If you’re looking to start a single owner business in Iowa, a sole proprietorship is the most basic option. Starting a sole proprietorship in Iowa doesn’t require any official paperwork to be formed, however there are some other steps you’ll need to complete to ensure your business is legally compliant. In this guide we’ll cover the steps you’ll need to get your Iowa sole proprietorship up and running properly.

Liability Risk of Sole Proprietorships

Iowa businesses that operate as sole proprietors don’t have personal asset protection. For liability protection consider starting an Iowa LLC instead of a sole proprietorship. To learn more read our guide comparing LLCs vs Sole Proprietorships, which outlines the pros and cons of each.

1. Come Up with a Business Name

Initially when starting a Iowa sole proprietorship you’ll need to choose a business name. You’ll want to make sure the name you choose is unique, easy to remember, and easy to search for. For more detailed directions on choosing a business name check out our 15 tip guide where we go over what makes a great business name.

Business Name Search

Make sure you conduct 2 prelimary searches to ensure that you business name is not already in use in Iowa and hasn’t been trademarked at the federal level:

2. Register Your Business Name

As a sole proprietor, there is no legal separation between you as an individual and your business. As a result if you plan to operate under a business name other than your own personal name, you’ll need to file a DBA to register your Iowa business name. DBA stands for “doing business as” and is a way for a business to operate under a name different than their legal name. In Iowa you may also hear a DBA referred to as a “Assumed Name”.

DBA’s for sole proprietors in Iowa are filed at the county level. To complete the registration of your Iowa DBA, file a Assumed Name application with the county recorder’s office. The DBA (Assumed Name) filing fee for sole proprietors is $7 for the first page and $5 for every additional page.

3. Obtain Business Licenses and Permits

Sole proprietorships are subject to business and professional licensing requirements. Business and professional licenses are issued at the federal, state, and local levels. The types of licenses and permits your business is required to file will vary widely depending upon the nature of your business and how it operates.

Federal Licenses and Permits

Most common types of businesses are not subject to federal licensing, however if manufacture or sell products that are regulated at the federal level you will need the relevant federal license before you begin operating. Below is a list of federal agencies from the U.S. Small Business Administration (SBA) that issue federal permits and licenses :

4. Get an EIN from the IRS

If you have employees, you are required to get an EIN. EINs are a nine-digit ID number issued by the IRS to identify businesses for tax purposes. You can apply for an EIN for free online using the IRS’ EIN Assistant.

If you don’t have employees, you are not required to get an EIN as a sole proprietor. However, it can be useful to get an EIN. They are often required to open a business bank account and can be used in place of your social security number for most business applications.

Important Note about Sole Proprietor EINs:

Since sole proprietorships are not viewed as separate from an individual, sole proprietor EINs are issued under their names, not their DBA names. As a result, you will only be issued 1 EIN as a sole proprietor for your lifetime. This will be used for any and all businesses you will operate as a sole proprietor. If you apply for an EIN as a sole proprietor and receive reference error 101, this likely means that you have already been issued an EIN previously. If you cannot recall your EIN or have not been issued an EIN previously, you will need to call the IRS Business and Specialty Tax Assistance line at 1-800-829-4933 and use the prompts related to reference number 101.

5. Open a Business Bank Account

The final step to making your Iowa sole proprietorship a reality is to open a business bank account. It’s important to keep your business and personal transactions separate to prevent the co-mingling of funds. The easiest way to do this is to open a designated business bank account and use it only for business transactions. This will make it easier for you to complete your accounting and bookkeeping tasks.

Other Items to Consider

Once you have established your sole proprietorship, you will also want to complete these important tasks:

  • Setup Credit Card Processing:
    Considering that over 60% of transactions are done via debit and credit cards, it’s essentially a requirement to accept credit card payments. We go over how to do this in our How to Accept Credit Card Payments guide.

  • Establish an Accounting System:
    You’ll need to determine the accounting method you will use for your business: cash basis accounting vs. accrual accounting. To learn more, check out our guide on small business accounting 101.

  • Get Business Insurance Coverage:
    As a sole proprietor, you lack personal liability protection, so getting adequate business insurance could be your only financial protection method. Learn more about business insurance here.
