ThaiESG — the last year of the enhanced deduction

Is there anything on a fixed deadline worth acting on?

Invest now Stage purchases rather than investing everything at once

If you are eligible and can accept five years of Thai-market risk, calculate the ThaiESG allowance before 31 December 2026: up to ฿300,000, subject to the 30% income cap.

The job Own Thailand

Earns in the currency you spend. Removes exchange-rate risk from the part of your money that will pay Thai bills.

The argument

The rule is legal rather than predictive: a qualifying purchase can reduce taxable income. The baht benefit is not simply the purchase amount times one tax rate; it depends on assessable income, progressive brackets, other allowances and full compliance. Market losses and fees can exceed the tax benefit.

Ministerial Regulation No. 395 and the Revenue Department's filing guide apply enhanced terms to ThaiESG units bought between 1 January 2024 and 31 December 2026: up to 30% of assessable income, capped at ฿300,000, and held for five years. ThaiESG is listed separately from the shared retirement-savings allowances; confirm your own remaining allowance before buying.

On 1 January 2027 the terms revert to ฿100,000 and an eight-year hold. There is 98 days left. This is not a market timing call — the deadline is written into a regulation.

SSF purchase eligibility ended after tax year 2024. That expiry does not say anything about the merits or holding requirements of units already owned.

A ThaiESG unit is still an investment fund with market, concentration and fee risk. Verify tax eligibility and compare the mandate, ongoing charge and drawdown risk before choosing a fund.

Evidence What produced this stance

The stance is a starting point produced by arithmetic, not by an opinion. Every reading behind it is printed below with its value and where the value came from; if you disagree with a reading, the stance it produced is worth disagreeing with too.

The Revenue Department's allowance guide limits qualifying SSF purchases to 1 January 2020 through 31 December 2024. Buying new SSF units in 2026 does not create that purchase allowance.

What would change this. Nothing in the markets changes this. It changes on 1 January 2027, or earlier if a new regulation is gazetted — which is the only thing worth watching.

The flip is named in advance on purpose. A stance that can only be explained after it changes is a story; a stance that names its own reversal beforehand can be held honestly, and can be checked later against what actually happened.

The score is the strength of the argument among the evidence that is currently available, from −100 to +100. It is not a forecast, a probability or an expected return. Anything between −30 and +30 is a genuine shrug and leaves the stance where it started.

Data coverage says only how many declared inputs exist today. It is not confidence, research strength or agreement among inputs. A reading that cannot be computed is shown as unavailable and counts for nothing — it is never quietly scored as neutral.

Exact score: Fixed structural rule; no market score and no ladder shift.

How Reaching this from Thailand

The routes are the ways this is actually reachable from Thailand. They are not equivalent. The same fund bought through a Thai broker and through an offshore account attracts different tax, different limits and, in one case, a US estate tax exposure that has nothing to do with the fund itself.

Thai fund (tax wrapper) A Thai mutual fund bought for the tax deduction

RMF and ThaiESG funds reduce this year's income tax in exchange for a holding period. The deduction is usually worth more than the fund's performance edge.

What to ask for What it is Ccy Ongoing charge Why this one
ThaiESG Thailand ESG Fund
A Thai fund that cuts this year's income tax bill by up to ฿300,000 of deduction in exchange for holding five years.
 THB — Use only a qualifying registered fund after verifying eligibility. Compare mandate, ongoing charge and risk; the tax label does not make funds equivalent.

Last year of ThaiESG's enhanced deduction

Closes 2026-12-31

Ministerial Regulation No. 395 and the Revenue Department's filing guide apply the enhanced terms to units purchased between 1 January 2024 and 31 December 2026: up to 30% of assessable income capped at ฿300,000 and held five years. From 1 January 2027 through 31 December 2032 the cap is ฿100,000 and the hold is eight years. The cash value depends on the taxpayer's actual assessable income, marginal rates, other allowances and compliance; the fund itself still has Thai-market risk. SSF purchases qualified only through tax year 2024.

Eligible taxpayers can claim up to 30% of assessable income, capped at ฿300,000, for qualifying ThaiESG units bought by 31 December 2026 and held five years. From 2027 the cap is ฿100,000 and the hold is eight years.

Friction What this costs regardless

The frictions are the parts that cost money or attention regardless of whether the argument is right: tax, transfer limits, deadlines, structure. For most people most of the time they matter more than the market reading does.

ThaiESG's enhanced terms end 31 December 2026

deadline
฿300,000 of deduction on a five-year hold, separate from the retirement cap — and from 2027 it drops to ฿100,000 on an eight-year hold.

Ministerial Regulation No. 395, published in the Royal Gazette on 3 December 2024, applies enhanced terms to ThaiESG units purchased between 1 January 2024 and 31 December 2026: a deduction of up to 30% of assessable income capped at ฿300,000, a five-year holding period, and — the part that matters most — a ceiling entirely separate from the ฿500,000 retirement ceiling that RMF and provident fund contributions share. From 1 January 2027 the terms revert to ฿100,000 and eight years. This is the single most concretely dated item in the whole file: the enhanced version of this deduction has a fixed expiry and no announced successor.

SSF is over — do not buy it for the deduction

deadline
The Super Savings Fund deduction expired after tax year 2024. Several official pages still describe it as available; they are stale.

The SSF regime ran for tax years 2563 to 2567 — 2020 to 2024 — and 2567 was the last deductible year. This was confirmed negatively from the Revenue Department's own personal income tax filing instructions for tax year 2568, which no longer carry the deduction. Both rd.go.th/557.html and the SEC's own insight-fund site still list SSF as live; both are wrong for 2026. Units already held continue to run their ten-year holding period from each individual purchase date, so legacy holdings are not affected — only new purchases, which now buy no deduction at all.

RMF locks money until 55

deadline
Deducts up to 30% of income, capped at ฿500,000 combined with all your other retirement schemes — but you cannot touch it before age 55.

A Retirement Mutual Fund deducts up to 30% of assessable income, subject to a ฿500,000 ceiling shared with provident fund, GPF, national savings fund and pension life insurance contributions together. The conditions are a holding period of at least five years from first purchase AND age 55 or over at redemption, with purchases made annually allowing at most one consecutive skipped year. The old minimum of 3% of income or ฿5,000 has been abolished. Note that rd.go.th/60059.html still shows a 15% figure and references LTF; that page was last updated in 2021 and is stale.
