Introduction
The Federal Ministry of Finance and the tax offices are currently reminding everyone of an important transitional regulation: Pensioners whose gross annual income (pension + any additional earnings) exceeds €24,000 must in many cases still submit a corrected tax benefit declaration – and the deadline is end of October 2026. The background is the gradual introduction of downstream pension taxation since 2005, combined with the Aktivrente reform and the new option of earning up to €2,000 per month (€24,000 per year) tax-free. Anyone exceeding this threshold and who previously benefited from a flat-rate or old tax relief must now make a correction/adjustment so that the tax office can determine the correct taxation. Missing the deadline risks back-payments including late-payment surcharges. Particularly affected are pensioners who, in addition to their statutory pension, have additional income or who fall under the Aktivrente regulation for the first time in 2026. Here are the most important facts: who is affected, what needs to be done, and why the end-of-October 2026 deadline is so critical.
Who is affected by the declaration obligation?
The obligation to submit a corrected tax benefit mainly affects the following groups of pensioners:
- Pension recipients whose total gross annual income (pension + capital income + additional earnings + possibly company pension) exceeds €24,000
- Persons who use the new Aktivrente regulation from 2026 (up to €2,000/month tax-free additional earnings) while simultaneously receiving a statutory pension
- Pensioners who in previous years benefited from a flat-rate or simplified tax relief that now has to be adjusted to the new rates (2026: 84% taxable portion for new pensioners)
- Anyone who has not yet submitted a final declaration for the 2025 tax year or transitional years and has been contacted by the tax office
Important: Anyone whose gross annual income remains below €24,000 is generally not required to file and does not need to submit a correction – unless the tax office explicitly requests a tax return.
What exactly needs to be corrected / declared?
The tax office requires a corrected tax benefit because:
- The taxable portion of the pension for new pensioners rises to 84% in 2026 (previously 83.5% in 2025).
- The Aktivrente allows up to €24,000 tax-free additional earnings – but only if this is correctly declared in the tax return and checked by the tax office.
- Many pensioners used simplified flat rates or allowances in the transitional years that must now be adjusted to the new basic tax-free allowance rates (2026: €12,348 for singles / €24,696 for married couples).
Without this correction, incorrect tax assessment may occur – either too much tax paid (no refund without application) or too little tax paid (back-payment + interest).
The important deadline: Until end of October 2026
The Federal Ministry of Finance and many tax offices have set the submission deadline for the corrected tax benefit at 31 October 2026 (for the 2025 tax year and transitional cases).
- Anyone who submits the required declaration (usually as a supplement or amendment to the tax return) by the end of October 2026 avoids late-payment surcharges and may still secure refunds.
- After 31 October 2026, late or non-submission can result in demands for payment plus 1% late surcharge per month.
- Tip: If you have already submitted a tax return for 2025, check whether the tax office has sent a letter requesting correction – many pensioners receive such letters in summer/autumn 2026.
Conclusion
Pensioners with annual income over €24,000 should urgently check whether they need to submit a corrected tax benefit – the deadline ends 31 October 2026. This becomes particularly important due to the new Aktivrente (up to €24,000 tax-free additional earnings) and the increased taxable portion (84% for new pensioners in 2026). Missing the deadline risks back-payments and interest. It’s best to prepare documents now with the help of wage tax assistance, a tax advisor, or via ELSTER. Current information and forms are available at www.bzst.de, www.finanzamt.nrw.de or the Federal Ministry of Finance website. Act in time – the €2,500 master craftsman bonus may be a nice extra, but a late tax return can quickly become much more expensive.
