Introduction
When it comes to handling 1120-S filings, CPA firms across the U.S. often face a key question. Should they go with an onshore team or explore offshore options? Each path has its benefits and trade-offs, particularly in terms of cost, quality, and data security. Today, 1120S outsourcing services are becoming more common. So, it is a good idea to spend a few minutes understanding the pros and cons of both models. This can help your firm make a more intelligent, more secure choice.
Let us put it straight—choosing between onshore and offshore outsourcing for your 1120-S tax preparation depends upon your priorities. However, certain key factors can influence your decision and lead you to select either option. In this blog, we will attempt to understand the pros and cons of each method and also discuss whether these approaches are secure enough to be considered.

Considering Onshore Outsourcing?
If you prefer easy communication and working with someone in the same time zone, an onshore 1120S outsourcing service might be a good fit. It’s often more expensive, but it provides better control, enhanced data security, and greater comfort when handling complex tax cases.
Pros of Onshore Outsourcing:
Choosing an onshore provider for your 1120-S tax filing can generally mean better communication and easier collaboration. There may be fewer issues, and you can benefit from a potentially smoother partnership with the provider. Yet another advantage is that they are more likely to be well-versed in the tax laws specifically concerned with 1120-S filings and the relevant regulations that apply to your business. As a CPA firm owner, you could have more direct control. Also, you can ensure better data security and compliance with local laws. Finally, your onshore provider may allow for easier face-to-face meetings and collaboration. This approach may prove to be more effective for complex issues related to 1120-S tax filings.
Cons of Onshore Outsourcing:
While your onshore provider may provide you with a par excellence service, this may incur a phenomenally higher cost. Onshore outsourcing typically incurs higher labor costs compared to offshore options. Additionally, 1120-S tax preparation is a specialized task, so the talent pool for such a dedicated job might be smaller in your local area.
Considering Offshore Outsourcing?
If you want to save money and still get quality work done, offshore 1120S outsourcing services can be a great choice. You gain access to skilled teams at a lower cost, but you’ll need to plan for time zone differences, potential communication issues, and robust data security measures.
Pros of Offshore Outsourcing:
Offshore outsourcing offers significant cost savings due to lower labor costs in other countries. Additionally, you get access to a broader range of professionals with specialized skills and experience. Additionally, offshore teams can offer 24/7 support, despite time zone differences.
Cons Of Offshore Outsourcing:
However, communication challenges can hinder offshore support. Cultural differences, language barriers, and time zone discrepancies can significantly contribute to communication challenges and delays. Additionally, this process can increase the risk of data breaches, which may require more stringent security measures. There could be potential compliance issues, as ensuring compliance with local tax laws and regulations can be more complex. Ultimately, it may be more challenging to maintain quality control when collaborating with an offshore team.
Comparing Security: Onshore vs. Offshore
In terms of data security, onshore outsourcing generally feels more secure due to local laws and familiar compliance standards. Offshore outsourcing, while often perceived as riskier, can also be safe if the provider adheres to strong data protection practices, encryption, and global standards. Whether you choose onshore or offshore, the real difference lies in how seriously your 1120S outsourcing service provider handles security and not just where they’re located.
