How to Track Income and Expenses for Taxes as a Gig Worker
When you work gigs—cleaning, delivery, handyman jobs, pet sitting, yard work, or any independent work—you're running your own business in the eyes of the IRS. That means you're responsible for tracking every dollar you earn and every expense you incur. Come April, you'll file a Schedule C and pay self-employment tax on your net profit, so good records aren't optional—they lower your tax bill and protect you in an audit.
This guide walks you through a simple, sustainable system for tracking income and expenses throughout the year. You'll learn what counts as a deductible expense, which records to keep, how to organize everything, and how to make tax time as painless as possible. Whether you use Lumo (which deposits your earnings in an in-app wallet so every job is documented) or work on other platforms, these principles apply.
- 01
Step 1: Open a separate checking account for business income
Person using mobile phone to deposit check into bank account Mixing personal and business money is the number-one mistake new gig workers make. Open a free checking account at a local bank or credit union and use it exclusively for gig income and expenses. Every time you cash out your earnings—from Lumo's wallet, Venmo, cash tips, or any other source—deposit it into this account. Pay for gas, supplies, tools, and other business costs from this account. At tax time, one bank statement will show your entire year of business activity. You don't need a formal business account; a personal checking account in your name works fine and often has no monthly fees.

Step 2: Log every gig and payment as it happens
Worker recording gig details in notebook with phone nearby Don't wait until December to reconstruct your income. Keep a simple spreadsheet or use a notes app on your phone. For each job, record the date, customer or platform, type of work, and amount earned. If you work on Lumo, your completed jobs and earnings are already documented in the app, which makes this step easier—you can review your job history and download a summary. For cash tips or side gigs outside any app, write them down the same day. At year-end, add up all the columns. This log becomes your gross income figure for Schedule C, and it's your defense if the IRS questions your reported income.

Step 3: Save every receipt for business expenses

Common deductions for gig workers include: mileage or actual vehicle expenses (gas, oil, repairs, insurance, registration), phone bill (the business-use percentage), supplies and tools, cleaning products, work clothing that's not everyday wear, equipment, advertising, and platform fees. Take a photo of every receipt the moment you get it and store the images in a folder on your phone or cloud drive labeled by month. Apps like Expensify or Shoeboxed can help, but a simple photo album works too. If you forget a receipt, note the date, vendor, amount, and purpose in your spreadsheet—it's better than nothing.

Step 4: Track your mileage with a logbook or app
Driver writing mileage and odometer reading in small notebook If you drive for gigs—delivery, mobile cleaning, going to supply stores, meeting clients—mileage is usually your biggest deduction. For 2024, the IRS standard mileage rate is 67 cents per mile. You must log the date, starting and ending odometer reading, total miles, and business purpose for every trip. A small notebook in your car works, or use a free app like MileIQ, Everlance, or Stride that uses GPS to track trips automatically. Personal commuting (home to your first job, last job back home) isn't deductible, but travel between jobs, to the store for supplies, or to meet a customer is. Track consistently—if you're audited, the IRS will disallow undocumented mileage.

Step 5: Set aside money for taxes every week
Person using banking app to transfer money into savings account No employer withholds taxes from your gig pay, so you owe income tax plus 15.3% self-employment tax (Social Security and Medicare) on your net profit. A safe rule of thumb: set aside 25-30% of every payment. Open a separate savings account labeled 'Taxes' and transfer that percentage as soon as you cash out. If you earn $500 this week, move $125-$150 into savings. In Lumo, workers keep 90% of the job price, so if you earned $100 from a job, set aside about $25-$30. Come January, you'll have a tax cushion ready. If you expect to owe more than $1,000 for the year, you're required to make quarterly estimated tax payments (April 15, June 15, Sept 15, Jan 15). Use IRS Form 1040-ES to calculate and pay online at irs.gov/payments.

Step 6: Reconcile your records monthly and at year-end
Calculator and receipts next to laptop showing spreadsheet of expenses At the end of each month, total your income log, add up your expense receipts, and compare your business checking account balance to your records. This 15-minute habit catches mistakes early—missing deposits, duplicate entries, forgotten expenses. At year-end, you'll have twelve clean monthly summaries to roll into your tax return. In January, platforms you worked for will send you tax forms: a 1099-K if you processed more than $5,000 in payments, or a 1099-NEC if you earned $600 or more. Match those forms to your own records. If they differ, use your records (they're more complete) and attach an explanation to your return. Organized monthly records make filing your Schedule C straightforward and stress-free.

Step 7: Work with a tax pro or use self-employment software
Tax preparer reviewing documents with self-employed client at desk Filing as self-employed is more complex than a W-2 return. If your gig income is more than a few thousand dollars, it's worth paying a CPA or enrolled agent who understands self-employment taxes and can find every deduction. Expect to pay $200-$500 depending on your location and complexity. If you prefer to file yourself, use software designed for self-employed filers—TurboTax Self-Employed, H&R Block Premium, or FreeTaxUSA—not the free basic versions. These walk you through Schedule C, calculate self-employment tax, and help you claim the Qualified Business Income deduction (up to 20% of profit). Either way, keep your records for at least three years in case of audit.
Pro tips
- If you drive, decide at the start of the year whether to track actual expenses or use standard mileage—you can't switch mid-year for the same vehicle.
- Pay yourself a regular 'paycheck' from your business account to your personal account; it makes budgeting easier and keeps finances clear.
- Use a credit card exclusively for business expenses; the monthly statement becomes an automatic expense log.
- If you hire help (a partner, a cleaner, a driver), you may need to file 1099-NECs for them if you pay more than $600 in a year.
- Consider opening a solo 401(k) or SEP IRA—contributions are deductible and reduce your tax bill while saving for retirement.
Frequently asked questions
- Do I have to report cash tips or under-the-table gigs?
- Yes. All income is taxable, whether it's reported on a 1099 or not. The IRS can audit you and estimate income based on bank deposits, so it's safer and smarter to report everything. The good news: you can deduct expenses against that income, which lowers your tax.
- How much will I actually owe in taxes as a gig worker?
- It depends on your total income and deductions, but expect to pay 15.3% self-employment tax plus your income tax bracket (10-22% for most gig workers). If you net $20,000 after expenses, you might owe roughly $4,000-$6,000. Quarterly estimated payments spread the burden.
- Can I deduct my phone, internet, and home office?
- Yes, but only the business-use percentage. If you use your phone 50% for gigs, deduct 50% of the bill. A home office must be a space used regularly and exclusively for business; if you do paperwork at the kitchen table, that doesn't count. Track your usage honestly.
Tracking income and expenses doesn't have to be overwhelming. Start with a separate bank account, log every job, save receipts, track miles, and set aside tax money from day one. Your monthly 15-minute reconciliation will save you hours of panic in April—and hundreds or thousands of dollars in legitimate deductions. If you're using Lumo as a worker, your earnings and job history are already organized for you, giving you a head start. Build the habit now, and tax season becomes just another task, not a crisis.
