Key Topics
1. Corporate Capital Gains Tax Rate
Unlike individual taxpayers who enjoy preferential tax rates of 0%, 15%, or 20% on long-term capital gains, C-Corporations receive no preferential tax rate on capital gains. All corporate capital gains — whether short-term or long-term — are taxed at the standard federal corporate income tax rate of 21% under IRC Section 11.
2. IRC Section 1231 Business Assets
Property used in a trade or business held for more than one year is governed by Section 1231. Net Section 1231 gains are treated as long-term capital gains (subject to 5-year lookback recapture rules), while net Section 1231 losses are treated as ordinary losses that fully offset operating revenue.
3. Corporate Capital Loss Limitations
Corporations cannot deduct capital losses against ordinary business income. Capital losses can only offset capital gains. Unused corporate capital losses must be carried back 3 taxable years and forward up to 5 taxable years, reported on Form 1120 Schedule D.
Step-by-Step Guide
Segregate Business vs Investment Assets
Distinguish between ordinary income property, Section 1231 business property, and pure capital investment assets.
Calculate Net Capital Position
Sum corporate capital gains and capital losses. Determine whether net capital gains exist for the taxable year.
Apply 21% Corporate Tax
Include net capital gains in corporate taxable income subject to the standard flat 21% corporate income tax.
Manage Capital Loss Carrybacks and Carryforwards
If capital losses exceed capital gains, apply the 3-year carryback or 5-year carryforward rules on Form 1120 Schedule D.
Tips & Best Practices
- Timing of capital asset sales across tax years can prevent stranded capital losses from expiring after 5 years.
- Section 1245 and Section 1250 depreciation recapture takes priority over Section 1231 capital gains treatment on depreciable property.
- Consult corporate tax counsel when structuring asset sales vs stock purchases in M&A transactions.
