Why CPA Firms Are Outsourcing More Accounting Work in 2026

The way CPA firms manage their teams is changing. Workloads go up and down throughout the year. Tax season can bring a huge increase in tax preparation and bookkeeping work, while the rest of the year still requires ongoing accounting, reconciliations, financial reporting, and client support. At the same time, hiring and retaining experienced accounting professionals can be challenging.

This is one reason more CPA firms are looking at outsourcing as a way to add capacity without constantly expanding their internal team.

Managing Busy Season Without Overloading the Team

Tax season is probably the biggest example. A firm may have a strong team, but when hundreds of additional returns and client requests arrive at the same time, even experienced professionals can become stretched. Instead of having senior staff spend most of their time on routine preparation work, firms can use additional support for tasks such as:

Tax return preparation
Workpaper preparation
Bookkeeping
Bank and credit card reconciliations
Supporting schedules
Data entry and organization
Financial statement preparation

This gives the firm's internal team more time for review, client communication, complex tax matters, and other responsibilities that require their experience.

Hiring Is not Always the Answer

Hiring more employees sounds like the obvious solution when workload increases.

But permanent hiring comes with recruitment, onboarding, training, payroll, benefits, and management responsibilities. More importantly, the firm's workload may not remain at the same level throughout the year. Outsourcing gives firms another option. Instead of building the entire team around peak workload, a firm can add outside capacity when it makes sense for its workflow.

More Time for Higher-Value Work

CPA firms are also spending more time on services beyond traditional compliance. Tax planning, advisory services, financial analysis, and client consulting all require time and attention.

Routine accounting and preparation work still needs to be done, but it doesn't always need to be handled personally by the firm's most senior professionals.

A practical approach is to divide responsibilities based on the type of work:

CPA Firm

Client relationships
Review
Professional judgment
Complex matters
Final decisions

Outsourced Team

Bookkeeping
Reconciliations
Tax preparation support
Workpapers
Supporting schedules
Accounting tasks

The exact division depends on the firm's processes and review procedures.

Outsourcing Is not Just for Tax Season

One of the biggest advantages of having an external accounting team is that support doesn't have to stop when tax season ends.

During the off-season, firms still have monthly bookkeeping, reconciliations, financial reporting, cleanup work, and year-end preparation. Keeping these tasks moving throughout the year can also make the next tax season easier.

Instead of starting each tax season with months of unfinished bookkeeping, firms can work toward having cleaner and more up-to-date client records.

Technology Makes Remote Collaboration Easier

Cloud accounting platforms and digital workflow tools have made it much easier for CPA firms to work with teams outside their office.

Documents can be shared electronically, tasks can be assigned remotely, and completed work can move through the firm's existing review process.

This allows firms to build a support structure without requiring every person involved in the work to sit in the same office.

How Disam Supports CPA Firms

At Disam, we work with CPA and accounting firms as an extension of their existing team.

Our support includes:

The goal isn't simply to outsource as much work as possible.

It's to help firms decide where additional capacity makes sense and provide support that fits into their existing workflow.

A firm may need significant tax preparation support during busy season and more bookkeeping or accounting support during the rest of the year.

The needs change. The support model can change with them.

The Bigger Picture

For CPA firms, outsourcing is increasingly becoming a question of capacity and workflow rather than simply cost.

The important question is:

Which work should stay with the internal team, and which work can be supported by an experienced external team?

When that division is clearly defined, outsourcing can become another tool for managing workload, supporting growth, and giving CPA professionals more time to focus on their clients.
