It is January. Returns are starting to pile up. Your staff is bracing for 60 to 70 hour weeks that will last through April. That experienced senior accountant you were counting on just gave two weeks notice because a tech company offered 30 percent more money and no busy season. And you are doing the mental math on how many extensions you will need to file because you simply do not have enough hands.
This is not a planning failure. It is a structural problem. CPA firms need twice the capacity from February through April that they need from June through September. No permanent staffing model solves that cleanly. The question is which approach to surge capacity costs you the least, delivers the best quality, and leaves your permanent staff intact at the end of it.
We have helped CPA firms through dozens of tax seasons at Madras Accountancy. We have seen all three approaches work, and we have seen all three fail. Here is the honest breakdown. For a broader look at how offshore teams handle tax season, our conquering tax season guide covers the operational details.
Hiring seasonal staff through staffing agencies or direct recruitment is the traditional approach. You bring on 2 to 4 temporary preparers in January, they work through April 15, and they leave.
What it costs for a 10-person firm adding 3 temps: Staffing agencies charge $35 to $55 per hour for experienced tax preparers, which includes the agency's margin. For 3 temps working 50 hours per week for 12 weeks (February through April), that is 1,800 billable hours at roughly $45 per hour average. Total cost: approximately $81,000. If you hire directly (avoiding the agency fee), the cost drops to $50,000 to $65,000 in wages and employer taxes, but you absorb the recruiting time and risk.
The real problem is not the cost. It is availability. The accounting talent shortage means experienced seasonal tax preparers are scarce. The good ones get booked in October. By January, what is available tends to be less experienced, less reliable, or both. We hear from firms every February saying "we tried to hire temps but could not find anyone qualified."
The onboarding burden is real. Even an experienced temp needs time to learn your firm's processes, your software setup, your review preferences, and your client base. Budget 1 to 2 weeks of reduced productivity while the temp gets up to speed. For a 12-week engagement, that is 8 to 16 percent of their time lost to onboarding. And next January, you start over with a new temp who needs the same onboarding.
When this works: You have a relationship with a staffing agency that knows your firm and reserves quality candidates for you. You start recruiting in October, not January. Your work is straightforward enough that a temp can be productive within a week.
When this fails: You wait until January to start looking. The available talent pool is thin. Your client base includes complex returns that take weeks to learn.
This is what we do at Madras Accountancy, so we know this model inside out. An offshore team prepares draft returns in your tax software, working under your firm's review process. Your onshore CPAs review, adjust, and sign off.
What it costs for a 10-person firm adding offshore capacity: An offshore team of 3 preparers at $1,500 per month each costs $4,500 per month. For a 6-month engagement (October through March, including ramp-up), that is $27,000. If you use per-return pricing instead (which we recommend for seasonal engagements), 300 individual returns at $65 average is $19,500, plus 75 business returns at $150 average is $11,250. Total: approximately $30,750.
The advantage is year-over-year continuity. Unlike temps who leave and never come back, your offshore team is available next tax season with the institutional knowledge they built this year. They already know your clients, your processes, and your review preferences. Season two is dramatically more efficient than season one.
The 24-hour workflow advantage. Because of the time zone difference, your offshore team works while your office is closed. You assign returns at 5 PM Eastern, the team in Chennai prepares them overnight, and they are in your review queue at 8 AM the next morning. This effectively doubles your daily throughput without anyone working overtime. We covered this in detail in our time zone advantage guide.
The disadvantage is the ramp-up. If you are starting an offshore engagement for the first time in January, you are already late. The first 90 days with an offshore team require investment in training, process documentation, and quality review. Starting in October gives you a productive team by January. Starting in January means you will not hit full productivity until late February.
When this works: You plan ahead and start onboarding in October or November. Your returns are organized enough that an offshore team with US GAAP training can prepare them from source documents. You have a senior team member who can dedicate 5 to 10 hours per week to managing the offshore relationship.
When this fails: You try to start in February, have undocumented processes, and expect the offshore team to figure everything out on their own.
The default for most firms. Push your existing staff to work 55 to 70 hour weeks from February through April. Offer overtime pay or bonuses. Hope nobody quits.
What it costs for a 10-person firm running heavy overtime: Assuming 5 staff members working an extra 15 hours per week for 12 weeks at an overtime rate of $45 to $65 per hour (1.5x their regular rate). That is 900 overtime hours at $55 average. Total: approximately $49,500 in direct overtime cost. But the real cost is much higher.
The hidden costs of overtime are what kill firms. Burnout-related turnover costs $50,000 to $100,000 per senior departure (recruiting, onboarding, lost productivity). Error rates increase by 20 to 40 percent after the 50th hour per week according to multiple studies. Client satisfaction drops when your exhausted staff is slow to respond and more likely to make mistakes. And the staff retention problem compounds year after year because each brutal tax season makes it harder to keep good people.
The morale impact compounds silently. We talk to CPA firm staff who have survived 10, 15, even 20 tax seasons of 65-hour weeks. They are not heroic. They are exhausted. And every year, the calculation in their head changes slightly: "Is this worth it?" At some point, the answer changes, and they leave. Usually for an industry role that pays 85 percent of the salary with zero overtime and no busy season. The firm loses 15 years of institutional knowledge because it would not invest in surge capacity.
When this works: Honestly, it does not work well for anyone long-term. It is the fallback when you have not planned ahead. Short-term, it gets returns out the door. Long-term, it erodes your team and your firm's culture.
In our experience, the most effective busy season strategy is not choosing one option. It is combining offshore capacity with a sustainable overtime level that your staff can handle without burning out.
The hybrid model works like this. Your offshore team handles the volume production work: straightforward 1040s, 1065s, and 1120S returns that follow predictable patterns. Your onshore team focuses on complex returns, client communication, and review. Instead of 65-hour weeks, your onshore staff works 50 to 55 hours. Still more than normal, but sustainable for 12 weeks.
The math on the hybrid approach for a 10-person firm: offshore team cost of $27,000 to $31,000 plus moderate overtime (5 staff at 10 extra hours per week for 12 weeks at $55 per hour) of $33,000. Total: $60,000 to $64,000. That is less than temps ($81,000), comparable to heavy overtime in direct cost ($49,500) but dramatically cheaper when you include the hidden costs of burnout and turnover.
For a 10-person CPA firm that needs to process 300 individual returns and 75 business returns during tax season, here is the direct cost comparison.
Temporary hires (3 temps, 12 weeks): $65,000 to $81,000 in direct cost. Plus $5,000 to $10,000 in management time for onboarding and supervision. Quality is variable. No carryover knowledge to next season.
Offshore team (3 preparers, 6-month engagement): $27,000 to $31,000 in direct cost. Plus $8,000 to $12,000 in onshore review and management time (higher in year one, drops in year two). Quality improves year over year. Full knowledge carryover.
Overtime (5 staff, 12 weeks of extra hours): $49,500 in direct overtime cost. Plus $50,000 to $100,000 in potential turnover replacement cost if one senior leaves. Error rate increases. No new capacity added.
Hybrid (offshore plus moderate overtime): $60,000 to $64,000 in total cost. Sustainable workload for onshore staff. Continuous improvement year over year. Lowest risk of turnover.
The offshore model costs 40 to 60 percent less than temps and carries knowledge forward. The only scenario where temps make more sense is when you have a one-time surge (like absorbing another firm's clients during a merger) that you know will not repeat.
Regardless of which approach you choose, the planning timeline is the same. The firms that have smooth tax seasons are the ones that start planning in the summer.
July through September: Evaluate this past season. What worked? What broke? How many extensions did you file? Did anyone quit? Use these answers to size your capacity gap for next year.
October: If you are going offshore, start the onboarding now. If you are going with temps, contact your staffing agency and reserve candidates. If you are relying on overtime, start the honest conversation with your staff about what the season will look like and what support (bonuses, comp time, flexible schedules post-April) you are offering.
November through December: Run pilot work with your offshore team. Have them prepare a batch of extension returns or prior-year amendments to build familiarity with your process before the volume hits in January.
January: All hands on deck. Your capacity plan is in place, your surge resources are trained, and your team knows the plan. The firms that start planning in January are already behind.
Start with offshore. Even if you are reading this in January and it is already late for this season, begin the relationship now. Run a pilot engagement with a small batch of returns. Accept that this season will be rougher than optimal. But by next October, you will have a trained team ready to handle the volume, and you will never face the January staffing scramble again.
If you want to talk about what busy season support would look like for your firm, including whether it makes sense to start mid-season, reach out at madrasaccountancy.com.
Yes, but with realistic expectations. We do mid-season onboarding at Madras for firms that need immediate help. The first 2 to 3 weeks are an accelerated ramp where we handle simpler returns while learning your processes. By week 4, we are handling the full range of returns your firm prepares. You will not get the same efficiency as a team that started in October, but you will get meaningful capacity relief within a month.
Freelance CPAs and EAs are another option, typically charging $50 to $100 per hour. The risk is reliability. A freelancer who gets a full-time offer in March may disappear mid-season. You have no backup, no institutional support, and no recourse. For a handful of complex returns that need senior-level expertise, freelancers can work. For volume capacity, they are less reliable than either staffing agencies or offshore teams.
Your clients should never interact with temporary staff or offshore teams directly. All client communication goes through your permanent onshore team. The surge capacity (whether temps, offshore, or overtime) handles production work behind the scenes. Your client experience does not change.
Ideal is 90 days before peak volume (October start for January peak). Minimum viable is 30 days. Below 30 days, you are asking the offshore team to learn your processes while handling live returns, which increases error rates and review time. If you are planning for next tax season, start the conversation now.
The same way your onshore team does. The offshore preparer identifies the missing information, documents what is needed, and sends a request back to your onshore team. Your onshore team contacts the client, gathers the document, and uploads it for the offshore preparer to complete the return. The client never interacts with the offshore team directly.
Transitioning existing clients to an outsourced CAS team is operationally straightforward and emotionally tricky. Here is how to do it without losing clients.
Your first outsourced tax season will either be a relief or a disaster. The difference is whether you start preparing in October or panic-call a provider in February.
CPA firms are terrible at collecting their own invoices. Average days in AR is 65 days. Here is how outsourcing AR management cuts that to 40 and improves cash flow.
