Planner Limitations
SanthoshB1 These numbers are way out of date. Please ignore.
Would be nice if we got an update on this... been over a year since someone from Microsoft said they were working on it. Understood you're working on a lot but I would assume this is relatively low hanging fruit... If it can't be done soon it would be helpful to understand the complexities behind what's dragging this out...

After stumbling across this thread I put a ticket on O365 support portal which found its way to the Project Online & Planner support team who confirmed the following limitations (as of 31.07.18)
200 is a limit on the buckets in a Plan.
250 is the limit on active tasks in a Plan.
300 is the limit on tasks assigned to a user.
1500 Overall tasks that can be created in Planner Tenant.
