Distilled for the individual from PwC's Crypto Assets Guide (a 100+ page manual written for corporate accountants). This is education, not accounting advice.
Three reasons. First, if you have a small business, an LLC, or you freelance and accept crypto, these rules touch you directly. Second, the accounting rules explain why public companies suddenly started buying Bitcoin for their treasuries. Third, the discipline of accounting (tracking what you paid, what it's worth, what you owe) is exactly the discipline that keeps individual investors out of tax trouble. The tax guide covers the IRS side; this covers the bookkeeping side.
Accountants define crypto assets as transferable digital tokens secured by cryptography on a blockchain. But classification matters: a token can be treated as an intangible asset, a financial instrument, inventory, or something else entirely depending on what rights it carries. A token that gives you a claim on gold gets accounted for differently than Bitcoin. A stablecoin redeemable for dollars looks more like a financial asset. The label follows the substance, not the marketing.
This is the headline. Under the old rules, companies holding Bitcoin used "cost less impairment" accounting: if the price dropped, they booked a loss; if it recovered, they could not write it back up until they sold. Bitcoin at a company like Tesla or MicroStrategy could only look worse on paper, never better. It made corporate crypto holdings ugly by design.
The FASB's ASU 2023-08 (Accounting Standards Codification 350-60) fixed this. Starting with 2025 financial statements:
Translation for the little guy: corporate balance sheets now tell the truth about crypto in both directions. That single rule change removed a major deterrent to companies holding Bitcoin, and it's part of why treasury adoption accelerated.
When you sell part of a stack you bought at different prices, which coins did you sell? Companies must disclose their method, and the common answers are FIFO (first in, first out) or specific identification (you point to the exact lot you sold). The same choice faces you at tax time. Specific identification usually gives the most control over your taxable gain, but it requires the records to prove it. Whatever method you use, use it consistently.
The corporate rules mirror the tax intuition: crypto received for goods or services is revenue at fair market value when received. Mining and staking rewards are recorded at value when earned. If you run a small operation, the bookkeeping is the same idea at smaller scale: record the dollar value the day the coins arrive, because that number becomes both your income figure and your cost basis going forward.
For a while, an SEC rule (SAB 121) forced platforms holding customer crypto to put those holdings on their own balance sheets as liabilities, which made custody brutally expensive for banks. That rule was rescinded in early 2025 (SAB 122), reopening the door for regulated institutions to offer crypto custody. It's part of why you now see traditional brokerages and banks offering crypto services they wouldn't touch in 2023.
Modern accounting finally treats crypto at honest market value, companies must show and explain their holdings, and the little guy wins by copying the same discipline: know your basis, track every lot, and keep your own records.
