IRS Issues Guidance on 2013 Standard Mileage Rates

Part III -- Administrative, Procedural, and Miscellaneous

SECTION 1. PURPOSE

This notice provides the optional 2013 standard mileage rates for taxpayers to use in computing the deductible costs of operating an automobile for business, charitable, medical, or moving expense purposes. This notice also provides the amount taxpayers must use in calculating reductions to basis for depreciation taken under the business standard mileage rate, and the maximum standard automobile cost that may be used in computing the allowance under a fixed and variable rate (FAVR) plan.

SECTION 2. BACKGROUND

Rev. Proc. 2010-51, 2010-51 I.R.B. 883, provides rules for computing the deductible costs of operating an automobile for business, charitable, medical, or moving expense purposes, and for substantiating, under § 274(d) of the Internal Revenue Code and § 1.274-5 of the Income Tax Regulations, the amount of ordinary and necessary business expenses of local transportation or travel away from home. Taxpayers using the standard mileage rates must comply with Rev. Proc. 2010-51. However, a taxpayer is not required to use the substantiation methods described in Rev. Proc. 2010-51, but instead may substantiate using actual allowable expense amounts if the taxpayer maintains adequate records or other sufficient evidence.

An independent contractor conducts an annual study for the Internal Revenue Service of the fixed and variable costs of operating an automobile to determine the standard mileage rates for business, medical, and moving use reflected in this notice. The standard mileage rate for charitable use is set by § 170(i).

SECTION 2. STANDARD MILEAGE RATES

The standard mileage rate for transportation or travel expenses is 56.5 cents per mile for all miles of business use (business standard mileage rate). See section 4 of Rev. Proc. 2010-51.

The standard mileage rate is 14 cents per mile for use of an automobile in rendering gratuitous services to a charitable organization under § 170. See section 5 of Rev. Proc. 2010-51.

The standard mileage rate is 24 cents per mile for use of an automobile (1) for medical care described in § 213, or (2) as part of a move for which the expenses are deductible under § 217. See section 5 of Rev. Proc. 2010-51.

SECTION 3. BASIS REDUCTION AMOUNT

For automobiles a taxpayer uses for business purposes, the portion of the business standard mileage rate treated as depreciation is 21 cents per mile for 2009, 23 cents per mile for 2010, 22 cents per mile for 2011, 23 cents per mile for 2012, and 23 cents per mile for 2013. See section 4.04 of Rev. Proc. 2010-51.

SECTION 4. MAXIMUM STANDARD AUTOMOBILE COST

For purposes of computing the allowance under a FAVR plan, the standard automobile cost may not exceed $28,100 for automobiles (excluding trucks and vans) or $29,900 for trucks and vans. See section 6.02(6) of Rev. Proc. 2010-51.

SECTION 5. EFFECTIVE DATE

This notice is effective for (1) deductible transportation expenses paid or incurred on or after January 1, 2013, and (2) mileage allowances or reimbursements paid to an employee or to a charitable volunteer (a) on or after January 1, 2013, and (b) for transportation expenses the employee or charitable volunteer pays or incurs on or after January 1, 2013.
