If you work for yourself, you pay tax on your profit, not on what clients pay you. Every ordinary and necessary business expense you deduct on Schedule C lowers that profit, and a lower profit means less income tax and less self-employment tax. This guide goes through the expense lines in the order they appear on the form, with examples that fit freelancers, then covers the year-end purchases that can still count for 2026, a worked example at $80,000 of revenue, and the deductions that cause trouble in an audit. To see what your own numbers would do, use the freelance tax calculator.
What counts as a business expense
The IRS test in Publication 334 is that an expense must be ordinary and necessary. Ordinary means common and accepted in your line of work. Necessary means helpful and appropriate for your business; it doesn’t have to be indispensable. If an expense is partly personal, you separate the personal part, and only the business part is deductible.
The IRS used to point to Publication 535 for the long version of these rules. Publication 334 now says that Publication 535 has been discontinued, so the sources here are the Schedule C instructions and Publication 334, chapter 8.
Schedule C, line by line
These line numbers are from the 2025 Schedule C, the current form as I write this. The IRS hasn’t published a 2026 version, so check the numbers when it does. One change worth knowing: line 27a is now used for the energy efficient commercial buildings deduction, and “other expenses” moved to line 27b.

Line numbers from the 2025 Schedule C and its instructions. Examples are ours; the IRS lists the categories in the Schedule C instructions and Publication 334, chapter 8.

A few of these lines deserve more than a table cell.
Contract labor and the 1099 rule
If you pay a subcontractor, you may have to file Form 1099-NEC. The IRS says the reporting threshold is $600 for payments made before 2026 and $2,000 for payments made in 2026, with an inflation adjustment for later years. Schedule C also asks near the top whether you made payments that would require 1099s and whether you filed them. Collect a W-9 before you pay anyone, because it’s much easier than chasing it in January. The 1099-NEC vs. 1099-K guide covers the deadlines, penalties and what to do when a form is wrong.
Software, subscriptions and equipment
The Schedule C instructions say you can deduct technology and software tools that are ordinary and necessary for the business, such as the subscription services you pay to manage it. They also say that most computer software costs have to be capitalized and depreciated or expensed under Section 179, and that anything which must be depreciated or amortized doesn’t go in as an ordinary expense. In practice: a monthly design or accounting subscription goes on line 27b, and a laptop goes through line 13.
Startup costs
If your business began this year, you can elect to deduct up to $5,000 of certain startup costs. That limit shrinks by the amount your total startup costs exceed $50,000, and what’s left is amortized over 180 months starting the month the business began. Most freelancers who start with a laptop and a website are well under the limit.
Travel, meals and gifts
Travel means overnight trips away from your tax home, which for most people is the main place of business. The Schedule C instructions state that you can’t deduct employment away from home that lasts more than a year, and that travel for your spouse or others isn’t deductible unless that person is your employee and the travel has a business purpose.
Meals are deductible at 50%, never 100%. Publication 463 says you can’t deduct any expense related to entertainment, amusement or recreation, and that business meals stay 50% deductible if you or your employee is present and they aren’t lavish or extravagant. The meal has to be provided to a current or potential client, customer, consultant or similar business contact. A business gift is limited to $25 per person per year.
If you work long assignments away from home, as locum clinicians and contract nurses do, the tax home guide for locum tenens and 1099 nurses explains when lodging and meals count.
Year-end 2026: what to buy before December 31
The cash method most freelancers use counts an expense in the year you pay it. Equipment adds two rules on top of that, and 2025’s tax law changed them, so it’s worth checking before you shop.
| Rule | 2026 figure | Source |
|---|---|---|
| Section 179 maximum deduction | $2,560,000 | Rev. Proc. 2025-32 |
| Section 179 phase-out starts when equipment placed in service exceeds | $4,090,000 | Rev. Proc. 2025-32 |
| Section 179 cap for a sport utility vehicle | $32,000 | Rev. Proc. 2025-32 |
| Bonus depreciation, qualified property acquired and placed in service after January 19, 2025 | 100% | Form 4562 instructions |
| De minimis safe harbor, per item or invoice (no financial statement) | $2,500 | Schedule C instructions |

Section 179 amounts are for taxable years beginning in 2026. The One Big Beautiful Bill Act (Public Law 119-21) raised the 2025 limit to $2,500,000 with a $4,000,000 phase-out and reinstated 100% bonus depreciation.
Section 179 lets you deduct the cost of qualifying equipment in the year you place it in service instead of spreading it over several years. The Form 4562 instructions add that the property must be used more than 50% in your business, and that the deduction can’t exceed your taxable income from the active conduct of your business, computed before the Section 179 deduction and before the deduction for half of self-employment tax. A freelancer with a small profit can’t use Section 179 to create a loss, though Publication 946 lets the disallowed amount carry to the next year. Bonus depreciation, below, is different on paper: neither Publication 946 nor the Form 4562 instructions attach a business income limit to it. I haven’t found an IRS statement on what that means for a year with little profit, so ask a tax professional before you rely on it to create a loss.
Bonus depreciation is an additional deduction you take after any Section 179 deduction and before regular depreciation. Qualified property includes tangible property with a recovery period of 20 years or less and computer software, new or certain used. For a typical freelancer, the practical result is that computers, cameras and furniture can be fully deducted the year you start using them.
Two smaller options matter more for most people. The de minimis safe harbor lets you deduct items of up to $2,500 per item or invoice if you elect it and deduct them in your books. The amounts go on line 27b as other expenses. And repairs and supplies are deductible without any of this.
Year-end traps
- Placed in service, not bought. Publication 946 says property is placed in service when it is ready and available for its specific use. If the monitor arrives on January 3, it’s a 2027 deduction.
- Prepaying a year. The cash method doesn’t let you deduct everything you pay in advance. Publication 334 gives an example: a $1,000 one-year insurance policy that starts July 1 is deducted half in the year paid and half the next year. The rule is that an advance payment is deductible only in the year it applies to, so an annual plan paid in December is split the same way.
- Buying to save tax. A $2,500 purchase doesn’t save $2,500. On the return in the example below, another $2,500 of equipment saves $576, so you still spend most of it. Buy what the business needs.
- Vehicles. Cars and pickup trucks are listed property under the Schedule C instructions, which means vehicle records, the more-than-50% business use test and recapture if business use falls to 50% or less. Read the mileage guide before buying one for the tax break.
Other year-end moves, like funding a Solo 401(k) or SEP, aren’t Schedule C items. They’re covered below and in Solo 401(k) vs. SEP IRA. If you’d use both plans, see using a SEP IRA and a 401(k) at the same time.
Worked example: $80,000 of revenue
A single freelance designer with no other income and no dependents takes in $80,000 in 2026. Their expenses are realistic for a one-person business and use Schedule C lines only.

The $2,200 laptop could also go on line 27b through the $2,500 de minimis safe harbor, but that route needs its own election, so the example assumes you didn’t make it and used Section 179 on line 13. The deduction is the same $2,200 either way.

Single filer, no other income, 2026 rates and the standard deduction, with half of self-employment tax deducted and the QBI deduction applied. Same function as our freelance tax calculator. State tax not included.
The expenses saved $3,562 of federal tax, about 23 cents for each dollar deducted, and $2,183 of that was self-employment tax. Part of the benefit is offset because a smaller profit also shrinks the QBI deduction: it was $11,650 without the expenses and $8,778 with them. Because the profit is lower, your quarterly estimated payments should be lower too, and how much to set aside depends on the profit, not the revenue.
Deductions that cause problems
Most audits of sole proprietors aren’t about fraud. They’re about records that don’t prove a legitimate expense, or an expense that is partly personal. These are the four to watch.
Meals. The tests are who was there, why, and whether it was lavish. A receipt that shows the restaurant, the number of people, the date and the amount supports it, per Publication 463, and a note of who you met and why supports the business purpose. If a bill includes entertainment, the food and drink must be stated separately. A solo lunch while you work isn’t a business meal.
Vehicle. Commuting from home to your main workplace is personal. If your home is your principal place of business, driving from home to a client counts. Schedule C asks if you have evidence for the deduction and whether it is written. Publication 463 calls a weekly log a timely record and accepts a representative sample of the year, but a log rebuilt in April is weak. If you claimed the Schedule 1-A deduction for loan interest on the personal share of the vehicle, the instructions say you can’t also deduct that interest on Schedule C.
Home office. The space must be used regularly and exclusively for business. A desk in the living room fails. The home office guide compares the two methods with a worked example, and the home office calculator runs your numbers.
Mixed personal and business use. Phones, internet, laptops, software and cars are the usual ones. The rule is the same: deduct the business share, and have a reason for the percentage. A separate business bank account and card make the split much easier to defend. Nothing in the rules requires one, but it turns a year of guessing into a statement you can read.

Records to keep
Publication 463 says to keep adequate records: an account book or log, plus documentary evidence such as receipts, canceled checks or bills that show the amount, date, place and essential character of the expense. Record it at or near the time it happens. For expenses under $75 other than lodging, documentary evidence isn’t required, but the record of the elements still is.
How long to keep them depends on the item. The IRS says three years from the date you filed your original return, or two years from the date you paid the tax if that is later, in the simple case. It is seven years if you claim a bad debt deduction and six years if you left out more than 25% of the income on your return. The IRS says to keep records as long as needed to prove the income or deductions on a return, so equipment receipts belong in the same folder for as long as you claim depreciation on them. A folder per year is enough: 1099s, bank and card statements, receipts, the mileage log and your depreciation schedule.
What does not go on Schedule C
Three of the biggest deductions for self-employed people aren’t business expenses at all. They’re adjustments to income on Schedule 1 (Form 1040), which lower income tax but not self-employment tax.
| Deduction | Where | Guide |
|---|---|---|
| Half of your self-employment tax | Schedule 1, line 15 | Self-employment tax explained |
| SEP, SIMPLE or Solo 401(k) contributions for yourself | Schedule 1, line 16 | Solo 401(k) vs. SEP IRA |
| Self-employed health insurance | Schedule 1, line 17 | Health insurance deduction |
| HSA contributions | Schedule 1, line 13 | HSA for the self-employed |

Each has its own guide: self-employment tax, Solo 401(k) vs. SEP IRA, the health insurance deduction and the HSA guide. Line 19 of Schedule C, pension and profit-sharing plans, is for contributions you make for employees. Your own contributions don’t go there.
Some things aren’t deductible anywhere. Publication 334 lists entertainment, personal and family expenses, fines and penalties paid to a government, charitable contributions and dues to social or athletic clubs among the expenses you usually can’t deduct as business expenses.
What changed with the 2025 law
The One Big Beautiful Bill Act (Public Law 119-21) changed several things that touch a freelancer’s Schedule C. The IRS materials cited here confirm these:
- Section 179 limits went up to $2,500,000 for 2025 and $2,560,000 for 2026.
- 100% bonus depreciation is back for qualified property acquired and placed in service after January 19, 2025.
- The 1099-NEC threshold is $2,000 for payments made in 2026, up from $600.
- The 20% QBI deduction is permanent.
- Domestic research and experimental expenditures can be deducted again in the year paid, or amortized over 60 months or more by election. Whether anything you do qualifies is a question for a tax professional.
Meals stay at 50% and entertainment stays nondeductible.
How we got these figures
The line descriptions and examples are from the 2025 Instructions for Schedule C and Publication 334 (2025), the meals, gifts, travel and record rules from Publication 463 (2025), and placed-in-service, listed property and Section 179 rules from Publication 946 and the Form 4562 instructions (all 2025 editions). The 2026 Section 179 figures come from Rev. Proc. 2025-32, and the 1099-NEC threshold from the IRS 1099 page, all of which we opened on October 10, 2026. The Schedule 1 line numbers are from the 2025 form. The example is our own arithmetic, run through the same functions as our freelance tax calculator with a single filer, no other income and no state tax.
