- Monitor the 1.8M THB VAT ThresholdWe alert you before you hit the limit, helping you prepare for VAT registration or legally plan separate tax entities.
- Manage 40(8) Taxes (Standard vs. Actual)We analyze your costs to determine whether you should use the 60% standard deduction or keep actual receipts to minimize your tax burden.
For Freelancers & Contractors
- Categorize Income Types (40(2) to 40(8))General freelance work, professional services, or contracting have different deduction rates. We categorize them correctly.
- Claim Withholding Tax Refunds (3%)We compile the 50 Tawi certificates your clients deducted to claim refunds from the Revenue Department (if applicable).
