Tax Filing for the First Time: A 20-Something's Plain-English Guide

Filing income tax for the first time can feel confusing, but the basics are simpler than most young earners expect. This guide explains tax regimes, Form 16, ITR filing steps, common mistakes, and how to confidently manage taxes as a first-time salaried professional.

ITR Doesn't Have to Be Terrifying

Every year, millions of Indian first-time earners make one of two mistakes: they do not file their income tax return at all (believing, incorrectly, that it is optional if tax was deducted at source), or they delay filing until the deadline is imminent and rush through it without understanding what they are doing. Both mistakes have consequences.

Filing your ITR is not complicated if you understand the basic framework. Here is that framework.

Do You Need to File?

In India, filing an ITR is mandatory if your gross income exceeds the basic exemption limit — ₹2.5 lakh per year under the old tax regime, ₹3 lakh under the new tax regime (as of 2025; limits change, always verify). [Likely — these figures were current in mid-2025 but tax law changes annually]

Filing is also advisable even if your income is below the limit if tax has been deducted at source (TDS) and you want to claim a refund. If your employer deducted TDS from your salary, you can recover overpaid tax by filing — this is often the case for people who started employment mid-year.

The Two Tax Regimes

India currently has two income tax regimes:

Old tax regime: Higher tax rates but allows deductions (Section 80C investments, HRA, home loan interest, etc.) that reduce taxable income. Better for people who have significant investments and eligible deductions.

New tax regime: Lower tax rates, fewer deductions. Better for people who do not have major eligible investments or who prefer simplicity. From FY 2023-24, the new regime is the default — you must explicitly opt for the old regime if you prefer it.

For a fresh graduate with minimal deductions, the new regime often results in equal or lower tax. Run both calculations (the Income Tax Department's website has a calculator) before choosing. [Likely]

What You Need to File

Your Form 16, issued by your employer, contains all the information needed for salaried employees: total income, TDS deducted, and the breakdown of exempt allowances. This document does most of the ITR work for you.

Your bank interest income for the year (from savings accounts and FDs) must also be declared — your bank's annual statement or 26AS (a tax credit statement available on the income tax portal, incometax.gov.in) will show this.

Your AIS (Annual Information Statement), available on the income tax portal, shows all income and transactions that have been reported to the IT department under your PAN. Review it before filing to ensure it is accurate and that you are not missing anything.

Filing on the Income Tax Portal

Filing is done at incometax.gov.in. Login with your PAN. Select "File Income Tax Return." Select the relevant Assessment Year (note: AY 2025-26 covers income earned in FY 2024-25).

For salaried individuals with simple income (salary + bank interest, no business income), ITR-1 (Sahaj) is the appropriate form. For those with capital gains from mutual funds or stocks, ITR-2 is required.

The portal's pre-filled ITR feature automatically populates your income from Form 16 and 26AS data. Verify the pre-filled data, add anything missing (freelance income, rental income), review your tax calculation, and submit.

E-verify your return within 30 days of filing — through Aadhaar OTP, net banking, or by sending a signed physical copy to the CPC in Bengaluru. Verification completes the filing process.

Common First-Timer Mistakes

Not declaring bank interest. SB account interest above ₹10,000 is taxable (₹50,000 for senior citizens). FD interest is fully taxable. These are frequently omitted.

Filing after the deadline. The standard deadline for salaried individuals is July 31 of the assessment year. Late filing incurs penalties (₹1,000–5,000 depending on income level and delay duration) and loses certain benefits like the ability to carry forward losses.

Choosing the wrong ITR form. ITR-1 cannot be used if you have capital gains from selling stocks or mutual funds. Using the wrong form creates a defective return that requires refiling.

Not claiming legitimate deductions under the old regime. Investments in PPF, ELSS mutual funds, life insurance premiums, and employee PF contributions are deductible under Section 80C up to ₹1.5 lakh. Many first-time filers miss these.

Filing taxes is an annual obligation and an opportunity — to recover overpaid tax, to formally establish your income record, and to build the documented financial history that becomes relevant for loans and visa applications. Do it correctly, and it takes two to three hours per year.
