Quietly, the IRS Gave Crypto Investors Until December 31, 2026 to Rewrite Their Tax Basis. Most Have No Idea.
The IRS extended until December 31, 2026, the deadline for crypto investors to choose specific coins for tax purposes. The default is FIFO, but investors can opt for specific identification to minimize gains or maximize losses. Bitcoin (BTC) and Ethereum (ETH) have seen significant price declines, affecting tax outcomes. Notice 2026-20 allows standing orders for brokers until the end of 2026.
