INCOME TAX
An individual whose annual income is more than the basic exemption limit of ₹2.5 lakh is required to file an ITR. The basic exemption limit for senior citizens (60 years onwards and less than 80 years) is ₹3 lakh, and for super senior citizens is ₹5 lakh.
A company, a partnership firm or a LLP ITR filing is mandatory even if:
- No income
- Loss incurred
- No business activity
ITR filing is compulsory irrespective of income if any of the following applies:
- Deposited ₹1 crore+ in current account
- Spent ₹2 lakh+ on foreign travel
- Electricity bill ₹1 lakh+
- TDS/TCS deducted in your PAN
- You hold foreign assets or foreign income.
Yes, if you want to carry forward losses for the succeeding tax years.
If you incurred loss in:
- Business / profession
- Share trading (intraday, F&O)
- Capital loss (shares, mutual funds, property)
👉 ITR must be filed within due date to carry forward losses to future years for set-off.
⚠️ If you don’t file ITR → loss lapses forever.
An assessee is required to file an Income Tax Return once their annual income exceeds ₹2.5 lakh. The fact that TDS has been deducted by the employer does not eliminate the need for filing the return. At the time of filing, details of total income, eligible deductions, and TDS credit must be correctly reported.

Yes, you need a separate GST registration (GSTIN) in the other state if you want to do business there, even temporarily.
Under Section 25 of the CGST Act, GST registration is state-wise. So:
GSTIN in State A ❌ cannot be used for supplying goods/services from State B.
You are treated as a Casual Taxable Person (CTP). Examples: Exhibition / trade fair, Temporary site work, Short-term consultancy / services, Seasonal business.
🔸 Registration is mandatory before starting business
🔸 Advance tax payment required (estimated liability)
Step 1 – Output GST
GST charged on sales. Example: Taxable sales ₹5,00,000 × 18% = ₹90,000
Step 2 – Input Tax Credit
GST paid on purchases. Example: Purchases ₹2,00,000 with GST ₹36,000 = Eligible ITC ₹36,000
Step 3 – Net Liability
Output GST – ITC = ₹90,000 – ₹36,000 = ₹54,000
Under Section 16 & Section 17(1) of the CGST Act: ITC is allowed only for goods or services used in the course or furtherance of business.
If the goods are for personal use, ITC is expressly blocked. Even if invoice is in firm’s name, GSTIN mentioned, payment from business account — ❌ ITC not admissible.

You can revive (restore) your cancelled GST registration if:

- Cancellation was due to non-filing of returns or non-compliance
- You are otherwise eligible to be registered under GST
📌 This process is called Revocation of Cancellation.
No expiry. GSTIN remains valid for a lifetime until you apply for cancellation or department cancels it due to non-compliance.
Yes — a registered person can apply for cancellation of GSTIN.
NO — a GSTIN itself cannot be transferred to another person or even to a family member.
GST registration is PAN-based. GSTIN is issued to a specific legal person. Another person (even spouse / son / brother) has a different PAN. Hence, GSTIN is non-transferable.
