Quick summary

Finding the right tax consultant in Mumbai matters more than most people think. Here is a structured approach. From understanding your scope to onboarding and post-filing checks.

Step 1: Know what you need filed

Different tax situations need different levels of expertise. Be clear on your scope before approaching anyone:

  • Salaried with Form 16 only → straightforward ITR-1
  • Salaried with capital gains, stock options, or NRI income → ITR-2, needs CA
  • Business or professional income → ITR-3 or ITR-4, GST compliance also needed
  • Company filing → corporate tax, statutory audit, GST: full-service CA firm
  • GST only → monthly/quarterly GSTR-1 and GSTR-3B, find a GST practitioner
  • Both ITR and GST → bundled services from a single CA are more efficient

Step 2: Evaluate and compare

Three things to compare across at least 3 consultants:

  • Fee structure: fixed per return, or annual retainer covering all compliance?
  • Turnaround time: can they file before the deadline with time to review?
  • Communication: will they explain the return to you, or just file and send an invoice?
  • Software: do they file directly from their portal or yours?
  • Sector experience: manufacturing, IT, e-commerce, and professional services have different nuances

Step 3: Documents and onboarding

Prepare these before your first meeting to speed up filing:

  • Form 16 (if salaried). From your employer by 15 June
  • Bank statements for all accounts (savings and current)
  • Investment proof: LIC, PPF, ELSS, NPS, home loan statement
  • Capital gains: contract notes for shares/MF, property sale deed if applicable
  • GST returns filed (if applicable). Copies of GSTR-1, GSTR-3B
  • TDS certificates (Form 26AS / AIS from income tax portal)

Step 4: After filing. What to check

Your involvement does not end when the return is filed:

  • Verify the filed return on the income tax portal yourself. Do not rely solely on the CA
  • E-verify within 30 days (Aadhaar OTP is the fastest method)
  • Check Form 26AS after filing. Ensure all TDS credits appear
  • Check the Annual Information Statement (AIS) for any discrepancies
  • Keep all documents for 7 years. The assessment window is 3–4 years for most cases
