Tax season shouldn’t feel like controlled chaos every single year. Yet for many CPA and accounting firms, the pattern is familiar:
- Partners pulled into last-minute reviews
- Seniors firefighting instead of coaching
- Staff working nights and weekends
- Projects bunching up in the final weeks before deadlines
The core issue usually isn’t technical tax complexity—it’s capacity and workflow design. When all the work is squeezed through the same onshore team, at the same time of year, bottlenecks are inevitable.
That’s where strategic offshoring comes in. Not as a quick fix or cost-cutting tactic, but as a deliberate way to rebalance workloads between onshore and offshore teams so your firm can handle peak volume without burning people out.
In this article, we’ll look at how to design an onshore–offshore model that actually works in practice – what to offshore, what to keep onshore, and how to orchestrate the two so tax season feels more manageable and predictable.
Why Tax Season Creates Bottlenecks in the First Place
Before reengineering the model, it helps to name the problem. Most tax-season bottlenecks come from a mix of:
- Front-loaded client coordination
Chasing organizers, source documents, and signatures often lands on your most expensive people. That delays prep work and pushes everything closer to deadlines. - Overloaded review layers
When partners and managers are the only ones reviewing returns, every file waits in line for the same small group. As volume spikes, so do delays. - Uneven work allocation
Simple and complex returns are treated the same from a resourcing standpoint. Staff get overwhelmed with low-complexity work that could easily be handled elsewhere. - Limited hours in the day
No matter how efficient your processes are, your local team can only work so many hours in a week. During peak weeks, volume simply exceeds available capacity.
Strategic offshoring is about redistributing that workload intelligently, so your onshore team can focus on what must be handled locally while offshore colleagues carry more of the repeatable, process-driven work.
Offshoring as a Strategy, Not Just a Cost Play
Many firms first explore offshoring to reduce costs. But the real strategic benefits show up in areas like:
- Capacity smoothing: Use offshore teams to absorb peak-season spikes instead of hiring full-time staff you can’t fully utilize year-round.
- Higher-value use of local staff: Free up partners and seniors to focus on complex work, advisory conversations, and client relationships—not data entry and first-pass prep.
- Time-zone leverage: Offshore teams in different time zones can push work forward overnight, so your onshore team starts the day with returns ready for review.
- Scalability: Once your onshore–offshore workflow is defined, adding capacity becomes much easier—new “seats” can plug into proven processes.
The key is to design offshoring into your operating model, rather than handing off random tasks at the last minute.
What Stays Onshore vs. What Moves Offshore
A successful offshoring strategy starts with a clear division of responsibilities. Think in terms of work types, not job titles.
Work That Typically Stays Onshore
These activities are closer to the client, require nuanced judgment, or carry signature responsibility:
- Building and maintaining client relationships
- Advisory discussions and planning conversations
- Reviewing complex or high-risk returns
- Final technical review and sign-off
- Handling sensitive or unusual tax positions
- In-person or high-touch client meetings
Work That’s Ideal for Offshore Teams
Offshore staff can handle a surprisingly large portion of tax-season workload when processes are defined clearly. Examples include:
- Organizing client documents and mapping them to workpapers
- Data entry into tax software and workpaper systems
- Preparing basic and moderately complex returns based on clear guidelines
- Drafting pro forma returns
- Preparing and tracking extensions
- Running diagnostics and clearing standard software warnings
- Compiling e-file packages and documentation for review
- Updating status trackers and workflows in your practice management system
The more standardized and repeatable a task is, the better it fits offshore.
Operating Models: Outsourcing vs. Dedicated “Tax Seats”
Not all offshoring models are the same. Broadly, firms tend to choose among three options:
- Project-based outsourcing
- You send work to a provider on a project-by-project basis.
- Pros: Flexible, easy to test.
- Cons: Less control, variable turnaround, harder to embed in your internal processes.
- Hybrid in-house + offshore team
- Some tasks are handled by in-house staff, others by an offshore provider on a recurring basis.
- Pros: Balance of control and flexibility.
- Cons: Requires deliberate process design and ongoing coordination.
- Dedicated “seat” model
- You effectively add dedicated offshore team members, integrated into your workflows and tech stack.
- Pros: Consistency, relationship-based collaboration, better quality over time, easier planning.
- Cons: Requires commitment and upfront onboarding effort.
Many firms find the seat model particularly effective for tax. For example, a dedicated “tax seat” can work in your tax software and practice management tools, follow your templates and procedures, and report to your managers – just from a different geography.
As one option in this space, Finsmart Accounting’s CPA USA Tax Seat is designed to plug into existing CPA firm workflows with dedicated offshore professionals during tax season and throughout the year. You can treat this kind of seat as an extension of your team, rather than a separate vendor workflow.
Practical Strategies to Distribute Workload Onshore and Offshore
Once you’ve chosen your operating model, the next step is designing how work flows between teams.
1. Tier Your Returns by Complexity
Instead of treating every return the same, classify work into tiers and assign ownership accordingly:
- Tier 1 – Simple / Standardized returns
- Offshore team prepares from start to finish based on clear checklists.
- Onshore team performs a light review and sign-off.
- Tier 2 – Moderately complex returns
- Offshore team handles data collation, workpapers, and first-pass prep.
- Onshore seniors/managers handle technical adjustments and final review.
- Tier 3 – Complex / High-risk returns
- Onshore team leads the prep and review.
- Offshore team supports with data gathering, schedules, and documentation.
This helps ensure that offshore capacity is maximized without compromising quality or risk management.
2. Use Wave Planning for Tax Season
Instead of letting work pile up randomly, plan capacity in waves:
- Wave 1: Early-filers and simple returns – heavy offshore involvement.
- Wave 2: Core client base with moderate complexity – balanced onshore/offshore.
- Wave 3: Complex, high-fee clients and stragglers – primarily onshore with offshore support.
Mapping anticipated volume to these waves allows you to align offshore staffing with expected peaks.
3. Leverage Time Zones for Overnight Progress
If your offshore team is in a different time zone, design workflows such as:
- Onshore managers assign work and record review notes at the end of their day.
- Offshore team picks up overnight, clears notes, and advances the file.
- Onshore team starts the next day with updated files ready for final review or client communication.
This “follow-the-sun” model can significantly reduce turnaround times and smooth daily workload.
4. Standardize With SOPs, Templates, and Checklists
Offshoring works best when ambiguity is minimized. Invest early in:
- Standard operating procedures (SOPs) for each type of return and task
- Workpaper templates and naming conventions
- Checklists for data requirements, quality checks, and common edge cases
- Clear communication protocols (who to ask, how to escalate questions, expected response times)
The more clearly you document your way of working, the faster offshore team members ramp up and the less time managers spend answering repeat questions.
Quality, Security, and Governance
A strategic offshoring program must protect your firm’s reputation, client trust, and compliance posture.
Quality Control
- Defined review layers: Decide what percentage of offshore-prepared returns are reviewed by seniors vs managers vs partners.
- Rework tracking: Measure rework rates and error types so processes and training can be improved.
- Regular calibration: Schedule periodic review sessions between onshore reviewers and offshore preparers to discuss recurring issues and share feedback.
Data Security & Compliance
Work only with partners who:
- Have robust data security frameworks (e.g. secure infrastructure)
- Use secure file transfer and remote access to your systems
- Have strong confidentiality agreements and background checks in place
- Respect regulatory requirements around data residency and privacy
Communication and Culture
Quality doesn’t come from checklists alone. It comes from consistent collaboration:
- Hold regular check-ins between onshore managers and offshore team leads
- Encourage offshore staff to ask questions rather than guess
- Share context about clients – not just technical instructions – where relevant
The more your offshore team understands your firm’s expectations and culture, the more they’ll behave like an extension of your own staff.
Implementation Roadmap: How to Get Started
If your firm is considering offshoring ahead of next tax season, here’s a practical starting path:
- Clarify your goals
What problem are you solving first – turnaround times, review bottlenecks, staff burnout, margin pressure, or all of the above? - Map your current tax workflow
From client data collection through e-filing and billing, document who does what, where delays occur, and where work piles up. - Identify a pilot scope
Choose a specific set of returns (e.g., simple 1040s, certain business entity returns, or a defined client segment) to start with offshore support. - Select your offshoring model and partner
Decide between project-based support and a dedicated seat model. Evaluate partners on experience with US tax, security, communication, and ability to work in your tech stack. - Set up processes and training
Build SOPs, templates, and checklists; set access to your systems; walk offshore team members through sample files. - Run a structured pilot
Track KPIs like turnaround time, rework, reviewer hours, and client impact. Gather feedback from both onshore and offshore teams. - Refine and scale
Use pilot learnings to tighten processes, adjust what work is offshored, and gradually expand the scope and number of seats.
Bringing It All Together
Balancing workload during tax season isn’t just about “working harder” or hiring more locally. It’s about redesigning how work flows through your firm – so the right people, in the right locations, handle the right tasks at the right time.
Strategic offshoring, especially through a dedicated tax seat model, can help you:
- Smooth out tax-season spikes
- Protect your team from burnout
- Improve turnaround times and client experience
- Free up partners and seniors to focus on higher-value work
If your firm is exploring this direction, you might look at dedicated offshore options like Finsmart Accounting’s CPA USA Tax Seat as one way to add scalable capacity that behaves like part of your own team.
The sooner you design your onshore–offshore strategy, the more your next tax season will feel planned – rather than survived
