During tax season, every hour you spend on scheduling is an hour you’re not billing at $150-$400. Here’s what CPA firms actually pay for EA support, and what the return looks like.
EA costs for accounting practices vary more than general VA pricing because the role carries specific skill requirements, seasonal demand patterns, and workflow complexity that general admin support doesn’t. An EA who can track client document deadlines, manage portal communications, and coordinate around extension seasons costs more than a general scheduler, and for good reason. This article covers the actual numbers across hiring models, what drives costs up or down, and how to calculate whether the investment pays for itself in your practice.
Key Takeaways
- Virtual executive assistant costs range from $15K-$24K annually for offshore and $55K-$75K for US-based, before benefits and overhead.
- The Philippines offers the best combination of cost, English proficiency, and professional experience for offshore EA talent.
- Hourly, retainer, and full-time pricing models fit different workload patterns, with full-time providing the best per-hour cost at scale.
- Budget for onboarding time, software costs, and management overhead in addition to the EA’s base compensation rate.
- Calculating ROI requires knowing the value of a founder’s hour and the weekly time an EA can realistically recover.
What CPA firms actually pay for executive assistant support
In-house EA salary benchmarks for accounting firms
PayScale data on accounting administrative assistants puts the hourly range at $14-$46, with an average around $22.87 per hour. On an annual basis, Bureau of Labor Statistics wage data for administrative support in professional and business services places accounting admin assistants in the $38,000-$56,000 range for most markets. Add 25-30% for benefits, payroll taxes, and employer costs, and an in-house EA at the midpoint of that range costs $52,000-$73,000 annually all-in.
Specialized tax administrative roles, meaning EAs with verified software proficiency and prior accounting firm experience, can run significantly higher. NSA benchmarking data for small CPA firm staffing shows that accounting-trained administrative support commands a notable premium over general admin hires, particularly during peak hiring periods when competition for experienced candidates increases.
Virtual EA costs for CPA practices
US-based virtual EA services through established agencies run $2,000-$5,000 per month for dedicated support, depending on hours needed and service level. This tier covers EAs with professional backgrounds and reliable availability, but doesn’t specifically address accounting workflow familiarity unless the provider specializes in professional services.
For general how much does a virtual executive assistant cost context, standard virtual EA retainers run $900-$3,500 per month depending on hours and geography. For CPA firms, budget toward the higher end of any given tier to account for the skill and industry familiarity premium that accounting workflows require.
Offshore EA rates for accounting workflows
Offshore EAs in the Philippines with accounting firm experience run $700-$2,000 per month for full-time arrangements, according to Outsource Accelerator’s offshore staffing data for professional services. The executive assistant salary philippines benchmarks for mid-level EAs with international client experience put monthly rates at ₱35,000-₱55,000 ($600-$950 USD), with accounting-specific experience adding a 15-25% premium above base market rates.
At $1,200-$1,800 per month through a managed offshore provider, CPA firms access EA support that costs 60-70% less than a comparable US-based in-house hire, even after accounting for the management and oversight structure included in managed arrangements.
Factors that affect EA costs for CPA firms
Tax software proficiency premiums
EAs with verified experience in Drake Tax, UltraTax CS, Lacerte, ProConnect, or CCH Axcess command meaningfully higher rates than general admin candidates. The premium reflects the reduced training time and error risk that comes with prior software experience. Onboarding an EA who already knows how to navigate client portals, pull prior-year returns, and track engagement letter status takes days instead of weeks.
Budget a 15-25% premium above base EA rates for verified tax software proficiency. That premium typically pays for itself within the first two weeks of tax season, when an experienced EA can operate with minimal oversight while a newly trained one requires constant direction.
Seasonal vs. year-round arrangements
CPA firms face a choice between year-round retainers with consistent monthly costs and seasonal arrangements that ramp up during tax season and extension season. Year-round arrangements at $1,200-$1,800 per month (offshore managed) or $2,000-$3,500 per month (US-based virtual) provide continuous EA access and eliminate ramp time at the start of each season. The EA builds institutional knowledge over the full year rather than re-learning your systems each January.
Seasonal arrangements can cost 10-20% more per hour during peak periods because demand outpaces supply of experienced accounting-familiar EAs in Q1. A firm that tries to engage EA support in late January, after tax season is already underway, often pays more and gets less experienced candidates than firms with standing arrangements.
General admin vs. accounting-trained support
A general administrative EA handles calendar management, email drafting, and document organization competently without any accounting background. An accounting-trained EA handles all of that plus deadline tracking across tax calendars, IRS notice coordination, client portal management, and workflow-specific document collection. The gap in capability matters most during peak periods when the volume of client-facing coordination spikes.
Most CPA firms with fewer than five staff find that a well-trained general EA, supported by clear process documentation, can handle 70-80% of accounting-specific administrative tasks after a 30-60 day onboarding period. Firms with more complex workflows or high client volumes typically need an EA with prior accounting firm experience from day one.
Budgeting for tax season: surge pricing and ramp-up costs
Full-year retainer vs. seasonal engagement
The math on full-year vs. seasonal arrangements depends on how many months of the year you actually need intensive EA support. Most CPA firms have three distinct demand periods: January-April (primary tax season), August-October (extension season), and November-December (planning and year-end). That’s roughly seven months of elevated demand against five months of lighter administrative work.
At $1,500 per month for a year-round offshore EA arrangement, the annual cost is $18,000. A seasonal arrangement covering seven months at $2,000 per month (accounting for the premium and ramp cost) runs $14,000 annually, but with the added cost of re-onboarding at the start of each engagement and the availability risk of not having a standing arrangement when you need one most. Many firms find the full-year retainer easier to manage even if the seasonal math looks favorable on paper.
What to expect during January-April peak
Primary tax season requires an EA who can operate with minimal daily oversight. Client document collection, deadline reminders, portal uploads, scheduling around preparer availability, and client communication volume all spike simultaneously. An EA who needed heavy direction in November becomes a bottleneck in February if they haven’t been developed throughout the year.
The how to hire a virtual executive assistant process for a CPA firm should begin no later than October if you want an EA who’s ready to handle tax season volume independently by January. That timeline allows 60-90 days of onboarding, process documentation, and supervised execution before the full load hits.
Planning for extension season (August-October)
Extension season is a secondary peak that many firms underplan for. September 15 and October 15 deadlines create a compressed surge of client coordination, document gathering, and status communication that mirrors January-April in intensity, even if shorter in duration. Firms with year-round EA arrangements absorb this surge without disruption. Firms relying on seasonal engagements often scramble to re-engage EA support on short notice.
Calculating EA ROI for your practice
The billable hour recovery framework
CPA Trendlines billing rate data puts the typical CPA hourly rate at $150-$400, with experienced practitioners in mid-market firms commonly billing $200-$350. An executive assistant ROI calculation for an accounting practice starts with one question: how many billable hours per week are you losing to administrative tasks that an EA could handle?
For most CPA firm owners spending 8-12 hours per week on scheduling, client follow-up, document chasing, and administrative coordination, the calculation is straightforward.
Sample ROI calculation for a 5-person firm
Here’s what the math looks like for a five-person CPA practice with an average partner billing rate of $250 per hour:
- Hours lost to admin tasks per week: 10
- Weekly opportunity cost: $2,500
- Monthly opportunity cost: $10,000
- Offshore EA cost (managed, full-time): $1,500 per month
- Hours recovered per week (accounting for onboarding and oversight): 8-10
- Monthly billable hours recovered: 32-40
- Monthly revenue recovered at $250/hour: $8,000-$10,000
- Net monthly benefit after EA cost: $6,500-$8,500
The breakeven point is six recovered billable hours per month at $250 per hour. At a $1,500 monthly EA cost, recovering six hours more than covers the investment. Most CPA firms with documented processes see breakeven within the first four weeks of a fully onboarded EA.
When the investment pays for itself
The investment pays for itself faster in practices with higher billing rates and more concentrated administrative burden on the senior staff. A solo practitioner billing at $300 per hour who spends three hours per week on scheduling breaks even on a $1,500 monthly EA cost in about two weeks of that recovered time converting to billable activity.
Managing the EA relationship well matters as much as the initial hire. The giving feedback to offshore EA process and the work of building trust with remote EA support are the variables that determine whether the ROI is captured in practice or just on paper.
Choosing the right EA model for your firm size
Solo practitioners and 2-3 person firms
At this firm size, a part-time offshore EA arrangement (20-40 hours per month) at $450-$900 per month typically covers the full administrative load without overpaying for unused capacity. The tasks that consume the most time for solo practitioners, client scheduling, document requests, portal management, and deadline reminders, don’t require full-time support if the workflows are documented clearly.
Decision factors to consider at this scale:
- Whether your administrative burden is consistent enough month-to-month to justify a retainer over hourly billing.
- Whether you have the process documentation in place to delegate effectively from day one, or whether you’ll need to build it during onboarding.
- Whether you need availability during business hours or can work asynchronously with an EA in a different time zone.
Mid-size practices (4-10 staff)
Practices in this range typically need 40-80 hours of EA support per month, putting them squarely in the full-time offshore EA range at $1,200-$1,800 per month managed, or $2,000-$3,500 per month for US-based virtual. The higher administrative volume at this firm size, combined with the higher cost of senior partner time, makes the ROI case for full-time EA support the strongest of any firm size category.
Accounting-trained EA experience matters more at this scale because the volume of accounting-specific coordination, portal management, deadline tracking, and client communication requires an EA who can operate independently across multiple workstreams without daily direction.
Growing firms planning to scale
Firms planning to add staff or expand services in the next 12-24 months should build EA support infrastructure before the growth curve hits, not after. An EA who’s embedded in your workflows during a growth phase documents processes as they’re built rather than retroactively, which reduces the operational friction of adding staff later. The cost of an EA during a growth phase is the same as during steady-state operations, but the return on that investment compounds as the firm scales.

FAQs about CPA firm EA costs
In-house accounting administrative assistants earn $38,000-$56,000 annually at base salary, with total employer cost running $48,000-$73,000 after adding the 25-30% benefits and payroll tax burden on top.
Yes; an EA with verified Drake, UltraTax, or Lacerte experience reduces onboarding time from weeks to days and operates with less oversight during tax season, making the 15-25% rate premium nearly always worth it for practices with high January-April volume.
Seasonal engagements run 10-20% above standard rates during peak demand, and re-onboarding costs make year-round retainers more cost-effective for most firms once you account for three or four months of elevated need across primary tax season and extension season.
High-value EA tasks for accounting practices include client document collection, deadline and extension tracking, portal management, engagement letter preparation, client scheduling, and IRS notice coordination, all of which free preparer time for billable work.
Yes, with appropriate training and clear process documentation; offshore EAs with prior accounting firm experience can manage accounting-specific tasks independently, and even general EAs can handle the majority of CPA administrative work after a structured 30-60 day onboarding period.
