<prompt> Human: I have an etsy store that did well last year along with my traditional service business work.Im not an accountant, im terrible with numbers. Thats why I hire an accountant. I just got hit with a tax number that is 35 of my gross income. According to my personal understanding I should have almost a 50 deduction from my gross income for seller fees, shipping, refunds, sales tax, supplies, etc. Now im aware that there are certain business expenses that cant be 100 written off, but things like those that I list above should all be 100 writeoffs right? If you figure my net income is 50 of my gross than my tax rate would be 70 of my net...TL:DR are etsy expenses like shipping, seller fees, refunds, and sales tax 100 tax deductible? What about supplies that you use to make your products? Are those also 100 deductible?Assistant: Did you review the return in detail with your accountant?Did they explain your ordinary and necessary business expenses?Human: They havent given me a detailed anything, just an email with a federal and state number.  <response>: You need to understand every dollar on your returns. You, as the Taxpayer, are responsible for their accuracy.
