Avoid these common mistakes

These mistakes can delay or block your application

  1. 01

    Waiting too long

    The TOU deadline is March 31. After that, your request is postponed to the next year.

    Solution : Run your estimate as soon as possible and order the TOU service before the deadline.

  2. 02

    Sending after the deadline

    Late applications may be refused or delayed by an entire year.

    Solution : Submit your application before March 31 for the current tax year. The sooner the better.

  3. 03

    Forgetting important deductions

    Transport, meals, insurance - every forgotten deduction reduces your potential savings.

    Solution : Use our calculator which automatically checks all possible deductions for your situation.

  4. 04

    Not checking your data

    Errors in your salary certificate numbers can distort the estimate and TOU request.

    Solution : Double-check boxes 11 and 12 on your salary certificate before running the estimate.
