Why Side Hustle Income Is Taxed Differently

Nothing is withheld from side-hustle income, and self-employment tax is separate from regular income tax. Setting money aside as you earn makes the eventual bill visible before it is spent.

The 25–30% Rule

Many US side hustlers use a planning set-aside of 25% to 30% of profit; higher earners or people in states with income tax may need more. This is a planning rule, not personal tax advice.

Set Aside On Profit, Not Revenue

Net platform fees and legitimate business expenses first, then set aside a percentage of what remains.

Quarterly Estimated Payments

If you expect to owe $1,000 or more, estimated tax payments may be required. Check current IRS Form 1040-ES instructions and due dates.
