at the beginning of 2025, I had nothing in Traditional IRAs, only Roth IRAs. I make too much for a deductible Traditional IRA so made a non-deductible contribution to a Traditional IRA then immediately converted it to a Roth (aka backdoor Roth). Later in the year, I took an old 401(k) I had from a previous employer and did a Rollover IRA. Let's say the backdoor was for $8500 and the Rollover IRA was $100000 at the end of 2025. What are the tax implications? Is most of the $8500 considered taxable income? I had done the backdoor many times previously with no additional tax due but all of my pre-tax money was in 401(k)s.
