A Belgian freelancer earning €120k pays approximately €63,700 in combined IPP (Impôt des personnes physiques), INASTI/RSVZ social contributions and a communal surcharge averaging about 7%. The same income, after declaring your departure at the commune (Modèle 8) and 180+ days of Thai tax residency under the DTV visa, pays about €3,600 in Thai PIT on the THB 95,000 a month brought in to live in Bangkok — roughly €60,200 of annual upside, fully legal under Thailand's remittance basis.

Thailand vs Belgium.
A Belgian freelancer earning €120k pays roughly €63,700 between IPP, INASTI social charges and communal surcharge. Belgium has one of the heaviest effective burdens in Europe. The Thai DTV swaps that for a five-year multiple-entry visa, remittance-basis tax, and around €60,200 of annual upside.
Effective tax on €120k ~€63,700
Annual upside ~€60,200
Exit form Modèle 8
In one sentence
The headline difference: Belgium taxes worldwide income on a steeply progressive IPP scale (25–50%, the 50% bracket starting at €51,070 in 2026) plus mandatory INASTI/RSVZ contributions for self-employed and a communal surcharge (0–9% of the income tax, about 7% on average). Thailand taxes a resident's foreign income only in the year it is brought into Thailand, on a Thai PIT scale starting at 0% with a 60,000 THB personal allowance.

02 · What the exit looks like
What the exit looks like.
The boxes that actually close your home tax file.
The Belgian exit has two steps. First, declare your departure at your commune by the day before you leave; it strikes you off its population register and hands you a Modèle 8 (Model 8 in Flanders) certificate, which you need to register with the Belgian embassy in Bangkok. Second, file your IPP/PB declaration for the year you leave, and tell your social insurance fund you are stopping self-employment. Since 1 January 2026 Belgium also has an exit tax: emigrating triggers 10% on gains built up since then on shares, funds and crypto, and departures that ended Belgian residence before 1 May 2026 fall outside the regime entirely. Payment is deferred automatically for Thailand, which is in Annex II of circular 2026/C/74 because articles 26 and 27 of the 1978 treaty provide information exchange and recovery assistance — an exchange of letters in 1991 nonetheless has the two states agreeing not to ask each other to collect, so the listing is one SPF Finances could revisit. The deferral holds while you neither sell nor pledge the assets and stay resident in a listed state, and the tax is cancelled after 24 months. Speculative deals stay taxable at 33% under Article 90, 1° CIR, and stock options under the 1999 law have their own timing. Belgium deems you resident while your home (for couples, the family home) stays there, or failing that the place your wealth is managed from, and staying on a commune register creates a presumption of residence — build the exit so the Modèle 8 matches reality.
03 · How daily life changes
How daily life changes.
Time zone, climate and cost of living vs Bangkok.
Bangkok runs 5 hours ahead of Brussels in summer and 6 in winter. Your afternoon meetings comfortably cover Belgium's morning. Bangkok's cool season runs about 21–33°C — a world away from Brussels' 2–6°C December. Cost of living drops materially: €650 for a one-bed in central Bangkok vs €1,000–1,400 in central Brussels; €300/month eating out daily vs €650+ in Brussels.
04 · Which one fits
Which one fits.
Honest framing: most Europeans go to Thailand. Here are the cases where they don't.
Stay in Belgium if…
- Your operating company and team are physically anchored in Belgium.
- You plan to sell significant financial assets soon after leaving, which the 2026 exit tax would catch.
- You depend on INASTI accruals or Belgian stock-option timing.
- Your family home stays in Belgium, which would keep you resident anyway.
Move to Thailand if…
- You're a remote freelancer or founder with international clients.
- You can spend 180+ days a year in Thailand to anchor tax residency.
- You want Thai tax only on the foreign income you bring in — fully legal, with a paper trail.
- You'd use the Thai tax-residency certificate to close your SPF Finances file.
05 · FAQ · Thailand vs Belgium
Questions people ask.
Real questions, real answers.
Is the Belgian effective rate really around 53% on €120k freelance?
Yes, when you stack IPP, INASTI/RSVZ (20.5% of net income up to €75,025, 14.16% up to €110,562, nothing above) and the communal surcharge (0–9% of the income tax, about 7% on average; many Walloon communes charge 8.8%, Brussels-City 4.9%). The CERØ Tax Calculator gives a real-time estimate using 2026 brackets.
Does Belgium have an exit tax?
Yes, since 1 January 2026: leaving triggers a 10% tax on gains built up since then on shares, funds and crypto, and stakes of 20% or more have their own scale. Departures that ended Belgian residence before 1 May 2026 are outside the regime. For Thailand, which Annex II of circular 2026/C/74 lists, payment is deferred automatically and needs no request; it holds while you neither sell nor pledge the assets and keep your residence in a listed state, and the tax lapses after 24 months. The annual attestation exists in the circular, but its content and deadlines are still to be set by royal decree. Speculative deals stay taxable at 33% under Article 90, 1° CIR, and stock options granted under the 1999 law have specific timing rules. Founders with substantial Belgian equity should model all three before moving.
How much can a Belgian freelancer earning €120k save by moving to Thailand?
About €60,200 a year, living on THB 95,000 a month in Bangkok. The figure moves with what you bring into Thailand, your commune's surcharge and your family situation; the Thailand tax calculator estimates it on your own numbers, using 2026 brackets.
Do I lose Belgian healthcare?
When you cease residency you exit the Belgian mutuelle / mutualiteit on the resident track. Most members switch to private health insurance — Thailand-only plans from about €60–120 a month, international plans for more — plus access to top Thai private hospitals (Bumrungrad, Bangkok Hospital, Samitivej).
Will SPF Finances challenge my Thai residency?
Only if the file is weak — a Belgian operating company still active, Belgian bank still receiving fees, family in Belgium, fewer than 180 days in Thailand. With Modèle 8 deregistration, a final IPP, a Thai tax-residency certificate, a Bangkok lease, and a clean break from your local company, the file holds. CERØ builds for that exact audit.
Is remote work done in Thailand taxed if the client or employer pays abroad?
It can be. Section 41 of the Revenue Code taxes income from work performed in Thailand whether it is paid inside or outside the country, and the Revenue Department's 2024 guide for foreigners gives work performed in Thailand as its example. The DTV carries no tax exemption, and no published Revenue Department ruling deals with remote work for foreign employers or clients. The figures on this page count only the foreign income you bring in, so treat them as the lower bound and confirm your position with a Thai tax adviser.
