What is the deadline for making my SEP contribution if I file for an extension? Is the answer different for a partnership?

Is the deadline for making a SEP contribution from a two member LLC the same as for a self employed individual and can this be done up until the tax filing extension deadline of October 15, 2025?

The partnership can make a SEP contribution up to the due date of the company tax return, including extensions, or October 15, 2025 in your case it appears.

If a request for extension is timely filed, the deadline to make the SEP contribution is 6 months after the regular filing deadline.  For calendar-year filers who have timely requested a filing extension, the deadline to make the SEP contribution for 2024 is October 15, 2025 for sole-proprietors and September 15, 2025 for a partnership.
