Employer changed payroll provider mid-year. Have two W2s now-- one for Jan-Jun and a second Jan-Dec.

Employer changed payroll companies mid-year.  Received a W-2 processed by the new payroll company that included all earnings for the year (includes income and taxes that the old payroll company processed.)  However, old payroll company also produced a W-2 for earnings for the first half of the year.

Do I need to wait to file until this is corrected?  W-2's. have the same EIN, just the amounts are different.  Will the IRS add the income on the two W-2's thinking I earned more than I actually did?
