A W2 form is an IRS tax form used in the United States to report wages paid to employees and the taxes withheld from them. It is an important document for both employees and employers. An employee's W2 form is used to file their annual income tax return. Without more context, it is unclear what "Artistoto" refers to in relation to the W2 form, and it is possible that it is a misspelling or a specific reference not widely known.
