Need a quick checklist to get your June 15 estimated payments done on time? Here’s your roadmap.
👉 Federal (IRS):
→ Mail a check that’s postmarked by June 15, 2026, with your SSN in the memo line (and spouse’s, if filing jointly).
→ Or pay electronically via EFTPS (Electronic Federal Tax Payment System).
👉 Minnesota (S‑Corp, C‑Corp, Partnership):
→ Log in to MN e‑Services, choose Corporation Tax → Make a Payment → Estimated Payments, and set the date to 6/15/26.
Once you’re done, email Carefree Bookkeeping with the payment date(s) and amount(s) so we can keep your books and tax records aligned.
