If I had no income due to a net operating loss, will I be refunded the Social Security and Medicare taxes withheld?
If you have a CPA working for you already - this is a question you should be asking that CPA. Generally, NOL only affects the tax stemming from the Internal Revenue Code (Title 26 Subtitle A of the US Code). Social Security and Medicare, while based on income, are not "income tax", these are different taxes stemming from different laws. Social Security and Medicare withheld from your salary are FICA taxes (Title 26 Subtitle C of the US Code). They're deducted at source and not on your tax return, so whatever changes you have in your taxable income on the tax return - FICA taxes are not affected by it. Self Employment tax (Schedule SE) on your Schedule C earnings in the carry-back years will also not be affected, despite being defined in the IRC, because the basis of the tax is the self-employment income while the carryback reduces the AGI.
