Social Security Taxes
Social Security and Medicare taxes are paid to cover the social security and medicare insurance. The employers use different abbreviations for this type of taxes - FICA, SS Soc, Soc Sec, Med, SS Med, Social Security taxes, Medicare taxes, OASDI, Fed OASDI, FED SS etc.
It is important to know that students who stay in the US under J, F, M or Q visa types, are not obliged to pay those taxes, they are mandatory only for legal permanent US citizens. If your employer deducted Social Security and Medicare taxes from your paychecks, this can be due to a mistake in the accounting system or ignorance.
If you have such taxes deducted and want to return them you can use Orange Tax Refund FICA!!!
