How quickly can you file my income tax return?
Once I have all your documents, most straightforward returns are prepared within one to two working days. Complex returns with capital gains or business income take longer. You will see the computation before anything is submitted.
Which ITR plan do I need?
Salaried people with one house property and interest income usually need the Basic plan (ITR-1). If you have capital gains, more than one property or foreign assets, you need the Professional plan (ITR-2). Business and profession income needs the Business plan (ITR-3 or ITR-4). Message me your income sources and I will tell you which applies.
What documents do I need for ITR filing?
PAN, Aadhaar linked to PAN, a bank account number with IFSC, Form 16 if salaried, Form 26AS and the Annual Information Statement from the income tax portal, interest certificates and details of deductions such as 80C and 80D. Business filers also need profit and loss figures and GST details.
Do you ask for my bank OTP or UPI PIN?
Never. No genuine service needs your UPI PIN or a bank OTP. For e-verification of a return, the code goes to your own registered mobile number, and you are the one who completes it.
I was scammed online. What should I do first?
Call 1930 right away, then file a report at cybercrime.gov.in with screenshots, numbers and transaction IDs. Tell your bank immediately. The first hours matter most. Do not pay anyone who promises to recover your money for a fee.
