BANGKOK, THAILAND – New Thai tax rules and an old German treaty have sharply changed how German pensions are taxed for retirees in the kingdom.
The three types of German retirement income
Many German retirees in Thailand faced a complex tax landscape that depended heavily on the type of pension they received. A 1967 German‑Thai double taxation agreement (DBA) strictly distinguished between three categories of retirement income, each with very different consequences for where tax was due.
Statutory pensions from the German Pension Insurance – including old‑age, reduced earning capacity and survivors’ benefits – were covered by Article 18(2) of the DBA. Under this rule, Thailand alone had the right to tax these payments, while Germany fully waived its claim to income tax on them.
For retirees who transferred their monthly statutory pension to Thailand, this meant liability to Thai income tax at progressive rates from 0% to 35%, depending on total income. Double taxation did not apply: they paid tax only in Thailand, not in Germany.
Occupational pensions and payments from pension funds or pension schemes fell under Article 18(1) of the treaty. Germany was allowed to tax these benefits only if the underlying pension had been deducted as a business expense in the profit calculation of a German company.
In practice, company pensions paid directly by a former employer and booked as a business expense remained taxable in Germany, even if the recipient lived in Thailand. By contrast, occupational pensions via external pension funds that were not recorded as business expenses were subject to Thai income tax.
Civil service pensions from federal, state or local authorities were treated as the most favourable exception. Article 19 of the DBA stipulated that pensions paid by a state or its bodies were exempt from tax in the country of residence.
For former German civil servants who moved to Thailand, this meant their government pension was not taxed in Thailand and was no longer taxed in Germany under the so‑called limited tax liability for non‑residents. The income still had to be declared in a Thai tax return, but remained fully tax‑free in both countries.
New remittance rules since 2024
From 1 January 2024, Thailand introduced new rules governing when foreign‑sourced income became taxable once brought into the country. These changes were crucial for retirees but still left room for planning for those who reacted quickly.
The core principle stated that anyone considered tax‑resident in Thailand – staying 180 days or more in the country in a calendar year – would be taxed in the year in which foreign pension payments flowed into Thailand. The year in which the pension was originally earned no longer determined the tax year.
Under this approach, a back payment from 2020 that was transferred to Thailand in December 2024 would be taxed in 2024. The timing of the transfer, rather than the accrual date, became decisive for Thai income tax.
A key exception, issued as Por.162/2566 in November 2023, protected all pension income generated before 1 January 2024. These funds remained tax‑free in Thailand, even if transferred there in 2024, 2025 or later, provided the retiree could document when the money had arisen.
Bank statements dated 31 December 2023 or official pension account statements served as crucial evidence of pre‑2024 balances. This allowed retirees with accumulated savings from earlier pension payments to move that money to Thailand without triggering income tax.
The exemption opened a practical strategy window: German retirees could now separate pre‑2024 reserves from pensions earned from 2024 onward. All new pension income generated from 2024 became taxable in Thailand as soon as it was remitted.
Example: statutory pensioner moving to Thailand
A concrete scenario illustrated how the system worked in everyday life. A 68‑year‑old former employee moved to Chiang Mai in 2024 and received 1,800 euros per month, around 67,500 baht, from the German statutory pension insurance.
On an annual basis, his pension amounted to about 810,000 baht. As a Thai tax resident staying more than 180 days in the country, he became liable for Thai income tax on this pension from 2024 onward.
Thai allowances significantly reduced his taxable base. A personal allowance of 60,000 baht and a flat 100,000‑baht deduction for work‑related expenses cut the taxable amount by 160,000 baht, leaving 650,000 baht.
Additional deductions depended on family situation and insurance. An unemployed spouse could be claimed for 60,000 baht, a child for 30,000 baht, and private health insurance premiums up to 25,000 baht. With a spouse and one child, the taxable income could fall to about 500,000 baht.
Applying Thailand’s progressive rates – 0% for the first 150,000 baht, 5% for the next 150,000 and 10% for the following bracket – the retiree’s annual tax bill would realistically be between 20,000 and 30,000 baht. This corresponded to less than 1% of his total pension, well below the average tax burden on pensioners in Germany.
When retirees are tax-resident in Thailand
Thai tax residency hinged on the 180‑day rule. Anyone spending 180 or more days in Thailand within a calendar year was treated as fully tax‑liable there, regardless of visa type or residence permits.
The authorities counted total days, not continuous stays. A pattern of January to June and October to December produced 181 days and thus full tax liability, while January to June and September amounted to roughly 153 days and remained below the threshold.
Some mobile retirees deliberately structured their travel to stay under 180 days in Thailand each year, legally avoiding Thai income tax on foreign pensions. This approach required careful record‑keeping using entry stamps and personal calendars.
Who pays what: three sample cases
One scenario concerned a former civil servant named Karl receiving a monthly government pension of 2,500 euros, about 93,750 baht. Under Article 19 of the DBA, this income was exempt from Thai taxation and could not be added to any other taxable base.
For Karl, the result was zero tax in Thailand on his civil service pension, regardless of other income sources. The arrangement represented the strongest tax advantage available to retired officials living in the kingdom.
A second scenario involved Maria, who received 1,200 euros per month – about 45,000 baht – from the statutory pension insurance plus 600 euros, around 22,500 baht, from an occupational pension fund. Her statutory pension fell under Article 18 and was taxable in Thailand.
The treatment of her occupational pension depended on whether it had been booked as a business expense in Germany. If it had, Germany retained taxing rights; if not, the income was taxable in Thailand. In such cases, professional advice from a tax specialist was essential.
A third example highlighted the value of pre‑2024 reserves. Werner had around 600,000 baht, roughly 16,000 euros, in unused pension savings on his German account at the end of 2023.
Under the Por.162/2566 exemption, he could transfer this amount to Thailand tax‑free in 2024, 2025 or 2026 as long as he could document its origin before 2024. All subsequent pension transfers, however, became taxable when remitted.
Key checks before moving to Thailand
Retirees planning a move were advised to clarify which type of pension they received before changing residence. Statutory pensions were generally taxed in Thailand, many occupational pensions potentially remained taxable in Germany, and civil service pensions enjoyed a complete exemption.
Obtaining a bank statement dated 31 December 2023 helped prove how much pension income had accrued before 2024. This documentation was critical to ring‑fence pre‑2024 savings that could later be brought into Thailand without tax.
Prospective migrants also had to decide whether to stay above or below the 180‑day threshold each year. This decision directly determined whether they became fully taxable on foreign income in Thailand.
Ahead of the move, retirees were encouraged to make full use of available allowances, such as deductions for a non‑earning spouse, children and private health insurance. These measures could noticeably reduce the effective tax burden.
Engaging a German‑speaking tax adviser in Thailand was presented not as a luxury but as a necessary investment. A certificate from the German tax authority confirming treaty treatment of the pension could further help Thai officials understand where the primary taxing rights lay.
Orientation, not individual advice
The guidance on German pensions in Thailand showed that the system was complex but manageable with accurate information. Understanding the exact pension type, the impact of the 1967 DBA, and the 2024 remittance rules formed the basis for legal tax optimisation.
Using the transition rule for pre‑2024 funds and seeking expert advice from professionals familiar with both tax systems could improve planning security. For many retirees, this preparation translated into lower tax payments and clearer compliance.
The scenarios and figures were based on current treaty provisions and Thai tax law for the years 2024 to 2026. Currency conversions, using an exchange rate of roughly 1 euro to 37.50 baht in February 2026, were approximate and subject to market changes.
Readers were reminded that the information offered general orientation on German‑Thai tax issues. Binding assessments and individual strategies required consultation with certified tax advisers or lawyers in both Germany and Thailand.
