Pool Service Tax Deductions (2026)

Last updated July 2026.

A self-employed pool service and cleaning business writes off the ordinary costs of servicing a route: chemicals and test supplies, nets, brushes, vacuums, and pumps, the service van and its mileage between accounts, uniforms, licensing and permits, professional liability insurance, phone and scheduling software, and marketing to win new pool accounts. Because a pool route is a driving business, the vehicle and the chemicals are usually the two largest deductions, and both are easy to under-record when you are moving between eight or ten stops a day. Getting them on paper is where most of the tax savings hide.

What can a pool service business write off on taxes?

You can deduct any expense that is ordinary and necessary to service pools. That includes chlorine, acid, algaecide, and other chemicals, test kits and reagents, nets, poles, brushes, vacuums, and replacement pump and filter parts, the service van and its fuel and repairs, uniforms and safety gear, a state contractor or pesticide-application license, business insurance, phone and route-scheduling software, and advertising. Each deduction needs a record showing the amount, date, place, and business purpose, which is why the kept receipt protects the write-off and a bank statement usually does not.

Are pool chemicals a supply or cost of goods sold?

It depends on how you bill. If chemicals are consumed as part of the service and included in a flat monthly fee, they are usually deductible supplies on Schedule C. If you separately sell and deliver chemicals, salt, or equipment to customers as products, that inventory belongs in Part III cost of goods sold rather than Part II supplies. The split matters because cost of goods sold reduces gross profit before your operating expenses apply, so keep the itemized receipts that let you assign each purchase correctly.

Can I deduct the service van and mileage?

Yes. The van you drive between pools is deductible, and because a route business logs heavy miles, the vehicle is often the single biggest write-off. You choose one method per vehicle: the standard mileage rate, 72.5 cents per mile for 2026, with a log of date, miles, and purpose, or the actual-expense method that totals fuel, repairs, insurance, and depreciation on the business-use share. A dedicated work truck used entirely for the business may also qualify for Section 179 in the year you buy it. Because a route means constant driving, a mileage and expense tracker that pairs the log with your fuel and parts receipts keeps the largest deduction defensible.

What is the business code for a pool service on Schedule C?

Most pool cleaning and maintenance businesses use NAICS code 561790 (other services to buildings and dwellings) in Box B of Schedule C. A business that mainly builds or resurfaces pools would instead use a construction code. Pick the one that matches the bulk of your work. The code does not change your deductions; it should simply reflect what you actually do.

Can pool technicians deduct tools and equipment?

Yes. Vacuums, telescoping poles, nets, brushes, testing meters, cordless drills, and replacement pump or filter parts are deductible, either expensed in the year you buy them or, for larger equipment, through Section 179. Smaller consumables like brushes and test reagents are ordinary supplies deducted right away. Keep the invoices for the bigger equipment, since a full first-year Section 179 deduction has to be substantiated.

Do pool service businesses get the 20% QBI deduction?

Usually, yes. The qualified business income deduction lets many self-employed people deduct up to 20% of net business profit, and it phases out above the income thresholds only for specified service trades. Pool cleaning and maintenance is a manual service business, not consulting, law, or health, so it is generally not a specified service trade. That means most independent pool techs keep the full 20% deduction, subject to the wage and property limits above the threshold. If your income is high, confirm the classification with your preparer.

How much self-employment tax does a pool tech pay?

Self-employment tax is 15.3% on 92.35% of your net profit: 12.4% for Social Security up to the annual wage base, plus 2.9% for Medicare with no cap. You pay it on top of income tax, so setting aside roughly a quarter to a third of profit is sensible. Two things soften it: you deduct half of the self-employment tax on your return, and every legitimate business deduction lowers the net profit the tax is figured on. Most pool service owners also owe quarterly estimated taxes rather than one April payment.

How do pool service businesses win more accounts?

A pool route grows on density: the more accounts you can service on one drive, the more each mile of fuel earns. Winning new pools in the neighborhoods you already cover is the cheapest growth there is, and many operators now put their local lead generation on autopilot with an AI media buyer that runs the local ad campaigns instead of guessing at flyers. Keep the advertising spend as a deduction while you are at it.

How should a pool service keep records for taxes?

Keep a digital copy of every receipt and a running total per category, updated weekly instead of rebuilt in April. Photograph the chemical and parts receipts at the supply house, save emailed invoices to a folder, and keep a mileage log for the route. Then turn the pile into a categorized spreadsheet a preparer can use. A self-employed expense tracker that reads receipts and exports Schedule C categories does the data entry for you, and a Schedule C expense tracker lines the totals up with the deduction lines you file. Keep records at least three years from filing, longer for equipment you depreciate.

None of this replaces advice from a tax pro who knows your numbers, but the habit that makes it work is the same: capture the receipt when you spend, and let the categories build as you go.
