Taxes in Thailand for Germans 2026: remittance, DTA, 180 days

Taxes for Germans in Thailand: DTA, Residency Cancellation and What Really Matters

I often see Germans who move to Thailand thinking: "I deregister in Germany, then I'm tax-free." Unfortunately, it's not that simple. Tax liability depends on several factors, and the Double Taxation Agreement (DTA) between Germany and Thailand only determines which country can tax which income. If you don't understand this, you can face nasty surprises – from the German tax office or the Thai Revenue Department.

The 7 Points (Quick Overview)

1. Cancelling German residency — properly deregister, not just on paper 2. The 183-day rule — decides whether Thailand can tax you at all 3. Pensions under the DTA — statutory pension stays taxable in Germany 4. Transfers to Thailand are taxable — once the money arrives, not before 5. Filing obligation in Thailand — tax resident status kicks in after 180 days 6. Credit instead of double payment — the DTA avoids double taxation, but not automatically 7. Advisors on both ends — Thailand and Germany, not just one

Cancelling Residency in Germany: The First Step, But Not the Last

When you deregister your residence in Germany, you generally lose unlimited tax liability there. That means you no longer have to pay tax on your worldwide income in Germany. But beware: The tax office checks carefully whether you still have your center of life in Germany. If you keep an apartment, stay in Germany for more than six months a year, or have close family ties, the tax office may still assume a domestic residence. I advise my clients: Deregister properly, sell or rent out your property, and limit your stays in Germany to a maximum of 180 days per year. Otherwise, unlimited tax liability may apply – and the tax office can demand back payments even years later.

The Double Taxation Agreement (DTA) Thailand – Germany: Who Taxes What?

The DTA between Thailand and Germany is a classic. It assigns certain types of income to one country or the other. The basic rule: Income from employment (salary) is taxed in the country where the work is actually performed. So if you work for a German employer from Thailand, Thailand can tax it – but only if you stay in Thailand for more than 183 days a year. In practice, many Germans working remotely for German companies pay no tax in Thailand on their salary because they don't meet the 183-day rule. But caution: The Thai Revenue Department may still assume tax liability if you actually stay more than 180 days a year. The interpretation is not always clear.

Pensions from Germany: The DTA also applies here. Statutory pensions are taxed in Germany, not in Thailand. Private pensions or company pensions may be treated differently depending on the contract. I recommend: Have your pension payments checked by a professional before moving to Thailand. Otherwise, you may pay double tax or have to file tax returns in Thailand retroactively.

Tax Liability in Thailand: What You Need to Know

Thailand taxes income earned in the country or brought into the country. That sounds simple but is complicated. If you live in Thailand and have income from abroad (e.g., rental income from Germany), you may need to tax it in Thailand as soon as you transfer the money to Thailand. Thai tax law is progressive: Up to a certain allowance (approx. 150,000 Baht per year, as of 2025), you pay no tax. Above that, rates go up to 35%. However, there are many deductions and allowances, e.g., for children, insurance, or pension provisions. I advise: Keep a bank account in Thailand and transfer only what you need; leave larger amounts in Germany or in an offshore account. But caution: The Thai Revenue Department is tightening controls on foreign income. Since 2024, there are new reporting requirements for banks. The topic is evolving.

Tax Filing in Thailand: Obligation or Option?

Many Germans in Thailand don't file a tax return because they think they have no income in Thailand. That can be a mistake. If you live in Thailand for more than 180 days a year, you are considered a tax resident. Then you may need to declare all income you transfer to Thailand in your tax return. The Thai tax office can also check bank transactions during an audit. I've seen cases where Germans had to pay back taxes after years because they didn't file. My tip: Get advice from a Thai tax accountant (preferably English-speaking). The cost is manageable (approx. 5,000–10,000 Baht per year), and you'll sleep better.

Avoiding Double Taxation: Credit or Exemption

The DTA provides for avoidance of double taxation – either by exemption (income is taxed only in one country) or by credit (tax paid abroad is credited against domestic tax). In practice, this means: If you pay tax in Thailand on your rental income, you may be able to have it credited in Germany if Germany still has the right to tax. But that's bureaucratic. I recommend: Avoid having to tax income in both countries by cleanly separating your income sources. Consult a German tax advisor with Thailand experience – it's worth the money.

Conclusion: Taxes Are No Reason to Panic, But No Walk in the Park Either

The tax question when moving to Thailand is complex but not unsolvable. If you cleanly cancel your residence in Germany, understand the DTA rules, and file a proper tax return in Thailand, you usually have nothing to fear. But I advise everyone: Get professional advice – from a German tax advisor for foreign matters and from a Thai tax advisor on the ground. I'm not a tax advisor; I can only report from practice. Invest a few hundred euros in advice before you move. It will save you thousands in back taxes and hassle with two tax authorities later.

If you're planning to move to Thailand, I'm happy to give you an honest assessment before you take the first step.

Frequently asked questions

When do I become tax resident in Thailand? As in the seven points above: spending 180 days in a calendar year in Thailand generally makes you tax resident there. That is a rule of thumb, not individual advice.

What does remittance mean since 2024? Foreign-source income becomes taxable once you transfer it into Thailand — not merely because it arose abroad. See point 4.

Does German statutory pension stay taxable in Germany? According to the DTA section in this article: statutory pension remains taxable in Germany. Other income can sit elsewhere. Clarify with advisers in both countries before you deregister.

Is one adviser in one country enough? No. Point 7: advisers on the ground and in Germany, both sides.
