Business Diversification: S Status Conversion

Business diversification will always need to include some accounting for tax. Truly diversified companies will always consider the tax implications of their M&A activity and overall business strategy. C-corporations seeking a way to shelter more from the government, avoid taxes and further diversify should take a hard look at an S Status Conversion. In short, an S Status Conversion will allow the company to distribute earnings to small business owners free of the double-tax imposed on C Corporations.

Why C Corporations Consider S Status Conversion

The core appeal of converting from a C corporation to an S corporation lies in pass-through taxation. Under a C corporation structure, profits are taxed at the corporate level and again when distributed to shareholders as dividends — the classic double-taxation problem. An S corporation eliminates that second layer by passing income, losses, deductions, and credits directly to shareholders, who report them on their individual returns.

For closely-held businesses with a small group of owners, this can represent a meaningful improvement in after-tax cash flow. When planning a potential ownership transition, understanding the entity structure is foundational to sell-side preparation — buyers and their advisors will scrutinize entity type, accumulated earnings, and tax history carefully.

Two Major Downsides to Converting to S Corp Status

There are two major downsides to converting to S Corp status:

1. The company will lose the low tax rates imposed on income accumulations of up to $75K annually for C corporations. 2. The newly converted S Corp will also lose the ability to offer tax-preferred employee benefits to company employees and shareholders.

In many instances, however, these downsides are not large enough for the profitable C Corp who may need to properly diversify.

Offsets and Nuances

There are a few offsets to the downsides.

1. There is a 5% corporate tax “bubble” which occurs once businesses hit the $100K mark. In effect, this creates a standard 34% flat tax on all corporate earnings up to $10 million. 2. Silent “golfer” owners will find little upside to tax-preferred employee benefits. At least, the benefits will generally not be enough to offset the diversification benefits of converting to an S Corp.

While there are a number of nuances and a few more considerations to take into effect when converting to an S Corp (like having fewer than 100 shareholders, one class of voting stock, etc.), the analysis should be part of a broader capital structure review whenever a business owner is considering a liquidity event or a recapitalization. Teams using a recapitalization preparation workflow will typically address entity elections early in that process.

Conversion Traps to Watch Carefully

There are a number of other conversion traps which need to be considered when swapping out your C Corp for an S Corp. Here are a few to consider.

Post-conversion S Corp distributions in excess of S Corp earnings triggers a shareholder dividend tax to the extent of the C earnings and profits. This could put a threshold cap on distributions to ensure they do not exceed S Corp earnings. In the event of profitable C Corps which convert, this could prove problematic, especially if the C Corp had a great deal of cash or retained earnings on hand at the time of conversion.

Accumulated C Corp earnings can also trigger a section 1375 tax trap wherein investment income on an S Corp is taxed at the highest corporate rate (35% as of today) in the event that net passive income (interest, dividends, rents, royalties, etc.) exceeds 25% of gross receipts. In this event, it is wise to monitor passive income from the S Corp to ensure it does not exceed the 25% threshold of gross receipts.

Finally, an S Corp can be subject to the built-in-gain (“BIG”) tax trap (or section 1374). This tax kicks in when the newly converted S Corp attempts to sell assets owned by the C Corp at the time of the conversion within 10 years of the conversion date. The BIG tax is in addition to any tax triggered at the S-level on any gain from the asset sale and is imposed at the maximum corporate rate (35% as of today) on the lesser of: a. Built-in-gain at the time of conversion, or b. The gain recognized on the sale of said assets.

In any event, careful consideration should be given to divesting assets after converting from a C Corp to an S Corp.

Strategic Timing and the Long View

Conversion itself should be considered carefully as a strategy congruent with the business’s short and long term goals and vision, including any potential future merger activity. Owners who are weighing conversion as part of a broader exit-planning effort should map out the 10-year BIG window against their projected transaction timeline — converting too close to a planned asset sale can negate the tax benefits of conversion entirely.

Practitioners who work through a structured transaction preparation process will often surface entity-structure questions early, because the structure at the time of sale directly affects net proceeds to the seller.

Key Eligibility Requirements for S Corp Status

• The corporation must be a domestic entity.
• Shareholders must be U.S. citizens or resident aliens (no non-resident alien shareholders).
• The corporation may not have more than 100 shareholders.
• Only one class of stock is permitted (though differences in voting rights are allowed).
• Certain entity types — financial institutions, insurance companies, domestic international sales corporations — are ineligible.

These eligibility rules can create complications for businesses that have grown their investor base, issued preferred equity, or brought on institutional investors. A careful cap-table review should precede any conversion filing.

Frequently Asked Questions

Can a C corporation with multiple classes of stock convert to S status?

No. S corporation status requires a single class of stock. Before conversion, companies with preferred shares or other equity classes must restructure their capitalization to a single class. This restructuring itself can have tax consequences and should be planned carefully with qualified tax counsel.

What happens to a C corporation’s net operating loss carryforwards upon S election?

Net operating losses generated under C corporation status generally cannot be used to offset S corporation income. Those losses remain available only if the corporation ever reverts to C status. This is an often-overlooked cost of conversion for companies that have historically operated at a loss.

How does the built-in-gains tax affect asset sale planning after conversion?

The BIG tax applies to assets that had unrealized appreciation at the time of conversion if those assets are sold within the recognition period (historically 10 years, subject to legislative changes). Sellers should model the after-tax proceeds of an asset sale versus a stock sale under both C and S structures before committing to a conversion strategy.

Is S status conversion reversible?

Yes, but with significant restrictions. Once an S election is revoked or terminated, the corporation generally cannot re-elect S status for five years. Strategic decisions about conversion should therefore account for the long-term operating and exit scenario, not just the near-term tax benefit.
