Instagram allows 3o#s and Geotag.
Hashtags are used for searchable on social media but unlike Twitter, Instagram wants you to use thirty of them. Adding a Geotag to your post can in improve your searchable and engagements on your Instagram posts. No putting any tags will hinder you in getting more followers and likes from who do not follow you. So remember to keep your hashtags relevant to your post, and remember that no amount of hashtags can save a low qualityInstagram post.
