Working with a CPA for your tax filing will cost $200 to $500, depending on the complexity of your return -- how many schedules and extra forms need to be completed -- and where you live, according to the 2020-21 Fees Practices Survey released by the National Society of Accountants. Each additional schedule, for things like rental income or investment gains, can cost around $100.
If you have self-employment income, itemized deductions, investments or other complicated tax situations, the extra cost is likely to be worth it. It can also be easier to send off your forms to an expert and know they'll take care of everything. Remember that the extra amount you're paying in fees could get you a better return, making the upfront cost a smart investment.
Keep in mind, however, that it depends a lot on your individual filing situation, your withholdings and your tax bracket. As good as many software programs are, a human expert is often the way to go.
