Please remember that IRS is a pay-as-you-go system - you must pay income tax as you earn or receive the income during the year. So for 2019...you will avoid the penalty if you either owe less than $1000 in tax or if you paid your withholding/estimated tax of at least 90% of the tax for the current year (which will be your 2019 year) or 100% of the tax shown on your 2018 tax year(whichever is smaller).
