AAC Tax Code.

The National Internal Revenue Code of 1997 as it currently stands — consolidated by the firm to carry the TRAIN Law, the CREATE Act, the Ease of Paying Taxes Act, the VAT on Digital Services Act, CREATE MORE, the CMEPA and the amendatory laws in force to 1 August 2026, with a footnote at every provision naming the law that changed it.

Text current as at 1 August 2026. This is an unofficial consolidation prepared by the firm and not the official text of the Code. Repealed provisions are kept, struck through, so that references in earlier records stay traceable.
