Analysis: Cryptocurrency Tax 'Turning Point' Looms as 2026 Tax Season Could Become Minefield
BlockBeats News, December 31st, as 2026 approaches, U.S. crypto investors are about to face a vastly different tax reporting environment. Several new regulations will take effect in the 2025 trading year and the 2026 tax season, collectively referred to by the industry as a "watershed moment" for crypto taxation.
One key change is the Form 1099-DA. Starting in 2025, U.S. centralized exchanges and other "brokers" will be required to report users' crypto asset sales and dispositions to the IRS, with the first 1099-DA forms set to be sent out in 2026. Initially, the forms will mostly include the sale amount (gross proceeds) without the cost basis. If taxpayers fail to report this clearly on their own, the IRS may default to a cost basis of zero and automatically issue tax notices.
Meanwhile, the "specific identification cost basis" will replace the previously common "first in, first out" (FIFO) algorithm. The IRS mandates that each trading platform account or wallet separately track cost basis, and upon selling, assets can only be matched with batches within that specific wallet. This will have a significant impact on users with multiple exchanges, DeFi, and self-custody setups.
Industry tax experts point out that reconstructing historical ledgers, organizing all on-chain and off-chain transaction records, will be a one-time but extremely laborious undertaking. Although the IRS has provided a transitional safe harbor in the 2024-28 numbered procedures, the compliance window is short, and very few investors have truly completed this process.
Tax experts warn that without early preparation, the 2026 tax season could result in "automatic triggers" due to data mismatches. Under a more data-driven and stricter IRS oversight, proactive record-keeping, early planning, and collaborating with tax professionals familiar with crypto assets are becoming a "required course" for crypto investors.
