I moved to Switzerland 6 months ago and I live and work in Basel Stadt. I recently paid the full annual amount into a 3a pension. I have a B permit and I get taxed at source, does anybody know how I go about claiming back the tax that I should of saved by paying into pillar 3a? If so how do I go about doing this.

Also is there a way that I can get the tax saving for next year's 3a deductions deducted at source so I do not have to claim it back? Is it best to pay in the annual amount in full or should I do this monthly, any advantages to either method.

Many Thanks

3a Accounts earn higher interest rates and are tax free, Hence, it is beneficial to pay the full contribution early in the year.
