International Taxation in India: A Guide to DTAA, Cross-Border Transactions & Tax Compliance

1. What International Taxation Consultants in India Are Asked to Decide

International Taxation Consultants India are usually instructed when an Indian company is about to pay a foreign vendor, a foreign group is selling into India, or a family has income that two countries may both tax. The decision is which statute applies, which article of a Double Taxation Avoidance Agreement applies, whether tax is withheld before the bank releases the money, and whether the foreign enterprise has a taxable presence here.

The Income-tax Act, 2025 came into force on 1 April 2026. Income up to 31 March 2026 remains under the Income-tax Act, 1961. Contracts and bank checklists still say section 90, Form 10F and Form 15CA, so the table maps those names to the 2025 Act and the Income-tax Rules, 2026. The Act, the Rules and the notified treaties are on the Income Tax Department website. Residential status, slabs and capital gains for a non-resident are in the NRI taxation guide. NRE and NRO remittances are in the earlier Form 15CA note. Inbound share capital is the FEMA note.

2. Double Taxation Avoidance Agreement: Section 90 and Section 91 Relief

A Double Taxation Avoidance Agreement is a treaty the Central Government notifies with another country. Section 159 also covers a notified agreement between a specified association in India and one in a specified territory, which is what section 90A used to describe. The purposes in section 159(3) include relief where both countries have taxed the income, avoidance of double taxation, exchange of information, and recovery of tax. The avoidance limb is drawn so that the treaty does not become a path to non-taxation through evasion or avoidance, including treaty-shopping for the benefit of a resident of a third country.

Where the agreement applies, section 159(4) applies the Act to the extent it is more beneficial to that person. The comparison is item by item: a dividend article and a royalty article can differ, and both change with the country. Section 159(6) keeps Chapter XI, the general anti-avoidance rule, in force even where it is less beneficial than the treaty. Section 91, now section 160, is a separate credit. It is for a resident of India who has paid tax in a country with no agreement under section 159, on income that accrued outside India and is not deemed to accrue in India, at the Indian rate or the foreign rate, whichever is lower. An NRI’s claim to a treaty rate on Indian income is in the NRI guide.

3. DTAA Tax Benefits in India: Tax Residency Certificate and Form 10F

DTAA tax benefits in India for a non-resident rest on section 159(8). The person obtains a certificate of residence from the government of that country or specified territory, and provides the other particulars the rules prescribe. The certificate is the Tax Residency Certificate for the period of the income. Under the 1962 Rules the particulars were Form 10F, rule 21AB, for sections 90(5) and 90A(5). Under rule 75 of the 2026 Rules they are Form 41.

The Department’s note on Form 41 describes an electronic declaration, including for a non-resident with no PAN whose receipt is subject to withholding. The certificate and the foreign tax identification number are uploaded with it. Without them, the Indian payer deducts at the rate under the Act. An Indian resident who needs a certificate for a foreign tax authority applies in Form 42, formerly Form 10FA, and receives Form 43, formerly Form 10FB, from the Assessing Officer. That certificate is for use abroad. Hold the vendor’s certificate, and Form 41 or Form 10F as the year requires, before applying a treaty rate. International tax advice on a first payment is which article applies, and which form the portal is offering.

4. Cross-Border Taxation in India: Withholding and Form 15CA

Cross-border taxation in India, for the payer, is settled before the return. Tax is deducted where a sum paid to a non-resident or a foreign company is chargeable. Section 195 of the 1961 Act is section 393 of the 2025 Act. The rate is the rate in force, or the treaty rate where section 159(8) is met. Business profit, royalty, fees for technical services, interest and dividend are classified separately, even inside one contract.

The authorised dealer’s information form was Form 15CA. Under rule 220 it is Form 145, filed before the remittance. On the Department’s note, Part A is a chargeable remittance whose aggregate does not exceed ₹5 lakh in the tax year. Part B is a chargeable remittance above that amount, where a certificate under section 395(1) or 395(2) has been obtained from the Assessing Officer. Part C is a chargeable remittance above ₹5 lakh, supported by a chartered accountant’s certificate in Form 146, formerly Form 15CB. Part D is a remittance that is not chargeable to tax.

The Department’s note also takes some payments outside Form 145: an individual’s Liberalised Remittance Scheme transfer that needs no prior Reserve Bank approval, a remittance by an International Financial Services Centre unit, and a remittance under a specified Reserve Bank purpose code. Form 146 needs a UDIN, as notified by the Institute of Chartered Accountants of India, and one certificate is consumed by one Form 145. A missing or inaccurate Form 145 can attract a penalty of up to ₹1 lakh under section 462. Inaccurate information in Form 146 can attract up to ₹10,000 per certificate under section 463. File on the e-filing portal and give the acknowledgement to the bank. Under the 1961 Act the lower-deduction certificates are those in sections 195(2), 195(3) and 197. NRO remittances are in the remittance note.

5. Permanent Establishment Tax Rules in India

Permanent establishment tax rules in India sit beside a domestic source rule. Section 9 deems income from a business connection in India to arise here. That includes business through a person who habitually concludes contracts for the non-resident, or habitually plays the principal role leading to them, and it includes a significant economic presence. Significant economic presence can arise from transactions with persons in India, or from systematic solicitation of users, above thresholds the rules prescribe, with or without a place of business in India. Only income reasonably attributable to the Indian operations is included. Read the thresholds from the rule for the year.

For transfer pricing, section 173(c) includes a fixed place of business through which the enterprise carries on business. Each treaty then uses its own article, commonly a fixed place, often a dependent agent, and sometimes days of presence. Where that article taxes business profits only to the extent of a permanent establishment, an enterprise with none is outside Indian tax on those profits. Royalty and fees for technical services often remain taxable under their own article. With no treaty, section 9 is the test. Staff on site, a delivering warehouse, or a long spell of work in India can change a no-presence declaration.

6. Transfer Pricing, at the Level a Board Needs

Section 161 computes income from an international transaction, and an expense or interest arising from one, having regard to the arm’s length price. Section 173(a) defines that price as the price applied between persons who are not associated enterprises, in uncontrolled conditions. It is not used to reduce taxable income or to increase a loss against the books. Under section 163 an international transaction is between associated enterprises, at least one of them a non-resident, and it covers goods, intangibles, finance, services and restructuring. A deal with an unrelated party is included where the associated enterprise has a prior agreement, or sets the terms in substance.

Section 162 treats enterprises as associated where one participates in the management, control or capital of the other. A direct or indirect holding of shares carrying not less than 26 per cent of the voting power, at any time in the tax year, is one test. Loans, guarantees, board control and dependence on the other enterprise’s intangibles are others in the same section. Section 165 lists the methods: comparable uncontrolled price, resale price, cost plus, profit split, transactional net margin, and any other method the Board prescribes. Section 172 requires Form 3CEB one month before the return under section 263. Where section 172 applies, that return is due on 30 November. Safe harbour under section 167 and an advance pricing agreement under section 168 each need an application. Take the year to the international taxation desk with the invoices, before that month.

7. International Tax Consultants in Hyderabad: A Working Checklist

International tax consultants in Hyderabad see a repeating pattern. The invoice is booked, the treaty article is never chosen, and the bank asks for a certificate on the morning of the remittance. The order below keeps the payment, the form and the return on the same facts.

P. Ramesh & Associates does this from its Barkatpura office. The international taxation practice takes the treaty, the withholding and Form 3CEB. The NRI desk takes the individual’s return, which this article leaves to the NRI guide. Foreign investment and FEMA covers inbound share capital, as the FEMA article describes. Income-tax filing is the return that must match the deduction. The business advisory practice joins where the contract itself is the question. Consult Ramesh CA with the other party’s country, the nature of the payment, and whether a treaty claim is proposed.

• Classify the payment before approving the invoice: business profit, royalty, fees for technical services, interest, dividend, or a pure reimbursement.
• Collect the Tax Residency Certificate and Form 41, or Form 10F for income still under the 1961 Act, before using a treaty rate.
• Pick the part of Form 145, formerly Form 15CA, and obtain Form 146, formerly Form 15CB, where Part C applies. File before the remittance.
• Record whether the recipient has a permanent establishment or a business connection in India, and keep that note with the contract.
• Where section 162 is met, log the international transaction in the year and commission Form 3CEB for the date in section 173.
• Keep the portal acknowledgement so the bank, the computation and the return describe one payment.
