How we read a law for this section
- A provision is one sentence of the law that says a part of a tax law "is amended" or "is repealed". The words are quoted from our saved copy of the law. Words inside text the law inserts into another law are not read as provisions.
- A sentence counts when it names the Internal Revenue Code of 1986 or title 26 of the United States Code; when it says "such Code" and the last Code named in that section of the law is the Internal Revenue Code of 1986; when the law says that its amendments are to be read as amendments to the Internal Revenue Code of 1986 and the sentence names no other law; or when the sentence names no law at all and the amending sentence before it, in the same section of the law, amended the Internal Revenue Code of 1986.
- A sentence that amends the Harmonized Tariff Schedule of the United States or the Tariff Act of 1930 is listed under "Tariffs and customs duties".
- The tax type comes from the number of the Code section the sentence names. Sections 1 to 5, 21 to 26, 32, 35, 36, 36B, 62, 63, 67, 68, 151 to 153 and 211 to 224 apply to individuals: "Individual income tax". Sections 11, 12, 59A, 241 to 250, 301 to 385, 531 to 565 and 1501 to 1564 apply to corporations: "Corporate income tax". Every other section from 1 to 1400Z and 1411 to 1564 is "Income tax, individuals and businesses". Sections 1401 to 1403 and 3101 to 3512: "Payroll taxes". Sections 2001 to 2801: "Estate and gift taxes". Sections 4001 to 5891: "Excise taxes". Every other section, such as the rules on returns, penalties and trust funds: "Other tax law".
- A sentence that names a chapter or subtitle of the Code and no section is sorted by that chapter or subtitle. A sentence that adds a new section is sorted by the new section's number.
- "Old and new" is shown only where the law says both: "striking X and inserting Y". Other dollar amounts and percentages in the sentence are listed as printed.
- A change to a table of contents or a change headed "Conforming" or "Clerical" is listed apart.
- A law reads "This law changes no tax" only when our saved copy reaches the end of the law, no sentence above is found, the text does not name the Internal Revenue Code of 1986, the Internal Revenue Service, the Harmonized Tariff Schedule of the United States, a tariff, a duty or a named tax, and the margin of the official print cites title 26 of the United States Code nowhere.
- Nothing here says how much tax anyone pays. That takes figures the law's text does not state.
