Meet IRS requirements for business tax compliance
The IRS's summer 2026 Business Tax Account update adds a digital notices library, self-service EIN verification letter (CP575) downloads, and online Offer in Compromise payments. Here's who qualifies, how setup works, and why disciplined bookkeeping makes these tools actually useful.
The IRS cut its Enrolled Agent exam fee from $99 to $66 per part in 2026, but new vendor PSI charges $251 versus Prometric's $168 — raising the total to $317 per part. The switch also brings a March–June testing blackout, a 200–800 scoring scale, and first-time remote proctoring for U.S. candidates.
Oral advice from the IRS is not binding — a private letter ruling is. Under Revenue Procedure 2026-1, 9100 relief for a missed tax election generally costs about $14,500, with reduced tiers near $3,450 and $9,775 for smaller organizations, and the IRS must make contact within 21 days of a complete request. Here's when a ruling is worth the fee, what the request must contain, and the no-fee alternatives — Form SS-8, Form 3115, and Rev. Proc. 2013-30 — that cover most common cases.
A safe harbor 401(k) automatically passes IRS ADP/ACP nondiscrimination testing in exchange for a fixed employer contribution — a 3% nonelective or a match of up to 4%. Here's how the three formulas compare in cost, the December 1 retroactive adoption deadline, and the 2026 limits ($24,500 deferral, $72,000 total additions, mandatory Roth catch-ups for high earners).
The "60/40 rule" for splitting S-corp salary and distributions has never appeared in any IRS regulation. What the IRS actually applies is a facts-and-circumstances test — the one that reclassified a CPA's $24,000 salary to $91,044 and cost him $23,000 in back payroll taxes. Here's how to set a defensible number.
Form 8275 lets taxpayers disclose debatable tax positions with the IRS to defeat the 20% Section 6662 accuracy-related penalty when a position has at least a reasonable basis. Covers when to use Form 8275 versus Form 8275-R, what counts as adequate disclosure, timing rules, and Section 6694 preparer-penalty protection.
With the second ERC Voluntary Disclosure Program closed since November 2024, small businesses with overstated Employee Retention Credit claims still have three remedies in 2026: claim withdrawal, self-amendment via Form 941-X, or responding to an IRS recapture letter. The IRS has a six-year audit window open through April 15, 2027 for Q3 and Q4 2021 claims, plus a 20% accuracy-related penalty for erroneous refunds.
Section 531 imposes a 20% accumulated earnings tax on C-corps that retain profits beyond a $250,000 credit ($150,000 for personal service firms) without specific, feasible plans. This guide explains the Bardahl working-capital formula, the Section 534 burden-of-proof statement, and the contemporaneous documentation that defends an accumulation in IRS audit.
A practical walkthrough of how Revenue Procedure 2013-30 lets businesses cure a missed Form 2553 S-corp election within three years and 75 days — no $3,500+ private letter ruling fee, no negotiation, just a checklist and a well-written statement.
A practical guide to Section 469(c)(7) Real Estate Professional Status — the 750-hour and more-than-half tests, the spousal rule, material participation and the grouping election, common audit failures, and how 100% bonus depreciation in 2026 makes REPS worth the documentation cost.
Informal family or employer loans below the AFR trigger IRC Section 7872 imputed interest, treated as gifts, wages, or dividends.
A 409A valuation is the IRS-recognized appraisal that sets the strike price on every option grant. Without one, founders risk 20% federal excise penalties, premium interest, and California's 5% piggyback tax — all falling on the employee.
