How the €1,050 Tax Exemption on Savings Interest Works in 2025/2026
Belgium is often called the land of savers, but for an expat, the sheer number of tax rules surrounding a simple savings account can feel like a personal attack on your financial peace of mind. I still remember the cold sweat I broke into when I realized my home-country savings might be taxed at 30% here. This guide will walk you through exactly how the €1,050 tax exemption works so you do not lose your hard-earned interest to the Belgian taxman.
Understanding the Regulated Savings Account System in Belgium
To understand the €1,050 exemption, you first need to master the distinction between a regulated and a non-regulated savings account. In Belgium, the tax code is very protective of "regulated" accounts (compte d’épargne réglementé / gereglementeerde spaarrekening). These are accounts that follow specific Belgian legal requirements, such as offering both a base interest rate and a fidelity premium. Most traditional banks offer these as their standard savings products.
For the 2025 and 2026 tax years, the first €1,050 in interest earned on these regulated accounts is entirely tax-free. If you earn more than that, the bank automatically deducts a 15% withholding tax (précompte mobilier) on the amount exceeding the threshold. This is a significantly lower rate than the standard 30% applied to other forms of financial income. However, the catch is that this "automatic" system only works perfectly if you have all your money in a single bank.
The Definition of a Regulated Account
A regulated account must offer a base rate, which is earned daily on the balance, and a fidelity premium (prime de fidélité), which is earned only on money that stays in the account for 12 consecutive months. The Belgian government sets minimum and maximum limits for these rates to ensure they remain "safe" for the general public. Because of these strict rules, many international fintech platforms like Wise do not qualify as regulated accounts under Belgian law, meaning the interest they pay might be subject to different rules.
Why the €1,050 Threshold Matters
The threshold is indexed periodically to keep up with inflation. For several years, it sat at €980, but for the 2025/2026 period, it has been solidified at €1,050 per person. This is not just a "bonus" for the wealthy; it is a vital part of Taxes in Belgium for Expats: Personal Income Tax System 2026 designed to encourage residents to keep a liquidity buffer. For a single person, this means you could potentially have a significant amount of cash in a 2% or 3% interest-bearing account before ever paying a cent in tax.
Fidelity Premiums and the 12 Month Rule
Expats often make the mistake of moving money frequently between accounts to chase higher rates. In Belgium, this can be a costly mistake. The fidelity premium usually represents the larger portion of your interest. If you move your money before the 12-month "loyalty" period is up, you lose that premium entirely for that period. When calculating your total interest for the €1,050 exemption, both the base rate and the fidelity premium are added together.
How the Exemption is Applied in Real Life Scenarios
The most confusing part of this exemption is how it is calculated when your life does not fit into a neat little box. For most expats, banking is rarely simple. You might have a joint account with a partner, a separate account for your side hustle, and perhaps an old account from your first year in Brussels.
Married Couples and Legal Cohabitants
One of the biggest advantages of the Belgian system is that the exemption is per person, not per account. If you are married or in a legal cohabitation, your total exemption for a joint account is doubled to €2,100. This is a massive relief for families trying to save for a house down payment. However, the bank only applies this automatically if the account is officially registered in both names. If you simply share access to your spouse's account, the taxman will likely only see one exemption of €1,050.
The Multi-Bank Trap
This is where I personally got tripped up during my third year in Belgium. If you have €800 of interest at BNP Paribas and another €800 at KBC, neither bank will deduct the 15% tax because they both see you as being under the €1,050 limit. However, your total interest is €1,600. When you file your taxes via Tax-on-web (MyMinfin), you are legally required to declare the interest that exceeded the threshold across all banks. If you fail to do this, the tax authorities can see your total interest via the National Bank's records and hit you with a fine later.
| Account Type | Tax-Free Threshold (2025/26) | Tax Rate Above Threshold | Reporting Requirement |
|---|---|---|---|
| Regulated Belgian Savings | €1,050 per person | 15% | Automatic by bank (usually) |
| Joint Regulated (Couple) | €2,100 per couple | 15% | Automatic by bank |
| Non-Regulated / Foreign | €0 | 30% | Must declare in Tax-on-web |
| Term Accounts (Bons de caisse) | €0 | 30% | Automatic by bank |
Term Accounts and Other Financial Products
It is crucial to note that the €1,050 exemption does not apply to "Term Accounts" (comptes à terme) or "State Bonds" (bons d'état), unless a specific temporary law is passed for a particular issuance. Generally, interest from these products is taxed at the Tax on Investment Income: 30% Flat Rate on Dividends and Interest from the very first euro. Always check the "fiche technique" of a financial product before you sign up to ensure you know if it qualifies as a regulated savings account.
Non-Regulated Accounts and Foreign Savings
As an expat, you likely use neobanks or keep some savings in your home country. This is where the €1,050 exemption usually disappears. Most foreign accounts—whether they are in France, the UK, or the US—are considered "non-regulated" by the Belgian tax authorities. This means the interest is taxable at 30% from the first cent, and you do not get to use the €1,050 "coupon."
Using Wise, Trade Republic, and Binance
Platforms like Trade Republic have become incredibly popular because they offer high interest on uninvested cash. However, because these are German-regulated entities and do not necessarily offer the "fidelity premium" structure required by Belgian law, they are treated as non-regulated. You must manually declare the interest earned on these platforms. Similarly, any "staking" or "savings" rewards from Binance are generally treated as speculative income or standard interest, taxed at 30%, with no exemption applicable. While Wise is excellent for Sending Money In and Out of Belgium: Remittance and Currency, any interest-bearing "jars" you hold there must be scrutinized under the same non-regulated lens.
The Importance of Declaring Foreign Accounts
Belgium has very strict transparency laws. You are required to perform the act of Declaring Foreign Bank Accounts to the Belgian National Bank (NBB) for any account held outside of Belgium. Once the account is declared to the NBB, you then tick a box on your annual tax return. If you earn interest on these accounts, you must report the gross amount. The Belgian taxman will then calculate the 30% due. Note that if you already paid tax in the foreign country, you might be able to claim a credit depending on the double-taxation treaty, but the €1,050 exemption still will not apply.
Neobanks within Belgium
Some Online and Neobanks in Belgium: Keytrade, Argenta, and Revolut do offer regulated accounts. For example, Keytrade and MeDirect often have regulated savings products that look and feel like a modern app but still provide the tax-free €1,050 benefit. If you are looking to maximize your net return, it is often better to use a Belgian-regulated neobank for your cash savings than a foreign platform that pays a slightly higher gross rate but subjects you to a 30% tax with no exemption.
Strategies to Maximize Your Savings Interest
If you are a high-earner or have a significant "rainy day" fund, you need to be strategic. Simply dumping €200,000 into a single savings account is rarely the most tax-efficient move in Belgium, especially when you consider How the 50% Tax Bracket Works on Income Over €51,070 for your professional income. You want your money to work as hard as possible without triggering unnecessary 30% hits.
Splitting Assets Between Spouses
Since the exemption is individual, if one partner has a massive savings balance and the other has none, you are wasting €1,050 of tax-free space. Moving money to a joint account or a separate account in the other spouse's name can effectively save you €157.50 in taxes per year (15% of €1,050). It sounds small, but over a decade, that is a free weekend in the Ardennes.
The "Excess" Strategy
Once you are confident you will hit the €1,050 interest limit on your regulated accounts, any additional savings should be evaluated against other products. If your regulated account pays 2.5% (minus 15% tax on the excess), your net is 2.125%. If a Best Brokerage Accounts for Expats in Belgium (Bolero, Keytrade) product like a money market fund pays 3.8% but is taxed at 30%, your net is 2.66%. At high balances, the "non-regulated" high-interest products actually become more profitable even though they don't have the €1,050 exemption.
Monitoring the "Health Index"
The threshold of €1,050 is not static forever. The Belgian government adjusts these figures based on the health index. It is wise to check the latest circular from the FPS Finance every January. For 2026, there is a possibility this could rise again if inflation remains stubborn. Keeping an eye on these small administrative updates is the difference between being a "clueless tourist" expat and a "veteran" who knows how the system bends.
Timing Your Withdrawals
Because the fidelity premium is so central to the interest calculation, you should always check your bank's "premium simulator" before moving money. Most Belgian banking apps now have a tool that tells you: "If you move this €5,000 today, you will lose €45 in pending fidelity premiums." Wait until the day after the premium is "acquired" (usually the first day of the quarter following the 12-month anniversary) to move your funds. This ensures that the interest you do earn and apply toward your €1,050 exemption is the maximum possible.
Professional Advice and Final Checklist
Dealing with Belgian taxes can feel like death by a thousand papercuts. While the €1,050 exemption is a "gift" from the state, the penalties for miscalculation or failing to report foreign interest are stiff. If you have a complex international portfolio, it might be time to stop DIY-ing your finances.
When to See an Accountant
If your only income is a salary and you have one Belgian savings account, you don't need help. But if you are managing Freelancing and Self-Employment in Belgium: Legal Setup and Taxes alongside personal savings and foreign investments, an accountant is worth their weight in gold. They can ensure that you are correctly aggregating your interest from multiple banks so you don't get a "rectification" notice from the tax office three years down the line.
Your 2025/2026 Savings Checklist
- Identify which of your accounts are "Regulated" (look for the fidelity premium).
- For joint accounts, ensure both names are correctly registered at the commune and the bank to get the €2,100 limit.
- Total up your expected interest across all banks by December.
- If the total exceeds €1,050 (single) or €2,100 (couple), prepare to declare the excess in your next tax return.
- Ensure all foreign accounts (Wise, Trade Republic, etc.) are declared to the NBB.
- Calculate the 30% tax due on foreign interest, as the €1,050 exemption does not apply there.
