Save a PDF with all the worksheets to see form 2210 calculation but if you owe more than $1000 then a penalty can be applied. If you qualify for an exception then you can avoid the penalty ... the program uses the most common one automatically ... the most common is to pay in 100% of last year's tax liability so if you look at the 2017 tax liability and the 2018 taxes paid you will most likely see that the 2018 amount is at least the 2017 amount but the same cannot be said for the 2018/2019 situation ... but a $2 penalty is almost nothing.
