You clock out, add up the fares, and it feels like a good night. Two hundred and twenty bucks. Except that number isn’t what you made, it’s what the app says it paid you, before gas, before tolls, before the part that never shows up until April: what the IRS considers yours to keep.

Short version: There are two genuinely different numbers hiding in a shift’s earnings. Cash in your pocket is gross fares minus what you actually spent, gas, tolls, parking, food, car washes. What’s actually yours is a smaller number, because self-employment tax and income tax still apply to your taxable profit, which isn’t the same as your cash expenses. The twist: your mileage deduction, 76 cents a mile as of mid-2026, usually shields more income than your actual gas receipts show, since it bakes in depreciation and wear the receipts don’t capture. The calculator below walks through both numbers so you know which one you’re actually looking at.

The Two Numbers That Get Confused

“How much did I make” has two honest answers, and mixing them up is where a lot of driver income math goes wrong. Cash in pocket is what’s left after real, out-of-pocket spending, gas, food, parking, tolls, car washes. What’s actually yours is smaller still, because a portion of your cash-in-pocket number needs to go toward taxes you haven’t paid yet. This piece and the calculator it supports cover the same honest-math territory as the rideshare earnings breakdown, just from the after-tax side of the ledger rather than the platform-fee side.

Why Your Mileage Deduction Beats Your Gas Receipt

Here’s the part that surprises most drivers: the IRS doesn’t ask what you spent on gas. It lets you deduct a flat rate per business mile instead, currently 76 cents, and that per-mile figure is built to cover more than fuel. It bakes in depreciation, maintenance, tires, insurance, the whole cost of operating the vehicle, not just what you paid at the pump. For most drivers, that means the tax deduction is meaningfully larger than the actual cash they spent on gas that day. That’s a genuine advantage, not a loophole, it exists because a car wears out from business use even on days when gas is the only thing you’d think to count.

A note on this exact number, since it will change: the 76-cents figure is current as of publishing, and it already moved once in 2026, the IRS made a rare mid-year adjustment, up from 72.5 cents, because rising vehicle costs outpaced the original rate they’d set for the year. Standard mileage rates typically update every January, so this number is worth rechecking at the start of each tax year, and occasionally mid-year too, as this year showed. If you’re reading this well after publication, confirm the current rate before trusting the calculator’s output as tax-precise.

What’s Actually Deductible, and What Isn’t

This trips people up because it’s genuinely counterintuitive in a couple of places:

Tolls and parking are deductible on top of the mileage rate. The IRS explicitly excludes these from what the standard mileage rate already covers, so they stack as an additional deduction, not something you’re double-counting.

Gas and car washes are not separately deductible if you’re using the standard mileage rate. They’re already priced into that 76-cents figure. Deducting your actual gas receipts on top of the mileage rate would be double-dipping, you pick one method (standard mileage or actual expenses) for a vehicle’s business use, not a mix of both. The full mileage deduction breakdown covers how that choice locks in and what the actual-expense alternative looks like.

Food is not deductible at all, for a normal working day. It’s a real cash cost, your stomach doesn’t care that the IRS won’t reimburse it, but it never reduces your taxable income the way mileage does.

The Tax Piece: Two Layers, Not One

Every dollar of self-employed profit carries self-employment tax, a flat 15.3% (technically applied to 92.35% of your net profit, a standard adjustment that mirrors what an employer would otherwise withhold), covering the Social Security and Medicare contributions a traditional employer would normally split with you. On top of that sits ordinary income tax, which depends on your total income for the year, not just this one shift, which is why the calculator asks for a rough bracket rather than pretending to know your full tax picture. For the precise version of this math across a whole quarter, factoring in the standard deduction and QBI, the Quarterly Tax Estimator does that full calculation, this tool is built for a faster, single-shift gut check instead.

A Day That Looks Worse on Paper Than It Felt in Real Life

Here’s a genuinely useful edge case worth knowing about: a high-mileage, lower-fare day can show close to zero taxable profit, or even a paper loss, once the mileage deduction is subtracted, even though real cash landed in your account. That’s not a trick or an error, it’s the mileage deduction doing exactly what it’s designed to do. It also means a day like that owes little to no tax on its own, even though you walked away with real money. Just remember that a single day’s paper loss doesn’t necessarily reflect your full-year tax picture once every shift gets added together.

A Quick Worked Example

A driver brings in $220 in fares and tips, drives 120 business miles, spends $18 on gas, $12 on food, $5 in tolls, and $4 in parking. Cash in pocket: $175. Mileage deduction at 76 cents: $91.20, plus the $9 in tolls and parking, for $100.20 in total deductions against $220 gross, leaving $119.80 in taxable profit. Self-employment tax on that: about $16.79. Add a 12% income tax bracket: another $14.26. Total tax set-aside: roughly $31. What’s actually theirs: about $144, still a solid day, just a real number rather than the $220 they might have assumed at a glance.
