Just a quick reminder that quarterly estimated tax payments are due this Friday, June 15th. If you have income that’s not subject to withholding (e.g., self-employment, interest, dividends, gains from the sale of assets, rental income, etc.) then you might need to make quarterly payments to avoid an underpayment penalty.
You can either use IRS From 1040-ES or the Electronic Federal Tax Payment System. I’ve always used the former, although I should probably check out the latter. And don’t forget that you might also need to make estimated payments for your state taxes.
