Accounting firms and accountants should plan for tax season well in advance to ensure that clients receive accurate and timely tax returns. The entire tax returns process can be difficult and stressful.

Tax preparation and self-assessment tax returns require a thorough knowledge of tax legislation. This is so that there are no risks in the execution of tax processes. During tax season, however, many accountants may not have the time or budget to complete all client deliverables. High workloads can also impact productivity, particularly for small accounting firms and individual accountants. In such circumstances, accountants may choose to outsource tax returns tasks for their clients, including self-assessment tax return returns to specialized service providers.
