How this estimate works
This tool doesn't quote statistics about "people like you" — it estimates from your own numbers. Picking a line of work just surfaces the deduction categories people in that work most commonly under-track (the same categories RevvFi tracks in the app). You enter what you actually spend; we total the deductions, then estimate the tax impact by computing a simplified federal tax bill with and without them — so the headline figure includes both self-employment tax and income tax, at your income, not a flat guess.
- Partial-use stays partial. Phone & internet asks for your business-use percentage instead of assuming 100%.
- Meals are capped. Qualifying business meals are generally only 50% deductible — the limit is applied for you.
- Home office is capped. Simplified method: $5 per square foot up to 300 sq ft — $1,500 max.
- Mileage never overstates. 2026 is a split year ($0.725/mi Jan–Jun, $0.76/mi Jul–Dec); all 2026 miles are valued at the lower rate.
Why people miss these
Almost nobody forgets a $2,000 laptop. What slips is the $14 subscription, the nine-mile drive, the business half of a phone bill — small amounts that repeat all year. By April there's no record, and no record means no deduction. RevvFi keeps the record for you: bank sync, receipt scanning, and mileage tracking in one app.
Common questions
What deductions do self-employed people miss most?
Vehicle mileage, the home office, the business-use share of phone and internet, software subscriptions, and platform fees. They slip through because they need year-round records — small repeating amounts rather than one big receipt.
Can I deduct my phone and internet?
Only the business-use portion. If you use them roughly half for work, you can generally deduct about half the cost. That's why this estimator asks for a percentage instead of assuming 100%.
How does the simplified home-office deduction work?
You deduct $5 per square foot of space used regularly and exclusively for business, capped at 300 square feet — a $1,500 maximum (IRS Rev. Proc. 2013-13). An actual-expense method also exists and can be larger, but requires detailed records.
Are business meals 100% deductible?
Generally no — qualifying business meals are generally limited to 50%. The estimator applies that limit automatically to whatever you enter.
