It's tax season, and if you've received an unfamiliar income form this year, it might be a 1099 tax form.

A 1099 form is used to document income received outside of a permanent salaried job. This includes money earned from gig work, interest, a real estate sale or a distribution from a tax-leveraged account, such as a health savings account. Any organization or individual you received a payment from is required to send this tax form to you by Jan. 31 each year; an employer is also required to distribute your W-2 form by this deadline.

It might be tempting to not report this money on your tax return, especially if the amounts are small, but if you don't, there's a good chance the IRS will know about it.

Businesses will also send a copy of your 1099 forms to the federal tax agency. Your tax return will be compared to what's on file to see if there are any discrepancies, and if the numbers vary, you put yourself at greater risk of being audited.

Here's what to know about the different types of 1099 tax forms, how to confirm you've received all your paperwork, and tips for an easier filing season.

How do I know what 1099s to look out for?

Any taxpayer can create a free ID.me account to see what forms they should expect to receive this year, since anyone issuing a W-2 or 1099 will also issue a copy to the IRS. Employees receive a W-2, whereas a 1099 form documents income you earned outside of W-2 earnings.

For some taxpayers, the majority (or even all) of their earnings in a given year will be 1099 income. Examples include someone who lives mostly off of Social Security income (SSA-1099), investment withdrawals (1099-B, 1099-DIV) or retirement account withdrawals (1099-R).

Other folks expect to receive both a W-2 and 1099s. An increasing number of people rely on side hustles and additional streams of income to make ends meet: 4 in 10 Americans have a side hustle, each making an average of $12,689 extra per year, according to a Harris poll commissioned by Zapier, a marketing automation company.

If you received one or more 1099s over the last few weeks, the first thing to do is create an account with the IRS and review the tax records associated with your Social Security number. Since the entity issuing your 1099 also has to issue it to the tax agency, you'll be able to make sure you haven't missed anything, according to Christina Taylor, Cash App Tax expert and head of eFile operations for Cash App. "I always recommend you pull your wage and income transcript [on ID.me] from the IRS first," Taylor said.
