6 Tax Rules Crypto Miners and Node Operators Get Wrong Mining and running a node create a tax problem that trading does not. A trader has one taxable event per disposal. A miner has two per coin, and the first one happens on a day the miner usually was not paying attention. Crypto mining taxes go wrong in predictable places, and almost all of them come from the same root cause: treating a stream of small receipts as if it were a single annual number. Here are the six that show up most often, and what each one actually costs. 1. Treating Mined Coins as One Taxable Event Instead of Two This is the foundational error. Under IRS Notice 2014-21, coins received from mining are ordinary income at their fair market value on the date received. That value then becomes your cost basis in the coin as property. When you later sell or swap it, you have a second, separate event, a capital gain or loss measured against that basis. So a coin mined at $40 and sold at $150 produces $40 of ordinary income in the year it was mined and $110 of capital gain in the year it was sold. Miners who report only the sale understate income in year one. Miners who report only the mining income overstate gain later, because they forgot they already paid tax on the first $40. The same logic governs staking and validator rewards. Rev. Rul. 2023-14 holds that staking rewards are income when the taxpayer gains dominion and control over them, which for most node operators means at receipt, not at withdrawal. 2. Assuming It Is a Business When the IRS Would Call It a Hobby The hobby versus trade-or-business distinction used to be an argument about deductions. It is now much harsher than that, because the OBBBA permanently eliminated the miscellaneous itemized deductions that hobby expenses once fell under. The practical result: if your mining is a hobby, the income is still taxable and the electricity, hardware, and hosting costs are effectively not deductible. If it is a trade or business, it goes on Schedule C, the expenses come off, and you also pick up self-employment tax on the net. Neither answer is automatically better, which is why guessing is expensive. Business treatment usually helps a real operation with meaningful costs. Hobby treatment can be less painful for someone with one rig, low expenses, and no interest in self-employment tax. The determination turns on facts like continuity, profit motive, recordkeeping, and time spent, not on what you would prefer. 3. Depreciating Rigs Without Checking Which Rules Apply Mining hardware is depreciable property if the activity is a...
