Interest and Penalties(p85)

rule
You do not have to figure the amount of any interest or penalties you may owe. Because figuring these amounts can be complicated, we will do it for you if you want. We will send you a bill for any amount due.
If you include interest or penalties (other than the estimated tax penalty) with your payment, identify and enter the amount in the bottom margin of Form 1040A, page 2. Do not include interest or penalties (other than the estimated tax penalty) in the amount you owe on line 45.

Interest(p85)

rule
We will charge you interest on taxes not paid by their due date, even if an extension of time to file is granted. We will also charge you interest on penalties imposed for failure to file, negligence, fraud, substantial valuation misstatements, substantial understatements of tax, and reportable transaction understatements. Interest is charged on the penalty from the due date of the return (including extensions).

Late filing.(p85)
rule
If you do not file your return by the due date (including extensions), the penalty is usually 5% of the amount due for each month or part of a month your return is late, unless you have a reasonable explanation. If you do, include it with your return. The penalty can be as much as 25% of the tax due. The penalty is 15% per month, up to a maximum of 75%, if the failure to file is fraudulent. If your return is more than 60 days late, the minimum penalty will be $135 or the amount of any tax you owe, whichever is smaller.

Late payment of tax.(p85)
rule
If you pay your taxes late, the penalty is usually 1/2 of 1% of the unpaid amount for each month or part of a month the tax is not paid. The penalty can be as much as 25% of the unpaid amount. It applies to any unpaid tax on the return. This penalty is in addition to interest charges on late payments.

Frivolous return.(p85)
rule
In addition to any other penalties, the law imposes a penalty of $5,000 for filing a frivolous return. A frivolous return is one that does not contain information needed to figure the correct tax or shows a substantially incorrect tax because you take a frivolous position or desire to delay or interfere with the tax laws. This includes altering or striking out the preprinted language above the space where you sign. For a list of positions identified as frivolous, see Notice 2010-33, 2010-17 I.R.B. 609, available at
www.irs.gov/irb/2010-17_IRB/ar13.html.

Other.(p85)
rule
Other penalties can be imposed for negligence, substantial understatement of tax, reportable transaction understatements, filing an erroneous refund claim, and fraud. Criminal penalties may be imposed for willful failure to file, tax evasion, or making a false statement, or identity theft. See Pub. 17 for details on some of these penalties.
