Get your taxes done using TurboTax

does the notice show the calculation of the penalty because we have no access to your reporting or the notice

 

the rules:

withholding and timely estimated tax payments must meet the lowest of either of the following

1) 90% of current year tax 

2) 100% of last year's tax. That jumps to 110% if your prior year adjusted gross income was over $150,000

 

also there is no penalty if you owe $1000 or less after subtracting withholding (estimates don't count) from 90% of the current year tax. 

 

not knowing how much is involved we don't know if requesting first time abatement is advisable.
