Our calculator shows income before tax, and that is a deliberate choice: tax treatment depends on your country, your state, how you use the property and your other income. This guide explains the main ideas in plain language for hosts in the United States, based on IRS publications. It is an introduction, not tax advice, and the rules may change, so read the current IRS pages named below or ask a qualified tax professional.
The calculator subtracts the platform fee and your monthly fixed costs from gross revenue. It does not subtract income tax, self-employment tax, or the effect of depreciation and deductions. If the calculator shows $1,721 per month, that is about $20,652 over twelve months of identical results, but the amount you keep depends on how the income is reported. Treat the result as a pre-tax operating figure.
IRS Publication 527 (Residential Rental Property) explains that if you rent out a property that you also use as your home for fewer than 15 days during the year, you do not include the rent in your income, and you also cannot deduct rental expenses for that activity. For example, a homeowner who rents a house for 10 nights at $300 per night during a local event receives $3,000, and under this rule that amount is not reported as income. Once the rental reaches 15 days or more, the normal rental reporting rules apply. Check the current publication for details and conditions before relying on this rule.
Publication 527 says you use a dwelling unit as a home if your personal use exceeds the greater of 14 days or 10% of the days you rent it to others at a fair rental price. Here is a worked example. Suppose you rent a vacation cottage for 200 days. Ten percent of 200 is 20, and 20 is greater than 14, so the limit is 20 days. If your family stays 25 days, you passed the limit and the property counts as a home for that year, which limits how much of your expenses you can deduct. If your family stays 18 days, you stayed under the limit. Days when you work substantially full time repairing or maintaining the property generally do not count as personal use, but read the publication for the full definitions.
Rental income is generally reported on Schedule E (Supplemental Income and Loss). However, Publication 527 explains that if you provide substantial services mainly for the convenience of your guests, such as regular cleaning during a stay or maid service, the activity can be treated as a business and reported on Schedule C (Profit or Loss From Business). In that case you may also owe self-employment tax using Schedule SE. Publication 925 (Passive Activity and At-Risk Rules) lists an exception for rentals where the average period of customer use is 7 days or less, meaning such a rental is not automatically treated as a passive rental activity. Many short-term stays are shorter than 7 days on average, so this matters for Airbnb-style hosting. Whether providing a cleaning between stays counts as a substantial service is a question of facts, and the IRS publications explain the distinction. This is the type of question where a short consultation with a tax professional pays for itself.
For ordinary rental real estate, Publication 925 describes a special allowance of up to $25,000 of loss for people who actively participate, which phases out as modified adjusted gross income rises. If your short-term rental falls under the 7-day average exception, those rental-specific rules are replaced by the general passive-activity tests, such as whether you materially participate. Do not assume a loss will offset your wages without checking.
Income tax is only one layer. Many cities, counties and states charge lodging or occupancy taxes on short-term stays, and some platforms collect and pay them for the host in certain places while in others the host must register and remit. These taxes are locality-specific, so this site does not state any rates. Ask your local tax or licensing office what applies to your address.
Use the calculator to decide whether the monthly figure is attractive, then reduce it for taxes using your own situation. If your estimated net is $1,721 and you expect to set aside a share for tax, discuss the right percentage with an accountant instead of using a rule of thumb from the internet. For the costs side, see costs hosts forget, and for the income side see how to estimate your income.
