Tips & Advice

Set aside 25-30% for taxes

As a self-employed worker, you pay both the employer and employee share of Social Security and Medicare. Set aside money from every payment.

Track every business expense

Mileage, supplies, software, home office space, and phone usage can all be deducted. Use an app to track expenses in real time.

Make quarterly estimated tax payments

If you expect to owe $1,000+ in taxes, the IRS requires quarterly payments. Missing them results in penalties.

Separate business and personal finances

Open a dedicated checking account for your side hustle. It simplifies bookkeeping and looks more professional.

Know your true hourly rate

Factor in expenses, taxes, and unpaid admin time. Your real hourly rate may be lower than you think.

Consider an S-Corp election for high earners

If your side hustle consistently earns over $40,000/year, an S-Corp election could significantly reduce self-employment tax.
