S Corporation tax strategies, payroll, and accounting requirements
An accrual-basis employer can deduct year-end bonuses in the year earned only if employees actually receive the money within 2½ months after year-end — March 15 for calendar-year businesses. The deduction also requires a liability fixed by December 31 under the all-events test, and it fails for bonuses owed to related parties under Section 267 regardless of payment timing.
Since 2005, the IRS has limited most vehicle donation deductions to the charity's actual sale proceeds reported on Form 1098-C — not Blue Book value. This guide covers the $500 and $5,000 paperwork thresholds, the three exceptions that allow full fair market value, and why a fully depreciated work truck can produce a $0 deduction plus taxable recapture income.
USDA's June 2026 final rule lets farm LLCs and S corporations claim one ARC/PLC payment limit per actively engaged owner — up to $164,000 per person for 2026 — but only if entity structure, per-member contributions, and farm/non-farm income splits are documented with FSA by September 15, 2026. Here's the bookkeeping that proves it.
For tax years starting in 2026, OBBBA makes the 20% qualified business income deduction permanent, widens the married-joint phase-in range to $394,600–$544,600, and adds a $400 minimum for taxpayers with more than $1,000 of QBI — so a $1,500 profit yields $400 instead of $300.
The IRS requires S-corp and C-corp Designated Officials to revalidate Business Tax Account access every June 15 through July 29 or lose online access to payments, transcripts, and notices until they reapply from scratch.
Starting January 1, 2026, anyone whose 2025 FICA wages exceeded $150,000 must direct their entire 401(k) catch-up contribution — $8,000 standard or $11,250 for ages 60-63 — into a Roth account, with no pre-tax option and no opt-out.
Tax liability insurance transfers one specific, identified tax risk — an invalid S-corp election, a Section 382 NOL limit, QSBS eligibility — to an insurer instead of a price cut, escrow, or seller indemnity. Premiums run 2–5% of the insured limit, underwriting takes two to four weeks, and most carriers want exposure above roughly $1 million. Here's how it works and when to raise it before a closing deadline.
An LLC pays 15.3% self-employment tax on all profit; an S-Corp election (Form 2553) splits income into salary and distributions, typically saving $7,000+ once net profit clears $40,000–$60,000. Here's how all three structures compare — and how to switch later.
House flippers are almost always IRS "dealers," not investors — flip profits are ordinary income on Schedule C plus 15.3% self-employment tax, often a combined rate over 40% versus the 15–20% capital gains rate flippers expect. How the Winthrop factors decide dealer status, why rehab costs must be capitalized into COGS, and four strategies (including an S corp election) that reduce the hit.
Maine's 2% surtax on taxable income above $1 million ($1.5 million joint) took effect January 1, 2026, alongside a new pass-through entity tax election at 7.15% with a 90% refundable owner credit. Here's who owes the surtax, how the PTET election interacts with it, and why the two must be modeled together.
Connecticut's Public Act 26-68, signed May 26, 2026, gives pass-through entities — LLCs, S corps, and partnerships with gross income under $70 million — a 6% R&D tax credit for the first time, refundable at 65% (90% for biotech), capped at $1.5 million per business and $25 million statewide, and claimed through a DECD voucher within 90 days of year-end.
In Goodwill-Oikerhe v. Commissioner, a tax preparer lost every disputed deduction — dependents, property tax, vehicle expenses, S-corp flow-throughs — and drew a 75% civil fraud penalty under Section 6663, largely because no records existed. Why the Cohan rule couldn't rescue him, and what contemporaneous bookkeeping must capture to survive an audit.
