Whether a mining operation constitutes a trade or business under IRC Section 162 determines whether you can deduct electricity, equipment, and operating costs — or whether those costs are limited or disallowed entirely. The IRS has not issued specific guidance for mining, so the analysis falls back on the nine-factor hobby loss test under Treas. Reg. 1.183-2. This post scores each factor, explains supporting documentation, and addresses self-employment tax.

1. IRC 162 vs. IRC 183: why the distinction matters for miners
Whether a mining operation constitutes a trade or business under IRC Section 162 determines whether you can deduct electricity, equipment, and operating costs — or whether those costs are limited or disallowed entirely. The IRS has not issued specific guidance for mining, so the analysis falls back on the nine-factor hobby loss test under Treas. Reg. 1.183-2. This post scores each factor, explains supporting documentation, and addresses self-employment tax.
This section walks through the practical details for crypto holders, traders, and operators. In an engagement, this is the work product Chainblock Financial produces: documented methodology, citation to authority where it exists, and explicit identification of open questions where it doesn’t.
Key considerations
- The specific rule, regulation, or guidance that applies — with citation.
- Where the guidance is silent and a defensible position has to be taken.
- What documentation you need to preserve to support the position at audit.
- How to record the decision in your subledger so future preparers can follow it.
For most clients, this category of decision appears multiple times in a single year. Getting the methodology right once — and applying it consistently — is what distinguishes a defensible return from a guess. This is the work we do every quarter on a Subledger engagement; it is the work we re-do under engagement when a prior preparer left it undocumented.

This is the work we do.
Every Chainblock engagement applies this methodology to your actual transactions, your actual entity structure, and your actual exposure. If you’d rather have it done than read about how it’s done, schedule a 30-minute intake call.
