Pressure Washing Business Entity Structure: S-Corp Election, Equipment Deductions, and Non-SSTB QBI
Pressure washing is one of the fastest-growing home service businesses, with relatively low startup costs ($5,000-$15,000 for equipment) and high margins once established. The business isn’t an SSTB, meaning the full 20% QBI deduction is available at any income level with no phase-out. Combined with the S-Corp election and equipment deductions, a profitable pressure washing business can achieve a very favorable effective tax rate.
Pressure washing business tax profile:
-
NOT an SSTB. Pressure washing is a skilled trade, not consulting or any enumerated SSTB. The full 20% QBI deduction is available at any income level.
-
S-Corp break-even: $50,000-$60,000 net profit. Below that, the costs of payroll processing and the S-Corp return exceed the SE tax savings. Above that, savings grow with income.
-
Equipment deductions. Pressure washers ($1,000-$10,000), surface cleaners ($200-$1,500), chemical injection systems ($200-$500), trailers ($3,000-$10,000), water tanks, and hose reels are all depreciable business assets. Most items qualify for Section 179 immediate expensing or fall under the de minimis safe harbor ($2,500 per item).
-
Vehicle and trailer. The truck (or van) used to haul equipment is deductible. If the truck has a GVWR over 6,000 lbs, the full purchase price is deductible through Section 179 in the year of purchase. The trailer is a separate asset, also eligible for Section 179.
-
Chemical costs. Soft wash chemicals (sodium hypochlorite, surfactants), downstream injection chemicals, and cleaning solutions are ordinary business expenses deducted when purchased. For a busy operator, chemical costs run $3,000-$8,000/year.
-
Low employee threshold. Most pressure washing businesses start as owner-operated. When helpers are added, they are employees (the owner controls the schedule, provides equipment, sets the price, and directs the work). Solo 401(k) is available for owner-only operations; transition to SIMPLE IRA when employees are hired.
How does the full deduction stack work?
What happens to my business if I die without a succession plan?
Without a succession plan, your business’s fate depends on its legal structure. A sole proprietorship has no legal existence apart from you and simply ceases to exist. A single-member LLC’s operating agreement may or may not grant transfer rights to your estate. If it is silent, state default rules apply, and most states allow the interest to pass but not management rights, leaving the estate with an economic interest it cannot control. An S-Corp’s shares pass through the estate, but if the heir is an ineligible S-Corp shareholder (a nonresident alien, for example), the election terminates retroactively. A buy-sell agreement funded by life insurance is the standard solution: the policy pays out at death, and the agreement dictates who buys the interest and at what price.
