The IRS Commuting Rule, Explained (2026)

It’s 6:47 a.m. A real estate agent walks out the door with a thermos and her tablet. She drives 14 miles to a 7 a.m. showing, then 9 miles to a listing appointment, then back home to take a lender call. Is the first drive deductible? The second? The drive home?

A DoorDash driver drops his daughter at school, then taps “Dash Now” in the school parking lot. He drives four miles toward a McDonald’s that the app pings him from. Was he commuting? Or working?

An Uber driver in Austin pulls out of her apartment, drives 12 miles to a hot zone downtown, sits for three minutes, goes online, and accepts a ride to the airport. The first 12 miles — those mean roughly $1,200 a year. Are they hers to deduct or not?

The answer comes from one Revenue Ruling: Rev. Rul. 99-7, 1999-1 C.B. 361. The IRS wrote it in 1999 after losing a Tax Court fight with a logger named Walker. The ruling sets out three safe harbors that decide when a drive between your house and a work location counts as deductible business mileage, and when it counts as a personal commute. This post walks through all three, explains the home-office override that changes the answer for most drivers, and shows how the rule lands for rideshare, delivery, real estate, and contractor drivers. The stakes for a full-time driver are usually a four-figure number every April.

Key takeaways

• The default is nondeductible. §262 and Treas. Reg. §1.262-1(b)(5) treat commuting between home and a work location as a personal expense.
• Rev. Rul. 99-7 carves out three safe harbors. (a) drives to a temporary work location outside your metropolitan area; (b) drives to a temporary work location in the same trade when you have a regular work location somewhere else; and (c) any business drive from home when home qualifies as your principal place of business under §280A(c)(1)(A).
• The home-office override is the unlock for most drivers. Under §280A(c)(1) as amended by Taxpayer Relief Act of 1997 §932, a home office used for administrative or management activities can be your principal place of business — and Curphey v. Commissioner, 73 T.C. 766 (1980), says that turns ordinary commutes into deductible business drives.
• “First business stop, last business stop” is the working rule when you don’t have a home office. Mileage starts when you reach (or “are at”) your first business location and stops when you leave the last one.
• §274(d) substantiation is strict. No contemporaneous log, no deduction. Cohan v. Commissioner, 39 F.2d 540 (2d Cir. 1930), doesn’t save you on car expenses, and Velez v. Commissioner shows that logs reconstructed before trial fail.

Why the rule exists: §262, the default, and what “commuting” means

The starting point is §262: personal, living, and family expenses aren’t deductible. Treas. Reg. §1.262-1(b)(5) calls out commuting by name — the taxpayer’s costs of commuting to a place of business or employment are personal expenses. That regulation, plus §262, is the rule the IRS uses to bounce thousands of mileage deductions every audit cycle.

The “ordinary and necessary” expense provision in §162(a) sits on the other side. Business travel between work locations is deductible. The fight in every commuting case is which bucket a particular drive falls into.

Why living far from work doesn’t help: the IRS treats where you live as a personal choice. Commissioner v. Flowers, 326 U.S. 465 (1946), settled that point. Distance doesn’t convert a commute into a business trip. Steinhort v. Commissioner, 335 F.2d 496 (5th Cir. 1964), made the flip side equally clear: once you’re moving between two business locations during the day, those miles are deductible.

The technical term for the location your travel is measured from is your “tax home.” Tax home and residence aren’t always the same thing. Hantzis v. Commissioner, 638 F.2d 248 (1st Cir. 1981), held that a Harvard law student with no business connection to Boston couldn’t treat Boston as her tax home for purposes of deducting summer-job expenses in New York. For a self-employed driver who works in the area where they live, the tax home and the residence are usually the same, and the practical question is which drives starting from that residence count as business.

Rev. Rul. 99-7’s three safe harbors

Rev. Rul. 99-7 states the general rule (commuting is personal) and then lists three exceptions. Read them as a ladder. If one applies, the drive is deductible.

Safe harbor (a) — Temporary work location outside your metropolitan area

A daily drive from home to a temporary work location outside the metropolitan area where you live and normally work is deductible. “Temporary” under Rev. Rul. 99-7 means the work is realistically expected to last — and actually lasts — one year or less. Work expected to last more than a year isn’t temporary, even if it ends early.

Translation for drivers: if you live and work in greater Phoenix and drive to a one-day job in Flagstaff, that drive can qualify. A daily drive to a job in Mesa probably won’t.

Safe harbor (b) — Temporary work location, with a regular location elsewhere

If you have at least one regular work location away from your residence, you can deduct drives between home and a temporary work location in the same trade or business, regardless of distance. The temporary work site can be inside the metropolitan area. The catch is that you need a true regular work location — not just your house.

For drivers, this safe harbor matters most for real estate agents with a brokerage desk they actually use, and contractors with a yard or shop they report to. It’s the weakest safe harbor for rideshare and delivery drivers because most have no fixed regular work location at all.

Safe harbor (c) — Home is the principal place of business

If your residence is your principal place of business under §280A(c)(1)(A), drives between home and any other work location in the same trade are deductible. It doesn’t matter whether the other location is regular or temporary. It doesn’t matter how far. This is the safe harbor that does the most work for self-employed drivers, and it’s the subject of the next section.

What counts as a “metropolitan area”?

Rev. Rul. 99-7 never defines “metropolitan area,” and neither does the Code. In Bogue v. Commissioner, T.C. Memo. 2011-164, aff’d, 522 F. App’x 169 (3d Cir. 2013), the Tax Court said outright that “the term ‘metropolitan area’ is ill defined, and we therefore consider the facts and circumstances in deciding whether particular commuting expenses were incurred in traveling to a worksite unusually distant from the area where the taxpayer lives and normally works.” Bogue’s five construction sites in 2005 and 2006 — most across the state line in Pennsylvania — were all within 20.1 miles of his New Jersey home. He lost. In Saunders v. Commissioner, T.C. Memo. 2012-200, a Valley Interior Systems drywall worker living in Manchester, Ohio, drove to five temporary worksites 74 to 96 miles from his home. He also lost — in part because he testified on the stand that his “main area” was the “Cincinnati metropolitan area,” and the court took him at his word.

A few practical rules follow:

• Inside roughly 30 miles of home is almost always inside your metro.
• 100+ miles out, in a different commuting region, is usually outside your metro.
• Between 30 and 100 miles is a facts-and-circumstances fight, and you carry the burden under Tax Court Rule 142(a) and Welch v. Helvering, 290 U.S. 111 (1933).
• Use U.S. Census Metropolitan Statistical Area boundaries as evidence, not as law. They’re persuasive, not binding.

The cleaner play for self-employed drivers is to qualify under safe harbor (c) — get a home office — and stop arguing about metropolitan boundaries.

The home-office override (§280A) and the post-1997 fix

This is where the rule changes shape for drivers who set up their business correctly.

In 1993, the Supreme Court decided Commissioner v. Soliman, 506 U.S. 168. Dr. Soliman was an anesthesiologist who saw patients at three hospitals and did all of his administrative work — billing, recordkeeping, scheduling — from a dedicated room in his Virginia condominium. The Court said the home office wasn’t his “principal place of business” because the most important functions of his practice (treating patients) happened at the hospitals. Hundreds of thousands of self-employed taxpayers lost their home-office deductions overnight.

Congress reacted four years later. Taxpayer Relief Act of 1997 §932 added flush language to §280A(c)(1) that overrode Soliman for tax years beginning after December 31, 1998. The statute now reads, in relevant part, that the term “principal place of business” includes a place of business used by the taxpayer for the administrative or management activities of any trade or business of the taxpayer if there is no other fixed location of that trade or business where the taxpayer conducts substantial administrative or management activities.

That language is the unlock. A home office qualifies as the principal place of business if two conditions are met:

1. Exclusive and regular use. A specific part of the home is used only for business and used on a regular basis.
2. Administrative-activities safe harbor. The taxpayer performs administrative or management activities at the home office, and there is no other fixed location where substantial administrative or management activities happen.

Once that home office qualifies, Curphey v. Commissioner, 73 T.C. 766 (1980), supplies the transportation rule. The Tax Court wrote: “We see no reason why the rule that local transportation expenses incurred in travel between one business location and another are deductible should not be equally applicable where the taxpayer’s principal place of business with respect to the activities involved is his residence.” Rev. Rul. 99-7’s third safe harbor codifies that holding.

In plain English: if your home qualifies under §280A(c)(1)(A), your drive from the kitchen table to a showing, a pickup, or a hot zone isn’t a commute. It’s a business drive.

How this looks for each driving persona

Rideshare drivers (Uber, Lyft)

Without a §280A home office, the daily pattern is clean and painful. The drive from home to the hot zone is commuting. The miles you log going online — what Uber calls Period 1 (P1, waiting), Period 2 (P2, en route to rider), and Period 3 (P3, on trip) — are business. The drive home at the end of the shift is commuting again. Uber’s 1099-K and tax summary only report on-trip miles. P1 and P2 are yours to log — see our Rideshare Driver Mileage Tax Guide 2026.

With a §280A home office (you do scheduling, bookkeeping, expense tracking, and platform admin from a dedicated desk at home, with no other fixed location for those activities), every drive from home to anywhere business-related is deductible under Rev. Rul. 99-7(c). The hot-zone deadhead becomes business mileage.

Delivery drivers (DoorDash, Uber Eats, Instacart, Walmart Spark, Amazon Flex)

Same pattern. Multi-app drivers usually go online before leaving the driveway. If you’ve activated DoorDash before you back out, you’re in P1-equivalent status: available and looking for work. The conservative position without a home office is to start counting business miles from your first accepted offer (or first pickup) and stop at your last drop-off. The aggressive position is “online means working.” The IRS has never blessed it for delivery, and Saunders-style audits aren’t kind to it. See our Delivery Driver Mileage Tax Guide 2026 for the multi-platform mechanics.

With a home office: every drive from home to a pickup, between pickups, and back home is deductible.

Real estate agents

Almost every active agent qualifies under §280A(c)(1)(A) if they want to. Listing prep, CMA work, MLS searches, client emails, transaction coordination — these are textbook administrative activities. The “no other fixed location” prong is satisfied if your brokerage doesn’t give you a private desk you actually use for administrative work. Many brokerages provide a shared hot desk and a conference room, which is generally not enough to count as a fixed administrative location for the agent personally. See our Mileage Tracking for Real Estate Agents guide for the home-office election mechanics.

Once the home office qualifies, every drive from home to a showing, a listing appointment, a closing, a sign installation, and back to home is deductible. The Curphey rule does the work.

Contractors and couriers between job sites

Steinhort settles the easy half: drives between job sites during the day are deductible. The home-to-first-site drive is the question. With a home office that satisfies §280A(c)(1)(A) — and many sole-prop contractors do their estimating, invoicing, and scheduling from a dedicated home office — the first and last drives become business mileage too.

The Walker case — why Rev. Rul. 99-7 exists

The story is short, and worth telling.

Charles Walker was a self-employed logger who lived in Hill City, South Dakota. He drove from his home to cutting sites in the Black Hills National Forest that ranged from 18 to 60 miles away, working roughly two to three weeks at each site before moving on. He kept his tools at the house and did about seven hours a week of maintenance and call-taking there. The IRS allowed his between-job-site drives and disallowed the home-to-site drives as commuting.

In Walker v. Commissioner, 101 T.C. 537 (1993), the Tax Court sided with Walker. It held that under the IRS’s then-current ruling (Rev. Rul. 90-23), Walker’s home was a “regular place of business” — separate from the §280A “principal place of business” question — and his drives to temporary logging sites were therefore deductible. The court explicitly rejected the IRS’s argument that the §280A standard should govern transportation deductions.

The IRS nonacquiesced. Then, in 1994, it issued Rev. Rul. 94-47, which formally said the Service “will not follow the decision in Walker v. Commissioner.” In 1999, the IRS replaced 94-47 with Rev. Rul. 99-7 — the rule we still use today. The 99-7 ruling kept Walker’s outcome (deductibility) but narrowed it. Now you get the deduction if the work location is temporary and outside your metropolitan area, OR if you have a regular work location away from home, OR if your home is your principal place of business under §280A. The Tax Court’s “regular place of business” theory from Walker is gone.

Walker won. The IRS responded by writing a Revenue Ruling specifically to overrule him.

Substantiation — §274(d) and the Velez cautionary tale

You can be technically right about every safe harbor and still lose at audit. §274(d) imposes “strict substantiation” for vehicle expenses, which Treas. Reg. §1.274-5T spells out. You need contemporaneous records of date, mileage, destination, and business purpose for each trip.

The Cohan rule — Cohan v. Commissioner, 39 F.2d 540 (2d Cir. 1930) — lets courts estimate some business expenses when records are imperfect. It does not apply to vehicle expenses. §274(d) specifically overrides Cohan for listed property, which includes passenger automobiles under §280F(d)(4).

Reconstructed logs don’t work. In Velez v. Commissioner, T.C. Memo. 2018-46, an Ohio tax attorney with five offices lost his entire $29,693 vehicle deduction because he created his mileage logs two days before trial, from iPad calendar entries and credit card statements. The court applied §274(d) strictly and sustained a 20% accuracy-related penalty under §6662.

The §280A home-office election is itself a fact you have to prove. Photograph the office. Keep a floor plan with square footage. Save calendar entries for admin work performed there. The IRS examiners who look at vehicle expenses also look at the home-office filing on Form 8829, and they look at both together. Our Mileage Audit Defense Playbook covers the response-letter mechanics if you ever receive a Form 4564 IDR on this topic.

Worked example A — Rideshare, no home office

Maria drives for Uber and Lyft in Austin. She works from her car. She does no scheduling or bookkeeping from a dedicated home office. Her residence doesn’t qualify under §280A(c)(1)(A).

Her daily pattern: 8 miles from home to a downtown hot zone, online for six hours of P1/P2/P3 driving totaling 140 miles, then 8 miles home at the end of the shift.

• Home → hot zone (8 mi): nondeductible commute. Not outside her metro (safe harbor (a) fails); no regular work location away from home (safe harbor (b) fails); no §280A office (safe harbor (c) fails).
• P1/P2/P3 miles (140 mi): deductible business mileage under §162(a). She’s moving between fares for business reasons.
• Hot zone → home (8 mi): nondeductible commute.

Annual cost of the deadhead miles: 16 miles per day × 220 driving days = 3,520 nondeductible commute miles. At the 2026 rate of 72.5¢ per mile under Notice 2026-10 (up 2.5¢ from the 2025 rate of 70¢), that’s $2,552 in deductions Maria never gets to claim. A defensible home-office position — if she had one — would recapture all of it.

Worked example B — Real estate agent, with §280A home office

David is a real estate agent in Charlotte. He has a dedicated 80-square-foot home office where he runs CMAs, manages his MLS account, drafts offers, runs client communications, and does his bookkeeping. His brokerage gives him access to a shared hot desk but no private workspace and no fixed administrative location. He photographs the office, documents the square footage, and elects the home-office treatment on Form 8829.

His Tuesday: home → 9:30 a.m. showing (18 mi) → 11 a.m. second showing (7 mi) → lunch with a referral partner (4 mi) → brokerage to drop a check (12 mi) → 3 p.m. closing (9 mi) → home (15 mi). Total: 65 miles.

Under Rev. Rul. 99-7(c), every leg is deductible because his home is his principal place of business under §280A(c)(1)(A) flush language. The 18-mile first leg and the 15-mile last leg — the two drives that would have been commuting without the home office — are now business miles.

Annual recapture: 33 “would have been commuting” miles per working day × roughly 220 working days = 7,260 miles. At 72.5¢, that’s $5,264 in newly deductible drives David can claim because of how he set up his business — not because he drove any extra miles.

The IRS Commuting Rule is one of the few tax rules where a $40 piece of furniture (a desk) and a couple of hours of paperwork (a real home-office setup and a properly filed Form 8829) can move thousands of dollars of mileage from the personal column to the business column. Rev. Rul. 99-7 is short — six pages — and the structure is simple. Read it, decide which safe harbor fits you, build the file that proves it, and log every drive. The 47 examples in our business-mile guide and the Schedule C NAICS code guide cover the rest of the Line 9 filing path.

Frequently asked questions

Is my drive from home to my first delivery deductible?

Only if (a) your home is your §280A principal place of business, (b) the first delivery point is a temporary work location outside your metropolitan area, or (c) you have a regular work location away from your residence and the delivery point is a temporary location in the same trade. Without one of those, the first drive is a commute under Rev. Rul. 99-7.

What counts as a 'temporary' work location?

Under Rev. Rul. 99-7, a work location where the work is realistically expected to last — and actually lasts — one year or less. If the work is expected to last more than a year, it's not temporary, even if it ends early.

How do I prove my home office qualifies under §280A?

Show exclusive and regular use of a defined area for business. Show that you perform administrative or management activities there. Show that you have no other fixed location where substantial administrative or management activities occur. File Form 8829. Keep dated photographs, a floor plan with square footage, and calendar entries that reflect the admin work performed in the office.

What's the 'metropolitan area' for commuting purposes?

There is no statutory definition. Bogue v. Commissioner calls the term 'ill defined' and applies a facts-and-circumstances test. Census MSAs are a useful starting point. The burden to prove a worksite is outside your metro area is on you.

Can I deduct the drive home after my last delivery?

If your home is your §280A principal place of business, yes. Otherwise, no — the drive from your last business stop back home is a commute, just like the drive in the morning.

Does the commuting rule treat W-2 employees the same way?

For self-employed Schedule C drivers, the rules above apply in full. W-2 employees lost the unreimbursed-employee-expense deduction when the Tax Cuts and Jobs Act suspended it through §67(g) in 2018, and §70110 of the One Big Beautiful Bill Act (Pub. L. No. 119-21, signed July 4, 2025) made that suspension permanent. Notice 2026-10 confirms the standard mileage rate cannot be used to claim an itemized deduction for unreimbursed employee travel.

I drive for both Uber and DoorDash — does the rule apply differently?

The rule applies to your trade or business, not to each platform. The IRS generally treats rideshare and delivery driving as a single 'for-hire driving' trade or business for purposes of §162. Drives between gigs on different platforms are business drives. Drives between home and your first gig on any platform are governed by Rev. Rul. 99-7 the same way.

Are tolls and parking deductible if the underlying drive is commuting?

No. Tolls and parking follow the character of the drive. If the drive is a personal commute under §262, the tolls and parking are personal too.

What if I forgot to log some drives — can I reconstruct?

You can try, but §274(d) requires contemporaneous substantiation for vehicle expenses, and Cohan v. Commissioner doesn't apply to listed property. Velez v. Commissioner is the cautionary tale: a sophisticated taxpayer with five offices lost his entire vehicle deduction because he built his logs two days before trial. Reconstructed logs occasionally survive when paired with strong corroborating evidence (Google Maps history, calendar entries, photos), but they're a weak hand. The cure is to log going forward.
