I am preparing the FS-10-F for a grant that ended about a week ago. I now realize that the expenses related to the grant do not closely match the approved budget. Can I submit an amendment with the final report so that we can get reimbursed for all the ex

No. Amendments are required to be submitted and approved prior to the end of the grant. An approved budget is an expenditure plan to carry out the purposes of a grant, and an amendment is the authority to incur obligations under a revised expenditure plan. To assure expenditures are made according to an approved plan, amendments must be approved prior to the end of the grant.
