In this lesson

What you will learn

  • Explain which income must be reported, including cash, tips, and payment-app income.
  • Estimate self-employment tax on net earnings using a worked example.
  • Set aside money for taxes and know when quarterly estimated payments are due.
  • Keep simple records of income and business expenses, such as mileage.

How this connects to class: Module 3 mentions side jobs and Form 1099 but does not teach self-employment tax. This lesson shows the math with real numbers and gives drivers, cleaners, caregivers, and other independent workers a simple system for saving and keeping records.

Words to know

Self-employed
Working for yourself instead of for an employer. No one withholds taxes from your pay.
Net profit
Your business income minus your business expenses. Self-employment tax is based on this number, not on all the money you took in.
Self-employment tax
Social Security and Medicare tax for people who work for themselves. The rate is 15.3%.
Estimated tax
Tax you pay to the IRS during the year, usually four times, when no tax is withheld from your income.
Form 1099-NEC
A form a business sends to someone it paid who is not an employee, showing how much it paid.
Form 1099-K
A form payment apps, online marketplaces, and card processors send to report payments you received for goods or services.
Business expense
A cost you pay to do your work, such as supplies or business miles. It lowers your profit.

All income counts

If you are paid to drive for a rideshare app, deliver food, clean homes, braid hair, or care for children, and no one takes taxes out of your pay, you may be self-employed. That means you are in business for yourself, even if it is a part-time or side job. You must report what you earn, whether you are paid in cash, by check, through an app, or in tips.

One exception: if you work in one family's home and the family controls how you do the work, for example as a nanny or housekeeper, you may be that family's household employee instead. Ask a VITA volunteer if you are not sure.

You must report income even if you never get a tax form. Tax forms are only reports. Here is what you might get:

  • Form 1099-NEC from a business that paid you as a non-employee. For payments made in 2026, a business must send one if it pays you $2,000 or more. Before 2026, the amount was $600.
  • Form 1099-K from a payment app or online marketplace if you receive more than $20,000 for goods or services in more than 200 payments in a year. If you accept credit or debit cards directly, for example with a card reader, those card payments are reported on a 1099-K at any amount.
  • No form at all for many cash jobs. The income still counts.

Money a friend sends to split a dinner bill, or a gift from family, is not business income. Keep personal payments apart from business payments so your records stay clear.

You must file a federal tax return if your net earnings from self-employment are $400 or more, even if your total income is low.

Two taxes: self-employment tax and income tax

An employee pays 7.65% of their pay for Social Security and Medicare, and the employer pays another 7.65%. When you work for yourself, you pay both parts. This is called self-employment tax. The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.

The tax is not figured on all the money you take in. It is figured on 92.35% of your net profit. Net profit is your business income minus your business expenses. You can also deduct half of your self-employment tax when you figure your income tax.

You may also owe regular income tax. That depends on your total income, filing status, deductions, and credits. Many workers with low income owe little or no income tax after the standard deduction, but they still owe self-employment tax. Refundable credits, such as the Earned Income Tax Credit, can lower what you owe or even give you a refund.

Filing with an ITIN? You still report your self-employment income. Whether you also owe self-employment tax can depend on your tax residency, which is not the same as your immigration status. Ask a VITA volunteer to check.

Example

Marisol's delivery income in 2025

Marisol lives in Langley Park, Maryland, and delivers food with two apps. In 2025 the apps paid her $26,000, including tips. She kept a mileage log and her receipts.

Marisol's profit and self-employment tax for 2025
ItemAmount
Money from the apps, including tips$26,000
Business miles: 8,000 miles × 70 cents (the 2025 IRS rate)−$5,600
Business share of her phone bill−$300
Insulated delivery bags−$100
Net profit$20,000
Amount subject to self-employment tax: $20,000 × 92.35%$18,470
Self-employment tax: $18,470 × 15.3%$2,826

$20,000 × 92.35% × 15.3% = about $2,826

Marisol can deduct half of that, about $1,413, when she figures her income tax. Whether she owes income tax, and how much, depends on the rest of her tax return.

Her mileage log saved her money. Without it, her profit would be $5,600 higher, and her self-employment tax alone would be about $791 higher.

The IRS mileage rate changes. For 2026 driving, it is 72.5 cents a mile from January through June and 76 cents a mile from July 1 through December 31.

Set money aside every time you are paid

No one takes taxes out of gig pay. If you spend it all, the tax bill can be hard to pay. Protect yourself with a separate account.

  1. Open a second account just for taxes. Many banks and credit unions offer free or low-cost savings accounts. See our lesson on opening an account.
  2. Each time you get paid, move a set percentage into it. Self-employment tax alone is about 14% of your profit. If you may also owe income tax, save more. The worksheet in IRS Form 1040-ES or a VITA volunteer can help you choose a percentage.
  3. Do not use this money for bills. It is for your tax payments.
  4. Use it to pay your estimated tax on time.

$385 weekly profit × 15% = about $58 a week, or about $3,000 a year

For Marisol, saving 15% of her profit each week would cover her self-employment tax of about $2,826, with a little left over.

Pay during the year: estimated tax

The IRS expects you to pay tax during the year, as you earn income. If you expect to owe $1,000 or more when you file, you generally need to make estimated tax payments. If you pay too little or too late, you may owe a penalty, even if you get a refund later.

When estimated tax is due for 2026 income
Income earnedPayment due
January 1 to March 31, 2026April 15, 2026
April 1 to May 31, 2026June 15, 2026
June 1 to August 31, 2026September 15, 2026
September 1 to December 31, 2026January 15, 2027

If a due date falls on a weekend or holiday, you can pay on the next business day. To avoid a penalty, you generally must pay at least 90% of this year's tax, or 100% of last year's tax (110% if your income was over $150,000). DC, Maryland, and Virginia may also expect estimated payments for their income tax.

Ways to pay the IRS:

  • IRS Direct Pay: free, from a checking or savings account, with no sign-in.
  • Your IRS Online Account.
  • Debit or credit card: the card processor charges a fee.
  • Cash at a store, through an IRS-approved retail partner: there is a small fee and a limit on each payment. Pay at least 7 days before the due date. You can also pay cash for free at an IRS Taxpayer Assistance Center, by appointment.
  • A check by mail, with a Form 1040-ES payment voucher.

Have a W-2 job too? You can ask your employer to take out extra tax in Step 4(c) of your W-4 instead of making estimated payments. See Read Your Pay Stub and Fill Out Your W-4.

Records that save you money

Every business expense you can prove lowers your profit. Lower profit means less self-employment tax and less income tax. Use a paper notebook or an app. Either one works if you keep it up to date.

  • Income: save app summaries and monthly statements. Write down cash and tips on the day you get them.
  • Mileage log: for each work trip, write the date, the miles, and the reason. Write down your car's odometer reading at the start and end of the year.
  • Receipts: supplies, tools, uniforms, cleaning products, and the business part of your phone bill.
  • Parking and tolls for work trips. You can deduct these even if you use the standard mileage rate.
  • One account for business money, so your bank statements support your records.

Personal trips are not business miles. Traffic tickets and other fines are not deductible. If you want to use the standard mileage rate for a car you own, you must choose it in the first year you use that car for your business.

Keep your tax records for at least three years after you file.

Watch out

Common traps

  • Thinking cash does not count. It does, even with no form.
  • Spending the tax money. Then the bill comes in April and there is no money to pay it.
  • Not filing because you cannot pay. File on time anyway. The penalty for filing late is usually much bigger than the penalty for paying late, and the IRS offers payment plans.
  • Paying a company that promises to make your tax debt disappear. Many charge large fees up front. For free help with a tax debt or an IRS letter, contact a Low Income Taxpayer Clinic.

Tip

Why reported income helps you later

Reporting all your income can feel expensive, but it helps your future. If you have a Social Security number, the self-employment tax you pay earns Social Security credits toward retirement and disability benefits. In 2026, each $1,890 of earnings earns one credit, up to four credits a year.

Your tax returns are also proof of income. Landlords, lenders, and some programs ask for them when you rent an apartment, apply for a loan, or get ready for a mortgage. Income you never reported cannot help you then.

Key takeaways

  • All income counts, including cash and tips, even if you never get a Form 1099.
  • Self-employment tax is 15.3% of 92.35% of your net profit, or about 14% of your profit.
  • Move part of every payment into a separate tax savings account.
  • If you expect to owe $1,000 or more, pay estimated tax during the year, usually four times.
  • Records of your miles and expenses lower your profit, and that lowers your tax.
