No. If you previously submitted a tax return and need to adjust any information on that return, you must file an amended tax return. For security reasons, amended returns must be filed on the paper form. You will need to check the “Amended Return” box on the form. Mail your amended tax return along with supporting documentation to Keystone Collections Group. Access our mailing addresses. Sign and date the return.

The Tax Officer is prohibited from making changes to your return. You or your tax preparer must complete the form.
