Idaho LLC Cost (2026): Complete Breakdown of Every Fee

This page breaks down every cost of forming and maintaining a Idaho LLC in 2026: the one-time state filing fee, the mandatory annual costs, optional and situation-specific fees, and the true three-year total under each formation option. Every figure is drawn from the Idaho Secretary of State and cross-checked against our Idaho LLC formation guide.
Idaho is one of the lower-maintenance states for LLC owners: Idaho's annual report is free, so there is no recurring state filing fee, though the report is still mandatory each year. That keeps the true ongoing cost near zero for a typical small pass-through LLC.
Idaho LLC costs at a glance: the three figures below highlight this state's key numbers: the one-time state filing fee plus the main ongoing state fees or taxes. Each is explained in full in the sections that follow.

| Annual report | $0 (free, mandatory) | anniversary month | Filed with the Idaho Secretary of State |
| Late annual report penalty | administrative dissolution if not filed | After deadline | Avoid by filing on time |
| State income tax | Varies | Annual | Paid on your personal return for pass-through LLCs |
| Franchise / special tax | See notes | Varies | None |
| Annual minimum (DIY, no RA service) | $0 | Varies | Idaho's annual report is free, so there is no recurring state filing fee, though the report is still mandatory each year |

True 3-Year Total Cost Comparison
The formation fee is paid once. What actually determines your LLC's affordability is the total cost over the years you operate it. Here is the 3-year total under each formation option .
| Scenario | Year 1 | Year 2 | Year 3 | 3-Year Total |
|---|---|---|---|---|
| Northwest Registered Agent | $139 ($100 state + $39 service, RA free) | $125 ($0 state min + $125 RA) | $125 | $389 |
| ZenBusiness (Starter) | $199 ($100 state + $0 service + $99 RA) | $199 ($0 state min + $199 RA) | $199 | $597 |
| DIY, self as registered agent | $100 (filing) | $0 (state minimum) | $0 | $100 |
Finding: Over three years, the difference between DIY (self as agent) and Northwest Registered Agent is $289. That covers registered agent service, keeping your home address off the public record, and compliance reminders so you never miss a filing deadline. For most owners who do not want their home address public, that is a worthwhile trade.
Optional and Situation-Specific Costs
These costs apply only in specific situations. Exact amounts vary; verify current fees with the Idaho Secretary of State before filing.
| Cost Item | Typical Amount | When You'd Pay This |
|---|---|---|
| Certified copy of formation documents | $10 to $50 | Some banks and contracts require one |
| Certificate of Good Standing | $10 to $50 | Required for foreign registration or financing in other states |
| Registered agent change | $0 to $25 | When switching registered agents |
| Amendment to formation documents | $25 to $100 | Changing LLC name, address, or other formation details |
| DBA / trade name registration | $10 to $50 | Operating under a name different from your LLC name |
| Expedited processing | Varies by state | When you need faster approval than standard processing |
| Dissolution filing | $0 to $100 | When formally closing the LLC |
| Local business license | $50 to $500/year | Varies by city/county; many localities require one |

When a Idaho LLC Is Not Worth the Cost
An LLC is a great fit for many businesses, but there are situations where the cost outweighs the benefit:
- Pre-revenue or very low-revenue side project: If your business earns little, the annual state costs and any registered agent fee are pure overhead. Operating as a sole proprietor is free until the business is generating real income.
- You plan to keep the LLC dormant: A Idaho LLC with no activity still owes its ongoing state costs until it is formally dissolved. Dormant LLCs accumulate fees and risk administrative dissolution if a filing lapses.
- You are not actually in Idaho: Forming here when your business operates elsewhere adds compliance costs and often a second registered agent fee with no benefit. Form in the state where you actually do business.
