If you are very good at tax, you can give the company very good advice on tax avoidance or tax-related, make the company pay less taxes, and show your ability in tax audit and accounting, then your job is directly proportional to your salary.
Nowadays, many large companies will have special tax commissioners, so it is better to go to large companies to specialize in taxation.
If there are no big companies and only small companies where you are looking for a job, then finance is better, because you will also do tax work during the financial period, but all aspects are involved, so you are not very proficient in that kind.
Hand, I hope to give you good advice.
