Key Takeaways

  • Front-load your software purchases and CE courses in Q4 of the prior year so you can deduct them in the earlier tax year and have everything ready for the upcoming filing season.
  • If you offer refund transfer (bank product) services, track the fees per return. The bank product fees you pay to your software vendor are deductible, even though the client ultimately bears the cost through the refund.
  • Consider IRS Circular 230 continuing education as a deductible expense even if you are not an EA. Courses that keep you current on tax law changes are deductible for any paid preparer.

As a self-employed tax preparer, you know the rules inside and out for your clients, but are you applying the same rigor to your own return? From tax software licenses to PTIN renewal fees, your practice expenses are all deductible. This checklist ensures you capture every write-off relevant to tax preparation professionals for 2026.

Use this interactive checklist to review every deduction you might be eligible for. Check off items as you go to track your progress. Each deduction includes the Schedule C line where it belongs, plus a concrete example specific to your profession.

Common Mistakes to Avoid

Forgetting to deduct your own PTIN renewal fee because the amount is small.

The PTIN renewal is a required professional fee and fully deductible. It may be small, but combined with other licensing fees it adds up.

Not deducting e-file transmission fees and bank product costs passed through by your software vendor.

Review your tax software vendor statements for all per-return fees charged during the filing season. Each is a deductible business cost.

Missing the deduction for tax research databases because they are bundled with other services.

If your research subscription (Checkpoint, CCH) is bundled with software, break out the cost if possible. If not, deduct the full bundle as a software expense.

Overlooking secure document destruction (shredding) as a deductible expense.

Shredding client documents after the retention period is a business necessity. Deduct the cost of shredding services, bins, or in-office shredders.

Not tracking seasonal office expenses separately from year-round costs, leading to confusion about deductible amounts.

If you lease seasonal office space, track those costs separately. All rent, utilities, and setup costs during the lease period are fully deductible.
