Mileage, earnings and tax tracker for Spark drivers

What Solo does for Spark Drivers

Solo is the mileage, earnings and tax app for Spark, powered by Sherpa, the first AI assistant built for gig workers. Link your account once and Solo logs your business miles by GPS — including the drive to the store, between deliveries and back home — tracks your payouts next to every other app you work for, and projects and files your federal and state taxes.

Mileage, classified automatically

Solo matches each completed Spark delivery to the drive it already logged and files those miles as business. No start button.

Track every app in one app

Walmart Spark next to DoorDash next to Shipt, so one screen shows what your week actually paid and what gets deducted.

Taxes projected year-round, then filed

You see what you owe in July, and Annual Pro and Pro Plus members file federal and state from inside the app.

Automatic mileage tracking and classification starts on the Basic plan, $96 a year. For manual mileage tracking, no subscription plan is required. It’s also worth mentioning that the cost of Solo is 100% tax-deductible as a work expense — be sure to classify it as such.

Does Walmart Spark track your miles?

Not really. And the miles it doesn't count are usually the bigger number.

Spark Driver shows you the estimated distance of a batch before you accept it — store to customer, roughly. That estimate helps you decide whether to swipe, but it isn't a mileage log and it isn't what the IRS wants.

What it leaves out: the drive from your house to the store, the drive between stores when you're stacking batches, repositioning to a busier zone when orders slow down, and the drive home at the end of the night. For most shoppers, the miles Instacart never mentions are larger than the ones it does.

Why Spark’s batch distance isn't IRS-proof

Spark Driver shows a rough delivery-leg distance, not a contemporaneous mileage log. The IRS expects dates, distances, destinations and business purpose, recorded as you drive rather than reconstructed from batch summaries months later. A screenshot of your batch screen is not built to satisfy that standard.

These scenarios are uncommon and most shoppers will not get audited for mileage alone. The ones who do, and who can't produce a proper log, could lose their deductions.

How Solo tracks your Spark mileage automatically

Solo logs your drives in the background and matches them to your completed batches.

You link your Spark account once. Solo's GPS logs your trips as you drive, all of them, including the ones between deliveries. When you complete a batch on Spark Driver, Solo matches that batch against the drive it already recorded and files those miles as business.

No start button to remember. No swipe-left-for-personal queue waiting for you on Sunday night. No weekly review to catch the trips you forgot to classify.

That last part is where most mileage apps lose shoppers. An app that needs you to tap start before every store run will eventually miss a shift, which means more missed deductions and less money in your pocket.

Setting it up

1
Download Solo and link your Spark account.
2
Start your 7-day free trial on any plan.
3
Turn on mileage tracking and grant location access. Keep the app open in the background.
4
Drive. Solo logs your trips, then files the miles around each completed job as business.

Two minutes, and you don't touch it again.

Keeping personal trips out of it

Solo classifies the miles around your Spark batches as business and leaves the rest alone. The grocery run for your own fridge and the school pickup stay out of your deduction.

If you'd rather control it yourself, Solo has a manual mode you can switch on any time. Most shoppers prefer to have their miles automatically tracked and categorized, but if you want to use manual tracking at any point, it's only a quick toggle flip away.

Track Spark earnings alongside every other app

You pick up a Spark order in the morning, snag a DoorDash delivery over the dinner rush, and fill gaps with Shipt when the deliveries dry up. Three apps, three payout screens, three sets of numbers that never add up to one answer about your week.

Solo links them all: Spark, DoorDash, Shipt, Uber Eats, Grubhub, Amazon Flex, Instacart, and more. Link your accounts and see your earnings, miles, and expenses tracked in one place. Solo works as a Spark expense tracker too, so tolls, parking, and insulated bags sit next to the mileage they belong to as part of your tracked expenses.

Know what an hour pays before you commit

Smart Schedule predicts what an hour will earn before you decide to work it. Shoppers using it can earn up to 40% more per hour on average.

In most major metros, you can also lock the rate in from your Smart Schedule. Pay Guarantee fixes an hourly floor for a scheduled shift: work the hour, and if you earn less than Solo predicted, Solo pays the difference.

Ask Sherpa

Sherpa is Solo's AI assistant, and it answers from your earnings history rather than from the internet.

It runs on Claude and on more than $7.5 billion of real gig earnings across 100+ metro areas in the US, layered against your own numbers. When Sherpa tells you Saturday morning beats Wednesday afternoon in your zone, it's reading your history and your market and uses that to give you data-driven recommendations you can count on.

Spark taxes: projections and filing

Solo projects your Spark taxes year-round and files them.

Every classified mile and tracked expense feeds a running estimate: what you owe, what you've set aside, what's left before the next quarterly deadline. You see it in July, not for the first time in April.

Then Solo files. Annual Pro and Pro Plus members file federal and state returns from inside the app or on the web, with income and expenses already filled in from a year of tracking.

What Spark Drivers can deduct

Mileage is usually the biggest one. After that:

Phone and data plan at your business-use share

Hot bags and delivery equipment

Tolls and parking on deliveries

Roadside assistance

A share of car expenses if you claim actual costs

Solo tracks these automatically as you go, and Sherpa flags what you're missing. Just link your bank account to Solo using Plaid and all of your work expenses will be tracked automatically.

Best mileage tracker apps for Spark, compared

Most Spark shoppers end up choosing between four or five apps, and they solve genuinely different problems.

Solo's key difference is scope. It's the only one here that tracks earnings across every platform you shop or drive for, classifies your miles by matching them to completed jobs, projects your taxes year-round, and files your federal and state return in the app. The others hand you a report to take somewhere else.

Frequently asked questions

Does Spark Driver track mileage for shoppers?

Spark shows an estimated delivery distance for each order before you accept it, but that only covers the store-to-customer leg. It doesn't log the drive to the store, between stores, repositioning, or the drive home — and it doesn't produce an IRS-compliant mileage log. Solo tracks all of those miles by GPS and classifies them automatically by matching them to your completed orders.

Is there a free Spark mileage tracker?

Solo's free tier includes manual mileage tracking with unlimited trips — you tap start and stop around each shift. Automatic mileage tracking and classification, where Solo matches your drives to completed Spark orders without you pressing anything, starts on the Basic plan at $8/month ($96/year). All plans come with a 7-day free trial.

How do I track my Spark mileage?

Download Solo, link your Spark account, start your free trial, and turn on mileage tracking. Solo's GPS logs every drive in the background. When you complete an Spark order, Solo matches it to the drive it already recorded and files those miles as business. No start button, no swiping, no Sunday-night catch-up.

Does the IRS ask for proof of mileage on Spark?

If you claim a mileage deduction and get audited, the IRS expects a contemporaneous log — dates, distances, destinations and business purpose — recorded at or near the time of the trip. Spark's order distance estimates and weekly summaries don't meet that standard. Solo's GPS log does: it records every trip as it happens and ties each one to a completed job.

What's the best app for Spark Drivers who also drive for DoorDash?

Solo connects to 11 platforms, so your Spark, DoorDash, Shipt, and Uber Eats earnings all appear on one screen alongside your mileage and expenses. Most mileage trackers only track miles — Solo tracks the whole picture and projects your taxes across every app you work for.

What app helps Spark Drivers make more money?

Solo's Smart Schedule predicts what an hour will pay before you decide to work it, using data from over a million gig workers. Drivers using Smart Schedule earn up to 40% more per year on average. Pay Guarantee can also lock in an hourly floor for a scheduled shift — if you earn less than predicted, Solo pays the difference.

How much of my Spark mileage can I actually deduct?

Every mile driven for business purposes is deductible at the IRS standard rate — 76¢ per mile for July through December 2026. That includes the drive to the store, store to customer, between orders, and the drive home after your last delivery. Personal miles (errands, school runs) are excluded. Solo classifies these automatically so only business miles end up in your deduction.

Do I need a separate app if Spark already shows my delivery distance?

Spark's order distance is a pre-acceptance estimate of the delivery leg only. It doesn't include the drive to the store, repositioning, or the drive home, and it doesn't create a log the IRS would accept. On a typical evening, drivers drive two to three times the distance Spark shows. Solo captures all of it by GPS, ties each trip to a completed order, and produces a proper mileage log.

Which mileage tracker works if I multi-app between Spark Driver and Shipt?

Solo connects to both Spark and Shipt (and nine other platforms). It matches each completed order or order to the drive that produced it, regardless of which app the job came from, so you get one mileage log and one earnings view across all your apps. Most other trackers either don't connect to gig platforms at all or only track miles without linking them to jobs.

Can Solo file my Spark taxes, or just estimate them?

Both. Solo projects your tax liability year-round based on your tracked earnings, mileage, and expenses — so you always know what you owe before a quarterly deadline. Then, Annual Pro and Pro Plus members can file their federal and state returns directly from the app or on the web, with all of your income and deductions already filled in from a year of tracking.

Are Instacart tips tracked separately from batch pay in Solo?

Yes. Solo pulls your Instacart earnings breakdown directly from your linked account, so tips, batch pay, and bonuses each appear as separate line items. This matters at tax time — all of it is taxable income, and seeing the split helps you understand what's actually driving your pay. For Instacart shoppers, tips typically make up close to half of total earnings.
