Client Document Request Email Templates for CPAs

1. Initial request at engagement start

Send: when the engagement begins, or mid-January

Set expectations once: what you need, how to send it, and the date that keeps them on schedule.

Subject: Your [TAX YEAR] tax return: documents we need by [DUE DATE] Hi [CLIENT FIRST NAME], Thanks for working with us again this year. To get your [TAX YEAR] return started, please send the documents below by [DUE DATE]. Getting everything to us by then leaves time to prepare and review your return well before the [FILING DEADLINE] deadline. What we need from you: [LIST OF DOCUMENTS, e.g. W-2s, 1099s, Form 1098, charitable receipts] You can upload everything securely here: [UPLOAD LINK] Please don't send tax documents as regular email attachments. Not sure what applies to you? This checklist covers the most common items: https://domodomu.com/resources/tax-document-checklist If anything changed this year (a new job, a move, a new child, a property bought or sold), just let us know when you upload. Thank you, [YOUR NAME] [FIRM NAME] · [PHONE]

2. Friendly reminder

Send: about 1–2 weeks before the due date

Short and specific. Tell them what you already have so the request feels manageable.

Subject: Quick reminder: [TAX YEAR] documents due [DUE DATE] Hi [CLIENT FIRST NAME], Just a friendly reminder that we're collecting documents for your [TAX YEAR] return by [DUE DATE]. So far we've received: [RECEIVED ITEMS] Still needed: [OUTSTANDING ITEMS] You can upload them here: [UPLOAD LINK] Some forms, like brokerage statements and K-1s, arrive later in the season. If you're still waiting on one, send what you have now and the rest when it comes. Thanks, [YOUR NAME] [FIRM NAME]

3. Final reminder before the deadline

Send: 2–3 business days before the due date

Be clear about what happens next, including an extension if that's your firm's policy — without sounding like a threat.

Subject: Action needed: [TAX YEAR] documents due [DUE DATE] Hi [CLIENT FIRST NAME], We still need a few documents to finish your [TAX YEAR] return, and our cutoff to file by [FILING DEADLINE] is [DUE DATE]. Still needed: [OUTSTANDING ITEMS] Upload here: [UPLOAD LINK] If we don't have everything by [DUE DATE], we'll [FIRM POLICY, e.g. file an extension on your behalf]. An extension gives more time to file, but not more time to pay any tax you owe, so we'd much rather get it done on time. If something is holding you up, reply to this email or call us at [PHONE] and we'll help. Thank you, [YOUR NAME] [FIRM NAME]

4. Missing-item follow-up

Send: as soon as you spot a gap during preparation

Explain why you need the item. Clients act faster when they understand what it's for and where to find it.

Subject: One more item for your [TAX YEAR] return Hi [CLIENT FIRST NAME], Thanks for the documents you sent. While preparing your return, we noticed we're missing: [MISSING ITEM] Why we need it: [REASON, e.g. "Your bank statements show interest from [BANK NAME], so we need the Form 1099-INT they issued."] Where to find it: [HINT, e.g. "Usually in the Tax Documents section of your online banking."] Upload it here: [UPLOAD LINK] If you don't have it or think it doesn't apply, just reply and let us know, and we'll take it from there. Thanks, [YOUR NAME] [FIRM NAME]

5. Thank you, everything received

Send: the day the last document arrives

Close the loop so they stop wondering, and tell them what happens next.

Subject: Got everything, thank you! Hi [CLIENT FIRST NAME], Thank you, we've received everything we need for your [TAX YEAR] return. Next steps: - We'll prepare your return and expect to have it ready for your review by [REVIEW DATE]. - We'll send it to you for review and signature before filing. - If we have any questions in the meantime, we'll reach out. If you receive any new or corrected tax forms (a corrected 1099 or a late K-1, for example), please upload them here right away: [UPLOAD LINK] Thanks again, [YOUR NAME] [FIRM NAME]

Tips on timing

Start in January. Employers and most payers must send W-2s and many 1099s by January 31, so mid-January requests land just as forms start arriving.
Set your own due date, not the IRS's. A firm cutoff several weeks ahead of the filing deadline (for example, mid-March for April returns) gives you room to prepare and review.
Plan for late forms. Brokerage statements and Schedule K-1s often arrive in February or March, and later for some partnerships. Ask for everything else first.
Space reminders out. One reminder 1–2 weeks before your cutoff and a final one a few days before is usually enough. More than that starts to read as noise.
Always say what's missing. “We still need your 1098” gets a faster response than “please send your remaining documents.”
Use a secure upload method. Tax documents contain Social Security numbers and account numbers; avoid regular email attachments.

These templates are general examples for firms to adapt. Deadlines vary by return type, state and fiscal year, and nothing here is tax or legal advice. Review your firm's engagement terms before promising any filing or extension action.
