🇯🇵 Tax Return / Income Tax Filing → Japanese

Treating a Tax Return / Income Tax Filing as ordinary prose is the single most common reason these files come back stamped "ไม่ผ่าน". The Thai original is, in effect, a controlled vocabulary disguised as a paragraph. Where the original ใบเสียภาษี (ภ.ง.ด.) reuses a registrar title in different tenses, the Japanese version must preserve the tense distinction — confusing "registered" with "is registering" changes the document's legal effect.

We translate ภ.ง.ด. 90/91 (personal) and ภ.ง.ด. 50 (corporate). Most embassies prefer the version with the Revenue Department's e-filing receipt page included.

Our Japanese desk maintains a glossary reconciled against:

• The Thai Ministry of Foreign Affairs Department of Consular Affairs
• The Japanese embassy in Bangkok
• Relevant universities, professional bodies, and court systems in Japanese-speaking jurisdictions

Translated to numbers, the rigour above means most Tax Return / Income Tax Filing packets we send into the Japanese chain return stamped on the first attempt, with rework restricted to a small tail of edge cases (mostly client-side document edits).

Plan to assemble a packet, not a single page — the Japanese side will usually expect the translated Tax Return / Income Tax Filing to arrive with several of the supporting items listed below.

• Visa financial proof — typically also needs your passport bio page and a recent photo.
• Mortgage application abroad — typically also needs your passport bio page and a recent photo.
• Sponsor income proof — typically also needs your passport bio page and a recent photo.

Chinese, Japanese and Korean offices read translated Thai documents against a fixed glossary of registry titles — "นายทะเบียน" must map onto the term their own internal forms use, not a literal dictionary translation.

For the Tax Return / Income Tax Filing specifically, our Japanese desk pays particular attention to:

• Dates & calendars. The Thai Buddhist year (พ.ศ.) must be converted to the Common Era; we provide both formats side-by-side.
• Official seals & stamps. Thai stamps and signatures are described in the target language so overseas officers can verify authenticity.
• Officer titles. Registrar, Chief District Officer and District Officer are kept distinct, mapped to whichever term the destination registry uses internally.
• Name transliteration. Japanese authorities check the translated name against your passport — any mismatch is grounds for rejection.
• Form codes. Original Thai reference numbers and registration codes are preserved verbatim.

Our standard pipeline runs through eight gates; each one is logged in a case file you can audit later:

1. Document intake. Send us a high-resolution PDF/photo of the original Tax Return / Income Tax Filing. We verify it is a current Amphur or court-issued copy.
2. Translation into Japanese. Performed by our credentialed translator recognised by the Japanese embassy in Bangkok. Names, dates and registration numbers are cross-checked against your passport.
3. Delivery. Pickup at our office, courier in Bangkok, EMS across Thailand, or DHL Express to 200+ countries.
4. Japanese embassy attestation. We submit to the destination embassy in Bangkok and collect the legalised document.
5. Notary Public (if required). One of our six in-house Notarial Services Attorneys notarises the translation, which most embassies require.
6. Company certification. We affix our official translator seal and a signed declaration accepted by Thai MFA.
7. Second-eye QA. A senior reviewer cross-checks every page against the source and flags any name/date inconsistency before the seal is applied.
8. Thai MFA legalisation. Our courier files at the Department of Consular Affairs (Chaeng Watthana) the next working day. Standard return: 3–5 working days.

For budgeting, the 3-page Tax Return / Income Tax Filing on the Japanese pipeline carries the line items below; the case manager confirms the exact total before any gate is touched:

• Translation: ฿800 – ฿3,840 (includes company seal & certifying statement, MFA-accepted).
• Notary Public (Notarial Services Attorney): ฿1,500 – ฿4,000 per document if required by the destination.
• Thai MFA legalisation: ฿800 – ฿1,500 per document.
• Japanese embassy attestation: ฿2,500 – ฿12,000 per document depending on embassy.

Final fees vary with page count, urgency (a 4-hour rush carries a 50–100% premium), and whether the embassy requires an extra sworn affidavit. Send a scan via LINE @NYCLI or email nyclegal@ilc.ltd for a fixed quote inside 15 minutes during business hours.

Almost every rejection of a Tax Return / Income Tax Filing we are asked to fix afterwards comes back to one of these five patterns:

• Missing MFA or embassy gate — most Japanese authorities require both, not just one.
• Out-of-date copies — embassies usually want a Tax Return / Income Tax Filing issued within the last 3–6 months.
• Photocopies submitted instead of originals with attached translation.
• Names spelled differently across passport, Tax Return / Income Tax Filing and supporting documents — Japanese authorities require an exact match.
• Translations done by uncertified translators that lack the MFA-accepted seal.

Budget two working days for the translation itself; the legalisation chain adds the days after that. Adding MFA legalisation extends the total to 4–7 working days. Embassy attestation adds another 3–10 working days depending on the destination.

For urgent cases we offer:

• 4-hour rush translation — surcharge of 50–100%.
• 1-day express MFA — additional government fee, file before the 09:30 cut-off.
• Embassy priority queues — available with most embassies in Bangkok at a small handling fee.

The vocabulary table below is the live reference our QA reviewers consult line-by-line; we publish it openly so the receiving Japanese counter can audit our terminology against their own:

• Certified translation / คำแปลรับรอง — translation accompanied by a signed declaration of accuracy; required by MFA.
• Transliteration — converting Thai script names into Japanese characters; must match the spelling in your passport.
• Apostille — single-step alternative to MFA+embassy for Hague Convention members (Thailand: not a signatory yet → MFA route applies).
• Notarisation / รับรองโนตารี — a Notarial Services Attorney certifies the translator's signature or the copy; required by some Japanese authorities.
• Embassy attestation / รับรองสถานทูต — the Japanese embassy in Bangkok validates the Thai MFA stamp.
• Sworn translator / ผู้แปลสาบาน — translator officially registered with a foreign court or ministry; relevant for Japanese in some EU jurisdictions.
• MFA legalisation / รับรองกระทรวงการต่างประเทศ — the Department of Consular Affairs authenticates the translator's seal; mandatory for most overseas use.

NYC Legal & Notary is a Thai law firm registered with the Lawyers Council of Thailand. We operate six in-house Notarial Services Attorneys, a panel of more than 200 certified translators across 205 languages, and a dedicated MFA & embassy liaison team that visits the Department of Consular Affairs at Chaeng Watthana every working day.

For the Japanese pair your file is handled by translator recognised by the Japanese embassy in Bangkok who is screened on three criteria: native or near-native Japanese command, demonstrated court-grade legal-translation experience, and a clean track record with Thailand's MFA and the relevant embassy. Every translator signs an NDA covering attorney-client privilege.

Concrete reasons clients return

• Rejection insurance. If MFA or the Japanese embassy rejects our work due to a translation defect, we re-file at no charge and absorb the government re-filing fee.
• Confidentiality by default. Files are encrypted at rest, deleted from working storage 90 days after delivery, and never used as AI training data.
• Fixed-fee quotes within 15 minutes. No surprise charges after the work begins; the LINE quote is the invoice you receive on delivery.
• Bilingual case manager. One person handles your file end-to-end; ask questions in Thai, English or via your preferred language.
• Single-window service. Translation, Notary, MFA filing, embassy attestation and worldwide courier are booked once — you do not chase three vendors.
• EN, TH and Japanese support by phone, LINE, WhatsApp, WeChat, KakaoTalk, Telegram and email.

Because the pipeline ends at the same standard the destination authority opens their checklist against, the receiving officer's review is usually a verification rather than an evaluation. If the receiving office requests an additional step — for example a sworn translator's signature notarised in the destination country, or a translation re-done into a regional dialect — we provide a follow-up service from our partner network of overseas counsel.

• Affidavit of translation accuracy — a sworn statement signed before a Notary Public in the destination country; we prepare the bilingual template.
• Long-term archiving — your translated and legalised file is archived for 7 years; request a fresh certified copy at any time without re-paying for translation.
• Re-issuance — if the destination retains the original, we keep the certified scan on file and produce another legalised copy on 48-hour turnaround.
• Apostille substitution letter — for receiving authorities that mistakenly request an Apostille (Thailand is not yet a Hague signatory), we provide a notarised explanation letter accepted by most foreign registrars.
