Year-end tax planning for 2026, in plain English

Most year-end tax moves count for 2026 only if they are finished by Thursday, December 31, 2026. Four short guides cover the dates, the numbers, your timing choices and business moves.

Prepared by Prem Tax and Accounting Corp. Last reviewed November 6, 2026. Figures as of November 6, 2026.

Tax year 2026 is the year you report on the return you file in 2027. Gifts, retirement withdrawals, Roth conversions, equipment and stock sales mostly count for 2026 only if they are finished by Thursday, December 31, 2026. Some payments, such as the fourth estimated tax payment, follow on Friday, January 15, 2027. We write each guide to be read in about three minutes, and every number carries its source and its tax year.

Please read: general information only

This page gives general information and education about current federal and state tax topics, including recent legislation, planning ideas, retirement and annuity rules, and court decisions. It is not tax, legal, accounting, investment, insurance or other professional advice, and it is not a substitute for advice from a qualified CPA, attorney or other adviser who knows your facts. Reading it does not create a CPA-client or any other professional relationship with Prem Tax and Accounting Corp. Prem Tax and Accounting Corp is a CPA firm, not a law firm. It does not sell insurance or investment products, and it does not recommend, rate or sell any annuity, fund or other product. A planning idea, a strategy name or an example here is not a recommendation to take or avoid any action.

Tax rules, thresholds, rates and deadlines change often, and Congress, the IRS, the courts and the states change how they apply them. Guidance on recent legislation is still being issued. We checked the figures against the official sources named on the page on the date shown (last reviewed November 6, 2026), but we do not promise that this page is complete, current or free of errors, and we do not update it the moment a rule changes. Where the rules are unsettled or guidance is still pending we say so. Amounts for a future year are labelled planning figures until the IRS or another agency publishes them. Examples use invented numbers and are for illustration only.

To the fullest extent the law allows, Prem Tax and Accounting Corp and its owners and staff are not responsible for any loss or decision that results from using this page. Links to government and other websites are for convenience and we do not control them.
