Underpayment of estimated tax penalties two years in a row. I guess I've been been doing something wrong...

L'auteur a reçu une pénalité pour sous-estimation de ses impôts pour la deuxième année consécutive et cherche à comprendre comment éviter cela en faisant des paiements trimestriels.

After getting hit by my second year of underpayment of estimated tax penalty, I've been reading up on the need to make quarterly tax payments to avoid this penalty. I always assumed this was something only business owners and self employed needed to do. Is this something many of you all are having to do? Because I'm surprised I haven't seen it discussed very often here. Is it as simple as dividing my amount due this year by four and paying that amount each quarter for next year's filing? I know this is only tangential to bogleheads but I'm sure there are plenty here that have dividends (👎🏻👎🏻) pushing their unreported income over the safe harbor limit.
