How much are IRS penalties?
There are many reasons why the IRS may assess interests and penalties on a tax return. In addition to interest, the tax laws provides various penalties for lack of tax law compliance. Some of these IRS penalties are:
Failure to file tax return IRS penalties
When a taxpayer fails to file his or her tax return by the tax due date (which is April 15 for most people or by the extension date if filed for an extension), a penalty of 5% per month up to a maximum of 25% is imposed on the amount of tax shown as due on the tax return. Any fraction of a month counts as a full month, just like most banks do.
Failure to pay taxes IRS penalties
If a taxpayer owes tax to the IRS but fails to pay when due as shown on the tax return, a failure to pay tax penalty is imposed in the amount of 0.5% per month up to a maximum of 25%. Any fraction of a month counts as a full month.
What are the IRS penalties for not filing tax return and not paying taxes due?
If a taxpayer neither files his or her tax return nor pay the taxes due to the IRS, then he or she will be assessed the penalties for both failure to file and failure to pay. For the month in which both the failure to file tax return penalty and the failure to pay tax penalty apply, the failure to file penalty is reduced by the amount of the failure to pay penalty.
