DIY software vs hiring a tax professional
For most people with straightforward situations, quality DIY software handles a federal and state return accurately and costs significantly less than professional preparation. For people whose financial lives have grown more complex — self-employment, rental income, major life changes, multi-state filing — the cost of a credentialed tax professional is usually justified by the reduction in errors, missed credits, and potential compliance risk. The question is not which option is better in the abstract; it is which one fits your current situation.
When DIY software is likely sufficient
Software products from reputable publishers walk users through interview-style questions that cover the most common situations. You are a reasonable candidate for DIY if your situation looks like this:
- You receive a W-2 from a single employer and have no other income sources
- Your only investment income is interest or dividends reported on a 1099-INT or 1099-DIV, with no stock sales or cryptocurrency transactions
- You claim the standard deduction rather than itemizing
- You have no dependents with complicated situations (such as custody splits or children with their own unearned income)
- You did not move to a new state during the year
- You had no significant life events: no marriage, divorce, death of a spouse, adoption, or inheritance during the tax year
- You are not self-employed or a sole proprietor
If all of the above apply, the main value a professional adds is peace of mind and time savings — both real, but not strictly necessary.
Signals your situation warrants a professional
Complexity accumulates. Any one of the following factors can introduce enough nuance that a mistake in software becomes costly:
Self-employment or gig income If you received income on a 1099-NEC, 1099-K, or as a sole proprietor, you are responsible for self-employment tax as well as income tax. Business expense deductions, home-office treatment, and estimated payment calculations involve judgment calls that software handles inconsistently depending on how you answer the interview questions.
Rental property Rental income requires a Schedule E. Depreciation calculations, passive activity loss rules, and the treatment of repairs versus capital improvements are areas where errors are common and can surface years later on audit.
Stock sales, restricted stock units, or cryptocurrency Cost-basis reporting errors are among the most frequent causes of IRS notices. If you sold shares acquired through an employee stock plan, the broker may have reported only the proceeds — not the adjusted basis — on the 1099-B, which means software pre-fills an inflated gain if you do not manually correct it.
Multi-state filing obligations If you lived in more than one state during the year, worked remotely for an out-of-state employer, or have investment income sourced to another state, you may owe returns in multiple states. The allocation rules differ by state and interact with each other in ways that software often handles incorrectly.
Major life events Marriage, divorce, a spouse's death, the birth or adoption of a child, receiving an inheritance, or taking a distribution from a retirement account each introduce specific forms, elections, and calculations. A missed election (for example, not making a timely portability election after a spouse's death) can have lasting financial consequences.
Foreign income or accounts US persons with foreign income or foreign financial accounts face additional disclosure requirements — including FBAR filings and potentially Form 8938 — that carry significant penalties for non-filing. This is an area where professional guidance is particularly valuable.
Prior-year issues If you received a notice from the IRS related to a prior year, or if you need to file amended returns, a credentialed professional — particularly an enrolled agent — is well-positioned to handle the correspondence.
The middle ground: assisted filing
Some software providers offer an add-on where a credentialed professional reviews your return before it is filed. This costs more than pure DIY but less than full-service preparation, and it provides a second set of eyes on the output. It is worth considering if your situation is mostly straightforward but includes one or two areas of uncertainty.
How to decide
A practical approach: start the software interview for free before committing to purchase. If you hit questions you cannot confidently answer — about depreciation, passive losses, basis adjustments, or foreign assets — that is a signal the situation has outgrown DIY.
If you decide to use a professional, verify their credentials before sharing your documents. The IRS PTIN directory (irs.gov/tax-professionals) lets you confirm a preparer is registered. Enrolled agents and CPAs have additional verifiable credentials through the IRS and state boards of accountancy respectively.
Find a verified professional
If your situation includes any of the complexity signals above, browse the directory on TaxProsRated to find credentialed professionals by location and specialty. Filter by credential type to find enrolled agents, CPAs, or other licensed preparers.
