If you are a CPA firm planning to outsource your tax return services, then read further! The tax return outsourcing services process for accounting and CPA firms is a strategic process. It begins with client documentation collection and ends with filing and post-submission support.
This constitutes a workflow that addresses peak season demands, increases efficiency, and provides access to specialized expertise, which many firms follow in the case of outsourced processes. Robust security measures and technology characterize this outsourcing process, so that accuracy is maintained and sensitive client data is protected.
In this blog, we will explore the journey of an outsourced tax return services process, from document collection to filing and post-filing support.
The Tax Return Outsourcing Journey
The very first step in the tax return outsourcing services journey begins with client onboarding and document collection. Here, the in-house team collects the financial documents and information from their clients.
Next, they transfer the data to the outsourcing partner via secure, encrypted channels or cloud-based portals. Various types of documents are collected as part of standard requirements, which include tax organizers, prior-year tax returns, financial statements, payroll records, and investment statements.
Now, the accounting firm defines its needs and communicates key objectives to the outsourcing provider as part of the initial engagement. This sets the scope of the engagement and establishes the foundation for a successful partnership.
Data Processing and Preparation
Upon receiving the document, the outsourcing provider’s tax professionals begin data entry and preparation. As part of the data entry process, all financial data is meticulously entered into the accounting firm’s preferred tax software, such as Drake, ProConnect, Lacerte or UltraTax CS. Next, the process moves forward to analysis and optimization, where the outsourcing team analyses the information. Here, the team identifies potential tax savings, deductions, and credits. Also, they prepare the tax return for maximum benefit and accuracy.
Quality Review and Audit
Now, before the return is submitted, reviewers undertake a rigorous, multi-level review process to minimize errors and ensure compliance. At the internal review stage, the outsourcing team performs an initial quality check to verify if all data is entered correctly. All computations are checked for accuracy, too. Next, the tax return outsourcing services team sends back the completed return to the in-house accounting firm. Here, the firm reviews it finally and sends it to the client for their approval. In this way, the firm retains control over the client relationship.
Approval and Filing
When the client and the firm’s in-house team provide final approval, the return is ready for submission. At this stage, the client reviews and signs off on the final tax return before filing. Now, the outsourcing partner files the return electronically with the appropriate tax authorities. The partner ensures that the process meets deadlines at all stages.
Post-Filing Support
If you assumed that approval and filing were the last step, there’s one more step that niche outsourcing firms like KMK Associates offer. Post-filing support often extends beyond the tax deadline so that any follow-up needs can be addressed. As part of audit support, the outsourcing firm assists by helping to manage documentation and communication with tax authorities in the event of a tax audit. Also, some providers offer continuous monitoring, which allows the client to stay compliant with the ever-changing tax regulations.
Why Outsource Accounting
Outsourcing during tax season gives accounting firms the flexibility to manage heavy workloads without hiring and training more staff. It provides access to skilled tax experts, reduces overhead costs, and ensures faster turnaround times with the support of global teams. Reputable providers also use strong security systems to keep client data safe. While there can be challenges like data safety, communication gaps, or quality issues, these can be managed by choosing a trusted partner, starting with a small project, and maintaining clear communication and review processes.
