Step-by-Step Guide: How to File Taxes Correctly
1. Gather All Financial Documents
Before filing, collect all relevant documents, such as:
- Salary slips or income statements
- Bank statements and interest income
- Investment proofs (mutual funds, stocks, bonds)
- Home loan or mortgage statements
- Medical insurance or education expense receipts
- Business income and expense records (for self-employed)
Having all documents ready ensures accurate reporting.
2. Determine Your Taxable Income
Calculate your total income from all sources, including:
- Salary and bonuses
- Freelance or self-employment income
- Rental income
- Investment income (dividends, interest, capital gains)
Subtract eligible deductions and exemptions to determine your taxable income.
3. Choose the Correct Tax Filing Method
Depending on your country and type of income, choose the appropriate filing method:
- Online Filing: Many tax authorities provide e-filing portals for convenience.
- Paper Filing: Some taxpayers prefer submitting physical forms.
- Professional Filing: For complex situations, hire a tax consultant or accountant.
4. Apply Deductions and Exemptions

Claim all eligible deductions to reduce taxable income, such as:
- Retirement contributions
- Health insurance premiums
- Education expenses
- Home loan interest and principal repayment
- Charitable donations
Make sure all claims are supported with proper documentation.
5. Calculate Taxes and Pay Dues
Use tax slabs or applicable rates to calculate tax liability. If necessary, pay advance tax, self-assessment tax, or other required payments before the deadlines to avoid penalties.
6. Double-Check Before Submission
Verify all entries, income figures, deductions, and personal details. Mistakes like incorrect account numbers, mismatched PAN/TIN, or missing information can lead to processing delays or penalties.
7. File the Tax Return
Submit your tax return using the chosen method. If filing online, save confirmation receipts and acknowledgment numbers. Keep a copy of the filed return for future reference.
8. Keep Records Safely
Maintain organized records of all filed returns, receipts, and proofs of deductions for at least 5–7 years (depending on local law). This helps in case of audits or disputes.
