Updated November 8, 2026. Quick answer: An independent consultant’s deductions are mostly travel, a home or rented office, insurance, contract help and professional fees. The rules that matter most are the ones around travel to clients: which place is your tax home, when an assignment counts as temporary, and the 50% limit on meals. Entertainment is not deductible.
The deductions this work usually has to sort out
This page reads the IRS documents linked under Sources, as retrieved on November 8, 2026. The IRS publications and instructions cited here are the 2025 editions, written for returns filed for 2025; check the current edition before relying on a figure.
Every deduction below has to pass one test first. Publication 334 puts it this way: “To be deductible, a business expense must be both ordinary and necessary.” “An ordinary expense is one that is common and accepted in your field of business.” “A necessary expense is one that is helpful and appropriate for your business.” And where a cost is mixed: “If you have an expense that is partly for business and partly personal, separate the personal part from the business part.”
This table is the usual set for consulting work. The line shows where the Schedule C instructions place that kind of cost; whether a particular purchase qualifies is the ordinary-and-necessary question above.
| Cost | Schedule C line | What to keep | Where it is explained |
|---|---|---|---|
| Client travel: air, rail, lodging | Line 24a | Receipts; trip dates, place and business purpose | Schedule C lines 24a and 24b |
| Meals on a trip or with a client | Line 24b | Receipts; who, where, why | business meals records |
| Mileage to client sites | Line 9 | Mileage log with date, miles and purpose | mileage log requirements |
| Subcontractors, researchers, assistants | Line 11 | Invoices and each payee’s Form W-9 | Schedule C lines 10 and 11 |
| Liability insurance | Line 15 | Policy declarations | business insurance for consultants |
| Accountant, attorney, contract review | Line 17 | Invoices | Schedule C lines 17 to 19 |
| Professional licenses and memberships | Line 23 or Part V | Renewal notices | Schedule C line 23 |
| Software, subscriptions, supplies | Line 18, 22 or Part V | Receipts | Schedule C lines 20 to 22 |
Travel to a client: tax home and the one-year line
A consultant’s biggest judgment call is usually travel. Publication 463 says you are traveling away from home if “Your duties require you to be away from the general area of your tax home (defined later) substantially longer than an ordinary day’s work, and” the second condition is “You need to sleep or rest to meet the demands of your work while away from home.” On assignment length: “Generally, a temporary assignment in a single location is one that is realistically expected to last (and does in fact last) for 1 year or less.” The consequence of crossing the line: “if your assignment or job is indefinite, the location of the assignment or job becomes your new tax home and you can’t deduct your travel expenses while there.” The Schedule C instructions repeat the limit for line 24a: “You can’t deduct expenses paid or incurred in connection with employment away from home if that period of employment exceeds 1 year.” Driving between your home and a regular workplace is a different question: “You can’t deduct the costs of driving your car or truck between your home and your main or regular workplace.” but “Visiting clients or customers.” is on Publication 334’s list of local transportation.
Meals and entertainment
Publication 334 states the meal rule for travel: “In most cases, you can deduct only 50% of your meal expenses.” Its list of things you usually cannot deduct as business expenses includes “Entertainment expenses.” Taking a client to a ball game is therefore not a deduction, while the meal portion of a business trip is, at the limited percentage. The records for both are on business meals records. If a client reimburses an expense, how that is reported is on reimbursed client expenses on Schedule C.
The big items
| Big item | How it comes up for this work | Live pages |
|---|---|---|
| Home office | Many consultants work from home. The test is whether the space is your principal place of business: “You use it exclusively and regularly for administrative or management activities of your business.” and you have no other fixed location where you do substantial administrative or management work. | home office records for Form 8829; Schedule C line 30 |
| Vehicle | Client site visits drive the log. The mileage rate and the actual-cost method are alternatives; Publication 334 notes you may compare them, so a year of both records keeps the option open. | mileage log requirements; Schedule C lines 8 and 9 |
| Health insurance | “Do not include on line 14 any contributions you made on your behalf as a self-employed person to an accident and health plan.” The same instructions point you to Schedule 1: “you may be able to deduct on Schedule 1 (Form 1040), line 17, the amount you paid for health insurance on behalf of yourself, your spouse, and dependents, even if you do not itemize your deductions.” | Schedule 1 line 17 |
| Retirement plan for yourself | “If you are a sole proprietor, you can deduct contributions you make to the plan for yourself on line 16 of Schedule 1 (Form 1040).” Plan contributions for employees go on Schedule C line 19, which is why the retirement row sits outside the Schedule C table. | Schedule 1 lines 15 and 16; SEP-IRA contributions |
| Qualified business income | Whether consulting qualifies for the QBI deduction at higher incomes depends on thresholds that change yearly; read the live page for the current numbers. | QBI deduction thresholds for 2026 |
Keeping the records that make these hold up
Publication 463 sets the bar for travel and meals: “You must generally have documentary evidence such as receipts, canceled checks, or bills, to support your expenses.” A consultant on the road is the typical case for a phone-photo workflow, since the receipts arrive in taxis, hotels and airports.
For capture during travel, SparkReceipt’s home page says you can snap a receipt at the counter in the phone app; Dext’s US home page says you can send receipts, invoices and statements by mobile, email, WhatsApp or desktop. These are the vendors’ statements; this page has not used either product. A folder of photographed receipts and a spreadsheet meet the same IRS test, which is whether the record exists and was made close to the time.
Common mistakes
- Treating a long-running client engagement as a temporary assignment. If you expect it to last more than a year, the client site becomes your tax home and travel there stops being deductible.
- Deducting entertainment with a client because the meeting was productive.
- Mixing a personal weekend onto a trip without separating the personal part.
- Paying a subcontractor without collecting a Form W-9 at the start of the engagement.
