Savings taxation in Belgium 2026: withholding tax, exemptions and filing
The advertised return is never the return you receive. Between a regulated savings account, a term account and a share dividend, tax treatment varies by a factor of two — for the same euro of income. And two perfectly legal exemptions are lost every year by hundreds of thousands of Belgians, for want of one box ticked.

🇧🇪 All of Belgium
Income from savings and investments — interest and dividends — is investment income. It bears a withholding tax that the Belgian bank deducts at source and pays over to the tax authority. Once that tax has been withheld, it is final: nothing to declare, nothing to add.
All the nuance lies in the exceptions — and there are many.
The 2026 rates, in one table
| Type of income |
Rate |
Exemption |
| Interest on a regulated savings account | 15% | First €1,020 per taxpayer |
| Interest on a term account, savings certificate, bond | 30% | None |
| Dividends on shares | 30% | First €833, reclaimable through the tax return |
| Interest from approved crowdfunding | 30% | Up to €16,270, under strict conditions |
| Interest from approved social enterprises | 30% | €200 |
The gap nobody calculates
€100 of interest: €100 net on a savings account below the threshold, €85 above it, €70 on a term account.
The regulated savings account: the only product with a real exemption
This is the most favourable regime in the Belgian system, and it hinges on a precise legal status: the account must be regulated, meaning it complies with the statutory remuneration conditions — a base rate plus a loyalty premium earned after twelve months.
🎯
€1,020 per person, all accounts combined
The exemption is assessed per taxpayer, not per account or per bank. Opening five savings accounts does not multiply the exemption by five: the total interest across all regulated accounts is compared with the same €1,020 ceiling.
👫
€2,040 for a couple — provided you split it properly
Each spouse or legal cohabitant has their own ceiling. Concentrating all savings in one name loses the household half its exemption. For married couples under the statutory regime, interest and dividends are in any case split 50/50 in the return, whoever holds the account.
🧊
A frozen ceiling that keeps losing value
The €1,020 figure is no longer indexed. With savings rates back up, the threshold is reached faster than before: at a 2% return, roughly €51,000 is enough to cross it and start paying 15%.
🏦
The bank already withholds, if you go over
Your bank knows the interest it paid you and applies the tax to the part exceeding €1,020 with them. If you hold accounts at several banks and the total exceeds the ceiling, you must declare the untaxed part. That is your responsibility, not the banks'.
💡 Savings account or government bond?
The comparison is not made on the gross rate. A government bond at 2.50% gross returns 1.75% net after 30% withholding tax. A savings account at 2% whose interest stays below €1,020 returns… 2% net. Our page on Belgian government bonds 2026 does the full calculation, and our ETF guide covers equity investments.
The €833 of dividends: the money asleep in your tax return
This is probably the worst-used exemption in Belgian taxation, because it works the opposite way round from every other one: the tax is withheld first, then refunded on request.
1
The bank withholds 30% at source
On a dividend of €833 it withholds €250, whatever your situation.
2
You report the dividends in your return
In the box for withholding tax deducted on ordinary dividends, you state the amount on which you claim the exemption.
3
The tax authority refunds the corresponding tax
Up to about €250 per taxpayer per year, so €500 for a couple. Nothing to ask the bank: it all happens in the return.
⚠️ Unclaimed is lost. The exemption is never granted automatically. It applies only to dividends — not to bond interest or to distributions from most funds — and you must keep the contract notes proving the tax withheld. If you hold individual shares or distributing ETFs, this is the most profitable annual reflex in your tax return.
The taxes that do not depend on your return
Beyond withholding tax, two levies hit the assets themselves, regardless of any gain.
📈 Tax on stock exchange transactions (TOB)
On every purchase and every sale
•
Due on secondary-market transactions, on purchase
and on sale.
•
The rate depends on the type of instrument — shares, bonds, accumulating funds — and a cap applies per transaction.
•
A Belgian broker withholds and pays it. With a foreign broker without an arrangement, you must declare and pay it yourself.
🏛️ Annual tax on securities accounts
On large portfolios
•
Applies to securities accounts whose average value exceeds €1,000,000.
•
It targets the amount held, not the return: it is due even in a loss-making year.
•
Avoidance schemes — splitting accounts just before the reference date — are expressly targeted by an anti-abuse provision.
Since 2026 the capital gains tax on financial assets sits alongside these, with its own annual exemption. It has its own page: capital gains tax 2026. Do not confuse it with withholding tax: they are two distinct taxes that can hit the same portfolio.
Savings abroad and non-Belgian brokers
Opening an account with a foreign bank or using an online broker established outside Belgium is perfectly legal. It simply shifts the obligations onto you.
📝
Declare the income
No Belgian tax was withheld: foreign interest and dividends must be reported in your personal income tax return. They are taxed there at the same 30% rate.
🏦
Report the existence of the account
A double obligation: a box in the tax return, and a notification to the Central Point of Contact at the National Bank of Belgium.
🌐
Do not count on discretion
Automatic exchange of information between European tax administrations makes detection of an omission close to certain, with tax increases and fines to follow.
💸
Double taxation of foreign dividends
A dividend from a foreign company first bears the source country's withholding, then 30% Belgian tax on the balance. Double tax treaties sometimes allow part of the foreign withholding to be recovered, at the cost of an often heavy procedure. One more argument for accumulating ETFs, which distribute nothing.
Optimising without doing anything illegal
1
Split savings between both members of the couple
Two ceilings of €1,020 beat one. It is free, immediate, and takes a single transfer.
2
Claim the €833 of dividends every year
One line in the return, up to €250 recovered per person. Set a reminder for tax return season.
3
Do not leave more than your safety buffer sitting idle
Three to six months of expenses in a savings account is a cushion. Beyond that, inflation costs more than the tax: that is the reasoning developed in saving while renting and investing beyond property.
4
Use the tax-advantaged envelopes first
Pension savings gives a tax reduction on the way in that no free investment offers. It logically comes before the securities account.
Common pitfalls
🔢
Multiplying accounts hoping to multiply the exemption
The ceiling is per person, not per account. Ten accounts do not exempt €10,200.
🎣
Chasing promotional rates without reading the structure
A regulated account pays a base rate plus a loyalty premium earned only after twelve months. Hopping between banks every six months systematically forfeits the premium — often half the advertised return.
📄
Forgetting to declare income not taxed at source
Foreign accounts, interest between private individuals, income paid without a Belgian intermediary: no tax was withheld, so declaring is mandatory.
⚖️
Confusing withholding tax with capital gains tax
The first hits income paid out — interest, dividends. The second hits the gain realised on sale. One portfolio can bear both.
