I always hear people talking about basis, itemized and AGI,

How detailed should I know sureties and agency rules?

Exoneration, surrogation, vocation, etc. should I know these and what’s a good summary or way to learn it

How often are amounts pertaining to a specific year tested?

Like how in 2025 you can’t exceed 236,000 - 246,000 of AGI for Roth contributions
