Gym Owner Bookkeeping California: Memberships and Tax Guide

Running a gym, CrossFit box, yoga studio, Pilates studio, boxing gym, or spin studio in Southeast Los Angeles is different from running a service-based business. You have recurring membership revenue, which should be predictable but often is not tracked correctly. You sell merchandise (protein powder, gear, apparel), which is subject to California sales tax while your membership fees are not. You own capital assets (equipment, machines, computers) that must be depreciated, not expensed. You employ personal trainers, class instructors, and front desk staff, and under California AB5, most trainers are employees, not 1099 contractors, regardless of what you might have agreed to. And if you have employees, CalSavers is mandatory if you do not have a retirement plan.

The bookkeeping that connects these pieces is straightforward once the structure is in place. But getting the structure wrong is costly: misclassifying trainers, mixing membership and merchandise revenue, or failing to capitalize equipment will distort your profitability, trigger tax problems, and make it hard to know which revenue streams are actually working.

This guide covers the financial recordkeeping gym owners and fitness studio owners in Downey, Compton, Lynwood, South Gate, Huntington Park, and Southeast Los Angeles County need to understand. Each section connects to a real bookkeeping decision or tax rule, so you can see exactly where the structure affects your bottom line.

Revenue Streams: Separating Membership, Drop-In, Personal Training, and Merchandise

A fitness studio typically has multiple revenue streams, and the single biggest bookkeeping mistake is commingling them. You need to know which revenue types are generating the most income, which are profitable, and which are barely covering their costs.

Monthly memberships. Your core revenue is likely monthly recurring memberships. Members pay a flat fee each month for unlimited classes or a set number of visits. Track this as "Monthly Memberships" revenue. Record it when the payment is received or when the membership is activated, depending on your accounting method (cash or accrual). If members can pause or freeze their memberships, make sure your POS or billing system tracks active vs inactive memberships so your revenue count is accurate.

Annual memberships. Some members pay upfront for 12 months of access. This is not revenue all at once. Under accrual basis accounting (which you should be using if you have employees and payroll), annual membership payments are a deferred revenue liability when received. You recognize the revenue ratably over the 12-month period as the membership service is delivered. For example, a 1,200 dollar annual membership is 100 dollars per month of revenue. This matters for quarterly estimated tax planning because your actual income each quarter is the monthly portion, not the full amount received upfront.

Day passes and drop-in classes. Some studios sell day passes or single-class drop-ins. Track these separately from memberships so you can see how many non-members are converting to members. If drop-in revenue is high, you have a large audience of people trying your classes; if it is low, your marketing is not reaching new prospects.

Personal training packages. Personal training is almost always a higher-margin revenue stream than group classes. Track it separately. If you offer packages (10 sessions, 20 sessions), recognize revenue as each session is delivered, not when the package is purchased upfront (same principle as annual memberships).

Merchandise sales. Protein powder, supplements, gym gear, apparel, water bottles, and other tangible goods are merchandise revenue, not service revenue. Separate this account from class and membership revenue because merchandise is subject to California sales tax while services are not. Every merchandise sale needs to include the applicable sales tax, recorded separately in your liability account "Sales Tax Payable."

CDTFA Sales Tax: Fitness Services vs. Merchandise

California's rule on fitness is straightforward but widely misunderstood: gym membership fees and fitness class fees are not subject to sales tax because they are services. However, merchandise is taxable.

Memberships and unlimited classes are services. You are providing the use of your facility and the benefit of instruction or group participation. Sales tax does not apply. Monthly membership revenue, day pass revenue, and personal training session revenue are all non-taxable service revenue.

Merchandise is anything tangible that you sell (protein powder, supplements, apparel, yoga mats, towels, water bottles). These are subject to California sales tax. The rate is 7.25 percent plus any local district tax, which in Southeast Los Angeles ranges from 9 to 10.25 percent depending on the city. You must register with the California Department of Tax and Fee Administration (CDTFA) for a seller's permit and file quarterly returns reporting your merchandise sales and the tax collected.

Do not combine merchandise and service revenue on a single invoice or receipt. If a customer buys a membership renewal and protein powder, the invoice should show: "Monthly Membership: 150 dollars (not taxable)" and "Protein Powder: 40 dollars plus tax = 44 dollars" (assuming 10 percent local rate). This separation is critical for your CDTFA reporting.

Set up your point of sale (POS) system to separate taxable and non-taxable items. Most POS systems let you tag items as "taxable" or "non-taxable." If you are unsure how a specific product should be classified, consult the CDTFA or a tax professional before selling it.

File CDTFA quarterly returns. Your return is due the last day of the month following the quarter: April 30 for Q1, July 31 for Q2, October 31 for Q3, and January 31 for Q4. The return reports your total merchandise sales and the tax collected. Late filing and late payment both trigger automatic penalties.

Equipment Depreciation and the One Big Beautiful Bill Act (OBBBA)

Fitness equipment is a significant capital investment: treadmills, stationary bikes, free weights, squat racks, cable machines, rowing machines, yoga mats, sound systems, and computers for class management (if you use Mindbody or a similar booking system). These are capital assets, not immediate expenses.

Under federal tax law, you must depreciate these assets over their useful life, or you can elect to expense them using Section 179 expensing or bonus depreciation. The One Big Beautiful Bill Act (OBBBA), signed in January 2026, made a major change to equipment deductions: it allows 100 percent first-year bonus depreciation for qualifying equipment placed in service in 2026. This is a significant benefit that many gym owners do not know about.

Under OBBBA, if you purchase a 10,000 dollar treadmill in 2026 and place it in service in your gym, you can deduct the full 10,000 dollars in 2026. You do not depreciate it over five years; you can take the entire deduction in the year it is placed in service. This reduces your 2026 taxable income and can result in a tax refund if your business has other income to offset.

Alternatively, if you prefer to depreciate equipment rather than take the full bonus depreciation, you can use Section 179 expensing (approximately 1.16 million dollars limit for 2026) or standard MACRS depreciation over the useful life (typically 5 to 7 years for gym equipment).

To claim any of these deductions, you must track each piece of equipment with the purchase date, cost, and in-service date. Create a fixed asset register in your accounting system that lists every significant piece of equipment, its cost, and the depreciation method elected. Consult your CPA to determine the best method for your situation because the choices have different tax outcomes.

Small equipment and supplies. Items under a certain threshold (such as yoga mats or resistance bands) can sometimes be expensed directly if the total cost is immaterial. But larger items and machines must be capitalized. When in doubt, capitalize it and depreciate it; it is easier to correct an overstatement of fixed assets than to defend an improper immediate expense.

Personal Trainers and Staff Classification Under AB5

California AB5 applies a strict ABC test for worker classification. The law presumes that all workers are employees unless the business can prove all three parts of the test. For personal trainers and fitness instructors, this is a high bar.

The ABC test for trainers. Part A requires that the worker is free from control and direction. If you require your trainers to follow a specific curriculum, teach at scheduled times, work in your facility, and train your members, this part fails. They are not free from your control.

Part B requires that the work is outside the usual course of your business. Personal training and fitness instruction are the core of a gym's business. For a trainer providing services to your members, this part fails. The work is exactly the usual course of your business.

Part C requires that the worker is customarily engaged in an independently established trade. A trainer working exclusively for your gym, on your schedule, for your members, is not independently established. This part fails.

Because all three parts must be satisfied and Parts A and B almost always fail, personal trainers employed by your gym are presumed to be employees under AB5, not 1099 contractors. Misclassifying them as independent contractors is a high-risk error that triggers California Employment Development Department (EDD) enforcement, back payroll taxes, and penalties.

The exception. The only case for 1099 treatment is a trainer who operates a clearly independent business, works for multiple gyms and clients, sets their own rates, carries their own liability insurance, and is not under your supervision. A traveling specialist who serves five gyms in the area, invoices each one separately, and is not integrated into your operations might qualify. But a trainer who teaches your 6 a.m. class, works your member sessions, and depends on your referrals for income is an employee, not a 1099 contractor.

Practical classification. Classify all trainers and instructors as W-2 employees. Set up payroll, register with the EDD, withhold and remit payroll taxes (federal income tax, Social Security, Medicare, SDI, and state unemployment). File quarterly DE 9 forms. This is the safe path. If you have a trainer who genuinely qualifies for 1099 treatment, your CPA can document that, but do not assume it without professional review.

Payroll, Workers Compensation, and CalSavers

If you have even one W-2 employee (trainer, instructor, front desk staff), you have payroll obligations in California.

Payroll taxes and withholding. As an employer, you must withhold federal income tax, Social Security tax (6.2 percent of wages up to the annual cap), Medicare tax (1.45 percent of all wages), California state income tax, California State Disability Insurance (SDI), and file quarterly with the EDD. You also pay employer portions of Social Security and Medicare, plus federal and California unemployment taxes.

Set up payroll using a service such as Gusto, Intuit Payroll, or QuickBooks Payroll so the withholding and remittance are handled correctly and on time. Payroll is not optional, and late payments trigger penalties that accumulate fast.

Workers compensation. California requires workers compensation insurance for all employees. For fitness staff (trainers, instructors), the workers compensation premium rate is high because the work carries injury risk. Your premium is calculated as a percentage of payroll. When you are pricing your personal training services or estimating labor cost, workers compensation must be included in the total loaded cost, not just the wage.

CalSavers. If you have one or more W-2 employees and you do not offer a qualified retirement plan (such as a 401(k), SEP-IRA, or Simple IRA), you are required to be enrolled in California's CalSavers program. CalSavers is a state-facilitated IRA program. You register with CalSavers and set aside approximately 5 percent of gross wages per employee for CalSavers contributions each pay period. Employees can opt out if they already have a retirement plan, but the program must be in place. Failure to enroll when you have employees triggers penalties from the California Department of Industrial Relations.

Lease, Facility, and Operating Expenses

Operating a fitness facility means significant ongoing costs that are all deductible:

• Facility rent or mortgage. Monthly lease payments are deductible. If you own the building, mortgage interest is deductible, but principal is not (track these separately in accounting).
• Utilities. Gyms have high electricity, water, and HVAC costs because the facility runs long hours, is climate-controlled, and has showers. Track utilities as a single expense category or break them out by type (electric, water, gas) if you want to see which is the largest cost.
• Insurance. General liability insurance, property insurance, equipment insurance, and an umbrella policy are all deductible. These are significant costs for a facility with members and equipment, so track them carefully.
• Cleaning and janitorial. If you contract with a cleaning service or employ a cleaner, those costs are deductible. If you provide cleaning supplies to members (towel services, sanitizing spray), track those supplies as an operating expense.
• Software and membership platform. Mindbody, ClassPass, Zen Planner, and other class management and billing platforms charge monthly fees. These are deductible operating expenses.
• Payment processing fees. Credit card processor fees (Stripe, Square, etc.) for member payments are deductible.

Quarterly Estimated Taxes for Fitness Studio Owners

If you operate your gym as a sole proprietor, LLC, or S-corporation, you pay quarterly estimated taxes to the IRS and California FTB. These are due on April 15, June 15, September 15, and January 15 for federal, and April 15, June 15, and January 15 for California (California does not have a September payment).

Estimate your annual net profit (revenue minus all deductible expenses) and apply the tax rates. If you underestimate and underpay, you will owe the difference plus penalties when you file your return. If you overpay, you will get a refund. A bookkeeper or CPA can help you calculate the correct quarterly amount based on your year-to-date performance.

Common Mistakes Gym Owners Make

Commingling revenue streams. Not separating membership, drop-in, personal training, and merchandise revenue makes it impossible to see which are profitable.

Treating equipment as immediate expense. Equipment purchases should be capitalized, not expensed. Missing the OBBBA bonus depreciation deduction leaves money on the table in 2026.

Misclassifying trainers as 1099 contractors. Under AB5, this is a high-risk error that triggers EDD enforcement.

Not separating merchandise from service revenue. Merchandise is taxable; services are not. Failing to separate them results in incorrect CDTFA filings and overpaid sales tax.

Recognizing annual membership revenue all at once. Annual memberships should be recognized ratably over the 12-month period, not upfront.

Not enrolling in CalSavers when required. If you have employees and no retirement plan, CalSavers enrollment is mandatory. Not enrolling triggers state penalties.
