NRI Tax Compliance: Navigating ITR Filing Challenges in 2026

Every year, thousands of NRIs sit down in front of a screen somewhere in the world, open their Indian bank statements, and think: “Where do I even begin?” The ITR filing process for non-residents has never been simple, but 2026 has added a few more layers to it. New disclosure requirements, updated DTAA interpretations, and increased scrutiny from the tax department mean that getting it wrong this year carries real consequences.
This isn’t meant to scare you. If you plan well and work with the right team, it’s manageable. But if you’ve been putting it off or assuming “my income is outside India, so I don’t have to worry,” you might want to read this carefully.

What Determines Your Residential Status in 2026

Before anything else, your tax liability in India depends entirely on whether you are a Resident, NRI, or RNOR (Resident but Not Ordinarily Resident). The Income Tax Act uses a day-count rule for this.

If you were in India for less than 182 days during FY 2025-26, you are generally an NRI. But it gets complicated. The 2020 amendment introduced a 120-day rule for certain high-income individuals, and that still applies. If your total Indian income exceeds Rs 15 lakh and you were in India for 120 or more days during the year, you may be treated as a resident for tax purposes.

This is where many NRIs get the first wrong assumption. They count calendar days loosely, miss the threshold, and end up filing under the wrong status. A wrong residential status declaration can trigger reassessment proceedings down the line.

Get the day count right first. Everything else flows from there.

1. Income That NRIs Must Declare in India

As an NRI, you are taxed only on income earned or received in India. This includes:

• Rental income from Indian property
• Interest from NRE/NRO accounts (NRE interest is exempt; NRO interest is taxable)
• Capital gains from selling Indian property, shares, or mutual funds
• Business income from operations in India
• Salary received in India for services rendered here

Your salary earned abroad, your overseas bank interest, your foreign investments — none of that is taxable in India. But the moment money flows into your Indian accounts from those sources and generates returns here, you need to track it.

NRO accounts are a common trap. Many NRIs park money there without realising that the interest accruing on it is fully taxable in India at applicable slab rates, with no basic exemption limit available for NRI taxpayers in several cases.

2. The DTAA Confusion That Trips Most NRIs

India has Double Taxation Avoidance Agreements (DTAAs) with over 90 countries. The purpose is to ensure you don’t pay tax on the same income twice. But understanding how to apply DTAA benefits correctly is genuinely complicated, and most people either don’t claim them at all or claim them incorrectly.

To avail DTAA benefits, you need a Tax Residency Certificate (TRC) from the country where you are a resident. This has to be submitted in the right format. Without it, the Indian tax authority can refuse the treaty benefit and tax you at full domestic rates.

For NRIs in the US, UK, UAE, Canada, or Singapore, the treaty provisions vary significantly. UAE is a particularly interesting case because there’s no income tax there, but the India-UAE DTAA still has specific provisions around capital gains and business income that many NRIs overlook.

If you haven’t claimed DTAA benefits you were entitled to in previous years, it may still be possible to rectify that. But it requires proper documentation and professional guidance, not a self-filed correction.

3. Foreign Asset Disclosures Have No Mercy

Schedule FA in the ITR form requires NRIs who qualify as residents in any year to disclose foreign bank accounts, investments, and assets. This is not optional. Non-disclosure is treated as a violation under the Black Money Act, and penalties can run up to 3x the value of undisclosed assets.

Even if you became a resident in India briefly during the year due to travel, that one financial year can trigger disclosure obligations. And this is exactly the kind of thing that slips through the cracks when you’re managing your tax filing yourself from abroad.

The good news: if you stayed NRI throughout the year, Schedule FA doesn’t apply to you. But verify your residential status carefully before assuming this.

4. Capital Gains From Indian Property and Shares

This is where it gets expensive if you’re not prepared.

When an NRI sells property in India, the buyer is legally required to deduct TDS at 20% (for long-term gains) or 30% (for short-term gains) on the entire sale value, not just the gain. This is a big deal, because if your actual tax liability is lower, you need to file a return to claim the refund, which can take time.

NRIs often come to us after the transaction has already happened, asking why so much TDS was deducted and how to get it back. The answer is: file your ITR, claim the credit, and wait for the refund. But ideally, before the sale, you should apply for a Lower Deduction Certificate from the tax department under Section 197. This reduces TDS at source and saves significant cash flow.

For equity and mutual fund investments, NRIs are taxed under Section 112A and 111A, with long-term gains above Rs 1.25 lakh taxed at 12.5% and short-term gains at 20%. The surcharge and cess on top of this matters, especially for higher-value portfolios.

5. NRIs Running a Business in India

If you have a business, a startup, or a partnership firm in India, your compliance responsibilities are significantly higher. You’re looking at GST registration and return filing if your business crosses thresholds, advance tax payments, transfer pricing provisions if there are cross-border transactions, and regular financial audits depending on turnover.

Many NRI business owners manage operations remotely or through a designated person in India. This works operationally, but from a tax standpoint, having a “permanent establishment” in India can expose your foreign entity to Indian taxes on business income. This is an area where proper structuring from the beginning saves enormous trouble later.

Working with experienced chartered accountant firms in Mumbai who understand cross-border structuring makes a real difference here. It’s not just about filing returns; it’s about building a compliant structure that holds up under scrutiny.

Common ITR Filing Mistakes NRIs Make

After working with NRI clients for years, certain patterns show up repeatedly:

• Filing under the wrong residential status
• Not disclosing NRO account interest
• Missing the ITR deadline and paying unnecessary late filing fees under Section 234F
• Not claiming DTAA benefits due to missing TRC
• Ignoring advance tax obligations on rental or capital gain income
• Filing ITR-1 when the correct form is ITR-2 or ITR-3

The ITR form selection alone is something that trips people up. If you have capital gains, foreign income, or business income, ITR-1 is simply not the right form, and submitting the wrong form means a defective return notice from the department.

Why Getting Professional Help Actually Saves Money

We know the instinct is to save money by filing yourself. There are online portals, CA aggregator apps, and YouTube tutorials that make it look straightforward. For a salaried resident Indian with simple income, that might work. For an NRI with property income, investments, TDS credits, and potential DTAA claims, the risk of doing it yourself is real.

A professional review does more than just file your return. It checks if you’re overclaiming or underclaiming deductions, ensures your TDS credits actually match what’s reflected in Form 26AS, identifies whether a Lower Deduction Certificate would help on upcoming transactions, and flags any notices or demands pending on your PAN that you may not be aware of.
