What is Cryptocurrency mining income?

Cryptocurrency mining income represents ordinary income earned by validating blockchain transactions and adding new blocks to distributed ledgers through computational work or proof-of-stake validation. Miners receive newly created cryptocurrency plus transaction fees as compensation, with the fair market value at receipt establishing both taxable income for the 2025 tax year and cost basis for future disposal calculations when selling, trading, or spending the mined assets. Mining conducted as a trade or business requires reporting on Schedule C, including deductible expenses such as equipment purchases, electricity costs, internet service, facility expenses, and depreciation. In contrast, casual mining appears on Schedule 1 as other income without offsetting business expense deductions. Self-employment tax obligations equal to 15.3% apply to business-level mining operations beyond regular income tax rates, potentially creating combined tax burdens exceeding 50% for successful miners in upper tax brackets. Depreciation and amortization deductions for mining hardware enable cost recovery over five-year periods under Modified Accelerated Cost Recovery System schedules, while Home office deductions may apply to residential mining operations that meet exclusive-use requirements and regular business-use standards. The IRS treats mining income identically to other forms of compensation for services, requiring immediate recognition of ordinary income regardless of whether miners immediately sell the cryptocurrency or hold it for long-term appreciation and preferential capital gains treatment.
