Question 1

How is side hustle income taxed?

Accepted Answer

Side hustle income faces double taxation: (1) Self-employment tax: 15.3% (12.4% Social Security + 2.9% Medicare) on 92.35% of net profit, (2) Income tax: ordinary income rates (10-37%) based on your total income. Combined, you may pay 25-50% depending on your bracket. You can deduct business expenses to reduce taxable income.

Question 2

What is self-employment tax?

Accepted Answer

Self-employment tax is the self-employed equivalent of FICA (Social Security and Medicare) taxes. The total rate is 15.3%: 12.4% Social Security (on earnings up to $176,100 in 2025) and 2.9% Medicare (unlimited). Unlike W-2 employees where employers pay half, self-employed individuals pay both halves. You can deduct 50% of SE tax as an adjustment to income.

Question 3

Do I need to pay quarterly estimated taxes?

Accepted Answer

Yes, if you expect to owe $1,000+ in taxes. The IRS requires quarterly estimated tax payments on April 15, June 15, September 15, and January 15. Underpayment can result in penalties. To avoid penalties, pay 90% of current year tax or 100% of prior year tax (110% if AGI over $150,000). Use Form 1040-ES.

Question 4

What side hustle expenses can I deduct?

Accepted Answer

Common deductible expenses include: (1) Home office (if exclusive use), (2) Business supplies and equipment, (3) Software/subscriptions, (4) Advertising and marketing, (5) Professional fees (legal, accounting), (6) Business mileage (67 cents/mile in 2024), (7) Phone/internet (business portion), (8) Education/training, (9) Health insurance (if self-employed). Keep detailed records.

Question 5

When do I need to form an LLC or S-Corp?

Accepted Answer

Consider an LLC for liability protection at any income level. Consider S-Corp election when net profit exceeds $60,000-$80,000 annually - it can reduce self-employment tax by paying yourself a reasonable salary (subject to SE tax) and taking remaining profits as distributions (not subject to SE tax). Requires payroll, corporate tax returns, and compliance costs.

Question 6

How do I report side hustle income?

Accepted Answer

Report side hustle income on Schedule C (Profit or Loss from Business). Calculate net profit (income minus expenses), then transfer to Form 1040. Schedule SE calculates self-employment tax. Keep records of all income and expenses. If you receive $600+ from a client, they should send Form 1099-NEC. Report all income even without a 1099.

Question 7

What is the QBI deduction for side hustles?

Accepted Answer

The Qualified Business Income (QBI) deduction allows you to deduct up to 20% of your side hustle profit. This reduces income tax (but not self-employment tax). The deduction phases out for certain service businesses (consulting, law, accounting, health) when income exceeds $191,950 (single) or $383,900 (married). Most side hustles qualify fully.

Question 8

Can I deduct a home office for my side hustle?

Accepted Answer

Yes, if you use a portion of your home exclusively and regularly for business. Two methods: (1) Simplified: $5 per square foot (max 300 sq ft = $1,500 max deduction), (2) Regular: actual expenses (mortgage interest, utilities, insurance, repairs) × business percentage. Simplified method is easier but regular method may yield larger deduction.
