What IRS Form 1065 (2021) Is For

Form 1065 is an information return used by partnerships to report income, gains, losses, deductions, credits, and other tax information to the IRS (IRS Instructions for Form 1065 (2021)).

Partnerships generally don’t pay income tax directly; instead, they pass through profits and losses to their partners, who must report these items on their individual returns. Every domestic partnership must file Form 1065 unless it neither receives income nor incurs any expenditures treated as deductions or credits for federal tax purposes.

When You'd Use Form 1065 for 2021 (Late or Amended Filing)

You would file a late 2021 Form 1065 if you missed the original March 15, 2022 deadline or the extended September 15, 2022 deadline.

Common situations include:

• Receiving IRS notices about unfiled returns
  
  
• Discovering unpaid partnership taxes
  
  
• Correcting errors on the original return
  
  

Late filing triggers significant penalties of $210 per partner, per month (or part of a month) up to 12 months maximum (IRS Instructions for Form 1065 (2021)).

For amended returns, you would file corrections when:

• Partner allocations were wrong
  
  
• Income was understated
  
  
• Deductions were missed
  
  

Unlike individual returns, partnerships cannot claim refunds since they don’t pay entity-level tax, but corrections may affect partner tax liabilities and help avoid compliance issues.

FAQs

Can I still file my 2021 partnership return in 2024?

Yes, but penalties of $210 per partner per month apply, capped at 12 months. File quickly to minimize additional penalties.

How much are late filing penalties?

$210 per partner per month, up to 12 months. For example, a 2-partner LLC filing 18 months late would owe $5,040.

Do I need transcripts before filing late?

Yes, request IRS transcripts to check for prior filings, penalties, or notices.

Can partnerships claim refunds?

No. Partnerships don’t pay entity-level tax, so they cannot claim refunds. Corrections only adjust partner-level tax liabilities.

Do I need to amend my state return?

Most states require amended state returns if the federal return is amended. Rules vary by state.

What’s the difference between an amended return and an AAR?

• Amended return: Used to fix errors on Form 1065.

How long do I have to file an amended return?

Generally within 3 years of the original due date or filing date, whichever is later, unless statutes of limitations provide otherwise.
