How do I split a tax preparation fee?

Updated October 10, 2026 路 Schedule C, Line 17
Short answer Schedule C, Line 17 Legal and professional services

A tax prep fee covering the 1040 and Schedule C belongs on Line 17, legal and professional services.

Why line 17

The business share goes on line 17 and the personal share is not deductible anywhere, so the allocation is the whole value of the exercise. Ask the preparer to itemise the invoice by form or by time: Schedule C, Schedule SE, Form 4562, Form 8829, the bookkeeping clean-up and the 1099 filings are business, while Form 1040 itself, Schedule A, Schedule B, Schedule D and your state personal return are not. Most preparers will do this on request, and a preparer's own breakdown is far stronger support than a percentage you estimated afterwards. Where they will only give one figure, a time-based split described in writing is the fallback.

Stop looking up lines one at a time. ClaryBook totals your year into an IRS Schedule C worksheet in form order, Part I and Part II line by line, so a tax prep fee covering the 1040 and Schedule C lands on Line 17 without you sorting it.

What a tax prep fee covering the 1040 and Schedule C is confused with

not deductible, not deductible
The personal return portion is not deductible at all, since the miscellaneous itemised deduction that used to carry it is not currently allowed.
Line 27a, other expenses
Software you use to file your own return is not professional services, so a self-filing subscription is better described in Part V to line 27a at its business share.
Line 23, taxes and licenses
A state filing fee or franchise charge the preparer pays on your behalf is a tax or licence on line 23, not part of the professional fee.

What to keep

Ask for an invoice itemised by form or by time and keep it with the return. If the breakdown is an estimate, get it in writing from the preparer rather than making it yourself, and keep the engagement letter describing the scope.
