Tax Rules and Mistakes: EDU #2615

April 15, 2026

Chris’s Summary
Jim and I are joined by Jake as we discuss tax rules and mistakes through two tax-focused PSAs before moving into listener emails. Jake covers a denied non-cash charitable deduction due to an incomplete Form 8283 and missing contemporaneous documentation, then walks through how estimated tax payments and safe harbor rules are calculated from prior-year tax liability. We then address listener emails on establishing home basis after a spouse’s death, how the senior deduction is reduced for married couples, and comparing IRA versus Roth withdrawal strategies.

Jim’s “Pithy” Summary
Chris and I are joined by Jake as we spend some time on two tax-focused PSAs from Jake before getting into listener emails. Jake walks through a tax court case where a non-cash charitable donation was denied because Form 8283 wasn’t completed correctly and the required documentation wasn’t done at the time—even though the donation itself was valid. This highlights how strict tax rules and mistakes around them can cost you. He also breaks down estimated tax payments—those quarterly amounts that show up on your return after you’ve already paid what you owed—and how they’re calculated off the prior year to get you into the safe harbor.

We then get into a situation involving a home purchased in the early 1970s, no improvements over the years, a spouse passing in a community property state, and now the question of what the basis actually is and how to determine it years later without anything documented at the time, which is more common than you’d think. There’s also a question on the senior deduction where the reduction ends up applying to each spouse, which changes the expected result. Finally, we look at two different withdrawal approaches using traditional IRA and Roth accounts over the next few years, and how those choices shift balances and taxes depending on how the income is sourced and what you’re actually trying to accomplish with it.
