Frequently Asked Questions

Why is tax based on deemed returns instead of actual returns?

The deemed return system simplifies tax calculation and prevents tax avoidance through low-yield investments. However, it can result in tax liability even when investments lose money.

What counts as savings vs investments for Box 3?

Savings include bank accounts, savings accounts, and cash. Investments include stocks, bonds, mutual funds, ETFs, and other securities. Different deemed return rates apply to each.

Can I deduct all my debts from my wealth?

Only debts above €3,800 threshold can be deducted. This includes mortgages on investment properties, investment loans, and other qualifying debts. Personal loans and credit cards may not qualify.

How do couples handle Box 3 taxation?

Each partner gets their own €57,684 exemption. Couples can optimize by allocating assets between partners, but there are rules about attribution of jointly-held assets.
