When completing the wage tax return, many employers make the mistake of incorrectly combining an employee's citizen service number (BSN) and date of birth. If the Tax Authorities discover this error, the employer will receive an error report. But what should you do if you have made this mistake?

In order to fill in the BSN and date of birth correctly, it is important to correctly copy the data from the employee's ID. You will find the BSN on your identity document, such as a passport or identity card, and you must also copy the date of birth from this document according to the Dutch date format (day-month-year).

If a date of birth is incomplete, use these standard corrections:

• Is the day not known? Then use the 16th.
• Is the month not known? Then choose July 1.
• Is the year not known? Then choose July 1 of the estimated year of birth.

If you have accidentally entered an incorrect BSN, you must withdraw the income relationship with the incorrect BSN for all tax return periods. You then register the employee again with the correct BSN. You can do this in one correction message. If there is an error in the date of birth, correct the date by resubmitting the income ratio with the correct date of birth.

Please note: if you have made the same mistake in multiple payroll returns, you must correct all those returns.

Have you used the correct data, but still received an error report? Then send a response with a copy of the ID to the Tax Authorities to resolve the problem.

This news is useful for employers who want to avoid being fined for errors in their payroll declaration. It helps them understand how to quickly and correctly recover their data.
