After the status of interns in school changes, the legal relationship between interns and internship units may become a labor legal relationship. So this unit will decide your internship status until you get your diploma. If you or the school think that the internship time in this unit is too long, you should propose to shorten the period.
Internship allowance is also your personal income. Whether to pay taxes mainly depends on whether the allowance reaches the taxable amount of personal income (currently about 4,000 yuan per month). If the internship allowance given to you by this unit reaches the taxable amount, then this unit should be very good.
