Six questions about the tax service

The executives of the Tax Service FNV (de AOb is part of the FNV) will help you and your partner complete your tax return and allowances free of charge. During the year, approximately 2.300 well-trained executives complete approximately 60 tax returns and approximately 20 allowances. Filling in takes place at about 120 locations in the Netherlands in the months of March and April. The rest of the year is filled in at the FNV locations.

Below are a few questions we can answer: 

  • How do I log in?
  • My details do not match the details that the Tax and Customs Administration has already entered. What now?
  • I have incurred costs in connection with illness, study, alimony, etc. Can I enter these?

Yes, this service is a nice advantage for you AOb-members. Unfortunately, we cannot handle declarations from self-employed persons without employees.

With an authorization code, the Tax and Customs Administration gives permission for someone else to file your tax return. We cannot help you without an authorization code.

  • Do you file a tax return together with your partner? Then you need two authorization codes: one for yourself and one for your partner
  • The authorization code applies to income tax and allowances
  • Bring the authorization code and your social security number with you to your appointment (or have them to hand on the phone). With this information we can activate your authorization
  1. Go to authorize.digid.nl
  2. Under 'Frequently requested permissions', choose: Income tax and allowances
  3. Click on the orange button: 'Authorize someone'
  4. Click on log in with DigiD and log in
  5. Choose the period in which the authorization is valid: up to and including 31-12-2024
  6. Enter your email address or choose Skip
  7. Click Confirm

The authorization code is immediately available.

Have you previously used Belastingservice FNV and do you have a DigiD? During the application you will see the Federation of Dutch Trade Unions (FNV). Choose that option and you'll have authorized us right away. An authorization code is then not required.

  1. Call DigiD Authorization on: 088 – 123 65 55, available Monday to Friday from 8.00 a.m. to 22.00 p.m.

  2. Provide your BSN number and request an authorization code for income tax and allowances (this is one code). Tip: It will go faster if you do not mention that you are doing this on behalf of the FNV.

  3. You will receive the authorization code by post at home. This takes about 5 working days. Please keep this in mind when scheduling an appointment.
