I would like for Notepad++ to add the closing tag when I finish typing the open tag. I know there is a plugin to do this for XML but it doesn't work on my HTML files and I have yet to find one that does.

I couldn't find anything for a tag closure, but if you turn on the auto-completion does that do what you need it to?
Autocomplete feature is disabled by default,
but a simple Preferences setup will get you using the new auto-complete feature in no time at all. Go to Settings -> Preferences, and switch to the Backup/Auto-competion tab. At the bottom of that screen you’ll see where you can enable auto-completion, and you can optionally turn on the “show function parameters” feature as well. It works for CSS, PHP, Javascript, and html also.

Try going into TextFX / TextFX Settings and check 'auto close XHTML tags'. This makes it work in plain HTML files too. You may need to install it if using a newer version of Notepad++
