Key Takeaways
- NYC e-comm owners get taxed three times on the same profit: federal, New York state, and New York City. Most DIY software misses NYC-specific deductions.
- Post-Wayfair (2018), you likely owe sales tax in more than just New York. An e-commerce CPA tracks your economic nexus state by state.
- The right entity depends on your profit and your city. S-Corps usually don’t work in NYC because of the city corporate tax. A single-member LLC is often cleaner.
- A real e-commerce CPA does three things: multi-state sales tax, monthly or quarterly bookkeeping, and year-end planning. Flat fee, no surprises.
The Problem With Most NYC E-Commerce Tax Prep
The biggest problem businesses have that profit hundreds of thousands or even millions of dollars is that they don’t plan for taxes. They don’t look at their financial statements on a monthly or quarterly basis and put money aside. So when April comes around, they have this big tax bill, and they don’t know how to catch up and start paying it.
E-commerce makes this worse. Your revenue is on Stripe, Shopify, PayPal, and Amazon. Your expenses are software subscriptions on five different credit cards. Your customers are in all 50 states. Your DIY software can’t handle K-1s, multi-state allocations, or inventory accounting.
As part of the Accountant Quality Control Review, we see a lot of returns that were self-prepared on these do-it-yourself software, and they just were not right for that type of return. We amend and clean it up fast before you get a notice from the IRS asking for more information or denying your refund.
What an NYC E-Commerce Accountant Actually Does
Multi-state sales tax
Post-Wayfair, states can require you to collect sales tax once you cross their economic nexus thresholds, even without a physical presence. For a Shopify or Amazon seller in NYC, that can mean collecting and remitting in 10+ states.
All you can do for right now is track whatever you can going forward. Start collecting and remitting going forward, and then be prepared in case you get a letter from a state in terms of previous taxes. We offer consultations on voluntary disclosure programs and look-back periods across several states.
Entity structure for e-commerce
Being in the wrong type of entity costs you thousands, maybe tens of thousands of dollars.
S-Corps usually don’t make sense in New York City because of the New York City corporate taxes. So while you get that savings on self-employment taxes on your federal income tax return, you end up getting double-taxed on the city end because you pay city corporate taxes, and then again, city income resident taxes. The net effect: you actually pay more taxes by being an S-Corp than most other structures.
For most NYC e-commerce owners under $100K profit, a single-member LLC is cleaner and cheaper. No separate payroll, no reasonable compensation analysis, no extra return to file.
We had a client who moved from Michigan to New York. Her previous accounting firm forced her into S-Corps she didn’t need. Now that she’s in NYC, we’re moving her to a single-member LLC before year-end so going into 2026 she’s cleanly set up.
Monthly and quarterly bookkeeping
There’s many accountants and accounting firms out there that don’t stress the importance of monthly and quarterly bookkeeping financials. We stress that because we want you to succeed.
Our quarterly cash flow strategy involves keeping your bookkeeping and financials up to date, so we can meet with you on a monthly or quarterly basis. So we don’t cram it into the end of the year and we’re not playing catch up at year end. We force our clients to keep their bookkeeping current so we can actually plan.
Inventory and COGS
For Shopify and Amazon sellers, inventory accounting is where DIY software breaks. Cost of goods sold, landed cost, 263A capitalization, write-downs for unsold inventory. These show up on your return whether you track them or not. If you’re not tracking them, you’re overpaying tax on profit that isn’t really profit.
Small e-commerce sellers under the §448(c) gross receipts threshold (≈$30–31M, inflation-adjusted) are exempt from §263A UNICAP and may expense costs rather than capitalize them into inventory. New York generally conforms to this federal treatment, with no significant state-level deviation.
Quarterly estimated taxes
Any self-employed person or business owner, whether you set up an S-Corp, an LLC, or just a sole proprietor, should pay quarterly payments if you’re profitable. Quarterly payments are due April 15, June 15, September 15, and January 15. No matter what, on those dates we make our e-commerce clients send something in. Even if it isn’t as much as we want them to. It’s better than just doing nothing.

Frequently Asked Questions
Do e-commerce sellers in NYC pay sales tax in all 50 states?
No, only in states where you cross the economic nexus threshold. Post-Wayfair (2018), each state sets its own rule, usually around $100K in sales or 200 transactions per year. Marketplace facilitators (Amazon, eBay, Etsy) collect for you in most states. If you sell direct via Shopify, that obligation falls on you.
How does an NYC Shopify seller pay federal, state, and city tax?
If you’re a single-member LLC or sole prop, your Shopify profit flows through to your personal return. You pay federal income tax + NY state + NYC on that profit. If you’re an S-Corp, the S-Corp return is filed separately, reasonable comp is paid as salary, and the remaining profit still flows through to you. Quarterly estimated payments cover all three stacks.
Do I need a CPA if I use QuickBooks for my online store?
QuickBooks handles the bookkeeping. A CPA handles the strategy: which entity, which state, which deductions, quarterly planning, and the return itself. For a profitable NYC e-comm business with sales in multiple states, QuickBooks alone is not enough.
