As a certified benefits planner we don’t get much training around VA benefits and I’ve been getting a lot of questions about this recently. So far from what I’ve researched you can receive both VA benefits as well as SSDI or SSI. It appears that SSI can be impacted by the amount of VA benefits received but not SSDI. The VA benefits do not appear to be impacted by the SSI or SSDI amounts. Here is a link to an SSA document comparing eligibility requirements for VA benefits and SSDI: https://www.ssa.gov/pubs/EN-64-125.pdf
