I used to be a contractor (1099) in 2014, but have been a W-2 employee all of 2015 and 2016, I work for a startup that I am not the owner of, they pay me as a w2 employee.
In 2015, I maxed out my Solo 401(k) through Vanguard. I was wondering if I can use my Solo 401(k) contribution as a tax write-off for my W-2 earned income?
I read this, but can't decipher the answer within there: https://www.irs.gov/Retirement-Plans/One-Participant-401(k)-Plans
Thank you for your help.
