Summer along the Wasatch Front is a busy season for earning. Contractors and landscapers are booked solid. Short-term rentals fill up. Teachers pick up side work. Teenagers take their first real jobs. People sell things — event tickets, equipment, a second vehicle — through apps that didn’t exist a decade ago.
Almost all of that income is reportable. Most of it is now reported to the IRS whether or not you report it yourself. That mismatch is one of the most common reasons people end up in our office, and it usually starts with a letter that arrives eighteen months after a good summer.
The paperwork follows you now
Payment apps, marketplaces, and gig platforms issue information returns to the IRS on payments they process. Banks report interest. Brokerages report sales. The agency’s matching program is automated and patient — it compares what third parties reported against what appeared on your return, and it flags the gaps.
Two things trip people up most often:
“It was just a hobby.” The line between a hobby and a business matters more than people expect, because it changes what you can deduct and how self-employment tax applies. If you’re operating with continuity and a profit motive, the IRS generally treats it as a business — with the reporting obligations that come along with it.
“It was reimbursement, not income.” Money that flows through a payment app isn’t automatically taxable, but if it was reported on an information return and doesn’t show up on your return, you’ll be asked to explain the difference. Contemporaneous records make that a five-minute conversation. Reconstructed guesses two years later make it something else.
Self-employment tax is the real surprise
The number that genuinely shocks first-time side hustlers isn’t income tax — it’s self-employment tax. When you work for someone else, your employer covers half of Social Security and Medicare. When you work for yourself, you cover both halves, and it applies to net earnings before any standard deduction enters the picture.
A profitable summer of contract work can generate a meaningful tax liability even for someone whose total income looks modest. If nothing was withheld and no estimated payments were made, that bill arrives all at once — and quarterly underpayment penalties are stacked on top of it.
Our tax experts see the same sequence every year: a great summer, a rough April, and a balance that couldn’t be paid in full. That’s the moment when a manageable situation starts turning into a collection case.
Employee or contractor? Get it right the first time
If your business brought on summer help, how you classified those workers matters enormously. Worker misclassification is an active enforcement priority, and the consequences run in one direction: back payroll taxes, penalties, and interest assessed against the business, often with personal exposure for the responsible person.
Whether someone is an employee or an independent contractor is a facts-and-circumstances question about control and independence, not a matter of what the paperwork says or what’s more convenient. If you’re unsure about a classification you made in May, July is a much better month to review it than the following spring.
Payroll tax problems are the most urgent category of tax resolution work we handle, precisely because the IRS pursues them hardest. They’re also the most preventable.
Three things to do before Labor Day
- Separate the money. A dedicated account for side-hustle income makes bookkeeping possible and audit defense straightforward. Commingled accounts are where deductions go to die.
- Set aside as you go. Move a percentage of every payment into a tax reserve the day it lands. The exact percentage depends on your bracket and your expenses — but reserving something beats reserving nothing.
- Cover the September estimated payment. Third-quarter estimated tax is due September 15. If your summer earnings outran your plan, that’s the deadline to catch up before penalties compound further.
If a letter already showed up
Notices about unreported income are common, and they’re not the end of the world — but they do have response deadlines, and the deadlines matter. Letting one lapse can turn a proposed adjustment into an assessment, and an assessment into collection activity.
If you’ve received a notice, bring it in unopened-anxiety and all. Tax Freedom Fighters has been handling exactly these cases from our office in Lehi since 1992. Sometimes the IRS is simply wrong and we say so. Sometimes the amount is right but the penalties can be abated. Sometimes there’s a genuine debt and the work is negotiating terms you can actually live with.
