I'm working in master branch. And what I tried to do is creating a tag for it. I made changes in the files. Afterwards I used this command line: 

```
git tag -a <tag_name> -m "tag information and commit message"

```

This seemed to work. I used:

```
git describe --tags

```

to show which tag is used and it showed the correct one

Then I used TortoiseGit to commit my changes, I pulled and pushed and the tag-checkmarks were checked. But when I had a look at the Bitbucket repo the commit was made to the master branch. The tag was not passed.

Is there a way to add the tag afterwards (to local and remote) to this commit? I couldn't find anything yet. What would be the usual procedure to commit changes under a tag?
