NFT cost basis: lots, gas, and the “when did you actually own it” question

NFTs Cost basis Creator economy

NFT taxation is property taxation under current IRS guidance — but applying the property rules requires answering questions that don’t arise with fungible tokens. When does title transfer in a minting event? Does gas paid during a failed mint establish basis? Are creator proceeds ordinary income or capital gain? What’s the correct basis for an NFT received as barter for creative services? This post works through the tax treatment for collectors, creators, and anyone who has done both.

1. The basic framework: NFTs as property, the general rules that apply

NFT taxation is property taxation under current IRS guidance — but applying the property rules requires answering questions that don’t arise with fungible tokens. When does title transfer in a minting event? Does gas paid during a failed mint establish basis? Are creator proceeds ordinary income or capital gain? What’s the correct basis for an NFT received as barter for creative services? This post works through the tax treatment for collectors, creators, and anyone who has done both.

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.

2. Minting: when does acquisition occur and what constitutes your cost basis

5. NFTs received as payment: ordinary income at receipt, then capital gain on sale

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.
