Current Topics

Recent tax cases and rulings, in plain English

A court case can change how a tax rule works, but only for the courts and people it reaches. These guides explain how to read a case, list the decisions that matter most and turn them into habits.

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

Tax cases make headlines, but each one reaches only so far. A Supreme Court opinion binds every federal court. A court of appeals opinion binds courts in one region. Many Tax Court opinions simply apply settled law to one family's facts. Our three short guides help you sort them out. We list only decisions we read on the official court or IRS site, and we say when a case is still on appeal or may be reviewed. We never predict what a court will do next.

Through the Supreme Court's orders of November 5, 2026, we found no federal tax case among those it has agreed to hear for its term that began in October 2026. We checked by case name. For how the IRS explains new rules, see our guide to IRS gaps and open questions, and for ways to follow changes, see tracking tax changes.

Common questions

Is a case summary here advice for my situation?

No. Each summary states what a court decided in that case. Your facts, your state and your court may differ, so ask a qualified adviser before you act.

Why are only some cases listed?

We include only decisions we opened on the court's own website and checked against the opinion. Items we could not read ourselves are left out.

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.
