Short answer
Tax preparation reports a year that is already over: the return, the depreciation schedule, the K-1s, prepared in the spring from whatever the books show. Tax planning makes the decisions while the year is open, from books closed every month: when a device is placed in service, what the owner-injector is paid and withheld, whether a 401(k) deferral runs through December payroll, where taxable income sits against the QBI thresholds, and how a December gift-card promotion changes the January estimate. Most of those close on December 31 and cannot be recovered in March. In the illustrative example, a $1.5 million practice that made two already-planned moves before year end paid about $23,700 less 2026 federal tax than the same practice with a return-only preparer. Balance Partners includes planning in the Med Spa Core engagement (from $1,500 a month) and offers a Fractional Tax Director role, scoped after a diagnostic, for multi-entity practices.
Key takeaways
- A return-only preparer works from fixed numbers in the spring; the only levers left are the Section 179 vs. bonus election, a SEP contribution and presentation.
- Device placed-in-service dates, owner salary true-ups, S-corp owner 401(k) deferrals, extra withholding to cure estimates and W-2 health insurance all close with the last 2026 payroll or on December 31.
- For a practice likely treated as a health SSTB, keeping joint taxable income under $403,500 preserves the full QBI deduction, and that can only be managed before year end.
- In the illustrative Atlanta example, installing a planned $60,000 device in December and deferring $24,500 cut 2026 federal tax by about $23,700, part timing, part deferral and part a larger QBI deduction.
- Med Spa Core includes bookkeeping, the monthly close, inventory, liability rollforwards, sales tax, payroll coordination and both business and owner tax planning and returns, from $1,500 a month, month-to-month after onboarding with thirty days' written notice.
- The Fractional Tax Director role covers multi-entity, multi-state and MSO / professional-entity practices and is scoped after a diagnostic as a flat monthly fee; return-only work is not something Balance Partners offers.
In this guide
"We do your taxes" means two very different things, and med spa owners usually find out which one they bought in the second week of April, when the preparer calls with a number. By then the laser was installed in January instead of December, the owner's salary ran all year at the figure set when the practice was half its current size, the December gift-card promotion added $90,000 of taxable income nobody had projected, and the only remaining question is how to pay. Nothing on that list was a preparation error. All of it was a planning absence.
This guide explains what a return-only preparer actually does and does well, what year-round planning adds for an aesthetics practice specifically, which decisions close for good on December 31, and what the difference can look like in dollars for a practice doing $1.5 million. It also explains how Balance Partners structures the two so you know what you are buying from us.
What a return-only preparer does
A preparer takes the year as it happened. In February or March, or on extension in September, they receive the QuickBooks file, the payroll reports, the 1099s and last year's return, and they produce the Form 1120-S, 1065 or Schedule C, the owner's Form 1040, the depreciation schedule on Form 4562, the QBI computation on Form 8995 or 8995-A and the K-1s. Good preparers do this accurately, defend the positions taken, and answer the IRS letter that arrives in August. That is real, skilled work, and for a business whose numbers do not move much from year to year it may be all that is needed.
The limit is built into the calendar. By the time the preparer opens the file, every number in it is fixed. What they can still choose is narrow: Section 179 versus bonus depreciation on devices that were already placed in service, a SEP-IRA contribution if the practice has one and the uniform-percentage rule does not make it prohibitive, the accounting method if a change is available, and how to present what happened. What they cannot do is move the install date of a device, change a salary that has already been paid, make an S election retroactive beyond the relief rules, or turn the December package sale into January income. And a preparer who sees a med spa file once a year is working from books that may show gift cards as revenue, injectables as an expense when purchased, and provider commissions a month late, because nobody tied them to the POS during the year.
What year-round planning adds for a med spa
Planning is the same tax knowledge applied while the year is still open, from books that are closed each month. The output is not a return; it is a projection and a short list of decisions with dates and dollar values. For an aesthetics practice the recurring decisions are specific. When to take delivery of a device so it is placed in service in the right year, and whether to elect Section 179 or let 100% bonus depreciation apply. What the owner-injector's salary should be given the treatments she performs, and whether a December bonus or a change in withholding fixes the estimated-tax position. Whether a 401(k) deferral needs to come out of the next payroll. Where household taxable income sits against the QBI thresholds, and whether the practice is likely a "health" specified service business, which decides whether staying under $403,500 of joint taxable income is worth $20,000 or nothing. How a December gift-card promotion changes the January 15 estimate on a cash-method return. Whether an MSO and professional entity should be formed, and if so, how to make the change effective January 1 so the books, payroll and merchant accounts start clean.
Planning also catches the things that are not tax moves at all but become tax problems if ignored: the year-end inventory count that sets the cost-of-treatment deduction, the W-9 from the medical director for the $2,000 1099 threshold, the health insurance premiums that have to be on the owner's W-2 by the time payroll closes the year. None of these require cleverness. They require someone looking at the practice in October with the authority to say "do this before December 31."
Decisions that close on December 31
The full working list is in our 2026 year-end checklist for med spas. This table shows which items a preparer can still touch in March and which are gone.
| Decision | Last day to act for 2026 | What a return-only preparer can do in March |
|---|---|---|
| Deduct a device in 2026 (Section 179 or 100% bonus) | December 31: delivered, installed and ready for use | Choose 179 vs. bonus on devices already in service; nothing on a January install |
| Owner-injector salary true-up or bonus through payroll | Last 2026 payroll | Nothing; a January payment is 2027 wages or a distribution |
| S-corp owner's 401(k) deferral | Last 2026 payroll | Nothing; deferrals must come out of 2026 wages |
| More-than-2% shareholder health insurance on the W-2 | Before W-2s are finalized | Corrected W-2s, with the payroll provider's cooperation |
| Extra withholding to cure estimated-tax underpayment | Last 2026 payroll | Nothing; late estimates only stop interest going forward |
| Managing taxable income under the QBI threshold | December 31 (device, deferral, salary) | Only the SEP contribution, if a SEP exists |
| Entity change or MSO structure effective January 1, 2027 | Documents signed and payroll set up before year end; Form 2553 by March 15, 2027 | File a late or prospective election; cannot clean up a mid-year start |
| Year-end injectable and retail inventory count | On or about December 31 | Estimate from purchases, which weakens the deduction on audit |
| Prepaying 12-month expenses (cash method) | Paid by December 31 | Nothing |
| Still open after year end | SEP-IRA establishment and funding to the extended due date; sole proprietor's solo 401(k) to April 15, 2027; 179 vs. bonus election; S election for 2027 to March 15, 2027 | These are the preparer's levers |
Worked example: a $1.5 million practice in Atlanta (illustrative)
An illustration with round numbers, not a client, and federal tax only. A married couple own a two-provider aesthetics practice in Atlanta, Georgia, taxed as an S corporation, with $1.5 million of revenue. The owner-injector takes a $150,000 salary; the practice pays $500,000 of total W-2 wages. The spouse earns $60,000 at an outside job. They file jointly with the standard deduction. In October, closed books project $280,000 of ordinary income on the K-1 for 2026. Their CPA treats the practice as a health specified service business for QBI purposes. A $60,000 device is scheduled for delivery in February 2027, and the practice has a 401(k) for the team that the owner has not used.
| 2026, joint return | Return-only (no changes before December 31) | Planned (device installed in December; $24,500 deferral) |
|---|---|---|
| Owner W-2 Box 1 | $150,000 | $125,500 |
| K-1 ordinary income | $280,000 | $220,000 |
| Spouse wages | $60,000 | $60,000 |
| Taxable income before QBI deduction (after $32,200 standard deduction) | $457,800 | $373,300 |
| QBI deduction | $35,700 (36% into the $403,500–$553,500 range, so 64% of QBI counts) | $44,000 (full 20%; below the threshold) |
| Taxable income | $422,100 | $329,300 |
| Federal income tax (2026 brackets, rounded) | $88,000 | $64,200 |
The gap is about $23,700 of 2026 federal tax. Be clear about what it is made of. The $60,000 device deduction is timing: placed in service in February it would be deducted in 2027 instead, so the permanent value is the difference between a 32% year and whatever 2027 brings, plus its effect on the QBI phase-in. The $24,500 deferral is tax deferred, not forgiven, and it is now in the owner's retirement account rather than the operating account. The $8,300 increase in the QBI deduction is a real 2026 saving that exists only because the first two moves pulled taxable income under $403,500. If the CPA had concluded the practice is not a health SSTB, the return-only QBI deduction would have been $56,000 and the gap about $17,400. Either way, none of it is available to a preparer who first sees the file in March, and none of it required spending a dollar the practice was not already going to spend.
Two items the table leaves out because they are exposures rather than savings. If the practice paid $20,000 of the owner's health premiums and nobody put them on the W-2, the owner loses that deduction. And if the owner's $150,000 salary was set three years ago when she was the only injector, a reasonable-compensation review may say it should be higher, which costs payroll tax but removes an audit issue that a preparer can only report, not fix.
How Balance Partners structures it
We do not sell return-only engagements, and a practice that only wants a return prepared is not a fit for us. The Med Spa Core engagement, from $1,500 a month and month-to-month after onboarding with thirty days' written notice, includes the bookkeeping and monthly close by the 10th business day, the package, membership and gift-card liability rollforward tied to the POS, injectable and retail inventory and cost of goods sold, provider commission tie-outs to payroll, retail sales tax by state, payroll coordination, and both business and owner tax planning and returns, with answers within one business day. Planning is inside the fee because it cannot be done without the close: every projection we run starts from the books we reconciled last month.
For practices past about $1 million, with two or more locations, or operating through an MSO and professional entity, the Fractional Tax Director role goes further: multi-entity and multi-state tax strategy, intercompany management fees, the QBI and reasonable-compensation analysis across entities, state pass-through entity tax elections and the tax side of a financing or sale, delivered personally by Jenny Gao, CPA, EA. It is scoped after a diagnostic and quoted as a flat monthly fee; we do not publish a price because the scope varies with the structure. Cleanup and catch-up work, when the books are not yet in a state that supports planning, is quoted separately as a one-time fixed project.
| Return-only preparer | Med Spa Core | Fractional Tax Director | |
|---|---|---|---|
| When the work happens | February–April, or on extension | Every month, with a fall projection and a December close | Year-round, across entities and states |
| Source of the numbers | Whatever QuickBooks shows when the file arrives | Books we close by the 10th business day, tied to the POS | Same, plus intercompany and consolidated views |
| Decisions influenced | Depreciation election; presentation | Device timing, salary, deferrals, estimates, QBI threshold, gift-card timing, 1099s | Entity structure, MSO fees, multi-state, PTE elections, exit |
| Best fit | A stable business with no moving parts | Single- or two-location practices, roughly $500K–$5M | Past about $1M, multi-location or MSO / professional-entity structures |
| Terms | Varies | From $1,500 a month; month-to-month after onboarding, thirty days' written notice | Flat monthly fee scoped after a diagnostic |
What usually goes wrong
The most expensive misunderstanding is assuming planning is included. An owner pays for a return, receives a return, and believes someone was watching the year. Ask directly: who projects my 2026 taxable income, in what month, from which books, and who tells me the amount and date of each move? If the honest answer is "we'll see when we do the return," you have bought preparation.
The second is planning from bad books. A projection built on cash-basis QuickBooks that shows December package sales as revenue and a $40,000 injectable order as an expense will confidently recommend the wrong estimate and the wrong device decision. The third is treating planning as a once-a-year event in December, after the gift-card promotion has run and the last payroll is scheduled. And the fourth is chasing deductions: buying a device the schedule cannot fill, or prepaying expenses that move a deduction into a year where it is worth less, because someone framed it as a tax move rather than a business decision.
When to get help
If your practice has crossed roughly $500,000 of revenue, added a provider, started selling packages or memberships, or is considering a second location or an MSO structure, the year has too many moving parts for a once-a-year return to capture, and the decisions that matter close on December 31. Our med spa tax planning and preparation work is built into the Med Spa Core engagement so the projection comes from books we closed last month, and the Fractional Tax Director role covers multi-entity practices that need more than that.
If you are not sure which one you have been buying, request a 20-minute fit call and bring last year's return and your current P&L. We will tell you what was decided for you by the calendar last year, and what is still open for this one.

Is tax planning included when a CPA prepares my med spa's return?
Not unless the engagement says so. Many preparers will answer questions during the year, but a projection of your taxable income from closed books, with specific moves and deadlines, is a separate service. Ask who projects the year, in which month, from which books, and who tells you the amount and the date of each move.
What can a preparer still do for 2026 after December 31?
Elect Section 179 or bonus depreciation on devices already placed in service, fund a SEP-IRA up to the extended due date if one exists and the uniform-percentage rule is affordable, make a sole proprietor's solo 401(k) deferral by April 15, 2027 under SECURE 2.0, and file the 2027 S election by March 15, 2027. Salary, S-corp owner deferrals, device install dates, W-2 health insurance and the estimated-tax cure through withholding are closed.
Does planning mean buying equipment to get a deduction?
No. Planning moves a purchase the practice was already going to make into the year where the deduction is worth more; it does not create a reason to buy. A device the schedule cannot fill costs far more in cash than it saves in tax, and prepaying expenses just shifts a deduction. If someone frames a purchase as a tax move first, that is a warning sign.
Why does Balance Partners include tax planning in the monthly fee instead of selling it separately?
Because the projection is only as good as the books it comes from. The Med Spa Core close ties packages, gift cards, inventory and commissions to the POS every month, so the fall projection starts from reconciled, tax-basis numbers. Selling planning without the close would mean projecting from books we had not seen, which is how the wrong estimate and the wrong device decision get made.
When does a med spa need a Fractional Tax Director rather than the Core engagement?
When the practice has passed about $1 million, operates two or more locations, or runs through an MSO and a professional entity, so that intercompany fees, multi-state filings, pass-through entity tax elections and the QBI and reasonable-compensation analysis span more than one return. The role is delivered personally by Jenny Gao, CPA, EA, scoped after a diagnostic and quoted as a flat monthly fee.
