Peak Filing is the busiest time of the year for filing Annual Returns.
Peak Filing day is 25 November, the deadline for companies with an Annual Return date of 30 September, and during the month of November, approximately 52,000 Annual Returns are due to be filed.
Due to increased demand, Peak Filing may mean:
-Longer waiting room/waiting time to access CORE
-The potential for slower system speed due to increased service demand
-Increased likelihood of technical issues
We recommend you file now, don’t leave filing to the last minute.
