I started an Airbnb at the end of 2024 but had no guests, can I still deduct the expenses incurred to get it up and running

You can deduct ordinary and necessary expenses you incur to place your rental property in service, manage it, and maintain it, even if the property is temporarily vacant.

• Costs you incur to place the property in service, manage it, and maintain it generally are deductible. Even if your rental property is temporarily vacant, the expenses are still deductible while the property is vacant and held out for rent.
