What's a Good Cost Per Lead for Accounting and Tax Firms on Google Ads?

A good cost per lead for accounting and bookkeeping firms on Google Ads in 2026 is $35-$60 for general services, while specialized tax preparation leads run higher, at $60-$120. Tax-specific costs are also seasonal: expect CPL to climb toward the $120 end during tax season (January through April) and settle closer to $67 or lower in the off-season.

Why Tax Prep Costs More Than General Accounting

Tax preparation keywords carry higher cost-per-click than general accounting terms — tax-specific search terms average $8.84 CPC against $4.44 CPC for accounting broadly, according to 2026 industry benchmark data, while narrower services like bookkeeping run cheaper still, around $8 CPC. The higher CPC on tax terms reflects concentrated demand within a few months of the year, when every local firm is bidding for the same searchers at once.

Conversion Rate Partly Offsets the Higher Click Cost

Tax-specific services convert at roughly 7.2% on Google Ads — nearly double the cross-industry average conversion rate. That higher conversion rate is part of why tax prep's CPL doesn't scale linearly with its higher CPC: a firm paying nearly double the click cost of general accounting isn't necessarily paying double for a lead, because a larger share of those clicks convert.

Seasonality Is the Biggest Lever, Not Targeting

The single biggest driver of tax-prep CPL swings isn't audience or keyword strategy — it's the calendar. Every firm targeting "tax preparer near me" or similar terms is bidding hardest in the same eight-to-ten week window, which pushes CPCs and CPLs up together during tax season and lets them fall back once the deadline passes. Firms that shift budget toward general accounting and bookkeeping services in the off-season, rather than holding a flat tax-prep budget year-round, typically get a better blended CPL across the full year.

Local Services Ads as a Lower-Cost Alternative

For firms eligible for Google's Local Services Ads (pay-per-lead rather than pay-per-click), reported costs run considerably lower — commonly cited in the roughly $15-$50 per lead range in markets where LSA supports accounting and tax categories, though availability varies by region and Google periodically changes which professional categories qualify.

What This Means for Budgeting Across the Year

A firm that spreads one flat monthly Google Ads budget evenly across twelve months is effectively overpaying in the off-season and underbidding during tax season, when competitors are willing to pay up to $120 per lead and a flat, lower bid gets outcompeted for impressions. Reallocating a larger share of annual budget into January through April, and shifting the rest toward general accounting and bookkeeping campaigns the remaining eight months, tends to produce a better blended CPL than holding one number constant year-round.

Bottom Line

Budget $35-$60 per lead for general accounting and bookkeeping campaigns year-round, expect tax-prep-specific campaigns to run $60-$120 and to peak near the top of that range during tax season, and check whether Local Services Ads is available in your market before committing a full budget to standard search campaigns.
