MERGING TAG
When merging an annotated (and possibly signed) tag, Git always
creates a merge commit even if a fast-forward merge is possible,
and the commit message template is prepared with the tag message.
Additionally, if the tag is signed, the signature check is
reported as a comment in the message template. See also
git-tag(1).
When you want to just integrate with the work leading to the
commit that happens to be tagged, e.g. synchronizing with an
upstream release point, you may not want to make an unnecessary
merge commit.
In such a case, you can "unwrap" the tag yourself before feeding
it to git merge, or pass --ff-only when you do not have any work
on your own. e.g.
git fetch origin
git merge v1.2.3^0
git merge --ff-only v1.2.3
