Start year-end tax prep in October: collect W-9s under the IRS $2,000 1099 rule, clean up vendors, reconcile Q3, and calendar every deadline.

Got a 1099 for income that isn't yours? File a nominee 1099 and Form 1096, then subtract the pass-through on Schedule B or C to avoid a CP2000.

The IRS raised the 2026 business mileage rate from 72.5 to 76 cents for miles driven from July 1 — date every log entry or you cannot prove the higher rate.

Two employers over-withheld? Claim excess Social Security tax on Schedule 3, Line 11; a single employer's error needs a W-2c and Form 843 instead.

IRS TIN Matching is free and catches name/TIN mismatches before you file 1099s — each bad return can cost up to $340 plus 24% backup withholding.

IRS Free File is open to AGI of $89,000 or less for 2026, and Direct File is gone. Start at IRS.gov or your free return quietly becomes a paid one.

Form 1098 Box 1 goes to Schedule E line 12 and Box 5 to line 9, but rental points must be amortized over the loan term — never expensed in year one.

IRS-certified VITA and TCE volunteers file federal returns for $0 — VITA at roughly $69,000 income or less, TCE at age 60+ with no income cap.

Item L reports tax-basis capital, not your outside basis — the IRS excludes partnership debt, so a negative ending balance is usually arithmetic, not alarm.

IRS Form 3911 traces a missing refund after 5 days for direct deposit or 4–9 weeks for paper checks; BFS then cancels the original or investigates the forgery.

Notice CP59 means the IRS has no record of your prior-year return. File the missing return, show you already filed, or explain on Form 15103 why none is due — and file your own return before the IRS prepares a substitute one without your deductions.

A PTIN, an EFIN after a 45-day IRS suitability check, and Form 8867 diligence on every credit return — the federal startup checklist for paid preparers.
