Financial management strategies and tools for small business owners
OBBBA permanently restored the EBITDA-based ATI calculation for Section 163(j) starting in 2025, expanding deductible business interest for capital-intensive companies. A guide to the 30% cap, the ~$31M small business exemption, the 35% syndicate trap, EBIE allocations from partnerships, S-corp differences, and Form 8990 reporting.
Section 280E bars cannabis businesses from deducting ordinary expenses, pushing federal effective tax rates past 70%. A walkthrough of the math, the COGS lever under Section 471, key Tax Court rulings (CHAMP, Olive, Harborside), and what 2026 rescheduling could change.
Section 280F caps first-year depreciation on passenger autos at $20,300 in 2026, but SUVs and trucks rated above 6,000 lbs GVWR escape those limits and can combine a $32,000 Section 179 deduction with 100% bonus depreciation. A practical guide to the 2026 numbers, the heavy-vehicle and pickup carve-outs, the 50% business-use cliff, and the mileage-log standards an IRS auditor expects.
Section 530 of the Revenue Act of 1978 eliminates back federal employment taxes on misclassified contractors when small businesses pass three tests — reporting consistency, substantive consistency, and reasonable basis. Revenue Procedure 2025-10 updated the rules in January 2025, the first major change in 40 years.
Section 831(b) microcaptive insurance lets small businesses retain underwriting profit on hard-to-insure risks, but the IRS's 2025 final regulations treat captives with loss ratios under 30% as listed transactions. Here is how to structure one that survives an audit.
A 2026 walkthrough of every small business tax obligation—federal income, self-employment, payroll, sales, and excise—with the full filing calendar, quarterly estimated tax safe harbors, OBBBA-era changes (permanent QBI, $1.21M Section 179, restored 100% bonus depreciation), and the recordkeeping habits that prevent penalties.
A six-week framework for small business owners to catch up unreconciled books, assemble a standardized year-end financial package, and hand off cleanly to an accountant—anchored by the 2026 federal filing deadlines.
OBBBA made the 20% QBI deduction and 100% bonus depreciation permanent for 2026, while tariffs near 19% cost U.S. small businesses about $85 billion a year. Here is what changed, who benefits, and how to plan.
How the IRS uses Internal Revenue Code Section 6672 to hold business owners, officers, bookkeepers, and even spouses personally liable for 100% of unpaid payroll withholdings — covering who qualifies as a responsible person, how willfulness is established, and how to defend a Letter 1153 within the 60-day appeal window.
Form 3115 lets U.S. taxpayers change accounting methods and use a Section 481(a) adjustment to recover missed deductions or correct multi-year errors on a single current-year return, without amending prior years.
How small businesses record foreign exchange gains and losses under US GAAP (ASC 830) and IRC Section 988, with sample journal entries, realized vs. unrealized treatment, period-end revaluation, and a practical monthly close workflow.
Total exposure per misclassified worker now commonly lands between $15,000 and $100,000 once federal back taxes, FLSA back wages with liquidated damages, and state penalties stack. Here is what the 2024 DOL final rule changed, how the IRS and state ABC tests differ, and how Section 530 and the VCSP can cap retroactive liability.
