Director, Exam Policy
This IRM contains information specific to interest computations for all areas of the Service. Instructions for processing cases/adjustments unique to a business operating division can be found in the applicable IRM for the specific business function(s).
The Servicewide Interest Program is now the Office of Servicewide Interest (OSI).
The IRS administers the internal revenue laws, including laws that govern the computation and payment of interest.
This multi-functional IRM provides instructions for computing interest and applies to all functional areas, business operating divisions, Appeals, Taxpayer Advocate Service, and Criminal Investigation.
Policy statements that relate to interest are found in the IRM 1.2.20, Policy Statements for Penalties and Interest Activities.
This section provides administrative guidelines.
In accordance with IRC 6601(a), IRC 6601(b), and IRC 6611, the payment of interest is required unless otherwise specified by law.
IRC 6601(a) states that if any amount of tax, "Is not paid on or before the last date prescribed for payment, interest on such amount at the underpayment rate established under section 6621 shall be paid for the period from such last date to the date paid."
IRC 6601(b) provides that an extension of time to file or any installment agreement under IRC 6159 does not extend the time to pay.
IRC 6611(a) states, "Interest shall be allowed and paid upon any overpayment in respect of any internal revenue tax at the overpayment rate established under section 6621."
IRC 6621 provides the interest rates on overpayments and underpayments of tax, which are tied to the federal short-term interest rate.
While the above paragraphs deal mostly with "normal interest" computations, information on "restricted interest" and other complex interest computations can be found in later sections of IRM 20.2, Interest. The types of interest are defined in IRM 126.96.36.199, Terminology.
Campus directors are authorized to perform all administrative actions on all interest cases/adjustments including restricted interest conditions, except those:
Involving suits for refund filed by taxpayers in which a credit (overpayment) is determined by a court, or
Requiring review by the Joint Committee on Internal Revenue Taxation.
Interest is statutory. Interest cannot be reduced or abated due to reasonable cause. It also cannot be negotiated. See IRM 20.2.7, Abatement and Suspension of Interest: IRC 6404 and 7508, for reasons interest can be reduced or abated.
All reference materials involving interest must be consistent with the procedures in this IRM and must be approved by management in SB/SE, Examination, Exam Policy, Office of Servicewide Interest (SE:S:E:EP:OSI).
To maintain the accuracy of IRM 20.2, Interest, send corrections, change requests, and inquiries to the Office of Servicewide Interest (OSI) via the Servicewide Electronic Research Program (SERP) Feedback System. The SERP Staff submits the SERP feedback requests to the appropriate IRM author for consideration. This process of submitting feedback to the OSI is easy to use and provides continuous tracking that allows viewing the status of any feedback inquiries. SERP feedback issue reporting can be used to address concerns with IRMs posted on SERP. Follow guidelines contained in IRM 188.8.131.52.2, IRM 21 - Change Requests, to submit feedback issues.
Before you submit questions regarding interpretation of IRM instructions via the SERP feedback form, please consult your lead or manager for assistance.
When it is necessary to seek Chief Counsel advice on an interest issue, the request needs to be shared with the OSI as it is being forwarded to Chief Counsel. The request may also be sent through the OSI for submission of the request to Chief Counsel. This action ensures the OSI staff stays abreast of emerging issues that impact interest computation and provide for distribution of that information to all area offices and campuses.
Employee suggestions should continue to be sent through the Employee Suggestion Program for consideration.
Other methods that may be used to contact the Office of Servicewide Interest are shown below.
Report Programming Problems: Use Form 5715, Systems Production Evaluation Report, (also in electronic version) to report systemic programming and operational problems that need immediate attention (work stoppage situations only). See IRM 3.0.273.3.3, Form 5715, Systems Production Evaluation Report.
Ask an Analyst: Questions are entered on the Office of Servicewide Interest website http://sbseservicewide.web.irs.gov/interest/default.aspx. Responses are posted to the website as well as to the individual who asked the question. Basic requests on how to compute interest must not be submitted to the site. If the question asked is taxpayer or tax module specific, it will be edited so that it may be viewed on the website by a wider audience.
Use the Penalty and Interest Notice and Explanation (PINEX), or a legible print from Command Code (CC) COMPAD, INTSTD or the Automated Computation Tool (ACT/DMI) 490 Report to provide a taxpayer a calculation of credit or debit interest related to a tax module. See IRC 6631 and IRM 184.108.40.206, Manual Computations. See also IRM 20.2.3, Command Code PINEX, for PINEX instructions and IRM 20.2.2, Methods of Computing Interest. Remove the taxpayer's SSN, except for the last four digits, prior to mailing any correspondence per OMB Memorandum M-07-16, Safeguarding Against and Responding to the Breach of Personally Indentifiable Information.
If And Then
a taxpayer inquires about computer generated interest by telephone,
you are unable to match the interest on their notice by using CC INTSTD, COMPAD, or ACT,
prepare Form 4442Inquiry Referral, (paper or electronic versions) and send to an interest specialist within your campus.
a taxpayer inquires about manual computation of interest,
you are unable to match the interest assessed,
obtain the original source document that outlines how the interest was computed. Verify it and provide a copy of this information to the taxpayer, or send to a Field Office Resource Team (FORT) manager at the Memphis or Ogden Campus.
The website link is: http://sbse.web.irs.gov/CCP/Exam/Exam.htm.
If, during a taxpayer contact, it appears the taxpayer may meet Taxpayer Advocate Service (TAS) criteria (see IRM 220.127.116.11, TAS Case Criteria, and you are unable to resolve the issue within 24 hours, you may refer the taxpayer to TAS. If it is not a hardship case, do not refer the taxpayer to TAS unless the taxpayer requests to be transferred to TAS and meets the criteria.
When you refer cases to TAS, complete Form 911, Request for Taxpayer Advocate Service Assistance (and Application for Taxpayer Assistance Order), and forward to TAS.
The terminology used in this handbook is described in Exhibit 20.2.1-2.
The statutory requirements for calculating interest on underpayments and overpayments are contained in IRC 6601 and IRC 6611, respectively. The payment of interest on underpayments and overpayments under these provisions is mandatory unless specifically prohibited by law.
The two types of interest are:
Credit Interest (overpayment) - Interest paid to the taxpayer by the IRS on an overpayment of any internal revenue tax, and
Debit Interest (underpayment) - Interest charged to the taxpayer when tax, penalty, addition to tax, or interest is owed to the government.
Different interest rates may apply to underpayments and overpayments. See IRC 6621. After December 31, 1998, the interest rates for non-corporate taxpayers became equal for both underpayments and overpayments, while they are still different for corporate taxpayers.
The term "simple interest" refers to interest that is computed only on the principal amount owed. Simple interest accrued on overpayments and underpayments of tax and penalties before January 1, 1983. At that time, the government was prohibited from computing interest on interest (compounding interest).
The term "compound interest" refers to interest that accrues on both the principal amount and on any interest charged on the principal (i.e., interest on interest).
The IRS is required to compound interest daily, effective January 1, 1983.
When it is necessary to manually compute interest, use Command Code (CC) COMPA or the Automated Computational Tool (ACT/DMI).
The term "normal interest" refers to interest that is computed without regard to any restrictions.
On an underpayment, normal interest is computed from the date the liability is due to the date the liability is fully paid, taking into account any payments, credits, and suspensions.
On an overpayment, normal interest is computed from the availability date of the overpayment to the date provided by IRC 6611(b), depending on whether the amount is credited (offset) or refunded.
Generally, it is not necessary to manually compute and adjust normal interest. Master File programming will compute normal interest based on debits and credits posted to the tax module.
The term "restricted interest" refers to any interest that is manually computed because the IRS computer is unable to identify all conditions necessary to make an accurate interest computation.
Restricted interest is subject to the same three variables (time, rate, and amount) as computer generated interest. However, the rules that govern restricted interest are more complex than those for normal interest; the variables of time and rate may differ.
In many instances, Master File programming cannot compute restricted interest. Therefore, you must manually compute and adjust interest when Master File limitations prevent systemic generation of interest. See IRM 20.2.8, Restricted Interest.
The term "annual interest netting" refers to a method of computing interest which equalizes the difference between credit and debit interest rates within a single tax module on the same amount during overlapping periods. For example, if a taxpayer received a refund with interest and it is later determined that an underpayment exists in that module during the same time period, the debit and credit interest rates will be "netted or equalized" within that tax module during the overlapping period. If there is no reason to otherwise manually compute and restrict interest, then it is not necessary to manually compute interest to make an annual netting adjustment. See IRM 20.2.14, Netting of Overpayment and Underpayment Interest.
The term "Net Rate Interest Netting" refers to the method of computing interest to equalize/eliminate the interest rate differential between overpayments and underpayments (for the same taxpayer for the same or different types of tax). The overlapping debit and credit interest computation periods occur between different tax modules on equivalent amounts. See IRM 20.2.14, Netting of Overpayment and Underpayment Interest, for instructions on making net rate interest netting adjustments.
Modules requiring net rate interest adjustments are always restricted from systemic computation and require a manual calculation of interest. Since IDRS interest computation command codes are not suited to perform net rate calculations, use the Automated Computational Tool (ACT/DMI).
Interest rates for tax overpayments and underpayments are established under IRC 6621. The interest rates are determined quarterly.
The normal overpayment and underpayment interest rate is three percentage points above the federal short-term rate. The corporate credit interest rate is one percent less than the normal debit interest rate, while the General Agreement on Tariffs and Trade (GATT) rate is an additional one and half percent below the corporate credit interest rate. The large corporate underpayment rate (LCU) is two percent more than the normal underpayment interest rate. See Exhibit 20.2.1-2, for the explanation of these terms.
This section explains the due dates of various types of tax returns. See Exhibit 20.2.1-3 for return due dates.
When a due date falls on a Saturday, Sunday, or legal holiday, the return will be considered timely filed if it is filed on the next succeeding day that is not a Saturday, Sunday, or legal holiday. See IRC 7503.
This rule does not change the actual due date of the return. However, the application of IRC 7503 may relieve the taxpayer of the liability for late filing and payment penalties.
The term "legal holiday" means a legal holiday in the District of Columbia and, in the case of an act required to be performed in any office of the Internal Revenue Service located outside the District of Columbia, a statewide holiday in the state where such office is located. Holidays that fall on a Saturday are observed the previous Friday and those that fall on a Sunday are observed the following Monday.
Statewide legal holidays and legal holidays in the District of Columbia are:
January 1 - New Year's Day
Third Monday in January - Martin Luther King Jr. Day
January 20 - Inauguration Day (every fourth year following a Presidential election) in the District of Columbia and certain counties in Maryland and Virginia
Third Monday in February - Washington's Birthday (also known as President's Day)
April 16 - Emancipation Day in the District of Columbia
Last Monday in May - Memorial Day
July 4 - Independence Day
First Monday in September - Labor Day
Second Monday in October - Columbus Day
November 11 - Veterans Day
Fourth Thursday in November - Thanksgiving Day
December 25 - Christmas Day
Certain statewide legal holidays (e.g., Patriot's Day - third Monday in April for those filing at the Andover Campus).
See IRM 18.104.22.168.18, List of Legal Holidays.
If a federal holiday is declared by the President or Congress due to the death of a former president, a return filed by the next business day will be considered timely. The following are considered federal holidays:
April 27, 1994 - Former President Richard M. Nixon.
June 11, 2004 - Former President Ronald W. Reagan.
January 2, 2007 - Former President Gerald R. Ford.
