The day you take money for work, you are a business, and three things need tracking from that day: your business miles, your money in, and your money out. Those three feed Schedule C directly — income on Line 1, mileage on Line 9, expenses across the lines between. Miles matter most because they are the largest deduction and the only one that cannot be reconstructed credibly at the end of the year.
You picked up your first gig deliveries, or landed your first few clients, and the money started coming in. Then a quieter question shows up right behind it: wait, what am I supposed to be doing now? Do I need an accountant? A business license? Some special software? Am I already behind?
Here is the reassuring truth: getting started right is simpler than it looks. You do not need to be an accountant, and you are not behind. You need one shift in how you think, and then you need to track three things. That is the whole foundation. Get those three right from the beginning and everything else — taxes, deductions, knowing whether you are actually making money — falls into place.
Quick answer: The day you take money for work, you are a business. So do what a business does: track three things from day one — every business mile you drive, every dollar that comes in, and every dollar you spend on the work. Miles, money in, money out. Those three feed straight onto your Schedule C at tax time. You do not need an accounting degree; you need a consistent record.
The one shift: you are a business now
This is the mindset that changes everything, and most people miss it because nobody tells them. The moment you accept money for work, the IRS considers you a business — specifically, a sole proprietor. Not "someday when it feels official." Not "once I make enough." The first dollar. You do not have to file paperwork or form an LLC for this to be true; it just is.
That sounds intimidating, but it is actually good news, because being a business comes with a real advantage: you are taxed on your profit, not your revenue. Every legitimate cost of doing the work lowers what you owe. But there is a catch, and it is the reason this whole article exists — you can only claim what you can prove. The deductions are only as good as your records. Which brings us to the three things.
Three streams, one form
Everything you track feeds one place. Keep the three streams clean all year and your tax return is mostly done before you start.
Thing 1: Track every business mile
If you drive for your work, this is almost always your biggest single deduction — and the one people leave the most money on. The IRS lets you deduct a set rate for every business mile: 72.5¢ per mile for the first half of 2026, rising to 76¢ for the second half. Rack up 12,000 business miles in a year and that is well over $8,000 off your taxable income, from mileage alone.
But there are two catches, and both matter from day one. First, it has to be a real, contemporaneous log — the IRS wants the date, where you went, the business purpose, and the miles for each trip, recorded at the time, not guessed at in April. A log full of round numbers you reconstructed from memory is exactly what gets a deduction thrown out. (We break down what a compliant log actually needs in our guide to IRS mileage log requirements.)
Second, "business miles" is broader than most beginners think — the drive between deliveries, the trip to buy supplies, the drive to a client all count, not just the miles with a passenger or an order in the car. And the mileage rate is not the end of it: four more car costs stack on top of it. But it all starts with capturing the miles. Miles you do not record are simply gone.
Thing 2: Track every dollar that comes in
This one sounds obvious, and that is exactly why it trips people up. When your income arrives from several places — a gig app here, a direct client there, some cash, some tips — it is dangerously easy to lose track of the full picture. And you cannot rely on the platforms to hand it to you cleanly: you may get a 1099 from one app and nothing from another, even though all of it is taxable income whether a form shows up or not.
So you keep your own running record of every dollar you earn, from every source. This does two jobs. It makes sure you report your income accurately (the IRS gets copies of those 1099s, and mismatches draw attention). And it separates your real earnings from things that are not income — like tips, which have their own rules, or reimbursements. Knowing your true money-in number is also the only way to answer the question that actually matters: am I making money doing this?
Thing 3: Track every dollar you spend on the work
This is where the "you are taxed on profit" advantage becomes real — but only if you capture it. Every ordinary and necessary cost of doing your work is a potential deduction: the phone you take orders on, the hot bag, the supplies, the parking and tolls on business drives, the fees the platforms take out. Each one lowers your taxable income. Miss them, and you pay tax on money you actually spent to earn.
The rule for making these stick is the same discipline as your mileage: record it when it happens and keep the receipt. A deduction you cannot document is a deduction you cannot safely take. Most new self-employed people dramatically under-claim here, simply because they never wrote the expenses down and could not reconstruct them later. There are far more of these than beginners realize — our rundown of the tax deductions self-employed drivers miss most walks through the ones that add up.
Why these three, and why from day one?
Because all three flow into the same place: your Schedule C, the tax form every sole proprietor files. Your money in is your gross income at the top. Your miles and your money out are the deductions below it. What is left is your profit — the number you actually pay income tax and self-employment tax on. Here is how it all fits together, line by line, in our Schedule C guide for gig workers.
And "from day one" is not a nag — it is the entire trick. Self-employment income is not withheld for you like a regular paycheck, so you are responsible for knowing your own numbers. Track the three streams as you go and tax time is mostly a matter of reading off totals you already have. Try to reconstruct a whole year the night before the deadline, from memory and a glovebox full of receipts, and you will do two things: overpay, because you cannot prove half your deductions, and lie awake worrying whether your guesses would survive a second look. The work is small when it is daily. It is miserable when it is annual.
Track all three in one place, automatically
The three things are simple, but doing them by hand — a mileage notebook, a spreadsheet of income, a shoebox of receipts — is exactly what falls apart by March. TrakMiles Pro is built to be the whole foundation in one app: it logs your business miles automatically by GPS, records your income from every source, and captures your expenses as they happen, so your Schedule C is essentially done before tax season starts. It is a GPS mileage tracker with real accounting built in, made for people who drive for a living.
Start Your Free 14-Day TrialThe bottom line for getting started
You do not need to make this complicated. The day you take money for work, you are a business — so think like one and track three things: your miles, your money in, and your money out. That is the foundation the entire self-employed tax return is built on, and everything else, from your deductions to what you owe, grows out of those three clean records.
Start today, even if "today" is already a few months into driving. The best time to begin tracking was your first shift; the second best time is your next one. Get the three streams flowing, keep them clean, and you will spend tax season reading off numbers instead of dreading them — and you will keep every dollar you actually earned.

Frequently asked questions
I just started working for myself. What do I need to do for taxes?
Treat it like a business from day one and track three things: every business mile you drive, every dollar of income that comes in, and every dollar you spend on the work. Those three feed directly into your Schedule C at tax time. You don't need to be an accountant — you need a consistent record of miles in, money in, and money out.
Do I have to track mileage if I'm self-employed?
If you drive for work, yes — your business miles are usually the single largest deduction you have, worth 72.5 to 76 cents a mile in 2026. But the IRS requires a contemporaneous log showing the date, destination, purpose, and miles for each trip. Miles you don't record are a deduction you can't claim.
When do I have to pay taxes as an independent contractor?
Self-employment income isn't withheld like a paycheck, so most self-employed people pay estimated taxes quarterly and file a Schedule C with their annual return. That's exactly why tracking your income and expenses all year matters: it's how you know what you owe and prove what you can deduct.
What counts as a business expense when you're self-employed?
An expense is deductible if it's ordinary and necessary for your work — the phone you take orders on, the supplies you buy, the parking and tolls on business drives, the share of your car costs that stack on top of the mileage rate. The key is to record it when it happens and keep the receipt, so it's documented and defensible.
