GENERAL INSTRUCTIONS - Filing Reports
For employers filing a paper-style report, quarterly contribution and wage reports are made using Form Ul-3/40. The original report must be filed, and the contribution payment made, no later than the last day of the month following the end of the quarter, April 30, July 31, October 31 and January 31. Reports and remittances personally delivered or postmarked after that date will be subject to penalty and/or interest. An employer who paid no wages during a quarter, but has not permanently ceased being an employer, must file a signed report showing "No Wages Paid This Quarter".
Non-profit organizations and local governmental entities which elected to make payments in lieu of contribution must file the contribution and wage report (Ul-3/40) quarterly even though contributions are not required.
