How to change your tax address with the Bizkaia Tax Office
If you've moved, this is what you have to report and when.
In a nutshell
- If you move, you have to report your new tax address to the Tax Office.
- If you're self-employed, it's done with form 036 within a short deadline.
- If you're coming from outside Bizkaia, the tax office in charge of you may change.
Your tax address (domicilio fiscal) is where the Tax Office sends its letters, and it decides which tax office you belong to. If you move, you have to tell them.
When you have to report it
As soon as you move. If you have a business activity, the change is reported with the census declaration and the deadlines are short. If you don't report it, notices may go to your old home and count as received.
Cases that change something else
- If you move within Bizkaia: only the address changes.
- If you come from Álava, Gipuzkoa or elsewhere in Spain: you start paying tax with the Bizkaia Tax Office. There are rules on from when.
- If you work from home: the address of your activity also has to change.
- If you have premises: the premises don't change, only your tax address.
Social Security is separate. If you're self-employed, it's worth changing your address with Social Security too.
Frequently asked questions
Do I also have to change it on the local register (padrón)?
Yes, the padrón belongs to the town council and is a different procedure. The Tax Office may use it to check where you live.
