Is a token approval a taxable event?
No. An approval grants a contract permission to spend tokens from your wallet later; no tokens move, nothing is disposed of, and no income is received. The only economic content is the gas paid to record the permission. CryptoTaxEdge serves approvals as identification rows, free on every plan, never billed classifications.
Key takeaways
- An approval grants spending permission; no tokens move, nothing is disposed of, and no income arises.
- The gas that recorded the approval is the only reportable item, under the ordinary fee doctrine.
- Approvals are identification rows, free on every plan, never billed classifications.
What an approval actually does
An ERC-20 approve call sets an allowance: it authorizes a contract to move up to a stated amount of your tokens in some later transaction. Setting an allowance, raising it, or revoking it changes permissions, not ownership. Nothing is exchanged, so there is no disposition under IRC §1001, and nothing is received, so there is no income under IRC §61.
The gas fee is the only reportable item
The gas that recorded the approval was really spent. It is a cost of executing, and whether it is deducted or capitalized depends on the taxpayer's activity classification -- the preparer's call, not the classifier's. One documented limit applies to every fee row: the fee leg is carried as display-only data, so gain or loss on the fee asset itself is not booked in these records; if the books require it, compute it outside them.
How the wire represents an approval
There is no approval category on the wire. Approvals are served under fee_payment with the expense treatment, distinguishable from an ordinary fee in the record's description prose; review_note is null on non-review records. That is a documented gap in the Classification Standard (GAP-5), published rather than papered over, and the review contract is unchanged: a served treatment is asserted, and anything the engine will not assert routes to needs_review with taxable null.
Approvals never touch a quota
An approval is an identification-grade shape: naming it correctly requires no tax judgment, so it is served free on every plan and never counts as a billable classification.
Max-allowance approvals, revokes, and re-approvals
Wallet histories accumulate permission churn: an exact-amount approval before one trade, a max-allowance approval to skip future prompts, a revoke after a security scare, a fresh approval next season. Every one of these is the same event for tax purposes -- a permission write with a gas fee -- and none of them creates a lot, closes a lot, or recognizes income. The allowance amount is invisible to the tax outcome: a max-allowance approval and a one-token approval differ in risk posture, not in tax character. Off-chain permit signatures go one step further: a signed permit that is never used lands no transaction at all, so there is nothing to book until a spend actually happens, and when it does, the permission rides inside the spending transaction itself.
When the spend finally happens
The transaction that later pulls tokens under the allowance -- the swap, the deposit, the listing sale -- is its own event with its own classification, and that is where any disposal or income lives. The approval's gas does not merge into it by default. Some preparers capitalize an approval fee into the acquisition it enabled; that is a method choice, made once and applied consistently, not something the on-chain record asserts. Reading the two rows separately, permission then spend, is what keeps an approval from ever being mistaken for the trade it made possible.
Frequently asked questions
What is a token approval?
An ERC-20 approve call sets an allowance: it authorizes a specific contract to move up to a stated amount of your tokens in some later transaction. It is how DEXs, lending protocols, and marketplaces get permission to pull tokens when you actually trade. The approval itself moves nothing; it is a permission write recorded on-chain.
Is revoking a token approval taxable?
No. A revoke writes the allowance back down, typically to zero, and moves nothing, so there is no disposition and no income. The gas paid to record the revoke is the only reportable item, under the same fee doctrine as the approval itself.
Are max-allowance token approvals treated differently for taxes?
No. The size of the permission does not change its tax character: a maximum allowance is still permission, not movement. The security considerations around max-allowance approvals are real but separate from tax; nothing is recognized until tokens actually move under the allowance, and that later movement is its own transaction with its own classification.
Can I deduct the gas I paid for approvals?
Approval gas is a standalone fee attached to neither an acquisition nor a disposal, so whether it is deducted or capitalized depends on the taxpayer's activity classification, and that call is the preparer's. Whichever method is chosen, document it and apply it consistently across the year.
