Tax software has gotten genuinely good. For most W-2 employees with straightforward finances, filing your own taxes is fast, accurate, and free or close to it. You don't need a CPA to enter a W-2 and take the standard deduction.
But "most people" isn't everyone. There are specific situations where a CPA pays for itself, and a few where skipping one can be genuinely expensive.
You Probably Don't Need a CPA If…
You have W-2 income only. One or two jobs, standard deduction, maybe some student loan interest. Tax software handles this in thirty minutes.
You have simple investments. A brokerage account with some index funds. The 1099-B imports directly into most tax software and calculates your gains automatically.
You rent and don't itemize. The standard deduction ($15,000 for single filers in 2026) covers most people. If your itemizable expenses (mortgage interest, state taxes, charitable donations) don't exceed that number, there's nothing to optimize.
For these situations, use IRS Free File or a tool like FreeTaxUSA. Start with our Paycheck Calculator to estimate your liability, then file with confidence.
You Should Strongly Consider a CPA If…
1. You own rental property. Depreciation schedules, passive activity loss rules, repair vs improvement classifications, this is where DIY errors get expensive. A missed depreciation deduction on a $200,000 property costs you roughly $1,800 per year in unnecessary taxes.
2. You have business income over $50,000. Self-employment income triggers a web of deductions, estimated payments, and SE tax calculations. A CPA who specializes in small business can typically find enough deductions to more than cover their fee, and they'll set up your quarterly estimates correctly from the start.
3. You went through a major life event. Divorce (especially with property division or alimony), inheritance, death of a spouse, bankruptcy. These events create tax situations that don't map neatly to software interview questions. One wrong answer can cost thousands.
4. You received stock options or RSUs. ISO exercises, AMT calculations, disqualifying dispositions, equity compensation is one of the most error-prone areas in personal tax. A CPA who handles tech compensation regularly is worth every dollar.
The Middle Ground: Tax Software With Live CPA Access
TurboTax Live and H&R Block's online CPA review options give you software-guided filing with a human review before you submit. This works well for people whose situations are moderately complex, maybe a side business under $30,000 or a first-year rental property, but don't yet justify the full cost of a dedicated CPA.
Expect to pay $150–$250 for the live review tier, compared to $300–$600 for a basic CPA-prepared return and $800–$2,000+ for complex returns with business income, rentals, or equity compensation.
How to Find a Good CPA
Ask for referrals from people with similar financial situations. A CPA who's great for small businesses may not be the right fit for someone with stock options. Verify their credentials at the state board of accountancy. And ask upfront about fees. A good CPA will give you a clear estimate before they start.
The question isn't "do I need a CPA?" It's "would a CPA save me more than they cost?" For most W-2 employees, the answer is no. For anyone in the four situations above, it's almost certainly yes.
