Integrate Bitcoin into financial operations

Buying Bitcoin is the exciting part. Integrating it into the company's financial operations is the boring part — and it's where most of the actual work lives. Every reporting period, Bitcoin has to be valued, disclosed, taxed, and audited like any other asset. The good news: recent rule changes have made this much cleaner than it used to be.

Fair value accounting — the rule change that matters

Until recently, corporate Bitcoin was accounted for as an intangible asset with impairment-only treatment. In plain English: if the price dropped, the company had to write down the value on its books. If the price recovered, the company couldn't write it back up until the Bitcoin was sold. The books only ever moved one direction — down.

That rule punished honest reporting. It's been replaced. Under ASC 350-60 (effective for fiscal years beginning after December 15, 2024), companies now measure Bitcoin at fair value at every reporting period, with the change in value flowing through net income. Up moves and down moves are both reflected.

Internal controls

Bitcoin is easy to move — a single signed transaction can send millions across the world in ten minutes. That's a feature for the network and a risk for the company. Strong internal controls turn that risk into a manageable one.

• Segregation of duties — the person who initiates a Bitcoin transaction should never be the same person who approves it. The person who approves shouldn't be the one who reconciles. Split the roles.
• Multi-signature approvals — as covered in Lesson 5, wallets configured so any transfer requires multiple signatories. This is the cryptographic version of a co-signed check.
• Regular reconciliations — reconcile ledger balances against actual custody balances on a set schedule (monthly at minimum, weekly for larger positions). Discrepancies get investigated immediately.
• Audit trail — every transaction, wallet change, and access event is logged, timestamped, and preserved. Internal and external auditors will ask.

Tax treatment

In the United States, Bitcoin is classified as property for tax purposes. That means:

• Capital gains tax applies to sales and exchanges. If the company sells Bitcoin, or exchanges it for another asset, the difference between the purchase price and the sale price is a taxable event.
• Using Bitcoin to pay for something is also a taxable event. If a company pays a supplier in Bitcoin at a higher price than it originally acquired the Bitcoin, that's a realized gain.
• Holding Bitcoin is not taxable. Simply owning it, with the price moving up or down, doesn't create a tax event on its own — though it does now flow through net income for financial reporting.
• Detailed records are required. The IRS expects a complete history of purchase dates, prices, and dispositions. This is where the transaction logbook from Lesson 6 becomes essential.

Working with auditors

External auditors will want to verify three things: that the Bitcoin actually exists, that it's valued correctly, and that the controls around it are strong. Give them what they need up front and the audit gets much shorter.

• Existence — proof-of-holdings documentation from the custodian, plus wallet address confirmations if self-custodied.
• Valuation — market-price sources used to determine fair value at each reporting date, and consistency of methodology period-over-period.
• Controls — the internal-control framework: multi-sig setups, access lists, approval logs, reconciliations.

Schedule regular check-ins with the auditor — quarterly is common — instead of dumping everything on them at year-end. Auditors who understand the Bitcoin strategy in real time raise fewer surprises later.

Disclosures

Public companies now include Bitcoin holdings in their financial statement footnotes. Standard disclosures include:

• The nature and amount of Bitcoin held.
• How it is accounted for (fair value under ASC 350-60).
• The valuation method used.
• Any material impact on earnings from Bitcoin's price movement in the period.
• Custody model and any material custody risks.
