Tax organizer checklist for a 1040 return
Individual clients rarely know which forms they need until the return is half done. This checklist lists the common documents for a Form 1040 return for tax year 2026, which is filed in 2027, grouped by where the paperwork usually comes from. In Usual's organizer, clients answer a few yes or no questions first and then see only the items that apply to them.
Who sends itSent to each individual client when the firm opens tax season for the 2026 return, with the firm's due date. Clients with a new job, a move, a home sale or a new business usually have more items on the list.

What firms get wrong
- Sending last year's organizer unchanged. A new job, a home sale, a new dependent or a business started during the year changes what the client owes.
- Chasing brokerage forms before mid-February. Composite 1099s and corrected forms often arrive later, so a client who sends an early version may send it twice.
- Letting clients type Social Security numbers into a note or an email reply instead of a secure field.
- Treating a missing item as no item. Ask the client to confirm that it does not apply.
- Forgetting the April 15, 2027 contribution deadline for an IRA contribution that counts for 2026.

Questions about this checklist
Is this the same as the organizer in Usual?
It follows the structure of the individual tax organizer in Usual. In the app, clients answer yes or no questions first and then see only the items that apply to them, so the list each client sees is usually shorter than this page.
Do clients have to send every item on the list?
No. Items marked optional only apply if the client had that income, expense or event in the year. If an item does not apply, the client should say so in a note so you know it was checked.
Should clients send Social Security numbers or account numbers by email?
No. Ask clients not to send SSNs or full account numbers by email or in a note. Use the secure answer fields or upload areas your firm provides, so sensitive numbers stay encrypted.
When is the 2026 federal individual return due?
The federal individual return for tax year 2026 is due April 15, 2027, unless an extension is filed. An extension gives more time to file, but it does not extend the time to pay any tax owed.
What if a client cannot find a form?
Ask the client to describe the missing document in the note, with the employer, bank or company that issued it. Many issuers keep copies in an online account, so the client can often download a replacement.
