How it works
Most freelancers overpay tax simply by forgetting deductions, and this checklist exists to stop that. Switch on each category that applies to you — home office, business mileage, software and subscriptions, the business share of your phone, health insurance premiums, retirement contributions, business meals and education — and enter the annual amount for each. The checklist totals the deductions and multiplies by your marginal tax rate to show the saving. A home office at $1,500, mileage at $2,000 and software at $600 is $4,100 of deductions, which at a 24% bracket is roughly $980 of tax you keep. Two mechanics are built into the arithmetic. Business meals count at only 50%, because that is all the tax code allows. And the phone line deducts only the business-use percentage you set, not the whole bill. The most valuable insight is what the marginal rate does: deductions reduce taxable income, not tax directly, so each $1,000 you find saves roughly your bracket — which is why a higher earner's checklist is worth more. Keep records for everything you claim, and note that self-employed health premiums are deductible only if you were not eligible for a spouse's employer plan.Formula
Total deductions x marginal rate = tax saved | meals at 50%, phone at business %
Tips
- Deductions cut taxable income, not tax directly — each $1,000 saves roughly your bracket.
- Meals count at 50% and the home office needs exclusive use — the two most over-claimed items.
- Deduct only the business share of your phone, not the whole bill.
- Self-employed health premiums apply only if a spouse's employer plan was not available to you.
- Keep records for everything — a deduction you cannot document is one you cannot keep.
