I am thinking of contributing to a SEP-IRA and immediately convert it to Roth (SECURE act allows Roth contributions to SEP-IRA but it seems non-trivial to set this up with Vanguard, etc., hence the backdoor conversion).
With the conversion to Roth, the SEP-IRA contributions will be taxable income, but I am wondering if the SEP-IRA contribution will still reduce my "net" self-employment income, which in turn would reduce the Qualified Business Income tax savings?
