Tax Filing Deadline for Cryptocurrency Investors
Cryptocurrency investors in the United States who applied for an extension on their taxes are nearing the crucial cutoff date of October 15, 2026, for their 2025 federal tax filings. Originally, taxes owed were due by April 15, and although an extension allows for additional time to file, it does not defer the requirement to pay any taxes owed by that date. Since the April deadline, interest and late-payment penalties have been accruing on any unpaid tax balances.
Understanding Extensions and Deadlines
This October deadline is specifically for those individuals who secured an extension for their 2025 federal income tax returns, not a blanket extension applicable to all U.S. taxpayers holding cryptocurrencies like Bitcoin or Ethereum. According to IRS guidelines, April 15, 2026 remains the general deadline for most calendar-year taxpayers, while automatic extensions culminate at the October cutoff. A Form 4868 extension only alters the filing timeline; taxpayers still needed to estimate and pay any owed sums by the original April deadline to avoid late penalties and interest, which continue to accumulate.
New Reporting Requirements
Illuminating the 2025 tax season is the introduction of Form 1099-DA, which custodial brokers now use to report gross proceeds from the sales of digital assets starting January 1, 2025. This is a significant shift, as while the IRS obtains more detailed transaction records, there is still a lack of information regarding the cost basis—what the investor originally paid for their assets—which is crucial for determining taxable profits. For instance, an investor who bought crypto at $8,000 and later sold it for $10,000 would need to calculate their profit starting from that $2,000 difference.
Challenges for Crypto Investors
The incomplete information on many Form 1099-DAs is causing headaches for numerous crypto investors who are preparing their taxes. An August survey highlighted that 21% of respondents who filed an extension were still waiting for data from their exchanges. It is important to note that even without receiving a Form 1099, taxpayers must report any taxable income, gains, or losses as stipulated by IRS regulations. This makes it crucial for crypto investors to keep accurate records of all transactions, as the IRS formally includes digital assets in its 2025 Form 1040 tax return, requiring all filers to answer a specified question regarding digital assets.
