Every dollar of legitimate business expense reduces the profit you pay tax on. Deductions are one of the few levers that actually move a freelancer's bill, but the expense has to be real, ordinary, and necessary for your work. Here's a grounded look at what counts.

Deductions people commonly miss

  • Home office. Use part of your home regularly and exclusively for business and you can deduct a portion of rent, utilities, and insurance. Don't want to track actual costs? The simplified method gives you a flat rate per square foot.
  • Health insurance premiums. Self-employed people can often deduct premiums for themselves and their family as an adjustment to income.
  • Half of self-employment tax. As covered in our SE tax guide, one half is deductible.
  • Software and subscriptions. Design tools, accounting apps, hosting, and the other tools you use to deliver work.
  • Education tied to your current field. Courses that maintain or improve skills you already use professionally.
  • A portion of your phone and internet. The business-use percentage, not the whole bill.
  • Retirement contributions. A Solo 401(k) or SEP IRA can shelter a large amount of income. It's one of the most powerful deductions available to the self-employed.

Deductions people get wrong

Some of the "tips" floating around online will create problems in an audit:

  • Your entire rent. Only the exclusive-use business portion qualifies, not the whole apartment.
  • Regular clothing. A wardrobe you could wear in everyday life isn't deductible, even if you bought it for client meetings. Genuine uniforms or protective gear are a different story.
  • Commuting. Driving from home to a regular workplace is personal, not business mileage.
  • Lavish meals "because you discussed business." Business meals have specific rules and are usually only partly deductible. Treat every dinner as a write-off and you're asking for scrutiny.

The habit that makes deductions easy

The single best thing you can do is keep business and personal money separate. A dedicated business checking account and one card used only for business turns tax time from archaeology into a download. Pair it with a simple rule. If you can't explain why an expense is necessary for your work, don't claim it.

Documentation beats memory

The IRS doesn't care that an expense felt business-related. It cares whether you can show it was. Keep receipts (a photo is fine), note the business purpose, and let your accounting tool categorize as you go. Deductions you can't support aren't savings. They're risk.

Educational information only, not tax advice. Deduction rules are detailed and change — confirm your situation with a qualified professional.
