CPA or do-it-yourself — deciding as a gig driver
For most gig drivers, this is a cost decision more than a competence decision. A CPA add-on for a Schedule C averages $192 on top of a base return (National Society of Accountants), and a full self-employed return commonly runs $400–$900. Tax software built for self-employment — compared here — files the same forms for $0–$139. The gap in what you pay isn't a gap in what gets filed; it's a gap in judgment calls software can't make for you.
What actually changes the answer
Not your mileage total. Not how much you earned. What changes the answer is how many judgment calls your return actually requires:
Software handles well:
- A single 1099 income source (or several gig platforms, same shape of income)
- A mileage log already kept, standard mileage method, no mid-year vehicle change
- No home office, no depreciation, no prior-year amendments
A CPA earns their fee when:
- You have a W-2 job and gig income in the same year and need the two reconciled correctly — the mechanics of that specific overlap.
- You drove in multiple states with different gig-income tax treatment
- You're deciding standard mileage vs. actual expenses for the first time on a vehicle you also use personally, where the choice has consequences beyond this year's return
- You need to amend a prior return or resolve a wrong 1099 dispute with a platform that never got fixed on their end
- Your gig income is large enough that a CPA's fee is small relative to what a missed or wrong deduction would cost
The real comparison, side by side
| Cost | What it's good at | What it can't do | |
|---|---|---|---|
| Free software (FreeTaxUSA) | $0 federal + ~$15 state | Files Schedule C and SE correctly for a straightforward return | Won't flag a deduction you didn't know to look for, or advise on a multi-year strategy |
| Paid software (TurboTax, H&R Block) | $85–$139 | Same forms, more guided prompts and error-checking | Same limits — a prompt is not judgment |
| CPA | $192 add-on to $400–$900 full return | Judgment on ambiguous situations, planning ahead of next year, defending a return under audit | Costs real money for a return that didn't need the judgment |
What a CPA cannot change
No preparer — software or human — can turn a mile you didn't drive into a deduction, or apply a mileage rate other than the one that actually applied on the date you drove it. The 2026 split-year rate, and why the date matters. The value a CPA adds is entirely in judgment on genuinely ambiguous situations, not in finding deductions that were never real.

About MileTruth
MileTruth is an iOS app from Baker Ventures LLC that tracks deductible business mileage for gig and delivery drivers and shows true net pay: what is left after mileage, fuel and self-employment tax, not what the platform showed you at acceptance. It is built for people driving several platforms in the same shift, and for anyone who needs a mileage log that would hold up if the IRS asked for it. The app is in development.
Everything on this site is free and needs no account: the mileage deduction calculator, the per-platform pay breakdowns, and the answers, each one linked to the IRS publication or platform document it came from. MileTruth publishes the source for every number, including the 2026 split-year standard mileage rate, because a deduction you cannot substantiate is not a deduction.
Questions and answers
How much does a CPA cost for a gig driver's tax return?
The National Society of Accountants puts the average add-on cost for a Schedule C at 192 dollars on top of a basic return. A full self-employed return with Schedule C, home office and self-employment tax calculations more commonly runs 400 to 900 dollars, sometimes higher depending on region and how organized your records are.
Is it worth paying a CPA if I drive part-time?
Usually not, on cost alone. If your only income is one or two gig platforms with a mileage log already kept, tax software built for self-employment (FreeTaxUSA, TurboTax, H&R Block) handles the same Schedule C and Schedule SE forms for a fraction of a CPA's fee, and none of them require judgment calls a part-time single-income return typically needs.
When does a CPA start being worth the cost?
When your situation has more moving parts than software is built to reason about -- multiple income types (a W-2 job plus gig work plus other self-employment), multiple states, a home office deduction you're unsure how to calculate, vehicle depreciation from switching methods mid-ownership, or a prior-year mistake that needs amending. The complexity, not the mileage total, is what changes the calculus.
Can a CPA get me a bigger refund than software?
A CPA can catch deductions software won't prompt you for and can advise on decisions software can't make for you, like whether to elect actual expenses over standard mileage in a specific year. Neither can invent a deduction you don't actually qualify for, and IRS Publication 463's mileage rules apply the same way regardless of who prepares the return.
