Tax Basics for Freelancers: Keep More of What You Earn

Understand Self-Employment Tax

This is the surprise that hits new freelancers hard. Beyond income tax, you owe 15.3% self-employment tax on net profit—covering Social Security (12.4%) and Medicare (2.9%). Employees split this with employers, but freelancers pay both halves.

The good news: you deduct half of SE tax as an adjustment to income, and it only applies to net profit AFTER business expenses. This is why tracking deductible expenses is crucial—every legitimate deduction reduces both income tax AND self-employment tax.

Make Quarterly Estimated Payments

Unlike employees with automatic withholding, freelancers must pay taxes quarterly to avoid penalties:

• Q1: January 1 - March 31 → Due April 15
• Q2: April 1 - May 31 → Due June 15
• Q3: June 1 - August 31 → Due September 15
• Q4: September 1 - December 31 → Due January 15 (next year)

Set aside 25-30% of every payment you receive. Your tax burden is YOUR responsibility to estimate and pay—the IRS won't remind you.

Track EVERY Business Expense

Legitimate business expenses reduce taxable income dollar-for-dollar. The test: is this expense "ordinary and necessary" for your business?

• Snap photos of receipts immediately (use Expensify or similar)
• Categorize expenses weekly, not at tax time
• Note business purpose on each receipt
• Track mileage in real-time with GPS apps
• Save digital copies for 7 years minimum

Missing documentation during an audit means deductions are disallowed, resulting in significant tax bills plus penalties.

Separate Business & Personal Finances

Mixing business and personal finances creates recordkeeping nightmares and audit red flags:

• Open dedicated business checking account
• Get a business credit card
• Run ALL business income through business account
• Pay yourself via transfer from business to personal
• NEVER pay personal expenses from business account

Separation makes tax prep infinitely easier and demonstrates professionalism to the IRS. Your business account becomes your income/expense record.

Master the Home Office Deduction

If you work from home, this deduction can be significant—but rules are strict:

• Space must be used REGULARLY and EXCLUSIVELY for business
• Must be your principal place of business
• Simplified method: $5/sq ft (max 300 sq ft = $1,500)
• Actual method: percentage of rent, utilities, repairs, insurance

Document your space with photos and measurements. The home office deduction also unlocks other deductions like mileage from home office to client sites.
