Change your tax credits
If you want us to change the tax credit on your pension or benefit, you can let us know via My SVB. You should also remember to change the tax credit with your pension fund and make sure this change starts in the same month.
Make sure that the tax credit is applied to only 1 of your sources of incomes at any given time. Otherwise you will pay too little tax.
Go to My SVB and log in with your DigiD to change your tax credit . If you live in Europe and you do not have a DigiD, you can log in with a valid EU Login .
