The "Hummer Rule" or "Hummer Deduction" refers to a tax provision under Section 179 of the U.S. tax code that allows businesses to immediately deduct the full cost of certain large, heavy vehicles, like SUVs and trucks over 6,000 pounds, as a business expense, rather than depreciating it over time. Originally intended for actual heavy equipment like bulldozers, it became known as the Hummer Rule because Hummers and other large SUVs fit the weight criteria, enabling significant tax write-offs for business use, though rules and limits have since been adjusted.

While the American Rescue Plan initially set this lower threshold for 2022 and beyond, the IRS delayed implementation, keeping the old rule ($20,000 and 200+ transactions) for 2022 and 2023, then phasing in a $5,000 threshold for 2024, before recent legislation reverted the federal threshold back to the old $20,000 and 200+ transactions for 2023 and future years (as of late 2025/early 2026), aiming to reduce confusion.

They also receive income info from banks, employers (W-2s), and other financial institutions, flagging discrepancies if your tax return doesn't match these records, meaning even cash or small amounts can be noticed if reported by others.
