Polite
Casual

おめでとう is casual, for friends, family and people younger than you. おめでとうございます is polite, for teachers, managers, customers and anyone you speak to with です and ます. Put the occasion first: お誕生日おめでとうございます (otanjōbi omedetō gozaimasu), happy birthday. The New Year greeting uses it too: あけましておめでとうございます (akemashite omedetō gozaimasu).

Correct
What people say wrong
Congrats. Warm with friends, too casual for a teacher or a boss.
The mistake to avoid. Learners often learn おめでとう first and use it with everyone. To a teacher or a manager, it sounds too familiar. Add ございます. Some learners also try おめでとうです. You may hear it in casual speech, but おめでとうございます is the standard polite form.
