Tax Digest


New product

A good number of tax laws had been passed since the last edition of this material. Republic Act No. 9337 introduced significant amendments to income taxation and mercantile taxes such as the value-added tax, percentage taxes and excise taxes. Republic Act No. 9243 likewise refined the law on documentary stamp taxes. Republic Act No. 9282, together with the Revised Rules of the Court of Tax Appeals, expanded the jurisdiction of the tax court. And finally, Republic Act No. 9504 radically amended the income taxation in the country by providing for bigger amounts of personal and additional exemptions, and its shift to a more favorable optional standard deduction and the exemption of statutory minimum wage earners from income tax are a welcome relief to the lower economic bracket of our society.

This edition also enhanced the discussion on mercantile taxes and local taxation. Furthermore, the exercises were reasonably increased with relevant Supreme Court decisions and the author’s own theoretical exercises without sacrificing, however, the straight forward and simplistic approach adopted by the previous editions. The Revised Rules of the Court of Tax Appeals (CTA) is appended for easy reference, and an Evaluation Exercise is provided so that the candidate may conduct an appraisal of his knowledge in Taxation before tackling the Bar examinations.
