Do You Have to Pay Taxes on Side Hustle Income?

The short answer: yes

Money you earn on the side is taxable income. That is true whether it came from freelancing, reselling, delivery apps, affiliate commissions, or cash from a neighbor for fixing their fence. It is also true whether or not anyone sends you a tax form.

The IRS says it plainly: you must report all income on your return, even if you do not receive a Form 1099 or any other information return. Nobody tells you this when you start. So here is the plain version, before the first payment lands.

This is general information, not tax advice. Your situation might have wrinkles this does not cover. When it does, the current IRS guidance and a qualified tax professional govern.

You may owe two kinds of tax

1. Income tax

Your side income gets added to everything else you earned during the year — your paycheck, for example — and income tax is figured on the total. Side income does not have its own separate bracket. It just stacks on top.

2. Self-employment tax

This is the one that surprises people. When you work for an employer, Social Security and Medicare taxes come out of your check, and your employer pays a matching share you never see. When you work for yourself, you pay both halves.

According to the IRS, you usually must pay self-employment tax if your net earnings from self-employment are $400 or more. The rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare. It is generally figured on 92.35% of your net earnings, and the Social Security part stops once your combined earnings reach an annual limit the IRS sets each year. You calculate it on Schedule SE and attach it to your Form 1040.

You are taxed on profit, not on everything you took in

The key word above is net. If you earned money and spent some of it to earn that money, you are generally taxed on what is left. Side-business income and expenses are usually reported on Schedule C.

Deductible expenses are generally the ones that are ordinary and necessary for your kind of work. Depending on what you do, that can include supplies, software, platform or payment fees, a share of your phone or internet, and business mileage. Personal expenses do not count just because you also used them once for work.

None of this helps if you cannot prove it. Keep receipts, and if you drive for the work, keep a mileage log as you go — the date, where you went, why, and the miles. Rebuilding a year of records the week before a deadline is miserable.

Nobody is withholding for you

At a regular job, taxes come out of every paycheck. Side income usually arrives whole. That feels great until the bill comes due.

The IRS says individuals generally have to make estimated tax payments if they expect to owe $1,000 or more when they file. You figure the amount with Form 1040-ES, and the year is split into four payment periods:

Income earned	Payment due
January 1 – March 31	April 15
April 1 – May 31	June 15
June 1 – August 31	September 15
September 1 – December 31	January 15 of the next year

If a due date lands on a weekend or legal holiday, the payment is on time if you make it the next business day. You can pay online through your IRS account, through the Electronic Federal Tax Payment System, by phone, through the IRS2Go app, or by mail. If you do not pay enough during the year, you may owe a penalty for underpayment on top of the tax.

If you also have a day job, there is an easier route

The IRS lets employees skip estimated payments by having more withheld from their regular paycheck instead. You file a new Form W-4 with your employer and ask for an extra amount each pay period. For a lot of people with a small side income, this is the simplest option: set it once and it happens automatically.

How much to set aside

People love to quote one percentage for this. Be careful with that. The right amount depends on your total income, your deductions, your filing status, and your state, so a number that is right for one person can leave another short.

Here is a method that works instead:

1. Use the worksheet in Form 1040-ES, or ask a tax professional, to estimate what your side income will add to your tax bill.
2. Turn that into a share of each payment you receive.
3. Open a separate savings account just for taxes.
4. Every time you get paid, move that share into it before you spend anything.
5. Recheck the estimate every quarter. If your side income grows, the share grows with it.

If you end up with extra in that account at filing time, good. That is a much better problem than the opposite.

Do not forget your state

Everything above is federal. Some states have their own income tax and their own estimated payment rules; others do not tax wages at all. Check your state’s revenue or comptroller website so you know which applies to you.

A simple system you can keep up with

• One separate bank account for side-income money in and business expenses out.
• A spreadsheet or notebook with every payment received and every expense paid.
• Receipts saved the day you get them — a phone photo in one folder is fine.
• A mileage log, if you drive for the work.
• Calendar reminders a week before each estimated-payment date.

When to get help

Get a qualified tax professional involved in your first year of self-employment income, if you have fallen behind, or if you receive a letter from the IRS. If your income is modest, the IRS’s Volunteer Income Tax Assistance program offers free return preparation to people who qualify. The IRS Gig Economy Tax Center is the official starting point for everything in this article.

Taxes are not a reason to avoid earning extra money. They are a reason to set it up right from the first payment. If you are just getting started, here is how to land your first freelance client.
