Some states require more things than the Federal or other states require. Part of the reason is tax fraud, and when the W2G is entered, they may not have input the information from the issuer of the W2G yet, in the matching program they have and they want to ensure they are not issuing refunds for money that may have never been paid in. That is one reason. For example, IRS has issued refunds to some when the W2G when not valid and then they can't recover the money. ZA is trying to prevent that and they call some of the casinos to verify the amounts before the refunds are released (not all but a sample). the efile date transmitted does not transmit all the data.
