A grantee must ensure that its final invoice is postmarked no later than the 45th calendar day (liquidation date as defined in the application package) after the end of the grant period and mailed to: OAG Grant Coordinator, 300 West 15th Street, 15th Floor, P.O. Box 12548, Austin, TX 78711-2548. If this date falls on a weekend or federal holiday, then the OAG will honor a postmark on the next business day. On the liquidation date, if grant funds are on hold for any reason, the funds will lapse and cannot be recovered by the grantee. Under no circumstances will the OAG make payments to a grantee who submits its invoice with a postmark after the above deadlines.
