A year-end checklist should tell each type of client what to gather, what to send, and by when, using the firm's own cutoffs, with every IRS date and rule linked to IRS.gov rather than retyped. Separate lists for individual and business clients work better than one long list, and planning ideas belong in the engagement, not in a list everyone reads. Each checklist needs a tax year in its title and an owner who retires it when the season closes.
Late in the year, some CPA firm sites publish a "year-end tax checklist" that mixes three different things: actions the client must take, documents the firm needs, and planning ideas. The planning ideas read like advice to every reader at once, the actions often depend on facts the firm does not have, and the document list, the part clients actually need, is buried at the bottom.
This is checklist planning for CPA firms and other tax practices within the financial, accounting and tax industry. It is not tax advice, and this page deliberately states no deadlines or figures. How dated and evergreen tax pages differ is covered in our page on tax deadline content that stays accurate; this one is about the checklist itself.
A checklist is a request list, not a tax plan
The useful checklist answers one question for the client: what does the firm need from me, and when? Items like "consider accelerating deductions" or "think about a retirement contribution" ask the reader to act on a general idea without the facts that decide whether it fits. A planning idea is not a checklist item. The checklist can still point toward planning by asking for the facts the firm needs: "Tell us by our December cutoff if your income this year will be very different from last year, so we can talk before year end."
That shift does two things. It keeps the page clear of advice, and it turns the checklist into a reason to contact the firm, which is the job a checklist on a firm's website should do.
Split the list by who is reading it
An individual with a brokerage account and a business owner with employees need different lists. The IRS itself splits its calendars this way: Publication 509 "contains 3 tax calendars: general, employer, and excise," which "explain when to file, pay, and take other actions required by federal tax laws." A firm's checklists can follow the same lines, with each list linking to the IRS calendar its reader needs.
| Checklist | Items the firm owns | Where dates and rules come from |
|---|---|---|
| Individual clients | Documents to upload, the firm's cutoff for a meeting, changes to report (move, marriage, new dependent) | Links to the IRS Tax Calendar and to IRS form pages |
| Business clients with employees | Payroll records the firm needs, year-end close timing, contractor information to confirm | Links to the employer calendar in Publication 509 |
| Bookkeeping clients | Reconciliations to finish, receipts to upload, questions to flag before the books close | The firm's own close schedule |
| New clients this year | Prior-year returns, authorizations to sign, portal setup | The firm's onboarding steps |
Own the firm's dates, link the IRS's
Every date on a checklist belongs to one of two owners. The firm's internal cutoffs (when it needs documents, when it stops taking new meeting requests, when it decides on extensions) are the firm's facts and can be stated plainly. IRS dates belong on IRS.gov, where the Tax Calendar invites readers to "view important due dates and actions for key filing deadlines each month," split into quarterly pages.
Mixing the two causes most checklist errors. The tax manager reviewing last year's list can ask, "Which dates on this list were ours, which were the IRS's, and who checked the IRS ones against IRS.gov?" Any IRS date the firm chooses to restate needs a link beside it and a check before the list goes out. Recordkeeping items work the same way: rather than stating retention periods, link to the IRS page that explains "The length of time you should keep a document depends on the action, expense, or event which the document records."
How the checklist reaches clients
Publish the checklist as a web page rather than only as a PDF. A page is easier to read on a phone, easier to link from an email, and easier to update in one place. In our view it also gives search systems and assistants a cleaner source than a PDF built for printing. Offer a printable version if clients want one, generated from the same text.
Put the tax year in the title and the URL, show a "last reviewed" date that reflects a real review, and tell clients how to send what the list asks for. If the firm uses a portal, link to the page that explains it, such as an explanation of how the firm's client portal works. When the season closes, mark the page as past, update it for the next year, or redirect it.
Send it the same way every year. If the checklist goes out by email, the message should link to the page rather than attach a copy, so a client who opens it in February still sees the current version. Whoever sends it should also know which clients get which list, since a business owner who receives only the individual checklist will miss the payroll items entirely.
Fictional example: a CPA firm in Maine
A fictional four-partner CPA firm in Maine has published the same "Year-End Tax Planning Tips" PDF for three years, with a new date on the cover. It carries twenty-five planning ideas and two lines about sending documents. Staff still spend January chasing the same missing forms.
The firm replaces it with four short checklist pages, one per client type in the table above. Each item is tagged as a firm date or an IRS link, and the planning ideas become a single closing section titled "Questions to raise at your year-end meeting," phrased as questions about the client's own situation. The writer should not have to invent the firm's document cutoff or guess whether it files extensions as a routine step; the tax manager supplies both, and the partner who owns individual returns approves the final wording. Each page names its owner in the firm's content log, with a reminder to review it in October.
In Hudson South's process, Authority Asset gathers the firm's approved business knowledge and evidence, including its season calendar and document lists. Hudson Twenty-One records how the firm communicates across 21 dimensions, so a checklist reads like the tax manager's own instructions. Market Intelligence researches what clients in the firm's market ask at year end, and AEO Creation turns those inputs into answer-first content.
