CPA or tax software — which one actually saves you money?

It comes down to four numbers: software cost, CPA cost, the value of the hours you save, and the deductions a pro is likely to surface that you would miss. This calculator runs all four and shows your break-even — the deduction savings at which the CPA pays for itself. For simple returns software often wins; as complexity rises, a CPA usually does.

Est. $200-$600 for a straightforward individual return and $500-$2,500+ for a small business or complex return, depending on entity type and bookkeeping state. Tax software runs roughly $0-$200 for individuals and $100-$400 for business editions. The calculator lets you enter your real quotes instead of guessing.

Break-even is the dollar amount of additional deductions or saved time at which the CPA cost equals the software cost. If a CPA costs $800 more than software, the CPA pays off the moment they find $800 of tax savings or time value you would have lost. The calculator shows this line so the decision stops being a gut call.

It depends entirely on complexity — a W-2 employee with a standard deduction has little room, while a business owner with home office, vehicle, retirement, and entity-structuring decisions has a lot. Est. savings scale with complexity, which is exactly why this calculator weights the deduction estimate by the complexity level you choose.

For a clean sole proprietorship with simple income, often yes. Once you have an S-corp election decision, multi-state issues, depreciation, or payroll, the cost of getting it wrong usually exceeds the CPA fee. The calculator helps you see the threshold rather than defaulting to whatever you did last year.

Take the hours you spend and multiply by what an hour of your time is worth — your effective hourly earnings, not minimum wage. A business owner spending 15 hours wrestling with software is spending real money even before errors. The calculator folds your time value into the comparison so the DIY option carries its true cost.

Complexity is how many moving parts your return has: side income, a business, property, investments, multi-state, dependents, retirement accounts. More parts mean more places to legally save and more places to make a costly mistake. The calculator uses complexity to estimate how much a pro is likely to find that software would miss.

Often, but not always — that is the whole point of running the numbers. For a simple return the answer is frequently no. For a complex business return the deduction and time savings usually clear the fee comfortably. Use the break-even line in the calculator to decide for your situation instead of following a rule of thumb.
