Water authority tax

You do not have an account number for water authority tax. Instead, you use your DigiD to identify yourself and to log in to My Taxes.

Tip: you do not have to tell us you are moving for water authority tax. You should inform your municipality of your move and your water authority tax will be automatically adjusted (if it has changed).
