Starting a Summer Side Hustle? What June Earners Need to Know About Taxes Before the First 1099 Shows Up

By Dr. Jose G. Cardenas, Chief Tax Strategist at The C & R Group, LLC

June is when a lot of people decide to make extra money.

Seasonal gigs. Weekend work. Freelance projects. Online selling. Delivery driving. Consulting on the side. A summer income stream that starts small and feels informal.

And that is exactly why tax mistakes happen.

The IRS says gig economy income is taxable and must be reported on a tax return, even if it comes from part-time, temporary, or side work, and even if it is not reported on an information return. The IRS also says taxpayers with net earnings from self-employment of $400 or more generally must file a return and pay self-employment tax.

That is why early June is the right time to talk about this.

Because the mistake is usually not earning the money.

The mistake is assuming a summer side hustle is too small to matter.

Extra income is still taxable income

A lot of people still think taxes only become real when a 1099 arrives.

That is not the rule.

The IRS says gig income must be reported whether or not the taxpayer receives a Form 1099-K, 1099-NEC, 1099-MISC, W-2, or any other information return. The IRS also says income can be paid in cash, property, goods, or virtual currency and still be taxable.

That means the real question is not, “Did I get a form?”

The real question is, “Did I get paid?”

A summer side hustle can create self-employment tax fast

This is where people get surprised.

They expect maybe some income tax later, but they do not realize self-employment tax can enter the picture too.

The IRS says you must file a return if you have net earnings from self-employment of $400 or more from gig work, even if it is a side job, temporary, or part-time. The Taxpayer Advocate Service also notes that one-half of self-employment tax is deductible as an adjustment to income on the federal return.

That means even a modest summer side hustle can carry more tax impact than people expect.

Not every side hustle is a business, but many are

Some people call everything a “business” the moment money comes in.

Others call everything a “hobby” because they hope that makes the taxes easier.

Neither assumption is safe.

The IRS says hobbies and businesses are treated differently and that the biggest difference is whether the activity is carried on with the intent to make a profit. The IRS FAQs also say no single factor is decisive and all facts and circumstances must be considered.

That means if someone is mowing lawns, selling goods, freelancing, tutoring, doing design work, or driving for pay with a real profit motive, they may be operating a business for tax purposes even if it still feels informal.

Payment apps do not make the income invisible

This is another common misconception.

People assume money received through an app somehow stays off the radar or does not count unless the platform issues a form.

The IRS says payments received through payment apps for goods and services may lead to a Form 1099-K, but whether the form arrives or not, taxable income still must be reported.

That matters because many summer side hustles now run through:

• payment apps,

• marketplace platforms,

• mobile invoicing,

• or direct transfers.

The payment method does not change the tax character of the income.

Side hustle workers may need estimated taxes too

This is where June planning becomes important.

If the side income is coming in without withholding, the taxpayer may need to plan for estimated payments instead of waiting for filing season.

The IRS says federal taxes are generally paid on a pay-as-you-go basis and estimated tax is used to pay tax on income not subject to withholding. The IRS specifically lists self-employment income among the kinds of income that may require estimated tax payments.

So if summer income is growing, June is the right time to ask whether tax money is being set aside at all.

Good records matter from day one

Many side hustles start casually and stay disorganized for too long.

That is expensive.

The IRS says taxpayers must keep records to substantiate the income and expenses reported on a return. For gig work, that means tracking income received and any legitimate business expenses tied to earning it.

That means summer earners should be keeping:

• payment records,

• dates,

• receipts,

• mileage if applicable,

• and a clear separation between personal and business activity.

The earlier that system starts, the easier tax season becomes.

People often overfocus on deductions and underfocus on reporting

This happens all the time.

Someone starts a side hustle and immediately asks what can be written off.

That is not the wrong question, but it is usually not the first question.

The first question is whether the income is being tracked correctly and whether the activity is being treated like a real taxable endeavor. The Taxpayer Advocate Service points small business owners to Publication 535 for business expenses, but that only helps if the income and records are being handled properly in the first place.

A deduction strategy without an income-tracking system is not really a strategy.

Employee gig work and contractor gig work are not taxed the same

Some summer earners work as employees. Others work as independent contractors.

That difference matters.

The IRS says if you do gig work as an employee, your employer should withhold tax from your paycheck. If you do gig work as an independent contractor, you may have to pay estimated taxes yourself.

That means two people can earn similar summer income and still face very different tax handling depending on how they are classified.

June is the right month to fix this early

This is the opportunity.

A summer side hustle that starts in June is still early enough to organize correctly:

• track every payment,

• separate business and personal spending,

• save for taxes,

• and avoid the “I’ll deal with it later” trap.

The IRS guidance is clear that gig income is taxable, records matter, and self-employment tax can apply sooner than many people expect.

That makes early June a far better planning point than next March.

What summer earners should review now

Before the side hustle grows, review:

• whether the work is employee income or contractor income,

• whether all payments are being tracked,

• whether the activity looks like a business or a hobby,

• whether net earnings may exceed $400,

• whether estimated taxes may be needed,

• and whether records are being kept from the beginning.

The IRS and TAS both point in the same direction: small business and gig income should be handled intentionally, not casually.

Final thought

A summer side hustle can be a smart move.

But smart income still needs smart tax handling.

The IRS says gig economy income is taxable even if there is no form, and net self-employment earnings of $400 or more can trigger filing and self-employment tax obligations. That means a side hustle is not too small to matter just because it started casually.

So if the money is starting to come in, do not wait.

Track it early.
Plan for taxes early.
And make sure the extra summer income does not turn into an avoidable tax surprise later.
