The IRS imposes the accuracy-related penalty due to a taxpayer’s underpayment of federal taxes through substantial understatement of income tax, negligence, or other errors in the tax return. The penalty is 20% of the underpayment. The main reason for implementing an accuracy-related penalty is to help the IRS enforce accurate payment and filing of annual tax returns.
Underpayment of Taxes
Before the IRS can impose an accuracy-related penalty against the taxpayer there must be an underpayment in taxes. The underpayment is related to one of the following instances:
- Disregard of rules or regulations or negligence;
- Any substantial understatement of income taxes;
- Any substantial valuation misstatement;
- Any substantial overstatement of pension liabilities;
- Any substantial estate tax or gift tax valuation understatement;
- Any disallowance of claimed tax benefits because of a transaction lacking economic substance;
- Any undisclosed foreign financial asset understatement; or
- Any inconsistent estate basis.
Defense Against Tax Underpayment Allegations
The accuracy-related penalty is not applicable if the taxpayer can show that the underpayment is due to a reasonable cause and that the taxpayer acted in good faith. Reasonable cause is considered on a case-to-case basis with a determinant factor as to what extent the taxpayer exerted effort to determine the proper tax liability. Other factors include the following:
- Experience, knowledge, and education of the taxpayer;
- The complexity of the law;
- The novelty of issue or the first impression to the courts;
- Whether there was no receipt of the third party’s information return/reliance;
- Adequate records;
- The credibility of the taxpayer; and
- Reliance on tax adviser advice.
Substantial-Authority Defense and Procedural Defense
Aside from the reasonable cause defense, the taxpayer can alternatively raise the substantial-authority defense and procedural defenses.
The substantial authority argument is difficult to prove. It requires corroborating code sections, regulations, revenue rulings and procedures, court cases, and other sources, which are treated as having authority to establish the taxpayer’s position.
As for the procedural argument, the IRS must show that the accuracy-related penalty is approved in writing by its examiner’s immediate supervisor. The IRS must do this no later than the issuance date of the notice of deficiency asserting the penalty. Failure of the IRS in proving the procedural burden will make the taxpayer avoid accuracy-related penalties.
For the imposition of the accuracy-related penalty, the Internal Revenue Code imposes the burden of proof on the IRS that the penalty is warranted. Suppose the taxpayers IRS defense lawyer can show credible evidence, correctly substantiate items, maintain records, and cooperate with reasonable IRS requests, then the IRS will have the burden of proof concerning the factual issues.
