The income of a spouse has no affect on Social Security Disability Insurance—SSDI—benefits if you are filing for disability under your work record. This holds true no matter how much your future spouse earns or whether or not he or she is receiving disability benefits.
However, Supplemental Security Income—SSI—regulations are different. Because this is a program for people with low-income or no-income, your family earnings and assets can affect your benefits. Once you get married, Social Security will count your new spouse’s income as your income as well. Social Security may reduce your monthly payment or maybe even completely stop your benefits.
