To expand on Trevor's answer, you can push a single tag or all of your tags at once.

Push a Single Tag

git push  

This is a summary of the relevant documentation that explains this (some command options omitted for brevity):

git push [[ […]]

...

The format of a parameter is…the source ref , followed by a colon :, followed by the destination ref …

The tells which ref on the remote side is updated with this push…If : is omitted, the same ref as will be updated…

tag means the same as refs/tags/:refs/tags/.

Push All of Your Tags at Once

git push --tags 
# Or
git push  --tags

Here is a summary of the relevant documentation (some command options omitted for brevity):

git push [--all | --mirror | --tags] [ […]]

--tags

All refs under refs/tags are pushed, in addition to refspecs explicitly listed on the command line.
