Heads‑up: This article is for general information only – not tax or legal advice. Always confirm specifics with a verified CA
GST vs. ITR - plain English difference.
- GST is a consumption tax on the supply of goods/services. You collect it (where applicable) from customers and deposit it to the government, filing periodic returns.
- ITR is your income tax return - it reports profits/income for the year and computes how much income tax you owe or get refunded.
Pick your business structure and tax regime (with a CA).
- Sole proprietor: Simplest to start; income is taxed in your personal return.
- Partnership/LLP: Separate legal entity; partners’ drawings vs. profits need clarity.
- Private Limited: More compliance; separates ownership and management; helpful for fundraising.
- Regimes and applicability: Discuss with your CA which GST and income tax regimes you qualify for and what’s optimal for your revenue model.
The compliance rhythm (example plan).
- Monthly/Quarterly GST returns (depending on your scheme and turnover category).
- Annual GST return (where applicable).
- Income tax advance/self assessment as scheduled; ITR filing annually
- TDS/TCS (if applicable) on salaries, contractor payments, etc.
- Audit requirements (if applicable) based on entity type/turnover — confirm with your CA.
Your 10 point startup compliance checklist.
- Business PAN, bank account, and key registrations in place.
- GST registration (if applicable) and portal access.
- Choose accounting method (cash vs. accrual) and set up bookkeeping.
- Configure invoicing with GST fields (where applicable) and sequential numbering.
- Maintain expense receipts (digital copies OK) with supplier GSTIN where relevant.
- Track input tax credit (ITC) and reconcile with vendor filings.
- Set calendar reminders for GST/ITR/TDS due dates.
- Review monthly P&L and cash flow; set aside tax floats.
- Back up data and keep records for statutory retention periods.
- Schedule a quarterly CA review to catch issues early.
Documents to keep tidy (founder pack).
- Incorporation documents, registrations, PAN, bank proofs.
- Invoices (sales), credit/debit notes; purchase bills.
- Expense vouchers, payroll records, TDS challans (if any).
- CA engagement letters, filings acknowledgments, and notices (if any).
Common mistakes (and how to avoid them).
- Missing deadlines → add reminders and delegate filings to a verified CA.
- Wrong invoicing → standardize templates; include GST fields where applicable.
- Ignoring ITC reconciliation → match vendor data routinely.
- Mixing personal & business expenses → separate accounts; document director loans/salary.

Frequently Asked Questions
Q1. Do I need GST from day one?
It depends on your activity and thresholds. A verified CA will confirm if and when you must register.
Q2. I have no revenue yet - do I still file?
Often yes. Many returns must be filed even with nil revenue to avoid penalties. Confirm with your CA.
Q3. Can I file GST and ITR myself?
You can, but mistakes are costly. Most founders save time and risk by using a verified CA.
Q4. What happens if I miss a return?
Late fees/interest may apply. File as soon as possible and consult a CA to regularize.
Q5. What records should I keep for an audit?
Sales/purchase invoices, bank statements, ledgers, payroll, and proof of filings. Keep digital backups and organize monthly.
