Thailand Stamp Duty — 8-Instrument Comparison 2026 (Lease 0.1% · Loan Cap 10k · POA 30 THB · Share 0.1% · Guarantee Cap 10 THB · Non-Life Ins 0.4%)

quoted on request (ordinary cheque) / quoted on request per 2,000 = 0.15% (Bill of Exchange) / quoted on request per 2,000 = 0.25% (Promissory Note)

Cheque: flat 3 THB per instrument · B/E and P/N have no cap

Cheque: flat rate · B/E and P/N: face value

Drawer — banks typically impress stamps on chequebooks at issuance

Impressed stamp on standard bank chequebooks — no extra stamp by users · non-bank B/E and P/N require e-Stamp

Stamp on or before issuance · post-dated cheques use the date on the face

🎯 Prefer bank cheques over P/Ns for cash-like transactions — 3 THB per cheque vs 0.25% of face value · corporate P/Ns have no duty cap, dangerous at large amounts · e-cheques / e-B/Es issued via NDID/ITMX are pre-stamped

🚨 Inter-company P/Ns used in lieu of loans cost 0.25% with no cap — far pricier than a Loan Agreement (10k cap) at large amounts · RD scrutinises post-dated cheques and can reclass them as loans · cross-border B/Es drawn in Thailand incur Thai stamp

Corporate trade finance · quoted on request P/N incurs 0.25% = 30,000 THB (no cap) · switching to a Loan Agreement caps duty at 10,000 THB (saves 20,000) · NYC Legal advisory 8,500 THB

quoted on request (for amounts ≤ 1,000) · quoted on request per 1,000 (0.5%) for 1,000-10,000 · quoted on request (cap) for amounts > 10,000

🔺 Cap: quoted on request per contract (once amount > 10,000) — a THB 100M guarantee costs just 10 THB

Guaranteed amount — covers Bank Guarantees, Personal Guarantees, Corporate Guarantees

Guarantor / Surety pays the stamp duty

Adhesive stamp (personal guarantees) or e-Stamp · Bank Guarantees (LG) typically use impressed stamps on the bank's standard form

Within 15 days of signing · amendments (increased limits) require additional stamping (still within the 10 THB cap)

🎯 The 10 THB cap makes large guarantees very cheap — a THB 500M corporate guarantee costs just 10 THB · prefer over Collateral Pledge (higher duty + fees) when possible · shareholder personal guarantees replace corporate guarantees for SME loans · cross-border guarantees issued abroad get stamped when used in TH

🚨 Unstamped guarantees inadmissible in court (Sec.118) — creditors bear heavy loss · continuing guarantees without a limit may be treated as indeterminate → stamped on best-estimate basis · intercompany guarantees need arm's-length Guarantee Fees under Transfer Pricing rules

Group guarantee · Thai parent guarantees USD 8M for a Singapore subsidiary · Thai duty 10 THB but requires 0.5-1.5%/yr arm's-length Guarantee Fee · NYC Legal structuring + TP memo 45,000 THB

0.1% of the contract sum

No cap · additional stamp duty due on any contract-sum increase

Full contract price / consideration (before WHT) · includes reimbursable expenses spelled out in the contract

Contractor pays the stamp duty (Sec.103 + Schedule)

🔒 e-Stamp mandatory (Notification 58/2022) if executed in Thailand · foreign contracts signed in TH or with effect in TH are stamped in Thailand

Within 15 days of signing · amendments / variation orders stamped within 15 days of signing

🎯 (1) Split 'Materials Sale' (VAT 7% · no stamp) from 'Labor' (0.1% stamp + 3% WHT) — cleaner + lower WHT · (2) list reimbursables in a separate Annex outside the Contract Sum · (3) multi-year MSA with a single total price cuts paperwork · (4) cross-border services without effect in TH = no Thai stamp

🚨 Foreign consulting contracts with effect in TH = Thai stamp + 15% WHT (non-treaty) · unstamped change orders inadmissible · 'Fixed Price Turnkey' often reclassed by RD into Sale + Hire — split the base · employment contracts are NOT hire-of-work and owe no stamp duty

Bangkok office interior fit-out · contract sum quoted on request.8M (design + fabrication + install) split into (a) design 800k → duty 800 (b) materials 3,000k → duty 0 (c) labor 1,000k → duty 1,000 · total duty 1,800 · NYC Legal structuring fee 15,000 THB

quoted on request per quoted on request of premium = 0.4% of premium

No cap · Life Insurance falls outside Stamp Duty (subject to 2.75% SBT instead)

Gross premium (after discount) · excludes VAT · excludes reinsurance premiums

Insurer stamps the original policy · renewals stamped fresh each time

🔒 e-Stamp mandatory (Notification 58/2022) · filed with monthly OIC data · e-Policies issued via the Insurance Bureau are stamped automatically

Within 15 days of policy issuance · renewals stamped fresh each time · premium-increasing endorsements require additional stamping

🎯 (1) Splitting Fire + Motor + Health into separate policies vs a package may unlock group discounts that shrink the base · (2) ceded reinsurance is not re-stamped (only the ceding insurer stamps) · (3) cross-border marine insurance with Thai insured requires Thai stamp · (4) e-Policies via the Insurance Bureau cut admin cost

🚨 Direct foreign insurance without an OIC licence breaches the Non-Life Insurance Act 1992 — the buyer bears liability · un-restamped renewals are inadmissible when a claim arises · endorsements adding coverage without extra stamping are void

Corporate fire policy · BOI-approved Navanakorn factory · Sum insured 480M, premium 1.2M/year · duty 0.4% = 4,800 THB · NYC Legal compliance package (Master + Sub-Policies for 12 sites) 65,000 THB/year

0.1% of total rent over the lease term

No cap · unspecified term deemed 3 years · leases > 3 years must be registered at the Land Department

Total rent over the term + Key Money + any other consideration

Landlord is the payer · Tenant cancels the stamp (Sec.107)

🔒 e-Stamp mandatory (Director-General Notification 58/2022) · file Form AS.4 via RD e-Filing · pay by QR/ATM/credit card

Within 15 days of signing · leases > 3 years must be registered at the Land Department within 15 days (extra 1% registration fee)

🎯 (1) Report full rent + Key Money in the base — hiding it triggers 6× surcharge on reclass · (2) leases < 3 years skip Land Department registration, saving the 1% fee · (3) 3+3+3 renewal chains rejected by Supreme Court 6763/2560 — use original lease + fresh lease after expiry · (4) BOI/EEC-approved leases still owe stamp duty

🚨 Missing the 15-day window = 6× surcharge (5× penalty + base) · under-stamped instrument inadmissible as court evidence (Sec.118) · undisclosed Key Money = RD reassessment + penalty · subleases require fresh stamping · corporate lease > 3 years not registered = rights cannot be assigned

Sukhumvit long-stay condo lease · quoted on request/month × 12 = 720,000 + Key Money 100,000 · base 820,000 · duty 820 THB · NYC Legal draft + e-Stamp fee 4,500 THB

0.05% of loan principal (quoted on request per quoted on request)

🔺 Cap: quoted on request per contract — loans > THB 20M pay a flat 10,000 THB

Contractual loan principal only (no interest) · revolving OD uses the maximum facility limit

Lender pays the stamp duty · applies to individuals and companies alike (Sec.108)

e-Stamp (recommended) or adhesive stamp · banks / financial institutions use impressed stamps on standard forms

Within 15 days of signing · revolving OD stamped once when the facility is opened (no re-stamp on redraws within the limit)

🎯 The 10k cap keeps big deals cheap — a THB 500M corporate loan pays just 10,000 THB (0.002%) · intercompany loans still need stamping · cross-border loans signed in TH need Thai stamp · Master Loan Agreement + drawdown notices → stamp only the master (10k cap)

🚨 Oral loans are hard to enforce and can be reclassed as income by RD · late stamp = 6× surcharge (capped 100,000 THB per case) · director-company IOUs closely scrutinized — must bear market-rate interest · deeds of amendment raising the facility need extra stamp on the increment

Shareholder loan · LLC + director, THB 45M at MLR-1% · nominal duty 22,500 but capped at 10,000 THB · NYC Legal draft + TP memo 25,000 THB · shields against deemed-dividend reclass (10% WHT)

quoted on request (single-person single-act) / quoted on request (general or multi-matter) / quoted on request per person (multi-attorney acting separately)

No cap · corporate POA covering multiple matters = 30 THB per document

Fixed by POA type · no percentage of value · consular POAs signed abroad are stamped when used in Thailand

Principal / Grantor — stamped on the original given to the attorney

Adhesive stamp (cancelled) or e-Stamp via RD · foreign POAs require Notary + Apostille (from 28 Feb 2027) + Thai stamp when used

Stamp on or before the date of use · Apostilled foreign POAs stamped when brought into Thailand for use

🎯 (1) One general POA (30 THB) beats many single-act POAs (10 × N) once N > 3 · (2) Consular POA + Apostille (from 28 Feb 2027) trims the chain from 3 steps to 2, saving 3-4 weeks · (3) Board Resolution + Corporate POA replaces multiple individual signatures · (4) Notarized POA pairs well with fintech e-KYC

🚨 Uncancelled stamp = treated as unstamped · foreign POA without Notary + Apostille (after 28 Feb 2027) rejected in Thailand · overly broad general POAs refused by Thai agencies — list specific acts · POAs void automatically if attorney dies / entity dissolves

US investor · single general POA authorising a Thai attorney to manage share registers for 8 companies · duty 30 THB · US Notary + Apostille (from Feb 2026) takes 5 days vs 21 days for MFA + embassy · NYC Legal draft + Apostille + Thai registration 18,500 THB

0.1% of paid-up value or transaction price (whichever is higher)

No cap · SET/MAI-listed shares are exempt (Royal Decree 10/1957) · private-company shares are stampable

Paid-up value or transaction price (higher) · abnormally low prices are substituted with Fair Market Value by RD

Transferor — seller or donor of the shares

🔒 e-Stamp mandatory (Notification 58/2022) · file with Form AS.4 · attach share certificate + transfer deed + Board Resolution

Within 15 days of transfer (before recording in the shareholder register) · late filing incurs 6× surcharge

🎯 (1) SET/MAI trades are exempt (RD 10/1957) · (2) Private transfers below Book Value are reset to Fair Value by RD Ruling 0702/9420 · (3) share swaps / M&A exchanges still owe stamp on value · (4) nominee transfers without consideration still owe stamp on FV · (5) BOI/EEC company share transfers get no exemption

🚨 A quoted on request sale is reset to FMV + 5% gift tax if annual gifts > 20M · foreign buyers holding > 49% of a Thai company violate the Foreign Business Act 1999 · unstamped transfers are incomplete — the share register cannot be updated · nominee trust deeds risk prosecution under the 2022 Anti-Nominee amendments

Founder exit · 30% startup stake (book value 45M, sale price 180M) · duty 0.1% × 180M = 180,000 THB · NYC Legal M&A package (SPA + DD + filing + tax structure) 285,000 THB
