If you've been in US for more than 5 yrs, i think you have to pay all your taxes while on OPT.
The link I've provided says "As discussed above, this means that foreign students in F-1, J-1, M-1, Q-1 or Q-2 nonimmigrant status who have been in the United States less than 5 calendar years are still NONRESIDENT ALIENS and are still exempt from social security/Medicare taxes. This exemption also applies to any period in which the foreign student is in "practical training" allowed by USCIS, as long as the foreign student is still a NONRESIDENT ALIEN under the Code. Foreign students in F-1, J-1, M-1, Q-1 or Q-2 nonimmigrant status who have been in the United States more than 5 calendar years are RESIDENT ALIENS and are liable for social security/Medicare taxes (unless they are exempt from FICA under the "student FICA exemption" discussed below)"
