Why Rayong matters for Withholding Tax Filing
EEC + Map Ta Phut; petrochemicals and energy; the deepest mix of tax and land-use incentives in the country.
Operators in Rayong face area-specific filing windows, sub-district authorities and incentive overlays. We map your filing path to the correct กรมสรรพากร office in Rayong, not the Bangkok default.
Documents and prerequisites
Standard pack: company affidavit, shareholder register, board resolution, address proof in Rayong, and the specific schedules for Withholding Tax Filing.
For BOI/EEC overlays we additionally prepare zone proof, activity-code mapping and capex projections — the parts the revenue office expects to see signed by a registered professional.
Delivery model
Hybrid model: Bangkok subject-matter lead + regional liaison in Rayong. Filing is done locally; review and audit defence sit in Bangkok.
Clients receive a single point of contact and online status tracker — no need to call multiple offices.
Fees, timeline and incentives
Service fee from quoted on request. Government fees pass-through at cost. Lead time: ทุกวันที่ 7.
Where Rayong qualifies for BOI/EEC overlays, we model the incremental tax saving alongside the base filing so the value of the engagement is quantified up front.
