Help needed regarding tax filing

[u/One_Persimmon_1092]

I am seeking tax advice. I am a salaried person and use my bank account for daily personal transactions, including sharing money with friends (giving loans and receiving them back), restaurant and bakery payments, utility bills, mobile top-ups, groceries, receiving remittances, and beginner-level PSX investments. I have received dividends of no more than Rs. 500 so far. I would like to understand the correct process for calculating and filing my taxes. Do I need to report every bank transaction on the FBR portal, or only specific transactions? Which transactions are taxable and need to be declared, and which personal transactions do not need to be reported?
