start a – From choosing a money-making idea that fits your time and costs to setting up the right legal structure, securing an EIN, and getting the permits you need, this guide lays out the practical steps that turn seasonal ambition into something sustainable.
Summer is supposed to feel easy. Sunlight, weekends, and a little breathing room—at least that’s the promise. But for people looking to turn that downtime into income, the real work starts before the first customer shows up.
The first decision isn’t marketing or branding. It’s picking the business idea that actually matches your life. Lawn care demands daytime availability and comes with physical equipment and fuel costs. Tutoring can fit more flexible hours but requires specialized academic expertise and still keeps startup costs low. A swim instructor needs specialized expertise and safety certification. while pet sitting can mean restrictive schedules and a high degree of responsibility with minimal ongoing costs.
Other examples come with their own trade-offs: an ice cream truck brings considerable startup and overhead costs alongside a lot of interpersonal interaction. while pickleball or tennis coaching can stay flexible and keep startup and overhead costs low. The point is straightforward: you’re not just choosing something you could do in summer—you’re choosing what you can sustain.
Before you commit fully, you also have to validate that your idea can earn money. Talk with potential customers to check whether there’s a need and whether the market is already crowded with businesses offering the same service. Research local competition. Then run the numbers—calculate costs. estimate revenue potential. and figure out how long it will take to turn a profit.
A summer business still needs a foundation strong enough to hold. The warning is blunt: skipping the planning can leave you with an outcome like “building a sandcastle on wet sand.”
Once the idea is clearer, the next step is getting the basics right—especially the parts that determine whether the business is treated like a business at tax time.
Whether your summer venture counts as a business or a hobby matters. The IRS generally considers a money-making venture a business if the intention is to make a profit. Under the One Big Beautiful Bill Act (OBBBA). hobby income is taxable. but only the cost of goods sold is tax-deductible. The OBBBA permanently eliminated deductions for costs such as home office expenses. vehicle mileage. and software subscriptions when a venture is operated as a hobby.
If you operate as a business instead, you may deduct those and other ordinary and necessary expenses when calculating taxes. There’s also a key difference in self-employment taxes: hobbyists do not pay self-employment taxes (Social Security and Medicare), while business owners do.
That leads to one of the most consequential choices you’ll make: selecting a legal entity.
For a small seasonal business, the guide lays out the most common structures. A sole proprietorship is the simplest setup—no formal entity registration with the state. A one-owner business is considered a sole proprietorship by default. Profit and loss flow to the owner’s personal tax returns, and the owner carries complete financial and legal liability. Debts or lawsuits are the owner’s responsibility, putting personal assets at risk.
A general partnership applies when multiple individuals own a business without registering a formal entity. Profits and tax obligations flow through to the individual owners, and those owners are responsible for debts and legal actions. Personal assets are also at risk if the business can’t pay its bills or gets sued.
The limited liability company (LLC) is a different kind of trade-off. It requires filing formation documents and designating a registered agent in the state. The structure is popular because it keeps much of the administrative simplicity of sole proprietorships and partnerships. while adding liability protection similar to a corporation. The LLC is a separate legal entity. which protects members from personal liability for business debts and legal issues under most circumstances.
LLCs also offer tax flexibility, including the option to elect S Corporation status to reduce LLC members’ self-employment tax burden.
A C Corporation comes with more startup and compliance formalities. It requires filing formation paperwork with the state. designating a registered agent. appointing a board of directors. adopting bylaws. and completing other filings and tasks. A C Corporation is its own legal and tax-paying entity; owners (shareholders) are protected from business liabilities. The company pays corporate income tax. and some income gets taxed twice—first at the corporate level and again on shareholders’ personal tax returns when dividends are distributed.
The guide notes that if a C Corporation meets IRS criteria, it can avoid that double taxation by opting for pass-through tax treatment through filing for an S Corporation election.
After you decide on the legal structure. there’s a practical next step many entrepreneurs overlook until they need it: an EIN. Most businesses—whether year-round or seasonal—need an Employer Identification Number from the IRS. Any business that will hire employees needs one. Any registered business entity (such as an LLC or corporation), regardless of whether it will hire employees, also needs one.
An EIN functions as a business’s federal tax identification number and is used for federal payroll withholdings and deductions. income tax reporting. and other purposes. Financial institutions often require an EIN before opening business bank or credit accounts. and licensing agencies might request an EIN before issuing licenses and permits.
Then comes the part that can quietly sink a promising idea: money management. The guide doesn’t sugarcoat it—sloppy money management can derail a business quickly.
The recommendation is to open a dedicated business bank account, even for a short-term venture, and avoid commingling personal and business assets and expenses. Separate accounts make it easier to track business income, expenses, and overall performance.
Record-keeping is next. Process and record income and expense transactions promptly so you don’t fall behind. Documenting transactions as they happen is described as far easier and less confusing than catching up later with a pile of invoices and receipts.
Tax obligations also can’t be treated as an afterthought. Besides annual filings, many small business owners must pay income and self-employment tax quarterly. Even if income comes only during a few months. quarterly tax returns may still be required to demonstrate that no tax is owed. Additional state taxes and fees may apply depending on where the seasonal business operates. including franchise tax. sales tax. gross receipts tax. and more.
Legal compliance doesn’t stop at taxes.
Licenses and permits can be required even for a summer side hustle. and the rules vary by state and local jurisdiction. The guide lists common examples: a sales tax license (sales permit). food safety permit. local zoning clearances. retail food facility license. sign permit. health permit. general business license. fire permit. and construction permit.
For what’s required, it points readers to the SBA website as a starting place.
Once the business can operate legally, the next step is getting customers in the door. Whether you’re mowing lawns, organizing closets, remodeling bathrooms, vending shaved ice, or walking dogs, the guide stresses that the business won’t sell itself.
There are free and low-cost tools to build visibility: create a logo. set up a Google Business Profile. and use social media to raise awareness. Instagram and TikTok are highlighted as especially effective for visually driven businesses. Print business cards as a tangible marketing tool, and lean on word-of-mouth by networking in the local community.
But in summer entrepreneurship, the story doesn’t end when the season does.
A crucial question is whether you plan to exit the business after summer or resume next year—or even expand into a year-round operation. Your intentions determine what comes next.
If you plan to close at the end of summer. you’ll likely need to wind down operations and officially close the business. Selling may also be an option to discuss with an attorney and accountant. If you formed a legal entity like an LLC or corporation. you’ll need to file articles of dissolution with the state. close out accounts. and submit any forms and notifications so tax authorities and licensing agencies recognize the business is no longer active.
If you decide to operate year-round. the guidance is to keep complying with federal. state. and local rules to stay in good standing. You should also inform existing and prospective clients that you’ll be available beyond summer so you can build a steady customer base. The guide also points to revisiting your business structure—such as converting from a sole proprietorship or LLC to an S Corporation or C Corporation—if it could be more advantageous from a tax standpoint. It recommends discussing your situation with an accountant and attorney.
If you only pause after summer, compliance doesn’t magically disappear. States consider LLCs. corporations. and other registered entities as active businesses responsible for reporting. fees. and tax filings unless owners file articles of dissolution to close the entity. Federal. state. and local tax authorities will still require returns and reports even if no tax is due. unless the business has officially closed its tax accounts.
Licenses and permits also may need renewing or reapplying before resuming activities.
The season may be short, but the checklist isn’t. For people ready to seize a summer opportunity—whether it’s teaching. coaching. pet care. or a business that starts on a sidewalk or in a driveway—the guide’s core message is that timing matters. but structure matters just as much. Start by choosing the right idea. build a legal and financial foundation. and think ahead to what you’ll do when summer ends.

So basically pick a side hustle that fits your schedule? Easy.
I feel like everyone keeps saying “get permits” but nobody says how long that takes lol. Like can I just sell lemonade without doing all that EIN stuff?
Wait, tutoring needs “specialized expertise”… so does that mean you need a degree? My cousin just helps kids with homework and he’s been doing it for years. Also lawn care sounds expensive with the fuel costs, but everyone loves grass until it’s on their bill.
EIN and permits sounds like the government tax on trying to make money. I get that you need the legal structure but it feels like they make it impossible. Also ice cream truck overhead?? People do that by just buying a used truck and playing music, right? I didn’t think it was that official, thought it was more like a summer vibe hustle.
