You need your chart of accounts, sales tax setup, and payroll configured to handle each revenue type separately from the start. Trying to untangle mixed-up med spa books later costs more time and money than setting it up right.

Massachusetts sales tax is the first layer of complexity. Most personal services like facials, massages, and body treatments are not subject to sales tax. But retail product sales are taxable at 6.25%. When a client buys a serum or skincare kit to take home, you charge sales tax on that sale. When they receive a facial that includes products applied during the service, no sales tax applies because it’s part of the service.

Injectable treatments like Botox and fillers fall into a gray area depending on how they’re structured. When administered by a licensed medical professional as a medical service, they’re generally not taxable. But you need to be careful about how you categorize and document these services. Getting this wrong means either overcharging clients or underpaying the state and owing back taxes plus penalties.

Your QuickBooks setup needs to distinguish these categories from day one. Each service and product should be assigned the correct tax code so your POS transactions flow into your books accurately. Fixing sales tax errors after the fact is tedious and expensive.

Set up your chart of accounts to show service revenue, retail revenue, and injectable revenue as distinct income categories. This does more than keep the sales tax straight. It lets you see which parts of the business actually make money.

A med spa might gross $80,000 a month but lose money on retail because of inventory costs and shrinkage while making strong margins on injectables. You won’t know that unless your books are organized to show profitability by revenue stream. This visibility helps you make better decisions about what to promote, what to price differently, and where to invest.

Cost of goods sold matters here too. Track the cost of retail products you sell and the cost of injectable supplies separately. Your profit and loss statement should show you gross margins for each line of business.

Payroll gets complicated with mixed staff. Med spas typically employ a mix of front desk staff, aestheticians, nurses or nurse practitioners, and sometimes physicians. Each may have different pay structures. Hourly for front desk. Commission or salary plus commission for aestheticians. Higher salaries for medical staff.

Tips add another layer. Clients tip aestheticians and sometimes other providers. You need to track tips properly for payroll tax purposes, just like a day spa or salon.

Worker classification matters. If you have aestheticians who rent space and bring their own clients, they’re likely contractors who receive 1099s. Staff aestheticians on your schedule working your clients are employees. Massachusetts and the IRS both care about getting this right, and misclassification creates real liability.

Med spas tend to generate higher revenue than traditional day spas, which means more income flowing to the owner and more tax to plan around. Simona is a CPA and Enrolled Agent, so the bookkeeping and tax services she provides include real tax planning, not just filing.

For a profitable med spa owner, that might include timing equipment purchases for maximum deduction, structuring retirement contributions to reduce taxable income, and planning quarterly estimated payments so you’re not surprised in April. The planning happens during the year, not at tax time when it’s too late to change anything.

Your POS needs to feed clean data into QuickBooks with the right tax codes. Your payroll needs to handle tips and different pay structures accurately. Your chart of accounts needs to give you visibility into each revenue stream. And your sales tax filings need to reflect the correct taxable and non-taxable amounts.

When these pieces are set up correctly, the monthly close is straightforward and your financials actually tell you how the business is doing. When they’re not, you spend hours every month cleaning up data and still don’t trust the numbers.

If your med spa books are already a mess or you’re just getting started and want to set things up right, reach out for a consultation. Every med spa is a little different depending on what services you offer and how you structure your staff, so it’s worth talking through your specific situation.
