Every deduction you miss is money handed straight to the IRS that you didn’t have to give up. Most freelancers know the obvious write-offs — home office, software, a laptop — but plenty of legitimate deductions go unclaimed simply because people don’t realize they qualify. Here are 25 of the most commonly overlooked ones.
As always, a deduction only counts if the expense is ordinary and necessary for your business — keep receipts and records for everything you claim.
Home & Office
1. Home office deduction (simplified or regular method) Many freelancers assume they need a dedicated separate room, but any space used regularly and exclusively for business — even a corner of a room — can qualify.
2. A portion of rent or mortgage interest If you use the regular method for the home office deduction, a percentage of your rent or mortgage interest based on the business-use square footage of your home is deductible.
3. A portion of utilities Electricity, internet, gas, and water can be partially deducted based on the same business-use percentage as your home office.
4. Renter’s or homeowner’s insurance (business-use portion) The percentage of your insurance premium tied to your home office space.
5. Office furniture and equipment Desks, chairs, monitors, filing cabinets — even secondhand purchases count if used for business.
Technology & Software
6. Software subscriptions Design tools, project management apps, accounting software, cloud storage — anything you pay for to run your business.
7. Website hosting and domain fees Your business website’s hosting, domain renewal, and any related maintenance costs.
8. A portion of your phone bill If you use your personal cell phone for client calls, texts, or business apps, the business-use percentage is deductible.
9. External hard drives, cloud backup services, and cybersecurity tools Anything used to protect or back up business data.
10. Stock photos, fonts, and digital assets Purchased licenses for images, fonts, or templates used in client work.
Professional Development
11. Online courses and certifications Courses that maintain or improve skills used in your current freelance work.
12. Books and industry publications Both physical and digital, when relevant to your field.
13. Conference and workshop fees Registration costs for industry events, plus associated travel (see below).
14. Professional membership dues Trade associations, unions, or professional organizations related to your field.
15. Coaching or mentorship fees Business coaching specifically aimed at growing your freelance practice.
Marketing & Client Acquisition
16. Business cards and branded materials Printing costs, branded templates, letterhead.
17. Paid advertising Social media ads, Google Ads, sponsored posts promoting your services.
18. Portfolio or personal website costs Beyond hosting — design fees, premium themes, photography for your portfolio.
19. Networking event fees Tickets or membership costs for local business or industry networking groups.
Travel & Transportation
20. Mileage for business errands Trips to meet clients, pick up supplies, or attend business-related events — not just your «commute» if you have a dedicated workspace elsewhere.
21. Parking and tolls for business trips Often forgotten even when mileage itself is tracked.
22. Airfare, lodging, and 50% of meals for business travel Trips taken primarily for business purposes, including conferences or in-person client meetings.
Financial & Administrative
23. Bank fees on a business account Monthly fees, wire transfer fees, or payment processor fees (Stripe, PayPal, etc.) charged on business transactions.
24. Accounting and bookkeeping software or services Fees paid to a bookkeeper, accountant, or software like an invoicing/accounting platform.
25. Half of your self-employment tax Not a business expense on Schedule C itself, but an «above the line» deduction on your Form 1040 that many new freelancers don’t realize they’re entitled to — it’s calculated automatically on Schedule SE.
A Few Deductions That Deserve Special Mention
Retirement contributions. Contributions to a SEP IRA or Solo 401(k) aren’t listed above because they’re not a Schedule C business expense, but they’re one of the largest deduction opportunities available to freelancers — reducing taxable income while building retirement savings at the same time.
Health insurance premiums. Self-employed individuals who aren’t eligible for an employer-sponsored plan (through a spouse, for example) can often deduct 100% of health insurance premiums for themselves and their family, taken as an adjustment to income rather than a Schedule C expense.
How to Make Sure You Don’t Miss These Next Year
- Use a separate business bank account and card so business expenses are automatically isolated from personal spending, making them far easier to identify at tax time
- Track expenses monthly, not annually — trying to reconstruct a year of receipts in April is how deductions get forgotten
- Use an expense-tracking or accounting app that lets you snap a photo of a receipt and categorize it on the spot
- Review last year’s Schedule C before filing this year’s — it’s a good prompt to check whether you’re claiming everything you claimed before, plus anything new
A Word of Caution
Not every expense that touches your business is fully deductible, and mixing personal use into a deduction (like claiming 100% of a phone bill you also use personally) is a common audit trigger. When in doubt about whether an expense qualifies — or what percentage of a mixed-use expense you can claim — a quick conversation with a tax professional is worth far more than the fee, especially the first year or two of freelancing.
The Bottom Line
Most freelancers focus on the big, obvious deductions and leave smaller ones — a portion of the phone bill, mileage to a client meeting, that industry course from March — unclaimed simply because they weren’t tracked. Building a habit of logging expenses as they happen, rather than scrambling in April, is the single biggest factor in capturing every deduction you’re legitimately owed.
