What form is used to advise the employer of the number of federal exemptions to use in calculating an employee's withholding taxes?

That would be Form W-4. That's the one employees fill out to tell their employer how many allowances they're claiming.

Use a W-4. It's the IRS form that employees complete to show their withholding allowances, which affects the amount of federal income tax withheld from their wages. Gotta get that right so the employer is all square on taxes.
