What expenses can I write off for my LLC?
LLC tax write-offs are ordinary, necessary business expenses that reduce your taxable income, including costs for rent, salaries, marketing, supplies, insurance, and vehicle use, plus specific deductions like the home office, startup costs (up to $5k), and half of self-employment tax for single-member LLCs; meticulous record-keeping is crucial for claiming them.

What is the $2500 expense rule?
The $2,500 expense rule refers to the IRS's De Minimis Safe Harbor Election, allowing small businesses (without an Applicable Financial Statement (AFS)) to immediately deduct the full cost of qualifying tangible property up to $2,500 per item/invoice, instead of depreciating it over years, providing faster tax savings. If a business does have an AFS, the threshold is higher, at $5,000 per item/invoice. This election simplifies accounting for small purchases like computers, furniture, or even home improvements, but requires a consistent bookkeeping process and attaching the specific election statement to your tax return.

100% write-offs allow businesses to deduct the full cost of qualifying assets (like equipment, vehicles, certain improvements) in the first year, significantly reducing taxable income through methods like bonus depreciation or Section 179 expensing, with recent legislation (OBBBA) making 100% bonus depreciation permanent for property acquired after January 2025.

The IRS $600 rule refers to the reporting threshold for third-party payment apps (like PayPal, Venmo, Cash App) for income from goods/services, where they send Form 1099-K to you and the IRS for payments over $600 in a year. 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.
