Year End Tax Planning Checklist: The December Client Outreach Small Firms Can Run

December outreach for a 1 to 5 person firm is a short question list, not a strategy deck. Segment the list. Ask what changed. Book a call only when the answers show a change. Log what they tell you so the return does not start from a guess. Point them to IRS pages for limits. Do not pick a strategy for them on this page.

Quarterly payment reminders are estimated tax payment reminders. Owner pay for S corporations is the S corp reasonable salary review. W-2 facts you still need from payroll clients are the year end payroll W-2 checklist. The January document list is the tax document checklist for clients.

Outreach is a list, not a strategy memo

You are collecting facts for the file. This page is a client outreach process, not tax advice and not a strategy memo. You are not telling them to harvest losses, convert a Roth, or buy equipment. Those decisions belong on a call with the practitioner who will sign the return, using the current IRS pages, not a December email.

Admin sends the question list and logs replies.
The practitioner books time only for clients whose answers show a change.
Limits, ages, and due dates come from the IRS pages linked here. They change. Do not paste last year's numbers into the email.

Segment the list first

One email to everyone produces noise. Four short lists produce answers you can file.

Segment	Why they are on this list	What you ask extra
W-2 only	Wages and withholding. Little unwithheld income last year.	Job change, second job, marriage or a child, home purchase. Point them at the Tax Withholding Estimator.
Self employed	Schedule C, partnership, or gig income. Estimates last year.	Whether this year's income is up or down, and whether each estimated payment is on the log. Point them at IRS Estimated taxes.
Retirees with RMDs	IRA or workplace plan that has a required minimum.	Whether this year's RMD is taken or still due. Point them at the IRS RMD page for the age, the deadline, and the worksheet. Do not type a dollar amount.
Business owners	S corporation, partnership, or a shop with payroll.	Income change, estimates, and whether owner wages and W-2 facts are already in process. Salary is the S corp page. W-2s are the payroll page.

The client question list

Send this in the first or second week of December. Ask them to reply by a date you pick. If a line does not apply, they write "none."

Subject

[Year] December questions for your [Year] return

Hi [First name],

We are gathering facts for your [Year] return. This is a question list, not tax advice. Reply to each line by [Date]. Upload support in the portal at [Link].

1. Income changes this year: new job, lost job, sale of an asset, retirement, or a new side activity. Name it, or write none.

2. Estimated tax payments this year: amount, date paid, and confirmation. If you are not sure you need estimates, read IRS Estimated taxes. Do not guess a number in this email.

3. Retirement contributions you already made or still plan to make for [Year]. Limits are on IRS IRA contribution limits (and the linked page for other workplace plans). We will not quote a limit here because it changes.

4. Required minimum distributions: taken, still due, or does not apply. Age, deadline, and how to compute the amount are on IRS required minimum distributions. Do not type a dollar amount in this reply unless it is what you actually withdrew.

5. Withholding: if you have a W-2 or a pension, run the IRS Tax Withholding Estimator and tell us if you will give your employer a new Form W-4. The IRS says to check withholding every January and after a major life change (new job, income change, marriage, divorce, a child, a home purchase).

6. Records you are holding that we do not have yet (closing statement, K-1 you are waiting on, a 1099). Name the item and a date you expect it.

If nothing changed, write "no changes" and skip the call. If something on this list changed, we will send a time to talk. We will not use this email to pick a strategy for you.

Book calls only when answers show a change

A W-2 only client who writes "no changes" does not need a December meeting. A self employed client whose estimates are missing, or a retiree who has not taken an RMD that the IRS page says is due, does.

Reply you got	Next step
No changes, W-2 only	Log it. No call. Organizer still goes out on the usual date.
Income change named	Practitioner call. Take facts. Do not email a strategy.
Estimates missing or amounts unknown	Send them back to the estimated tax page and to your payment log. Call if they still cannot reconstruct the year.
Retirement contribution planned, they want a number	Point at the IRS limit page. The practitioner can talk through facts on a call. This guide does not.
RMD not taken and they are in the RMD segment	Point at the IRS RMD page. Book the practitioner. Do not compute the RMD in the reminder email.
They ask 'should I ...'	That is a call. Not a reply to the whole thread with a tactic.

Log the answers for the return

The value of this exercise is a note on next year's return, not a warm feeling that you sent a newsletter. Drop each answer on the client: income change, estimates with confirmations, contribution plans with a link to the IRS limit page, RMD status with a link to the IRS RMD page, W-4 change yes or no.

Admin files the reply PDF or portal message on the client the same day.
Blank lines after the deadline get one named chase, then a call.
The return preparer reads this log before they key January documents. A surprise K-1 in March is what you were trying to see in December.
