What is a C corporation?A C corporation is a corporate structure where the company profits are taxed separately from its owners. In other words, the corporation is legally viewed as an independent, separate entity. This means that the owners are shareholders and the corporation functions outside of their personal finances. A C corporation’s shareholders elect a board of directors and have officers that make business decisions and oversee policies.How C Corporations Are TaxedCorporate Tax: A C corporation pays tax on its profits at a flat 21% federal rate. This is reported on Form 1120.Shareholder Tax (the “Double Tax” part): If the corporation distributes profits to shareholders as dividends, the shareholders then pay tax on those dividends on their personal tax returns.Debunking the Double Taxation MythYes, a C corporation’s profits can be taxed at both the corporate and shareholder level if distributed as dividends, but this doesn’t have to be a deal-breaker. Take these points into consideration:Dividends aren’t mandatory: Corporations can retain profits to fund growth, acquisitions, or R&D, deferring shareholder-level taxes.Tax planning strategies exist: Shareholder salaries, bonuses, and dividends can be structured to minimize overall tax impact.Double taxation mostly affects passive assets: The risk is higher if the corporation holds appreciating assets like patents, marketable securities or real estate. For active businesses, reinvested earnings can outweigh the extra tax cost.Why the C-Corp Can Make SenseFlat Corporate Tax Rate: Since the Tax Cuts and Jobs Act (TCJA), C corporations pay a flat 21% federal income tax rate, which can be lower than the top individual tax rate for high-income business owners.Income Flexibility: Unlike pass-through entities (S corps, LLCs, partnerships, and sole proprietorships), C corporations can retain earnings within the company. This allows for reinvestment and growth without immediately triggering individual-level taxes.Strategic Planning Opportunities: Certain benefits (like more flexible fringe benefits, deductible business expenses, and potential stock-based compensation) can make a C-Corp an attractive option for growing businesses.Did the One Big Beautiful Bill Act (OBBBA) impact C corporation status at all?Yes, the One Big Beautiful Bill Act (OBBBA) introduces several tax changes that can influence whether a C‑corporation structure is advantageous:Bonus Depreciation- The OBBBA permanently reinstates 100% first‑year bonus depreciation for most qualifying property acquired after January 19, 2025. It also introduces an elective full-expensing option for certain U.S. nonresidential property used in manufacturing or production through 2030.Implication for C‑Corps: Companies making significant capital investments can accelerate deductions, lowering taxable income and improving cash flow.Interest Expense Deductions- The OBBBA restores a more favorable calculation for business interest limits by allowing add-backs for depreciation, depletion, and amortization (DDA), effectively using an EBITDA‑style base rather than EBIT.Implication for C‑Corps: Debt-heavy, capital-intensive companies can reduce the tax impact of interest expenses, making the C‑corp structure more tax-efficient.Net Operating Losses (NOLs) & Loss Limitations- The bill does not materially change corporate NOL carryforwards, which can generally offset up to 80% of taxable income. It does, however, permanently limit excess business losses for non‑corporate taxpayers.Implication for C‑Corps: While direct effects are limited, the combination of accelerated deductions and interest limits can influence the timing and utilization of NOLs, making strategic tax planning important.Qualified Small Business Stock- OBBBA enhances the benefits of IRC Sec. 1202 for qualified small business stock acquired after July 4, 2025, increasing the gross-asset threshold from $50 million to $75 million, raising the minimum gain exclusion from $10 million to $15 million, and allowing partial exclusions for stock held three or four years (50% and 75%, respectively), with the full 100% exclusion still available after five years.Implication for C Corps: These changes expand eligibility and provide greater flexibility for founders and investors, reinforcing the long-term tax advantages of holding a business in C-corporation form when pursuing QSBS opportunities.Don’t forget to download our Year End Tax Planning Guides for Businesses and Individuals.
