Crypto Realized vs Unrealized Gain Accounts: Where Each Lands

Two crypto results look similar and behave completely differently: the realized result when you sell, and the unrealized remeasurement of what you still hold. They land in different places depending on the framework — net income under FASB ASU 2023-08, OCI or P&L under the IAS 38 revaluation model. This guide structures the accounts so the income statement is right, hedged, because it is a framework-driven judgement.

TL;DR

• Realized = on disposal (proceeds − cost basis − disposal fees); unrealized = period-end remeasurement of still-held crypto. Distinct accounts.
• US GAAP (FASB ASU 2023-08): in-scope crypto at fair value, changes (unrealized) in net income.
• IFRS (IAS 38): cost model (no upward unrealized) or revaluation model (increase → OCI, decrease below cost → P&L).
• Keep realized and unrealized separate — combined, one masks the other and disclosures break.
• Accounting split ≠ tax outcome — tax is jurisdiction-specific, adviser-confirmed.
• Framework- and model-driven auditor judgement. Not accounting advice.

Two different results

They can move in opposite directions in the same period, which is exactly why they need separate accounts (a core part of chart of accounts design).

US GAAP: unrealized → net income

Under FASB ASU 2023-08, crypto within scope is measured at fair value with changes recognized in net income each period (vs the prior cost-less-impairment model — see impairment vs fair value). The CoA needs an unrealized fair-value change account flowing to net income. The scope question is answered first (auditor judgement) — see FASB ASU 2023-08.

IFRS: it depends on the model

Under IAS 38:

• Cost model — cost less impairment; no upward unrealized gain recognized.
• Revaluation model — fair value; increases generally to OCI, decreases below original cost to P&L.

So an IFRS revaluation-model CoA needs an OCI revaluation account plus a P&L account — a different structure from US GAAP. The model choice is an auditor-confirmed policy (see crypto asset account classification).

Why separation is non-negotiable

Combined, a large unrealized gain can mask realized losses (or vice versa), and disclosures often require them shown separately. Separate accounts let the income statement distinguish completed disposal results from period-end remeasurement and let reconciliation tie each to its cause. Combining them is a frequent misstatement.

Accounting split is not the tax answer

Many jurisdictions tax on disposal (realized) and not on unrealized remeasurement — but this is jurisdiction-specific with exceptions, determined separately with a tax adviser. This guide structures the accounting accounts; it does not state the tax result (a YMYL question for the relevant jurisdiction).

Practical guidance

1. Create distinct realized and unrealized accounts — never one combined line.
2. US GAAP in-scope: unrealized fair-value change → net income (ASU 2023-08).
3. IFRS: settle cost vs revaluation; revaluation needs an OCI account too.
4. Answer the scope/model question first with your auditor — it sets the structure.
5. Keep the split for disclosure — they are reported separately.
6. Determine tax separately with a tax adviser — accounting split ≠ tax; not accounting advice.

How vendor tools handle the split

Cryptio and Bitwave post realized results and period-end remeasurement to distinct configurable accounts. Confirm the tool supports net-income vs OCI routing per your framework/model — the tool applies the routing; which framework and model apply is an auditor judgement.

How Wag3s helps

Wag3s Ledger posts realized disposal results and unrealized remeasurement to distinct accounts, routed to net income or OCI per the configured framework/model, with an audit trail and ERP export — while the scope, model, and recognition stay auditor-confirmed, and tax stays a separate adviser question. See the Ledger product page.
