Result

Expected after the year: You pay€ 6.854
Income tax: refund or bill− € 6.854
Income tax due for the year€ 13.787
Wage tax withheld€ 6.932

What to do now

  • Two employers apply the tax credit. Ask one of them to stop (loonheffingskorting "nee"), or set money aside for the bill.
  • Ask for a provisional assessment in Mijn Belastingdienst and pay about € 2.285 a month, or save it, so the bill does not arrive in one go.

The tax settlement comes with your final assessment after you file (from 1 March); allowances are settled when Dienst Toeslagen makes the final calculation, usually in the second half of the year after.

Estimate for employees below state pension age. Wage tax is approximated per employer over the year (bonuses and holiday pay at the special rate even out over the year). Childcare allowance and the working-parent credit are not included. The Belastingdienst and Dienst Toeslagen decide the final amounts.
