If you pay employees in Bitcoin, Ethereum, or any cryptocurrency, the IRS treats the payment as wages subject to federal income tax withholding, Social Security tax, and Medicare tax. The fair market value of the crypto on the date of payment is the wage amount. There are no exceptions.

Withholding Requirements

Notice 2014-21 Q&A 11 states that wages paid in virtual currency are subject to federal income tax withholding, FICA, and FUTA. The employer must calculate the fair market value of the cryptocurrency on the payment date, withhold the appropriate taxes (which must be remitted in U.S. dollars), and report the wages on Form W-2. The withholding obligation cannot be satisfied in cryptocurrency — it must be cash.

Independent Contractors

Payments to independent contractors in cryptocurrency exceeding $600 must be reported on Form 1099-NEC based on the fair market value at the time of payment. The contractor is responsible for self-employment tax on the income. The payer does not withhold for contractors but must still file the information return.

Employer Payroll Tax Exposure

Employers who pay workers in crypto but fail to withhold and remit payroll taxes face trust fund recovery penalties under §6672. This penalty equals 100% of the unpaid trust fund taxes (the employee's share of income tax and FICA withholding) and is assessed personally against responsible individuals — not just the company. Crypto payroll that bypasses proper withholding creates severe personal liability for business owners.

Valuation Volatility

Crypto prices can move significantly within a single day. The fair market value at the time of payment determines the wage amount. If you pay an employee 1 BTC when Bitcoin is at $50,000, the W-2 reports $50,000 in wages regardless of what Bitcoin does afterward. This creates planning challenges for both employer and employee.
