Investing your surplus savings in 2026: pension savings and buy-to-let property

The standard wealth-building order for a self-employed person in Belgium in 2026: (1) a safety buffer of 3-6 months of expenses in a regulated savings account; (2) PLCI/VAPZ up to the 2026 ceiling (€4,086.34 standard or €4,701.54 social): the best tax leverage; (3) IPC/POZ within the 80% rule, depending on your status; (4) third-pillar pension savings (€1,050 or €1,350); (5) buy-to-let property or a securities portfolio.

The trade-off between property and securities depends on your horizon, borrowing capacity and appetite for managing rentals.

The third pillar (individual tax-advantaged pension savings) allows anyone resident in Belgium for tax purposes, self-employed or employed, to pay up to €1,050 (30% tax reduction) or €1,350 (25% reduction) a year into a pension savings fund or savings insurance, and benefit from a federal tax reduction. It can be freely combined with the PLCI/VAPZ, the IPC and the POZ/CPTI.

In your own name, rental income is taxed under personal income tax on the basis of the indexed cadastral income plus 40% (letting to a private individual) or on the actual rent (letting to a business). There is no withholding tax on movable income on the rent, but no deduction of actual expenses in the first case.

Through an SRL/BV, actual rents are company income (corporate income tax at 20% for SMEs or 25%), with full deduction of mortgage interest, depreciation (typically over 33 years), works and fees. Getting the property out (sale or liquidation) remains heavily taxed. The choice depends on the size of your assets, the leverage you want and your plans for passing them on.

As a guide, a well-located flat in Brussels typically generates a gross return of 3.5% to 5% and a net return after charges, tax and vacancies of 2% to 3.5% (Statbel / FPS Economy 2025). A dynamic pension savings fund has historically delivered 4 to 6% gross over 20 years (FSMA). Over a 25-year horizon, mortgage leverage plus the capital gain on sale often tips the balance towards property, at the cost of active management and concentration risk.

The sale of a property held in your own name is exempt from capital gains tax if it takes place more than 5 years after purchase (main residence always exempt, investment property after 5 years).

Before 5 years: the capital gain is taxed at 16.5% (undeveloped land) or 33% (built property other than the main residence). If held through an SRL/BV, the capital gain on sale goes into the taxable corporate profit (20% for SMEs or 25%). Source: FPS Finance 2026, Income Tax Code Art. 90-91.

An annual payment of €1,050 for 30 years, compounded at an average net 4%, builds up around €61,000 in capital (before the final 8% tax at 60, i.e. ~€56,000 net). At 6% net, the capital rises to ~€85,000. The 30% tax reduction recovered each year (€315) brings the net annual cost down to €735. Net leverage: ~2.1× at a 4% return.

Yes. The PLCI/VAPZ is excluded from the 80% rule, so it can be combined with an IPC/POZ within the combined ceiling. Third-pillar pension savings (€1,050 or €1,350) are completely independent: they do not count towards the 80% rule and can be combined with every other scheme. That is why they remain a worthwhile extra even for a self-employed person who has already maxed out their second pillar.

Buying through an SRL/BV becomes worthwhile with a significant property portfolio (≥2 properties, or 1 high-yield property) and a long-term aim. Advantages: full deduction of interest, accounting depreciation, corporate income tax at 20% for SMEs, lower than the 50% marginal personal income tax rate.

Drawbacks: double taxation (corporate tax, then personal income tax on dividends), benefit in kind for private use, heavily taxed capital gain on sale, a management structure to maintain. To be costed by a tax adviser; for guidance only.

It is legally possible but rarely advisable. Besides losing the capital gains exemption on sale (5 years as an individual), private use of a property owned by the company generates a benefit in kind (BIK) taxable under personal income tax. The regional home-ownership tax bonus (Wallonia-Brussels-Flanders) is not available to an SRL/BV. As a rule, your main residence is held in your own name.

Belgian tax-advantaged pension savings (third pillar) are regulated: only pension savings funds approved by the FSMA can receive payments eligible for the tax reduction. In practice these are managed funds, with typical management fees of 1-1.5%. To invest in ETFs with tax optimisation, you have to step outside the third-pillar framework (an ordinary securities account, with no annual tax advantage but lower fees).
