Shipping costs/ 1099k/ deduction
Hello-
New-ish business owner here. The gross income reported on my 1099-K's (multiple sources) is much more than I ever saw deposited in my bank account. It includes costs such as seller fees, shipping costs and marketing costs. My question is mostly aimed towards shipping costs. When I enter the shipping fees (approx $25,000), it is only deducting around $7,000 from my federal tax due. Why is this? I never see a dime of those shipping monies. Why am I paying tax on "income" I have never seen? Is there a way to enter this so I'm not charged tax on money I never saw?
Thank you for any help.
