Monthly Tax Filing
- 1. Value Added Tax (VAT) – Form P.P.30
VAT-registered businesses must calculate the difference between Input VAT (paid on purchases) and Output VAT (collected from sales). We manage the full process of preparing and filing the monthly P.P.30 return, ensuring the correct remittance of the net VAT liability to the Revenue Department.
- 2. Withholding Tax (WHT) – Forms P.N.D. 1, 3, 53
When making specific payments, such as salaries (P.N.D. 1), services, or rent (P.N.D. 3 or 53), a company is legally required to withhold a percentage of the payment. We handle the timely calculation, deduction, and remittance of these taxes to the Revenue Department monthly on behalf of the recipients.

- For Personal Income Tax: The tax year is the standard calendar year (January 1st to December 31st).Â
