Is Switching Your Business from a C to an S Corporation a Good Idea?

Selecting the appropriate business entity is crucial due to its significant tax implications. The most prevalent business structures include sole proprietorships, partnerships, limited liability companies (LLCs), C corporations, and S corporations.
In some instances, a business may opt to transition from one entity type to another. While S corporations can offer considerable tax benefits compared to C corporations, there are several potentially costly tax issues that must be evaluated before deciding to convert from a C corporation to an S corporation.
Here are four critical considerations:
1. LIFO Inventories: C corporations utilizing the last-in, first-out (LIFO) inventory method must pay tax on the benefits derived from LIFO when converting to S corporations. This tax can be distributed over four years. It is essential to compare this cost with the potential tax savings from the S corporation status.
2. Built-in Gains Tax: Generally, S corporations are not subject to tax. However, those that were formerly C corporations are taxed on built-in gains (such as appreciated property) present when the S election becomes effective, provided these gains are recognized within five years post-conversion. Despite being typically unfavorable, there are scenarios where electing S corporation status can still result in better overall tax outcomes.
3. Passive Income: S corporations that were previously C corporations face a special tax if their passive investment income (including dividends, interest, rents, royalties, and stock sale gains) exceeds 25% of their gross receipts and they carry over accumulated earnings and profits from their C corporation years. If this tax is due for three consecutive years, the S corporation status will be terminated. This can be avoided by distributing the accumulated earnings and profits, taxable to shareholders, or by limiting passive income.
4. Unused Losses: Unused net operating losses from a C corporation cannot be utilized to offset income of an S corporation and cannot be passed through to shareholders. If these losses cannot be carried back to an earlier C corporation year, it is necessary to consider the cost of forfeiting these losses against the anticipated tax savings from switching to S corporation status.
Additional Considerations
These points are merely a few factors to consider when transitioning from a C corporation to an S corporation. For instance, shareholder-employees of S corporations do not qualify for all tax-free fringe benefits available to C corporations. Additionally, there may be implications for shareholders with outstanding loans from their qualified plans. It is vital to evaluate these aspects to fully understand the consequences of converting from C to S status.
