Your 2027 Busy Season Is Staffed in September, Not January
Capacity for the 2027 filing season is fixed by 2 January. A CPA firm staffing plan for the next eight weeks — what to hire, what to outsource, and what to stop doing.
The extended filing deadline is days away, which makes next busy season the last thing any firm leader wants to think about right now.
That is precisely the problem.
By the time January arrives, your capacity for the 2027 filing season is already fixed. Whatever bench you have on 2 January is the bench you run the season with, because nobody sources, vets, trains and integrates a preparer in three weeks. The decisions that determine how next April actually feels are the ones you make in the next six to eight weeks — while you are heads-down on something else.
The hiring market is not coming to rescue you
The pipeline story has genuinely improved. Most US jurisdictions have now enacted alternative pathways to CPA licensure, trading the extra 30 credit hours for additional supervised experience — the biggest change to licensure in decades, and one that should widen the funnel.
It will not widen it by January. A candidate entering under a 120-hour pathway this year is a licensed CPA somewhere around 2029, and a useful reviewer after that. Meanwhile turnover in public accounting remains high, and roles that go unfilled for two months quietly redistribute themselves onto the people who stayed.
Firms have responded by rebalancing where work gets done rather than waiting for the labour market to turn. Survey work across the profession consistently puts the share of firms using outsourcing, offshoring or both at roughly half — with most of those firms planning to hold or increase that volume.
Read that as a benchmark rather than a bandwagon. If half your peer group has already added an external bench and you have not, you are competing for the same scarce local hires with the same salary bands, and absorbing the same overflow internally.
Work backwards from January
The useful exercise is not "how many people do we need." It is "what has to be true on 2 January."
Eight weeks out. Decide your capacity gap in hours, by workstream — not headcount. How many hours of 1040 prep, business return prep, bookkeeping clean-up and review did last season actually consume, and where did the overtime land? Firms routinely discover the gap is not preparation at all; it is the clean-up work that has to happen before a return can start.
Six weeks out. Choose which workstream leaves the building. The right candidate is high-volume, well-defined and low-judgement — bookkeeping clean-up, standard 1040s, workpaper preparation, data entry from source documents. Review, planning, and anything requiring client judgement stays with you.
Four weeks out. Run a paid pilot on real files, not a demo. Ten returns or three clean-up clients is enough to learn whether the workpapers come back in your format, how many review points come with them, and how the communication actually works across a time-zone gap.
Two weeks out. Lock the workflow: who assigns, what the turnaround commitment is, where files live, what the security posture is, and what "done" means. Document it while nobody is busy, because in February nobody will.
The clean-up bottleneck is the one worth solving
Ask most firm leaders where busy season actually breaks and they do not say preparation. They say the fortnight in February when four clients arrive with books that are not usable, and a senior spends three days recategorising bank feeds at senior rates.
That work is the strongest candidate for an external bench, for three reasons. It is defined enough to hand over cleanly, it is where the hourly-rate arbitrage is largest, and it is the work your own staff most resent doing — which makes it a retention issue as well as a capacity one.
It is also seasonal in a way that hiring cannot match. You need three extra people for eleven weeks, not one extra person for fifty-two.
What to look for, honestly
Not every outsourcing arrangement is worth having, and the failure modes are predictable.
Ask about security posture in specifics: access controls, device restrictions, where data physically sits, and whether the team works in your systems rather than pulling copies out of them. Ask about review structure — a single offshore preparer with no reviewer above them transfers your review burden rather than reducing it. Ask about time-zone overlap, because a question that takes a full day to round-trip in March is a question that does not get asked. And ask what happens in the second week of April when volume spikes.
Then check the reference that matters: a firm of roughly your size that has run at least one full season with them.
The uncomfortable part
Adding capacity does not fix a firm that is taking on work it should not be taking on.
If your realisation on a segment of clients is poor, more preparers is a way to do more unprofitable work faster. September is also the moment to look at the bottom of your client list and decide who is not coming back next year — that is capacity too, and it costs nothing to create.
Do both. Prune the list, then staff the rest properly.
Where we fit
Aimfox runs white-label bookkeeping, clean-up and preparation support for CPA firms across the US and Canada — working inside your systems, to your workpaper standards, with a reviewer above every preparer and overlap into your business hours.
If you want to test it before the season, the sensible thing is a small paid pilot in October: a handful of clean-up clients or a block of returns, run end to end so you can see the workpapers before you commit to anything.
