Thanks. I'm glad mine was nice and simple. If it got very complex, I'd give it a try but then use a CPA to compare and learn. Strangely 1040.com reversed their 69.90 charge (which seemed like it was too high based on my return anyway) so now it looks like I filed for free. I got my refunds already so I know it all went through okay but the charge reversal was an oddity.
I tried doing 2018 back of the napkin style and with the increase in child tax credit, it looks like I owe $0 (and may get some back for refundable credits).
Using an estimated salary number:
$60,000 of W2 income + taxable interest
Minus
$24,000 of std deduction for MFJ
Equals
$36,000
Tax burden of $36,000 = $3,939
Two $2,000 child tax credits plus a $200 Savers credit = $4,200
The child tax credits are refundable up to $1400(not sure if per child or total) but the Savers credit is not.
Assuming I change nothing, would I get refunded the $261 difference or only $61 since the savers credit is part of the equation?
