Application for extended deadline for submitting a client's tax return

Accountants and auditors can apply for a 30-day extension for submitting the tax return on behalf of their clients.

You can upload your client lists, making it easier to apply for several clients.

You will see the result of the applications immediately. You can see your previously submitted applications and whether the clients have submitted their tax return, have already received an extended deadline or cannot be granted an extension for other reasons.

The deadline for applying for deferred submission of the tax return for clients is

  • 30 April for wage earners and pensioners (Since 30 April this year falls on a Saturday, you can still submit your tax return on Monday 2 May and be within the deadline.)
  • 31 May for businesses

You will not be granted an extension beyond 30 days. If a business does not submit its tax return, or submits after the deadline, it may be issued an enforcement fine.
