Deducting personal purchases as business expenses

[KCM95]

I recently created an LLC. I began setting up the business while waiting for the state's approval. I purchased education to learn all about the business. I also purchased a phone system, call center service,  virtual mailbox, CRM software, and spent a good amount of money on marketing. All these expenses were exclusively for the business but purchased with my personal bank account because I didn't have a business bank account as I was waiting for the state's approval of my LLC. Am I still able to write these off as business expenses when I file my taxes even though I purchased them personally? If I can, would these write-offs be on my personal taxes or my business taxes?

A single-member LLC is a disregarded entity for federal income tax purposes and indistinguishable from you; it is treated as a sole proprietorship.

You will file a Schedule C and report all of your income and expenses, business account or not.
