Yes, you need to include the W-2 on your taxes.
To aid with compliance, the IRS also receives copies of those
tax forms. If you fail to report a W-2, the IRS will know since it already
has its own copy. If you file a tax return without a W-2 you received, your
information will not match the records the IRS has. In the case of a form such
as a W-2 or a 1099-R, this will usually result in the IRS sending you a letter
requesting the omitted form.
