In order to receive SSDI (social security disability insurance) benefits, you must be “insured” for these benefits. This means that you must have paid into the social security system through the Federal Income Contribution Act (FICA). An individual must have worked a sufficient period of time to earn a requisite amount of quarters to be entitled to these benefits. Every year a person can earn up to 4 quarters. For 2017, 1 quarter of coverage is $1,300.00. This means you must earn at least $5,200.00 for 2017 in order to obtain all 4 quarters for the year.
