Every deductible dollar you can document lowers both income tax and the 15.3 percent self-employment tax. This page lists what a small business can write off, the 2026 limits taken straight from IRS Revenue Procedure 2025-32, and the part most owners get wrong: keeping proof. Upload your receipts and AI reads the vendor, date, sales tax, line items, and total from each one, then exports a categorized Excel or CSV deduction log.

Owners rarely lose deductions because the expense was ineligible. They lose them because nobody wrote it down, the receipt faded, or the purchase got buried in a personal card statement. The deduction list below is worth real money only if you can substantiate every line on it.
Reconstructing a year from memory in April catches the big items and misses hundreds of small ones. Supplies, parking, software renewals, and shipping add up to more than most owners expect.
Plenty of published guides still quote a 23 percent QBI deduction that never became law, or the pre-2025 Section 179 cap. Filing off outdated figures costs money in both directions.
Fuel, hardware, and register receipts print on paper that fades within months. A deduction backed by a blank slip is a deduction you cannot defend.
The statement shows an amount at a store. It cannot separate the business half of a mixed run from the personal half, and that split is exactly what a deduction depends on.
ReceiptOCR is the capture layer under your write offs. Upload receipts as they arrive or in monthly batches, and the AI returns a categorized spreadsheet with every field extracted, so claiming a deduction becomes reading a row instead of hunting for paper.
Supplies, advertising, travel, meals, software, fuel, and repairs are tagged as each receipt is read, so your log totals by deduction category rather than sitting as one flat list.
Individual items come back in their own columns, which is how a mixed purchase separates cleanly into the deductible part and the personal part.
Sum the log any time and you know real taxable profit before an estimated payment is due, instead of guessing off gross revenue four times a year.
Photograph a thermal receipt at the register and the data is permanent. The IRS accepts legible digital copies as records.
Upload a folder of months of receipts at once. Batch extraction is what makes catching up on a neglected year realistic rather than theoretical.
Export Excel or CSV, hand it to your accountant, drop it in your own template, or import it into bookkeeping software. No per-seat fee to keep reading your own records.
The list only pays out if the documentation holds. This is the shortest workflow that keeps it complete.
Run every business purchase through a dedicated account and card. It is the single change that makes the rest of this easy, because business and personal costs never mix in the first place.
Tip: Do this even as a sole proprietor. You do not need an LLC to open a second checking account, and the clean paper trail is worth far more than the paperwork it costs.
Photograph paper receipts at the register, route emailed ones into a single folder, and upload the batch once a month. The AI reads vendor, date, line items, sales tax, and total, and assigns a category.
Download the Excel or CSV log, review the rows, and carry category totals onto Schedule C or hand the file to your CPA. Every number on the return now has a receipt behind it.
Written for US sole proprietors, single-member LLCs, partnerships, S corporations, freelancers, and contractors filing Schedule C or a business return, who want the full deduction list and a record that survives questions.
Filing Schedule C, paying self-employment tax, and deducting home office, vehicle, supplies, software, and professional fees against business income.
Contractors, cleaners, stylists, and mobile services writing off tools, materials, vehicles, licensing, and insurance across a busy year.
Product businesses that must split cost of goods sold in Part III from operating expenses in Part II, and track platform fees, shipping, and packaging.
Professionals who receive a client folder of receipt images and need it as a categorized spreadsheet instead of a stack to key in by hand.
Last updated July 2026. Every dollar figure below is taken from IRS Revenue Procedure 2025-32 and current IRS guidance, not from secondary summaries.
A small business can write off any expense that is both ordinary and necessary for the business, meaning common in your trade and helpful to running it. In practice that covers supplies, equipment, software, advertising, vehicle costs, business travel, half of business meals, home office, insurance, licenses, contract labor, professional fees, and interest on business debt. Personal costs, commuting to a regular workplace, political contributions, and fines are not deductible.
The categories below map to where they actually land on Schedule C, which is the part most deduction lists leave out.
| Write off category | Typical examples | Schedule C location |
|---|---|---|
| Advertising | Ads, website, print, branded materials | Line 8 |
| Vehicle expenses | Business mileage or actual costs, tolls, parking | Line 9 (Part IV) |
| Contract labor | Subcontractors and 1099 workers | Line 11 |
| Depreciation and Section 179 | Equipment, machinery, furniture, vehicles | Line 13 (Form 4562) |
| Insurance | Liability, property, business auto | Line 15 |
| Interest | Business loan and business card interest | Line 16 |
| Legal and professional | Attorney, CPA, bookkeeping fees | Line 17 |
| Office expense | Software, postage, office supplies | Line 18 |
| Rent or lease | Workspace, equipment, vehicle leases | Lines 20a and 20b |
| Repairs and maintenance | Tool and equipment servicing | Line 21 |
| Supplies and materials | Consumables used in the work | Line 22 |
| Taxes and licenses | Permits, business licenses, employer taxes | Line 23 |
| Travel | Airfare, lodging, rental cars for business trips | Line 24a |
| Business meals | 50 percent of qualifying meals | Line 24b |
| Utilities and phone | Business share of service | Line 25 |
| Cost of goods sold | Inventory, raw materials, direct labor | Part III |
| Home office | Simplified or actual-expense method | Line 30 (Form 8829) |
Anything that does not fit a named line goes on line 27a as an other expense, and each type has to be named and totaled in Part V rather than lumped into a single figure. Our Schedule C expense tracker covers that line mapping in more detail.
These are the numbers that changed, verified against IRS Revenue Procedure 2025-32 and IRS guidance. A large share of the deduction guides published this year still quote superseded figures.
| 2026 rule | Amount | What it means for you |
|---|---|---|
| Section 179 expensing limit | $2,560,000 | Deduct qualifying equipment and off-the-shelf software in full the year it is placed in service |
| Section 179 phase-out threshold | $4,090,000 | The limit shrinks dollar for dollar once purchases pass this figure |
| Section 179 SUV cap | $32,000 | The ceiling on any single sport utility vehicle expensed under Section 179 |
| Bonus depreciation | 100 percent | Permanently restored by the OBBBA for qualifying property placed in service after January 19, 2025 |
| QBI deduction rate | 20 percent | Still 20 percent. The 23 percent figure circulating online came from a proposal that did not become law |
| QBI minimum deduction | $400 | New for tax years beginning after 2025, if you have at least $1,000 of qualified business income |
| QBI threshold amount | $201,750 single, $403,500 joint | Below this, the wage and property limits and the SSTB restriction do not apply |
| Standard mileage rate | 72.5 cents per mile | The alternative to tracking actual vehicle costs |
| 1099-NEC filing threshold | $2,000 | Raised from $600 for payments made after December 31, 2025, the first change since 1954 |
| 1099-K threshold | Over $20,000 and over 200 transactions | Reverted from the lower proposed level |
| Business meals | 50 percent | Unchanged, and the receipt still needs the business purpose recorded |
A write off reduces taxable income, not your tax bill directly. If your business nets $80,000 and you document $15,000 of deductible expenses, you are taxed on $65,000. The saving equals the expense multiplied by your marginal rate, and for self-employed filers it also cuts the 15.3 percent self-employment tax on that income, so the combined effect is usually far larger than owners assume.
That is also why the recordkeeping matters more than the list. A deduction you can name but cannot document is one you either skip or cannot defend, and the burden of proof sits with you rather than the IRS.
By dollar value, the largest deductions for most small businesses are equipment purchases expensed under Section 179 or bonus depreciation, vehicle costs, the home office deduction, health insurance premiums for the self-employed, retirement plan contributions, and the qualified business income deduction. Those six move the number more than any amount of careful supply tracking, but the small recurring costs are what quietly add up over twelve months.
Yes, for the business-use portion. You choose between the standard mileage rate of 72.5 cents per mile for 2026 and the actual-expense method covering gas, insurance, repairs, and depreciation. You cannot claim both on the same vehicle, and you generally have to pick the standard rate in the first business year of the car to keep the option open later. Tolls and parking are deductible under either method. Commuting between home and a regular workplace is never deductible.
Usually yes, if the space qualifies. It has to be used regularly and exclusively for business. The simplified method gives $5 per square foot up to 300 square feet, capping at $1,500 with almost no recordkeeping. The actual-expense method prorates rent or mortgage interest, utilities, insurance, and repairs by the business percentage of your home, and usually produces a larger deduction if your housing costs are high.
Keep proof for every expense you claim, showing the amount, date, vendor, and business purpose. Receipts are the strongest evidence because they show what was actually bought, which a bank or card statement cannot. The IRS accepts electronic copies as long as they are complete, accurate, and legible, so a scanned archive is both valid and easier to search. Keep records at least three years from filing, and six to seven years where a loss or substantial understatement is involved.
Records for depreciable property such as vehicles, machinery, and furniture should be kept for as long as you own the asset plus the normal period afterward, because the original purchase price sets your basis. A tax deduction tracker that stores the extracted data alongside the image solves the retention problem and the search problem at the same time.
Sometimes, but from a weaker position. Bank records, invoices, contracts, and contemporaneous notes can support an expense, and small incidental costs may be reasonable to estimate. Travel, meals, and vehicle expenses carry stricter substantiation rules than ordinary supplies. Anything material is worth documenting properly, because the difference between a claimed deduction and a defended one is the paperwork behind it.
Use a dedicated business account, capture a receipt for every purchase, and convert that pile into categorized rows on a monthly rhythm. The account separation stops mixing, the receipts supply the substantiation, and the monthly batch stops the backlog from ever reaching a full year. That combination is what makes quarterly estimated payments a calculation rather than a guess. A self-employed expense tracker handles the same workflow across multiple income sources.
Deduction lists also vary by trade more than most guides admit. A stylist, a contractor, and a delivery driver claim genuinely different things, which is why our trade guides such as tax deductions for nail technicians and tax deductions for construction contractors go line by line rather than repeating a generic list.
Any expense that is ordinary and necessary for the business. That covers supplies, equipment, software, advertising, business vehicle use, travel, half of business meals, home office, insurance, licenses, contract labor, professional fees, and business loan interest. Personal costs, commuting, political contributions, and fines are excluded no matter how the payment was made.
There is no overall cap on ordinary operating expenses. Specific provisions do have limits: Section 179 expensing tops out at $2,560,000 for 2026 and starts phasing out above $4,090,000 of purchases, and the simplified home office method caps at $1,500. Everything else is limited only by what you actually spent and documented.
It is 20 percent. The 23 percent figure appeared in a proposal that was not enacted, so guides quoting it are wrong. The OBBBA did make the deduction permanent, added a $400 minimum deduction for anyone with at least $1,000 of qualified business income, and set the 2026 threshold amounts at $201,750 for single filers and $403,500 for joint filers.
No. Deductions follow business activity, not entity type. A sole proprietor filing Schedule C claims the same ordinary and necessary expenses an LLC does. An LLC can offer liability protection and different tax elections, but forming one does not by itself create or increase a single deduction.
Both let you deduct asset costs up front. Section 179 is elective per asset, capped at $2,560,000 for 2026, phases out above $4,090,000 of purchases, and cannot create a business loss. Bonus depreciation is 100 percent, applies automatically to whole asset classes unless you opt out, has no dollar cap, and can create a loss.
Yes, as startup costs. You can generally deduct up to $5,000 of startup expenses and $5,000 of organizational costs in the first year, with both amounts reduced once total costs exceed $50,000, and amortize the remainder over 180 months. Keep those early receipts, because they are the ones owners most often throw away.
At least three years from the date you file, which covers the ordinary audit window. Extend to six or seven years for a loss carryforward, a bad debt, or a substantial understatement of income. Records for depreciable assets should be kept for as long as you own the property plus the normal period after disposal, because they establish your basis.
Yes. The IRS accepts electronic copies of receipts provided they are complete, accurate, legible, and retrievable. Photographing a receipt at the register is the safest option for thermal paper, which fades to blank within months. Store the extracted data alongside the image so the record stays searchable years later.
No, and it is not meant to. Clean categorized records make an accountant faster and cheaper because they spend the engagement on tax positions instead of sorting your paperwork. Most small businesses get more value from a CPA when they arrive with a complete expense log than from any amount of software alone.
