A US tax firm can usually require payment before it files a return or hands over the work it prepared, but it cannot hold the client's own records hostage. Circular 230 section 10.28 requires returning client records on request, even in a fee dispute. Because a completed copy must be given to the client when the return is presented for signature, collect payment before that step.
Key takeaways
- Circular 230 section 10.28 requires a practitioner to return a client's records promptly on request, and a fee dispute generally does not change that.
- Documents the practitioner prepared, such as the return itself, are outside that duty while the practitioner is withholding them pending payment of the fee for them.
- A signing preparer must give the client a completed copy of the return no later than when it is presented for signature, so payment should come before signing, not after.
- Contingent fees, such as a percentage of the refund, are generally prohibited for return preparation under Circular 230 section 10.27.
- The cleanest system is an engagement letter that states the order of steps, an invoice issued at review, and the signature request released only once it is paid.
Why do tax firms end up chasing fees after filing?
Most unpaid tax prep invoices come from the same sequence. The firm finishes the return, emails it for signature, the client signs Form 8879, the firm e-files, and the invoice goes out afterwards. At that point the client has everything they wanted. The firm's only lever is goodwill.
The fix is not to be tougher with clients. It is to move the payment step to the point where the client still wants something from the firm: before the return is presented for signature. That sounds simple, but the rules on what a preparer can and cannot hold back are often misunderstood, so it helps to start there.
This is general information about federal rules. State law and professional body rules, including state board of accountancy rules for CPAs, can add requirements, so check yours or speak to an ethics adviser before changing your policy.
What does Circular 230 say about returning client records?
Treasury Department Circular No. 230 governs attorneys, CPAs, enrolled agents and others who practice before the IRS. Section 10.28 says that when a client asks, the practitioner must promptly return any and all records of the client needed for the client to meet federal tax obligations. The practitioner may keep copies.
Two points catch firms out:
- A fee dispute generally does not change this. The section says so directly. Holding a client's W-2s, 1099s or brokerage statements until the bill is paid is not allowed under the federal rule.
- State law can narrow it, but not remove it. If state law lets a practitioner keep records in a fee dispute, the practitioner still has to return the records that must be attached to the return, and must give the client reasonable access to review and copy the rest.
What the section does not cover matters just as much. Records of the client do not include returns, claims for refund or other documents the practitioner prepared, where the practitioner is withholding them pending payment of the fees for those documents. In plain terms: the client's own paperwork goes back on request; the finished work product can wait for payment.
Can you hold back the return copy until the client pays?
Here is where the timing matters. Under Internal Revenue Code section 6107 and its regulation, a signing tax return preparer must give the taxpayer a completed copy of the return no later than the time it is presented for the taxpayer's signature. The copy can be electronic if both sides agree.
Failing to do so carries a penalty under section 6695(a). The inflation-adjusted figures published in Internal Revenue Bulletin 2025-45 list $65 per return for returns filed in 2027, with a maximum penalty of $33,000. The penalty does not apply where the failure was due to reasonable cause and not willful neglect.
So a firm cannot sensibly present a return for signature, collect the 8879 and then refuse to hand over the copy until the invoice is paid. Once the return goes out for signature, the copy goes with it. The leverage point is therefore before the signature request, not after it.
What can a firm hold back, and what must it hand over?
The table below summarizes the federal position for a typical individual client. It is a working guide built from Circular 230 section 10.28 and section 6107, not legal advice, and state rules may differ.
| Item | Before payment | Why |
|---|---|---|
| Client's original W-2s, 1099s, K-1s, statements | Return promptly on request | Client records under section 10.28; fee dispute generally no defense |
| Records the client gave the firm, scanned or uploaded | Return or give access on request | Same rule; the firm may keep copies |
| Draft return and workpapers prepared by the firm | May withhold pending payment of the fee for them | Excluded from client records while withheld for that fee |
| Return presented for signature (Form 8879 request) | A completed copy must go with it | Section 6107 copy rule |
| E-filing the return | A business decision once signed; set out in the engagement letter | Agree terms in advance; consider the client's deadline |
| Prior-year return the firm prepared and the client still needs | Check carefully before withholding | Some prior-year documents can count as client records |
The last row deserves care. Section 10.28 can treat documents a practitioner prepared in an earlier, completed engagement as client records if the client needs them for current federal tax obligations. If a client who paid last year asks for last year's return, send it.
How should the engagement letter set up payment?
The engagement letter is where the order of steps is agreed, before any work starts. It should say, in plain words:
- The fee or how it is calculated, and that it is a fixed or time-based fee, not a percentage of any refund. Circular 230 section 10.27 generally prohibits contingent fees for return preparation, with narrow exceptions such as certain examination work.
- That the invoice is issued when the return is ready for review, and the return is sent for signature once the invoice is paid.
- That the client's own documents will be returned on request at any time.
- What happens if payment is not received before the filing deadline, for example that the firm will discuss filing an extension with the client.
Clients rarely object to terms they have agreed in advance. They object to surprises. If the letter is e-signed through the portal at the start of the season, the firm has a dated record of what was agreed.
A worked example: what payment-first is worth
Consider an illustrative three-preparer firm filing 600 individual returns a season at an average fee of $450, so about $270,000 in billings. These figures are invented to show the effect.
Under the old file-then-invoice sequence, the firm finds that 8% of invoices are still unpaid 60 days after filing, about 48 clients and $21,600. Staff spend roughly 25 minutes per unpaid client on reminders and calls, around 20 hours in total, and in the end the firm writes off a quarter of that balance, $5,400.
After moving the invoice to the review stage and releasing the signature request only on payment, the firm finds most clients pay within a day, because they want their refund filed. A small number delay, and those are visible in a single list before the deadline, not discovered in June. Even if write-offs fall only by half, the firm keeps about $2,700 a season plus most of those 20 hours, in the weeks when hours are scarcest.
The figure that matters most is not the write-off. It is that the firm stops doing collection work during filing season. Collection calls in April compete with review time, and review time is where errors are caught. Moving payment earlier protects quality as well as cash.
Track two numbers to see whether the change is working: the share of invoices paid before the signature request goes out, and the number of days between invoice and payment. If either slips, look first at how the invoice is presented, not at the client.
What should a payment-first workflow look like step by step?
- Engagement letter e-signed before work starts, with the payment sequence written in.
- Documents collected through a secure upload, not email attachments.
- Return prepared and reviewed internally.
- Invoice issued the moment review is complete, with an online payment link.
- Payment received: the signature request and completed return copy are released together, meeting the section 6107 copy rule.
- Client signs Form 8879, and the firm e-files.
- Acceptance confirmed and the final package delivered.
If a client has not paid within a few days of the invoice, send one reminder with the link and one personal message. If clients still struggle to find documents, our guide to what to look for in a client portal helps, and the signature step itself is covered in our Form 8879 e-signature guide.
Keep one exception route. A client facing a deadline who disputes the fee should not be left with no return and no extension. Decide in advance who in the firm can approve filing first, and record why.
How Zaquil handles collecting fees before releasing the return
Payment-first only works if it happens without staff policing every file. Zaquil puts the sequence into the workflow itself.
Engagement letters e-signed in the portal. The client receives the engagement letter in a branded secure client portal, reads the payment terms and e-signs. The firm keeps the signed PDF certificate on the client record.
Invoice at review, paid online. When the return job reaches the review stage, the firm raises the invoice, including any unbilled time. The client sees it in the portal and pays online.
Documents locked until the invoice is paid. The firm uploads the completed return and the signature request to the portal and locks them to that invoice. The client sees that the return is ready and what is due. Once the invoice is paid, the return copy and the e-signature request open together, so the copy and the signing step stay in step. The client's own uploaded records are never locked and remain available to them.
Automations for the gap. A rule sends a payment reminder two days after the invoice, creates a call task after five, and moves the job to e-file once payment and signature are both in.
One inbox. Questions about the bill, whether by email, SMS or WhatsApp, arrive in one place against the client record.

Frequently asked questions
Can a tax preparer refuse to file a return until they are paid?
Federal rules do not require a preparer to e-file before payment, and many firms set out in the engagement letter that filing follows payment. The firm must still return the client's own records on request, and once the return is presented for signature a completed copy must go to the client. State law and professional body rules may add requirements, so check them before adopting a policy.
Can I keep a client's W-2s and 1099s until they pay my bill?
Generally no. Circular 230 section 10.28 requires a practitioner to promptly return a client's records needed for federal tax compliance when the client asks, and a fee dispute generally does not relieve that duty. Where state law allows retention in a fee dispute, the practitioner must still return records that must be attached to the return and give reasonable access to the rest.
Is the tax return I prepared a client record?
Not while you are withholding it pending payment of the fee for it. Circular 230 section 10.28 excludes returns, claims for refund and other documents the practitioner prepared from client records in that situation. However, documents prepared in an earlier, completed engagement may count as client records if the client needs them for current federal tax obligations, so be careful with prior-year returns.
When must a preparer give the client a copy of the return?
Under Internal Revenue Code section 6107, a signing tax return preparer must give the taxpayer a completed copy of the return no later than the time it is presented for the taxpayer's signature. The copy may be electronic if both parties agree. This is why collecting payment before sending the signature request works better than invoicing after filing.
What is the penalty for not giving a client a copy of the return?
The penalty under section 6695(a) applies per failure. Inflation-adjusted figures in Internal Revenue Bulletin 2025-45 list $65 per return for returns filed in 2027, with a maximum penalty of $33,000. The penalty does not apply if the failure was due to reasonable cause and not willful neglect. Check the current bulletin for the year in question, because the amounts are adjusted annually.
Can I charge a percentage of the client's refund?
Generally no. Circular 230 section 10.27 prohibits contingent fees for services in connection with matters before the IRS, and a fee based on a percentage of the refund is a contingent fee. There are narrow exceptions, such as certain work related to an IRS examination or a claim filed solely for interest and penalties. Ordinary return preparation should be priced as a fixed or time-based fee.
Should I take payment before starting the return?
Some firms take a deposit or full payment upfront, especially for new or complex clients, and that is a valid choice. Others invoice at review, which ties payment to finished work and still keeps it ahead of the signature step. The key is to state the approach in the engagement letter so the client agrees to it before any work begins.
What if the client disputes the fee close to the deadline?
Do not leave the client with neither a return nor an extension. Talk to the client, document the dispute, and decide whether to file an extension or file the return while the fee discussion continues. Agree in advance who in the firm can approve an exception. Remember that the client's own records must still be returned on request.
Does this apply to CPAs as well as enrolled agents?
Circular 230 applies to attorneys, CPAs, enrolled agents, enrolled actuaries and others who practice before the IRS. CPAs are also subject to their state board of accountancy rules and, for members, professional ethics codes, which can contain their own record-retention rules. A CPA firm should check both sets of rules before setting a fee-collection policy.
How do I word the payment terms in an engagement letter?
State the fee or how it is calculated, that it is not contingent on the refund, when the invoice will be issued, and that the return will be sent for signature once the invoice is paid. Add that the client's own documents will be returned on request at any time, and what happens if payment is not made before the filing deadline.
Can I lock the return in a client portal until the invoice is paid?
Locking the firm's prepared return and signature request until payment is consistent with withholding work product pending payment of the fee for it. Do not lock the client's own uploaded records, which must stay available on request. When payment releases the return, send the completed copy and the signature request together so the copy reaches the client when the return is presented for signing.
Will payment-first put clients off?
Clients rarely object to terms agreed at the start, especially when payment is a single online link. Most clients who want their refund filed pay within a day of the invoice. Friction usually comes from surprises, such as an unexpected bill after filing, so explaining the sequence in the engagement letter is what makes it work.
