Section 199A QBI Aggregation Election Under Reg 1.199A-4: How Pass-Through Owners Combine Commonly Controlled Trades or Businesses to Beat the W-2 Wage and UBIA Limits
The Section 199A aggregation election under Reg 1.199A-4 lets pass-through owners combine commonly controlled trades or businesses before applying the W-2 wage and UBIA of qualified property limitation. This guide walks through the five eligibility tests, the Form 8995-A Schedule B disclosure, the irrevocable consistency rule, and when pooling QBI across an operating-and-leasing or multi-entity structure actually unlocks more deduction.
Form 8995 vs. Form 8995-A: Choosing the Right QBI Form for 2026
Form 8995 is a one-page worksheet; Form 8995-A is a four-part return with four schedules. The line between them in 2026 is $403,500 for joint filers and $201,750 for everyone else — and crossing it adds W-2 wage limits, SSTB phase-outs, and aggregation math to the return.
The Self-Employed Health Insurance Deduction: How Section 162(l) Beats Itemizing
Section 162(l) lets sole proprietors, partners, and more-than-2% S-corp shareholders deduct health, dental, vision, LTC, and Medicare premiums above the line on Schedule 1, line 17 — bypassing the 7.5%-of-AGI floor that gates itemized medical deductions. Form 7206 enforces three limits — earned income, subsidized-coverage months, and PTC coordination — and S-corp owners must include premiums in W-2 Box 1 (not Box 3 or 5) to preserve the deduction.
Additional Medicare Tax 0.9%: How Form 8959 Reconciles Employer Withholding With Filing Status Thresholds
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.
Form W-2c and W-3c: How to Correct a W-2 Without Triggering Penalty Cliffs
Form W-2c fixes errors on previously filed W-2s, but the penalty structure stacks behind the original February 2 due date — $60, $130, $340, or $680 per form depending on how late you file. A practical guide to W-2c and W-3c filing, the 10-return e-file threshold, SSA mismatch letters, and reconciling with Form 941-X.
Section 79 Group-Term Life Insurance: The $50,000 Tax-Free Limit, IRS Table I, and W-2 Code C
How Section 79 actually works in 2026 — the $50,000 employer-paid group-term life exclusion, the IRS Table I rates (unchanged since 1999) that turn excess coverage into W-2 Box 12 Code C imputed income, plus the straddle rule, the $2,000 dependent de minimis, and the 2% S-corp shareholder trap.
OBBBA No Tax on Overtime: How the New $12,500 Deduction for FLSA Premium Pay Works Through 2028
The One Big Beautiful Bill Act creates an above-the-line deduction of up to $12,500 ($25,000 joint) on FLSA-required overtime premium pay for tax years 2025-2028, with a MAGI phase-out starting at $150,000 single and mandatory W-2 Box 12 Code TT reporting from 2026.
W-2 vs W-4: The Two Tax Forms Every Employee and Employer Must Know
A practical comparison of Form W-4 (the withholding certificate employees give employers) and Form W-2 (the year-end wage statement employers send the IRS), with 2026 OBBBA updates—$2,200 Child Tax Credit, qualified tips and overtime deductions—and the filing mistakes that quietly cost workers refunds.
