Disability benefits are funds provided from public or private sources to a person who is ill or who has a disability. In the United Kingdom disability benefits are covered by Department for Work and Pensions.There are numerous benefits available for people of different ages and different personal circumstances In the United States, disability benefits for most Americans are covered and paid for by the Social Security Administration (a government agency). There are two main programs administered by the SSA; Social Security Disability Insurance program (SSDI) and the Supplemental Security Income (SSI) program. There is also a specific program for children with disabilities. Social Security Disability Insurance provides benefits to individuals who have worked and paid Social Security taxes. Insurance eligibility is dependent upon Quarters of Coverage (QCs), commonly called 'work credits'. These are allotted based on the earnings for each quarter the individual has worked. Work credits ensure coverage until they 'expire' on the individual's Date Last Insured (DLI). Medical evidence must prove that the onset of disability was before their DLI to receive benefits. SSDI recipients become eligible for Medicare after two years of SSDI eligibility. Supplemental Security Income (SSI) provides benefits to low-income individuals who are disabled and unable to work, regardless of whether they have worked in the past. Individuals must meet income and resource requirements. SSI also provides benefits to children under 18 years old, who are disabled and whose parents or guardians have limited income. The monthly SSI payment is calculated based upon the Federal Benefit Rate (FBR), and the individual's income. Most SSI recipients are immediately eligible for Medicaid and Supplemental Nutrition Assistance Program (SNAP), though program requirements vary by state. Some individuals are eligible for both SSI and SSDI. In Canada, there are a variety of public Disability Benefit Programs. The largest programs are the Canada Pension Plan and Quebec Pension Plan disability benefits, and provincial workers' compensation and social assistance programs. Some individuals, in addition, have private disability insurance coverage, purchased either individually, or through an employer. Different programs use different rules to decide whether or not someone is eligible for benefits. To access Canada Pension Plan or the Quebec Pension Plan disability benefits, an individual needs to have a disability that is 'severe and prolonged', and which prevents them from working on a regular basis. As of 2018, CPP disability benefits are a minimum of $485.20 a month. Individuals who have contributed more to CPP or QPP during their working career receive higher benefits. The average monthly CPP disability benefit was $971.23 in 2018 and the maximum monthly amount was $1,335.83. People receiving CPP disability benefits may earn up to $5,500 a year without losing their benefits. Benefits stop when an individual has the ability to work regularly, or is no longer disabled. When an individual reaches the age of 65, CPP Disability Benefits are replaced by a Retirement Pension.
