Masters in Tax, Worth It?

Hi Everyone, I work in public accounting and recently just finished the CPA exam and was thinking about getting my MST. I see many schools offer online programs and no GRE is required if you have the CPA. Currently I have a dual bachelors degree which gave me the 150 credits. My firm will cover 80% of the cost, but then I'm required to stay 2 more years once I finish. I believe I get a salary bump, but besides that do you guys think it's worth it?
