Foreign Brokerage + Belgian Tax Calculator = Big Savings!
Are you a Belgian investor tired of paying sky-high transaction fees at your local bank?
You're not alone!
Every year, thousands of Belgian investors lose hundreds, and in most cases even THOUSANDS of euros to excessive fees at traditional Belgian banks.
More expensive per trade at Belgian banks
Foreign brokers don't handle your Belgian taxes
Low broker fees + hassle-free tax compliance
That's where Belgian Tax Calculator comes in. Upload your broker statements and we calculate everything: your TOB due, your dividend tax obligations, your capital gains, and exactly what to declare on your tax return. No spreadsheets. No confusion. No mistakes.
The Real Cost of Belgian Banks
Buying €1,000 of IWDA? Keytrade charges €5.95. Bolero charges €5-7.50. The same trade at Interactive Brokers? About €1.25. At Trade Republic? Just €1.
US stocks are even worse: Keytrade charges up to $29.95 per trade. Bolero charges $15+. Interactive Brokers? About $1.
If you invest monthly, these fees compound into serious money over time. An investor making 12 trades per year could easily save €200-500 annually just by switching brokers.

What "Self-Declare" Actually Means
When a broker doesn't handle Belgian taxes, you're responsible for:
- Know which tax rate to apply
- Calculate 0.12% to 1.32% on every buy AND sell
- File and pay by end of the 2nd month after transaction
- Late? You will need to pay fines.
- Account for foreign dividend withholding tax
- Calculate 30% Belgian tax on net dividends
- Track the annual exemption
- Report on tax return (codes 1437/2437 or 1444/2444)
- Calculate avg cost by weighted average prior to 01 January 2026
- Track cost basis for every position using FIFO
- Apply the 31/12/2025 snapshot rule for older holdings
- Calculate gains, apply exemption, calculate total capital gains tax
Sound complicated? It is. That's exactly why we built Belgian Tax Calculator.
