Individuals in the U.S. who have income as a sole proprietor or independent contractor (or any other term applied to a small business comprised of one person) are responsible for paying income taxes related to self-employment. Here are five independent-worker (self-employed, etc.) tax-related items the IRS recommends you be aware of. They link to more information found on the tax agency’s website. As always, we will remind you: Seek professional advice from trusted advisors when you are dealing with issues related to finances, taxes or the law.


First: Do you have income subject to the self-employment tax? The IRS has a self-guided “online interactive interview” that will help you determine whether or not you do.


1 | Estimated Tax

Self-employed taxpayers generally need to make quarterly estimated tax payments. IRS Publication 505, Tax Withholding and Estimated Tax, has details on making those payments.

2 | Schedule C or C-EZ

Self-employed taxpayers must file a “Schedule C, Profit or Loss from Business” or “Schedule C-EZ Net Profit from Business” with their Form 1040. For expenses less than $5,000, use Schedule C-EZ. Each form’s instructions provide the rules for which form to use.

3 | Self-Employment (SE) Tax

For those making a profit, self-employment and income tax may need to be paid. Self-employment tax includes Social Security and Medicare taxes. Use Schedule SE to figure the tax.

4 | Allowable Deductions

Taxpayers can deduct expenses paid to run a business. Expenses are described as either “ordinary” or “necessary.” An ordinary expense is one that is common and accepted in an industry. A necessary expense is one that is helpful and proper for a trade or business.

5 | When to Deduct

In most cases, taxpayers can deduct expenses in the year paid or the year incurred. Some costs must be ‘capitalized,’ however. This means deducting the cost over a number of years.

More advice from the IRS

All taxpayers should keep a copy of their tax return. Beginning in 2017, taxpayers using a software product for the first time may need their Adjusted Gross Income (AGI) amount from their prior-year tax return to verify their identity. Taxpayers can learn more about how to verify their identity and electronically sign tax returns at Validating Your Electronically Filed Tax Return.
