Crypto Tax Reporting for Businesses US 2026 – Corporate and LLC Guide

Tesla did it. MicroStrategy built an entire treasury strategy around it. Now smaller businesses and LLCs are asking the same question: how does any of this actually get taxed at the company level? Business crypto works very differently from personal holdings. Here's how the IRS sees it.

How Business Crypto Is Taxed Differently

Here's the big one right away: C-Corporations pay a flat 21% corporate tax rate on all gains. No preferential long-term capital gains rate like individuals get. S-Corps and LLCs pass everything through to the owners, who then pay at their individual rates — but the character of the income flows through too.

Bitcoin on the Corporate Balance Sheet

• GAAP (old rule): Intangible asset — impairment writedowns when price falls, but gains only recognized on actual sale
• FASB 2025 rule: Companies can now elect fair value accounting — recognize gains and losses each reporting period even without selling
• Tax (regardless of accounting method): Still only taxable on actual sale or disposal

Accepting Crypto Payments

When your business accepts crypto for goods or services, the FMV on the date received equals ordinary business income — recognized immediately, whether you hold or sell the crypto. That FMV becomes your cost basis in the crypto. When you eventually sell it, you calculate gain or loss from there.

Paying Employees and Contractors

• Employees: FMV on the pay date = wages, subject to withholding and FICA; goes on the W-2
• Contractors: FMV on the pay date = self-employment income for them; issue a 1099-NEC if over $600
• The business deducts it like any other compensation expense

Deductible Business Crypto Expenses

• Transaction fees with a clear business purpose
• Crypto tax software subscriptions
• Custody and security infrastructure costs
• Mining equipment — Section 179 expensing or depreciation
• Accounting and legal fees related to crypto operations

Form 8300: Large Crypto Transactions

If your business receives more than $10,000 in crypto — or cash — in a single transaction or related transactions, you must file Form 8300 within 15 days. The Infrastructure Investment and Jobs Act of 2021 expanded this requirement to explicitly include crypto. This catches a lot of businesses off guard. Don't let it catch you.
