Error F540/NR/2EZ-240 occurs when the Primary Taxpayer's Signature Date is not within the current processing year. This prevents the return from being filed.
How to Fix It:
Go to the Main Information Sheet in your tax return.
Locate the Signature Date field.
Update the date to reflect the current year.
Save your changes and try filing again.
By correcting the date, you should be able to successfully submit your return. If the issue persists, double-check that the year matches the current tax year.
