Marketing for a CPA and accounting firm lives and dies by the calendar. Your year already has a shape most industries never deal with: a compressed filing season, a quieter summer, extension deadlines in the fall, and a year-end planning window. If your marketing ignores that shape, you end up competing for attention in March when clients have no time to read anything, then going silent in the months when they are actually ready to choose a new firm.

This article shows you how to build an annual marketing calendar and cadence that matches how accounting work really flows. You get a month-by-month structure, a planning table you can copy, the compliance points to keep in view, and the mistakes that quietly waste a small firm’s marketing hours. By Christoph Olivier.

What a marketing calendar actually is for an accounting firm

A marketing calendar is a written plan that maps what you will publish, send, and promote across the year, tied to dates and to the person responsible for each item. For a CPA firm it is less about chasing trends and more about showing up consistently around the moments when clients and prospects have a tax or accounting question on their mind.

Two ideas drive it: seasonality and cadence. Get both right and the plan mostly runs itself. Get either wrong and you either burn out your team or fade into the background.

Seasonality

Your demand is not flat. Individual clients think about you near filing deadlines. Business owners think about you at quarter close, at year-end, and when they are choosing a new firm, which often happens right after a frustrating season with their current one. A good calendar puts heavier client communication before and during those windows, and heavier prospecting in the gaps where owners actually have time to talk.

Cadence

Cadence is the steady rhythm you keep no matter what: a monthly newsletter, a weekly social post, a quarterly client webinar. Cadence is what keeps you visible in the slow months, so you are already familiar when someone is finally ready to switch firms. Seasonality tells you what to say; cadence makes sure you keep saying something. One without the other leaves a gap a competitor can walk into.

A month-by-month framework you can run

Build your calendar around the accounting year, not the generic marketing year. Here is a workable structure for a US firm. Adjust it for your client mix, since a firm heavy in business advisory will lean into planning windows more than a firm built mostly on individual returns.

To make the table real, do three things. Assign an owner to every row, even if that owner is you, so nothing falls through. Block production time in the quiet months, because summer is when you build the fall and winter assets rather than rest on them. And batch your content: write a quarter of newsletters or social posts in one sitting instead of scrambling each week.

Keep it realistic

A solo or small firm cannot run every channel well. Pick two or three you can sustain across a full year. For many accounting firms that means email, one social platform, and either search-focused content or a structured referral program. An overbuilt calendar that no one maintains is worse than a simple one you actually run, because a stalled plan trains your audience to expect silence from you.

Set a review point

Put one recurring meeting on the calendar, monthly or quarterly, to check what shipped, what slipped, and what a single number told you, whether that is new inquiries, newsletter replies, or booked calls. The plan is a draft you correct through the year, not a document you file and forget. When a month gets away from you during busy season, the review is where you decide what to drop and what to move rather than letting the whole plan stall.

Compliance and the mistakes to avoid

Accounting marketing sits under professional conduct rules, so keep your calendar inside them from the start. This is general marketing guidance, not legal advice, and you should confirm specifics with your state board and your own counsel.

The AICPA Code of Professional Conduct addresses false, misleading, or deceptive promotion in the 1.600 series, so every promise, comparison, and claim you schedule needs to be accurate and supportable. The confidentiality obligations in the 1.700 series mean client information cannot appear in your marketing without permission, which shapes how you handle case studies, testimonials, and any mention of a client by name. Some state boards further restrict or prohibit testimonials and endorsements, so check your state before you build a review campaign into the calendar.

• Going dark during busy season and never restarting. Many firms stop marketing in January and forget to switch it back on in May. Schedule the restart date now so it is not a decision you have to remember later.
• Publishing client details without written consent. A named case study or a screenshot of a client’s numbers can breach confidentiality. Get permission in writing and anonymize the details that are not essential.
• Building a testimonial campaign your state board bars. Confirm the rules where you practice before you make reviews or endorsements a calendar staple.
• Promising specific tax savings or guaranteed outcomes. Keep claims accurate and general. Avoid guaranteed-refund or guaranteed-savings language anywhere on the calendar.
• Overloading the plan. Ten channels and one part-time person collapse by March. Right-size the calendar to the hours you truly have.

How the calendar fits your wider marketing

The calendar is the operating layer, not the strategy itself. It only works when it sits on top of clear positioning, a defined ideal client, and channels chosen on purpose. If you have not set those yet, start with a full marketing plan for CPA and accounting firms and let the calendar schedule the work the plan defines. The plan decides what matters; the calendar makes sure it happens across the whole year.

You do not need a bigger budget to grow an accounting firm. You need a plan that respects your season and a cadence you can keep. Map your year once, give every piece an owner, and protect production time in the quiet months.

Frequently asked questions

When should an accounting firm start planning its marketing calendar?

Ideally in the fall, before year-end planning and the next filing season. Building it in the fourth quarter lets you line up client communication for deadlines and schedule the post-season restart before you get buried in returns.

How often should a CPA firm publish or send marketing content?

Set a cadence you can hold all year. A monthly client newsletter plus a weekly or biweekly social post is realistic for most small firms. Consistency matters more than volume, especially through the slow months.

What should be on the calendar during tax season?

Mostly client-facing, service-oriented communication: document checklists, deadline reminders, status updates, and answers to common questions. Heavy prospecting rarely lands when clients are busy, so keep new-business pushes light until May.

Can I put client testimonials on my marketing calendar?

Only after checking your state board, since some restrict or prohibit testimonials, and only with written client consent given the AICPA confidentiality rules. Confirm both before you schedule any review or endorsement campaign.

How many marketing channels should a small accounting firm run?

Two or three you can sustain. Email plus one social platform plus either content and search or a referral program covers most firms without overwhelming a small team. Add channels only after the first ones run smoothly.

What is the difference between a marketing plan and a marketing calendar?

The plan defines your positioning, audience, offers, and channel choices. The calendar schedules the specific actions across the year. The plan decides what to do; the calendar decides when it happens.
