Lived in U.S. for approx 15 years paying SS Tax and worked in U.K. for approx. 4 years paying U.K. Retirement taxes. The rest of the time lived in England and received Disability Benefits. While receiving Disability in England, English Government credited contributions to U.K pension. but I made no contributions. Where do I stand with respect withholding . If withholding applies, which pension would be reduced? Thanks.
I don't know much about the UK pension system, but if your UK pension is based at least in part on your work there, it could result in a reduction in the rate of your US Social Security benefit. This is due to the windfall elimination provision (WEP). For more information on WEP, refer to this pamphlet: https://www.ssa.gov/pubs/EN-05-10045.pdf.
