Almost climbed it on the 15th! In mid April IRS wall does not get shade until well past noon. Taxman and Evasion (just a different finish) are well deserved of their praise in Miramontes guide. Great positioning high up on the wall with the belay surrounded by boulders giving you a sense of quiet and peace mid week at least. Outside of the crux for Taxman down low, the only other crux on Tax Evasion is after you traverse out left. The first move up is easy, but maybe the 2nd move is 5.10b (what Miramonte has it at). Kind of an awkward mantel/stem deal. Definitely just one hard move then smooth sailing again. You will need medium gear for that traverse and definitely extend your placements to avoid rope drag. Rock quality on the traverse is a little crunchy.
