Value added tax

If your company is in the VAT register, remember to file VAT returns regularly even if you have not had any business activities. 

Payment arrangement

If you have temporary financial difficulties and you need more time for paying your taxes, you can ask for a payment arrangement.

Request a payment arrangement in MyTax. You will get your decision faster in MyTax than by calling.
