Tax organizer cover letter: what to send clients with this year’s organizer

The organizer asks the questions. The letter gets it opened and returned on time. Here a cover letter is the firm’s note to the client that travels with the organizer, not a job application, and it should fit on one page.

Each paragraph answers one thing the client would otherwise phone about. The table lists them in the order they appear in the template.

Copy the paragraphs below in order and fill in the [bracketed] fields. Delete any paragraph that does not apply to the client, such as the engagement letter line when it is not being renewed.

1. Dear [Client name], your organizer for the 2026 tax year is enclosed. Thank you for trusting [Firm name] with your return again.
2. In this packet: the organizer, a one-page update sheet, the list of documents we expect from you based on last year, and [our engagement letter for this year].
3. Please return everything by [return date]. Anything that arrives after [cut-off date] may be filed on extension, which gives more time to file but not to pay.
4. Upload your answers and documents through [secure upload link]. Please do not email Social Security numbers or bank details: email is not a safe way to send them.
5. If nothing changed since last year, fill in the update sheet and upload your forms. You do not need to complete every page of the organizer.
6. The 2025 tax law added deductions that also apply this year, and a new charity deduction starts in 2026. Please answer the questions on tips, overtime, a new car loan, age and charitable gifts, even if you think they do not apply.
7. If you have an Identity Protection PIN, send us this year’s PIN. A new one is issued every year.
8. Our fees are set out in [the engagement letter or fee schedule]. Questions go to [staff name] at [phone] or [email], [office hours].
9. Sincerely, [Your name], [Title], [Firm name], [Address].

Send the packet once clients start receiving their year-end forms, usually in January, so they can answer and upload in one sitting. A letter that arrives before the forms gets put aside.

Choose a return date ahead of your own internal cut-off, not the filing deadline itself. That leaves room to review, ask follow-up questions and chase missing documents. Say plainly what happens after the date, for example that the return moves to the extension list.

The 2025 tax law added deductions that run from 2025 through 2028, for tips, overtime, car loan interest on a personal-use vehicle and taxpayers 65 or older (IRS fact sheet, Tax deductions for working Americans and seniors). Clients will not mention them unless asked, so the letter points to those questions.

From tax year 2026, people who do not itemize may deduct up to $1,000 of cash gifts to eligible charities, or $2,000 on a joint return (IRS, Working Families Tax Cuts provisions). That makes donation receipts worth sending even for clients who take the standard deduction.

Fewer forms will arrive for some clients. For payments made after 2025, the Form 1099-NEC and Form 1099-MISC threshold rose to $2,000 (Instructions for Forms 1099-MISC and 1099-NEC). The letter should remind clients that income still counts when no form comes.

Finally, an Identity Protection PIN is a six-digit number that blocks anyone else from filing with the client’s Social Security number, and the IRS generates a new one each year (IRS, Get an Identity Protection PIN). Asking in the letter saves a rejected e-file later.

Organizer answers are tax return information. A preparer who wants to use or disclose that information for another purpose, such as offering a different service, needs the client’s written consent first (26 CFR 301.7216-3, Disclosure or use permitted only with the taxpayer’s consent).

Do not fold that consent into the cover letter. For an individual return, the consent to each disclosure or use must sit on a separate written document, which may be attached to an engagement letter (Rev. Proc. 2013-14, section 5.01 (Internal Revenue Bulletin 2013-3)). A consent covering several uses must let the client select each one (Rev. Proc. 2013-14, section 5.01 (Internal Revenue Bulletin 2013-3)). If you need it, enclose it as its own page.

Many firms send the packet by email with a link instead of a mailed envelope. Keep the email shorter than the letter: the purpose, the return date, the upload link and one line on the IP PIN. Put the full letter in the packet itself.

Protect what comes back. Encryption means the files are scrambled so only the intended reader can open them, and IRS Publication 4557 tells preparers to encrypt sensitive files and emails that carry personal information (IRS Publication 4557, Safeguarding Taxpayer Data). Our follow-up email templates cover the reminders that come after.

• IRS Publication 4557, Safeguarding Taxpayer Data: Preparers should encrypt all sensitive files and emails that carry personal information.
• IRS, Get an Identity Protection PIN: The IP PIN is a six-digit number, and a new one is generated each year.
• IRS fact sheet, Tax deductions for working Americans and seniors: Deductions for tips, overtime, car loan interest and seniors 65 or older apply from 2025 through 2028.
• IRS, Working Families Tax Cuts provisions: From tax year 2026, non-itemizers may deduct up to $1,000 of cash gifts to eligible charities ($2,000 married filing jointly).
• Instructions for Forms 1099-MISC and 1099-NEC: For tax years beginning after 2025 the reporting threshold rose to $2,000.
• 26 CFR 301.7216-3, Disclosure or use permitted only with the taxpayer’s consent: A preparer needs the taxpayer’s written consent before using or disclosing return information for purposes other than preparing the return.
• Rev. Proc. 2013-14, section 5.01 (Internal Revenue Bulletin 2013-3): A consent to each disclosure or use of Form 1040 return information must be on a separate written document, which may be attached to an engagement letter; multiple-use consents must let the taxpayer select each use.
