Tax & bookkeeping built for how e-commerce actually operates

E-commerce brings a specific set of tax and bookkeeping problems that a generalist accountant often misses: inventory that has to be valued correctly, sales tax obligations that can trigger in states you have never set foot in, and payment processor fees that need to be separated cleanly from actual revenue. Hasco Tax Advisors works with online sellers on Shopify, Amazon, Etsy, and direct-to-consumer platforms, handling the bookkeeping and tax details that are unique to selling online.

E-Commerce Tax Issues

The tax questions that come up specifically for online sellers

Sales tax nexus, the issue that catches most sellers off guard

Since the 2018 Supreme Court decision in South Dakota v. Wayfair, states can require you to collect sales tax once you cross a revenue or transaction threshold in that state, even with no physical presence there. Most sellers on Amazon FBA discover this the hard way, since Amazon's fulfillment network can create "physical nexus" simply by storing your inventory in a state's warehouse. We help identify where you actually have nexus and what needs to be registered before it becomes a multi-state compliance problem.

Inventory valuation and cost of goods sold

Your inventory on hand at year-end directly affects your taxable profit. Overstating or understating inventory value, a common error when it is tracked loosely in a spreadsheet, distorts your cost of goods sold and either overstates or understates your tax liability. We reconcile inventory records against your actual books rather than accepting a year-end estimate.

Marketplace facilitator laws

Many states now require marketplaces like Amazon and Etsy to collect and remit sales tax on your behalf automatically. This does not eliminate your filing obligations in every state, and the specifics vary. We help sort out which states are covered by marketplace facilitator collection and which still require your own registration and filing.

Bookkeeping Workflow

How e-commerce bookkeeping actually gets reconciled

Payment Processor Reconciliation

Shopify Payments, Stripe, PayPal, and Amazon payouts are reconciled against actual bank deposits, separating gross sales, fees, refunds, and chargebacks correctly rather than recording net deposits as revenue.

Inventory Tracking

Cost of goods sold is tracked against actual inventory levels, not estimated at year-end, so your margins reflect what actually happened, product by product.

Multi-Channel Consolidation

Sellers on multiple platforms, Shopify, Amazon, and Etsy simultaneously, get one consolidated set of books instead of three disconnected reports.

Sales Tax Liability Tracking

Sales tax collected is tracked as a liability, not revenue, and reconciled against what has actually been remitted in each registered state.

Frequently Asked Questions

E-commerce tax and bookkeeping, answered directly

Not automatically. You generally owe sales tax collection once you establish nexus in a state, either through physical presence (including Amazon FBA inventory storage) or by crossing that state's economic nexus threshold, typically based on revenue or transaction count. We review your actual sales data to identify where you have nexus.
Partially. Marketplace facilitator laws require platforms like Amazon and Etsy to collect and remit sales tax on marketplace sales in most states. Shopify does not do this automatically for your own direct store, since you are the seller of record there, not a marketplace. We help sort out exactly what is and is not covered.
Unsold inventory is an asset on your balance sheet, not an expense, until it is actually sold. Only the cost of inventory that was sold during the year reduces your taxable income through cost of goods sold. Accurate inventory tracking throughout the year prevents a distorted profit figure at tax time.
Yes. Multi-channel sellers are common, and we consolidate all platforms into one set of reconciled books, so you see one true picture of your business rather than separate, disconnected reports per channel.
Most online sellers start as an LLC and consider an S-Corp election once profit is consistent and clears a meaningful threshold, typically $45,000 to $60,000 in net profit. We review your specific numbers before recommending a structure.
