Retiring in Belgium
Belgium: the tax picture for FIRE
Belgium's income tax starts early and climbs fast: after a €10,910 tax-free allowance, bands of 25%, 40% and 45% give way to a 50% top rate from €49,840 of taxable income — before the roughly 7% municipal surcharge, which Ember does not model. From 1 January 2026 a new flat 10% capital-gains tax applies to financial assets, above a €10,000 annual exemption. For UK pensions, the treaty is modelled as residence-based: pensions from after 1 January 2013 are taxed only in Belgium, while pre-2013 non-state pensions remain taxed in the UK.
At death Belgium taxes the recipient, not the estate, and each of its three regions runs a completely different scale keyed to the deceased's last main residence; Ember encodes Flanders, covering roughly 58% of the population. Spouses are not wholly exempt anywhere, though the family home passes tax-free to a surviving partner in all three regions (not modelled). Ember applies an illustrative cost-of-living factor of 0.97, held at low confidence. Overall coverage is medium-confidence: municipal surcharges, the savings-interest exemption and Flanders' split movable/immovable inheritance calculation are approximated or unmodelled.

What this model doesn’t capture (6)
- municipal surcharge (~7%) not modelled
- tax-free sum modelled as a 25% tax credit (belastingvermindering) — matches the reduction method
- savings-income exemption (€1,020 interest exemption) not modelled
- dividends/interest: Belgium's flat 30% roerende voorheffing (final withholding for most residents; only the first €833 of dividends per person per year is reclaimable via the return, 2026) is not modelled — dividends here fall through to the ordinary income schedule instead
- capital gains tax on financial assets (NEW, in force 1 Jan 2026): Belgium's 10% flat levy ('solidarity contribution') on realised gains on shares/bonds/ETFs/crypto/gold — ~€10,000 indexed annual exemption (unused portion carried forward €1,000/yr, cap €15,000), cost basis = 31 Dec 2025 portfolio snapshot so only post-2025 appreciation is taxed — is NOT modelled; the pack computes zero CGT, which UNDER-states tax for a retiree realising portfolio gains (triage 2026-07-22)
- selfEmployment: no regime module — self-employed social contributions / business-income surcharges for this jurisdiction are not modelled
Capital gainsmedium confidence
Capital gains are taxed at a flat 10% above an annual exemption of €10,000.
NEW 10% CGT on financial assets from 1 Jan 2026 (in force; €10k annual exemption).
Inheritance & estate taxmedium confidence
Tax is charged on each recipient, scaled by their relationship to the deceased.
Recipient-side regional inheritance tax (erfbelasting/droits de succession) — Belgium has THREE completely different regional scales keyed to the deceased's last main residence (≥2.5 of last 5 years). This pack encodes FLANDERS (covers ~58% of the population and the modal Belgian expat/FIRE user); Wallonia and Brussels differ materially (recorded in gaps). Spouses are NOT wholly exempt anywhere in Belgium, but the family home passes 100% tax-free to the surviving partner in all three regions (unmodelled; Flemish de facto cohabitants need ≥3 years' cohabitation for the home exemption, vs ≥1 year for partner tariff status), and the partner's €75,000 allowance legally covers net MOVABLES only — here applied to the whole share. The shifted partner bands reproduce the legal foot-relief mechanics (remainder does not restart at 3%). Biggest distortion: Flanders runs the direct-line/partner scale SEPARATELY over the movable and immovable portions of each heir's share (each from 0%), so this single-run encoding OVER-taxes mixed estates (a €200k half-movable/half-immovable child share really pays €12,000, not the €15,000 computed here); 'other' conversely UNDER-taxes multi-heir cases (group aggregation).
When should you claim your Belgium state pension?medium confidence
Belgium statutory pension (pension légale / rustpensioen)
Normal pension age 66. There is no actuarial claiming-age lever — the amount doesn't change with when you claim.
No claiming-age lever in 2026 — a genuine gap year: the old pension bonus was abolished as of 1 Jan 2026 (last accrual 1 Jul 2024 – 31 Dec 2025) and the new birth-cohort bonus/malus regime (2%/4%/5% per year by birth cohort) only starts 1 Jan 2027, so this row needs re-review before 2027. Normal age is 66 for pensions starting 1 Feb 2025 – 31 Jan 2030, rising to 67 from 1 Feb 2030 (not modelled). Early claiming exists (63 with a 42-year career, 61/43, 60/44) but is contribution-history-dependent and simplified out per the FR/ES precedent. Worldwide inflation-indexation of payments abroad is assumed (no UK-style freeze) but was not verified against a primary SFPD source for non-EU/UAE residence.
The best age to claim isn’t just about these factors — it depends on your life expectancy, your other income, and which country you’re tax-resident in when the money lands. Deferring into a lower-tax country can flip the answer entirely. Optimise your claim age →

UK private pension
Under the UK treaty, a UK-sourced private pension paid to a resident here is generally taxed only where you live (not by the UK).
Common questions
How are capital gains taxed in Belgium?
From 1 January 2026, Belgium levies a flat 10% tax on gains from financial assets above an annual exemption of €10,000. The rate is the same regardless of your income level, and the regime is already in force. It is a new tax, and Ember models it at medium confidence.
Will my UK pension be taxed in Belgium?
Under the UK–Belgium treaty as modelled, pensions from after 1 January 2013 are taxed only where you live — so as a Belgian resident they fall into Belgium's income bands, from 25% up to 50% above €49,840, after a €10,910 tax-free allowance. Non-state pensions from before 2013 are grandfathered and stay taxed in the UK. Note that the roughly 7% municipal surcharge on top of income tax is not modelled.
Is there inheritance tax in Belgium?
Yes — Belgium taxes the recipient, at rates depending on their relationship to the deceased, and each of the three regions applies a completely different scale keyed to where the deceased mainly lived in their last five years. Ember encodes the Flanders scales, which cover roughly 58% of the population; Wallonia and Brussels differ materially. Spouses are not wholly exempt anywhere, though the family home passes tax-free to a surviving partner in all three regions (not modelled). Because Flanders taxes movable and immovable assets on separate scales, Ember's single-scale encoding can over-tax mixed estates.
