How to File ITR with Multiple Income Sources — Salary, Rent, Capital Gains, and Interest Combined (AY 2026-27)

Most tax guides focus on one type of income — salary, rental income, or capital gains — in isolation. But in reality, many Indian taxpayers earn from multiple sources simultaneously. You might have a full-time job, a flat you rent out, some mutual fund redemptions, and FD interest. When filing season arrives, you need to combine all of these into one ITR, compute your total taxable income, and choose the right form.

This guide walks you through exactly that — with a realistic example and step-by-step calculations for AY 2026-27.

The Five Heads of Income Under Indian Tax Law

The Income Tax Act groups all income into five heads:

1. Income from Salary — salary, allowances, perquisites, pension
2. Income from House Property — rental income (or deemed rental income from a second property)
3. Profits and Gains from Business or Profession — business income, freelance income, professional fees
4. Capital Gains — gains from selling stocks, mutual funds, property, gold, or other capital assets
5. Income from Other Sources — FD interest, savings account interest, dividends, family pension, gifts, lottery winnings

Your total income is the sum of income computed under each applicable head, after deductions and exemptions specific to each head.

Which ITR Form Should You Use?

The moment you have income beyond salary and one house property, your ITR form choice changes:

Key rule: If you have any capital gains at all — even Rs 500 from a mutual fund redemption — you cannot file ITR-1. You must file ITR-2.

If you also have business or freelance income alongside salary and capital gains, you need ITR-3 (or ITR-4 if you use presumptive taxation).

A Realistic Example: Computing Total Income Across All Heads

Let us work through a complete example. Meet Priya — she is 34, works in Bengaluru, and has income from four sources in FY 2025-26.

Head 1: Income from Salary

Priya earns a CTC of Rs 18 lakh. Her Form 16 shows:

Under the new tax regime, she gets a standard deduction of Rs 75,000.

Taxable salary under new regime: Rs 16,50,000 − Rs 75,000 = Rs 15,75,000

Under the old tax regime, she can also claim HRA exemption. She pays rent of Rs 25,000 per month in Bengaluru (metro city).

HRA exemption is the minimum of:

• HRA received: Rs 4,50,000
• 50% of basic (metro): Rs 4,50,000
• Rent paid minus 10% of basic: Rs 3,00,000 − Rs 90,000 = Rs 2,10,000

HRA exemption = Rs 2,10,000

Taxable salary under old regime: Rs 16,50,000 − Rs 50,000 (standard deduction) − Rs 2,10,000 (HRA) = Rs 13,90,000

Head 2: Income from House Property

Priya owns a 2BHK flat in Pune that she rents out for Rs 20,000 per month. She has a home loan on this property with annual interest of Rs 2,40,000. She paid Rs 15,000 in municipal taxes during the year.

Priya has a loss of Rs 82,500 from house property. This is important — she can set off this loss against her salary income, up to Rs 2,00,000 per year.

Note: Under the new tax regime, interest deduction under Section 24(b) is available only for let-out property (not self-occupied). Since Priya's property is rented out, she can claim it under both regimes. The 30% standard deduction on NAV is also available under both regimes.

Head 3: Capital Gains

During FY 2025-26, Priya made two transactions:

Equity mutual fund redemption (held for 14 months):

• Purchase value: Rs 3,00,000
• Sale value: Rs 3,65,000
• Long-term capital gain: Rs 65,000

LTCG on equity mutual funds above Rs 1.25 lakh is taxed at 12.5%. Priya's LTCG of Rs 65,000 is below the Rs 1.25 lakh exemption threshold, so LTCG tax = Rs 0.

Debt mutual fund redemption (held for 2 years):

• Purchase value: Rs 2,00,000
• Sale value: Rs 2,30,000
• Capital gain: Rs 30,000

For debt mutual funds purchased after April 1, 2023, gains are always treated as short-term capital gains regardless of holding period, and taxed at your slab rate.

Total capital gains to report: Rs 65,000 (equity LTCG, exempt) + Rs 30,000 (debt fund STCG, taxable at slab rate).

Head 4: Income from Other Sources

Priya also has:

Under the old regime, savings account interest up to Rs 10,000 is exempt under Section 80TTA. Under the new regime, this deduction is not available.

Putting It All Together: Total Income Computation

Under the New Tax Regime

Note: Under the new regime, the house property loss set-off against other income is allowed (up to Rs 2,00,000), and Section 24(b) interest deduction is available for let-out property.

Tax calculation under new regime (AY 2026-27 slabs):

Plus, LTCG tax on equity = Rs 0 (below threshold). Debt fund gains are taxed at slab rate (already included above).

Under the Old Tax Regime

Tax calculation under old regime:

The Verdict for Priya

The new tax regime saves Priya Rs 67,860. Even with HRA exemption and Section 80C/80D deductions under the old regime, the new regime wins because her total deductions (around Rs 3.95 lakh including HRA) are not enough to offset the lower slab rates of the new regime.

This is common for taxpayers in the Rs 15–20 lakh range — the old regime typically wins only when total deductions exceed Rs 4.5–5 lakh. See our regime comparison by salary brackets for more scenarios.

How Set-Off of Losses Works Across Heads

When you have a loss under one head of income, you can set it off against income under another head — but there are important rules:

House property loss can be set off against income under any other head, up to Rs 2,00,000 per year. Any excess loss is carried forward for up to 8 years and set off against future house property income only.

Capital losses can only be set off against capital gains — never against salary, rental income, or interest. Long-term capital losses can only be set off against long-term capital gains. Short-term capital losses can be set off against both short-term and long-term gains.

Business losses cannot be set off against salary income (except in specific cases for certain professions).

In Priya's case, her house property loss of Rs 82,500 is fully set off against salary income since it is below the Rs 2,00,000 limit.

Common Mistakes When Filing with Multiple Income Sources

1. Forgetting to report small capital gains. Even if you redeemed Rs 10,000 worth of mutual funds, the capital gain must be reported. The Income Tax Department receives this data from registrars, and mismatches trigger notices. Check your AIS (Annual Information Statement) before filing.

2. Using ITR-1 when you have capital gains. ITR-1 does not have schedules for capital gains. If you file ITR-1 with unreported capital gains, you may receive a notice under Section 143(1).

3. Not claiming house property loss set-off. Many taxpayers report rental income separately but forget to set off the loss (if interest exceeds rental income) against salary. This is a legitimate deduction that reduces your tax.

4. Double-counting TDS. When you have TDS deducted on FD interest (by the bank), TDS on salary (by your employer), and TDS on rent (by your tenant), ensure you claim all TDS credits in the correct schedules. Cross-check against Form 26AS.

5. Mixing up holding periods. The tax rate on capital gains depends entirely on the asset type and holding period. Equity and equity mutual funds use a 12-month threshold for long-term. Debt funds purchased after April 2023 are always short-term. Property and gold use a 24-month threshold. Getting this wrong means paying the wrong tax rate.

6. Ignoring advance tax obligations. If your total tax liability (after TDS) exceeds Rs 10,000 in a financial year, you are required to pay advance tax. This is common when you have significant rental income, capital gains, or FD interest where TDS does not cover the full liability. Missing advance tax leads to interest under Section 234B and 234C.

Step-by-Step: How to File ITR-2 with Multiple Income Sources

1. Gather all documents: Form 16, rent receipts (if claiming HRA), home loan interest certificate, broker capital gains statement, bank interest certificates, and Form 26AS/AIS.

2. Download AIS from the income tax portal. Cross-verify every transaction — FD interest, mutual fund sales, dividends, and rent received. If anything is missing or incorrect, submit feedback on the AIS portal.

3. Compute income under each head on paper first (as we did above for Priya). This avoids errors during online filing.

4. Choose your tax regime before starting the ITR. You can compare both using the computation approach shown above. Once you start filling ITR-2 on the portal, you will select the regime upfront.

5. Fill Schedule Salary using Form 16 details. Enter gross salary, exemptions (HRA, LTA under old regime), and standard deduction.

6. Fill Schedule HP for house property. Enter the tenant's name, PAN, rent received, municipal taxes, and home loan interest. If you have a loss, the portal will automatically set it off.

7. Fill Schedule CG for capital gains. For stocks and equity mutual funds, use the capital gains statement from your broker. For debt funds, calculate gains manually if your AMC does not provide a statement.

8. Fill Schedule OS for other sources — FD interest, savings interest, dividends.

9. Fill Schedule TDS — enter TDS details from Form 26AS. The portal pre-fills some of this, but always verify.

10. Verify tax computation. Before submitting, review the computation summary. Check that losses are set off correctly and TDS credits match.

11. Pay any remaining tax via challan before submitting. If you owe self-assessment tax, pay it through the e-Pay Tax portal.

12. Submit and e-verify your return within 30 days.

Key Takeaway

Filing ITR with multiple income sources is not as complicated as it seems — it is methodical. Compute each head independently, set off applicable losses, add everything up, and choose the regime that gives lower tax. The critical step is verification: match every transaction in your ITR against your AIS before submitting. A mismatch you catch before filing costs nothing; a mismatch the department catches later costs you time, interest, and potentially a penalty.
