When john received his w2, he received several copies. why was he sent multiple copies of this form?

Because John has to file the copies of his W-2 to different institutions

One copy of the w-2 would be used for filing tax returns, one copy of the w-2 should be sent to the federal, state, and the local government for their record, and one copy of the w-2 should be kept by yourself in case you want to propose a tax return in the future.

Vanessa had a dream to be a ballerina. with her father's she had that opportunity.
