## Background: Basis Identification & Why It Matters - For digital assets (crypto, tokens, etc.), **basis identification** determines your gain or loss—essential for accurate tax returns. Discrepancies between your own records and broker reports can cause mismatches. - Under **§ 1.1012-1(j)(3)(ii)**, “adequate identification” means distinguishing which units are sold or transferred (by date/time, purchase price, etc.). Typically, brokers’ info must match. Without clear identification, IRS rules assume an unfavorable calculation. ([irs.gov](https://www.irs.gov/irb/2026-15_IRB?utm_source=openai)) ## Recent Change: Extended IRS Relief Period Notice 2026-20 (IRB 2026-15, April 6, 2026) extends **temporary relief** for taxpayers to make “adequate identification” using their own records, even when brokers’ reports don’t match—so long as the tax‐payer’s books & records specify which units are sold, transferred, or disposed during the **relief period** (Jan 1, 2025 through Dec 31, 2026). ([irs.gov](https://www.irs.gov/irb/2026-15_IRB?utm_source=openai)) ## What You Should Do: Best Practices - Keep detailed logs whenever acquiring digital assets: record **date/time**, **amount**, **purchase cost**, and **where held**. - When disposing or transferring, match those specific units by referencing your records—not just broker statements. - Maintain both broker statements AND your own identification records; even if the broker reports something differently, you may rely on your own records during the relief period. ## Example Scenario > Jane owns five lots of a cryptocurrency, bought at different times and prices. She sells two lots on May 15, 2025. Her broker reports a generic cost basis across all lots. But Jane’s personal ledger clearly identifies Lot A (bought Jan 10, 2025, at $10/unit; 100 units) and Lot C (further back, different cost). Under the temporary relief, Jane can say she sold Lot A and Lot C per her books and avoid mismatches vs. relying on broker totals. As long as her records identify units before the transfer date. ## Risk & Limitations - The relief is **temporary**, only valid through **December 31, 2026**. After that, crypto‐holders must ensure broker and personal records align. - Inadequate or late identification disqualifies relief; IRS may take broker reports as authoritative. - If units haven’t been properly identified by transfer time, this exception does not apply. ## Action Checklist 1. Establish a system (spreadsheet, wallet trackers, or blockchain logs) to log each acquisition and sale/transfer in real time. 2. During tax season 2026, use Notice 2026-20 guidance to identify sold units by your internal records. 3. Consult with a tax professional if you’ve had many overlapping or mixed holdings to reorganize asset tracking. 4. Ensure that records are backed up, immutable, and can prove timing (timestamps help). This relief gives digital asset holders breathing room—but only until end of 2026. Clarity now saves you costly miscalculations later.
