Important efile.com Deadline Tax Tip: The penalties for not filing are higher than not paying taxes, thus don’t miss a filing deadline if you owe taxes, even if you can’t pay your taxes on time, since the late filing penalties are generally significantly higher than the not paying taxes on time penalties. Efile and pay as little or as much as you can afford. Use the PENALTYucator tool to find out your potential penalties.
