Hey there, @dcdc. Thanks for joining the Community.
I'm happy to clarify how QuickBooks Self Employed calculates taxes. We calculate estimated taxes for self-employed users with service-based businesses. We calculate your federal quarterly payments for you. We don’t calculate other types of tax estimates or more complicated tax scenarios, such as state income tax, sales tax, AMT, one-time lump-sum distributions, or tax credits. If you need to calculate these types of taxes, it's best to consult with an accountant.
Please reach out if there's anything else I can do to help, I'm determined to be your number one resource for QuickBooks Self-Employed. Have a great week!
