Its that Taxing time of year.

[Ken Latchers]

As its that time of year (in the USA at least), i found this (among many) good summary about when you have to pay self employment tax or not. Generally if you average 7 or fewer nights or 8-30 nights and provide "substantial" services such as tours, house cleaning during a stay, meals, etc you DO have to pay self employment tax.

Kudos to this CPA site (tarlow. com/2018/01/02/tax-ramifications-short-term-rental/):

"When property is rented for short periods, special (and sometimes complex) taxation rules come into play, which can make the rents excludable from taxation; other situations may force the rental income and expenses to be reported on Schedule C (as opposed to Schedule E).

If you have been renting your home or second home for short periods of time, here is a synopsis of the rules governing short-term rentals so you can prepare yourself for the upcoming tax season.

• Rented for Fewer Than 15 Days During the Year: If you rent your property for fewer than 15 days during the tax year, the rental income is not reportable, and the expenses associated with that rental are not deductible. However, interest and property taxes are still deductible as itemized deductions on your Schedule A.
• Rented for an Average of 7 Days or Less: Under normal circumstances, rentals are treated as passive activities, which are reported on a Schedule E, and net profit from the rental activity is not subject to self-employment tax. But the special rules treat short-term rentals averaging 7 days or less as a trade or business similar to that of a hotel or motel, with the income and expenses reported on Schedule C, and the profits are subject to both income tax and self-employment tax.
• Rented for an Average of 8 to 30 Days: Even rentals for longer than 7 days are treated as a trade or business when substantial personal services are provided to the short-term tenant. Substantial services are those that are primarily for your tenant’s convenience, such as regular cleaning, changing linen, or maid service. Substantial services do not include the furnishing of heat and light, the cleaning of public areas, trash collection, and such.
  When extraordinary services are provided, the rental is treated as a trade or business and reported on Schedule C regardless of the average rental period. However, it would be extremely rare for this to apply to short-term rentals of your home or second home.
• Exception to the Significant Services Rule – If the personal services provided are similar to those that generally are provided in connection with long-term rentals of high-grade commercial or residential real property (such as the cleaning of public areas and trash collection), and if the rental also includes maid and linen services at a cost of less than 10% of the rental fee, then the personal services are neither significant nor extraordinary for the purposes of the 30-day rule.

A loss from this type of activity, even when reported on your Schedule C as a trade or business, is still treated as a passive activity loss and can only be deducted against passive income. The $25,000 loss allowance that applies to some Schedule E rentals is not available for rental activities reportable on Schedule C.
