[IRS](https://www.irs.gov/businesses/small-businesses-self-employed/am-i-required-to-file-a-form-1099-or-other-information-return) ### Mandatory e-filing for information returns Businesses filing 10 or more information returns in a calendar year, including 1099s and W-2s, must file them electronically with the IRS. [IRS Information Return Reporting](https://www.irs.gov/businesses/small-businesses-self-employed/information-return-reporting) ### State sales tax economic nexus Since the Supreme Court ruling in South Dakota v. Wayfair in 2018, states can require businesses to collect sales tax once they cross a state-specific revenue or transaction threshold even without physical presence.
