Capital gains tax is due in the tax year you sell an asset, reported on your annual income tax return (typically by April of the following year), but if you expect a large bill, you might need to pay quarterly estimated taxes to the IRS to avoid penalties. The gain is realized when you sell, triggering the tax obligation for that year, whether short-term (held 1 year or less, taxed as ordinary income) or long-term (held over 1 year, often lower rates).
Capital gains tax is typically reported and paid when you file your federal income tax return, due in April each year for individuals. There aren't any rules that require you to pay what you owe at the time you sell the asset.
For example, if you disposed of an asset and made a gain in January 2025, this would fall in the 2024/25 tax year (which ended on 5 April 2025), and you would be able to report the gain using the 'real time' service up to 31 December 2025. You would need to pay any CGT liability on this gain by 31 January 2026.

No, you generally cannot file a second automatic tax extension after the October 15 deadline; the IRS only grants one six-month extension (from April to October) per tax year, and missing the October date means penalties for late filing begin to accrue, unless you qualify for specific exceptions like being in a disaster area or military service. If you missed the October deadline, your priority is to file your return as soon as possible, even if you can't pay everything immediately, to minimize failure-to-file penalties.
