In 2020, I have worked as both a sole proprietor / individual contractor with no employees and as a W2 part-time employee. I am 41 yrs old (under 50) and will have multiple streams of income in 2020:<UL><LI>$100K from 1099 contract work as a sole proprietor / individual contractor (from Jan 1-Apr 31)</LI><LI>$60K from a W2 as a part-time employee (projected through the entire year from Jan 1-Dec 31)</LI><LI>$85K in taxable short-term gains from stocks, dividends, and other investment income (projected through the entire year from Jan 1-Dec 31)</LI><LI>Projected Total Income for 2020: $245K from all income streams</LI></UL> I currently have 4 retirement accounts open:<UL><LI>a Solo (Individual) 401K (new account, balance: $0)</LI><LI>a Solo (Individual) Roth 401K (new account, balance: $0)</LI><LI>a Traditional IRA (existing account, balance: $280,000 of which $40,000 is in gains in 2020)</LI><LI>a Roth IRA (existing account, balance: $118,000 of which $18,000 is in gains in 2020)</LI></UL> I would like to maximize my tax deductions this year and move as much money as possible into both after-tax and tax-deferred accounts. My question includes:<OL><LI>Can I contribute up to a max of $57K (employee + employer portion) to my Solo (Individual) 401K AND a separate amount to my Solo (Individual) Roth 401K ? Is the max contribution limit of $57k total across BOTH the solo 401K and solo Roth 401K? Otherwise, what is the contribution limit on the Roth 401K? </LI><LI>Can I either:<UL><LI>(Ideally) Contribute up to a max of $57K (employee + employer portion) to my Solo (Individual) 401K AND an additional $37,500 to a Mega Backdoor Roth? Or...</LI><LI>Contribute up to a max of $57K (employee + employer portion) to my Solo (Individual) 401K AND an additional $6,000 to a "regular" Roth? Or...</LI><LI>Contribute up to a max of $57K (employee + employer portion) to my Solo (Individual) 401K AND an additional $6,000 to a Traditional IRA?</LI></UL></LI></OL>What can and can't i do? My goal is to deduct / defer the maximum amount possible. Note: I tried to do my research before asking this question.
