According to my reviewed 2018 return, I have $0 tax on Taxable Income of $54000, married filing jointly. According to the 2018 tax tables, tax should be ~$6100. Why?

Did you have any Qualified Dividends and Capital Gains on your return? They are taxed at 0%, 15%, or 20% tax rate depending on your income. The Qualified Dividends and Capital Gain Tax Worksheet is used to calculate the tax if you have Qualified dividends or Capital gains on your return.
