How do I use the DTA to cut WHT?

Present the foreign Tax Residency Certificate + Thai CoR to the withholding agent before payment — they will apply the treaty rate instead of the domestic rate.

Dividend / Interest / Royalty / FTS rates?

Div 15% · Int 10% / 15% · Roy 15% · FTS 7.5% / 10% / 15%

What is the Service-PE threshold?

183 days within any 12-month period — beyond that, a PE arises and source-state tax applies.

Is the treaty MLI-covered?

Yes — Principal Purpose Test (PPT) applies. Arrangements with a principal tax-avoidance purpose lose treaty benefits.

Where are capital gains taxed?

Real-property + share-transfer gains in source state (Art. 13)

Can I claim a foreign tax credit?

Yes — Revenue Code §3 allows FTC up to the Thai tax otherwise due. Use Form CT-1.

How long for a Thai CoR?

RO.22 issued in 7–15 working days by the Revenue Department.

What does NYC Visa cover?

Cross-border tax mapping + CoR/TRC + DTA filing + MAP + BEPS substance + annual TP report

Why Choose NYC Visa & Translation

How to choose the right Thailand DTA · Vietnam provider in Thailand

Choosing the right Thailand DTA · Vietnam provider directly impacts the success and turnaround of your case. NYC Visa & Translation has worked with Revenue Department + GDT Vietnam since 2010, handling a broad real-world caseload across government documents, certified translations, and documents intended for use abroad. Every case is verified through a three-layer QA process: name spelling, document numbers, official seals, and signatures on every page are checked before delivery.

Our team understands official procedures end-to-end — appointments, filings, and coordination with the relevant authorities. You do not have to travel back and forth or risk rejection. Our Thailand DTA · Vietnam service supports Express handling that completes in half the standard turnaround.

We provide nationwide pickup and delivery via Kerry Express, Flash Express, and EMS. Bangkok and metropolitan customers receive free delivery; up-country customers can choose home delivery with real-time tracking through our LINE Official account.

Our clients include individuals, students, expatriates, business travellers, multinational companies, and academic institutions. We handle every document type — house registration, ID card, passport, marriage certificate, birth certificate, diploma, transcript, employment certificate, power of attorney, business contracts, and medical records.

Our Thailand DTA · Vietnam workflow runs in six clear stages: (1) receive originals and copies, (2) QA-audit the source for issues that would cause rejection, (3) translate through a native-speaker linguist, (4) certify with the authority required by the receiving country, (5) file and follow up at each government touchpoint, and (6) deliver plus retain a signed PDF you can re-download for five years. A single Case Officer owns your file end-to-end, eliminating hand-off errors that plague larger firms.

We invest continuously in compliance practices aligned with ISO/IEC 27001 (information security), Thailand PDPA (personal-data protection), and AES-256 file encryption. Every upload runs over TLS 1.3 only. Enterprise and law-firm clients can request an NDA before intake — our legal team signs same-day.

Beyond single-document work, we bundle end-to-end packages for clients preparing multiple certificates at once — e.g. a "moving abroad" bundle (house registration + birth + marriage + diploma + transcript with MFA + embassy) that reduces the number of trips and total lead time versus filing each item separately. Approval remains at the discretion of the receiving authority; contact our team for scope and fees.

What sets us apart is a 15-year direct working relationship with the destination authority — Revenue Department + GDT Vietnam — so we anticipate regulation changes, format tweaks, and queue timing before they hit your case, and brief you in advance. Approval outcomes always remain at the sole discretion of the authority; what we control is document completeness, formatting and lodgement timing.

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)

When is VAT registration required?

A business whose VATable turnover from goods or services exceeds THB 1.8 million per year must register for VAT with the Revenue Department within the prescribed period. The current rate is 7%, maintained by royal decrees renewed periodically. Registered operators must issue tax invoices, keep input and output VAT reports, and file monthly PP.30 returns.

What are a Thai company's annual accounting obligations?

The Accounting Act B.E. 2543 requires juristic persons to keep accounts, close financial statements for each accounting period and have them audited by a licensed auditor. The statements are then approved by shareholders and filed with the Department of Business Development, while the annual corporate income tax return PND.50 is filed with the Revenue Department within the statutory deadline.

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.

How is land and building tax assessed?

Under the Land and Building Tax Act B.E. 2562, the local administrative organisation where the property is located collects an annual tax based on use category: agricultural, residential, other use, or vacant land. The base is the official appraised value, while rates and reliefs are set by subordinate legislation that is revised from time to time, so confirm the notice in force for that year with the local authority.

What taxes arise when selling a Thai condominium?

At registration of transfer at the Land Office there is generally a transfer fee, withholding income tax computed under Revenue Code rules, and either specific business tax or stamp duty depending on holding period and the nature of the sale. Actual amounts depend on the appraised value, the sale price and the years held, so let our staff compute from the title deed or condominium ownership certificate before the transfer appointment.

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.

Do foreign tax documents need translation in Thailand?

Usually yes. Certificates of residence, foreign tax payment evidence and corporate documents used to claim relief normally need a certified Thai translation, and in many cases legalisation by the Department of Consular Affairs, Ministry of Foreign Affairs, before submission to a Thai authority. We review the document set and the order of certification before starting, to reduce rejections.

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.

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

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 for over 15 years. 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.

Practical Q&A

Practical questions · Near me / DIY / Required documents

Is there a service point near me?

Our main offices are Lat Phrao 95 (Bangkok), Khon Kaen and Udon Thani. We serve the whole country through scans and document courier, and can meet at city rail stations or malls. Ask our team by phone, LINE or email for the most convenient option.

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.
Practical advice & cautions

Accounting, tax and payroll: advice and cautions

Before you start
  • Seek advice before large cross-border transfers

    Cross-border transactions may trigger reporting duties. Prepare source-of-funds evidence before executing the transfer to avoid later queries.

  • Confirm personal tax residency before planning

    Thai tax residency depends on days present in the tax year under the Revenue Code. Establish status first, then consider foreign-sourced income questions.

  • Retain original records for the statutory period

    Tax invoices, receipts and accounting support must be kept for the period required by accounting law and the Revenue Code. Scans alone may not satisfy an audit.

  • Map statutory duties at the start of the year

    Financial statements to the DBD, tax filings to the Revenue Department and social security contributions are separate obligations with separate deadlines. Build one combined calendar.

Common reasons documents get rejected
  • Incomplete withholding tax certificates

    Missing withholding certificates prevent the payee from claiming credit and are a common dispute in retrospective reviews.

  • Filing on time but without supporting evidence

    Returns filed without verifiable documentation can lead to queries and later assessments.

  • Missing statutory filing deadlines

    Late financial statements carry penalties and can affect licence renewals or the next business visa application.

  • Assuming tax paid abroad removes the Thai filing duty

    Filing obligations and treaty relief are separate questions. Confirm residency status and the applicable treaty terms before concluding.

Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.

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 identifiableConsular offices and embassies check who certified the translation, not only the wording.
  • Knows the format the destination acceptsEach embassy differs: attached source copy, letterhead, or prior consular legalization.
  • Character-level verificationMismatched name spelling and dates against the passport is the most common rejection cause.
  • Owns corrections after rejectionSubmissions run on appointment dates; slow corrections cost the applicant the slot.
  • Documented custody of originalsSome civil registry documents are hard to reissue, so intake and return must be traceable.

Questions to ask before you commit

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

Your options, and who each suits

OptionBest forWhat to know
Freelance translatorInformal use where no authority certification is requiredMany embassies will not accept an uncertified translation.
Translation agency with certificationVisa, study and civil registry filingsConfirm the agency also handles the legalization step if the destination requires it.
End-to-end provider (translate + legalize)Files with a fixed appointment deadlineAsk which steps are in-house and which are subcontracted.

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.
