FAQ
Frequently Asked Questions
Typically: PAN & Aadhaar, Form 16 (for salaried), Form 26AS/AIS, bank statements, interest certificates, capital gains statements and investment proofs. We share a personalised checklist after the free consultation.
With Aadhaar authentication, GSTIN is usually allotted within 3–7 working days. We prepare the application, verify documents and follow up with the department until your certificate is issued.
A late fee under section 234F applies — ₹5,000 (₹1,000 if total income is below ₹5 lakh), plus interest on any tax due. A belated or revised return can still be filed until 31 December of the assessment year.
Private Limited Company is preferred by investors and offers limited liability and easier funding. LLPs suit professional firms, while proprietorship is the simplest for solo, low-compliance businesses. We help you compare before you commit.
After the free consultation, we share a fixed written quote based on your requirement. No hourly billing surprises, no hidden charges — the scope and price are agreed upfront.
