Side Hustles: When Hobby Income Needs an Entity

What to know

• Under ~$10k/yr: sole prop + separate bank account is usually rational.
• Past ~$30–50k: LLC liability shield + S-election analysis pay for themselves.
• Platform income (Etsy, Upwork, YouTube) counts toward state thresholds from dollar one.

Do you need an entity?

A side business is a sole proprietorship by default: income goes on Schedule C and pays income and self-employment tax, with no state filing. An LLC adds liability protection but, in California, costs $800 a year even if the side hustle earns $3,000. For low-risk online work under roughly $10,000 a year, a separate bank account and good records usually matter more than an entity.

Taxes still apply below 1099 thresholds

From 2026, platforms send Form 1099-K only above $20,000 and 200 transactions, and clients issue 1099-NEC only at $2,000 or more. Income below those lines is still taxable, and net self-employment earnings of $400 or more trigger self-employment tax.

When to formalize

Consider an LLC when the business has real liability exposure (clients, products, physical services), when profit reaches the point where an S election could save payroll tax, or when you want to open business accounts with payment processors in the business's name.
