Does an LLC save taxes on a side hustle?

By default, no. A single-member LLC is taxed exactly like a sole proprietorship: the profit flows to your personal return and self-employment tax applies. Some LLCs later elect S corporation treatment, which can change the math at higher profit levels, but that is a separate election with payroll obligations, not an automatic benefit of forming.

Can I write off more expenses with an LLC?

No. Business expense deductions follow from having a business, not from the entity. A sole proprietor deducts the same ordinary and necessary expenses on Schedule C that a single-member LLC owner does.

Is a $0 LLC really free?

The $0 covers the service's labor for the bare filing. You still pay the state filing fee, any state franchise tax each year, and typically add-ons if you want the registered agent, operating agreement, or EIN handled. The recurring state costs are the part the ads skip.

What happens if I form an LLC and abandon the side hustle?

The obligations do not stop on their own. Annual reports and franchise taxes keep accruing until you formally dissolve, and unpaid ones bring late fees and administrative dissolution. If you wind down, file the dissolution paperwork; it is usually cheap. Compare Formation Services →

Do You Need an LLC for a Side Hustle? An Honest Decision Guide

What an LLC actually does

One thing, mainly: it separates the business's debts and legal liabilities from your personal assets. If the business is sued or cannot pay its debts, a properly maintained LLC generally keeps the claim away from your house and savings. That separation is real, but it is not magic: it does not protect you from your own professional negligence, personal guarantees you sign, or liabilities you would have anyway.

What an LLC does not do by default: lower your taxes. A single-member LLC is a disregarded entity to the IRS. The income lands on your personal return on Schedule C exactly as it would without the LLC, self-employment tax included. Tax elections that change this exist, but they are separate decisions with their own tradeoffs, not something the $0 formation button does for you.

What it costs, honestly

The formation service's price is the small number. The state's numbers are the ones that matter, and they vary wildly: forming runs from $35 in Montana to $500 in Massachusetts, and the recurring cost runs from zero in several states to an $800 annual franchise tax in California that is owed whether or not the business makes a dime. Our LLC costs by state table has every state's filing fee, report fee, and the franchise taxes, verified against the official fee schedules.

Add the optional layer: a registered agent service at $125 to $249 per year if you do not serve as your own, and whatever the formation service upsells. A California side hustle inside an LLC costs at least $820 a year before it earns anything; a Missouri one can cost $50 once and nothing after.

When the LLC starts earning its keep

Real liability exposure. You are doing physical work on other people's property, selling products that could injure someone, or giving advice businesses rely on.
Contracts and clients that require it. Some companies will not onboard unincorporated vendors; an LLC (plus an EIN) is the standard fix.
The income is no longer pocket money. As revenue grows, so does what a claimant could come after, and so does the value of clean business-personal separation, including a dedicated bank account.
A partner joins. Two people sharing revenue without an entity and an operating agreement is a dispute waiting for a courtroom.

When it can wait

Low-risk service work with modest income often has a cheaper, better protection: insurance. A general liability or professional liability policy pays claims; an LLC only contains them. Plenty of freelancers carry a policy for a few hundred dollars a year and form the LLC later, when a client requires it or the income justifies it. If your side hustle is selling crafts, tutoring, or freelance writing measured in hundreds of dollars a month, the state franchise tax can exceed the risk you are containing.

If you do form one, the order of operations

Check your state's real costs first, formation and recurring, on the state table. Form in your home state unless you have specific advice otherwise; forming elsewhere usually means paying two states.
Decide the registered agent question: serving as your own is free and legal in most states if you have an in-state street address and do not mind it becoming public record.
Get the EIN directly from the IRS. It is free at irs.gov; paying a service $99 for it buys you a form-filler.
Open a separate bank account and keep it clean. Mixing personal and business money is the classic way courts justify ignoring the LLC when it matters most.
