Pick a structure
Most owners choose an LLC or a corporation; the S corp or C corp tax choice comes later. See Idaho LLC guide, Idaho corporation guide, S corp or C corp in Idaho. By trade: cleaning business, handyman.
Check and register the name
Search the Secretary of State records before you pick a name: state name search. The Idaho Secretary of State registers assumed business names, and its paper Certificate of Assumed Business Name lists a $25 base filing fee plus a $20 manual processing fee, $45 in total. 1 See Idaho name search guide.
File with the state
Idaho charges the state filing fee once: an LLC costs $103 2 and a corporation's articles of incorporation cost $100 3. See LLC cost.
Name a registered agent
An Idaho corporation must designate and maintain a registered agent in Idaho, and the address in the filing must be a street address in Idaho. 4 Our registered agent service runs through our partner Registered Agents Inc (RAI), the registered agent of record. See Idaho registered agent rules.
Which accounts do you open after you file in Idaho?
Get an EIN
An EIN is the business's federal tax ID. The IRS issues it online, for free, and warns about websites that charge for one. 5
Open your state tax accounts
The Idaho State Tax Commission requires businesses to register for certain tax permits, including seller's permits, through the Idaho Business Registration process, and employers also get an income tax withholding account. 6 See Sales tax permit.
Register as an employer
The Idaho Department of Labor taxes employers that paid $1,500 or more in wages in a calendar quarter or had workers in 20 different weeks, and its registration form is due within six months of becoming a covered employer. 7 Idaho employers report each new employee to the Idaho Department of Labor within 20 days of the date of hire. 8 The Idaho Industrial Commission requires workers' compensation coverage for employers with one or more full-time, part-time, seasonal or occasional employees unless exempt; exemptions include the owner of a sole proprietorship and working members of a partnership or limited liability company. 9
