How do you know if your tax return is processed?

You can check the status of your tax return by using the IRS's "Where's My Refund?" tool on their website, which provides updates on processing and estimated refund dates. Additionally, you can set up an account on the IRS website to view your tax information. If you filed your return electronically, you might receive confirmation from the IRS once it's processed. Keep an eye out for any correspondence from the IRS regarding your return.
