The Daily Deduction

Two minutes of tax truth — every number traced to an IRS source. One rule, one deadline or trap, in the time it takes the coffee to pour — written from IRS sources, checked by a credentialed human, and corrected in public when we get one wrong.

The cadence: Weekday mornings during filing season; Mondays the rest of the year. The first issues are below — the list opens with them.

Each issue does one job: a rule worth knowing before it costs you, a deadline that is quietly approaching, or a trap that catches people every season — with the IRS source printed at the foot so you never have to take our word for anything. It is the platform’s teaching, in letter form: plain language, three languages at signup, and no outcome promises, ever.

Education only — not personal tax advice. Personal questions route to a credentialed pro.

Issue No. 4

The Credits Nobody Claims

Every year the IRS offers money that most eligible people never ask for — a deduction hiding under a credit's name, a credit for savers that expires soon, a certificate sitting in a closing drawer. Four of them, with the forms that claim them.
