Thailand Tax
Calculator
See what Thailand actually pays you back. In five minutes, compare your home-country tax with Thai territorial tax, remittance rules, and real Bangkok lifestyle costs.
Run the
Thailand number.
A planning-grade estimate of what could land in your pocket after changing tax residency. Gross income, home country, remittances, family and living costs — all in one place.
Three inputs.
One clear number.
The calculator uses publicly available Thai Revenue Department brackets and broad home-country benchmarks. No personal data is stored until you choose to unlock your result.
Enter your income and country
Select your home country, income type (employed, freelance, or company owner), and annual gross. The calculator auto-sets the currency and pulls the right tax profile.
Set your Bangkok lifestyle
Enter your expected monthly spend in Thailand. This determines the remitted percentage — the slice of your income that is actually assessable under Thai PIT. Lower spend = lower Thai tax base.
See your personal number
The estimate shows your projected take-home in both scenarios, the annual upside, and a bar chart breaking down home tax, Thai tax, lifestyle cost, and retained income.
Why the numbers
look the way they do.
Thai tax residency is different from most European jurisdictions. Two rules drive almost all of the upside.
Territorial taxation
Thailand taxes residents only on income sourced in or remitted into Thailand. If your clients are in Berlin and you leave earnings in a European account, those earnings are not assessable. Most European countries tax worldwide income regardless of where it sits.
The remittance rule
Foreign income you transfer into Thailand in the same tax year you earn it is assessable. The calculator derives your remitted percentage from your monthly lifestyle spend. A €120k earner spending €1,500/month remits about 15% — Thai PIT applies only to that 15%.
Progressive PIT brackets
Thai personal income tax runs from 0% to 35%, but the effective rate on remitted income is almost always far below the headline rate — because only a fraction of income is remitted, and the first THB 150,000 of assessable income is tax-exempt.
Questions the
calculator can't answer.
The estimate handles the maths. These are the questions behind the numbers.
Is foreign income really tax-free in Thailand?
Not exactly tax-free — but close. Thailand taxes foreign-source income on a territorial basis: only income you remit (transfer) into Thailand in the same tax year you earn it is assessable. If you leave earnings abroad, they are not taxed. A 180-day resident who remits 30% of their income pays Thai PIT only on that 30%.
What changed in 2024 with Thailand's remittance rules?
Prior to 2024, foreign income earned in a previous tax year was never assessable, regardless of when it was remitted. Revenue Department guidance issued in late 2023 (effective 1 Jan 2024) extended assessability to income earned in the current year and remitted in the same year. Prior-year savings brought in later remain outside scope. The calculator uses the current rule.
What is the DTV visa and how does it affect my taxes?
The Destination Thailand Visa (DTV) is a five-year, multi-entry visa for remote workers with a minimum 180-day stay per entry. Holding the DTV does not automatically make you a Thai tax resident — that status is triggered by spending 180+ days in Thailand in a calendar year. Once tax-resident, the remittance rules apply.
How accurate is this calculator?
It is a planning-grade estimate, not a certified tax computation. Home-country tax uses broad progressive brackets and social-contribution averages by country and income type — not a full filing model. Thai tax uses the 2026 PIT brackets with a THB 60,000 personal allowance. Use it to understand the order of magnitude, then verify the specifics with a qualified adviser.
What does "remitted percentage" mean in the estimate?
Remitted income is the portion of your foreign earnings you transfer to Thailand. The calculator auto-derives this from your monthly lifestyle spend: if you earn €120,000 and spend €1,500/month in Thailand, you are remitting roughly 15% of your income. Only that 15% is assessable under Thai PIT.
Do I still owe tax in my home country after moving?
It depends on your home country's exit rules. Spain, Germany, and France have specific de-registration requirements and exit tax provisions. Some countries tax residents on worldwide income until formal tax deregistration. This calculator estimates only the Thai side — your home liability must be assessed separately, and CERØ can help you navigate the exit.
Does CERØ handle the visa and the tax residency together?
Yes. The CERØ service covers DTV visa application, Thai tax residency setup, home-country deregistration guidance, and ongoing compliance. The calculator gives you the numbers; the team handles the paperwork.
