She Was Already an NP. Then Her Botox Side Practice Took Off.
By Andrew Pham, CPA
TL;DR
A nurse practitioner's Botox side practice grew from a few referrals into a real business. Revenue isn't profit, an S-corp isn't automatic, and W-2 withholding doesn't cover business income. Jenny enrolled in Side Growth Partners' Platinum plan for three planning meetings a year and quarterly tax projections, so the plan changes as the practice does.
The numbers
- Day job
- Nurse practitioner in plastic surgery
- Side practice
- Botox injections, growing by referral
- Plan
- Platinum: 3 planning meetings a year
- Projections
- Quarterly tax projections
She already had a career
Jenny already had a career. She's a nurse practitioner working in plastic surgery. Good profession. Specialized skill set. Steady income.
But she wanted something of her own. So she started doing Botox injections on the side.
At first, it was exactly what you'd expect from a side business. A few clients. Referrals. Repeat appointments. People telling their friends.
Then it kept growing. Eventually, Jenny wasn't asking whether her side hustle could make money anymore. It already was.
Her question became: what do I do now that this is turning into a real business? That's when she reached out to Side Growth Partners.
When a side hustle starts becoming a business
There isn't a magic revenue number where a side hustle suddenly becomes a business. Usually, the questions just start getting more expensive.
Jenny now had income from her job as a nurse practitioner and income from her growing aesthetics practice. That brought up an entirely different set of questions:
- How much should she set aside for taxes?
- Does she need quarterly estimated payments?
- What expenses should she be tracking?
- Should she create an LLC?
- When might an S-corporation election make sense?
- What can she do for retirement?
- And most importantly: how much money is the practice actually making?
Botox revenue isn't Botox profit
Those aren't questions you want to discover the answers to next April. And this is where running a business gets more interesting.
A client pays for an appointment. Money hits the bank account. It feels like income. But revenue and profit are two very different numbers.
An aesthetics practice may have expenses for injectable products, medical supplies, professional insurance, payment processing, scheduling software, continuing education, licensing, marketing and treatment space.
So the number we really care about isn't simply how much did you collect. It's how much did the business actually keep. That number becomes important for almost everything that comes next.
When should an NP consider an S-corp?
Eventually, successful independent professionals tend to hear the same advice: "You should make an S-corp. You'll save money on taxes." Sometimes that's true. Sometimes it isn't.
There isn't a universal revenue number where an S-corporation suddenly becomes the right answer. An S-corp generally means payroll, a separate business tax return, additional compliance and the requirement that an owner performing services receive reasonable compensation.
The analysis should therefore be based on recurring business profit, reasonable compensation and the cost of maintaining the structure.
For someone whose practice is growing quickly, the answer can also change. What doesn't make economic sense today might make considerably more sense as the practice becomes more profitable. That's why we revisit it.
What about quarterly taxes?
Jenny also has something common among professionals building businesses on the side: W-2 income and business income at the same time.
That matters. Her paycheck withholding doesn't automatically tell us whether enough tax is being paid for the household once the practice starts generating meaningful profit. Business income can affect federal income tax, self-employment tax and state taxes.
Instead of blindly saving an arbitrary percentage of every deposit, we can build a tax projection around what's actually happening:
- How much has Jenny earned from her job?
- How much has already been withheld?
- How profitable is the practice?
- What deductions are available?
- What payments have already been made?
Jenny went Platinum
Now we're planning instead of guessing. As we talked through the practice, something became pretty clear. Jenny didn't just need somebody to prepare another tax return. She was building something.
So she enrolled in Side Growth Partners' Platinum advisory plan. Platinum gives us three planning meetings during the year plus quarterly tax projections. That means as the practice changes, we can change the plan with it.
- If profit accelerates, we update the projection.
- If an S-corporation starts making sense, we model it.
- If retirement contributions become part of the strategy, we plan for them.
- If Jenny eventually wants to reduce her employee hours and spend more time building her own practice, we can understand what the numbers need to look like before she makes that decision.
Tax preparation tells us what happened
The objective isn't to find clever deductions after the year is already over. It's to give Jenny enough visibility into her numbers to make better decisions while she's building the business.
Tax preparation tells us what happened. Tax planning gives us a chance to do something about it.
Maybe your side quest isn't Botox
That's what makes Jenny's story interesting. Botox isn't really the point. She had a valuable skill. She found people willing to pay her directly for it. Then they came back. Then they told other people. And eventually the little thing she was doing on the side started looking a lot more serious.
Maybe you're a physician consulting outside your practice. A PA building an aesthetics business. A CRNA taking 1099 work. A therapist building a private practice. A dietitian seeing private clients. A photographer filling her weekends. A corporate employee consulting after work. Or maybe you're doing something completely unrelated to your day job.
The pattern is the same. You don't necessarily wake up one morning and announce: I'm an entrepreneur now. Sometimes you just get really good at something. Someone pays you. Then somebody else pays you. And eventually you look at the numbers and realize: Oh. I think I built a business.
That's when the questions change. The tax return is the byproduct. The business is the asset.

How the work went
- 1
Separated revenue from profit
Looked past bank deposits to what the practice actually keeps after products, supplies, insurance, software, licensing and space.
- 2
Built a tax projection
Combined her W-2 pay, withholding and practice profit so set-asides and quarterly payments are based on real numbers.
- 3
Kept the S-corp question open
Set it to be revisited as recurring profit grows, weighing reasonable compensation and the cost of running the structure.
- 4
Enrolled in Platinum
Three planning meetings a year plus quarterly projections, so the plan changes as the practice does.
Questions people ask about this one
Does a nurse practitioner with a side practice need to pay quarterly estimated taxes?
Often, yes. Paycheck withholding from a W-2 job doesn't automatically cover the federal income tax, self-employment tax and state tax on side-practice profit. A tax projection that combines both incomes shows whether withholding is enough or estimated payments are needed.
When does an S-corp make sense for an NP or aesthetics practice?
There's no universal revenue number. It depends on recurring business profit, reasonable compensation for the owner's services, and the cost of payroll, a separate business return and extra compliance. The answer can change as the practice grows, so it's worth revisiting.
What expenses should an aesthetics practice track?
Common ones include injectable products, medical supplies, professional insurance, payment processing, scheduling software, continuing education, licensing, marketing and treatment space.
What's the difference between tax preparation and tax planning?
Tax preparation reports what already happened. Tax planning looks ahead during the year, using projections, so you can still make decisions that affect the outcome.
