There are two types of tax penalties: filing late and paying late. IRS penalties only apply when you owe taxes; if you are owed a refund or do not owe any taxes, there is no penalty for filing late. File your returns as soon as possible if you owe taxes. At the very least, file or e-file a tax extension to reduce the late filing penalty, as it is significantly higher than the late payment penalty. The penalty for not doing your taxes is typically around 5% of the tax you owe, increasing by 5% each month until reaching a maximum failure to file penalty of 25%. e-File your taxes in the year they are due so you never have to worry about accruing late penalties or filling out paper forms.
Important: The IRS has waived most late filing penalties for 2019, 2020 tax returns.
