Estimated income lower than expected

Hello,

 

I have a quarterly estimated tax payment due in September and I've realized that my income for 2023 will be significantly lower than 2022.  Should I still pay the amount that is based on the 2022 income, or pay less?  Is there a way to determine the appropriate amount for a lower income, or is it best to just pay and then get a refund?

 

Thank you!
