The current IRS 1040 tax table is available on IRS.gov, the official website of the Internal Revenue Service, the IRS reports. Under Forms and Pubs, choose Tax Table to view the 1040 tax table.
Subsequently, you can order tax forms and publications by mail to receive a paper copy of the 1040 tax table, explains the IRS.
To use the tax table to determine tax liability, you must determine your filing status, then cross-reference your status with your taxable income as reported on Form 1040, TurboTax explains. Tax tables are set up by columns, with one column for filing status and rows of the various taxable income. Taxpayers can find their tax liability for the year where the filing status meets the taxable income.
