My pay periods are from 12/01/2015 - 12/15/2015 and paid on 12/30/2015. Wages for 12/15/2015 to 12/30/2015 are paid on the following 15th. If my wages are earned for pay period 12/15/2015 to 12/30/2015 they would still count toward my wages earned for 2015 even though they were paid the following year (1/15/2016), correct? I'm trying to find if my W2 was processed incorrectly. My employer is stating that it's not taxable for that year because it's being paid the following year. Is that correct?
