Idaho LLC Taxes
Last updated:
How an Idaho LLC is taxed: federal pass-through treatment, self-employment tax, Idaho income and entity taxes, and the payments to plan for.
An Idaho LLC is taxed at three levels: federal income tax on the profits, Idaho state rules, and payroll or sales taxes that depend on what the business does. Idaho taxes personal income, so LLC owners report their share of profit on a Idaho return in addition to the federal one. Idaho does not charge a separate franchise or privilege tax on LLCs.
Federal tax treatment
By default the IRS treats a single-member LLC as a disregarded entity, so profit is reported on Schedule C of the owner's personal return. A multi-member LLC is taxed as a partnership and files Form 1065, with each member receiving a Schedule K-1. Either can elect to be taxed as an S corporation (Form 2553) or a C corporation (Form 8832). See the IRS page on LLCs.
Self-employment tax
Members who work in the business generally pay self-employment tax of 15.3% on net earnings: 12.4% for Social Security up to the annual wage base set by the SSA, and 2.9% for Medicare with no cap, plus an additional 0.9% Medicare tax at higher incomes. An S corporation election can reduce this for profitable businesses, but it requires running payroll and paying yourself a reasonable salary. Our LLC vs S-Corp comparison walks through the trade-off.
Idaho state taxes
| Tax | Idaho treatment |
|---|---|
| State personal income tax | Applies to owners' share of LLC profit |
| Franchise or entity-level tax | None |
| Annual report fee | No fee |
Sales tax, payroll tax, and local business taxes sit on top of these. If you sell taxable goods or services, register with the Idaho tax agency for a sales tax permit. If you hire, you will register for state unemployment insurance and withholding.
Estimated tax payments
LLC owners usually have no employer withholding, so they pay federal estimated tax each quarter, and Idaho estimated tax as well. Missing estimates can trigger underpayment penalties, so many owners set aside a percentage of every payment they receive.
Idaho specific notes
Idaho requires an annual report but charges no fee. Failure to file results in administrative dissolution after the grace period.
