Full tax reporting application audit
A complete financial audit of the tax reporting applications prepared for a filing period — corporate income tax, VAT, and related schedules reviewed against source books.
Who this engagement is for
Finance managers and company directors who need an independent financial audit of the tax reporting applications their bookkeeper or outsourced accountant has drafted. Typical clients are Thai limited companies and foreign-owned entities with operations in Phuket, Bangkok, or multi-province trading.
Result you receive
A written audit memorandum covering each tax reporting application in scope: findings ranked by filing risk, recommended adjustments with journal references, and a short readiness statement for the period under review. You keep ownership of the filings; we do not file on your behalf unless separately retained.
Scope included
- Corporate income tax application pack (draft PND 50 / related schedules) for one accounting year
- VAT return applications for months or quarters agreed at kickoff
- Withholding tax schedules tied to the same period
- Tie-out of revenue, expense, and tax credit lines to the general ledger and bank summaries you provide
- Exit meeting (in person at our Phuket office or by video) to walk through material findings
Scope excluded
- Statutory financial-statement audit under the Accounting Professions Act
- Tax planning or restructuring advice
- Representation in Revenue Department disputes
- Reconstruction of missing source documents (we flag gaps; rebuilding books is a separate engagement)
How the work runs
- Scoping call — confirm entities, periods, and which tax reporting applications sit in the binder.
- Document intake — you share draft applications, trial balance, key ledgers, and prior-year assessments.
- Fieldwork — our reviewers test application lines against books and note exceptions.
- Draft memorandum — findings issued for your comments.
- Final report — signed PDF plus annotated schedule of open items.
Preparation
Have draft applications, chart of accounts, fixed-asset register, payroll summaries, and prior correspondence with the Revenue Department ready before kickoff. Incomplete binders lengthen the timeline; we will say so early.
Pricing basis
Engagements start at THB 85,000 for a single-entity annual CIT pack plus related VAT months. Multi-entity groups and messy ledgers are quoted after scoping. A 40% retainer confirms the slot; the balance is due on delivery of the final memorandum.
