Let's start with the honest part: for a genuinely simple year — one W-2, standard deduction, no life changes — TurboTax and its cousins are fine, and a preparer who tells you otherwise is selling, not advising. The question is where the line sits, because on the wrong side of it, "cheap" software becomes the most expensive way to file. Here are the five places that happens.
1. Cost — sticker price vs. real price
DIY software advertises free or cheap, but self-employment income, rental property, investment sales, and state returns each ratchet the price up — many filers land well north of $100 before hitting submit, with no human judgment included. A preparer costs more upfront — our fees are performance-based, quoted flat before any work begins — but that fee buys review, strategy, and accountability. The real comparison isn't fee vs. fee — it's fee vs. fee plus whatever the software missed.
2. Time — your evenings are worth something
The IRS itself estimates a non-business return takes hours to prepare — and self-employed filers multiply that. DIY means you're the bookkeeper, researcher, and reviewer. With a preparer, your job shrinks to uploading documents and answering questions; ours takes most clients under an hour of their own time, total.
3. Audit risk — and what happens when a letter arrives
Software checks arithmetic; it can't tell whether your home-office claim is defensible or your contractor should have been an employee. Judgment calls are where notices come from. And when a letter does arrive, software hands you an FAQ — a preparer picks up the phone, reviews the notice, and answers the IRS for you. That difference is worth more than any fee the year you need it.
4. Deduction discovery — software asks, an advisor notices
TurboTax can only surface what you know to answer "yes" to. It won't notice that your income makes an S-corp election worth modeling, that last year's return left education credits unclaimed, or that your side business qualifies you for a home-office and mileage combination you never thought to track. Our case reviews of self-filed returns regularly find four figures left on the table — which is why a review of your last three returns is free to ask about.
5. Year-round support — April vs. the other eleven months
Software exists for the six weeks before the deadline. But the moves that actually cut your tax bill — withholding tuning, estimated payments, entity choice, year-end timing — happen in June, September, and December. A preparer you can text in October is a different product from a login you remember in March.
The honest verdict
Simple W-2 year, comfortable with forms, nothing changed? Use the software — sincerely. Self-employment, equity comp, a home sale, multiple states, an IRS letter, or the nagging sense you're overpaying? That's when DIY quietly costs more than it saves.
