My question actually will apply to next year, but I need to plan. In 2018 I my marginal tax rate was 12%. In 2019 we received a lumpsum payment of social security disability that includes payments for 2018. In 2019 because of this lumpsum payment we will be in the 22% marginal tax bracket. While 85% of benefits are taxable, if I distribute disability income between 2018 and 2019, I will be saving over 1000 dollars in federal taxes because of this 10% difference in marginal tax bracket. I do not see anything that allows me to amend my return. All those lengthy calculations are to see if the taxable SSDI would be lowered. It does not see if the actual taxes are lowered. AT least that is my understanding after reading pub 915. Can someone tell me if I understood right? Thanks in advance
