BANGKOK, Thailand – Many retirees living in Thailand from Germany, Austria, and Switzerland wrongly believe they do not have to pay taxes there, often misinterpreting declaration obligations as payment duties.
This guide aims to clarify when tax declaration becomes mandatory, when taxes are actually due, available tax allowances for retirees, and why many should still file a declaration even if no payment is owed.
Wer in Thailand steuerpflichtig ist
An individual is considered a tax resident in Thailand if they stay in the country for at least 180 days within a calendar year, not necessarily consecutively. This typically applies to most long-term residents with retirement visas. The basis for this is Section 41 of the Thai Revenue Code, further defined by Ministerial Regulations Por. 161/2566 and Por. 162/2566, effective from January 1, 2024.
Taxable income includes foreign earnings that are transferred to Thailand within the same calendar year they were earned. For instance, money earned in 2023 but sent to Thailand in 2025 is not taxed under the current interpretation. Income earned and transferred in 2025 must be declared for that year. A worldwide income principle has not been implemented as of June 2026.
Erklärungspflicht und Steuerpflicht sind nicht dasselbe
An obligation to file a tax return begins for individuals with a gross income exceeding 120,000 Baht annually, and for couples above 220,000 Baht. Those exceeding these thresholds must submit a declaration, even if no tax is due after all deductions. This is a common misconception: the declaration is still required.
The deadline for filing is March 31 of the following year, with an online extension until April 8. Actual tax liability starts only when taxable income exceeds 150,000 Baht after all deductions. Income below this threshold incurs no tax. Progressive tax rates apply from 5 percent up to 35 percent for incomes exceeding 5 million Baht.
Freibeträge für Rentner: Was absetzbar ist
Thailand offers several tax allowances that can accumulate for older expats. A flat deduction for work-related expenses is 50 percent of income, capped at 100,000 Baht. Additionally, there is a personal allowance of 60,000 Baht.
Individuals aged 65 or older receive an age allowance of 190,000 Baht. Married individuals can claim an additional 60,000 Baht for their spouse. Combined, this can create a tax-free buffer of up to 560,000 Baht for a married retiree over 65 before any tax is levied.
Was das DBA für DACH-Rentner ändert
The Double Taxation Agreement (DTA) between Germany and Thailand determines which country has taxing rights. German statutory pensions are covered under Article 18, with Thailand having the taxing right and Germany not withholding taxes at source.
Under Article 17, German civil servant pensions are taxed by Germany, not Thailand. Austrian retirees may face withholding tax in Austria, which can be reclaimed by confirming with the Thai tax authorities. Swiss retirees with private pension funds are only taxed in Thailand, while those with public funds may have withholding tax in Switzerland that can be credited in Thailand.
Ein konkretes Rechenbeispiel
A married retiree, aged 68, transfers approximately 800,000 Baht to Thailand in 2025. After deductions for work expenses (100,000 Baht), personal allowance (60,000 Baht), age allowance (190,000 Baht), and spouse allowance (60,000 Baht), 390,000 Baht remain.
The first 150,000 Baht are tax-free. The remaining 240,000 Baht are taxed at 5 percent, resulting in 12,000 Baht, approximately 325 Euros annually. Retirees transferring less or utilizing savings from previous years can significantly lower this amount.
Was Rentner jetzt konkret tun sollten
Those who transferred more than 120,000 Baht in gross income to Thailand in 2025 should check if a tax declaration is required, regardless of whether tax is ultimately payable. The tax form, PND 90, is submitted to the Revenue Department, with online filing available at rd.go.th.
For first-time filers or those uncertain about declaring DTA income, consulting a locally accredited tax advisor is recommended. Structuring transfers to avoid tax by sending funds in a subsequent year is legally debatable and may be viewed differently by tax authorities.
Zinseinkünfte und Mieteinnahmen in Thailand
Interest income from Thai bank accounts is subject to a 15 percent withholding tax, automatically deducted by the bank. This is not income tax for PND 90 but should be considered. Rental income from Thai properties must be declared, even if the property is in a Thai partner’s name, as economic benefit is key.
Foreign rental income, such as from a German apartment, is only taxable in Thailand if the amount is transferred within the same year. Delaying transfers to the following year may mean no taxable event in Thailand under current regulations, though this interpretation is debated among tax professionals.
LTR-Visum: Die einzige Kategorie mit echter Steuerbefreiung
The Long Term Resident (LTR) Visa under the Wealthy Pensioner category offers the only official exemption from Thai income tax on foreign remittances, irrespective of the transfer year. Requirements include a proven annual income of at least 80,000 US dollars or 40,000 dollars plus a 250,000-dollar investment, and health insurance coverage of at least 50,000 dollars.
The Thailand Privilege Visa does not offer this tax exemption. Individuals residing in Thailand for over 180 days with a Privilege Visa are considered tax residents subject to standard rules. This is a common misunderstanding on expat forums; the Privilege Visa grants residency rights, not tax benefits.
Steuerberater in Thailand: Wann man einen braucht
Retirees receiving only statutory pensions from Germany and transferring less than 560,000 Baht annually may not need a tax advisor. However, those with multiple income sources—pensions, rental income, capital gains, or occupational pensions—should consult a locally accredited tax advisor once to clarify their situation.
Initial consultations with tax advisors in Thailand typically range from 3,000 to 8,000 Baht. The Revenue Department’s online portal (rd.go.th) is available in English but has a learning curve. Seeking professional guidance for the first filing can prevent back payments or penalties for incorrect declarations.
