Hi all,

I have some questions about my supplemental declaration and hopefully somebody will be able to provide me some guidance.

In 2020 I've lived in Neuchatel canton during January and the rest of the year in canton VAUD. I'm currently on a Permit B with a salary lower than 120.000CHF a year.

I wanted to declare my 3rd pillar through the supplemental declaration form but I'm not sure how to go on about it.

• Do I need to fill the supplemental declaration form for both cantons?
• Should I declare a pro-rated 3rd pillar value for both cantons?
• How do I request a "numéro de contribuable"? I didn't receive any letter from the canton regarding this.

Thank you in advance!

You will have to do so in both cantons.

The relevant form says "numéro de contribuable" (si connu).

If known. Logically you leave it blank if you do not know it.

Thank you for the quick answer!
