Yes. A report has a Tag property just like a form, so you can reference it in the report's VBA code with:

Me.Tag

For example, if you set the report's Tag property to a month number before opening it, the report can use that value to filter itself or set a label caption.

However, if you're using the same report as 12 subreports, I would normally use the Link Master Fields and Link Child Fields properties instead. Put the month number in the main report's record source, then link the subreport control to it. That way Access automatically filters each instance of the subreport to the appropriate month.

The important distinction is that the Tag belongs to the report object itself. If you have 12 copies of the same subreport open at once, they all share that same Tag value. So it isn't a good way to give each subreport instance a different month. Link Master/Child Fields is the cleaner solution for that situation.

This falls cleanly in the "try it yourself and see what happens" camp. Give it a shot. Let me know what happens. I haven't played with report tags in years. If you discover anything interesting, let me know. Could make a fascinating video.
