Freelancers and sole proprietors report profit or loss on Schedule C (Form 1040). Deductions reduce net profit, which feeds both income tax and self-employment tax. This checklist walks common categories with recordkeeping tips—not every item applies to every activity.

1. Core deduction categories

Category	Examples	Record to keep
Advertising	Ads, website, business cards	Invoices, payment proof
Car and truck	Mileage or actual expenses	Mileage log, gas receipts
Contract labor	Subcontractors	1099-NEC issued, contracts
Depreciation	Equipment, computers	Purchase dates, Form 4562
Insurance	Liability, E&O	Policy declarations
Legal and professional	CPA, attorney	Engagement letters
Office expense	Supplies, software	Receipts tagged by project
Rent or lease	Office, equipment	Lease agreements
Travel	Airfare, lodging for business	Agenda, receipts
Meals	Business meals (limits apply)	Who, what business discussed

2. Home office (if eligible)

Exclusive and regular business use may qualify for simplified or actual-expense methods. See our dedicated home office article for method comparison. Allocate rent, utilities, and depreciation carefully—personal use is not deductible.

3. Startup vs operating costs

Costs before the business begins may be capitalized or amortized under Section 195 rules rather than fully deducted immediately. Distinguish organizational costs from syndication costs with your CPA.

4. What is NOT deductible

• Personal living expenses and commuting to a regular workplace.
• Fines and penalties paid to governments.
• Political contributions and most club dues for entertainment.
• Expenses without business purpose documentation.

5. Numeric example

A freelance developer with $140,000 gross receipts:

Expense	Amount
Software subscriptions	$4,200
Home office (simplified)	$1,500
Mileage (2,000 mi × IRS rate)	See annual rate
Professional development	$2,800
Insurance (business liability)	$1,100
Total deductions (illustrative)	$12,000+

Net profit of $128,000 flows to Schedule SE for self-employment tax and to Form 1040 for income tax.

6. Year-round recordkeeping

1. Separate business bank account and card.
2. Accounting software with receipt capture.
3. Quarterly review—do not stack December-only entries without support.
4. Match 1099-NEC received to booked revenue.

Schedule C is the hub of sole proprietor reporting. Layer state and local taxes separately—they are not automatic in educational simulators.
