questions for ecommerce sellers

Writeoffs

Is Cost of Goods Sold a Tax Deduction?

Yes, effectively the largest one most ecommerce sellers have. Cost of goods sold subtracts from gross receipts before profit is even calculated, so every dollar of product cost reduces taxable income. The timing rule is the catch: COGS is deducted in the year the unit sells, not the year you bought the stock.

→

Can Ecommerce Sellers Write Off Ad Spend?

Yes. Advertising is a fully deductible business expense under IRC Section 162, so 100% of your Meta, Google, TikTok, and Amazon ad spend reduces taxable profit. Influencer fees, UGC creators, agency retainers, and email platform costs count too. It goes on Schedule C line 8 in the year the cost belongs to.

→

How Is Inventory Taxed for Ecommerce Sellers?

Inventory is not deducted when you buy it. The cost sits on your books as an asset and becomes a deduction, called cost of goods sold, only in the year each unit sells. A $30,000 stock order deducts nothing by itself; the write-off arrives sale by sale as those units ship to customers.

How Do Ecommerce Sellers Pay Themselves?

Most ecommerce sellers pay themselves with an owner's draw: a simple transfer from the business account to a personal account. The draw itself is not taxed and not deductible; you owe income tax plus 15.3% self-employment tax on the store's entire net profit either way. S corp owners run payroll instead.

→

What Is Sales Tax Nexus for a Shopify Store?

Sales tax nexus is a connection to a state that obligates your Shopify store to register, collect, and remit that state's sales tax. You get it physically, through location, staff, or stored inventory, or economically, by crossing a state's sales threshold, commonly $100,000 in annual sales into that state.

→

Entity

Should an Amazon Seller Form an LLC?

Usually yes, once the store has real sales, but for liability, not tax savings. Amazon does not require an LLC, and a single-member LLC changes nothing about your taxes: you still file Schedule C and pay 15.3% self-employment tax. The LLC shields personal assets if a product injures a customer.

→

Forms

Does Shopify Send a 1099-K?

Yes, if you use Shopify Payments. Shopify issues Form 1099-K reporting your gross card sales to you and the IRS once you cross the federal reporting threshold, which has moved in recent years, so check current IRS guidance. If checkout runs through PayPal or Stripe instead, that processor issues its own 1099-K.

→

Quarterly

Do Shopify Store Owners Pay Quarterly Taxes?

Yes. If your Shopify store is a sole proprietorship or LLC and you expect to owe $1,000 or more in tax for the year, the IRS expects four estimated payments on Form 1040-ES, due April 15, June 15, September 15, and January 15. Nothing is withheld from Shopify payouts, so the store owner pays directly.
