About a third of US giving lands in December. The IRS requires a written acknowledgment for gifts of $250 or more, and the postmark sets the gift's tax year.

A gift of $250 or more needs a contemporaneous written acknowledgment before the donor files — five IRS-required elements, or the deduction fails.

Miss the 509(a) support tests and the IRS reclassifies you as a private foundation: 1.39% investment income tax, 10% self-dealing tax, Form 990-PF yearly.

Volunteer hours are worth $0 on your return, but the IRS lets you deduct 14 cents a mile, supplies, and uniforms — and two 2026 changes shrink who benefits.

A "$1 per sale" charity promise makes you a commercial co-venturer in 20+ US states. Register in 7, name the number in every ad, and avoid the IRS UBIT trap.

Section 170(e)(3) lets any business deduct donated food at cost plus half the markup, capped at twice cost — with a 15% net-income limit, a five-year carryover, and a Good Samaritan liability shield.

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.

US donor-advised funds deduct appreciated stock at FMV up to 30% of AGI; private foundations cap lower — IRS rules for owners.

Noncash gifts over $500 require Form 8283 and over $5,000 require a qualified appraisal — and every single gift of $250 or more needs a contemporaneous acknowledgment letter before the return is filed.

Nonprofit thrift store bookkeeping covers the fair value and sold-price methods for donated inventory, IRS Publication 561 receipt thresholds, the roughly 85% volunteer-labor and donated-merchandise UBIT exclusions, and when Form 990-T filing is required.

QCDs up to $111,000 in 2026 let IRA owners 70½+ give directly to charity, satisfy RMDs, and exclude the distribution from income.

Starting in 2026, itemized charitable deductions only count above a 0.5%-of-AGI floor, while the new non-itemizer deduction excludes donor-advised funds. This guide shows small business owners how to respond — bunching several years of giving into one high-income year, donating appreciated stock to avoid capital gains, and using the 60%/30% AGI limits and five-year carryforward around a business sale.
