DIY vs Tax Pro: Which Wins?
The software costs $70, but the real cost of doing your own taxes is the 7 hours of your life — worth $280 at $40 an hour, for a DIY true cost of $350. A tax pro charges $400 and typically finds an extra $650 in missed deductions and credits on a complex return — so the pro wins by $600 net ($650 found minus the $50 it costs over DIY). But that story flips for a simple W-2 return. Below: the branch-by-branch math, the $600 worked example line by line, and the 60-second rule.
The $600 worked example, line by line
$70 software, 7 hours at $40/hr, $400 pro fee, $650 extra found, complex return:
DIY side: $70 software + 7 hrs × $40/hr = $70 + $280 = $350 true cost. That is the number everyone forgets — the software is the sticker price, your time is the real one. The IRS estimates a typical return takes 8+ hours including record-keeping, so 7 hours is conservative.
Pro side: the fee is $400 — only $50 more than DIY once your time is priced honestly. A good pro on a complex return (self-employment, rentals, K-1) typically finds $650 in missed deductions and credits: home-office details, depreciation mistakes, estimated-tax slips, misclassified 1099 income.
The verdict: $650 found − $50 extra cost = $600 net for the tax pro. The fee is almost an afterthought — the decision is really about the found money and your hours.
The three branches
| Branch | Typical math |
|---|---|
| Simple return (one W-2, standard deduction) | Pro finds $0–$100; DIY wins by roughly $250–$400. Software walks you through it in an hour. |
| Standard itemizer (homeowner, charitable gifts) | The toss-up branch — itemizing mistakes are common, and the pro earns the fee roughly half the time. |
| Complex return (self-employment, rentals, K-1) | The example branch: pro wins by $600 at the defaults. Pros pay for themselves here most years. |
The time-poor high-earner branch cuts across all three: if your hours are worth $100+ or the return eats a full weekend, DIY's true cost passes the pro's fee even before found money enters the picture. At $100/hr and 10 hours, DIY costs $1,070 against a $400 fee — the pro wins by $670 with zero found savings.
Output · formula · meaning
| Output | Formula | What it means |
|---|---|---|
| DIY true cost | software + (hours × hourly value) | $350.00 at the defaults — the real price, not the sticker. |
| Tax pro cost | the fee you enter | $400.00 at the defaults — $50 more than DIY. |
| Winner + net gap | extra found − (pro fee − DIY cost) | Tax pro wins by $600.00 at the defaults. |
| Branch analysis | complexity selection + time-vs-fee check | Which of the three branches your situation matches. |
Who uses this
- New freelancers and side-giggers: the first Schedule C year is the complexity cliff — run it before buying software.
- New homeowners: itemizing changes everything; the standard-vs-itemize fork is the pro's home turf.
- High earners short on time: the time branch decides for you — price the weekend honestly.
- Life-change years: marriage, a new business, rental income, inheritance — complexity spikes make one pro year worth it even for lifelong DIYers.
Accuracy & limitations
Uses generic, safe 2026 framing — not tax advice. The "extra found" input is the most uncertain number on the page: it is your estimate of what a good pro would catch, not a measured statistic. Pro fees vary widely by market and complexity (simple 1040s can run $150; complex business returns run well past $1,000). The calculator prices your time at the rate you enter — the opportunity cost of an evening is personal. Always confirm specifics with a licensed tax professional.

How much does a tax pro cost compared to DIY software?
DIY software runs $0 to about $150 for most returns (basic tiers are often free to file), while a CPA or enrolled agent typically charges $150–$600 for a standard return and more for business or rental complexity. The calculator's point is that the software price is not the DIY price — add your hours times your hourly value to get the true cost, and the gap shrinks fast.
When is doing your own taxes worth it?
When the return is simple: one W-2, the standard deduction, maybe a bank 1099. Software walks you through it in an hour or two, and a pro rarely finds more than $0–$100 of extra savings on returns like that. Set "Extra found" to $0 in the calculator and watch DIY win by the fee difference.
When does a tax pro pay for themselves?
When there is complexity to mine: self-employment, rental property, K-1s, major life changes (marriage, new business, home purchase, inheritance). Pros earn their fee on complex returns by catching missed credits, depreciation errors, and estimated-tax mistakes — the calculator's $650 default is the typical story for that branch.
What is the "true cost" of DIY taxes?
Software price plus your time: hours spent gathering documents, entering data, and reviewing, multiplied by what an hour of your time is worth. The IRS estimates a typical return takes 8+ hours including record-keeping. At the calculator's defaults (7 hours at $40/hr), the time is four times the $70 software cost.
Can a tax pro really find money I'd miss?
Sometimes — and the amount depends on complexity. On simple returns, rarely: software catches the same credits. On complex returns, commonly: pros report finding missed home-office deductions, depreciation mistakes, misclassified 1099 income, and overlooked credits. Be skeptical in the calculator (enter $0) and let the numbers convince you.
Should I hire a pro in a major life-change year?
Yes — this is the one branch even lifelong DIYers should respect. Marriage, divorce, a new business, rental income, a home purchase, or an inheritance each add forms and elections you have never filed before. One pro year buys you a correct baseline you can DIY from next year. The calculator's complexity selector has a branch for exactly this.
Does a tax pro save me time even if they don't save me money?
That is the time-poor high-earner branch: if your hours are worth $100+ or the return eats a full weekend, DIY's true cost passes the pro's fee before found money even enters the picture. At $100/hr and 10 hours, DIY costs $1,070 against a $400 fee — the pro wins by $670 with zero extra found.
What about free filing options?
They move the needle on the software side, not the time side: set "DIY software cost" to $0 and the calculator reprices everything. Free tiers cover basic returns well; the catch is the same as ever — the hours are still yours. For simple returns, $0 software plus one hour of your time usually beats the pro by the full fee.
