Playbook: BOI Application

Short answer: what BOI Application actually involves

BOI Application is the process of document set and filing sequence for BOI. It requires 6 core documents, starting with a business plan and project description for the promotion application, and runs through 6 steps, from map the project to the activity category and the associated incentives to once promoted, implement the conditions and diarise reporting obligations. Roughly 2–6 months depending on the activity category. Certification is signed by a Notarial Services Attorney registered with the Lawyers Council of Thailand, and documents used abroad must be legalised in the order the receiving authority requires.

Key facts at a glance

All timeframes are approximations based on observed authority queues, not guarantees. Confirm with the receiving authority before booking travel or fixing a filing date.

Practical tips

• Have "a business plan and project description for the promotion application" ready first — it is the single most common cause of delay.
• Check that every document spells the name exactly as in the passport before submission.
• Confirm the accepted format with the receiving authority before "assemble corporate and technical documents for the application".
• Allow for roughly 2–6 months depending on the activity category plus public holidays in both countries.

Common pitfalls

• Submitting an old photocopy instead of "a business plan and project description for the promotion application" — many authorities reject it outright.
• Skipping "build the business plan and investment figures around the assessment criteria" and filing the next stage, which restarts the whole queue.
• Inconsistent spelling of proper nouns between documents in the same bundle.
• Counting the timeline from the day you send documents rather than the day the authority accepts a complete file.

How this differs from adjacent services

BOI Application needs 6 documents across 6 steps (Roughly 2–6 months depending on the activity category). The step that separates it from Corporate Documents and Special Business Licences and IP Registration is "Assemble corporate and technical documents for the application", where the other routes instead require Corporate Documents: Translate into English with company names and titles locked consistently · Special Business Licences: Prepare documents and bring the premises up to standard before inspection · IP Registration: Prepare the application and the power of attorney.

The table reflects each service's actual process; timeframes are approximate and depend on the authority's queue.

Realistic timeline, step by step

Working days for each link in the chain, separating the parts we run ourselves from the parts a government office controls. Plan backwards from your deadline using the upper figure, not the lower one.

Indicative total: 4–7 working days

Add a buffer of at least five working days before any flight, hearing or filing deadline. Documents that must travel abroad by courier need more.

Sending BOI Application abroad: which certification route each destination accepts

This table shows the route a Thai-issued BOI Application document must follow to be accepted in each destination today, and how that changes once the Apostille Convention enters into force for Thailand on 28 February 2027.

Party status follows the HCCH status table; Thailand's entry into force is 28 February 2027. Embassy fees and queues vary, so confirm with the receiving authority before filing. If you would rather not run this yourself, we review the documents, prepare the translation and file with every authority end to end.

Who BOI Application suits, and when to bring in an adviser

This matter starts from 6 source documents and runs through 6 stages, with an overall approximate window of Roughly 2–6 months depending on the activity category. If your paperwork is complete and you can file in person, doing it yourself is realistic. If any of the situations below apply, a pre-filing review materially reduces the chance of rejection.

Do it yourself or let our team handle it — BOI Application

Why files get rejected — BOI Application

The 5 most common reasons a BOI Application file is returned, each with a preventive action you can take before filing.

1. 1. Set assembled out of order at the "Assemble corporate and technical documents for the application" stage

   Order the bundle exactly as the destination specifies and attach a cover index so an officer can verify it quickly, which reduces returns.

2. 2. Name spelling does not match the passport

   Lock spelling to the passport page as the single standard across the whole set, and disclose former names with the change-of-name evidence.

3. 3. Certification format does not match what the destination requires

   Obtain a letter or email from the receiving authority stating the accepted format, and keep it as your reference at submission time.

4. 4. A trailing supporting document is missing, e.g. "Supporting documents specific to the activity category applied for"

   Keep a checklist and one full backup copy of the bundle so a correction round can be filed immediately without restarting.

5. 5. Incomplete scans, or stamped pages that are not legible

   Scan every page in colour, including blank and reverse sides carrying seals, then re-check against all 6 listed documents before sending.

If you would rather not risk a rejection or spend days at counters, our advisory team pre-checks the full bundle before submission. Reach us by phone, LINE or email.

Key terms to understand before starting BOI Application

These terms cause more rejected files in BOI Application than translation errors do. The definitions below reflect how Thai offices and receiving authorities actually apply them.

Sworn / accredited translator

A translator registered with a court, ministry or accreditation body (e.g. NAATI in Australia). Thailand has no European-style sworn-translator register, so certified translation plus legalisation is used instead.

Legalisation

The Department of Consular Affairs (MFA Thailand) certifies the signature and seal of the issuing officer, after which the destination embassy adds its own attestation. This is the standard route until Thailand's Apostille takes effect on 28 February 2027.

Power of Attorney (POA)

A document authorising another person to act within a stated scope. State the scope, validity period and reference numbers precisely — overly broad wording is a frequent rejection reason.

Receiving authority

The office that will actually use the document — a registrar, university, court or immigration bureau. Its written requirements, not the country's general practice, determine the format of the whole bundle.

Certified translation

A translation accompanied by a statement that it is complete and accurate, with the translator's name, signature, date and contact details. The exact wording accepted varies by receiving authority.

Name consistency

Every document must spell the name exactly as in the passport. If the name has changed, include the change-of-name evidence in the same bundle — otherwise the authority treats them as different people.

If you are unsure which case applies to you, send the document images and the name of the receiving authority. Our advisers, who have handled cross-border documents for over 15 years, will map the route that actually works for your file.

Pre-submission readiness checklist for BOI Application

Clear these seven checks before starting BOI Application and you remove almost every common cause of rejection. Each item states the reason so you can verify it yourself.

1. 1. Issue date still within the validity window the destination accepts (often 3 or 6 months)

   Why it matters: Status and company documents usually expire. If the certificate ages out while it is moving through multi-step legalisation, the whole chain must be redone.

2. 2. Signatory's authority matches the latest company affidavit and the registered signing format

   Why it matters: If the required combination of directors or the registered seal is missing, the document does not bind the company and fails at the very first certification layer.

3. 3. Name spelling identical across passport, ID/house registration, source document and translation

   Why it matters: A one-letter difference is enough for a receiving authority to treat you as a different person and reject the whole bundle. If the spellings genuinely differ, a same-person declaration must be prepared in advance.

4. 4. Decide the delivery method up front: in person, international courier, or filing by a representative

   Why it matters: Some authorities only accept envelopes sent directly by the issuer or by a law office. Knowing this early lets the bundle and the power of attorney be prepared in a single round.

5. 5. Translation covers every element: stamps, signatures, marginal notes and reverse-side text

   Why it matters: Reviewers compare page against page. An untranslated seal or back-page note makes the translation incomplete and blocks the next certification step.

6. 6. Keep a full copy set and digital scans of every certification layer before sending the originals abroad

   Why it matters: Originals are rarely returned. If the destination later asks for clarification, the retained certified copies answer it immediately instead of re-ordering the whole document.

7. 7. Colour scans at 300 dpi or better, full page edges visible, no shadows or cropped corners

   Why it matters: Many authorities reject tilted phone photos because seals cannot be verified. One clean re-scan is faster than waiting a week for a rejection notice.

If you would rather not run the checks yourself, send the document images and the name of the receiving authority. Our advisory team, with 15+ years on cross-border documents, reviews them before filing and then handles every certification layer through to the destination.

Service standards and advisory team for BOI Application

We do not simply "collect your papers and queue at a counter". Every BOI Application case starts by reading what the receiving authority actually accepts, then sequencing the certification chain correctly from the first document. Below are the standards we hold on every case, the people responsible, and the aftercare you get.

Service standards (SLA) we hold on every case

Six-layer quality check before delivery

Most BOI Application rejections are not about substance. They come from small details: a spelling that differs from the passport, a certification chain done out of order, or a document older than the destination accepts. So we re-check in layers:

1. 1) Source-document validity

   Confirm the copy is a type the destination accepts, freshly issued within the allowed window, with all seals and signatures present.

2. 2) Identity-data consistency

   Match names, dates of birth and document numbers against the passport and every other paper in the same bundle.

3. 3) Second-linguist translation review

   Translator and reviewer are never the same person; focus on legal terminology, authority names and transliteration of proper nouns.

4. 4) Certificate format check

   Certification wording, letterhead, binding and seal placement must match the format the receiving authority expects.

5. 5) Certification-order check

   Verify original → translation → certifying authority → embassy is correct before filing, so nothing has to restart.

6. 6) Delivery-set check

   Count the sets, verify high-resolution scans, and attach a note stating which authority each document is for.

The team on your case

A BOI Application case is never handled by one person alone — there is always a preparer and a reviewer. Our core team has worked on cross-border documentation for more than 15 years.

Aftercare

• We retain a digital copy of the bundle for the agreed period, so repeat sets can start immediately.
• We flag expiry dates on time-limited items such as police clearance certificates or company affidavits.
• Follow-up advice is included when the receiving authority asks for something extra — no need to open a new case.
• If a document is ever rejected, we take it back up at once with a written cause and the fastest available fix.

Information as of 2026 · These standards describe our own working practice. They are not a guarantee of any government or embassy decision. Timeframes are indicative and depend on official queues.

Handling this from outside Bangkok

BOI Application does not require you to travel to Bangkok for every step. Clients in these 10 provinces routinely run the whole file by courier with online status updates. Upcountry points are document hand-over points for our mobile team, not walk-in offices.

How the remote workflow runs

1. Send photos or scans first so we can confirm you are using the correct, still-valid version.
2. Ship the originals with tracking, together with a passport or ID copy.
3. We file with each authority in sequence and report progress at every stage.
4. Documents are returned to your address, or forwarded to the receiving party as agreed.

If your province is not listed, the service still works the same way, because the decisive filings happen with Bangkok authorities regardless. Our advisers, with more than 15 years of experience, pre-check the file before you ship it so no courier trip is wasted.
