The IRS classifications described in this article are based on general tax principles and may vary depending on your specific circumstances.
Why Platform Fee Classification Matters for Freelancers
If you earn income through freelance platforms like Upwork, Fiverr, or payment processors like Stripe, you are no stranger to platform fees. Upwork automatically deducts 10-20% when you get paid. Stripe charges 2.9% + $0.30 per transaction. PayPal, Wise, Square, and dozens of other platforms each take their cut.
The question is: Where do these fees belong on your IRS Schedule C? Should they go under "Other Expenses" or another category? Incorrect classification may lead to questions from the IRS. Correct classification maximizes your deductions.
For 2026 freelancer taxes, understanding platform fee classification is more important than ever. With the freelance economy growing and IRS scrutiny increasing on gig economy deductions, accurate classification protects you during audits while ensuring you claim every legitimate deduction you're entitled to.
This guide references IRS Schedule C Instructions (2025) for Line 11, Line 8, and Line 27 classifications. These classifications remain current for tax year 2026 filing.
This guide explains exactly how to categorize and classify fees from every major freelance platform so you can claim the proper tax deduction for your business expenses.
Understanding the Relevant Schedule C Line Items
Before classifying platform fees, you need to understand what each Schedule C line item covers and why certain fees don't belong in specific categories.
Commissions and Fees (Line 11)
According to IRS Schedule C Instructions (2025), Commissions and Fees (Line 11) cover "commissions and fees paid to employees or agents who sell your products or services." This includes both internal employees and external sales agents or brokers who are paid specifically to generate sales. See IRS Schedule C Instructions (2025), Line 11 - Commissions and Fees, page 12.
Why platform fees don't fit here:
- This line is for commissions you pay to employees or contracted sales representatives who directly sell your services—including third-party agents or brokers who actively market your services
- Upwork and Fiverr are not your employees or sales agents—they are third-party marketplaces that provide a platform for connecting with clients, not for actively selling your services
- The fee is a cost of doing business, not a commission tied to individual sales performance by a representative
When this line DOES apply:
- If you pay an employee or contractor a percentage of each sale they generate specifically
- Referral fees paid to individuals or agencies who actively bring you clients (not platform fees)
- Commissions paid to sales agents who represent your business
Advertising (Line 8)
Advertising expenses (Line 8) promote your business to attract customers. According to IRS Schedule C Instructions, this includes costs for advertising in newspapers, online ads, radio, television, and business directories. See IRS Schedule C Instructions (2025), Line 8 - Advertising, page 10.
Why platform fees don't fit here:
- Stripe, PayPal, and Upwork do not advertise your business—they process payments or facilitate transactions
- While you might find clients through Upwork or Fiverr, the fee is not for advertising services
- The IRS specifically distinguishes between finding clients (not advertising) and promoting your services
When this line DOES apply:
- Google Ads, Facebook/Meta advertising costs
- Website hosting fees (if primarily for marketing)
- Promotional materials, business cards, brochure printing
Other Expenses (Line 27)
Other Expenses (Line 27) is a catch-all category for legitimate business costs that do not fit neatly into other Schedule C line items. According to IRS Schedule C Instructions, this includes various expenses that are ordinary and necessary for your business operations. See IRS Schedule C Instructions (2025), Line 27 - Other Expenses, page 26-27.
Why platform fees belong here:
- Platform fees are operational costs that facilitate business income but don't match any specific Schedule C category
- Both marketplace platforms (Upwork, Fiverr) and payment processors (Stripe, PayPal) charge fees for transaction processing—not for advertising or sales commissions
- IRS expects documentation showing why fees don't fit other categories
Important for 2026: IRS scrutinizes unusually high "Other Expenses" claims, so maintain detailed records explaining the business purpose of each fee type. For tax year 2026, with increased IRS focus on gig economy deductions, proper documentation is more critical than ever.
Complete Platform-by-Platform Fee Classification Guide
Upwork: Marketplace Fee Classification
Upwork is the largest freelance marketplace. Their fee structure:
- First $500 billed: 20% service fee
- $500.01 - $10,000: 10% service fee
- Over $10,000: 5% service fee
Upwork deducts these fees automatically from your earnings.
IRS Classification: Other Expenses (Line 27)
Upwork is a marketplace platform that connects freelancers with clients. While their fee facilitates transactions, IRS classifies these fees under Other Expenses since they do not fit neatly into other Schedule C categories.
Stripe: Payment Processing Fee Classification
Stripe is the preferred payment processor for freelancers with their own websites. Fee structure:
- Domestic cards: 2.9% + $0.30 per transaction
- International cards: 3.9% + $0.30 per transaction
- ACH Direct Debit: 0.8% (capped at $5)
IRS Classification: Other Expenses (Line 27)
Stripe is a payment processor that enables you to accept client payments on your own website. Payment processing fees are generally deductible business expenses and belong in Other Expenses.

Fiverr: Marketplace Fee Classification
Fiverr works similarly to Upwork. Fee structure:
- Service price: 20% fee (deducted from your earnings)
IRS Classification: Other Expenses (Line 27)
Like Upwork, Fiverr is a marketplace platform. Their fees are classified under Other Expenses since they do not fit into other Schedule C categories.
PayPal: Payment Processing Fee Classification
PayPal has been the standard for online payments. Fee structure:
- Domestic transactions: 2.9% + $0.30 per transaction
- International transactions: 4.4% + fixed fee (varies by country)
- Currency conversion: Additional fees apply
IRS Classification: Other Expenses (Line 27)
Payment processing and bank fees are generally deductible business expenses and belong in Other Expenses.
Wise (TransferWise): International Transfer Fee Classification
Wise offers low-cost international transfers for freelancers with overseas clients.
IRS Classification: Other Expenses (Line 27)
International wire transfer fees related to business income go in Other Expenses.
Mixed Business Models: When You Use Multiple Platforms
Many freelancers use both marketplaces AND their own websites. How do you classify fees then?
The Rule: All platform fees—whether from marketplaces or payment processors—go in Other Expenses (Line 27).
Example Scenario: Sarah is a graphic designer who gets 60% of her clients through Upwork and 40% through her own website using Stripe. She classifies all her platform fees under Other Expenses (Line 27). Sarah maintains a spreadsheet tracking which platform each payment came from, making it easy to categorize fees correctly at tax time.
IRS expects you to categorize expenses based on their specific purpose. Since neither Upwork nor Stripe fees fit neatly into Schedule C's specific categories, Other Expenses is the appropriate classification for both.
Platform fees are just one category of deductions. Check out our guide to top 15 tax deductions for 1099 contractors to discover other expenses you may be able to deduct.
Practical Tips for Platform Fee Deductions
1. Download Annual Fee Reports
Every platform provides annual statements:
- Upwork: Go to Reports > All Earnings
- Stripe: Dashboard > Balance > Statements
- PayPal: Account Settings > Statements
Tip: Download your annual statements before tax season to ensure you have everything ready when filing.
2. Track Fees Separately by Platform
Maintain a spreadsheet categorizing fees by platform and their Schedule C line item.
3. Convert Foreign Currency to USD
For international platforms, record the exchange rate at the time of each transaction. IRS requires USD reporting using the exchange rate on the transaction date.
4. Document the Business Purpose
Keep records explaining why each fee qualifies as a deduction. This documentation protects you during IRS audits.
5. Consider Quarterly Estimated Taxes
As a freelancer in 2026, you're responsible for paying self-employment tax alongside your income tax. Platform fees reduce your taxable income, which affects your quarterly estimated tax payments.
2026 Quarterly Tax Deadlines:
- Q1 2026 (Jan-Mar): Due April 15, 2026
- Q2 2026 (Apr-May): Due June 15, 2026
- Q3 2026 (Jun-Aug): Due September 15, 2026
- Q4 2026 (Sep-Dec): Due January 15, 2027
Understanding how these deductions work can help you plan more accurately throughout the year.
