Tax Deadline This Year. Name the form you file
Thursday is not a mood. It is a day that belonged to two specific extended returns, and that day has passed. It belongs to no other return by default.
Two forms can share Thursday
An extended 2025 individual return and an extended calendar year Form 1120 can both point at Thursday 15 October 2026. Sharing a weekday does not make them the same return. One reports a person's year. The other reports a C corporation's year. If you have both, you have two jobs that happen to share a day.
An S corporation return and a partnership return do not join that pair just because October is close. Their extended day was Tuesday 15 September 2026, and it has passed. Saying the form out loud is what keeps Thursday from being borrowed.
If you are not sure which of those forms you file, that uncertainty is welcome in the form on this page. We would rather sort it on the call than have you prepare the wrong one over a weekend.
The payment is a second form question
Every one of those returns has a filing day and a payment day, and the extension only moves the first. For the individual return and the C corporation return, the payment day was Wednesday 15 April 2026 unless a different rule you can point at says otherwise. For the S corporation and the partnership, estimates and the entity's own payments follow their own lines. The point is the split, not a single number.
Write down, before the call, whether April was paid, partly paid, or not paid. You do not need a speech. A line on a notepad is enough. We will not scold a blank. We will ask, because the signature date cannot answer the payment question.
Safe harbor estimates are the same kind of split. The January payment can be sized from last year's tax under the published rule, including the higher percent when income crossed the published line. The form you file tells us whether that estimate even belongs to you.
Information returns are not this form
Forms W-2 and 1099 had a January day of their own. An extension of the income tax return did not file them. If a worker or a contractor is still missing a form, put that in the note as a separate job. Payroll that we set up with your provider is what produces those forms in a normal year. The provider runs them. We do not.
A notice that quotes a form number is useful precisely because of that number. Photograph the first page if you want, but do not send an identification number through the website form. Bring it to the call.
The page that walks the whole calendar, form by form, is which day is still ahead. The page about April as a finished day is April behind you.
After the form has a name
Once the form is named, the sequence is ordinary. Close the month. Reconcile the bank to the books. Set payroll up if a provider does not already have it. Draft the return from months where the ledger and the bank already share one balance. Talk through what the open year can still change, and leave alone what it cannot.
The sequence does not need a setting. It needs a form, a day, and a month you can stand behind. The engagement starts when the scope is signed, not when this website form is sent.
If you already know the form, you can go straight to a time this week. If you want a checklist for the table, read what to bring first.
Name the form on your notice.
If a notice is in your hand, name the form and the year. Leave account numbers off this page.
You will be talking to the Steven Palmieri practice.
