Every accounting firm knows the shape of its year. January starts fast, February is heavy, March is a blur, and the weeks before the April deadline are something the partners describe in the tone other people use for storms. Then the calls drop off, and summer feels almost quiet.
Google search follows the same shape, only more so. The searches for tax help climb exactly when a small firm has the least time to answer them, and fall exactly when the partners could finally take a first meeting. An account that spends the same way all year is buying its most expensive clicks in the weeks it's least able to use them.
This chapter is about running Google Ads on an accounting firm's real calendar.
"Tax Preparation Near Me" Runs Nine Times Busier in March Than in July
Here's what the last twelve months looked like in Keyword Planner for the US:
- "tax preparation near me": 246,000 searches in March, 201,000 in February, 135,000 in January and April. July: 27,100.
- "cpa near me": 135,000 a month from January through March. May through July: 49,500.
- "tax extension": 201,000 in April. November: 720.
Our example market, Boston, showed the same shape locally: "tax preparation near me" ran 5,400 searches in March and 590 a month from May through August. Your market's numbers will differ. The shape won't.
Two things about that shape matter for the budget. First, the peak brings more competition along with more searches. The national chains lean on this season; in our check of Google's ad archive, one storefront chain's newest Search ad stopped running at the end of May. Second, a small firm's capacity doesn't grow in March. The same partners and the same front desk are handling several times the calls. The searches go up. The firm's ability to answer them doesn't.
Bookkeeping, Payroll and Small Business Searches Keep a Different Calendar
Not every accounting search peaks in tax season. The business side runs on its own clock:
- "small business accountant" peaked at 9,900 searches in August and bottomed at 2,900 in November and December.
- "bookkeeping services" peaked at 33,100 in July.
- "fractional cfo" peaked at 12,100 in July.
- "payroll services" peaked at 22,200 in September.
We didn't verify why each of those lines moves when it does, so we won't guess. What matters for the account is the timing. The searches for recurring monthly work, the bookkeeping and payroll and small business clients that pay the firm all year, run strongest in the months when the individual tax side is quiet. That's good news. The work a firm most wants more of is searched for when the firm has the most room to take it.
A Firm That Can't Answer March Calls Is Paying for Someone Else's Clients
The reviews we read for this guide showed what happens when demand outruns the office. Most complaints about appointments and capacity came from a single chain storefront: rescheduled appointments, long waits, "staffing issues." And one Reddit post says it more plainly than any statistic: "I have called 6 different CPA firms in my area and none of them answer phone calls."
Every one of those unanswered calls started somewhere, and some of them started with an ad. Chapter 3 showed what that does to the math: when the close rate slips from one in three to one in four, the same ads cost a third more per client. In March, the close rate slips because the phones can't keep up, and the ad spend keeps running.
The structure fixes this better than willpower does. Google sets the average daily budget per campaign. So a firm that splits its Search campaigns by service line, individual tax in one, business and bookkeeping in another, can turn one down without touching the other. In the weeks the calendar is full, pull the individual tax budget back and lower its hand bids in Isolation. Leave the business campaign running, because a new bookkeeping client signed in March is still billing in December.
How does a firm know it's full? Not by feel. The front desk log from Chapter 12 answers it. Three signals are worth watching every Monday from February on: calls that went to voicemail and weren't returned the same day, first consultations booked more than two weeks out, and new inquiries the firm turned away or referred elsewhere. When any of the three starts climbing, that's the week to bring the individual tax bids down a step. When they settle, bring them back. It's the same thermostat Chapter 7 described, set by the front desk instead of by the auction.
Two more controls help. An ad schedule limits ads to the hours someone actually answers the phone, which in tax season might mean shorter days than the office keeps. And if a firm switches whole days off, such as Sundays, Google changed how that works in June 2026: a campaign with whole days switched off now paces to the full month's budget, 30.4 times the daily average, across the days it does run. A firm that cuts days to save money should lower the daily budget too, or the remaining days will simply spend more.
Google's Seasonality Adjustment Isn't Built for a Three-Month Season
Google has a feature that sounds tailor-made for this: the seasonality adjustment. It isn't. Google built it to warn automated bidding about a brief spike, a sale lasting a few days at most, and says its effect fades once an event runs beyond two weeks. It doesn't apply to manual bidding at all.
Tax season is three months long, and Isolation runs on manual bids. So the adjustment is the wrong tool twice over. A firm manages busy season the old-fashioned way: with budgets per campaign, hand bids in Isolation that come down when the phones are full, and a calendar note to put them back up in the off-season. Exploration, running on Smart Bidding, will read the seasonal change in its own conversion data over time.
April Brings Two Other Searchers: the Extension and the Tax Bill
The April deadline brings two searches that jump far past their usual level. "tax extension" jumps to 201,000 searches in April, from 720 a month in November and December. "back taxes" jumps to 18,100 in April, from about 2,400 to 3,600 the rest of the year.
These are different jobs from a return. Someone searching for an extension may need a quick filing and a full return later in the year, which can be good off-season work. Someone searching about back taxes may owe the IRS money they can't pay, which is a representation job with its own advertising rules; Chapter 16 covers those.
Decide on purpose. A firm that wants extension work can give it its own ad group, with an ad that says what it costs and when the full return will be done. A firm that doesn't should add the extension searches as negatives before April, so its individual tax budget isn't spent on people who only wanted a form filed.
Bookkeeping Ads, Reviews and a Clean Website Get Built in Summer, Not in March
From May through December, the accounting account gets quieter, and that's the time to make it better:
- Build the business side. New ad groups for bookkeeping, payroll and small business work, timed for the summer and early fall peaks.
- Run Demand Gen, if the firm is ready for it, when there's room to take the calls. Chapter 11 covered why the quiet months are its season.
- Clean up the website. The page audit from Chapter 13 goes on the calendar before January.
- Ask the season's clients for reviews. They just had their return done. Reviews written in May feed the ads written in December.
Then turn it back up, in a set order, in the first two weeks of January:
- Update anything with a price or a year in it. Ads that quote a fee, and the pages behind them, should show this season's numbers. As Chapter 8 covered, a published fee is one the firm may be held to.
- Raise budgets in steps, not all at once. Bring the individual tax campaign back over two or three weeks, as "cpa near me" climbs, so a jump in spend never outruns the phones.
- Restore the ad schedule to the hours the front desk will actually cover in February and March, which may be longer than summer hours or shorter, depending on staffing.
- Re-read last April's search terms before this April arrives. The extension and tax-bill searches that slipped through last year are this year's negatives.
Then watch the front desk as closely as the account. The goal isn't to buy every tax-season click. It's to buy the ones the firm can answer.
Next: Selling IRS Representation Without Google's Debt Rules
Chapter 16 finishes the guide with tax resolution: why "settle your IRS debt for less" can put a firm under Google's debt-services rules, and how to sell IRS representation instead.
