How often do employers report 1099 earnings to government entities,
that is either the federal or state agencies, quarterly, annually, or
at their discretion?

Hi pennron,

Here you go - you should be able to find everything you need to know
on the following instructions sheet.

IRS: General Instructions for Forms 1099... 
B. When To File
"File Forms 1098, 1099, or W-2G on paper or magnetic media by March 1,
2004 (March 31, 2004, if filing electronically)... Brokers may file
Forms 1096 and 1099-B anytime after the reporting period they elect to
adopt (month, quarter, or year), but not later than the due date..."

"You will meet the requirement to file if the form is properly
addressed and mailed on or before the due date. If the regular due
date falls on a Saturday, Sunday, or legal holiday, file by the next
business day. A business day is any day that is not a Saturday,
Sunday, or legal holiday. See part H on page GEN-9 about providing
Forms 1098, 1099, 5498, and W-2G or statements to recipients."

So the short answer is, most businesses file once per year. I hope
this helps but if you have any questions, please post a clarification
request before closing/rating my answer.

Thank you,
