Help--Best plan from here? (Accounting)

<p>I am a senior graduating next semester with a Psychology major and Biology and Accounting minor. I originally decided to Minor in Accounting because I wanted some sort of business background, but I really enjoy it (I had already finished my psychology at this point, so I had free space in my schedule). Because of this, I am taking more accounting classes required than the minor, and would have taken every accounting class that a major has taken by the time I graduate in May (Every single accounting course offered at my university). However, the reason why I haven't obtained the major is because I haven't taken all of the business prerequisites (such as statistics, managerial finance, decision science, etc)---this would take me an extra YEAR.<br>
I want to pursue a career in accounting and get my CPA, and have considered the following options:
1) Stay the extra year and get my bachelors in accounting (pro: wouldn't have to take any more accounting classes, my scholarship would transfer for a 5th year)
2) Graduate in May and pursue a masters in accounting (I've read a lot about a masters in accounting not making you much more competitive than a bachelors, I would have to repeat courses, and it would be more expensive for me than a bachelors..is it worth it?)
3) Graduate in May and pursue a MS in taxation. I have taken two courses in tax and want to specialize in this area as a CPA. As with the accounting masters, this would be more expensive for me than the bachelors but my research tells me that a MS in taxation leads to a pay increase. However, my main concern is that my bachelors in psychology and ms in taxation will not make me that competitive as an accountant, or in the process for applying to the Big 4. Unfortunately a minor and the fact that I took every accounting class offered at my university won't easily show up on my transcript, although I'm sure I can integrate that in my resume/interview.</p>

<p>I am thinking that the 3rd option seems to be the best thing to do with my fifth year/after undergrad plans. If you are in the accounting/tax field, please give me your input. Thank you!</p>
