Awful site. We have been using this for the past 4 years and the site has gotten worse and worse each year. We are a professional accounting firm and file about 1000 1099s each year. The site is incredibly slow, and this year, two days before the filing deadline for 1099-Misc forms, the site stopped working and stopped allowing excel file imports. Tax1099.com's tech support was very unresponsive. Finally got through to someone who said they would help and they told us they would call us back by 7pm on 1/31/2018 with a solution and they never did. THey told us we would be able to email them our excel import files directly and that they would file them for us on time. But they never called back and never responded, leaving us up a creek without a paddle. Subsequent follow up calls were unsuccessful. STAY AWAY FROM THIS SITE if you need a reliable way to file your 1099 forms on time, before the deadline. Better to rely on a US based system that is designed for tax professionals, even if it costs more, as they will have the support staff needed when issues arise.
