Rippling vs Gusto for a CPA Firm's Tax Season Surge

Before evaluating any platform, write down how many people you actually add each January, how many states they're in, and how many of them leave by the end of May. Firms often underestimate this because the swing feels routine after doing it for years, but a firm that goes from twenty to thirty people, three of them in states you don't otherwise operate in, has meaningfully different onboarding and tax registration needs than one that stays in a single state year-round.

This exercise usually surfaces a second, less obvious variable too: how many of those seasonal hires are returning preparers versus brand new ones. A firm that rehires the same fifteen people every January has an onboarding problem that mostly repeats itself and can be streamlined once. A firm recruiting fresh seasonal staff every year is solving that same onboarding problem from scratch each time, which changes how much setup investment in a more structured platform is actually worth.

Many states require a final paycheck on the employee's last day or within a short, specific window, sometimes stricter than your standard payroll cycle allows for. Get this wrong at scale, releasing ten seasonal preparers over two weeks without accounting for each state's rule, and you're looking at penalty exposure across multiple jurisdictions at once, right when the firm's own attention is on closing out busy season, not compliance research.

This is also where classification questions tend to surface. A firm scrambling to release fifteen seasonal preparers in the same week sometimes reaches for a shortcut, converting someone to a short 1099 engagement for their final weeks rather than running a proper final paycheck. That shortcut usually creates more risk than it avoids, since a worker treated as an employee all season doesn't become a contractor just because the engagement is ending, and reclassifying them that way invites exactly the kind of audit exposure the firm was trying to sidestep.

Gusto's straightforward setup is a real advantage here: adding a batch of seasonal preparers in early January, when the firm's own attention is split between hiring and its first wave of client work, benefits from a platform that doesn't require configuration decisions in the moment. Rippling's more structured onboarding, defining roles, access, and device needs upfront, pays off more if your seasonal hires need access to the same client systems your year-round staff do, since that access needs to be provisioned and then reliably revoked in May without anyone forgetting.

ADP TotalSource makes more sense for the stable core of a firm, the partners, managers, and year-round staff, than for a fluctuating seasonal population, since co-employment relationships aren't designed around headcount that doubles for four months and then contracts. Firms that use a PEO here typically run it for their permanent staff's benefits and HR compliance while handling seasonal hiring through Gusto or Rippling directly, rather than trying to fit the whole swing into one co-employment relationship.

Whatever platform you choose, budget realistically against the market rate for the accountants and auditors you're bringing on. National wage data puts the median annual pay for accountants and auditors at $83,680, with the top quartile above $109,810¹, and seasonal or contract rates for tax season specifically often track toward the higher end given the compressed timeline and demand. A platform that saves you a few hours of admin work each week isn't the lever that matters most here, staffing at a competitive rate for the season is.

It's worth running that comparison explicitly before busy season starts: take last year's seasonal payroll total, add whatever platform fee you're considering, and compare it against what a two or three point rate increase would cost to stay competitive for the preparers you're trying to attract. Firms that treat the platform decision and the pay-rate decision as separate conversations often end up underpaying for talent while overpaying for administrative convenience, which is the opposite of where the budget should go during the season that matters most.

Before you commit to a platform, confirm these points:

• Your seasonal curve: how many people you add each January, in how many states, and how many leave by the end of May.
• Final paycheck rules in each state where seasonal staff work, since some require payment on the employee's last day.
• Onboarding speed for a batch of seasonal preparers in early January, when the firm's attention is split with client work.
• Whether a PEO fits only your year-round core, with seasonal hiring run through separate payroll software.
