A 0.9% surtax applies to earned income above $200,000 (single) or $250,000 (joint), but employers withhold using a flat $200,000 per-job trigger. Form 8959 reconciles the two rules — generating a balance due for most dual-income couples and a credit for over-withheld single earners.
Under the Bipartisan Budget Act centralized audit regime, the IRS assesses partnership tax adjustments at the entity level at the highest individual rate. This guide explains when to elect out under Section 6221(b), how the partnership representative can modify or push out the imputed underpayment under Section 6226, and how to file an administrative adjustment request on Form 8082.

Form 2290 funds federal highway maintenance through an annual excise tax on vehicles with a taxable gross weight of 55,000 pounds or more. Owner-operators and fleets owe up to $550 per truck and must file by August 31 — late filings trigger a 4.5% monthly penalty and DMV registration suspension.
SECURE 2.0 cut the missed-RMD excise tax from 50% to 25%, and to just 10% if the shortfall is corrected within a two-year window. Form 5329 is how taxpayers claim the reduced rate or request a full reasonable-cause waiver, and the form also starts the IRS's three-year limitations clock.
Section 41 lets a qualified small business apply up to $500,000 of R&D credit per year against employer Social Security and Medicare taxes via Form 6765 and Form 8974. This guide explains the QSB tests, the four-part research test, the redesigned Section G that becomes mandatory in 2026, and how OBBBA's Section 174 reset changes the timing math.

A practical walkthrough of Form 941-X — when to use the adjustment process versus the claim process, the three-year (or two-year) statute of limitations, the stricter rules for federal income tax withholding, and what to put on Line 43 so the correction holds up under IRS review.
