I'm glad I was able to help. Sorry if I wasn't as clear as I could have been. FICA includes OASDI (social security) and Medicare. The 6 month clock starts from the date you stopped working due to your disability. So its possible both STD and LTD were paid during that time. Once you reach 6 months of disability, neither OASDI nor Medicare should be withheld. If your LTD did not begin paying out until 6 months after your disabling event, then no FICA would be withheld. If you feel you should still be paying FICA taxes, and they are not withholding, you may want to contact the provider of your disability insurance.
This continues until such time as you work again. The 6 month period does not restart each year. It would only restart if you return to work, then go back on disability.
