A guide to state corporate income tax apportionment in 2026 — why 34 of 44 corporate-tax states now use single sales factor, how market-based sourcing rules in California, Kansas, and Arkansas shift SaaS and service company tax bills toward customer location, and five strategies to manage the exposure.
Subpart F forces U.S. shareholders of a controlled foreign corporation to recognize foreign profits as current-year income, even when no cash is distributed. This guide covers the 10 percent threshold, the four triggering income categories, Section 958 constructive ownership traps, Form 5471 penalties, and how the 2026 OBBBA rewrite (NCTI, restored 958(b)(4), 40 percent Section 250 deduction) reshapes the rules.
How U.S. shareholders of foreign corporations are taxed on undistributed profits in 2026: the 10 percent threshold, Section 958 constructive ownership, Form 5471 filing duties, and the OBBBA rewrite that replaced GILTI with Net CFC Tested Income (NCTI).
A practical guide for small employers comparing the three IRS safe harbor 401(k) formulas — basic match, enhanced match, and 3% nonelective — alongside QACA auto-enrollment rules, SECURE 2.0 startup and contribution tax credits, notice deadlines, and the vesting and bookkeeping details that decide whether ADP, ACP, and top-heavy testing actually go away.
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.
The AOTC is worth up to $2,500 per student with $1,000 refundable; the Lifetime Learning Credit caps at $2,000 per return. A 2026 walkthrough of Form 8863 and Form 1098-T covering when each credit wins, the Pell Grant election that unlocks the refundable AOTC, how to coordinate a 529 plan, and the four mistakes that can trigger a 2-to-10-year IRS ban.
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.
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.
Tax year 2026 is the final year for the Saver's Credit, a nonrefundable credit worth up to $1,000 per person ($2,000 MFJ) for IRA and 401(k) contributions. This guide covers the 2026 AGI brackets, Form 8880 line by line, and what changes when the Saver's Match arrives in 2027.
Section 174A restores immediate domestic R&E expensing and lets small businesses with $31 million or less in average annual gross receipts amend 2022, 2023, and 2024 returns for refunds — but the retroactive election must be filed by July 6, 2026.
Section 280G disallows the corporate deduction and imposes a 20% Section 4999 excise tax once parachute payments to a disqualified individual reach three times the executive's five-year average W-2 compensation, with the penalty applying to everything above 1× the base amount. Private companies can eliminate the consequences entirely through a 75% disinterested shareholder vote paired with conditional waivers signed before closing.
