Maximize tax deductions and reduce your tax liability legally
For most businesses, credit card cash back and points are non-taxable rebates, not income—but a bonus with no spending requirement is taxable. Spending rewards also reduce your deductible expenses, so record them as a contra-expense to keep deductions accurate.
IRS Memorandum AM 2023-004 holds that most nonprofit NIL collectives fail the 501(c)(3) operational test because compensating student-athletes is substantial private benefit, not charitable activity — meaning donor contributions are often not deductible.
The IRS memorandum AM 2023-004 concluded that NIL collectives paying 80-100% of donations to athletes confer substantial private benefit and fail the operational test for 501(c)(3) status, so contributions to them are generally not tax-deductible.
The OBBBA restores a personal car-loan interest deduction—up to $10,000 per year, above-the-line, for tax years 2025 through 2028—on new U.S.-assembled vehicles financed after December 31, 2024. Mechanics covered include the MAGI phase-out starting at $100K single / $200K joint, Form 1098-VLI reporting beginning in 2026, mandatory VIN entry on Form 1040, and edge cases for refinances, trade-ins, leases, and co-signers.
OBBBA raised the SALT deduction cap to $40,400 for 2026, but a 30-cent-per-dollar MAGI phase-down between $505,000 and $606,333 creates a roughly 45% effective marginal rate — the "SALT torpedo." Here is how to decide whether to re-itemize.
Section 1341 lets a taxpayer who repays more than $3,000 of previously taxed income recover the tax cost—via a deduction or a credit, whichever is lower—on the repayment-year return rather than by amending the old one.
Section 7508A lets the IRS postpone tax deadlines up to one year for taxpayers in federally declared disaster counties—usually automatically by address. A Section 165(i) election can also move a casualty loss to the prior year's return for a faster refund.
How partnerships and S corporations in 36+ states use the Pass-Through Entity Tax election under IRS Notice 2020-75 to deduct state income tax at the entity level and bypass the federal SALT cap — with a worked example, resident-credit mechanics, and 2026 election deadlines.
Section 163(h) decides whether your largest Schedule A line is a $14,000 deduction or an $8,500 one. Here is how the permanent $750,000 TCJA cap, the grandfathered $1 million pre-2018 loans, the HELOC "substantial improvement" rule, and the 2026 return of the mortgage insurance premium deduction actually work — with worked examples and the records you need on audit.
Section 163(j) caps the business interest deduction at 30% of adjusted taxable income, and OBBBA restored the EBITDA-style add-back for tax years beginning after December 31, 2024. This guide walks through the calculation, the small business exemption under Section 448(c), the irrevocable real property trade or business election, the partnership EBIE basis trap, and the Form 8990 reporting choreography.
Section 195 and Section 248 let founders deduct the first $5,000 of startup costs and the first $5,000 of organizational costs in year one, with the remainder amortized over 180 months. A guide to the $50,000 phase-out, the deemed election, and the mistakes that forfeit the deduction for LLCs, partnerships, and corporations.
A working guide to Section 274's four meal deduction rates—100%, 80%, 50%, and zero—and the 2026 Section 274(o) cliff that ended the employer deduction for breakroom snacks, catered office lunches, and convenience-of-employer meals.
