At tax time, can you claim anything like storage fees etc?

Also does Amazon send a t slip to sellers?

Also do people find when doing taxes they have to pay or get a refund?

Thank you

Yes, all Amazon fees are deductible business expenses.

Amazon doesn’t send a T-slip, you’re responsible for tracking your own income and expenses. Download your monthly payment reports from Seller Central, that’s your record.

Whether you owe or get a refund depends entirely on your profit margins and what you paid in estimated taxes throughout the year. Most sellers owe if they haven’t been making quarterly installments.

Consult an accountant.
