LLC tax write-offs are ordinary and necessary business expenses you deduct from revenue to lower taxable income, including rent, salaries, insurance, marketing, utilities, and startup costs (up to $5,000 initially).

Proper record-keeping, like separating finances and tracking mileage, is crucial for claiming these deductions.
You can deduct these expenses whether you take the standard deduction or itemize:

Many business expenses are 100% deductible, including advertising, employee wages, rent, supplies, and certain business meals like company parties or meals for the public, while personal deductions like student loan interest or charitable donations (depending on the type) can also be fully deductible for individuals. The key is that the expense must be "ordinary and necessary" for your trade or business or meet specific IRS criteria, often differentiating from the 50% rule for client meals.
What does the IRS allow you to deduct (or “write off”) without receipts?

Yes, your LLC can pay for your cell phone, and it's a common way to deduct business expenses, but you must be able to prove the business use, usually by paying for a business line or deducting the business-use percentage of a personal plan, keeping meticulous records of calls/texts/data for work, and ensuring it's a necessary tool for your business to get a tax benefit.

Deductions subtracted from your gross income to calculate your adjusted gross income are known as “Above-the-line” deductions.
The "$1000 instant tax deduction" refers to a proposed Australian tax policy, specifically from the Albanese Labor government in 2025, allowing eligible workers to claim a flat $1,000 deduction for work-related expenses without needing receipts, simplifying tax returns for those with lower expenses but potentially costing those with higher expenses, starting from 1 July 2026. It's an option to replace itemised work-related deductions, not an extra refund, and doesn't affect non-work-related deductions like charity.
The $20,000 limit under the measures applies on a per asset basis, so small businesses can instantly write off multiple assets. Assets valued at $20,000 or more can continue to be placed into the small business pool and depreciated at 15% in the first income year and 30% each income year after that.
The "20k rule" refers to the traditional IRS threshold for reporting income from payment apps and online marketplaces on Form 1099-K: over $20,000 in gross payments AND more than 200 transactions in a calendar year. While a law (the American Rescue Plan) temporarily lowered the threshold to $600, recent legislation, the One Big Beautiful Bill Act (OBBBA) (OBBBA), has reinstated the $20,000/200-transaction rule for tax years starting in 2025, providing relief for casual sellers and gig workers.
For the 2025 tax year, you'll generally receive a Form 1099-K from platforms like eBay, Etsy, and payment apps if you have over $20,000 in gross payments AND more than 200 transactions, but you must report all income (even small amounts) if it's for goods/services, as you're taxed on profit, not just when you get a 1099-K, with lower state thresholds possible.
