Everyday Tools and Software
Anything you pay for to design, build, or deliver client work is deductible on Schedule C. This includes Adobe Creative Cloud, Figma, Webflow, WordPress plugins, Sketch, font licenses, stock photo or icon subscriptions, and project management tools like Asana or Notion. If you pay monthly for it and use it for client work, keep the receipt or bank statement and write it off.
Hardware counts too. A new laptop, external monitor, graphics tablet, keyboard, mouse, or backup hard drive is deductible. If the equipment is used partly for personal reasons, you deduct the business-use percentage, not the full cost. Larger purchases can sometimes be deducted in full the year you buy them under Section 179 rather than spread out over several years, so talk to a tax preparer about which method saves you more.
Home Office, Internet, and Phone
If you have a space used regularly and exclusively for design work, you can take the home office deduction. You can use the simplified method (a flat rate per square foot, up to 300 square feet) or calculate actual expenses like a percentage of rent, utilities, and renters insurance based on the square footage of your office versus your whole home.
Your phone and internet bills are deductible based on business-use percentage. If you use your phone 60 percent of the time for client calls and project management, 60 percent of that bill is a write-off. Same logic applies to your internet if you work from home.
Client-Related and Business Costs
Domain registrations, web hosting, SSL certificates, and any staging environments you pay for on behalf of clients or your own portfolio site are deductible. So are business cards, a professional website, LinkedIn premium if you use it to find clients, and paid ads if you run them to promote your services.
Contractor payments matter here too. If you hire another designer or developer to help on a project, that payment is deductible, and if you pay them 600 dollars or more in a year, you likely need to send them a 1099-NEC.
Education, Memberships, and Professional Fees
Courses, certifications, conferences, and books that improve your design or development skills are deductible, as long as they relate to your current work rather than training for a totally different career. Membership dues for design associations or online communities count as well.
Any fees paid to a bookkeeper, tax preparer, or accounting software subscription are deductible business expenses. Bank fees on a business account and a portion of business-related travel, like flying to meet a client or attend a design conference, also qualify. Meals with clients are generally 50 percent deductible, not 100 percent.
Health Insurance and Retirement
If you buy your own health insurance because you do not have an employer plan, you may be able to deduct premiums as a self-employed health insurance deduction. This is not a Schedule C write-off but an adjustment on your personal return, and it directly lowers your taxable income.
Contributions to a SEP-IRA or Solo 401(k) are also deductible and reduce both your income tax and the amount subject to self-employment tax through Schedule SE. Keep every receipt, bank statement, and invoice organized throughout the year so these write-offs are easy to prove if the IRS ever asks.
