How often should an accounting firm send a newsletter?

Most top-ranked guides on CPA newsletter frequency give you one number—"monthly or quarterly"—and stop. That answer fits a generic SaaS company sending product updates. It does not fit a firm whose entire professional calendar revolves around the IRS Tax Time Guide, the AICPA Tax Section deadline calendar, and the compressed sprint of January 28 through April 15. A flat monthly cadence means thirteen weeks of silence between October and January, then a panicked burst during the most harried stretch of the year.

The answer is part of a broader newsletter strategy for professional service firms, but the cadence question deserves its own page. Chuck McCabe of Peoples Income Tax, writing in Accounting Today, put it directly: “During the off season, a monthly newsletter is probably the ideal frequency. But once tax season starts, consider sending out weekly or bi-weekly newsletters to make sure you are top of mind during your peak season.” The framing is right, but most firms read “off season” as June through December and then scramble. The calendar below maps the right intensity to every month.

The Journal of Accountancy piece on client communication outside busy season puts it plainly: “If we’re not doing it, they’re getting newsletters from other firms.” Practitioners who keep a steady biweekly presence in the off months report that May and June referrals—when competitors go silent after April 15—are disproportionately valuable.

What is the right newsletter cadence during tax season?

Weekly from January 28 (IRS e-file open) through April 15 is the right cadence during tax season. Per Chuck McCabe’s Accounting Today guidance and AICPA Tax Section practice, clients welcome a weekly send when every issue carries a deadline, a document checklist, or an IRS update. Clients are actively scanning their inboxes during this window; the Mailchimp 2024 Industry Benchmarks show Business+Finance at 31.35% open rate, one of the stronger verticals they track.

One nuance generic guides miss: send on Wednesday 7:30 am (client-local time) during January through April, not Tuesday. Tuesday is the day firm staff are buried in incoming client documents and portal uploads. A Wednesday morning send lands in a calmer client inbox window and avoids competing with the firm’s own internal processing noise. For the remaining eight months, Tuesday 8 am is the stronger choice—consistent with Litmus State of Email Engagement data on optimal mid-week send days.

What is the right cadence for the March 16 S-corp and partnership deadline?

S-corp and partnership clients warrant a dedicated send the week of March 10—five days ahead of the March 16 Form 1120-S and Form 1065 deadline. This is the week most individual-filer-focused firms go quiet while entity clients are waiting on confirmation their return is filed. One issue per year anchored to this deadline prevents the call volume spike on March 14 and 15. Structure it as: deadline confirmation, what happens if extension is filed (Form 7004, not automatic payment relief), and a Q1 estimated tax reminder since April 15 is six weeks out.

Should a CPA firm send newsletters during extension season (August–October)?

Weekly the last 30 days only. August is biweekly—ramp language for the 4868 extended filers who are starting to feel the October 15 deadline approach. September goes weekly with September 15 (extended S-corps and partnerships, plus Q3 estimated taxes) as the anchor. October 1, October 8, and October 14 are the three weekly countdown sends. The AICPA extension communication guidance documents that late-extension clients are the segment most likely to miss deadlines without active reminders—and the most likely to generate a complaint or an engagement loss if they do.

How does CPA newsletter frequency compare to financial advisor frequency?

The baseline is identical—biweekly—but the surge windows fall on opposite sides of the year. CPAs sprint hard January through April 15 and September through October 15. Financial advisors surge November through January around year-end planning and tax-form distribution season. GetResponse 2024 Email Marketing Benchmarks (4.4 billion emails analyzed) put Financial Services at 34.70% open rate and 5.34% CTR—the same audience baseline applies to both professions, but the trigger calendar diverges sharply. If you serve both individual filers and advisory-adjacent clients, see the financial advisor cadence page for the advisor-side framing.

What open rate should an accounting newsletter actually expect?

The baseline is 31–35%: Mailchimp 2024 Industry Benchmarks show Business+Finance at 31.35% open and 0.15% unsubscribe. GetResponse 2024 shows Financial Services at 34.70% open with 0.08% unsubscribe. Newsletter-specific GetResponse data shows 40.08% open and 0.12% unsubscribe for finance-themed sends. With basic segmentation—individual filers separated from entity owners—the open rate climbs into the 38–42% band because irrelevant sends stop training the audience to skip. A firm sending one list for dental practice owners, solo freelancers, and real estate investors is leaving 6–8 percentage points of open rate on the table.

How should cadence change for multi-state practices?

Multi-state practices with significant Massachusetts, California, or New York client concentrations should layer state deadlines on top of the federal calendar. Massachusetts follows a September 15 Q3 estimated tax date that aligns with federal. California’s passthrough elective tax election window (June 15) warrants a June issue segment for CA-entity clients. New York’s state-conformity decisions on federal law changes—OBBBA conformity, Section 174 treatment—often lag the IRS by 30–90 days and generate a reactive send opportunity that no generic cadence guide anticipates.

Cadence and segmentation decisions shape what content is appropriate per send—strategy gates content selection. If you are deciding what to write, not just when to send, the newsletter content guide maps content categories to the cadence windows described here.
