The short version
Thailand's Revenue Department has issued Royal Decree No. 803 (B.E. 2569 / 2026) on deductible expenses against assessable income — a tax measure aimed at supporting creators of artistic work. Two things matter for creative freelancers.
- Income under Section 40(6) in the liberal-profession category of fine arts (ประณีตศิลปกรรม) now gets a 60% lump-sum expense deduction, up from 30%. This is permanent, applies to all types of artists, and is effective from tax year 2568 (2025) onward.
- Buyers of paintings or sculptures from qualifying Thai artists get an exemption for the actual amount paid, capped at THB 100,000 per tax year, for purchases made from the Cabinet resolution date through 31 December 2026. Ordinary partnerships and non-juristic bodies of persons are excluded.
The first is a permanent structural change. The second is a deadline-driven opportunity that expires at year end. Both change how you should be labelling income and writing documents — not just what you type into a form next March.
What 30% to 60% is actually worth
Say you earn THB 800,000 from fine-art work this year and claim only the standard personal allowance of THB 60,000.
Old rate, 30% lump sum
- Deduction of 240,000 leaves assessable income of 560,000
- Less the 60,000 allowance leaves net income of 500,000
- Progressive tax due: THB 27,500
New rate, 60% lump sum
- Deduction of 480,000 leaves assessable income of 320,000
- Less the 60,000 allowance leaves net income of 260,000
- Progressive tax due: THB 5,500
That is THB 22,000 of difference on 800,000 of revenue. The gap widens as income rises, because the income you remove always comes off the top brackets first. At revenue around a million and up, the annual saving moves into the tens of thousands immediately.
Which makes the real question not how much you save, but whether you qualify at all.
Fine arts is not a synonym for creative work
Section 40(6) is a closed list of liberal professions: healing arts, law, engineering, architecture, accounting, and fine arts. It is not a catch-all bucket for everyone who works independently.
Work typically treated as fine arts is work where high-level craft is the point and the piece itself is the product: painting, sculpture, printmaking, ceramics, handmade craft.
What most Thai freelancers actually sell usually falls elsewhere.
- Section 40(2) covers work performed to a client's instruction with essentially no cost base of your own — commissioned graphic design, copywriting, consulting. The lump-sum deduction is 50% but capped at THB 100,000, a ceiling you hit almost immediately.
- Section 40(8) covers contract work or a trade with genuine costs — a team, materials, equipment, subcontractors. Here you choose between actual expenses with receipts, or the statutory lump-sum rate for that class of business.
The dividing line is the nature of the work and how the money is made, not your job title. An artist selling their own paintings and a designer producing commercial artwork from a client brief may use overlapping skills, but the law sees two different income types.
If you do both — sell your own pieces and take commercial commissions — you have to split the totals. You cannot pool everything and apply whichever rate looks best to the whole pile.
Four things worth doing this month
1. Re-sort the year's income. Open every payment you've received and tag it: sale of your own work, or commercial commission. Doing this now takes an hour. Reconstructing it next March takes a weekend.
2. Make the paperwork say what you mean. The Revenue Department reads invoices and receipts, not intentions. If a payment is a sale of an artwork, name the piece, its dimensions and medium, and describe it as a sale — rather than writing a vague line item like design services fee.
3. Prepare documents for your buyers. The THB 100,000 buyer exemption only works with complete proof of purchase: both parties' names and tax IDs, the date, the amount, and a description of the work. For artists this is a genuine, non-pushy sales reason for Q4 — a hesitating collector now has a 31 December 2026 deadline.
4. If you already filed tax year 2568 at 30%. The measure applies from that year, so a qualifying artist who filed at the old rate can file an amended return and claim the difference. Refund claims for personal income tax are generally available within three years of the filing due date. Don't leave it on the table.
Caveats to track
- Read the full decree and any related director-general notifications on the Revenue Department's new-legislation page, especially on definitions and required evidence. If your work sits on the boundary, ask your local revenue office or your bookkeeper before filing rather than guessing.
- A lump-sum deduction frees you from keeping expense receipts, but not from proving your income is the type you claimed. The burden of proof moves from expenses to classification.
- Withholding tax rates are unchanged. Corporate payers still withhold 3% on 40(6) income; that money is credited or refunded when you file your annual return.
- The buyer measure has a hard stop at 31 December 2026. The 60% artist rate is permanent. Don't mix the two up.
Keeping it from becoming admin
The hard part of this measure isn't the arithmetic. It's knowing, all year long, which income bucket each payment belongs to. If your income lives across chat threads, bank transfer slips and three spreadsheets, year-end classification becomes a two-day job.
In MANA, quotations, invoices and receipts are issued in one place, tied to a client and a project, with withholding tax and VAT fields on the document itself. When everything sits in one list, answering how much you sold as artwork versus how much you billed as commissioned work takes minutes — which is exactly what Decree 803 just made valuable.
