NRI income tax preparation doesn't have to mean a panicked June. Here's how arriving organized — before your CA asks — makes the whole season smaller.

NRI Income Tax Preparation: The Calm Before Your CA Calls

There is a version of Indian tax season that is not stressful. Most NRIs have never seen it, but it exists — and NRI income tax preparation done a few weeks early is the entire difference.

The version most NRIs know looks like this: a low hum of dread in April, a mild panic in June, a cascade of CA emails in the last two weeks of July. The other version looks like this: a quiet hour in May, a single PDF handed to your CA by June 15, and a July 31 deadline that passes like any other Tuesday. The content of the returns is identical. What changes is the timing and the format of what you hand over.

This is about the second version.

Why the scramble happens (and it is not your fault)

NRI tax situations are genuinely fragmented. If you have an NRO savings account, a rental property in Pune, some capital gains from a Zerodha account, and an NRE fixed deposit, those are four separate income streams, each with its own TDS logic, its own certificates, and its own ITR schedule.

The Income Tax Department's Form 26AS shows TDS deductions across all of these — but it rarely matches the actual certificates your bank sends, because banks reconcile quarterly and 26AS pulls from deductors who file their TDS returns at different times. By the time you are scrambling to check these figures in late June, the window to chase your bank or your tenant for corrections is almost closed.

The scramble is a timing problem. The documents all exist. What is missing is a way to gather them before your CA asks.

The documents every NRI needs before June 15

If you can collect these before the middle of June, your CA can file your return in a day:

Form 26AS — Download from the Income Tax portal (incometax.gov.in) under your PAN. This is the master TDS ledger.
AIS (Annual Information Statement) — Also from the portal; a more detailed view added in 2024 that includes interest, dividends, and capital gains your institutions reported.
NRO interest certificates (Form 16A) — One per bank, per account. HDFC, ICICI, SBI — each should issue one after the financial year closes.
NRE FD interest certificate — Technically exempt from Indian tax, but your CA needs to see the figure to complete Schedule EI (Exempt Income).
Rental income details — Annual rent received, municipal taxes paid, and your tenant's TDS certificates (Form 16C) if they deduct under Section 195.
Capital gains statement — From your broker (Zerodha, HDFC Securities, etc.) — typically a downloadable CSV with acquisition dates, sale dates, and STCG/LTCG split.
DTAA documents — If you are claiming treaty relief on NRO interest: your Tax Residency Certificate (TRC) from your country of residence's tax authority, and a completed Form 10F.

Seven categories. Most of them are downloadable. Most of them take under five minutes to pull once you know where to look. The problem is that nobody tells you this until your CA is asking for them on July 10.

TDS reconciliation: the part that actually saves you money

Here is the part most NRIs skip: checking whether the TDS in Form 26AS matches the certificates your banks issued.

Your HDFC NRO account deducted ₹12,600 on ₹42,000 interest (30%). Does that exact figure appear in your Form 26AS? Sometimes yes. Sometimes the bank filed their quarterly TDS return late, and the amount in 26AS is slightly different — or not there at all. If the figure is missing from 26AS, your CA cannot take credit for it in your ITR without additional documentation.

This reconciliation — cross-checking your declared income and TDS against what Form 26AS and AIS actually show — is the single most time-consuming part of NRI filing. It is also the part most likely to uncover a genuine discrepancy worth chasing before July, not during.

If you are going to do one thing in May, let it be this: download your Form 26AS and AIS, list your expected TDS deductions by institution, and flag anything that does not match.

DTAA: understanding the one claim worth making

If you have NRO interest income and you are a tax resident in the US, UK, UAE, Canada, Singapore, or most other major countries, you likely qualify for DTAA (Double Tax Avoidance Agreement) relief under your country's specific treaty with India.

For US residents, India's Article 11 caps NRO interest taxation at 15% instead of the standard 30% TDS rate. If your bank deducted 30% — which they will by default — you are owed a refund of the excess 15 percentage points. On ₹42,000 of NRO interest, that is ₹6,300 back.

The claim requires: (1) a Tax Residency Certificate from the IRS or equivalent authority in your country, and (2) a filled Form 10F. These take some effort the first time. After the first year, you update the dates and figures and it takes twenty minutes.

Your CA will know the mechanics. Your job is to flag it early — ideally in May, when they have time to guide you on the documents, not in the last week of July.

What a CA-ready packet actually looks like

This is the concrete goal: a single PDF — or email with organized attachments — that your CA can open and immediately begin entering figures from.

It should contain:

Income summary by category (NRO interest, NRE interest, rental, capital gains, dividends)
TDS per source, reconciled against Form 26AS
Property details: address, rent received, municipal tax paid, loan interest if any, tenant TDS
DTAA position: which treaty, which article, what rate, whether TRC is attached
Advance tax payments made during the year (BSR code, challan number, amounts)

Your CA should not need to email you for any of these. Their job, when they receive this packet, is to enter the figures and file. Not to chase you for a Form 16A you forgot to download.

The fifteen-email CA thread that every NRI knows is not about complex taxes. It is about format — information your CA already knows they need, assembled too late and too scattered to use efficiently.

Starting before it feels urgent

The practical answer is: organize once, early, in the same app or folder every year. Know where your 26AS is. Know where your Form 16As live. Have your DTAA certificate somewhere you can find it in thirty seconds.

IndiaTax NRI is built around exactly this workflow — an on-device organizer that walks you through each income type, reconciles your 26AS entries against what you entered, runs a DTAA calculator for your country (twelve treaties currently covered), and exports a CA-ready PDF. No uploads, no accounts. Just your numbers in one place, in a format a CA can use.

If you also think about your Indian money as part of a broader picture — NRO savings, remittance flows, property values, net worth — you are not alone in wanting tools that make that clearer. The Make the money behave collection brings together apps built for exactly that: calm, private, no bank logins, no data harvesting.

One hour in May

That is the real ask. Not a complete overhaul of your approach to Indian finance. One hour in May, before the urgency hits, to pull the documents you already have access to and sort them into a shape your CA can use.

One hour in May buys a calm June, a fast July, and a filing that happens on your timeline, not your deadline's.
