Do I file Form W-8ECI for rent from my US property?
It depends on whether what you do with the property amounts to conducting a business in the US, rather than on the fact that the property is there. The certificate is for foreign persons whose US income arises from actually conducting business in the US, and many non-resident owners of US operating property are in that position. A single unit let on a long lease with an agent collecting the rent is a different case from a portfolio that is actively managed, let and improved. That question has to be answered before the form, because the form asserts the answer.
What does effectively connected with a US business actually mean?
In practical terms it means the income comes out of activity carried on in the US, not merely from an asset that happens to sit there. The certificate exists to say that the income is effectively connected with a US trade or business, and the consequence of saying it is that the income is taxed on a net basis on a return instead of being withheld on the gross amount. The label is not a choice you make on the form. It describes what is actually happening, and the activity behind it has to be capable of being described the same way if anyone asks.
Does giving Form W-8ECI commit me to filing a US return?
Yes, and this is the part clients do not expect. The certificate swaps flat gross withholding for net-basis taxation and a filing duty, and the two arrive together. You are telling the payer that the income belongs on a return, so the return has to be filed, with the income and the expenses in it. That is usually the better answer where there are real expenses to claim. It is a worse answer where there are not, because you take on an annual obligation and the compliance cost that goes with it in exchange for very little. Decide it as a whole, not one half at a time.
Will my US property manager stop withholding once it has W-8ECI?
That is the intended effect, for payments it makes after it holds a valid certificate. The manager is a withholding agent and carries its own exposure, so it will look at whether the certificate is complete and whether what it knows about the property is consistent with the claim being made. Expect questions where the activity looks passive. The certificate does not reach backwards over rent it has already paid you, so the sooner it is in place the less there is to recover afterwards. Ask for written confirmation of the date it accepted the form.
When is net-basis taxation worse than gross withholding?
When there is little to deduct and the records are thin. Net-basis taxation is attractive because the tax follows the profit rather than the receipt, but it only delivers that if the expenses exist and can be evidenced. Where the deductible costs are small against the income, you have exchanged a withholding you did not have to administer for a return you must file every year, and the tax may not fall by much. We work the comparison through on your own figures before the certificate is signed, because the filing duty is difficult to step back from once it has started.
Can a foreign company use Form W-8ECI for service income?
It can, where the services are genuinely performed as part of a business conducted in the US, because the test is about the activity rather than the type of payment. What matters is what the company does there: people, premises, the place the work is carried out and the way the contracts are performed. A company that simply invoices a US customer from abroad is not in this position, whatever the size of the payment. Where the activity is real, the net-basis route often suits it, since a business with staff and costs has expenses to claim.
Is dividend income from Indian shares taxable for an NRI?
Yes. Dividends are taxed in the shareholder's hands, and the paying company withholds on payment to a non-resident. The treaty can reduce that withholding, but only if the documents are with the company before it pays: a tax residency certificate from your country, Form 10F, and a PAN on the register. Without them the domestic rate applies and your route back to the difference is a refund claim on an Indian return. See residency certificates and Form 10F.
What are Forms 15CA and 15CB for?
They clear a payment out of India. Form 15CA is the remitter's declaration of the payment and the tax withheld on it; Form 15CB is an accountant's certificate on the taxability of the amount, the treaty article relied on and the correct withholding rate. The bank generally will not execute the transfer without them, in the categories where they are required. The work is deciding the rate correctly, because the certificate is the record of that decision. See 15CA and 15CB certification.
