I'd bet once you start digging down into the details, having a brokerage account becomes less and less relevant as a metric for who can pay simple taxes. For example, how many of those respondents in the Gallup poll answered yes only because they have a Simple IRA? For those respondents, their contributions don't preclude them from taking the "simple tax" branch when filing taxes. (That's the "simple" part-- well, one of the simple parts, at least for the employee.) Moreover, there were some changes to simple IRA administration in Secure 2.0 act that make automatic enrollment mandatory (for the employer to do 3% matching or whatever). So the category of respondent I mentioned above-- who technically has a brokerage account but can file simple taxes-- is likely to grow quite a bit in the next few years and decades. Edit: I'd also be interested in how many people with simple IRAs contribute anything more than the 3% matching-- I'd bet its more than a majority. Perhaps that could change now that Secure 2.0 lets them contribute to a Roth IRA.
