If you didn’t pay enough tax throughout the year, either through withholding or by making estimated tax payments, you may have to pay a penalty for underpayment of estimated tax. Generally, most taxpayers will avoid this penalty if they owe less than $1,000 in tax after subtracting their withholdings and credits, or if they paid at least 90% of the tax for the current year, or 100% of the tax shown on the return for the prior year, whichever is smaller. There are special rules for farmers, fishermen, and certain higher income taxpayers. Please refer to Publication 505, Tax Withholding and Estimated Tax, for additional information.
怎么听着不太对劲儿，真的可以把“estimate of total tax”空着吗？

多谢大家！
“ That doesn't sound right, are you sure?", 这样是不是有点侮辱别人？
，但我不做税了，这个可以，只是个延期表，在4月15前交了你2021估计的欠税可以了
谢谢！

安全的数额是上交上年税的110%，这样没有penalty, 如果2021的实际税高于你预缴的税款，那你付利息就可以了，那个表4.5.6 填不填都无所谓，最重要的要把7填上，数额=(110% 上年的税额-2021已交的税），把钱交给在4月15日前交给irs
