filing an income tax return is not complicated. it follows a step-by-step process.
the key is preparation. the actual filing takes minutes once the documents are ready.
who must file
itr filing is mandatory if total income exceeds the basic exemption limit. under the new tax regime, the basic exemption limit is ₹4 lakh. under the old regime, it is ₹2.5 lakh.
filing is also mandatory if any of these apply:
- expenditure on foreign travel exceeds ₹2 lakh
- electricity consumption exceeds ₹1 lakh
- deposits above ₹1 crore in current accounts
- business receipts exceed ₹60 lakh
- professional receipts exceed ₹10 lakh
- tds and tcs amounts exceed ₹25,000
- holding foreign assets or signing authority over foreign accounts
documents required
gather these before starting:
- pan and aadhaar (must be linked)
- form 16 from employer (tds certificate)
- bank statements for all accounts
- annual information statement (ais) and form 26as
- capital gains statements from broker or mutual fund platform
- investment proofs (section 80c, 80d, etc.)
- home loan interest certificate (if applicable)
- rent receipts (if claiming hra)
- interest certificates from banks
the most important document is the annual information statement (ais). it is the tax department’s record of financial transactions. if any income appears in ais but not in the itr, the system will flag it.
filing an itr online takes a few steps. go to www.incometax.gov.in. pick the right form. itr-1 works for salary and interest income. itr-2 is for capital gains. choose the tax regime. check the pre-filled data. submit and e-verify within 30 days. the deadline for most people is july 31.
step-by-step filing process
step 1: register on the e-filing portal.
go to www.incometax.gov.in. click on register. sign up using pan, aadhaar, mobile number, and email.
step 2: log in and start filing.
login with pan and password. go to e-file > income tax returns > file income tax return. select assessment year 2026-27. choose “online” as the filing mode.
step 3: select the correct itr form.
choosing the wrong form is a common mistake. it leads to defective return notices.
itr-1 (sahaj). for resident individuals with total income up to ₹50 lakh. income from salary, pension, one house property, and other sources like bank interest. no capital gains. no foreign income or assets.
itr-2. for individuals with capital gains, foreign assets, multiple house properties, or income from more than one source. no business income.
itr-3. for those with business or professional income. freelancers and consultants also use this form.
itr-4 (sugam). for taxpayers opting for presumptive taxation under sections 44ad, 44ada, or 44ae. total income must be up to ₹50 lakh.
step 4: choose the tax regime.
the new tax regime is the default. if old regime is preferred, it must be selected while filing.
new regime rates (fy 2025-26):
- up to ₹4 lakh: 0%
- ₹4-8 lakh: 5%
- ₹8-12 lakh: 10%
- ₹12-16 lakh: 15%
- ₹16-20 lakh: 20%
- ₹20-24 lakh: 25%
- above ₹24 lakh: 30%
standard deduction: ₹75,000. rebate under section 87a makes income up to ₹12 lakh tax-free. effective zero-tax limit for salaried employees: ₹12.75 lakh.
old regime may be beneficial if deductions exceed ₹3.5-4 lakh. these include section 80c (up to ₹1.5 lakh), hra exemption, home loan interest (up to ₹2 lakh), and section 80d (health insurance).
step 5: verify pre-filled data.
the portal pre-fills data from ais and form 26as. verify it carefully. if any income source appears in ais but is not reported in the itr, notices are triggered.
step 6: enter deductions.
under the old regime, claim deductions under sections 80c, 80d, 80e, and others. ensure all claims have proper documentation.
step 7: preview and submit.
review all details. check for mismatches. preview the return. if tax is due, pay through the portal.
step 8: e-verify the return.
e-verification must be completed within 30 days of filing. without it, the return is invalid.
methods to e-verify:
- aadhaar otp
- electronic verification code (evc) through net banking
- evc through bank account or demat account
- digital signature certificate
if the return is not e-verified within 30 days, the filing date shifts to the verification date. penalties for late filing may apply.

not reporting all income. bank interest, fixed deposit interest, and dividend income must be reported. the ais has this data already.
claiming deductions without documentation. all claims should be verifiable.
missing the deadline. late filing incurs penalties. losses cannot be carried forward if the return is filed late.
not e-verifying the return. the return is invalid without verification.
