Shopify Tax Accountant for Year-End Returns

A Shopify tax accountant prepares the income tax return for your store, and the form is rarely the hard part. The hard part is getting from Shopify payouts, a Form 1099-K and a year of stock purchases to a profit figure the return can rely on.

This page covers income tax preparation and year-end filing for Shopify sellers, mainly in the US. It doesn't cover sales tax or VAT returns, which a sales tax specialist files through the year, or the monthly bookkeeping every return depends on. Other countries have their own rules and deadlines, so work with someone qualified where you file.

Describe your store, your business structure and where your books stand, and request a quote for this year's return. Mention your sales channels and whether you hold inventory, because both change the price.

What to ask a Shopify tax accountant before you hire

Check they're qualified where you file. Ask which credential they hold and which states they prepare returns for. Rules and deadlines vary by state, and a seller based outside the US needs someone qualified in their own country.

Ask about product sellers specifically. Ask how many clients they prepare returns for who hold inventory, and what usually needs fixing when those clients arrive. Specific answers about payouts, stock counts and processor forms beat general reassurance.

Ask what they want from you. The right answer is reconciled books, not a download of your payouts. If your books aren't reconciled, a good preparer says so and quotes the bookkeeping separately rather than building the return from bank deposits.

Ask how they handle the 1099-K. They should reconcile it to your gross sales, refunds and fees before the return is prepared, and ask whether other processors or marketplaces sent forms as well. A preparer who takes the form's total as your sales figure hasn't worked with many online sellers.

Get the scope in writing. Federal and state returns, which entity, whether next year's estimated payments are included, and whether answering a letter from the IRS or a state about this return is covered or billed separately.

Book before your year end. Engaging someone before the year closes, and before filing season fills their calendar, leaves time to count stock and discuss your structure while it can still change.

Treat these as warning signs. A promised refund or tax saving before they've seen your numbers. No questions about inventory. No clear answer about who will sign the return.

What your tax accountant needs from your Shopify store

Closed, reconciled books. Twelve months where every payout is reconciled to gross sales, fees, refunds and chargebacks. A return built from bank deposits starts from the wrong number. If the books aren't done, bookkeeping comes first.

Inventory and COGS at year end. A stock count or valuation at your year-end date and cost of goods sold for the year, built from cost per item plus freight and duty. How inventory is treated on the return is your accountant's call.

Your 1099-K, matched to the books. The total on the form rarely equals the sales line in your books. Reconcile it to gross sales, refunds and fees, and include forms from any other processors or marketplaces, so the return reflects what you kept rather than everything that passed through.

Sales tax kept out of income. Sales tax you collected belongs to the state. If it's sitting in revenue, the books need correcting before the return is prepared.

Your structure and this year's payments. Your structure decides which return is filed: sole proprietor, single-member LLC, partnership, S-corp or C-corp, including any tax election an LLC has made. Bring records of any estimated payments made during the year, and ask whether your structure and next year's quarterly payments still fit your profit.

Categorised ecommerce costs. Shipping, packaging, apps and ad spend, with invoices. Your accountant decides what's deductible.

Outside the US the same inputs matter, but the forms, rates and deadlines differ.

How much does an ecommerce tax accountant cost?

Tax preparation is priced per return, and your business structure decides which return you need. Typical US ranges:

Sole proprietor or single-member LLC return

$300 – $1,500

Per year, return with business schedule

S-corp or partnership return

$1,000 – $3,500

Per year, business return

Tax professional

$130 – $250

Per hour, middle 50% of US tax pros

A sole proprietor or single-member LLC usually files a personal return with a business schedule, which sits at the lower end. S-corps and partnerships file a separate business return, which costs more. Planning sessions and replies to notices are usually billed by the hour.

The state of your books moves the price most. Unreconciled payouts or a missing stock count mean clean-up before the return, billed as extra hours or as separate bookkeeping. Returns in several states, several sales channels and more than one owner add time too. Send last year's return and your current books with your request.

Frequently asked questions about ecommerce taxes

What should I do with my Shopify 1099-K?

Pass it to whoever prepares your return, together with your books. Shopify Payments issues Form 1099-K to US merchants above the federal threshold of more than $20,000 and more than 200 transactions, a threshold restored in 2025. Some states set lower thresholds, so check what applies where you file. Treat the form as a figure to reconcile, not one to copy onto the return.

Do I need an ecommerce CPA, or will any tax preparer do?

A CPA isn't the only qualified choice, but ecommerce experience matters. The return itself is standard; the inputs aren't. A preparer who works with product sellers will ask about inventory, the 1099-K and sales tax in revenue without prompting. For a small single-member business with clean books, a capable general preparer can be enough. With inventory, several channels or an S-corp, pick someone who does this work every year.

Are online business taxes different from other small business taxes?

The income tax rules are broadly the same; the paperwork isn't. Online sellers deal with payouts net of fees, forms from payment processors, stock spread across locations, and sales tax to collect in other states. That last one is a separate return, handled by a sales tax specialist. Your income tax preparer needs clean figures from all of it.

Is an ecommerce tax advisor the same as a tax preparer?

Not quite, though one person often does both. A preparer works backwards from the year just ended and files the return. An advisor works forwards: your business structure, estimated payments and the tax effect of big decisions such as a large stock purchase or taking on a partner. If you only talk to your accountant at filing time, you're buying preparation, not advice.

What about ecommerce taxes outside the US?

Every country has its own income tax rules, forms and deadlines. UK businesses report to HMRC, for example, and each EU country runs its own system. Work with someone qualified in the country where your business is based, and keep VAT separate: it has its own registrations and filing schedule, often with a different specialist. The inputs are the same as in the US: reconciled books, a year-end stock figure and clean records of fees and refunds.

Can I file my own return and only outsource the books?

Many small sellers do. The Shopify-specific mistakes mostly happen in the books, so if those are reconciled, a simple return is manageable for some owners. Once you hold significant stock, have partners or an S-corp, or the 1099-K won't reconcile to your sales, a professional usually earns the fee.
