How the numbers work
Under the EOPT Act (RA 11976), the Invoice is now the single principal document for both goods and services — so for services you issue a Service Invoice. What appears on it depends on your BIR registration:
| Your status | On the invoice | Your own tax |
|---|---|---|
| VAT-registered | Add 12% VAT on your sales (VATable, or shown as VAT-exempt / zero-rated) | Remit output VAT, net of input VAT |
| Non-VAT | No VAT added — the amount is the sale | 3% percentage tax on gross sales (Sec. 116) |
When your client is a withholding agent, they deduct a creditable expanded withholding tax (EWT) — typically 2% on services or 5%–10% on professional fees — computed on your income net of VAT. It lowers the cash you collect today but is creditable against your income tax (via the BIR Form 2307 your client issues), so it isn't an added cost. The generator shows both the total billed and the net you actually collect.
Version 1.0 · estimates only — the tool lays out the mechanics but a live BIR document needs your registration details and a system-controlled serial. Verify VAT, percentage tax, and EWT treatment against current BIR issuances and with your accountant before issuing.
