Itemized business expenses are a set of costs related to the operations of a business. These can include a wide range of things like utilities, rent, office supplies, insurance, salaries, travel and training costs, marketing expenses, and more. When it comes to tax time, it’s important to make sure you have an accurate record of all your itemized expenses so you can take full advantage of all the deductions allowed by law. Taking the time to carefully document each and every one of these expenses can save your business money over the long run – so keep careful track of your costs!
