Pass-through entities generally don’t owe federal income tax at the entity level, but they still must file federal income tax returns. These entities include partnerships, limited liability companies treated as partnerships for tax purposes and S corporations. If your pass-through entity uses the calendar year for tax purposes, as most do, the filing deadline for the 2025 tax year is March 16, 2026 (because March 15 is on a Sunday). The deadline can be extended to Sept. 15, 2026, by filing for an extension by March 16. If you do that, you (and any other owners) will also likely need to file an extension to Oct. 15, 2026, for your individual return.
