Recommended products
Introduction
You've opened a 3a account and you're funding it regularly? Congratulations, you're taking a giant step towards financial independence! But one crucial question deserves your attention: How to optimize your 3a from a tax perspective? What if the solution was to stagger your withdrawals?
The 3rd pillar in brief
THE account 3a is an individual savings plan designed for supplementing income from the AVS (1st pillar) and pension fund (2nd pillar). His goal? Maintaining your standard of living after retirement.
But did you know that it can also be used for:
✅ Leave Switzerland permanently
✅ Buy your main residence
✅ Start your own business
⚠️ Attention These withdrawals are subject to strict conditions.
Note that each payment into your 3a entitles you to a tax reduction (within the annual limit).
The principle of taxes with your 3a
The imposition of 3a is based on a system progressive :
- The higher the amount withdrawn, the higher the tax rate.
For example if you remove 100,000 CHF in one go, You will pay more taxes than if you withdraw 50,000 CHF this year and 50,000 CHF the following year.
👉 For what ? Because taxes are calculated on the total amount withdrawn in one year.

Can I withdraw my 3a in several installments?
No, Swiss law requires you to remove the entire balance of a 3a account in one go.
But… There is a solution to save money when withdrawing 3a: having multiple accounts 3a and remove them from different years!
🎯 Tip: Stagger your 3a bills
For example, instead of concentrating 100,000 CHF in a single account, why not distribute them over 2 accounts of CHF 50,000 ?
📊 Concrete examples using the official Confederation calculator

Case 1: Withdrawal of CHF 100,000 in a single transaction
- Tax : 4,352 CHF (4.35 %)
Case 2: Withdrawal of 2 x CHF 50,000 over 2 years
- Tax : 1,570 CHF × 2 = 3,140 CHF (3.14 %)
➡ Savings: CHF 1,212 for the same total amount!
Note that you can use more than 2 accounts. Here is an example with 3 accounts.
Case 3: Withdrawal of CHF 1,000,000
- All at once : 85,701 CHF (8.57 %)
- In 2 installments (500,000 CHF × 2) : 39,804 CHF × 2 = 79,608 CHF (7.96 %)
➡ Savings: CHF 6,093 - In 3 installments (CHF 333,334 × 3) : 24,241 CHF × 3 = 72,723 CHF (7.27 %)
➡ Savings: CHF 12,978
👉 Conclusion : The more you spread out your payments, the less tax you pay!
How is it possible to pay less tax for the same amount?
The Swiss tax system applies a progressive rate on withdrawals from 3a.
- A high withdrawal = a high tax rate.
- Smaller withdrawals = lower rates.
💡 The staggered payment schedule allows you to "smooth out" your tax burden. and to pay less overall.
Okay, but is it legal to stagger your 3a?
Yes, at 100 %! But…

- Other cantons (like Vaud or Zurich) authorize it, but with specific rules.
⚠️ Absolutely check :
- The maximum number of 3a accounts allowed in your canton.
- The tax rate applied (it varies enormously from one canton to another!).
Example :
- Canton of Vaud : ~4.7 % of tax on 100,000 CHF.
- Canton of Schwyz : ~1.3 % on the same amount.
➡ You can pay up to 3 times more taxes depending on where you live!
How many 3a accounts can one have?
It depends only from your canton of residence :
- Some allow it only one account.
- Others allow it several
👉 Advice : Check with the tax administration of your canton before opening a new account.
Conclusion: What are the key takeaways?
1️⃣ The staggered payment plan (3a) allows you to significantly reduce your taxes (up to several thousand francs in savings).
2️⃣ Open multiple 3a accounts (if your canton allows it) and allocate your payments.
3️⃣ Remove each account from different years to take advantage of progressive taxation.
