Self-Employed Tax Deduction Checklist

Q: What can I deduct as a self-employed freelancer?

Ordinary and necessary business costs are deductible on Schedule C: home office, equipment, supplies and software, business mileage, 50% of business meals, travel away from home, business insurance, and professional or legal fees. Self-employed health insurance is deductible too, but as a Schedule 1 adjustment, not on Schedule C. This checklist tracks each one and estimates the value.

Q: How much is a tax deduction actually worth?

A deduction's value equals the deduction amount times your marginal income tax rate, plus self-employment tax savings of about 14.13% (15.3% on 92.35% of net profit) for Schedule C deductions. Example: a $1,000 Schedule C deduction in the 22% bracket saves roughly $220 in income tax plus $141 in SE tax, about $361. Health insurance saves income tax only.

Q: How does the home office deduction work?

The simplified method is $5 per square foot of space used regularly and exclusively for business, capped at 300 square feet, so the maximum is $1,500. The space must be dedicated to business and the deduction cannot exceed the income from that business use.

Q: What is the standard mileage rate?

The IRS business standard mileage rate is 70 cents per mile for 2025 and 72.5 cents per mile for 2026. Commuting from home to a regular workplace is not deductible — only business miles count.

Q: Why are business meals only 50% deductible?

Ordinary business meals are limited to 50% deductibility for 2025 and 2026, so the tool automatically applies the 50% haircut. Entertainment (tickets, golf) is generally not deductible at all since the TCJA.

Q: Is this tax advice?

No. This is a free educational estimate, not tax advice and not a substitute for a CPA or a filed return. It ignores phase-outs, AMT, state tax, QBI, and credits. Confirm everything with a tax professional before filing.

Self-Employed Tax Deduction Checklist — guide & how to use

What it does

Freelancers and single-member LLCs routinely overpay tax because they don't know what's deductible. This interactive checklist walks you through the nine biggest Schedule C deduction areas — home office, equipment, supplies, mileage, meals, travel, business insurance, professional fees, and self-employed health insurance — applies the correct IRS rules (the 50% meals haircut, the $5/sq ft home-office cap, the current mileage rate), and shows your estimated total deductions plus the tax you'd likely save. Everything runs privately in your browser. It is an estimate, not tax advice.

How a deduction turns into savings

A deduction doesn't come back to you dollar-for-dollar — it lowers the income you're taxed on. Its value is the deduction amount times your marginal income tax rate, and (for Schedule C costs) it also trims the 15.3% self-employment tax on 92.35% of your profit — about 14.13% more. So a Schedule C deduction in the 22% bracket is worth roughly 36 cents on the dollar.

Worked example

A freelance designer in the 22% bracket, 2025, with SE tax savings on, enters:

Home office: 120 sq ft → 120 × $5 = $600
Equipment (laptop + monitor): $2,000 → 100% = $2,000
Supplies & software: $900 → 100% = $900
Business miles: 1,200 → 1,200 × $0.70 = $840
Business meals: $600 → × 50% = $300
Professional fees (accountant): $500 → 100% = $500

Schedule C subtotal = $600 + $2,000 + $900 + $840 + $300 + $500 = $5,140. Income-tax savings = $5,140 × 22% = $1,131. SE-tax savings = $5,140 × 14.13% = $726. Estimated tax savings ≈ $1,857 ($1,131 from income tax + $726 from SE tax) on $5,140 of deductions. Add $4,000 of health insurance and total deductions become $9,140, with only the 22% income-tax savings ($880) added — health insurance never reduces SE tax.

How to use it

Pick your tax year and marginal bracket (the default is 22%, the most common for mid-income freelancers).
Leave the SE tax toggle on unless you had a net loss for the year.
Enter what you actually spent in each category — leave the rest at zero.
Read your total deductions, estimated savings, and the per-category breakdown, then use Copy result or Print to PDF to hand it to your accountant.

The rules this tool applies

Home office (simplified): sq ft × $5, capped at 300 sq ft / $1,500. Must be regular & exclusive use.
Mileage: miles × $0.70 (2025) or × $0.725 (2026). Commuting miles don't count.
Meals: 50% deductible. Entertainment is generally 0%.
Equipment, supplies, travel, business insurance, professional fees: 100% (equipment via Section 179 / de minimis safe harbor for typical amounts).
Health insurance: a Schedule 1 adjustment — reduces income tax and AGI but not SE tax, limited to net SE profit.

Common mistakes this checklist helps you avoid

Deducting 100% of meals instead of 50%.
Counting commuting miles as business miles.
Claiming a home office that isn't used regularly and exclusively for business.
Double-dipping standard mileage and actual car expenses for the same vehicle.
Putting health insurance on Schedule C and expecting it to cut SE tax (it doesn't).
Deducting 100% of mixed-use phone, internet, or car instead of the business-use share.
Treating client entertainment (tickets, golf) as deductible.
Assuming the "savings" figure is a refund — it's an estimate of reduced tax, not money back.

Accuracy & limits (read this)

This is an estimate and educational checklist, not tax advice and not a substitute for a CPA or filed return.
"Tax savings" assumes the deduction stays within one bracket; it ignores phase-outs, AMT, state tax, QBI (Sec. 199A), and credits.
SE-tax savings use the simple 14.13% figure (15.3% × 92.35%). A more precise figure nets out the deduction for one-half of SE tax.
Home office simplified method = $5/sq ft, 300 sq ft / $1,500 max for both 2025 and 2026; the deduction can't exceed gross income from that use.
Large or mixed-use equipment may need Section 179 / depreciation rather than a 100% same-year write-off — confirm with a preparer.
