Documents Required for NRI Tax Filing in India (Checklist)

A software engineer in California called us last Tuesday, three days before the July 31 filing deadline.

"Ankur, I've been trying to file my ITR for two weeks. Every time I think I'm done, the portal asks for another document I don't have. TDS certificate from my tenant, some Form 16B for property sale, capital gains statement from my mutual fund. I don't even know what half these documents are or where to get them. Can you just tell me exactly what I need so I can finish this?"

We see this panic every filing season at Belong.

NRIs start filing their tax returns in mid-July. They realize halfway through that they're missing critical documents. Bank statements from six months ago. Property tax receipts they never saved. TDS certificates their tenant forgot to provide.

You search online for "documents needed for NRI tax filing." You find generic lists: PAN card, Aadhaar, bank statements. But nobody tells you which bank statements (savings account? NRO? All of them?). Nobody explains which certificates matter for your specific income type.

You spend hours hunting through emails, calling your property manager in India at odd hours, requesting duplicate statements from banks. Meanwhile, the deadline creeps closer.

Here's what we've learned helping thousands of NRIs file returns at Belong: the document requirement isn't complicated once you map it to your income sources. Rental income needs specific documents. Capital gains needs different ones. Get this mapping right upfront, and filing takes 30 minutes instead of 30 hours.

This guide gives you the complete checklist organized by income type.

We'll cover mandatory documents, optional but helpful ones, how to get missing documents quickly, and how our team handles all the document chaos for you.

The universal documents: What every NRI needs

Before we dive into income-specific documents, let's cover what everyone must have.

Core identification documents

PAN card:

Permanent Account Number. Mandatory for all tax filings. If you don't have PAN, apply immediately (takes 2-3 weeks).

Aadhaar card:

Not mandatory for ITR filing. But required for Aadhaar-based verification (simplest verification method). If you have it, link PAN with Aadhaar before filing.

Passport:

Proof of NRI status. Copy of passport showing visa stamps (proves you were abroad). Useful for determining residential status (182-day calculation).

Bank account details:

Account number where refund should be credited (NRO account typically). IFSC code. Bank name and branch.

Form 26AS: Your TDS summary

What it is:

Consolidated statement showing all TDS deducted against your PAN. Banks, tenants, companies report TDS to tax department. Form 26AS consolidates it all.

Why it's critical:

Shows rental TDS, NRO FD TDS, dividend TDS, capital gains TDS. Pre-fills most TDS data in ITR (if correct). Helps you claim refunds accurately.

How to get it:

Login to income tax portal (incometaxindiaefiling.gov.in). Navigate to "e-File" > "Income Tax Returns" > "View Form 26AS." Download PDF for the relevant financial year.

What to check:

Match TDS amounts with your records. Ensure all deductors reported correctly. Flag mismatches before filing.

👉 Tip: Download Form 26AS before starting your ITR. It's your single source of truth for all TDS. If something is missing from Form 26AS but TDS was deducted, follow up with the deductor to file correction.

Previous year's ITR acknowledgment

If you filed ITR last year:

Keep acknowledgment (ITR-V) handy. Some fields auto-populate from previous year. Helps maintain continuity (carry forward losses, etc.).

If first-time filer:

Not applicable. But keep this year's acknowledgment for next year.

Address proof

Current residential address abroad:

Utility bill, rental agreement, bank statement (showing your foreign address). Needed for establishing NRI status.

Correspondence address in India:

Where tax department will send notices (if any). Can be your property address, parents' address, or CA's office.

Documents for rental income

If you earn rent from India property, you'll need specific documentation.

Rental agreement

What you need:

Copy of current rental agreement. Shows monthly rent amount. Tenant's name and PAN. Agreement start and end dates.

Why it's needed:

Proves rental income amount. Required if tax department scrutinizes your return.

If you don't have it:

Get copy from property manager or tenant. If informal arrangement (no written agreement), create month-wise rent receipts signed by tenant.

Form 16C: TDS certificate from tenant

What it is:

Certificate issued by tenant showing TDS deducted on rent.

When required:

If monthly rent exceeds ₹50,000, tenant must deduct 30% TDS. Tenant should issue Form 16C quarterly.

What it shows:

Rent paid each month. TDS deducted each month. Tenant's PAN and details.

How to get it:

Request from tenant. Or check Form 26AS (TDS should reflect there).

If tenant didn't provide Form 16C:

Check Form 26AS to verify TDS was deposited. If TDS was deducted but not deposited, follow up with tenant (they're liable). You still report rent and TDS (based on receipts and Form 26AS).

Property tax receipt

What you need:

Municipal tax payment receipt for the financial year.

Why it's needed:

Property tax paid is deductible from gross rent. Reduces your taxable rental income.

Example:

Gross rent: ₹6 lakh. Municipal tax paid: ₹15,000. Net rent: ₹5.85 lakh (before 30% standard deduction).

How to get it:

Online from municipal corporation website (most cities allow download). Or visit municipal office and request copy.

If you haven't paid property tax:

You can't claim this deduction. Pay immediately to reduce tax liability.

Bank statements showing rent credit

What you need:

NRO account statement showing monthly rent deposits. Covers entire financial year (April to March).

Why it's needed:

Proves rent actually received. Matches declared rental income. Useful if tax department asks for verification.

How to get it:

Download from net banking. Or request from bank branch.

Home loan documents (if applicable)

If you have home loan on rented property:

Home loan interest certificate from bank (shows interest paid during the year). Deductible up to ₹2 lakh under Section 24(b) in old tax regime.

Home loan principal repayment:

Not deductible from rental income. But can be claimed under Section 80C (if using old regime and haven't exhausted ₹1.5 lakh limit).

Understand rental income taxation.

Documents for capital gains

If you sold property, stocks, or mutual funds, you need detailed documentation.

For property sale

Sale deed:

Final registered sale deed. Shows sale price, buyer details, sale date.

Purchase deed:

Original purchase deed. Shows purchase price, purchase date. Needed to calculate capital gains.

Bills for major improvements (renovation, additions). Can be added to cost of acquisition (reduces capital gain).

Indexation calculation:

Cost Inflation Index (CII) for purchase year and sale year. Used to calculate indexed cost. CII values published by income tax department annually.

Exemption documents (if claiming Section 54/54F):

New property purchase deed (if bought another property). Or booking receipt and payment proof (if under construction). Or investment proof in NHAI/REC bonds (if claiming Section 54EC).

Contract notes:

TDS certificate:

If broker/AMC deducted TDS on capital gains. Should reflect in Form 26AS.

Dividend reinvestment records:

If you reinvested dividends in mutual funds, those become part of purchase cost. Reduces capital gains calculation. AMC statement usually shows this.

For equity delivery trades

Holding period proof:

Shows whether LTCG (>12 months) or STCG (≤12 months). Usually calculated in capital gains statement.

STT payment proof:

Securities Transaction Tax paid. Already included in contract notes. Needed to claim LTCG exemption (only STT-paid equity qualifies for 12.5% LTCG rate).

👉 Tip: Request capital gains statement from broker/AMC by mid-April (right after financial year ends). Don't wait till July. Statements take time to generate, and you want to review them carefully before filing.

How to get missing documents quickly

If you're missing something critical, here's how to recover.

Form 26AS is missing TDS

Possible reasons:

Deductor (tenant, bank, company) didn't deposit TDS with government. Or deposited but reported wrong PAN.

Fix:

Contact deductor immediately. Ask them to verify PAN used and deposit status. If they deposited correctly, TDS should appear in Form 26AS within 7-10 days of deposit.

If deadline is near:

File ITR based on actual TDS (even if not in Form 26AS). Attach deduction proof. Follow up separately to get TDS corrected.

Property tax receipt lost

Municipal corporations have online records:

Visit municipal website. Enter property ID or address. Download receipt copy.

If not available online:

Visit municipal office with property documents. Request duplicate receipt (may take 2-3 days).

Capital gains statement not provided by broker

Brokers are required to provide:

Login to broker portal. Navigate to "Tax" or "Reports" section. Download capital gains statement.

If portal doesn't have it:

Email broker's support. Quote your client ID and financial year. They should provide within 2-3 working days.

TRC for DTAA claims

If you need Tax Residency Certificate urgently:

UAE: Apply online at Ministry of Finance portal (takes 3-5 days). USA: Request IRS Form 6166 (can take 2-4 weeks, apply early). UK: Apply through HMRC online (takes 1-2 weeks). Singapore: Request from IRAS (takes 5-7 days).

If deadline is near and TRC delayed:

File ITR without DTAA claim (pay higher TDS). File revised return later with TRC to claim refund.

Common document mistakes NRIs make

We see these errors constantly.

Mistake 1: Not downloading Form 26AS before filing

The mistake: Starting ITR filling without Form 26AS. Guessing TDS amounts from bank statements.

Reality: Form 26AS is auto-populated source in ITR. If you don't verify it first, mismatches cause processing delays.

Fix: Download Form 26AS first. Match with your records. Flag discrepancies before filing.

Mistake 2: Missing property tax receipts

The mistake: Not claiming property tax deduction because receipt is lost.

Lost benefit: On ₹20,000 property tax: Saves ₹1,000-6,000 in tax (depending on slab).

Fix: Download from municipal website or visit office to get duplicate.

Mistake 3: Not requesting Form 16C from tenant

The mistake: Tenant deducted TDS but didn't provide certificate. You report TDS based on bank statement (guessing amount).

Reality: Mismatch between your claimed TDS and Form 26AS (if tenant reported wrong amount). Delays processing or triggers notice.

Fix: Always request Form 16C. If tenant delays, at least verify TDS in Form 26AS before filing.

Mistake 4: Not keeping capital gains calculation worksheet

The mistake: Reporting final LTCG/STCG number in ITR without detailed calculation backup.

Reality: If tax department scrutinizes, they'll ask for calculation details (buy price, sell price, indexation, expenses).

Fix: Maintain Excel worksheet or capital gains calculation document. Keep buy and sell contract notes.

Mistake 5: Forgetting foreign asset reporting

The mistake: Not filling Schedule FA because "I forgot" or "it's complicated."

Reality: If foreign assets exceed ₹50 lakh, non-reporting attracts penalty up to ₹10 lakh.

Fix: Create foreign asset inventory (bank accounts, property, stocks). Report in Schedule FA even if cumbersome.

Frequently Asked Questions

What if I don't have Form 16C from my tenant?

Check Form 26AS to see if tenant deposited TDS. If yes, report based on Form 26AS. If no, follow up with tenant (they're liable for non-deposit). Report rent and TDS based on receipts in ITR.

Can I file ITR without property tax receipt?

Yes, but you lose the deduction. Property tax paid reduces taxable rental income. Without receipt, you can't claim it. Try to get duplicate from municipal corporation.

How do I get Form 26AS if I don't have portal login?

Register on income tax portal using PAN. Create login credentials. Then download Form 26AS. If you're unable to register, contact our team for assistance.

What if my capital gains statement has errors?

Cross-verify with contract notes. If broker's statement is wrong, recalculate manually. Maintain your own calculation worksheet. Report accurate figures in ITR (you're responsible, not broker).

Do I need physical copies or are digital documents fine?

Digital copies (PDFs) are fine for filing ITR. But maintain physical copies for records. Tax department may ask for originals during scrutiny (rare, but possible).

What's the penalty for not reporting foreign assets?

If foreign assets exceed ₹50 lakh and you don't report in Schedule FA: Penalty up to ₹10 lakh under Black Money Act. Plus possible prosecution. Always report if threshold is crossed.

Can Belong help me collect missing documents?

Yes. We guide you through requesting certificates from banks, brokers, employers. We provide templates. We follow up on your behalf where possible.
