All you need to know about ITR-1

Taxpayers should take care of the following while filing their income tax returns:

Carefully select the tax regime.
Download AIS and Form 26AS and check the actual TDS / TCS / tax paid. If you see any discrepancy, you should reconcile it with the Employer / Tax Deductor/ Bank.
Ensure details like PAN, permanent address, contact details, bank account details, etc., are correct in the pre-filled data.
Identify the correct return for you (from ITR-1 to ITR-7). Provide all the details in the return, such as total income, deductions (if any), interest (if any), taxes paid/collected (if any), etc. No documents are to be attached along with ITR-1.
e-File the return of income on or before the due date. The consequences of delay in filing returns include late filing fees, losses not getting carried forward, deductions and exemptions not being available.
After e-filing the return, always e-Verify it
