Side Hustles: A Plain-English Guide to Making Extra Money

A side hustle is any work you do for money outside your main job. Driving for a rideshare app, freelancing on weekends, selling crafts online, tutoring, dog-walking — they all count. None of it is magic. It is just work, with extra paperwork the IRS cares about.

This is a plain-English starter guide. For a feel for how the extra income fits into your money, our budget calculator can help you sketch the numbers. For more vocabulary, see income and expense in the glossary, plus the Learn hub.

Why people start side hustles

A few common reasons:

• Pay down debt or build an emergency fund faster.
• Save for a specific goal (down payment, trip, big purchase).
• Test a business idea without quitting the day job.
• Use a skill that the day job does not.
• Build a portfolio for a career change.

The Bureau of Labor Statistics (BLS) tracks "multiple-job holders" each month at bls.gov, and the share of U.S. workers with side income has trended up for years.

The taxes part, in plain English

This is the piece most new side-hustlers miss. The IRS treats most side-hustle income as self-employment income, which has two layers of tax:

• Regular income tax at your normal rate.
• Self-employment tax of about 15.3% — this is the Social Security and Medicare portion (FICA) that an employer normally splits with you. As a self-employed person, you pay both halves.

The IRS expects you to pay as you go through estimated quarterly taxes, not just at filing time. The official IRS page is at irs.gov, and the IRS Free File program at irs.gov/freefile lets people under a certain income file federal taxes for free.

A common starter rule: set aside roughly 25-30% of every side-hustle dollar in a separate savings account for taxes. That covers federal income tax, self-employment tax, and a buffer for state tax in most cases.

Forms the IRS will care about

A few you will probably see:

• Form 1099-NEC — sent to you by clients who paid you $600 or more.
• Form 1099-K — sent by payment apps (Venmo, PayPal, Cash App) and online platforms once you cross IRS thresholds.
• Schedule C — the form on your tax return where you list business income and expenses.
• Schedule SE — where self-employment tax is calculated.
• Form 1040-ES — the worksheet for estimated quarterly taxes.

USA.gov Taxes at usa.gov/taxes is a friendly starting point if the IRS forms feel overwhelming.

What you can deduct

Self-employment income is taxed on net profit (income minus business expenses), not gross income. Keeping receipts is how you legally lower your tax bill. Common deductions:

• Mileage for business driving (the IRS sets a per-mile rate every year).
• Supplies and materials.
• A portion of your phone or internet if used for business.
• Software subscriptions and tools.
• A home office (if it meets IRS rules — see Pub 587).
• Health insurance premiums for self-employed people (with limits).

The IRS publishes plain-English deduction guides at irs.gov. The Small Business Administration (SBA) at sba.gov also has free recordkeeping templates that work for tiny side businesses.

Picking a structure

For most beginning side hustlers, a sole proprietorship is the default — no paperwork to start, you just report income on your personal tax return. As you grow, you may consider:

• A single-member LLC for liability protection.
• An S-corp election for certain tax savings once income is consistently high.

These come with new paperwork, fees, and rules. The SBA at sba.gov has plain-English comparisons. Talk to a qualified tax pro before choosing.

How to actually pick a hustle

A short reality check before sinking time and money:

• What skills do you already have? The fastest hustles trade on what you can already do.
• How much time can you commit? Be honest. Twenty hours a week is a lot.
• What up-front cost is involved? Some hustles have almost none. Some require equipment, licenses, or insurance.
• Is it allowed by your day-job contract? Some employers ban side work or competing work — read your employment paperwork.
• Will you actually do it on a Tuesday in February? Excitement fades fast.

The Department of Labor's Wage and Hour Division at dol.gov/whd covers worker classification (whether the work is "employee" or "independent contractor") and your rights under either status.

Common scams and traps

Where there are people looking for extra money, there are people looking to take their money. The Federal Trade Commission (FTC) regularly warns about:

• "Mystery shopper" jobs that send you a fake check, ask you to deposit it, and have you wire money back.
• "Reshipping" jobs that route stolen goods through your address.
• "Make $500 a day from home" pitches that turn out to be MLM recruitment.
• Fake check schemes of every other flavor.

The FTC's free job-scam alerts are at consumer.ftc.gov. If a "job" asks you to pay them up front or deposit a check and send most of it back, walk away.

When to set up a separate bank account

Once you have any meaningful side-hustle income, opening a separate bank account makes life much easier at tax time. You do not need a business account on day one — even a second personal checking account works. FDIC at fdic.gov and NCUA at ncua.gov insure deposits up to the standard limits at member banks and credit unions.

A note on advice

This is general information, not advice. As soon as side income gets meaningful, talking to a qualified tax pro is one of the highest-return moves you can make. Penalties for missing estimated taxes add up fast. A fee-only fiduciary or a non-profit credit counselor can also help you point the extra money at the goals that actually matter to you.
