What is it about?
Have you paid too much salary in 2025? Or calculated too much or too little tax exemption? If so, we can correct the salaries at your request. We will submit corrected declarations for 2025 in the advance tax levy. Both the corrected declarations and the original declarations are done via Finprof.
Finprof is an application of the FPS Finance to submit your electronic declarations in the advance tax levy.
For the income year 2025, these corrections can still be made legally and administratively until 31 August 2026.
Why the deadlines of 15 May 2026 and 10 July 2026?
Although Finprof closes on 31 August 2026, we take the holiday period into account. Because many corrections need to be processed and there is less staff present during that time, we ask you to send us the corrections no later than the following dates:
- by 15 May 2026 for corrections to the tax exemptions
- by 10 July 2026 for other corrections
What happens after Finprof closes on 31 August 2026?
After 31 August 2026, corrections for 2025 are still possible but must be made as follows:
- Either via an objection
- Or by submitting a complementary or corrective form
We will explain these two options below.
Via an objection
For a negative correction with repayment of the advance tax levy, you must submit an objection.
You should preferably avoid this type of correction because the FPS Finance assumes a registration for natural persons from 31 August. In principle, it is therefore no longer possible to obtain repayment of the registered advance tax levy on the personal income tax (PIT).
The processing of the objection may also take some time.
Furthermore, you have no guarantee that the advance tax levy will be repaid if it was originally registered due to non-payment without a valid reason.
By submitting a complementary or corrective form
The second option is to submit a corrective or complementary form.
If you want to cancel the salary without changing the amount of the declared advance tax levy, you must submit a corrective form;
If you want to declare an additional salary, and if withholding tax is due, you must pay fines and default interest for late payment.
In both cases, no invoice for the advance tax levy is issued. The proof is either your tax deduction if the objection is approved by the FPS Finance, or your registration in the case of an additional advance tax levy.
