Schedule C for Cleaning Business Owners: Line-by-Line Guide

Schedule C (Profit or Loss From Business) is the tax form that sole proprietors and single-member LLC owners use to report their cleaning business income and deductions. It's one page, but every line matters. An error on Line 9 (car expenses) or a missed deduction on Line 27a (other expenses) directly affects your tax bill.

This guide walks through every relevant Schedule C line for a cleaning business operator: what goes there, what doesn't, and the most common mistakes.

Part I: Income

Line 1: Gross receipts or sales: Report all revenue received from cleaning services during the year. For cash-basis taxpayers (the default), this is the amount received, not billed. If you invoiced $200,000 but collected $185,000, report $185,000.

Line 2: Returns and allowances: Credits, refunds, or discounts given to clients. Most cleaning businesses have minimal or zero entries here.

Line 3: Subtract Line 2 from Line 1: Your net receipts.

Line 4: Cost of goods sold: Most cleaning businesses do not have a significant COGS figure. If you sell cleaning supplies directly to clients (not for use in providing services, but as resale), that product cost goes here using Part III. If you use supplies to provide services, they're typically deducted in Part II as supplies.

Line 7: Gross income: After subtracting COGS.

Part II Expenses: The Critical Section for Cleaning Operators

Line 8: Advertising: All marketing spend: Google Ads, Facebook Ads, mailers, door hangers, yard signs, website fees. Do not include the cost of building your website here if it was a capital expense; instead, depreciate it or use §179.

Line 9: Car and truck expenses: Choose ONE method:

• Standard mileage rate: $0.67/mile for business miles in 2024. Report total business miles on lines 44a–44c (Part IV). Don't mix methods: if you used actual expenses for this vehicle in any prior year, you cannot switch to standard mileage.
• Actual expenses: Report the deductible portion of gas, oil, repairs, insurance, registration, and depreciation on this line, after multiplying by business-use percentage.

Line 10: Commissions and fees: Payments to referral partners, sales agents, or platform fees (Thumbtack, Angi, etc. referral fees). Also bookkeeping service fees and payroll processing fees if those aren't separately listed.

Line 11: Contract labor: Payments to 1099 independent contractors. This is often a large line for cleaning businesses. Remember: if these workers should have been classified as employees, this line will be scrutinized.

Line 12: Depletion: Not applicable for cleaning businesses.

Line 13: Depreciation: If you're using regular MACRS depreciation (rather than §179 or bonus), attach Form 4562. For most cleaning operators, Section 179 or bonus depreciation handles this, and the Form 4562 is still required.

Line 14: Employee benefit programs: Costs of group health insurance for employees, employer contributions to employee retirement plans. Does not include your own health insurance as owner.

Line 15: Insurance: All business insurance premiums: general liability, commercial auto, workers' compensation, janitorial bonds, umbrella. Do NOT include your personal health insurance premium here (that's an above-the-line deduction on Schedule 1).

Line 16: Interest:

• Line 16a: Mortgage interest on business real property
• Line 16b: Other business interest: vehicle financing interest (business-use portion), equipment financing interest, business line of credit interest

Line 17: Legal and professional services: Attorney fees, CPA fees, and bookkeeper fees related to the business. Note: fees specifically for tax preparation are deductible on Schedule C (for the business portion); personal tax prep fees are no longer deductible under TCJA.

Line 18: Office expense: Postage, small office supplies, business cards, pens, printer ink. Not computers or office furniture (those are capital expenses).

Line 19: Pension and profit-sharing plans: Employer contributions to employee retirement plans (not your own contributions as owner-employee: your SEP-IRA or Solo 401(k) contributions are above-the-line deductions on Schedule 1).

Line 20: Rent or lease:

• Line 20a: Vehicles, machinery, equipment: van lease payments, equipment rental
• Line 20b: Other business property: storage unit, small office space

Line 21: Repairs and maintenance: Repairs to cleaning equipment, vehicle maintenance (if using actual expense method), minor building repairs to business property.

Line 22: Supplies: Cleaning chemicals, microfiber towels, mop heads, trash liners, PPE, and other consumable supplies used in performing services. This is typically the largest line for most cleaning operators.

Line 23: Taxes and licenses: State/local business taxes, payroll taxes (employer FICA match), business licenses, annual LLC fees. Note: federal income taxes and self-employment taxes are NOT deductible here.

Line 24: Travel and meals:

• Line 24a: Travel: airfare, hotel, rental car for genuine business travel (visiting out-of-town clients, industry conferences). Must be away from your tax home overnight.
• Line 24b: Meals: 50% of business meals with clients, prospects, or employees. Entertainment is 0% deductible since TCJA 2017.

Line 25: Utilities: Electric, gas, and internet for a business location. If you use home internet for business, deduct only the business-use percentage. Home utilities are handled through the home office deduction (Line 30), not here.

Line 26: Wages: Total W-2 wages paid to employees (do not include your own "salary" as a sole proprietor; you don't pay yourself wages on Schedule C; you take draws).

Line 27a: Other expenses: This catch-all line is where cleaning operators often miss deductions:

• Business bank account monthly fees and credit card merchant processing fees
• Professional association dues (ISSA, BSCAI, chamber of commerce)
• Software subscriptions (Jobber, QuickBooks, scheduling software, CRM)
• Cell phone business-use portion
• Uniforms (if not suitable for everyday wear)
• Training and continuing education
• Background check fees for employee hiring

Line 28: Total expenses: Sum of Lines 8–27a.

Line 30: Expenses for business use of home: Enter the home office deduction here: either the simplified method ($5/sq ft, up to $1,500) or the Form 8829 calculated amount.

Line 31: Net profit or loss: Line 7 minus Line 28 minus Line 30. This is the number that flows to:

• Schedule 1, Line 3 (business income/loss on your 1040)
• Schedule SE, Line 2 (self-employment tax calculation)

Part III: Cost of Goods Sold

Complete Part III only if you sell products (cleaning supplies or chemicals as retail sales), not for supplies used in providing services. Most residential and commercial cleaning businesses can leave Part III blank.

Part IV: Vehicle Information

Required for any vehicle expense claimed on Line 9. Report:

• 44a: Total business miles during the year
• 44b: Commuting miles (not deductible)
• 44c: Other personal miles
• 44d: Whether you have written evidence (mileage log): check Yes or No
• 44e: Whether the evidence is written (yes)

The IRS uses Part IV to cross-check vehicle claims. Checking "No" on written evidence is an audit risk; if you don't have a mileage log, start one immediately.
