Most small businesses are sole proprietorships because this type of business is the easiest and least expensive way to start a business. In fact, the IRS reports that for 2016 (the last year calculated) over 25.5 million businesses paid taxes as sole proprietors, by filing Schedule C of Form 1040. 

What is a Sole Proprietorship? 

The sole proprietorship is the oldest and simplest form of business ownership. A sole proprietorship (or “sole prop”) is a form of business in which an individual starts a business under his or her own name. It's a one-person business; if there is more than one owner, your business can't be a sole proprietorship. In a sole proprietorship, you are the business; that is, the business is not a separate entity from you.

The IRS calls a sole proprietor someone who owns an "unincorporated business by himself or herself)." That means the business isn't a corporation (or S corporation) or a single-owner limited liability company (LLC). 

Many sole proprietors work from home. This article on Starting a Home Based Business answers commonly asked questions about the additional requirements for starting your sole proprietorship from home.

How Does a Sole Proprietorship Get Started?

A sole proprietorship is unique because it's the only business that doesn't have to register with a state. All other business types - partnerships, limited liability companies, and corporations - must file a registration form with each state in which they do business.

Starting a sole prop business is fairly simple. To start a sole proprietorship, all you need to do is:

In addition, your sole proprietorship may need to register with federal or state entities (these registrations are the same for all types of businesses):

Advantages of Sole Proprietor Form

The advantages of forming a sole proprietorship include:

Easy Startup. You don't need to prepare any legal agreements because you are not in business with someone else, and you don't have to set up an elaborate business structure: no board of directors, no meetings, no minutes, no complicated accounting for shares in the business. You just start running your business. 

Control. As the sole owner of the business, you have complete control over all the operations, and you get to make all the decisions. You don't need to have a board of directors, shareholders, or other owners to answer to.

Tax Preparation and Filing. Sole proprietorship income taxes are easy to file, using Schedule C and adding the income/loss from the business to your other income on your personal tax return.

Use of Losses. Because you are including your sole proprietorship income/loss on your personal tax return, you can use any business losses to offset personal income from other sources (a spouse's salary, for example).

To take the maximum loss, you must actively participate in the business and not be just an investor.  You also need to be careful not to run up against the IRS restrictions on "hobby" businesses which generate losses for years. If you can prove your business is legitimate and not a hobby, those losses can lower your taxes.

Disadvantages of the Sole Proprietorship

The primary disadvantage of a sole proprietorship is that your personal finances and those of your business are one and the same. You as the owner are personally liable for any debts or obligations of the business. Lawsuits or creditors may be able to access your personal accounts, assets, or property if your business can't pay its bills. 

You cannot file bankruptcy for your business without filing personal bankruptcy. Filing bankruptcy your sole proprietorship means involving your personal assets. A bankruptcy case involving a sole proprietorship includes both the business and personal assets of the owners and debtors. 

For many business people, the issues of personal liability and involvement of personal assets outweigh the advantages of sole proprietorship structure. If this is the case with you, consider forming a limited liability company (LLC) or corporation.

Getting Business Insurance Protection

You can't protect your personal assets if your business is in trouble financially, but you can get some protection from liability lawsuits if you get property and liability insurance. You will probably have to get this insurance specifically for your business, but it can help protect you if your business is involved in a liability lawsuit.

If you drive your car for business, you might want to get business auto insurance to cover you while on business trips. Most personal auto policies won't cover business driving.

Taxes and Sole Proprietorships

The sole proprietor pays federal and state income taxes on all of the net income of the business (income minus deductions), even if you don't have cash in hand to pay these taxes.

Your business income is included with your personal income on your personal tax return. The tax rate you pay may on the business income is hard to determine, since it's all combined. The corporate tax rate is a flat 21% for all corporate income levels, so your tax rate may be higher or lower, depending on your personal tax rate.

Don't forget sef-employment tax. Sole proprietors must pay self-employment tax on the profits of their business, for Social Security and Medicare. Since this tax isn't withheld from your business income, you'll probably need to make quarterly estimated tax payments for this tax and your business income tax.

The IRS publishes a Tax Guide for Small Business, which you might find helpful in dealing with federal taxes.

Check with Tax and Legal Professionals

Even if you have a very small one-person business, you should check with your tax and legal advisors before settling on a business form. There may be other things you need to consider before you start a sole proprietorship business.
