Hi humans — Tootsie here, your loyal, biscuit-motivated Chief Retirement Sniffer-Outer , reporting for duty. 🐶 Today we’re digging into something important that sneaks up on retirees faster than the mailman: Required Minimum Distributions , better known as RMDs . If you have Traditional IRAs, 401(k)s, 403(b)s, SEP IRAs, SIMPLE IRAs, or other tax-deferred retirement accounts , the IRS eventually requires you to start withdrawing money.

And yes, the IRS checks. Closely. Think of it like when my mom opens the treat jar and says, “Tootsie, you HAVE to eat one.” I might want to save my biscuit for later, but the rule is the rule.
