Starting a business can be very rewarding. It can also be a little overwhelming. From business plans to market strategies, and even tax responsibilities…there are many things to consider. Here’s what new business owners can do to help get off to a good start.

Choose a business structure. The form of business determines which income tax return a business taxpayer needs to file. The most common business structures are:
- Sole proprietorship: An unincorporated business owned by an individual. There’s no distinction between the taxpayer and their business.
- Partnership: An unincorporated business with ownership shared between two or more people.
- Corporation: Also known as a C corporation. It’s a separate entity owned by shareholders.
- S Corporation: A corporation that elects to pass corporate income, losses, deductions, and credits through to the shareholders.
- Limited Liability Company: A business structure allowed by state statute.
Choose a tax year. A tax year is an annual accounting period for keeping records and reporting income and expenses. A new business owner must choose either:
- Calendar year: 12 consecutive months beginning January 1 and ending December 31.
- Fiscal year: 12 consecutive months ending on the last day of any month except December.
Apply for an employer identification number. An EIN is also called a federal tax identification number. It’s used to identify a business. Most businesses need an EIN.
Have all employees complete these forms:
- Form I-9, Employment Eligibility Verification
- Form W-4, Employee’s Withholding Allowance Certificate
Pay business taxes. The form of business determines what taxes must be paid and how to pay them.

Taxpayers interested in starting a business can find information for some industries on the Industries/Professions Tax Centers webpage. Each state has additional requirements for starting and operating a business. Prospective business owners should visit their state’s website for info about state requirements.

Some S corporations may want to convert to C corporations

After last year’s tax reform legislation, some S corporations may choose to revoke their S election to be a C corporation because of the new, flat 21-percent C corporation tax rate. Before taking any action, S corporations should consult their tax advisors.

S Corporations and C Corporations are among the types of business structures. A C corporation is taxed on its earnings, and then the shareholder is taxed when earnings are distributed as dividends. S corporations elect to pass corporate income, losses, deductions and credits through to their shareholders for federal tax purposes. Shareholders of S corporations report the pass-through of income and losses on their personal tax returns and are assessed tax at their individual income tax rates. This allows S corporations to avoid double taxation on the corporate income. S corporations are responsible for tax on certain built-in gains and passive income at the entity level.

The Tax Cuts and Jobs Act includes two changes that affect a corporation’s revocation of an S election to be a C corporation:

The corporation should report net adjustments attributable to the revocation over six years. For more information see Revenue Procedure 2018-44.
Distributions of cash following the post-termination transition period may be treated as coming out of the corporation’s accumulated adjustments account and accumulated earnings and profits proportionally resulting in part of the distributions being non-dividend distributions from the C corporation. The non-dividend distributions may not be subject to tax at the shareholder level if the shareholder has sufficient stock basis. Additional guidance will be coming.

These law changes only apply to a C corporation that:

Was an S corporation on December 21, 2017,
Revokes its S corporation election after December 21, 2017, but before December 22, 2019, and
Has the same owners of stock in identical proportions on the date of revocation and on December 22, 2017.
