The main levers

Pay into pillar 3a every year.
Buy into the pension fund if you have a gap.
Claim commuting, meals and training costs.
Deduct childcare and donations.
Check medical costs and interest on debts.
Time large deductions in high-income years.
Choose a municipality with a lower tax rate when you move.

Know your marginal rate

A deduction is worth your marginal rate. At 30 %, a CHF 5,000 deduction saves CHF 1,500. Use your canton's calculator to find your rate.

Keep it legal and documented

Keep receipts and declare all income and assets. See the effect of a deduction with the tax saving calculator.
