Tax deadlines are closer than they appear

Carta put together a timeline of key 2026-2027 tax dates worth keeping on your radar, whether you're managing ISO exercises, equity reporting, or year-end filings.

One date that often catches teams off guard: November 3 is the deadline to request your TCC number if you plan to file 1099-Bs electronically. That's a prerequisite step, not the filing itself, so it needs to happen first.

Save this, share it with your finance or equity admin team, and let us know if you have questions in the comments.
