How to File

1

Choose a Partnership Name

Select a business name for your partnership and verify it is not already in use by searching the Idaho Secretary of State business name database. General partnerships are not required to include any specific suffix, but the name must be distinguishable from existing registered entities.

30 minutes

2

Draft a Partnership Agreement

Create a written partnership agreement outlining each partner's roles, contributions, profit and loss sharing, decision-making authority, and procedures for adding or removing partners. While not legally required by Idaho law, a partnership agreement is strongly recommended to prevent disputes.

2-5 hours

3

Obtain an Employer Identification Number (EIN)

Apply for a federal EIN from the IRS, which is required for tax filing purposes, opening a business bank account, and hiring employees. You can obtain an EIN instantly online through the IRS website at no cost.

15-30 minutes

4

File Optional Statement of Partnership Authority

Although not required, you may optionally file a Statement of Partnership Authority with the Idaho Secretary of State for $20 to establish public notice of the partnership and define partner authority to bind the partnership in transactions.

30 minutes

What's Next After Filing

Once your Partnership is officially formed, you'll want to complete these important steps:

  • Register for Idaho State TaxesRegister with the Idaho State Tax Commission for applicable taxes, including sales tax, withholding tax if you have employees, and any other applicable business taxes. You can register online through the Idaho Business Registration system.
  • Obtain Required Business Licenses and PermitsResearch and obtain any necessary federal, state, county, or city business licenses and permits required for your specific industry or location. Idaho does not have a general statewide business license, but many municipalities and professions require specific permits.
  • Open a Business Bank AccountOpen a dedicated business checking account using your EIN and partnership documentation to keep personal and business finances separate. This is critical for maintaining clear financial records and demonstrating the legitimacy of your business.

Advantages

  • Simple and inexpensive to form — no mandatory state filing fee or registration required in Idaho
  • Pass-through taxation avoids double taxation; profits and losses flow directly to partners' personal tax returns
  • Flexible management structure with no required formalities such as annual meetings or minutes
  • No annual report or franchise tax obligations in Idaho, reducing ongoing compliance costs

Considerations

  • Unlimited personal liability — each partner is personally liable for the debts and legal obligations of the partnership, including actions of other partners
  • Partners are jointly and severally liable for partnership debts, putting personal assets such as homes and savings at risk
  • No perpetual existence — the partnership may dissolve upon the death, withdrawal, or bankruptcy of a partner unless the agreement provides otherwise

Annual Obligations

Report Due:No annual report required for general partnerships in Idaho
Idaho general partnerships are not subject to an annual report requirement or franchise tax at the state level. Each partner must report their share of partnership income on their individual Idaho state income tax return (Form 40). The partnership itself files an informational return (IRS Form 1065 federally; Idaho Form 65 for state). Partners pay self-employment taxes on their distributive share of income. Sales tax and payroll tax obligations must be maintained if applicable.
