There are a couple of ways to estimate the payment. You can go to the 1040 worksheet, depending on if you're a business owner, if you are an LLC, it depends on what you are. So you can go to the 10 40 ES worksheet. And that worksheet is congruent with worksheets 2-1, or you can go to the 1120 W worksheet. And that also is congruent to 2-1. You use those worksheets together and you come up with the amount, the worksheet walks you through each line item of what you should put and where you should put it. If you prefer, you can use an estimated tax calculator. And the IRS has one and also Complyant has one. And the estimated tax calculator again is just an estimation, but it's just a quicker way to get to the number of what you owe for those time periods.
