Changes to Certain Calculations of the Taxable Benefit of the Non-Business
Use of State-Provided Vehicles, Calendar Year 2008


When a state employee commutes in or uses a state vehicle for personal business, certain tax consequences result. The Internal Revenue Service views the personal use as a taxable benefit to the employee and has established guidelines on how to determine how much the dollar value of that benefit would be.

This memorandum supersedes Memorandum 2007-02 and advises agencies of a change in the rate used in the vehicle cents-per-mile method and advises agencies and employees of a change in the definition of control employee (yearly compensation).


Effective January 1, 1986, Federal Public Law 99-44 mandates that an employee's personal use of an employer-owned or leased vehicle must be reported to the Internal Revenue Service (IRS) as taxable income. Personal use is defined as any non-business use, including commuting from an employee's home to his or her worksite. The term - vehicle - means any motorized wheeled vehicle manufactured primarily for use on public streets, roads and highways and generally includes automobiles. Except for certain exceptions as set forth later in this memorandum, all State of Connecticut employees will be subject to taxation on any state vehicle use which is not documented as business use. State agencies will be responsible for implementing the applicable reporting requirements.

The following IRS requirements and other guidelines are set forth to assist agencies in determining those employees whose use of state vehicles is deemed taxable and in reporting the dollar value, by employee, of such benefits.


As stated by the three branches of government, the policy of the State of Connecticut basically prohibits personal use of state-owned/leased vehicles except for home-to-worksite travel as required by the employer. Under the State of Connecticut's written policy, no employee may use the vehicle for personal purposes other than de minimis use (e.g., a stop for lunch between two business appointments or deliveries). Refer to the Department of Administrative Services General Letter No. 115 dated November 1997.


The following methods are to be used in valuing the taxable benefit:

A. Commuting Value Method - for use by a non-control employee only (defined in Section V).
Personal commutation to work is valued at a daily commuting rate of $1.50 for each one-way trip (or $3.00 round trip).

B.Fleet Average Value Method - A monthly rate of $131.40 per 30-day month plus 5.5 cents per mile for gasoline is assessed; or a per diem rate of $17.53.

NOTE: If the vehicle is used more than seven days in a month, it is advantageous to use the monthly rate rather than the per diem rate.

C. Annual Lease Value Method - This method must be used for any vehicle that exceeds the $19,900 value (per IRS Reg. 1.61-21(d)(5)(v)). Agencies will be contacted if a fleet vehicle exceeds the stated value. All other agencies who purchase vehicles must use this method in accordance with the IRS Publication 15-B. The vehicles' fair market value (FMV) will determine the monthly rate, plus 5.5 cents per mile for gasoline.

NOTE: Once computed, the Annual Lease Value remains in effect until 12/31 of the 4th full calendar year after the rule is first applied.

D.Vehicle Cents-Per-Mile - Personal miles are valued at 50.5 cents per mile effective January 1, 2008. If the employer does not supply gasoline, the rate is reduced by 5.5 cents to 45 cents per mile. Cents-per-mile valuation rule cannot be used for vehicles with FMV exceeding $15,400 (per IRS Reg 1.61-21(e)(1)(iii)(B)). Note: Amount is revised annually.

NOTE: Special rules may apply when using each of these methods. Once one of the valuation methods is elected, the employee must use it for all subsequent years unless the qualification rules are not met.


To calculate the value of his or her commuting or personal miles an employee would:

A. Select the Appropriate Method

Control employees can choose only the lease value or the cents-per-mile methods for calculation of the taxable benefit.

A control employee is defined as:

a. an elected official; or
an employee whose annual compensation will equal or exceed $139,600 in 2008.

All other employees must use the commuting value method.

B.Perform the Calculation

Example 1:Commuting Value Method (used by all non-control employees)

The employee commuted round trips to work for 60 days during the reporting quarter. The rate of $3.00/day is multiplied by 60 days = $180.00.

Example 2:Control Employee Using Fleet Lease Value or Cents-Per-Mile

The employee has been assigned a state vehicle for the first time. She commutes 20 miles to work round trip for 60 days in the quarterly reporting period. She may choose one method of valuing the use of the vehicle. A comparison of the methods follows:

$131.40/month for 3 months

= $394.20

20 miles/day at 5.5 cents/mile

multiplied by 60 days

= $ 66.00


= $460.20

20 miles/day at 50.5 cents/mile by 60 days


In this example the lease value method is the least costly. However, once a method is selected, the employee must continue with that method despite any changes in his or her circumstances.

Example 3: Control Employee Using Annual Lease Value

The control employee has been assigned a vehicle for the first time. The vehicle was purchased by his agency and has a Fair Market Value (FMV) of $20,100. He commutes 20 miles to work round trip for 60 days in the quarterly reporting period.

1. Determine the FMV of vehicle when made available;

2. Use table in IRS Reg. 1.61-21(d)(iii) or Pub. 15-B to compute Annual Lease Value ;

3. Value the fuel (if provided) at 5.5 cents per mile;

4. Determine the monthly rate (ALV/365 (days per yr) x 30 (days per month).

$460.27/month for 3 months = $1380.81
20 miles/day at 5.5 cents/mile by 60 days = $ 66.00


The cents-per-mile valuation rule cannot be used for vehicles with a FMV exceeding the rate established per IRS Reg. 1.61-21(d)(5)(v).

Note: When performing the calculation for any method for any vehicle that is not part of the DAS on-line reporting program, net out any amount that has been paid to the state as reimbursement for personal use. (If the amount paid the state exceeds the taxable benefit for the tax year, the benefit equals zero. Credit amounts cannot be carried forward.)

VI. EXCEPTIONS (Applicable to Eligible Control and Non-Control Employees)

The following categories of vehicle use are not presently subject to taxation:

1. Qualified Non-Personal Use Vehicles

The term - qualified non-personal use vehicle - is applied to any vehicle that, because of its nature, is not likely to be used more than a very limited (i.e., de minimis) amount for personal purposes.

Refer to Attachment A for a listing of - qualified non-personal use - vehicles that fall within this exception with explanatory information concerning the exception requirements for vans and trucks and the narrowly-defined requirements for law enforcement officer.

2.Overnight Parking (Garaging) of Vehicle at Approved State-Owned or Leased Facility

Taxation will not apply if an employee uses an approved state-owned or leased facility for the overnight garaging of an assigned state vehicle even though such facility was some distance from the employee's worksite and possibly close to his or her home. However, this exception is qualified by three stipulations: (a) a vehicle usage and parking location must make good business sense to the employer; (b) overnight parking location must be approved by the employer; and (c) if the driver transports one or more passengers from their home(s) to the worksite, such passengers are subject to taxation on the derived benefits.

3.De Minimis Use of Vehicle

According to Section 1.132-6 of the IRS Regulations, the term - de minimis fringe - means any property or service, the value of which is (after taking into account the frequency with which similar fringes are provided by the employer to the employer's employees) so small as to make accounting for it unreasonable or administratively impracticable.

The regulations give as an example of fringe benefit that is not excludable from gross income: the commuting use of an employer-provided automobile more than one day a month. The regulations also say that "the fact that the commuting use of an employer-provided vehicle more than one day a month is an example of a benefit not excludable as a de minimis fringe does not mean that the commuting use of a vehicle up to 12 times per year is excludable from gross income as de minimis fringe.


Vehicle Usage Fringe Benefit Computation Records

1.The Vehicle Usage Fringe Benefit Computation Records are:

Computation Record for Lease Value Method (Form CO-961);
Computation Record for Cents-Per-Mile Method (Form CO-960); and
Computation Record for Special Commuting Rate (Form CO-959).

2. From the information on the Monthly Usage Report (Form CCP-40), the agency will then post data as needed to the Employee's Computation Record.

3.Follow instructions on the Computation Record to calculate the monthly value of the fringe benefit.

4. Submit the required paperwork to his or her business office for inclusion in a payroll transaction.

5. Retain the Computation Record and the documenting CCP-40 for the later of
(a) three years or (b) until examination by the Auditors of Public Accounts.

The Department of Administrative Services (DAS) has implemented a program with select officials where they report their state vehicle usage on-line. Questions regarding this procedure should be directed to DAS, Fleet Operations.


Agencies are to notify concerned employees of the preceding requirements and the definition of control employee, lease value rate and cents-per-mile valuation rate.

Agencies must continue to maintain the records necessary to properly determine and report on the dollar value of the vehicle use benefit for the period November 1, 2007 through October 31, 2008.
