General tax education, not tax advice. A phone used for gig apps is an ordinary business expense when the facts support it. It is not inside the standard mileage rate, and it is not automatically 100% because a Driver app is installed. Confirm Publication 463, Publication 535, and the Schedule C instructions for the year you file. Have a tax professional review family plans, employer-reimbursed lines, and any claim that a mixed-use iPhone is exclusively business.
You already take 72.5¢ or 76¢ for the car. The useful question is not “what else can I throw at Line 9?” It is what still costs money to run the business after the rate has paid for the car. Offers, navigation, and platform messages run on a phone. That bill is not gas. It is not insurance. It is not inside the cents-per-mile figure.
The hype version of this article says deduct the whole family plan because DoorDash is on one line. That is usually wrong. The honest version — business-use percentage, dedicated vs. shared, how to split an itemized bill, which accessories stack, what not to claim at 100%, and where the dollars typically land on Schedule C — is below. The longer extras list is write-offs that stack with the mileage deduction. The car lines themselves are in how to claim car expenses on Schedule C.
The short version: keep standard mileage for the car. Add the business percentage of the phone and data you actually use for the apps. A second work-only phone can support a high percentage; a shared iPhone cannot be 100% because TikTok lives there too. Split a family plan down to your line first, then apply the percentage. Mounts and chargers used for the work can stack. Do not claim the whole household bill, and do not multiply any of this by 72.5¢ or 76¢.
Step 1: Confirm phone and data sit outside the mileage rate
The 2026 standard mileage rates — 72.5¢ for business miles driven January 1 through June 30 and 76¢ from July 1 through December 31 — stand in for ordinary car costs: gas, oil, repairs, tires, insurance, registration, and depreciation. Publication 463 still lets certain extras sit on top of that bundle. A phone is one of them because it is not a cost of pointing the car down the road. It is a cost of running the gig.
| Item | Inside 72.5¢ / 76¢? | Still deductible separately? |
|---|---|---|
| Gas, oil, tires, repairs, car insurance | Yes | No — that would be both methods on one car |
| Phone service and data used for the apps | No | Yes, business-use % |
| Mount, charger, cigarette-socket cable, power bank used for work | No | Yes, if ordinary and necessary |
| Business parking and tolls | No | Yes, if unreimbursed — different article |
| Personal Netflix, iCloud for family photos, a spouse’s line | No | No |
Do not multiply a $90 Verizon bill by 76¢. Receipts stay receipts. Miles stay miles. If you chose actual expenses instead of the rate, the phone still works the same way — it was never a car operating cost. What changes is only the car method. That fork is standard mileage vs. actual expenses.
Step 2: Measure business-use percentage for a dedicated or shared phone
The deduction is not “the phone.” It is the business share of the phone. Two common setups:
Dedicated work phone
A second device used only for Uber, Lyft, DoorDash, Instacart, Spark, Amazon Flex, Grubhub, or whatever you actually drive can support a high percentage. “High” is not a slogan for 100% if you also text friends from it, stream music for personal trips, or hand it to a kid. Exclusive business use is a fact. If it is true, keep it true: no personal Apple ID purchases, no personal photos as the main camera, no personal hotspot for the house. A cheap prepaid line used only in the cup holder is the clean version of this story.
Shared / only phone
Most drivers have one phone. Offers, Google Maps, personal texts, Instagram, and the school calendar share the same radios. Installing a Driver app does not convert the line. You need a reasonable business-use percentage — time the device is used for the gig versus everything else, or a data split if the bill or a settings screen actually shows one. A sample week of notes (hours online, hours of personal use) beats a round 80% invented in April. Revisit the percentage if winter volume collapses or if you take a month off.
Illustration only, not a promise: a $70/month unlimited line used about half for offers, navigation, and platform chat is about $35/month before you add a mount. Twelve months at that split is $420. That is not $70 × 12 claimed in full, and it is not $70 × 76¢.
Step 3: Allocate the bill with an itemized method you can show
Keep the PDFs or screenshots. A deduction without a bill is a number. Examiners can add. Your method should survive a short conversation.
| What the bill looks like | Usual approach |
|---|---|
| One line, your name, itemized taxes and fees | Business % × (monthly service + the taxes/fees that attach to that service). Skip add-ons that are personal (extra cloud, a streaming bundle, device insurance you would keep anyway if you quit driving). |
| Family or multi-line plan | Take your line’s share of talk/text/data and a reasonable slice of shared account charges, then apply business %. Do not deduct kids’ lines or a spouse’s personal phone because one Driver app exists in the household. |
| Employer or platform reimbursement | Deduct only what you still paid. If someone already covered the line, that dollar is not yours twice. |
| Prepaid refill used only in the car | The refill is the receipt. Still apply business % if the same SIM is also personal hotspot at home. |
| Handset / installment on the same bill | The phone hardware is equipment, not the data plan. Business % of a device you also use to live your life is not 100%. Large equipment may need depreciation or a section 179 analysis — that is a preparer question, not a blog percentage. |
Home Wi-Fi is a cousin, not the same line. If you schedule, upload logs, and answer support email from a qualifying workspace, a business slice of internet can be a separate utilities question. Streaming movies on that Wi-Fi is personal. Do not fold the household fiber bill into “data plan” because the phone hops on it at night.
Which miles the phone was navigating still have to be classified honestly. A personal grocery loop with the app open is still personal driving; that split is what counts as a business mile. The phone percentage and the mile classification are related stories. They should not contradict each other.
Step 4: Add ordinary supplies that stack and skip what does not
Accessories used to run the apps in the car are usually supplies: a vent or dash mount, a charging cable that actually feeds the work phone, a cigarette-socket adapter, a power bank you carry for long airport sits. Ordinary and necessary. Keep the receipt. A $25 mount is $25, not $25 × 76¢.
What not to claim at 100% (or at all)
- 100% of a family plan because one line runs DoorDash.
- 100% of the only phone you own when it is also personal texts, social, banking, and photos.
- A spouse’s or kid’s line that never takes an offer.
- Streaming bundles, extra iCloud, and game passes parked on the same bill.
- A new car stereo, a personal iPad, or AirPods you wear to the gym. Work headphones you actually use for platform calls are a closer (still documented) fact.
- Gas, insurance, or a second copy of the same miles sitting next to the phone line. Those are the mileage-method mistakes in the stacking guide.
- A reimbursed line deducted again.
Platform-specific phone habits do not change the percentage math. Flex itineraries, Spark offers, Grubhub contribution screens, and Uber pings all run on the same kind of device. The platform guides — DoorDash, Uber & Lyft, Amazon Flex, Instacart, Grubhub, Spark Driver — are about income and which miles count. This page is the bill in your email.
Step 5: Place phone, data, and supplies on the typical Schedule C lines
Line numbers move if the IRS redesigns the form. On the current Schedule C they typically land here:
| What you are claiming | Typical home |
|---|---|
| Standard mileage (first half × 72.5¢ + second half × 76¢) | Line 9 — Car and truck expenses |
| Unreimbursed business parking and tolls | Usually with Line 9 or as travel — dollars, not cents |
| Phone / data (business %) | Utilities (often Line 25) or Other expenses (Line 27a) labeled “cell phone” — not Line 9 |
| Mount, charger, cable, power bank | Supplies (often Line 22) or other expenses |
| Handset / expensive device (business %) | Supplies if small; otherwise depreciation / Form 4562 / section 179 — ask a pro |
| Business / commuting / other miles | Part IV (or Form 4562 Part V) |
Part IV still wants the mile split even if you add a phone bill. The log habit that makes Line 9 checkable is the same five fields as always. Phone receipts do not replace total annual miles. How those car numbers are supposed to look is Schedule C car expenses for gig drivers.
Self-employment tax is 15.3% on 92.35% of net profit. A real phone percentage lowers that profit. A made-up 100% does not stay cheap if it gets pulled. Neighboring 1099 mechanics are in self-employment tax for gig drivers.
The phone bill attaches to a dated mile log
I use the iPhone app TaxMiles: Mileage Tracker to auto-detect trips and classify them the same day so 72.5¢ / 76¢ attach to real dates. Keep the carrier PDF in the same folder as the export; the log is what the phone percentage has to be consistent with. Not MileIQ. Not Everlance. Not Mileage Tracker for Taxes (id 6758426140). Free plan is 40 trips a month; Pro is $5.99/month, $39.99/year, or $79.99 lifetime.

Can I deduct my phone if I already take the standard mileage rate?
The business percentage can. It is not a car cost and it is not inside 72.5¢ or 76¢. Gas still cannot sit on top of the rate. See write-offs that stack with mileage.
Can I claim 100% of my cell phone as a gig driver?
Only if the device is truly work-only. One phone that is also your life is a percentage. A family plan is a percentage of your line, not the household total.
How do I calculate business-use percentage for a data plan?
Use a method you can explain: time, or itemized data if the bill shows it. A sample week of notes is better than a round number at filing. Apply that fraction to your line, not to every line on the account.
Where does a phone bill go on Schedule C?
Not Line 9. Utilities or other expenses for the service; supplies or other expenses for a mount and charger. Confirm the current car-expense map so Line 9 stays miles (and parking/tolls), not phones.
Does the July 1, 2026 rate change affect my phone deduction?
No. 72.5¢ through June 30 and 76¢ from July 1 apply to business miles. Phone dollars stay dollars. The rate split is in the July 1 increase guide.
