IRS has set up a site to opt out of the advance child tax credit payments (if you opt out, you will receive the full amount your eligible for on your tax return next year instead). Or you can set up an account at IRS.gov & opt out in your account.

Unenroll if you don’t want to get advance Child Tax Credit payments or check if you’re enrolled.
