Every year, the IRS reports that more than 160 million individual income tax returns are filed, and most of them are the standard 1040 returns. For every CPA firm, this turns into a busy season of long shifts, high staffing costs, and the constant worry of missed deadlines.

Many businesses now outsource 1040 preparation to handle the volume. When you delegate routine returns to a trusted partner, your team gains time to focus on higher-value work like advisory, tax planning, and building client relationships.

Outsourcing only works if you pick the right partner. The wrong choice can introduce problems such as weak data security or mistakes in returns.

This guide shows you the benefits, the risks, and a due diligence checklist so you can select the right outsourcing partner and protect your firm’s profitability.

The Benefits and Considerations of Outsourcing

Outsourcing1040 preparation is no longer just for large firms. Even small and mid-sized CPA practices are turning to it to handle seasonal pressure and improve efficiency. While the benefits are clear, there are also practical considerations that firms must keep in mind before making the move.

The Case for Outsourcing: Benefits of Outsourcing 1040

Outsourcing 1040 preparation helps CPA firms handle more returns without sacrificing quality. The most direct benefits include:

• Relief during busy season – Every CPA knows the stress of January through April. Outsourcing helps manage the workload so partners and staff can concentrate on higher-value client work instead of getting buried in data entry.
• Better use of resources – Routine returns can be handled externally, while your in-house team focuses on planning, advisory, and client relationships that drive growth.
• Scalable support – Outsourcing can be used only when needed. Some firms outsource just 20–30% of returns during peak season rather than committing to new permanent staff.
• Bridging staffing shortages – With talent harder to find in the accounting profession, outsourcing fills the gap without the cost of recruitment and training.
• Profitability boost – By reducing time spent on basic prep work, firms often see stronger margins and more capacity for billable advisory services.

Key Concerns Firms Must Weigh Before Outsourcing

Data Security

• Client tax records contain highly sensitive information—Social Security numbers, income data, and banking details. Before outsourcing, firms must ensure that their partners
• Use secure portals and encrypted data transmission.
• Follow strict confidentiality and compliance standards (e.g., IRS, GDPR).
• Have clear policies for data access, storage, and retention.

Accuracy and Quality Control

• Errors in tax returns can damage client trust and expose the firm to liability. Firms should evaluate
• The outsourcing provider’s accuracy assurance methods.
• Whether all returns undergo a secondary review before submission.
• The qualifications and training of preparers working on client files.

Communication and Workflow

• Outsourcing often involves cross-border collaboration and time zone differences. To prevent bottlenecks or misunderstandings
• Establish clear communication protocols and escalation paths.
• Use standardized collaboration tools and workflow management systems.
• Define turnaround times and responsibilities in writing.

Consistency in Client Experience

• Even when work is performed externally, the client’s experience should feel seamless. Maintain consistency by
• Align outsourced deliverables with your firm’s quality standards and tone.
• Conducting periodic reviews to ensure outputs reflect your firm’s brand and service ethos.
• Providing clear feedback loops between in-house and outsourced teams.

The Due Diligence Checklist for Selecting an Outsourcing Partner

1. What Is Their Data Security Protocol?

Tax preparation involves highly sensitive client information such as Social Security numbers (SSNs), bank details, and income records. A trust worthy outsourcing partner should maintain robust data protection measures.

Ask about:

• Encryption standards and cybersecurity certifications.
• Secure portals or encrypted document transfer systems.
• Compliance with IRS, FTC, and state-level data protection regulations.
• Internal access controls and employee confidentiality policies.

Why it matters:

Firms that skip this step risk data breaches or compliance violations. Strong tax data security isn’t just a legal requirement—it’s the first line of defense protecting both your clients and your firm’s reputation.

2. How Do They Ensure Quality and Accuracy?

Accuracy is non-negotiable in tax preparation. Before partnering, understand how the provider maintains high standards of precision and accountability.

Ask about:

• Multi-tier review systems (e.g., a second-level review for complex returns).
• Staff training and qualifications—are CPAs or EAs involved?
• Specialization areas, such as investment, business, or rental income returns.
• Procedures for error tracking and correction.

Why it matters:
Firms with clear processes for accuracy assurance consistently deliver reliable results, reducing the risk of IRS audits and client dissatisfaction. Confirming this early helps prevent costly rework and delays.

3. What Is Their Workflow and Communication Process?

Smooth collaboration depends on transparent, consistent communication. Misunderstandings or missed updates can lead to costly errors and deadline crunches.

Ask about:

• File-sharing methods and project-tracking tools (e.g., portals, dashboards, or project management software).
• Communication channels—email, Slack, dedicated account managers, etc.
• Typical response times and escalation procedures.
• Time-zone overlaps and availability during peak tax season.

Why it matters:
A partner with a clear and efficient workflow keeps your internal team organized and helps ensure no deadlines are missed. Firms that define expectations upfront experience f4ewer disruptions during busy periods.

4. What Is Their Pricing Model?

Pricing structures vary widely. Understanding the model and inclusions ensures that the partnership is both cost-effective and transparent.

Ask about:

• Whether pricing is per return, hourly, or seasonal.
• What’s included—e-filing, reviews, amendments, or client communications.
• Additional fees for rush work or revisions.
• How do their rates compare to your firm’s internal cost per return?

Why it matters:
Transparent discussions around the cost of outsourcing prevent surprises and protect profitability. The right partner should deliver measurable value—enhancing efficiency without eroding your margins.

5. Are they compatible with your existing software?

Software compatibility is a very important aspect when finalizing the partner for 1040 preparation. If your firm uses Lacerte, UltraTax, or Pro Series, make sure the outsourcing partner can work with these systems.

Setup should be easy to avoid duplicate entry or errors. Asking about tax software compatibility avoids frustrating technical issues and keeps your workflow efficient.
