Annual Return (Companies Act):
- File within 28 days of holding AGM
- AGM must be within 6 months of year-end
- June 30 year-end → AGM by Dec 31 → Annual Return by Jan 28
Step 4: Track Everything From Day 1
Record Keeping Essentials
What to keep (minimum 7 years):
Income Records:
- All invoices issued to customers
- Receipt books
- Bank deposit records
- Cash register tapes
- Payment confirmations (bank transfers, check stubs)
Expense Records:
- All receipts for business purchases
- Invoices from suppliers
- Bank statements
- Credit card statements (business expenses)
- Petty cash records
- Vehicle logbook (if claiming vehicle expenses)
Tax Records:
- Tax returns filed
- Payment receipts
- Assessment notices
- Correspondence with MRA
How to organize:
Physical receipts:
- Accordion folder with monthly dividers
- Photograph/scan receipts immediately (fade protection)
- Store in dry, safe place
Digital records:
- Accounting software (auto-categorized)
- Cloud storage (Google Drive, Dropbox)
- Folder structure: Year → Month → Category
- Regular backups
Best practice:
- Enter expenses daily or weekly (not monthly)
- Reconcile bank account monthly
- Review profit & loss monthly
- Keep business and personal completely separate
Separate Business and Personal
Critical for tax compliance:
1. Bank Account
- Open dedicated business bank account
- Use only for business transactions
- Never mix personal expenses
- Makes tax filing 10x easier
2. Credit Card
- Apply for business credit card
- Use only for business expenses
- Clear documentation
3. Accounting
- Never record personal expenses in business books
- If you use business money personally, record as "owner's draw" (self-employed) or "director's loan" (company)
Why it matters:
- Clean tax reporting
- Easy expense tracking
- MRA audit protection
- Clear business picture
Step 5: Plan for Tax Payments
Estimate Your Tax Liability
Self-Employed Example:
Conservative scenario:
- Expected annual income: Rs 600,000
- Expected expenses: Rs 200,000
- Expected profit: Rs 400,000
- Tax calculation: (Rs 400,000 - Rs 390,000) × 10% = Rs 1,000
- Estimated tax: Rs 1,000
Set aside: Rs 100/month or 1% of revenue (conservative)
Optimistic scenario:
- Expected annual income: Rs 1,200,000
- Expected expenses: Rs 300,000
- Expected profit: Rs 900,000
- Tax calculation: Rs 36,000 + (Rs 900,000 - Rs 750,000) × 15% = Rs 58,500
- Estimated tax: Rs 58,500
Set aside: Rs 5,000/month or 10% of revenue
Company Example:
Expected profit: Rs 800,000
- Corporate tax: Rs 800,000 × 15% = Rs 120,000
- Estimated tax: Rs 120,000
Set aside: Rs 10,000/month or 15% of revenue
Create Tax Savings Plan
Strategy 1: Separate Savings Account
- Open separate savings account for tax
- Transfer estimated tax amount monthly
- Don't touch this money (pretend it's not yours)
- Use funds to pay tax when due
Example:
- Set aside: Rs 5,000/month
- After 12 months: Rs 60,000 saved
- Pay tax from this pool
Strategy 2: Quarterly Deposits
- Calculate tax quarterly
- Set aside at end of each quarter
- Adjust if income varies
Strategy 3: Percentage of Revenue
- Self-employed: Set aside 10-15% of every payment received
- Company: Set aside 15-20% of revenue
- Automatic transfer when payment received
Step 6: Maximize Deductions (Legally)
Common First-Year Deductions
Startup Costs (Often forgotten):
- Business registration fees
- Legal and professional fees for incorporation
- Initial marketing materials (business cards, website)
- Equipment purchased before starting operations
- Market research expenses
Ongoing Deductible Expenses:
- Office rent
- Home office portion (if working from home)
- Internet and phone (business portion)
- Computers, laptops, software
- Professional fees (accounting, legal)
- Marketing and advertising
- Insurance (professional indemnity, public liability)
- Bank fees
- Training courses related to business
- Professional memberships
Vehicle Expenses (if used for business):
- Track all business kilometers
- Claim proportionate share of:
- Fuel
- Maintenance
- Insurance
- Depreciation
Example:
- Total vehicle costs: Rs 100,000/year
- Business use: 40% (from logbook)
- Deductible: Rs 40,000
What You CANNOT Deduct
❌ Personal living expenses
❌ Personal clothing (unless uniform)
❌ Entertainment (lunches, dinners unless directly revenue-generating)
❌ Fines and penalties
❌ Personal travel
❌ Personal portion of mixed-use expenses
Smart Tax Planning in Year 1
December strategies (if calendar year):
To reduce tax:
- Accelerate expenses into December (pay early)
- Delay invoicing until January (if using cash basis)

- Write off bad debts
- Make charitable donations to approved organizations
To increase income (if staying below threshold):
- Invoice and collect before Dec 31
- Recognize all earned income
- Delay expenses to January
Example:
- Current profit: Rs 385,000
- Strategy: Stay below Rs 390,000 threshold (0% tax)

Step 8: Common First-Year Mistakes to Avoid
1. Not Registering for TAN
Mistake: Starting business without registering for tax
Consequence: Cannot file returns, penalties for late registration
Solution: Register for TAN in first month of operation
2. Mixing Business and Personal
Mistake: Using personal account for business or paying personal expenses from business
Consequence: Messy records, missed deductions, audit risk
Solution: Separate bank account and credit card from day 1
3. Not Tracking Expenses
Mistake: Throwing away receipts or not recording expenses
Consequence: Pay more tax (can't prove deductions)
Solution:
- Receipt for every expense (photo immediately)
- Enter in accounting software weekly
- Keep organized records
4. Forgetting About Tax
Mistake: Spending all revenue without setting aside for tax
Consequence: Can't pay tax when due, penalties and interest
Solution: Set aside 10-15% of revenue monthly in separate account
5. Filing Late
Mistake: Missing March 31 (individuals) or September 30 (companies) deadline
Consequence:
- Rs 1,000 penalty + Rs 200/week thereafter
- Interest on unpaid tax (0.5% per month)
- Stress and audit risk
Solution:
- Calendar reminder for 2 weeks before deadline
- Prepare early (February for individuals, August for companies)
- File by March 15 or September 15 (buffer for issues)
6. Not Keeping Records Long Enough
Mistake: Throwing away records after filing
Consequence: Cannot defend against MRA audit
Solution: Keep all records for minimum 7 years
7. Claiming Non-Business Expenses
Mistake: Deducting personal meals, entertainment, personal vehicle use
Consequence: MRA audit, disallowance, penalties for tax evasion
Solution: Only claim legitimate, provable business expenses
8. Not Getting Professional Help
Mistake: Trying to handle complex tax situation alone
Consequence: Errors, missed opportunities, overpaying tax
Solution: Hire accountant if:
- Income > Rs 500,000

- Employees
- Don't have time/knowledge
