Just helped a 24-year-old heir deal with a $200K crypto inheritance from his mother (died January 2026). He doesn’t know what he owns, how much tax he’ll owe, or when he should have started dealing with this. He asked: “Do I have to report it? It was hers, not mine. Am I being taxed on HER gains?”
Standard answer: yes, but your basis resets to FMV at her death (step-up in basis). He looked blank. I realized: he’s never filed his own taxes, doesn’t understand capital gains, and has no mental model for inheritance accounting.
How do you onboard young heirs on financial reality? Is Beancount even the right tool, or is this purely a tax education problem?
Crypto inheritance is a special kind of nightmare.
How many young people are even inheriting enough to matter, honestly?
he’s never filed his own taxes
This. The step-up in basis is the easy part—the hard part is explaining it when they don’t understand capital gains, tax years, or what a 1099 is.
Step-up IS automatic though, not optional. But the confusion is real: young heirs think “this appreciated $150K, I owe tax on that” when actually the FMV at death = new basis. They get the DATE wrong (inherit in March, think step-up happened in March, not January). Most never catch it.
I inherited my parent’s brokerage at 23. Didn’t understand step-up basis. Sold some shares a year later, paid capital gains tax on $80K appreciation—not realizing my basis had already reset. Took 3 years and a conversation with a CPA to recover.
Where do young heirs even learn this? High school? College? Parents don’t teach it because they never had to think about it.
