Why did my spouse and I get two different letters about our advance CTC payments?
If you filed taxes together with your spouse last year and claimed a child for the Child Tax Credit (CTC), the IRS should have issued you monthly CTC payments for your child. Even if you and your spouse filed your taxes together, the IRS treated those payments as if they were going half to you and half to your spouse. The IRS applied this logic in the letters they sent about advance payments. For example if your family got $1,500 in CTC payments, the IRS would send two letters, one to each spouse, reporting $750 of payments each. If you are filing jointly again for 2021, hold on to both letters and report the total payments from the letters added together.
If you and your spouse have divorced or have chosen to file taxes separately, you should each report only the payment amount from your individual letters.
