Sure. Various tax measures that either have recently been enacted or are being considered or debated in the public sphere don't have any obvious...or at least from the superficial level, they do not look like they speak much at all to gender.
One example--and I think it was debated during the last election--is the possibility of having a change to reduce the taxation of capital gains. On first glance, that does not look like it has an obvious gender connotation, except if you are able to discern whether there's a pattern in terms of who has capital gains. Is it more likely to be men or women who have assets that they are able to sell at a profit and thereby realize a capital gain?
So if you were able to do the research that figured out the likely beneficiaries of such a tax, there's going to be a discernible pattern in terms of gender, then you have a different lens through which to debate that possible policy proposal.
The various tools in the toolbox would help you parse these things so before you even enact them, you can foresee the possible consequences in terms of gender equity.
