Mileage for Volunteer Board Service at a Professional Association: Business Rate, 14-Cent Charity Rate, or Nothing (2026)

Published: November 2, 2026 · Reading time: 12 min

TL;DR: Unpaid board service feels like charity, but the charity mileage rate (14 cents) works only for a qualified organization. Publication 526 lists "chambers of commerce and other business leagues or organizations" among organizations that aren't qualified, and many professional associations are business leagues under section 501(c)(6). So a board trip for that kind of association is a business trip or nothing. It can be business only if it is ordinary and necessary for your business and it passes the commuting rules. A trip for the association's separate 501(c)(3) foundation may be a 14-cent charity mile on Schedule A. Value business trips at 72.5 cents (January 1 to June 30, 2026) or 76 cents (from July 1). Never claim one trip both ways, and confirm each category with a CPA or EA.

Why Board Service Gets Misfiled

Many freelancers sit, unpaid, on the board of a state chapter of their professional association, a local guild or a regional trade group, and drive to its meetings. At tax time, some file those miles as charity because the job is unpaid. Others file them at 72.5 or 76 cents because the group is about their profession. Each instinct is half right, and the answer turns on two separate questions:

1. What kind of organization is it? Only a qualified organization can receive deductible contributions, including volunteer car costs.
2. Is the trip connected to your own business? That takes an ordinary-and-necessary connection and a trip that is not a commute.

For how the four mileage rates compare in general, see business vs. charity, medical and moving mileage rates.

Question 1: Is the Organization Qualified to Receive Deductible Contributions?

Professional associations are often business leagues

Section 501(c)(6) of the Code covers:

"Business leagues, chambers of commerce, real-estate boards, boards of trade, or professional football leagues (whether or not administering a pension fund for football players), not organized for profit and no part of the net earnings of which inures to the benefit of any private shareholder or individual."

A business league is tax-exempt, but that does not make it a charity. Publication 526 (the 2025 edition, which the IRS page shows as last reviewed April 30, 2026) says, under "Contributions to Nonqualified Organizations":

"You can't deduct contributions to organizations that aren't qualified to receive tax-deductible contributions, including the following."

The list that follows includes "Chambers of commerce and other business leagues or organizations." It also names certain state bar associations that have private as well as public purposes.

Why that closes off the charity rate

Publication 526 ties volunteer car costs to the kind of organization you serve:

"Although you can't deduct the value of your services given to a qualified organization, you may be able to deduct some amounts you pay in giving services to a qualified organization. The amounts must be: Unreimbursed; Directly connected with the services; Expenses you had only because of the services you gave; and Not personal, living, or family expenses."

If your association is a business league, driving to its board meetings is not "giving services to a qualified organization," so the 14-cent rate is not available for those trips. Publication 463's introduction points volunteers the same way, to "a qualified charity."

Some professional groups are charities, and many associations have a foundation

Do not assume the answer from the group's name. Some professional societies are section 501(c)(3) charities, and many business leagues run a separate foundation, often for scholarships or research, that may be a qualified organization even though the association is not. Publication 526 tells you how to check:

"You can ask any organization whether it is a qualified organization, and most will be able to tell you. You can also check by going to IRS.gov/TEOS ."

Ask for the exact legal name and status of the entity whose board you sit on. If you serve on both the association and its foundation, treat them as two organizations with two sets of trips. (Dues follow their own rules; see trade association dues and the lobbying portion.)

Question 2: Is the Trip Connected to Your Own Business?

The ordinary-and-necessary test

Section 162(a) of the Code allows a deduction for "all the ordinary and necessary expenses paid or incurred during the taxable year in carrying on any trade or business." Publication 334 explains the two words:

"An ordinary expense is one that is common and accepted in your field of business. A necessary expense is one that is helpful and appropriate for your business. An expense does not have to be indispensable to be considered necessary."

Publication 334's list of local transportation expenses includes:

"Visiting clients or customers. Going to a business meeting away from your regular workplace."

A board meeting of the association in your field can fit that, but it is not guaranteed to. None of Publication 334, Publication 463 or Publication 526 mentions association board service by name, so no IRS sentence settles it. The question is whether the trip is part of carrying on your business. It helps if the association is in the field your Schedule C income comes from and the role brings referrals or knowledge you use with clients. It hurts if the group is unrelated to your trade or the role is a personal interest. If unsure, ask a CPA or EA.

The commuting rules still apply

Passing that test does not turn a commute into a business trip. Publication 334 says:

"You can't deduct the costs of driving your car or truck between your home and your main or regular workplace. These costs are personal commuting expenses."

Where the trip starts matters:

• From a qualifying home office. Publication 463 says: "If you have an office in your home that qualifies as a principal place of business, you can deduct your daily transportation costs between your home and another work location in the same trade or business." See the home office mileage rule.
• From a rented office or studio. Office to meeting can be local transportation; home to office is still a commute.
• With no regular place of work. Publication 463 says: "You can't deduct daily transportation costs between your home and temporary work sites within your metropolitan area. These are nondeductible commuting expenses." See temporary work locations and commuting vs. business miles.

The Charity Side: When the Foundation Is the Organization

If you serve a qualified organization, such as a 501(c)(3) foundation, the charitable rules apply. Section 170(i) of the Code says:

"For purposes of computing the deduction under this section for use of a passenger automobile, the standard mileage rate shall be 14 cents per mile."

The IRS rates page shows 14 cents in both halves of 2026. Publication 526 adds:

"If you don't want to deduct your actual expenses, you can use a standard mileage rate of 14 cents a mile to figure your contribution. You can deduct parking fees and tolls whether you use your actual expenses or the standard mileage rate."

Its volunteer table, asked about a volunteer office 30 miles from home, answers: "Yes, you can deduct the costs of gas and oil that are directly related to getting to and from the place where you volunteer. If you don't want to figure your actual costs, you can deduct 14 cents for each mile."

Where it goes, and when it helps

Publication 526 says to enter "your cash contributions, including out-of-pocket expenses, on Schedule A (Form 1040), line 11." Charity miles do not reduce Schedule C profit or self-employment tax, and they help only if you itemize (standard vs. itemized). Two changes from Public Law 119-21 apply to taxable years beginning after December 31, 2025:

• The 0.5% floor. Section 170(b)(1)(I) says a charitable contribution otherwise allowable "shall be allowed only to the extent that the aggregate of such contributions exceeds 0.5 percent of the taxpayer's contribution base for the taxable year." Contribution base is generally adjusted gross income, and the non-itemizer rule below is figured without regard to this floor.
• The non-itemizer deduction. Section 170(p) lets someone who does not itemize deduct up to $1,000 ($2,000 on a joint return), but it counts only "contributions made in cash" to certain organizations. We found no IRS source saying volunteer mileage counts, so do not assume it does; see the non-itemizer guide and ask a CPA or EA.

What you cannot deduct

Publication 526 says you can't deduct the value of your time or services, including "The value of income lost while you work as an unpaid volunteer for a qualified organization." It also lists, under personal expenses, "The cost of meals you eat while you perform services for a qualified organization, unless it is necessary for you to be away from home overnight while performing the services." Reimbursed amounts are not deductible. See charitable donations for freelancers.

Side by Side

If the association reimburses mileage, see mileage reimbursement vs. deduction and ask a CPA or EA.

Worked Example: One Freelancer, Two Boards

Priya is a freelance bookkeeper filing Schedule C. For this example, her home office qualifies as her principal place of business, which is what lets trips from home be business trips. She serves on two boards in 2026:

• The state chapter of a bookkeepers' association. The chapter confirms it is a section 501(c)(6) business league. Its members are her referral network, and she and her preparer conclude the meetings are ordinary and necessary for her business. Meetings are 18 miles each way, a 36-mile round trip.
• The chapter's scholarship foundation. It confirms it is a section 501(c)(3) charity. She drives to its review meetings, a 24-mile round trip, as an unpaid volunteer.

Neither group reimburses her. Figures are computed per period and rounded to the cent.

She attends five association meetings in each half of the year (5 × 36 = 180 miles per half) and two foundation meetings in each half (2 × 24 = 48 miles per half), and pays $10 of parking at two foundation meetings.

The association trips come to $267.30 on Schedule C ($130.50 + $136.80). Because that reduces net profit, it also reduces self-employment tax by about $267.30 × 0.9235 × 0.153 = $37.77; the income tax effect depends on the rest of her return, so this guide does not estimate it. The foundation trips come to $33.44 ($13.44 + $20.00), a Schedule A item.

Two things the totals do not show:

• The $33.44 may be worth nothing. It counts only if Priya itemizes. Even then, if her contribution base were $70,000, the 0.5% floor would be $350, so her charity miles help only as part of total charitable gifts above that amount.
• Swapping the labels would be wrong in both directions. Booking the 96 foundation miles at the business rate would claim 48 × $0.725 + 48 × $0.76 = $71.28 on Schedule C for trips that are volunteer service, not her business. Booking the 360 association miles at 14 cents, $50.40, would claim a charitable deduction for an organization Publication 526 lists as nonqualified.

If her home office did not qualify, the association figure would need a fresh look under the commuting rules and could fall to zero. The foundation figure would not change, since Publication 526 allows the trip to and from the place where you volunteer.

How to Log Board Trips

Publication 526 says car records "may be considered reliable if you made them regularly and at or near the time you had the expenses." Each board trip should carry:

• Date, so each business trip gets the right 2026 rate
• Organization's legal name, so association and foundation trips stay apart
• Start, end and miles, plus the purpose and category (business, charity or personal)
• Any reimbursement

Publication 526 adds that unreimbursed out-of-pocket expenses for a qualified organization, "considered separately, of $250 or more," need adequate records and an acknowledgment from the organization; one round trip rarely reaches that, but a convention flight can. On a day with a board meeting and client visits, log each leg with its own purpose (multi-stop days); a personal detour can cap the deduction at the direct route (personal errands). See also contemporaneous log requirements.

Common Mistakes

1. Claiming 14 cents for a business league. The charity rate needs a qualified organization.
2. Assuming unpaid means charity. The organization's status is the test.
3. Assuming the profession link makes every trip business. It must also be ordinary and necessary, and not a commute.
4. Mixing the association and its foundation. Two entities can have two answers.
5. Claiming both rates for one trip. One trip, one purpose.
6. Using one 2026 business rate. Value each business trip at 72.5 or 76 cents by its date.
7. Deducting your time. Publication 526 says you can't deduct the value of your time or services.

How CentSense Helps

• Scan parking receipts, meeting invoices and conference registrations with AI the day you pay. The free tier includes 10 AI scans a month
• On the Solo plan ($5/month), log trips by date with a destination and purpose, and get unlimited scans and CSV export. Write the organization's legal name in each trip's notes so association and foundation trips stay apart. CentSense's mileage export applies a single annual business rate and does not apply the July 1, 2026 split (72.5 cents, then 76 cents) to each trip, so value each business trip at the rate for its date
• Hand your CPA or EA a CSV of individual trips and receipts

CentSense stores and organizes records. It does not decide whether an organization is qualified, whether a board trip is ordinary and necessary for your business, or whether a trip is commuting. Those are judgments for you and your CPA or EA.

Frequently Asked Questions

Can I deduct mileage to a professional association board meeting at the 14-cent charity rate?

Only if the organization is a qualified organization, and many professional and trade associations are not. Publication 526 says you can't deduct contributions to organizations that aren't qualified to receive tax-deductible contributions, and its list includes chambers of commerce and other business leagues or organizations. Many professional associations are business leagues under section 501(c)(6). Check the group's status with the organization or at IRS.gov/TEOS, and ask a CPA or EA before you claim any charity miles.

Can a freelancer deduct association board mileage as a business expense instead?

Possibly. Publication 334 lists going to a business meeting away from your regular workplace as a local transportation expense, and the expense must be ordinary and necessary for your business. Publication 334, Publication 463 and Publication 526 do not address association board service by name, so the trip has to be connected to your trade or business on its own facts. The commuting rules still apply: a trip from home is deductible only if, for example, your home office qualifies as your principal place of business. Confirm with a CPA or EA.

What mileage rate applies to association board trips in 2026?

If a trip is a deductible business trip, the IRS standard business rate is 72.5 cents per mile from January 1 through June 30, 2026 (IR-2025-128) and 76 cents per mile from July 1 through December 31 (IR-2026-29), so value each trip at the rate for its date. In this guide's example, 180 miles in each half come to $130.50 and $136.80, or $267.30, assuming a qualifying home office and a real business connection. Parking and tolls are added separately. A CPA or EA can confirm which trips qualify.

What if I serve on the association's charitable foundation instead?

A foundation that is a qualified organization, such as a section 501(c)(3) charity, is a different case. Publication 526 says you can deduct unreimbursed out-of-pocket costs such as gas and oil (not depreciation, insurance or repairs) directly related to giving services to a charitable organization, or use 14 cents a mile, plus parking and tolls. The deduction goes on Schedule A, so it helps only if you itemize, and from 2026 itemized charitable gifts count only above 0.5% of your contribution base. Confirm the foundation's status and your treatment with a CPA or EA.

Can I deduct the same board trip as both business and charity mileage?

No. Each trip, or each leg of a trip, is driven for one purpose and gets one treatment. If a trip to a board meeting is a deductible business trip, it goes on Schedule C at the business rate for its date; if it is volunteer service for a qualified charity, it goes on Schedule A at 14 cents. If neither test is met, it is personal. Record the purpose at the time of the trip, not at tax time, and ask a CPA or EA how to treat a leg that is genuinely unclear.

Can I deduct the value of my time spent on a nonprofit board?

No. Publication 526 says you can't deduct the value of your time or services, including the value of income lost while you work as an unpaid volunteer for a qualified organization. What you may be able to deduct are unreimbursed out-of-pocket costs directly connected with the services, such as car expenses, and only if the organization is qualified. A professional association that is not a qualified organization does not change this. Ask a CPA or EA about your facts.

What records do I need for board meeting mileage?

For each trip, log the date, the organization, the destination, the miles and the purpose, and whether the organization reimbursed you. Publication 526 says that with the 14-cent rate your records must show the miles you drove for the charitable purpose, and a separate rule requires an acknowledgment from the organization when unreimbursed out-of-pocket expenses, considered separately, are $250 or more. Business trips need the same date, destination, purpose and miles. Keep meeting notices too, and review the log with a CPA or EA.
