- App support (login issues, DAT file errors, certificate generation problems): use the email above, or check the relevant module in the app for in-app guidance first.
- Tax or filing advice: BIR Online Tools and this blog provide general information only, not personalized tax advice. For advice specific to your situation, consult a qualified tax professional — see our disclaimer on every article.
- Content corrections: if you spot an outdated rate, threshold, or regulation reference in a blog post, email us the post URL and the correction — we review and update cited figures as regulations change.
