Are Commissions Tax Deductible?

Quick Answer: ✅ Yes — Sales commissions paid to employees, contractors, or referral partners are fully deductible as ordinary and necessary business expenses.

The Short Answer

Commissions you pay to salespeople, independent agents, brokers, or referral partners are deductible business expenses. Whether it's a 10% sales commission to your in-house rep or a finder's fee to a referral partner, it's a cost of generating revenue — and the IRS allows the full deduction.

IRS Rules for Deducting Commissions

Under IRS Publication 535 (Business Expenses) and IRC §162:

• Ordinary and necessary: Commissions are one of the most common business expenses across every industry. They're ordinary (standard practice) and necessary (directly tied to revenue generation).
• Employee commissions: Deductible as compensation expense. Must be reported on the employee's W-2. Subject to payroll taxes (Social Security, Medicare, FUTA).
• Independent contractor commissions: Deductible as contract labor or commission expense. Must issue Form 1099-NEC if you pay $600+ to a non-corporate contractor in a tax year.
• Reasonable compensation test: For closely-held businesses (especially S-Corps), the IRS scrutinizes whether commissions to owner-employees are "reasonable." Paying yourself a 50% commission while taking no salary raises red flags.
• Timing: Under the accrual method, commissions are deductible when earned (the obligation is established). Under the cash method, they're deductible when paid. For employee commissions, the "all events" test and economic performance rules under IRC §461 apply — commissions owed to employees at year-end are generally deductible only when paid within 2.5 months of year-end.

How Much Can You Deduct?

No cap on commission deductions — the amount just needs to be reasonable relative to the services provided.

How to Categorize in QuickBooks

• QBO Category: Commissions & Fees (employee) or Contract Labor (independent contractor)
• Schedule C Line: Line 10 — Commissions and Fees (for non-employee commissions) or Line 26 — Wages (for employee commissions, combined with salary)
• Tip: Separate employee commissions from contractor commissions in QBO. Use "Commissions — Employees" and "Commissions — Contractors" sub-accounts. This makes W-2 and 1099 preparation dramatically easier at year-end.

Common Mistakes to Avoid

1. Not issuing 1099-NECs. If you pay a contractor or referral partner $600+ in commissions during the year, you must file Form 1099-NEC by January 31. Missing this results in penalties starting at $60/form (up to $310/form if filed after August 1 or not at all).
2. Misclassifying employees as contractors. If your commission-based salesperson works set hours, uses your tools, and only sells for you — they're probably an employee, not a contractor. Misclassification triggers back payroll taxes, penalties, and interest.
3. Accrued commissions not paid within 2.5 months. If you accrue a commission for an employee in December but don't pay it until April, you can't deduct it in the prior year. Pay it by March 15 to get the deduction in the year it was earned.

Record-Keeping Requirements

• Commission agreements or contracts showing rates, terms, and payment schedules
• Payment records (payroll records for employees, check/ACH records for contractors)
• Sales reports tying commissions to specific transactions
• W-2s (employees) and 1099-NECs (contractors) copies
• Retain records for at least 4 years for employment tax records (IRS recommends 4 years for payroll; 7 years is safest)

Who Can Deduct Commissions?

• Sole proprietors: Deduct on Schedule C, Line 10 (Commissions and Fees) or Line 26 (Wages).
• LLCs: Deductible as a business expense on the appropriate return.
• S-Corps & C-Corps: Deductible on the corporate return. Owner-employee commissions subject to reasonable compensation rules.
• Partnerships: Deductible on Form 1065. Guaranteed payments to partners are different from commissions — consult a tax advisor.
• Nonprofits: Deductible as an operational expense. Fundraiser commissions should be disclosed per state charitable solicitation laws.
