1. Gather Your Important Tax Documents

Before you start filing your income tax return online, collect the documents that apply to your financial situation.

These might include:

- PAN and Aadhar details, if applicable.
- Salary Slips or Form 16.
- Statement of account and interest certificate.
- Form 26AS and annual information statement (AIS)
- Broker or mutual fund statements of capital gains.
- Investment, insurance and qualifying deduction records
- Home loan interest certificate (if any).
- Details of advance tax and Tax Deducted at Source (TDS)

Not all documents are needed for all taxpayers. Your requirements are based on your sources of income, deductions and the applicable ITR form.

2. Make a list of all income sources

One mistake is reporting salary and not other taxable income. Before filing ITR online, ensure that you check your financials for the financial year concerned.

Check if you received money from:

- Salary or pension.
- Fixed deposits and savings accounts
- Professional or freelance services;
- Commercial activities.
- Property rental.- mutual funds or other investments.
- Other supplies subject to tax.

Report income properly under the applicable tax law. Don’t think you can exclude income because tax was not deducted at source.

3. Verify AIS and Form 26AS

You can cross-check the financial information and tax credits reported against your PAN by referring to your Annual Information Statement and Form 26AS.

Compare available details with your bank statements, salary records and investment statements. If you see something that isn't right, dig into it. And comment on the portal where possible. Keep records of supporting information for your reason.

This review is an integral part of accurate ITR filing online.

4. Choose the Right ITR Form

Different income tax return forms are needed for different income situations. For example, a salaried person who is eligible and has simple income can use ITR-1 but capital gains, business income or other situations may require another form.

Select a form after reviewing the relevant eligibility criteria. Choosing the correct ITR form minimizes the chances of errors in your filing and the need for corrections later.

5. Compare the Available Tax Regimes Depending on your circumstances, you may have to compare the old and new tax regimes before filing.

Think about existing tax rates, typical deduction, qualified deductions and exemptions. Don't pick a regime just because a friend or colleague has chosen it. What choice is better for you depends on your income and benefits eligibility.

Check relevant rules and calculate your taxes on the official Income Tax Department website.

6. Double Check Your Return Before Mailing

Before you file your income tax return, make sure to do the following:

- Personal details are correct.
- All applicable income has been disclosed.
- TDS & other tax credits verified.
- Under the chosen regime, deductions are allowed.
- The bank account details are accurate.
- Any outstanding tax due has now been dealt with.
- The ITR form you have chosen is suited to your situation.
