Many people owe unexpected additional income tax for 2014. This is because last year the general tax credit and the employment tax credit became income related, while this was not yet fully taken into account in the wage tax tables for the payroll. This was especially true for special payments such as bonuses. This was covered extensively in the media.

Will the same happen in 2015?

No, as of January 1, 2015 the wage tax tables are adjusted so that the wage tax paid will be in line with the eventual income tax due.
