Understanding Side Hustle Tax Basics
Starting a side hustle means entering the world of business taxes. Whether you're driving for Uber, selling handmade crafts, or freelance writing, the IRS considers your side income as business income that must be reported.
When You Need to Report Side Hustle Income
You must report side hustle income if you earn $400 or more in net self-employment earnings during the tax year. This threshold is much lower than the standard filing requirement for regular employment income.
Types of Tax Forms You'll Encounter
- 1099-NEC: Received from clients who paid you $600+ for services
- 1099-K: Received from payment processors like PayPal or Square for transactions over $600
- Schedule C: Where you report your business income and expenses
- Schedule SE: Used to calculate self-employment tax
Business vs. Hobby Classification
The IRS distinguishes between businesses and hobbies based on profit motive. If you're genuinely trying to make a profit (even if you don't always succeed), you're running a business and can deduct expenses. Hobby income is still taxable, but deductions are severely limited.
Record Keeping and Expense Tracking
Proper record keeping is your foundation for accurate tax filing and maximum deductions. Without good records, you'll likely overpay taxes and struggle during an audit.
Essential Records to Maintain
Income Records:
- All 1099 forms received
- Bank statements showing deposits
- Payment app records (Venmo, PayPal, Cash App)
- Invoice copies and receipts from customers
- Cash payment logs
Expense Records:
- Receipts for all business purchases
- Bank statements showing business transactions
- Credit card statements for business expenses
- Mileage logs for vehicle use
- Home office measurements and utility bills
Digital Tracking Methods
Recommended Apps:
- QuickBooks Self-Employed: Automatically categorizes transactions
- FreshBooks: Great for invoicing and expense tracking
- Wave: Free accounting software for small businesses
- Mint: Basic expense categorization
- Shoeboxed: Receipt scanning and organization
Manual Tracking System
If you prefer paper records:
- Create separate folders for income and expenses
- Use a mileage log book for vehicle expenses
- Maintain a simple spreadsheet with date, amount, and business purpose
- Take photos of receipts as backup
Business Deductions You Can Claim
Business deductions reduce your taxable income, potentially saving hundreds or thousands in taxes. Here are the most common deductions for side hustlers:
Home Office Deduction
If you use part of your home exclusively for business, you can claim this valuable deduction.
Simplified Method:
- Deduct $5 per square foot (up to 300 sq ft)
- Maximum deduction: $1,500 annually
- No depreciation calculations required
Actual Expense Method:
- Calculate percentage of home used for business
- Deduct that percentage of mortgage interest, utilities, insurance, repairs
- More complex but potentially larger deduction
Vehicle Expenses
Standard Mileage Rate (2024): 67¢ per mile
