The effective tax rate on the Lacerte Federal Tax Summary is incorrect because of the additional Child Tax Credit.  In prior years, the entire credit was up in the credit section.  Now it is in the payments section, so when the effective tax rate is calculated, it doesn't include the credits, which makes the comparative rates way off.  My clients pay attention to the number, so it is confusing.  I would suggest you calculate the effective rate after the refundable credits, to make the rate comparative to 2020.
