Which Forms Must I File?
This section provides information on which forms to file based on your business structure. It also gives you the due date for the returns.

Business Expenses:

Business expenses are the cost of carrying on a trade or business. These expenses are usually deductible if the business is operated to make a profit.

What can you deduct?

To be deductible, a business expense must be both ordinary and necessary.  An ordinary expense is one that is common and accepted in your industry or trade. A necessary expense is one that is helpful and appropriate for your trade or business. An expense does not have to be indispensable to be considered necessary.

It’s important to separate business expenses from the following expenses:

  • The expenses used to figure the cost of goods sold
  • Capital expenses
  • Personal expenses

Cost of Goods Sold

If your business manufactures products or purchases them for resale, you generally must value inventory at the beginning and end of each tax year to determine your cost of goods sold. Some of your expenses may be included in figuring the cost of goods sold. Cost of goods sold is deducted from your gross receipts to figure your gross profit for the year. If you include an expense in the cost of goods sold, you cannot deduct it again as a business expense.

The following are the type of expenses that go into figuring the cost of goods sold:

  • The cost of products or raw materials including freight
  • Storage
  • Direct labor costs (including contributions to pensions or annuity plans) for workers who produce the products
  • Factory overhead

Under the uniform capitalization rules, you must capitalize the direct costs and part of the indirect costs for certain production or resale activities. Indirect costs include rent, interest, taxes, storage, purchasing, processing, repackaging, handling, and administrative costs.

For Businesses with Employees

As a business owner, when another person performs work for you, you must first correctly classify that person as an independent contractor or employee.

If the person is an independent contractor, refer to Forms and Associated Taxes for Independent Contractors for your tax responsibilities.

If the person is classified as an employee you must have an Employer Identification Number (EIN). Your tax responsibilities include withholding, depositing, reporting, and paying employment taxes. You must also give certain forms to your employees, they must give certain forms to you, and you must send certain forms to the IRS and SSA.
