The simplest structure is the sole proprietorship, which usually involves just one individual who owns and operates the enterprise. If you intend to work alone, this structure may be the way to go.
The tax aspects of a sole proprietorship are appealing because the expenses and your income from the business are included on your personal income tax return, Form 1040. Your profits and losses are recorded on a form called Schedule C, which is filed with your 1040. The “bottom-line amount” from Schedule C is then transferred to your personal tax return. This is especially attractive because business losses you suffer may offset the income you have earned from your other sources.
As a sole proprietor, you must also file a Schedule SE with Form 1040. You use Schedule SE to calculate how much self-employment tax you owe. In addition to paying annual self-employment taxes, you must make estimated tax payments if you expect to owe at least $1,000 in federal taxes for the year after deducting your withholding and credits, and your withholding will be less than the smaller of: 1) 90 percent of the tax to be shown on your current year tax return or 2) 100 percent of your previous year’s tax liability.
The federal government permits you to pay estimated taxes in four equal amounts throughout the year on the 15th of April, June, September and January. With a sole proprietorship, your business earnings are taxed only once, unlike other business structures. Another big plus is that you will have complete control over your business–you make all the decisions.
There are a few disadvantages to consider, however. Selecting the sole proprietorship business structure means you are personally responsible for your company’s liabilities. As a result, you are placing your assets at risk, and they could be seized to satisfy a business debt or a legal claim filed against you.
Raising money for a sole proprietorship can also be difficult. Banks and other financing sources may be reluctant to make business loans to sole proprietorships. In most cases, you will have to depend on your financing sources, such as savings, home equity or family loans
