Filing your tax return costs time and nerves. The Baselland tax authority checks closely, but offers some very attractive optimisation opportunities for the 2025 tax period — especially in the area of pension provision. That makes it all the more important to know your legal options — and to use the statutory maximums in full. Our approach to your financial planning is simple: you pay only what you actually owe.
We have analysed the five most effective deductions and show you how to use them well.

1. Insurance & Health Insurance Premiums
Your private premiums for health, accident, or life insurance — and savings interest — are deductible as a lump sum.
Maximum deduction (married):
- CHF 4,000 for cantonal tax.
- CHF 3,700 for direct federal tax.
Maximum deduction (single):
- CHF 2,000 for cantonal tax.
- CHF 1,800 for direct federal tax.
The FIN tip: Direct federal tax rewards taxpayers without a 2nd or 3rd pillar significantly! If you have not contributed to a pension fund or Pillar 3a, your federal deduction increases to CHF 5,550 for married couples or CHF 2,700 for singles (the cantonal deduction stays the same). Do not forget the additional deduction per child: this adds another CHF 450 at cantonal level and CHF 700 at federal level.

2. Job-Related Education and Training Costs
The tax authorities reward investment in your education. You can deduct self-paid costs for job-related training and continuing education (provided you already hold a Secondary II qualification or are over 20 years old).
Maximum deduction:
- CHF 12,000 for cantonal tax.
- CHF 13,000 for direct federal tax.
The FIN tip: Since the federal deduction at CHF 13,000 is CHF 1,000 higher than the cantonal one (CHF 12,000), do the math for expensive courses. It can be worth splitting the invoicing in agreement with the institution across year-end. That way you reach the maximum on both levels in two consecutive tax periods.

3. Pillar 3a (Restricted Private Pension)
The classic of tax optimisation. Contributions to approved Pillar 3a solutions reduce your taxable income directly.
- Maximum deduction (with pension fund): CHF 7,258.
- Maximum deduction (without pension fund): 20 % of net earned income, up to CHF 36,288.
The FIN tip: Important new option that already applies to the 2025 tax year! From 2026, working individuals can — for the first time, for the year 2025 — additionally pay contributions as a buy-in into Pillar 3a, provided contribution gaps have arisen in the previous ten years. We also recommend spreading the regular 3a balance across up to three accounts to break the tax progression on later withdrawal.

4. Pension Fund Buy-In (2nd Pillar)
Voluntary buy-ins into your pension fund are fully deductible and noticeably reduce your taxable income.
Maximum deduction: limited by your individual coverage gap (see your current pension certificate).
The FIN tip: Mind the statutory three-year lock-up period. If you withdraw capital from your pension fund within three years of a buy-in (e.g. for home ownership), the tax authority reverses the deduction and opens a subsequent assessment procedure. Heads-up: a buy-in must also not be financed from Pillar 3a funds if it is to remain tax-deductible!

5. Third-Party Childcare Costs
If your children (under 14) are looked after externally (e.g. day care, child-minder), you can deduct those costs — provided both parents work, study, or are invalid.
Maximum deduction (per child):
- CHF 10,000 for cantonal tax.
- CHF 25,800 for direct federal tax.
The FIN tip: Canton Basel-Landschaft is strict about separating costs: only pure childcare costs are deductible. Any meal costs at day care count as living costs and are cut! In addition, any direct payments (subsidies, vouchers) from the community must be deducted from the invoice amount first. Keep all detailed receipts.
