Airbnb Receipt, Confirmation Code SMYWAN Form

You are required to complete a Form W-8BEN if you are a non-resident alien and earned Royalty income (in this case) from a US-based source.The purpose of the form is to alert the IRS to the fact you are earning income from the US, even though you are not a citizen or a resident of the US. The US is entitled to tax revenues from your US-based earnings and would, without the form, have no way of knowing about you or your income.To ensure they receive their “fair” share, they require the payor to withhold 30% of the payment due to you, before issuing a check for the remainder to you. If they don’t withhold and/don’t report the payment to you, they may not be able to deduct the payment as an expense, and are subject to penalties for failing to withhold - not to mention forced to pay the 30% amount over and above what they pay to you. They therefore will not release any payment without receiving the Form W-8BEN.Now, Nepal happens not to have a tax treaty with the US. If it did and you were subject to Nepalese taxes on that income, you could claim a credit for the taxes paid to another country, up to the entire amount of the tax. Even still, you are entitled to file a US Form 1040N, as the withholding is charged on the gross proceeds and there may be expenses that can be deducted from that amount before arriving at the actual tax due. In that way, you may be entitled to a refund of some or all of the backup withholding.That is another reason why you file the form - it allows you to file a return in order to apply for a refund.In order to complete the form, you can go to the IRS website to read the instructions, or simply go here: https://www.irs.gov/pub/irs-pdf/...
