The Home-Office Mileage Rule: How a Home Office Makes Your First Business Drive Deductible (2026)

Published: June 28, 2026 · Reading time: 6 min

TL;DR: The first and last drives of your day are normally nondeductible commuting — unless your home is your principal place of business. A qualifying home office (used regularly and exclusively, and the place you run the business from) makes your business day start at home, so driving from there to a client or job site is business travel between two business locations, not commuting. The home office doesn't change the rate ($0.725/mile in 2026) — it changes which miles count. You still need a contemporaneous mileage log. Get both halves right and the daily driving most freelancers lose to commuting becomes deductible on Line 9.

Two freelancers drive the exact same route — home to a client, client to a supplier, supplier home — and one deducts every mile while the other can't deduct the first or last leg. The difference isn't the road. It's whether their home contains a qualifying home office. This is the single most overlooked lever in a freelancer's vehicle deduction, and it turns on a rule that's simpler than it sounds.

The Commuting Trap That Costs You the First Drive

Start with the rule the home office fixes. The IRS treats travel between your home and a regular place of business as commuting — personal, and nondeductible, regardless of distance. Only business miles — trips between business locations during your workday — go on Schedule C Line 9.

For a freelancer without a home office, "home" is just a residence. So the morning drive to your first client and the evening drive back are commuting, even though every stop in between is deductible. Over a year, that's a meaningful chunk of mileage quietly falling off your return.

How a Home Office Changes Your Starting Point

Here's the mechanism. If your home qualifies as your principal place of business, then your business day begins at that office. A drive from your home office to a client, job site, or supplier is no longer "home to work" — it's business location to business location, which is deductible business travel.

The destinations didn't move. Your tax home did. The same route that was partly commuting becomes fully deductible, because the trip now starts and ends at a place of business.

Scenario	First drive (home → client)	Middle drives	Last drive (client → home)
No home office	Commuting ❌	Business ✅	Commuting ❌
Qualifying home office	Business ✅	Business ✅	Business ✅

That two-cell swing — turning the first and last legs from ❌ to ✅ — is the entire value of the rule.

What Makes the Home Office "Qualifying"

The rule only works if the office genuinely qualifies — the same standard that supports the home-office deduction itself. Two tests, both required:

Regular and exclusive use. A defined space used only for business — not the kitchen table that becomes dinner, not the couch. A spare room or a dedicated corner works; a shared, dual-purpose space doesn't.
Principal place of business. It's where you conduct the administrative and management activities of the business — billing, scheduling, recordkeeping, client communication — and you have no other fixed location where you do that work.

Meet both, and the office anchors your mileage. Importantly, you can claim the mileage benefit of a qualifying home office even if you use the simplified method — or choose not to claim the home-office deduction — but the cleanest, most defensible position is to claim the home-office deduction on Form 8829 (or the simplified method) so the office is clearly established on your return.

You Still Need the Log

A qualifying home office gives you the legal right to the miles; a mileage log gives you the evidence. The IRS wants a contemporaneous record for each business trip:

Date, destination, business purpose, and miles for every trip
Odometer readings at the start and end of the year to fix total annual miles

A home office with no log is a right you can't prove. A perfect log with no qualifying home office still loses the first and last drives. You need both halves — and recording the trip as you go beats reconstructing it in April with round numbers, which is exactly what auditors flag.

The Temporary-Work-Location Exception (a Different Path)

If you don't have a home office, a narrower rule may still help: travel to a temporary work location can be deductible if you have a regular place of business elsewhere, or for assignments outside your metropolitan area. But it's more fact-dependent and easier to get wrong than the clean result a qualifying home office produces. For most freelancers who genuinely run the business from home, establishing the home office is the simplest, most durable way to make daily driving deductible.

Putting It Together for 2026

The playbook is short:

Set up a real home office — regular and exclusive use, your principal place of business.
Treat office-to-client drives as business miles, including the first and last legs.
Log every trip contemporaneously, with odometer photos on January 1 and December 31.
Deduct at $0.725/mile on Line 9 (or actual expenses if that wins), and keep the office records and the log together.

Capture both as you go — the office that makes the miles business and the log that documents them — and the commuting trap stops costing you the first drive of every workday. Pair it with organized receipts and quarterly estimates, and the vehicle deduction is fully built before tax season starts.

Frequently Asked Questions

Does a home office make my mileage deductible?

It can make a lot more of it deductible. Mileage is deductible when you drive between business locations, but the trip from home to your first work stop is normally nondeductible commuting. The exception: if your home qualifies as your principal place of business, your business day starts there — so driving from your home office to a client, job site, or meeting is travel between business locations, which is deductible. In effect, a qualifying home office erases the 'commuting' leg that otherwise costs freelancers the first and last drives of the day. The home office doesn't change the mileage rate ($0.725/mile in 2026); it changes which miles count as business.

What makes a home office 'qualifying' for the mileage rule?

Two things, and both must be true. First, regular and exclusive use: a specific area of your home used only for business, not a kitchen table that doubles as dinner space. Second, it must be your principal place of business — the place where you conduct the administrative or management activities of your business (billing, scheduling, recordkeeping, client communication) and have no other fixed location where you do that work. This is the same standard that supports the home-office deduction itself. If your home office meets it, it anchors your mileage too: the IRS treats trips from that office to other business locations as deductible business miles rather than commuting.

What's the difference between commuting and business miles for a freelancer?

Commuting is travel between your home and a regular place of business — it's personal and nondeductible, no matter how far. Business miles are trips between business locations during your workday: office to client, client to supplier, job to job. The reason the home-office rule matters so much is that it changes your starting point. Without a home office, your house is just 'home,' so the drive to your first stop is commuting. With a qualifying home office, your house contains your principal place of business, so that same drive is office-to-client business travel. The destinations didn't move; your tax home did.

Do I still need a mileage log if I have a home office?

Yes — the home office determines which miles qualify, but you still have to prove the miles. The IRS requires a contemporaneous record for each business trip: the date, the destination, the business purpose, and the miles driven, plus year-start and year-end odometer readings to establish total annual mileage. A qualifying home office without a mileage log gives you a strong legal position and no evidence; a great log without a qualifying home office still leaves your first and last drives as commuting. You need both halves: the office that makes the miles business, and the log that documents them.

Can I deduct the drive to a temporary work location without a home office?

Sometimes — there's a separate temporary-work-location rule, distinct from the home-office rule. If you have a regular place of business outside your home, travel to a temporary work location in the same trade or business is generally deductible. And if you have a regular work location away from home, you can deduct travel between home and a temporary location outside your metropolitan area. But these rules are narrower and more fact-dependent than the clean result a qualifying home office gives you. For most freelancers, establishing a legitimate home office as the principal place of business is the simplest, most defensible way to make daily business driving deductible.
