Contract labor on Line 11 of Schedule C
Contractor payments are usually an agency's single largest expense, and they are deductible in full. The freelance media buyer running client ad accounts, the designer on a monthly arrangement, the white-label SEO or video team fulfilling under your brand, the overseas VA handling reporting decks: every dollar you pay them for services reduces your taxable profit dollar for dollar.
For a sole proprietor or single-member LLC, these payments go on Line 11 of Schedule C, the contract labor line. Partnerships and S corps deduct the same payments on Form 1065 or Form 1120-S. Either way the effect is identical: an agency billing $500,000 that pays $280,000 to contractors is taxed on the margin, not the top line. Deduct the payments in the year you actually pay them if you are cash basis, which most independent agencies are.
W-9s before the first payout
The deduction is easy; the paperwork discipline is what protects it. Before a contractor's first payment, collect Form W-9, which gives you their legal name, tax ID, and entity type. You will need it in January, because payments of $600 or more in a year to an unincorporated US contractor require you to file Form 1099-NEC, with copies to the contractor and the IRS.
Foreign contractors work differently: collect Form W-8BEN (or W-8BEN-E for companies) instead, and no 1099 is filed for services performed outside the US. The payments are still fully deductible; the reporting form just changes. Pay everyone from the business bank account, keep invoices, and the deduction is bulletproof. Payments that leave no trail, cash, personal Venmo with no invoice, are the ones that get disallowed in an audit.
What does not count as contract labor
Three categories look similar but belong elsewhere. Money you pay yourself as the owner of a sole proprietorship or LLC is a draw, not contract labor, and it is not deductible at all; profit is taxed to you whether or not you withdraw it. Wages to actual employees belong on the wages line, with payroll taxes withheld and matched, not on Line 11. And purchases of things, laptops for the team, software seats, ad spend, are equipment, subscriptions, or advertising, each deductible under its own category.
The bigger structural risk is misclassification. A contractor you control like an employee, set hours, your equipment, one full-time commitment, mandatory processes for how (not just what) work gets done, can be reclassified by the IRS or a state agency, bringing back payroll taxes and penalties. Genuine contractors run their own businesses: multiple clients, their own tools, paid for deliverables. Most agency arrangements with freelancers and white-label teams sit safely on the contractor side, but agencies scaling one full-time person on contractor terms should look hard at that line before a state does.
