Most Thai freelancers meet income tax first and VAT much later — usually the moment a corporate client replies with one short line: “Can you issue a tax invoice?” It sounds like a paperwork question. It is actually a question about whether you are inside the VAT system, and the answer reshapes your pricing, your documents, and your monthly calendar for years.
฿1.8 million is not a tax bracket. It is a switch that changes your job
Personal income tax is charged on profit after expenses and allowances, and the rate climbs in steps. VAT does not work that way at all. VAT is not a tax you pay — it is a tax you collect from your client on behalf of the state and hand to the Revenue Department. That money passes through your bank account without ever being your income.
So registering for VAT does not directly make you “pay more tax.” It hands you a new set of duties: issue tax invoices, keep sales and purchase reports, and file every single month. Those duties do not pause in a month when no work comes in.
The law says that anyone regularly selling goods or providing services with gross receipts before expenses exceeding ฿1.8 million per year must apply for VAT registration (form PP.01) within 30 days of the day receipts crossed the threshold. Not at year end. Not when you file your annual return. The word receipts matters enormously: it is the full amount clients pay you, not what is left after costs. A freelancer who takes on production work and subcontracts half of it may keep well under half as profit — but the VAT threshold counts the whole figure.
How to count it without getting caught out
- Count only receipts from goods or services that are subject to VAT. Salary from an employed job does not go into the tally.
- Count cumulatively through the tax year, and watch it as you go — not in a panicked review each December.
- Some services are VAT-exempt (medical care, formal education). But design, web development, marketing, content, photography, editing and translation work all fall squarely inside the VAT net.
- If you are confident you will cross this year, you may register voluntarily in advance rather than waiting for the line.
What actually changes the day you register
Once the Revenue Department approves you, five things become routine work.
- Add 7% VAT on top of the service value on every invoice you raise.
- Issue a full-form tax invoice, which must carry the words ใบกำกับภาษี, the name, address and tax ID of both you and the buyer, a number and date, the service description, the value, and the tax amount shown separately. An ordinary receipt does not substitute.
- Maintain sales and purchase tax reports that can withstand inspection.
- File PP.30 every month, by the 15th of the following month — including a nil return in months with no income.
- Claim input VAT. Equipment, software, office rent and advertising with proper tax invoices become real credits against the VAT you collected.
The timing rule that protects your cash flow
For services, the VAT liability generally arises when payment is received, not on the date you send the invoice — unless you have already issued the tax invoice or the service has already been used. For freelancers on 45- or 60-day client payment cycles this is critical. Issue the tax invoice the moment you send the bill, and you may end up remitting VAT to the Revenue Department out of your own pocket before the client has paid you anything.
The safer habit: send an invoice to request payment, then issue the tax invoice / receipt on the day the money actually lands. If a corporate client needs the tax invoice earlier for their internal approval process, discuss openly how that shifts your remittance timing.
What the numbers look like on the bank slip
Say your fee is ฿100,000.
- VAT at 7% = ฿7,000, so the invoice total is ฿107,000.
- A corporate client withholds 3% tax on the service value (not on the VAT-inclusive total) = ฿3,000.
- Cash landing in your account: ฿104,000, plus a withholding tax certificate (50 Tavi) for ฿3,000.
- Of that, ฿7,000 is not yours. It goes to the Revenue Department by the 15th of next month, less any input VAT you can offset.
Most freelancers who get burned by VAT are not burned by the law. They are burned because that ฿7,000 quietly funded a slow month.
Does VAT make you more expensive? It depends entirely on who your clients are
This is the heart of the decision, and the honest answer differs person to person.
- VAT-registered company clients. Their real cost does not change, because they reclaim the ฿7,000 as input tax. Many actively prefer suppliers who can issue tax invoices, because it makes their own books clean. For this group, VAT is barely a pricing issue at all.
- Individuals, small shops, and non-registered businesses. To them your price just rose 7%, because they cannot claim it back. If this is most of your client base, voluntary registration before you must is usually a bad trade.
- Overseas clients. Exported services used abroad may qualify for the 0% rate, which is meaningfully different from exempt — you still recover input VAT. But it requires documentation that meets Revenue Department conditions, so get advice before you promise anything in a contract.
The one contract line that prevents an argument
The classic dispute: you agree ฿100,000, then the invoice arrives at ฿107,000 and the client feels something was added behind their back. State it in the quotation from day one — “price excludes 7% VAT” or “price includes VAT” — and note whether 3% withholding tax applies. Two lines remove the single most tedious conversation in freelance life.
Four questions before you register voluntarily
- What share of revenue comes from corporates? If VAT-registered companies are more than half your income, joining the system barely dents your competitiveness.
- How much input VAT do you genuinely have? If you buy gear, hire subcontractors and pay for software with proper tax invoices every month, input credits are real money back. If your main cost is your own hours, there is almost nothing to offset.
- Can you hold a monthly rhythm? PP.30 waits for no one. Answer honestly whether you will file on time every month, or whether you should hire a bookkeeper from month one.
- Leaving is harder than joining. Deregistration requires an application (PP.08), and the Revenue Department will generally want to see receipts genuinely below the threshold over a sustained period — while you keep filing monthly throughout. Confirm the current conditions before you decide.
A 90-day plan before you reach the line
The worst version of this story is realising you crossed three months ago. Four moves stop that.
Month 1 — make the running total visible. Keep a live “receipts year to date” number in front of you, and set your alarm at ฿1.5 million rather than ฿1.8 million so you have room to breathe.
Month 2 — talk pricing with your main clients. Tell them 7% VAT will appear on invoices from next quarter. Corporate clients understand VAT perfectly well; what they dislike is a new number arriving unannounced.
Month 3 — prepare documents and tooling. Gather your ID copy, house registration, proof of business premises, a location map, and evidence of receipts. Then decide what will issue your tax invoices and who will file PP.30.
After registration — lock the calendar. The 15th is the deadline every month, and the 7% should leave your spending money the instant it arrives. The simplest discipline in the world: sweep the VAT portion into a second account on every payment received.
If you only just realised you crossed the line
Do not wait to be contacted. Late registration and back-dated remittance carry surcharges and penalties, but voluntarily correcting your position before an audit always leaves you in a better place than being assessed after one. Reconstruct your monthly receipts, then work with a bookkeeper on the order of filings.
Choosing tools by asking who presses “file”
Thailand has genuinely good options here, and they are good at different things.
FlowAccount and PEAK are strong full accounting platforms — input/output VAT reports, financial statements, and smooth collaboration with accounting firms. If you already have a bookkeeper, or you are heading toward incorporating, that is the most direct fit. Leceipt specialises in signing and submitting e-tax invoices. Express remains the desktop standard many Thai accounting offices have run for decades.
MANA is not trying to be a company's general ledger. It is a workspace for one freelancer, where the work, the paperwork and the money sit together. You quote with VAT stated explicitly, convert to an invoice, issue the tax invoice when payment lands, file the 50 Tavi certificate against the project, and watch your year-to-date receipts so you know exactly how far you are from ฿1.8 million. The PP.30 filing itself still goes through the Revenue Department's e-Filing system or your bookkeeper — what MANA removes is the scramble to assemble correct numbers and documents at the deadline.
If you are far from the threshold and have no bookkeeper, paying for full accounting software today is probably premature. If you can see this year going over, start the bookkeeper conversation before you cross.
The numbers as they stand in 2026
The statutory VAT rate in the Revenue Code is 10%. The government has held it at 7% (6.3% plus local tax) for decades through royal decrees renewed in cycles. Most recently, on 27 July 2026 the cabinet approved extending the 7% rate for another year, covering 1 October 2026 to 30 September 2027, pending publication of the decree in the Royal Gazette.
For freelancers the real lesson is not when 7% expires — it is that this rate is always on a renewal cycle. Quote VAT-exclusive prices as standard, and a future rate change becomes an arithmetic update rather than a renegotiation of your entire client list.
A short checklist before you close this page
- Do you know your year-to-date receipts, and how far they are from ฿1.8 million?
- Have you set an alert at ฿1.5 million?
- Do your quotations state clearly whether the price includes VAT?
- If registered, does the VAT portion leave your spending balance the day money arrives?
- Who files PP.30 on the 15th of every month?
This is general guidance. Complicated cases — exported services, mixed income types, exempt activities — deserve a check with the Revenue Department or a qualified accountant before you act.
If you want to start with the first item, MANA shows your year-to-date receipts and carries a job from quotation to invoice to tax invoice in one place, so you see the ฿1.8 million line coming well before it arrives.
