The tax deadline is 1 May, but you can push it to 1 September for free
If you are not ready to file by 1 May, request uitstel online before that date and get 4 extra months to 1 September at no cost. And even if you were never sent a return, you can file voluntarily up to 5 years back to claim refunds. Note: tax interest (belastingrente) can apply if you end up owing.
Get the rest of it, in your own language.
MAS reads your IND letter, checks whether an employer can legally sponsor you, and finds work that will actually take you. Free, no account.
