What is an amended tax return?

An amended return is a correction filed after your original return has been submitted. For individuals, it is Form 1040-X. For businesses, amended returns use the equivalent forms for the entity type (1120-X for corporations, amended 1065 or 1120-S for partnerships and S corps). You amend when you discover an error, missed deduction, or incorrect filing status that affected your tax liability.

When should I file an amended return?

You should amend if you missed significant deductions, reported incorrect income, claimed the wrong filing status, forgot to include a K-1 or 1099, or made an error that changed your tax liability. Generally, you have three years from the original filing date to claim a refund through an amendment. If the error would increase your tax, amending proactively can reduce penalties.

Will filing an amended return trigger an audit?

Filing an amended return does not automatically trigger an audit, but it does draw scrutiny to the changes being made. This is why amendments should be prepared by a CPA who can substantiate every change with documentation. A well-documented, legitimate amendment is a routine filing; a sloppy or aggressive amendment without support is what invites problems.

Can you amend a return that another preparer filed?

Yes. We frequently review returns prepared by other preparers or tax software and file amendments when errors are found. We start by reviewing the original return, identifying mistakes or missed opportunities, and determining whether an amendment would result in a refund or correct a liability. If the amendment is not beneficial, we will tell you.

How long does it take to get a refund from an amended return?

Amended returns take longer to process than original returns, typically 8 to 16 weeks for the IRS, plus additional time for Illinois state amendments. We track the status and keep you informed throughout the process. If the amendment results in an additional refund, it will be issued once processing is complete.

Recover What Was Missed

If your prior return was prepared by tax software, a franchise chain, or a preparer who rushed, there is a real chance deductions were missed, income was misreported, or the entity structure was not optimized. A CPA review can identify these errors, and an amendment can recover the refund you are owed.

David Korzeniowski, CPA reviews the original return line by line, identifies every error and missed opportunity, and determines whether an amendment makes financial sense. If the refund justifies the effort, we prepare and file the amendment with full documentation. If it does not, we tell you, honest advice is part of the service.
