Introduction
Form 10F is a supplementary declaration that eligible non-residents use to provide the information needed to support a claim for benefits under an applicable India tax treaty. It's one piece of a larger documentation puzzle, not a standalone application.
This guide is written for Australian residents, Australian businesses, NRIs, foreign investors, and other non-residents earning income from India, whether that's dividends, interest, royalties, consulting fees, or capital gains. Getting the paperwork right affects how much tax gets withheld at source and whether your treaty claim holds up under review.
Here's the complication for 2026: India's new Income-tax Act, 2025 came into force on 1 April 2026. The tax department has flagged that Form 10F is being replaced by Form 41 for income governed by the new Act.
Which form applies to you depends on the tax year your income falls into. Confirm the current form name and process on the Income Tax Department's e-filing portal before you submit anything. This guide walks through who must file, what information to include, and how the 2026 transition affects your filing.
Key Takeaways
- Form 10F supports DTAA claims but never replaces a valid TRC or India-Australia DTAA eligibility check.
- Non-resident individuals, companies, partnerships, and trusts earning Indian-source income may all need to file.
- Online filing involves portal registration, identity and tax details, document uploads, and e-verification.
- Confirm whether your income year falls under Form 10F or the new Form 41 regime before filing.
What Is Form 10F and How Does It Support DTAA Benefits?
Form 10F is a self-declaration that fills gaps your Tax Residency Certificate leaves open. Section 90(4) of India's Income-tax Act, 1961 requires a non-resident claiming DTAA relief to obtain a TRC from their home tax authority.
Section 90(5) adds a second requirement: prescribed additional information the TRC alone often doesn't cover. This includes tax status, nationality, foreign tax identification number, and the exact period the TRC covers (Rule 21AB of the Income-tax Rules, 1962).
Form 10F vs the Tax Residency Certificate
| Document | What It Does |
|---|---|
| TRC | Issued by the Australian Taxation Office; evidences that you're a tax resident of Australia for a given period. |
| Form 10F | Supplements the TRC with particulars the certificate doesn't itself contain, so the Indian payer and tax department can match your claim against treaty conditions. |
Neither document, by itself, guarantees a reduced withholding rate, exemption, or refund. Eligibility still depends on your actual residence status for the year, the type of income involved, beneficial ownership where the treaty requires it, any permanent establishment position, and the specific treaty article covering that payment.
In practice, a correctly filed Form 10F helps the Indian payer apply the treaty rate rather than the higher domestic rate at source, and it backs up the treaty claim you later make in your Indian tax return.
It's separate from your PAN application, any non-permanent-establishment declaration, lower-withholding certificate requests, and the ITR itself. Each serves a different purpose, even though they often get submitted around the same time.
The department's own guidance maps old Form 10F references (Sections 90(5)/90A(5), Rule 21AB) directly to new Form 41 references (Section 159(8), Rule 75) under the Income-tax Act, 2025, which came into force on 1 April 2026. Which form applies to you depends entirely on the tax year.
Who Needs Form 10F and Why Does It Matter for Australian Residents?
Form 10F is part of the paperwork Australian residents use to support India–Australia DTAA relief on Indian-source income. Likely filers include:
- Australian individuals working as consultants or contractors for Indian clients
- Australian companies and partnerships receiving Indian business income, royalties, or fees
- Trusts and investment vehicles holding Indian securities or earning dividends and capital gains
- NRIs and OCIs now based in Australia who still hold Indian bank interest, rental income, or investments
Each income type sits under a different article of the India-Australia DTAA, and treating all Indian-source income the same way is a common mistake.
| Income type | Relevant DTAA article |
|---|---|
| Business profits | Article 7 |
| Dividends | Article 10 |
| Interest | Article 11 |
| Royalties and technical services | Article 12 |
| Capital gains | Article 13 (Alienation of Property) |
Matching income to the right article is only the first step. Check the treaty's residence and permanent establishment tests (Articles 4 and 5) against your specific payment before you assume a reduced rate applies.
Multi-tier trusts and fiscally transparent partnerships often need extra scrutiny. Treaty residence may have to be evidenced at the ultimate-investor level rather than the entity level.
What happens without proper documentation?
Skip Form 10F or related treaty paperwork—or get it wrong—and the Indian payer typically has little choice but to apply domestic withholding instead of the treaty rate. That can mean:
- A larger upfront deduction at source
- Chasing a refund through your Indian tax return
- Processing delays or follow-ups from the Indian tax department
Dividends, interest, and royalties paid to Australian residents have historically sat around a 15% treaty rate under this DTAA. Confirm the current applicable figure for your income type and year before relying on it.
How to File Form 10F Online in 2026
Before you start, confirm three things: whether Form 10F or Form 41 applies to your specific tax period, what the e-filing portal's current instructions say, and who's permitted to file (you, an authorised representative, or someone acting on your behalf).
Income relating to FY 2025-26 and earlier (AY 2026-27 and prior) still falls under the old Form 10F regime, even if you're filing after 1 April 2026.
Step 1: Confirm treaty eligibility and gather your Australian documents
- Verify your Australian tax residence for the relevant period and get the matching certificate of residency from the ATO. Individuals use form NAT 75441; companies, trusts, and other entities use NAT 75442.
- Check that your certificate's name, address, tax identification details, and covered period match what you're about to submit in India.
- Identify the Indian income type, your expected payer, the relevant DTAA article, your PAN if you have one, and whether a permanent establishment question needs a closer look.
The ATO aims to process certificate-of-residency requests within 50 days, though it doesn't guarantee that timeline. Apply through ATO online services or by mail well ahead of your first Indian payment.
Step 2: Register on the correct portal route
PAN isn't always mandatory. The current Form 41 manual sets out a separate non-resident login (NR ID) for filers without a PAN who aren't otherwise required to hold one. Check which category fits you rather than assuming the general PAN-based registration applies.
You'll typically need:
- Foreign identification details (passport, company registration number, or equivalent)
- Incorporation or identity documents for entities
- Current address proof
- Key-person details for companies or trusts
- A working mobile number and email address for verification
Step 3: Enter details, attach documents, verify, and submit
Fields commonly requested include your particulars, foreign address, country of residence, foreign tax identification number, residency period, nature of the Indian income, the relevant treaty provision, and PAN details where applicable.
The current portal path runs through e-File, Income Tax Forms, File Income Tax Forms, Forms as per Income Tax Act 2025, then Form 41, with Part A covering applicant particulars and Part B covering residential information.
Upload your TRC along with any other requested declaration. File-format, size, translation, and certification requirements are shown on the portal at the time of filing, so don't rely on last year's specifications.
Verification depends on your login type:
- PAN login: electronic verification code (EVC) or a registered, unexpired digital signature certificate (DSC)
- NR ID login (no PAN): one-time passwords sent to your registered email and mobile number
Step 4: Save your evidence and brief your Indian payer
Download the acknowledgment once submission is confirmed, and keep the form plus attachments on file. Share the relevant evidence with your Indian payer before payment, if you want them to apply the treaty rate rather than the domestic one.
This is where many Australian clients ask for support, matching a TRC application to the right DTAA article and getting the Indian-side paperwork filed correctly before a payment goes out.
VJM Global works with foreign businesses and non-residents on this kind of treaty documentation review and India-side coordination, though no adviser can guarantee acceptance or a particular tax outcome.
2026 Document, Timing, and Error-Prevention Checklist
Documents to have ready:
- Valid Australian TRC covering the right period
- Foreign tax identification number or equivalent
- Identity or incorporation records
- Current address information
- PAN details, if available or required
- Income and payment records matching the treaty claim
- The specific treaty article you're relying on
- Non-PE or beneficial-ownership evidence, where relevant
Timing:
- Apply for your TRC early. ATO processing takes weeks, not days.
- File before your first relevant Indian payment where possible.
- Coordinate separately with each Indian payer if you have more than one income stream.
- Refile when the tax year, income stream, or your details change — current guidance treats this as once per tax year, not a lifetime filing.
Accuracy checks before you submit:
- Names, addresses, and tax numbers match across the form, TRC, invoices, and contracts
- Residency periods line up with payment dates
- Entity status is described consistently throughout
- Income description and DTAA article reference match the actual payment
Common portal problems:
- Non-resident registration failures
- Foreign mobile number or OTP delivery issues
- DSC expiry
- Unsupported file formats or oversized documents
- Mismatched "My Profile" details versus the form itself
Raise any of these through official portal support channels and keep a record of the error.
2026 legal-status check: The Indian tax department has confirmed Form 41 (old Form 10F) as the applicable form under the Income-tax Act, 2025, with Rule 75 replacing old Rule 21AB.
Whether this applies depends on which tax year your income falls into. Older-year claims may still need the old Form 10F process.
Conclusion
Form 10F, or its 2026 successor Form 41, is one part of a broader DTAA documentation chain, not a standalone entitlement to treaty relief. The TRC, the correct treaty article, accurate income classification, and consistent payer records all have to line up before a reduced withholding rate or treaty-based ITR claim holds up.
For Australian residents and businesses earning Indian income, that means checking the current rules each filing season rather than reusing last year's paperwork. If you're dealing with a complex structure, a large payment, or a tight deadline, get a second opinion before you submit.
