It would be good if we are able to create a subtask to an existing task.
Thank you for your interest and feedback!
Reading the comments on this thread, they seem to follow two different asks. If you’re suggesting dependency between tasks (ie. task A must be completed before task B), please visit this thread: https://planner.uservoice.com/forums/330525/suggestions/13976094
If you’d like to suggest improvements to our existing checklist functionality, please share more with us in a comment below!

Sub tasks would allow me to organize my content. There is a major task that needs sub tasks. Making a new bucket results in too many buckets.. If I could click on a card and have it open other cards below it, that would be helpful. Making predecessors would also be great.

We've encountered situations where a user creates a task and checklist items. However, the task creater then realizes that the checklist items are more complex and wishes to "promote" checklist item as an independent sub-task (where the completion of the sub task does not rely on the completion of any other task) or as a dependent sub task (where the completion of the sub task is dependent on an earlier sub task). These sub-tasks would be have the same functionality as a base task (assignments, checklists, attachments, etc.), but the completion date could not be AFTER the base task. A per-plan configurable limit to nested tasks would allow plan creators to limit how granular tasks can get. Alternatively, a subscription admin could impose global limit for an organization.

Look at the functionality Asana brings for this. would be great if it could be replicated.
Would be graet to have sub-tasks and be able to assign sub-tasks to different people as well
Checklist items need @name like Trello and due dates...
Victor Forde commented
Agreed sub-tasks would be really useful. Then tasks can be grouped and an overall deadline. Then subtasks like what would be in a checklist for tasks be assigned to different individuals with a different (shorter) deadline to the overall group deadline. In the interim the checklist limit of 20 is an issue too. Why cap it?
yes this would be helpful. the way we currently use planner is for specific events. we have a bucket for unconfirmed events, when the event is confirmed it gets assigned and moved to a bucket of the type of event. Private Party, Fundraiser, Marketing. we use the checklists for the general task marking them with the date and user/s responsible (@user1, @user2). The problem is it doesn't really provide follow-up and notification. Responsible parties need to manage on their on their time and check in with the project. It works, but being able to assign people and assign a due date would be nice.
Where there are several persons working on a task, we would like to allocate checklist items (i.e.sub-tasks) to one person.
Ideally it would be good if tasks could be nested - so that dragging a task into another task - turns it into a sub-task or item on a check list within that task. Dragging a checklist item out of a task would turn it into its own full task.
Could there be 3 levels - tasks, sub-tasks,and sub-sub-tasks - all with tick boxes?
We specifically would like to be able to assign individual checklist items -- I want to have a task card that is either assigned to the person with overall responsibility for the task or no one, then each checklist item is assigned to an individual (ideally each checklist item would have its own due date as well). When individuals look in a roll-up view of their Planner items (e.g. the Teams Planner module "My Tasks" tab) they would see any task card where they have been assigned a checklist item.
The sub tasks need to be able to have different due dates, both from each other and from the overall task itself.
It would be great to be able to assign a sub task or an item from the checklist to another user on the team.

Check list is not a task.
A Task/Sub Task you can assign for some one to do as a dependency.
I'm working on a task related to Compter Backup.
 My Task would be storage.
-  Review Backup Policy (SLA)
-  Prepare documentation
Assign to Documentor
-  Getting vendor quote for storage
Assign to account manager
When you have finish the task, check list are more of sanity check or important point you want to remind you about.
The simple ability to indent tasks - thus creating sub tasks (A nice adder would be...if all indented tasks are complete, then the parent task is complete. Without promoting out as a separate item.)
Yes! Either this or have the ability to assign someone to a checklist item.
It would be great to be able to assign subtasks to different group members ... and with individual due dates and comments would be even better.
I agree with many comments below:
Subtasks (checklist items) need to be assigned to individuals.
I'd like to see an ability to have a Kanban board within a Kanban task. Basically an ability to create a parent board where I'd list existing Kanban boards as individual cards.

agreeing with several already ... this
Where each task can have a different owner and due date and comment tracking at the task level

Being a bit smart with URLs in checklist items will go a long was in my opinion:
If the Checklist item is a URL to anothe Planner Task:
1. deference it to show the Task Title instead of a long URL
2. make it clickable
subtasks (checklist items) assigned to individuals. Auto comment in the thread when that individual or others check off an item from the list.
It is crucial to a lot of projects that a historic timeline be kept for individual issues or tasks. If we could hold a time line feature from the comment section that shows all of the sub tasks or checklist items, it could be exported into a Microsoft project type chart showing when these were created and completed and by whom.
