Even if your self-employment income isn't very much, you still have to report it to the Internal Revenue Service.

In this tax tip: • New role, new tax chores   • Take heed of the title   • Don't trade ease for savings

Even if your self-employment income isn't very much, you still have to report it to the Internal Revenue Service.

But you may be able to file a much simpler form, especially since this year the IRS has expanded the guidelines for business filers.

New role, new tax chores
When you own an unincorporated small business by yourself, the IRS considers you a sole proprietor. This means you have some extra tax-filing work to do.

Your business earnings (or losses) are included as part of your individual income tax filing. To determine just how much to report on your 1040 (and you must use the long form), you itemize your operational income and expenses on either Schedule C or Schedule C-EZ.

As the name indicates, the C-EZ is a streamlined version of the more-detailed Schedule C. So when can -- and should -- you use one form over the other?

Take heed of the title
Guidance comes from the form names. Schedule C is titled Profit or Loss from Business. The EZ is Net Profit from Business. If you report a business loss, you can't use the short form.

The IRS also requires a Form C-EZ filer to operate only one business. If you run two or more sole proprietorships, you must file a Schedule C for each.

• Have business expenses of $5,000 or less (this is double the previous limit)
• Use the cash method of accounting
• Do not have inventory at any time during the year
• Never hire an employee
• Do not depreciate any business property
• Do not claim expenses for business use of your home
• Do not carry over passive activity losses from an earlier tax year.

Don't trade ease for savings
If you meet all of these requirements, then filing the simpler Schedule C-EZ probably will make your business tax life much easier.

But don't opt for simplicity just to cut down on your tax-filing duties. If your home office is indispensable to your firm's operation, claim the deduction and use Schedule C. What it costs you in time to complete the longer form could more than repay you in tax savings.

The IRS won't penalize you for taking every legitimate business deduction you can. Don't penalize yourself by using the wrong form.
