Thai tax, accounting and double tax agreements — practical answers

First-party answers on the 180-day Thai tax residence test, foreign-sourced income remitted into Thailand, personal and corporate filings, statutory accounting under the Accounting Act B.E. 2543, and claiming double tax agreement relief — grounded in the Revenue Code and Revenue Department guidance. General information only, not a case-specific tax ruling. Our staff quote fees per matter by phone, LINE or email. (19+ search topics covered)

Do foreign employees file their own Thai tax return?

Yes. Even where the employer withholds tax, the income earner must still file PND.91 or PND.90 depending on income types, within the deadline announced by the Revenue Department for that tax year. Ask your employer for the withholding tax certificate (form 50 Tavi) as evidence. If you also remit foreign income into Thailand, treaty relief should be considered as part of the filing.

Is foreign income taxed in Thailand?

Section 41, paragraph 2 of the Revenue Code taxes a Thai tax resident on foreign-sourced income when that income is brought into Thailand. The Revenue Department issued Departmental Instructions Por. 161/2566 and Por. 162/2566 setting out how this is applied, covering assessable income arising from 1 January 2024 onwards. Outcomes vary with the year the income arose, the year of remittance and any treaty relief, so documents should be reviewed before filing.

How do I prove Thai tax residency for a double tax agreement claim?

The Revenue Department issues a Certificate of Residence (R.O.22) to a person who was present in Thailand for the periods set out in the Revenue Code and who files Thai returns. The application is supported by passport entry and exit records, tax filings and, where relevant, an employer letter. The foreign payer or tax authority normally also wants the certificate translated and legalised for use abroad, so plan the certification chain at the same time as the application rather than after it.

What is the Thai corporate income tax rate?

The standard rate is 20% of net taxable profit, with a half-year return (PND.51) and an annual return (PND.50). Reduced rates apply to qualifying small and medium enterprises under the royal decrees in force, and BOI-promoted activities may enjoy exemptions or reductions under their promotion certificate. Check the entity's specific status before computing.

Do foreign tax documents need certified translation for use in Thailand?

When submitted in support of a Thai filing or credit claim, foreign tax documents are generally accompanied by a certified Thai translation, and officers may ask for further evidence of authenticity. Taxpayer names, taxpayer identification numbers, tax years and currencies must be reproduced exactly; converting currency or restating a tax year inside a translation is treated as an error. If the destination is a foreign authority instead, check separately whether consular legalisation is required.

How are accounting and tax fees quoted?

Fees depend on document volume, monthly transaction count, VAT registration, industry and scope — monthly bookkeeping, year-end closing, filings, or advice on a single issue. We therefore quote per engagement. Send your company details and sample documents by phone, LINE or email and our staff will confirm scope and fees before any work begins.

Can I get a Thai certificate of residence for treaty purposes?

Yes, if you meet the Thai tax residence test and have filed Thai returns, you can apply to the Revenue Department for a certificate of residence (form R.O.22) to claim treaty benefits abroad. Supporting documents commonly include your passport with entry and exit stamps, evidence of your stay, and proof of Thai filings and tax paid.

Can a treaty claim be made after tax has already been withheld?

Refund or credit procedures exist in many treaties and in domestic law, but the deadline, the competent office and the evidence required are set by the country where the tax was withheld. Missing the statutory window generally ends the claim regardless of the merits, so confirm the limitation period before assembling documents, and keep the original withholding certificate rather than a copy.

Tax documents and Double Tax Agreement (DTA) claims

Claiming DTA relief usually requires a Certificate of Residence (R.O.22) from the Thai Revenue Department together with consistent income evidence, and the translation often has to be certified before use abroad.

Documents to prepare

  • • Certificate of Residence (R.O.22)
  • • Withholding tax certificate (R.O.21) where tax paid must be evidenced
  • • Filed returns: PND.90/91 for individuals or PND.50 for companies
  • • Passport / ID and evidence of days present in Thailand
  • • Contracts or documents showing the source of income

Step-by-step process

  1. 1. Confirm residence status — Verify that the day-count threshold is met for the tax year claimed.
  2. 2. Apply for R.O.22 — File the application with the Revenue Department together with income and filing evidence.
  3. 3. Align the supporting set — Figures in the returns, contracts and payment evidence must match.
  4. 4. Translate and certify — Where the destination requires another language, certify the translation at the Department of Consular Affairs.
  5. 5. Final legalization — Apostille or destination embassy, per the receiving tax authority's rules.

Pitfalls and rejection causes

  • • The tax year on the R.O.22 must match the year claimed, or the whole file is refused.
  • • Mismatches between filed figures and payment evidence trigger requests for more documents.
  • • Some countries require their own form signed by the Thai Revenue Department, not only the R.O.22.

Tips from our team

  • • Ask the receiving tax authority first whether it wants the R.O.22 or its own country form.
  • • Allow for Revenue Department processing queues, especially early in the tax year.
  • • Keep certified copies for the following year to avoid repeating the work.

Prefer not to handle the queues yourself, or worried about a rejection? Send us photos of your documents for a free pre-check. We handle the full chain — obtaining certified copies, translation, certification and submission — and keep you updated at each step. Reach us on LINE, phone or email during business hours.

Route Comparison

Comparing cross-border tax routes

Tax residence, treaty relief, and foreign tax credits are separate mechanisms; using the wrong one leads to double taxation.

RouteWhen to useCertifying authorityApprox. durationRejection risk
Certificate of tax residence (R.O.21 / R.O.22)You must prove Thai tax residence to a foreign tax authorityThe Revenue DepartmentVariable, depending on how complete your filed returns areMissing returns for the referenced year block issuance
Claim relief under a double tax agreementYou earn income from a country with a treaty with ThailandThe Revenue Department and the counterpart tax authorityVariable, per the mechanism that country appliesAssuming a treaty exempts all tax — most allocate taxing rights or grant a credit

Timelines above are practical estimates from live casework and can change with each authority's policy; confirm with the receiving authority before booking travel. If you would rather not test routes by trial and error, our advisers can assess which route fits your case.

Advisory Service

We do not just process documents — we advise you through the whole case

Our team has worked on cross-border documents, certified translation and government liaison since 2015. Most rejections we see are not caused by missing paperwork but by choosing the wrong route on day one, so we always start with a case assessment.

Route assessment

We look at your destination, purpose and deadline, then tell you which certification route applies — and which steps you can skip.

Pre-submission review

Name spelling, consistency across documents, document age and translation format are checked before anything reaches a counter.

Timeline planning

We sequence the steps around your appointment or travel date and flag bottlenecks in advance.

Rejection recovery

We read the refusal reasons, identify the underlying cause, and plan a resubmission that answers what the authority asked for.

Rather not learn by trial and error? Send your case details and document photos for a review — reach us on LINE, phone or email during business hours.

Practical Q&A

Practical questions · Near me / DIY / Required documents

Is there a service point near me?

Our only office is at Ladprao 95, Wang Thonglang, Bangkok. Clients elsewhere can send scans through LINE @nycvisa for an initial scope review, then agree how to provide originals if required. Contact us before visiting or sending documents.

Can I handle this myself?

Many steps can be done personally under the relevant authority's rules. What usually costs time is the wrong sequence, a translation format that does not match the requirement, or a source document version the recipient will not accept. Check the destination checklist before starting and ask us if anything is unclear.

Which documents should I prepare?

Generally the original document from the competent authority, the owner's ID or passport, a translation in the format the destination requires, and a power of attorney if someone acts for you. Details vary by service type — ask our team for a case-specific checklist.

What clients usually handle next

One document set often moves through several stages — translation, notarial certification, legalization and finally a visa filing. The links below follow that real sequence.

Choosing a document translation provider in Thailand

Pick a translation provider by the destination, not by turnaround alone. If the file goes to the Thai Department of Consular Affairs or an embassy, the translator must know the format that office accepts, not just the meaning. Verify three things: the certifier is named and identifiable, the destination accepts that certification format, and names, dates and document numbers match the passport character for character.

How to evaluate a provider

  • The certifier is named and identifiable — Consular offices and embassies check who certified the translation, not only the wording.
  • Knows the format the destination accepts — Each embassy differs: attached source copy, letterhead, or prior consular legalization.
  • Character-level verification — Mismatched name spelling and dates against the passport is the most common rejection cause.
  • Owns corrections after rejection — Submissions run on appointment dates; slow corrections cost the applicant the slot.
  • Documented custody of originals — Some civil registry documents are hard to reissue, so intake and return must be traceable.

Questions to ask before you commit

  1. If the receiving authority rejects or asks for changes, do you correct it, and under what terms?
  2. How can I track status, and who physically holds the original documents?
  3. Who will certify this translation, and will the certifier be named on the document?
  4. Does my destination require consular or embassy legalization afterwards?
  5. How many working days does it actually take, counted from a complete file?

FAQ on choosing a provider

Which translation service is recommended for embassy submissions?
Choose one that names the certifier on the translation, knows the exact format your embassy accepts, and verifies names and dates against the passport before certifying. Ask whether they also handle consular legalization so the file does not stall between two vendors.
Does a cheaper translation get rejected more often?
Rejection correlates with format and verification, not price. A translation is rejected when the certifier cannot be identified, the layout does not match the receiving office's requirement, or a name or date differs from the passport.
