Diagnosed with Stage IV Lung Cancer March 1, 2022. I am on the Agent orange list and have just received a 100% rating. I have and still am undergoing Immunotherpy and well as 5 competed sessions of Chemotherapy and Radiation. I am making general assumptions here. I am retired navy an prior to the 100 % rating, I was at 40% so my military retirement was 60% taxed and 40% tax free. Now I assume my disability pay will be such that 100% of my military retirement will be tax free? Is that a correct statement? At one time many moons ago weren't retirees receiving disability from the VA and still collecting their military retirement too? Am I on the right track here? Any other things I should know right off the bat?
