Although individual taxpayers may not deduct the value of their volunteering services, some expenses incurred while volunteering, for example, travel expenses are deductible if they are not reimbursed by the charity. The mileage rate for charitable deductions for the 2007 tax year is 14 cents per mile plus tolls and parking for non-Katrina related mileage. For Katrina relief efforts, you may deduct $0.32 or be reimbursed 44.5 cents [IR-2005-138] [see IRS code Sec 170(i)]. However, travel expenses are deductible only if there is no significant element of personal pleasure, recreation, or vacation associated with the travel and then limited to necessary lodging and meals while away from home overnight in rendering these services. For example, if you volunteered to help with a youth club campout, but visited friends along the way or spent time with your own family, you could not deduct these travel expenses.
