Estimated Tax Payments for quarter two are due. Hi, I'm Bette Hochberger, CPA, CGMA, and on today's Tax Tip Tuesday, this is your reminder to pay your second 2021 quarterly estimated tax payment if you're somebody who needs to pay those; many people don't pay them. If you only have a job where you get a W2, and you're on the payroll, you probably aren't making estimated payments, but if you're a business owner or a freelancer, something like that, you probably have to make these payments. So how do you know how much to pay? That's always the question. People always want to know; how do I even know?
