Did your employer in the Netherlands deduct loonheffing every month? Advance payments are calculated according to general tables, without taking your allowances into account. The annual declaration to Belastingdienst allows you to recover the overpayment. We settle up to 5 years back, in Dutch, for a fixed fee of 400 PLN, with no commission on the refund.

Service price list - Netherlands
Have you worked in the Netherlands and did your employer withhold monthly loonheffing (Dutch wage tax)? Tax advances are calculated according to general tables - without taking into account your individual situation, allowances or expenses. Only the annual tax return with the Belastingdienst makes it possible to recover an overpayment and calculate the result according to the taxpayer's real annual situation.
FenixTax price: 400 PLN - fixed fee, 0% commission from the refund amount. The entire refund goes to you.
We have been settling foreign taxes for over 20 years. More than 48 000 handled cases and full correspondence with the Belastingdienst in Dutch.

Every person who meets the following conditions is entitled to apply for a refund:
It does not matter whether you worked for one month or the whole year. It is also irrelevant whether you still live in the Netherlands or have returned to Poland, because the settlement concerns the tax year in which Dutch income and tax advances were recorded by the employer and the Belastingdienst.

The amount of the refund depends on several factors:
| Annual income (EUR) | Rate (tax + contributions) |
|---|---|
| up to 38 883 | 35,75% |
| 38 883 - 78 426 | 37,56% |
| over 78 426 | 49,50% |
The first-band rate includes income tax and social insurance contributions (AOW 17,90%, Anw 0,10%, Wlz 9,65%).
| Credit | Maximum amount 2026 | For whom |
|---|---|---|
| Algemene heffingskorting (general tax credit) | 3 115 EUR | Every taxpayer (reduced from income of 29 736 EUR) |
| Arbeidskorting (employment tax credit) | 5 685 EUR | Persons with employment income (reduced from 45 592 EUR) |
Together up to 8 800 EUR of annual tax credits. These amounts reduce your tax directly - not your income.
Full allowances are available to persons with the status of a qualifying foreign taxpayer (kwalificerend buitenlands belastingplichtige) - if your income from the Netherlands constitutes at least 90% of all income in the relevant tax year and you prove this with an EU/EWR certificate from the Polish tax office.
Example: Jan earned 26 000 EUR in the Netherlands and about 500 EUR in Poland. The Dutch share is 98% - so he meets the 90% condition and is entitled to full tax credits.
If you do not meet the 90% condition, you can still file a return, but without the full allowances. An overpayment may have arisen for other reasons, for example because advances were too high.
Basic documents:
For full allowances (90% rule):
You do not have a Jaaropgave? Then we need the last payslip (salarisstrook) or the employer's details. We request the required information from the Belastingdienst.

A tax return in the Netherlands can be submitted up to 5 years back. In 2026, you can settle the following years:
| Tax year | Final deadline |
|---|---|
| 2025 | 31 December 2030 |
| 2024 | 31 December 2029 |
| 2023 | 31 December 2028 |
| 2022 | 31 December 2027 |
| 2021 | 31 December 2026 |
Important: For the year 2021, less than 8 months remain - act now if you have not yet filed the return for this year.
The Belastingdienst issues two types of assessments: voorlopige aanslag (provisional assessment - faster payment) and aanslag (final assessment).
| Form | For whom |
|---|---|
| Aangifte C | Non-residents - persons not registered in the Netherlands (the most common case for Polish employees) |
| Aangifte P | Residents - persons registered in the Netherlands for the whole year |
| Form M | Persons who registered or deregistered during the year |
| Form F | Settlement of a deceased person (by the heirs) |
Most Polish employees file Aangifte C. You do not have to determine yourself which form applies to you - we take care of that.
If you work in the Netherlands and are tax resident in Poland, you must report the Dutch income in the Polish return PIT-36 with PIT/ZG attachment. The Polish-Dutch double taxation treaty allows the tax paid in the Netherlands to be credited. If additional tax arises, the abolition relief may be applied (since 2023: maximum 1 360 PLN).
The tax refund from the Netherlands itself is not income taxable in Poland.
At every stage, you know what has been sent, what the authority may still request and what the expected next step is. We serve clients online from all over Poland and at more than 140 service points throughout the country.

The higher your refund, the more cost-effective our fixed fee is. With a fixed fee, the cost does not grow together with the refund, so the full financial benefit from a higher overpayment remains with you.

Standard processing takes 3 to 6 months from submission of the complete return. The Belastingdienst first issues a provisional assessment (voorlopige aanslag) and then the final assessment (aanslag). Returns submitted by 1 April are processed faster - a refund may even be possible after 2-3 months. In complicated cases or additional checks, the process can take up to 12 months.
The years 2021, 2022, 2023, 2024 and 2025. The right expires 5 years after the end of the tax year. For 2021, the final deadline is 31 December 2026, so less than 8 months remain.
400 PLN for an individual settlement and 200 PLN for a nil settlement. This is a fixed fee - we do not charge a percentage commission from the refund amount. Whether you receive 300 EUR or 3 000 EUR back, the price remains the same.
Loonheffing is the Dutch payroll tax withheld monthly by the employer. It includes income tax (inkomstenbelasting) and social insurance contributions (volksverzekeringen - AOW, Anw, Wlz). The advances are calculated according to general tables without individual allowances - this creates overpayments that can be reclaimed through the return.
The Jaaropgave is the annual income statement issued by the employer - the Dutch equivalent of the Polish PIT-11. It should be delivered by the end of March of the following year. If you have not received it, you can request a duplicate from the employer. If there is no contact anymore, we can request the required data from the Belastingdienst.
It is an official document from the Polish tax office confirming your income earned in Poland and possibly in other countries outside the Netherlands. The Belastingdienst requires it from persons applying for the status of a qualifying foreign taxpayer under the 90% rule.
Yes. As a Polish tax resident, you must report all income, including Dutch income, in the PIT-36 return with PIT/ZG attachment. This does not mean double taxation - the double taxation treaty allows the tax paid in the Netherlands to be credited.
No. A refund of a tax overpayment is not income taxable in Poland. You do not have to report the amount received.
The BSN (Burgerservicenummer) is assigned when registering in the Netherlands. If you worked legally, you probably already have it - it appears on the Jaaropgave, payslips or official correspondence. If you have never received a BSN, we can help with the application (cost: 300 PLN).
Yes, if two conditions are met: (1) your income from the Netherlands constitutes at least 90% of your worldwide income, (2) the joint income of you and your spouse comes at least 90% from the Netherlands. The partner must have a BSN. Joint settlement can significantly increase the refund through the partner's general tax credit.
We translate letters from the Belastingdienst and reply in Dutch on your behalf. You do not need to know the language. If you receive a letter that you cannot answer, contact us.
Voorlopige aanslag is a provisional assessment in which the Belastingdienst estimates your tax on the basis of the submitted return. It can allow faster payment. Aanslag is the final assessment after full verification. If there are differences, you pay extra or receive an additional refund.
Yes. If your previous settlement was incomplete or incorrect, for example because allowances were missing, you can file a correction. The correction is a complete new return and can be submitted up to 5 years after the end of the tax year.
In 2026, three bands apply: 35,75% up to 38 883 EUR, 37,56% from 38 883 to 78 426 EUR and 49,50% above 78 426 EUR. The first band includes income tax and social insurance contributions. Most Polish employees fall into the first band.
The two most important are Algemene heffingskorting (general tax credit - up to 3 115 EUR in 2026) and Arbeidskorting (employment tax credit - up to 5 685 EUR in 2026). They are available to persons whose Dutch income constitutes at least 90% of all income. The credits reduce tax directly - not income.
Yes. The form of employment does not matter. What matters is that the employer, in this case the agency, withheld loonheffing. Temporary employment agencies issue a Jaaropgave just like direct employers.
Abolition relief concerns the Polish tax settlement. If, after applying proportional credit in PIT-36, additional tax arises in Poland, this relief reduces the amount. Since 2023, it is limited to 1 360 PLN per year. A Dutch tax refund may offset a possible Polish tax surcharge.
DigiD to cyfrowy login do holenderskich urzędów, w tym do portalu Mijn Belastingdienst, gdzie widać status zeznania i decyzje. Mieszkając w Polsce, trudno go uzyskać, bo wymaga potwierdzenia tożsamości w Holandii. Dlatego status sprawy monitorujemy za klientów i informujemy o każdej decyzji, a pismo z urzędu wystarczy przesłać do biura.
Zorgtoeslag to dopłata do obowiązkowego holenderskiego ubezpieczenia zdrowotnego dla osób o niższych dochodach, wypłacana przez urząd Belastingdienst Toeslagen. Przysługuje także Polakom pracującym w Holandii i można o nią wystąpić również za poprzedni rok. To osobna procedura obok rozliczenia podatku: zobacz usługę dodatek do ubezpieczenia Zorgtoeslag.
Jeśli rozliczenie podatku w Holandii jest obowiązkowe (na przykład po wezwaniu z urzędu albo przy dopłacie powyżej progu), Belastingdienst może naliczyć grzywnę i odsetki od zaległości, a podatek oszacować na niekorzyść podatnika. Osoby mieszkające w Polsce mają też obowiązek wykazania holenderskich dochodów w polskim zeznaniu (PIT-36 z załącznikiem PIT/ZG). W praktyce rozliczenie zwykle się opłaca, bo większość pracujących w Holandii ma nadpłatę do odzyskania.
Tak, i to właśnie przy pracy sezonowej na terenie Holandii zwroty bywają najwyższe w stosunku do zarobków. Zaliczki na podatek pobierane są tak, jakby dochód był osiągany przez cały rok, więc przy krótszym okresie pracy duża część ulg pozostaje niewykorzystana i powstaje nadpłata. Wystarczy kopia karty podatkowej Jaaropgaaf od pracodawcy lub paski wypłat.
Standardowy termin złożenia deklaracji za poprzedni rok to 1 maja. Na wniosek można uzyskać przedłużenie, a jeśli urząd przysłał wezwanie, obowiązuje termin wskazany w piśmie. Rozliczenie dobrowolne, nastawione na zwrot, można złożyć nawet do pięciu lat wstecz.
Po złożeniu zeznania sprawa czeka na rozpatrzenie przez Belastingdienst, który najpierw wydaje decyzję wstępną (voorlopige aanslag), a potem ostateczną (aanslag). O postępach klient jest informowany na bieżąco, a o status można w każdej chwili zapytać w biurze, telefonicznie lub mailowo.
Zasiłek rodzinny na dzieci (Kinderbijslag) to osobne świadczenie wypłacane przez urząd SVB, niezależne od rozliczenia podatkowego. Otrzymanie zwrotu podatku nie wpływa na prawo do zasiłku ani odwrotnie. W ramach rozliczenia podatku sprawdzamy natomiast ulgi podatkowe, które przysługują między innymi osobom utrzymującym rodzinę.
Tak, rozliczenie podatku z Holandii w całości załatwisz zdalnie: dokumenty przesyłasz przez formularz na stronie lub mailem, komplet do podpisu przychodzi elektronicznie albo pocztą, a zwrot trafia z urzędu bezpośrednio na konto, także polskie. Dla osób, które wolą kontakt na miejscu, dostępna jest sieć punktów obsługi w całej Polsce.
Dochody rozlicza się w każdym kraju według tamtejszych zasad. W Holandii wysokość polskich dochodów wpływa na prawo do pełnych ulg (zasada 90 procent, potwierdzana zaświadczeniem UE/WE), a w Polsce holenderskie dochody wykazuje się w PIT-36 z załącznikiem PIT/ZG. Takie mieszane sytuacje to codzienność przy pracy transgranicznej i standardowy zakres usługi.
