Questions about the tax return

How do I avoid having to pay interest as well as tax?

Did you know that many taxpayers are expected to submit their income tax returns to the Tax and Customs Administration before 1 May 2022, especially if they still need to pay additional income tax for 2021. By filing their return early, they avoid having to pay at least 4% tax interest to the Tax and Customs Administration in addition to the income tax amount.

An alternative is to request a provisional income tax assessment for the amount still payable from the Tax and Customs Administration as soon as possible. If the tax assessment for 2021 is dated later than June 2022, you will also need to pay tax interest.

Many details have already been pre-filled on the tax return, do I need to do anything with those?

The Tax and Customs Administration has already filled in many details on your income tax return for 2021. It is important that you check these details carefully. If any changes or additions need to be made, let the Tax and Customs Administration know by filing a new tax return online.

Do I get a discount if I pay my taxes quickly?

You may be entitled to a prompt payment discount from the Tax and Customs Administration in certain cases if you pay the entire income tax amount owed in one go before the first payment date. Be aware, though, that in 2022 this applies to provisional income tax assessments for 2022 (which you can also pay in instalments) and not, for instance, to the income tax assessment for 2021, which you only receive after filing your tax return for that year.

How do I check whether a message claiming to be from the Tax and Customs Administration is real or fake?

Fraudsters regularly send letters or messages by WhatsApp, text message or email claiming to be the Tax and Customs Administration. While it appears as though these are sent by the Tax and Customs Administration, this is not always the case.

If you are unsure whether a message has been sent by the Tax and Customs Administration:

Log in to your personal tax account on the website of the Tax and Customs Administration: Mijn Belastingdienst .
If the message is shown on there, you can be certain that the Tax and Customs Administration sent it.
If you plan to transfer funds to the Tax and Customs Administration, always check the bank account number against the bank account numbers on this list.
The Tax and Customs Administration will never ask you to share your personal details or transfer money by email, WhatsApp or text message or via a link.
