Can I write off a storage unit for business inventory?

The cost of renting a storage unit for business inventory is deductible as a business expense if the inventory is directly related to your business operations. This is applicable if the storage unit is used exclusively for business purposes, such as storing products, materials, or supplies that are part of your business inventory. However, if the storage unit is used for personal items or mixed-use, only the portion used for business can be deducted.
