Tax software has made DIY filing accessible, but it is not always the best choice. Here is an honest breakdown of when professional preparation adds value.
When DIY Probably Works Fine
- You have one W-2 and no other income sources
- You take the standard deduction
- Your situation has not changed from last year
- You are comfortable navigating tax software
When a Preparer Adds Real Value
- Self-employment income: Schedule C deductions, self-employment tax, and estimated payments have complex rules that software may not navigate optimally
- Major life changes: Marriage, divorce, new baby, home purchase, retirement — each has tax implications that are easy to miss
- Rental property: Depreciation, passive activity rules, and state-specific rules add complexity
- Multi-state: If you lived or worked in multiple states, allocation rules vary
- IRS notices: If you have received correspondence from the IRS, professional help can prevent costly mistakes
- Business ownership: Entity structure, payroll, and deduction rules require expertise
The Hidden Cost of DIY Mistakes
The IRS reports that error rates on self-prepared returns are higher than professionally prepared returns for certain types of claims. Errors can lead to:
- Delayed refunds while the IRS processes corrections
- IRS notices that require time and stress to resolve
- Missed deductions that could have saved you money
- Penalties and interest on underpayments
What Professional Preparation Actually Costs
Professional preparation starts around $150 for simple returns. Compare this to the potential cost of a missed deduction, IRS notice response, or audit. For many taxpayers, the math works in favor of professional preparation.
