Assuming that you are talking about 1099-MISC.  Note that there are other 1099s.check this post - Form 1099 MISC Rules & RegulationsQuick answer - A Form 1099 MISC must be filed for each person to whom payment is made of:$600 or more for services performed for a trade or business by people not treated as employees;Rent or prizes and awards that are not for service ($600 or more) and royalties ($10 or more);any fishing boat proceeds,gross proceeds of $600, or more paid to an attorney during the year, orWithheld any federal income tax under the backup withholding rules regardless of the amount of the payment, etc.

There are a few different ways of estimating the numbers and thinking about this question. Data from the most recent years are not available—at least not from a reliable source with rigorous methodology—but here is what I can tell you:The most popular type of 1099 is Form 1099-MISC—the form used to report non-employee income including those for self-employed independent contractors (as well as various other types of “miscellaneous” income)Since 2015, there have been just under 16 million self-employed workers (including incorporated and unincorporated contractor businesses). And the data from the BLS seems to suggest this number has been largely consistent from one year to the next: Table A-9. Selected employment indicatorsNow, the total number of 1099-MISC forms has been inching up each year—along with W-2 form filings—and may have surpassed 100 million filing forms. RE: Evaluating the Growth of the 1099 Workforce But this data only goes to 2014 because, again, it’s hard to find reliable data from recent tax years.In terms of the total number of Form 1099s, you’d have to include Interest and Dividend 1099 forms, real estate and rental income, health and education savings accounts, retirement accounts, etc. I’m sure the total number of all 1099 forms surely ranges in the hundreds of millions.Finally, not everybody who is supposed to get a 1099 form gets one. So if you’re asking about the total number of freelancers, the estimates range from about 7.6 million people who primarily rely on self-employed 1099 income and 53 million people who have some type of supplemental income.If you’re someone who’s responsible for filing Form 1099s to the IRS and payee/recipients, I recommend Advanced Micro Solutions for most small-to-medium accounting service needs. It’s basic but very intuitive and cheap.$79 1099 Software Filer & W2 Software for Small Businesses
