €/month additionally deducted. If the line "old-age provision" does not appear in the sheet, there is a calculation error — regardless of the size of the rest of the income.

Frequently Asked Questions

Is working as a top-up earner even worth it when so little remains in the end?

Yes — if the calculation is correct. The legislator introduced the earned-income tier precisely so that part of every euro you earn stays with you. At a gross of 850 € in part-time work, the correct calculation produces around 244 € in allowances — that is 244 € more than the bare Regelbedarf (standard requirement) without employment. Anyone who feels "it does not pay" should have their decision checked: in most cases the tier is not deducted in full.

Does the 20/30 percent tier also apply to a 400-euro mini-job?

Yes. The mini-job myth is stubborn but wrong. With a 400-euro mini-job, first the 100-euro basic deduction is taken, then 20 % of the income share between 100 € and 400 € (i.e. 60 €) as the tier. In total only 240 € of the 400 € mini-job are offset against the requirement — so you effectively keep 160 € extra. It pays off if you know how.

Will my car liability insurance be deducted on top of the 30-euro insurance flat rate?

Yes, if you are a vehicle owner. The 30-euro flat rate inside the basic deduction covers "normal" insurance (private liability, household contents). The statutorily prescribed car liability insurance is deducted in actual amount on top under § 11b Abs. 1 Nr. 3 SGB II. Important: only the liability share, not the voluntary comprehensive coverage — the insurer itemises both positions separately.

How do I calculate fluctuating wages with shift bonuses?

What counts is the actual inflow in the respective month, not the average. The Jobcenter uses the Zuflussprinzip (inflow principle). In good months your income is higher, hence the Bürgergeld claim is lower. In weaker months the reverse. Submit the payslip every month — automatic averaging is only permitted if it works in your favour.

Until when can I have an old, faulty decision corrected?

Within one month of delivery via objection. After that, the Überprüfungsantrag (review application) under § 44 SGB X reaches up to one year retroactively — even without an objection. If your decisions over the last twelve months have forgotten the tier or the old-age provision, you can demand a back payment for that entire period. That quickly amounts to four-figure sums.
