Click the Enter Amended Quarterly Tax Return
selection in the TAXATION area of
the application. The system displays the Filing History for the account.

Note: ONLY quarterly returns that are due and can be filed since the effective date of the account are presented on this version of the Filing History page. For a list of all returns and whether they can be filed or amended, please select View Filing History instead.
Press Amend to amend a return, starting with
the Data Entry page. This is the same for either IFTA or
MCFT.
If Amend is pressed in the Quarterly Return Filing History
Pane, a blank tax return page will be displayed for adding
changes to the return. The original return is not displayed.
It is not necessary to enter
the entire return – just enter the information that should be changed.
The Amend Quarterly Tax Return page is
very similar to entering a new quarterly return. Place the cursor in the data
fields that need to be changed, make the change necessary, and click on Continue at the
bottom of the page to file the return.
If the return is still incomplete click on Save and Exit at the
bottom of the page.
