Quick answers on forms, DAT validation, certificates, and accreditation.
Pointers into the detailed BIR docs.

Which BIR forms does eKapital support?

See the full list in Forms & templates — VAT, percentage tax, withholding (monthly/quarterly/annual), income tax, and certificates.

Can I edit a DAT file by hand?

No. DAT files follow BIR Alphalist v7.4 byte-for-byte, and hand edits break the checks BIR’s own validation module runs (rate conventions, totals cross-checks). Regenerate from your data instead.

Why is my rate showing as `10.00` in the DAT but `0.10` in the app?

They’re the same rate in two prescribed representations: the app shows rates as fractions (0.10), while BIR’s DAT format requires whole-percent (10.00). The export converts for you — never hand-adjust it.

Are the form samples in these docs real?

No. Every sample is labelled “Mock example — do not submit” with placeholder/redacted TINs and names.

Is eKapital CAS-accredited?

CAS readiness is built in — the books of accounts, prescribed headers, and audit export the BIR expects. See Recordkeeping & audit.

How are 2316/2307 certificates delivered?

PDF by email attachment by default; a signed, revocable public share-link serves 2307 download and 2316 e-sign without a login. See Withholding tax.
