Cryptocurrency and Digital Asset Tax Rules for Small Businesses

The IRS classifies cryptocurrency and other digital assets as “property” under Notice 2014-21, not as currency. This means every disposition of crypto (sale, exchange, payment for goods or services, or conversion to another cryptocurrency) is a taxable event that may generate a capital gain or loss. For businesses, the implications are broader: accepting crypto as payment creates ordinary income at the FMV on the date of receipt, mining and staking rewards are ordinary income when received, and paying employees or contractors in crypto requires the same withholding and reporting as cash compensation. Beginning with the 2025 tax year, centralized exchanges and brokers are required to report digital asset transactions on Form 1099-DA, bringing crypto reporting closer to the existing 1099-B framework for stocks and securities.

How do crypto transactions affect a small business?

How does the IRS track cryptocurrency transactions?

Starting in 2026, centralized cryptocurrency exchanges are required to report transactions on Form 1099-DA, similar to how brokerages report stock trades on Form 1099-B. The IRS also uses blockchain analytics firms (Chainalysis, CipherTrace) to trace on-chain transactions and match them to known wallet addresses. John Doe summonses issued to major exchanges (Coinbase in 2016, Kraken in 2021, Circle in 2023) have already provided the IRS with account-holder data for millions of users. Every federal income tax return now includes a question on the first page asking whether you received, sold, exchanged, or otherwise disposed of any digital assets during the year. Answering “no” when you had taxable crypto transactions is treated as a false statement on a tax return, which can increase penalty exposure.

What is the tax treatment of staking rewards and mining income?

Staking rewards and mining income are taxable as ordinary income at fair market value on the date received (Revenue Ruling 2023-14). For miners, this is also subject to self-employment tax if mining constitutes a trade or business. The cost of mining equipment is a deductible business expense (Section 179 or depreciation), and electricity costs are deductible against mining income. When you later sell the staked or mined tokens, you recognize capital gain or loss based on the difference between the sale price and your basis (the fair market value at which you originally recognized income). The holding period for capital gains starts on the date the tokens are received into your wallet.

How are cryptocurrency staking rewards and airdrops taxed?

Staking rewards are taxed as ordinary income at fair market value when you receive them, based on IRS Revenue Ruling 2023-14, which treats staking rewards as income upon receipt regardless of whether you sell them. Airdrops are also taxable as ordinary income at the time you gain dominion and control over the tokens, valued at fair market value on the date of receipt. Your cost basis in staking rewards and airdropped tokens equals the fair market value you reported as income, so if you later sell them, you only pay capital gains tax on any appreciation above that basis. Tracking cost basis across multiple wallets, exchanges, and DeFi protocols requires dedicated crypto tax software because the IRS expects specific identification or FIFO lot tracking for every disposition.
