Specialized accounting, tax planning, and compliance services for New Jersey online sellers, Amazon FBA businesses, and high-growth e-commerce brands. We handle the complexity of NJ’s tax environment — so you can focus on scaling your business.
The Online Seller CPA is a boutique accounting firm built exclusively for the e-commerce industry. We do not serve general business clients or traditional retail — every client we work with is an online seller, and every member of our team has deep expertise in the platforms, payment processors, marketplace economics, and tax rules that define modern e-commerce.
New Jersey is one of the most active e-commerce states in the Northeast. Its dense population, proximity to major Amazon fulfillment centers, and position in the New York metropolitan market make it a hub for online sellers — and one of the more demanding tax environments in the country. New Jersey imposes its own state income tax, corporate business tax, sales tax, and has specific rules around digital goods that many other states have not yet addressed.
Whether you are a solo Amazon FBA seller building your first private label brand or a multi-channel DTC company processing millions across Amazon, Shopify, and Walmart, our team delivers the same standard of precise, proactive, and professional financial service.
Meet Our Team →Our full suite of accounting, tax, and advisory services is purpose-built for the demands of New Jersey online sellers and Amazon FBA businesses.
Year-round federal and New Jersey state tax planning for NJ online sellers. We optimize entity structure, manage quarterly estimated tax payments to both the IRS and NJ Division of Taxation, and identify every legal deduction available — from COGS and software to home office and fulfillment costs.
Specialized bookkeeping and financial reporting for Amazon FBA and FBM sellers in New Jersey. We reconcile Amazon settlement reports, track FBA fees and reimbursements, manage inventory valuation, and produce accurate profit-and-loss statements that reflect true seller economics.
Complete management of New Jersey sales tax obligations. This includes nexus analysis, NJ Division of Taxation registration, ST-50 return preparation and filing, economic nexus monitoring, digital goods taxability analysis, and audit defense support when needed.
Clean, accurate, and timely monthly bookkeeping aligned with your e-commerce platforms and payment processors. We categorize every transaction, reconcile all channels, and deliver financial statements that give you a true picture of revenue, expenses, and cash flow.
Amazon FBA sellers with inventory in New Jersey’s fulfillment centers — or other warehouses nationwide — may have nexus obligations across multiple states. We manage registration, filing, and compliance in every required jurisdiction, including voluntary disclosure for historical exposure.
Beyond compliance, your CPA serves as a financial partner. We provide cash flow forecasting, pricing and margin analysis, inventory cost optimization, entity structuring guidance, and expansion planning — helping New Jersey e-commerce sellers make confident, data-driven decisions at every stage of growth.
Amazon FBA and FBM selling introduces a distinct set of financial, tax, and accounting challenges that general CPA firms are ill-equipped to handle. Settlement report reconciliation, FBA fee tracking, multi-state nexus from warehouse inventory, and COGS calculations specific to Amazon’s fulfillment model all require a genuine specialist — not an accountant trying to learn as they go.
New Jersey is home to several major Amazon fulfillment centers, meaning NJ-based sellers — and sellers elsewhere whose inventory flows through NJ warehouses — frequently have New Jersey sales tax nexus. Our team monitors FBA inventory placement and proactively manages the resulting compliance obligations before they become a problem.
The Online Seller CPA has worked with Amazon sellers at every revenue tier — from early-stage FBA sellers building their first private label product to seven-figure brand owners managing hundreds of ASINs across multiple Amazon marketplaces globally. Our Amazon seller accounting practice is built around what actually matters: accurate profitability by ASIN, clean books ready for investors or lenders, and a tax strategy that keeps more of your Amazon revenue in your business.

Accurate tracking of landed costs, inbound shipping, prep fees, storage, and fulfillment charges to calculate true Cost of Goods Sold and per-unit profitability for every ASIN.

New Jersey consistently ranks among the highest-tax states in the nation, and its approach to e-commerce taxation reflects that complexity. For online sellers, the state presents three primary obligations: the New Jersey Gross Income Tax (GIT) for individuals and pass-through entities, the New Jersey Corporation Business Tax (CBT) for C-corporations and some LLCs, and New Jersey sales and use tax administered by the Division of Taxation.
New Jersey’s sales tax rate is 6.625%, with a reduced rate of 3.3125% for certain qualifying items. One of New Jersey’s most important distinctions for e-commerce sellers is its treatment of digital goods and Software-as-a-Service (SaaS). New Jersey broadly taxes digital products — making it one of the more aggressive states in this area. Sellers of digital downloads, software licenses, and streaming content into New Jersey must collect and remit sales tax on those transactions.
New Jersey’s economic nexus threshold — $100,000 in annual sales or 200 transactions — is lower than California’s, meaning even moderate-volume sellers may trigger NJ obligations. Combined with FBA fulfillment center presence in the state, many online sellers find themselves with unrecognized NJ tax exposure. Working with a dedicated e-commerce CPA in New Jersey ensures these obligations are identified and managed before they escalate into penalties or audit risk.
New Jersey taxes digital products broadly. E-commerce sellers offering software, downloads, or SaaS into NJ may have unrecognized sales tax obligations on those revenue streams.
At $100,000 or 200 transactions, NJ’s nexus threshold is one of the lower thresholds nationally. Moderate-volume sellers often reach this without realizing it.
Amazon operates major fulfillment centers in New Jersey. Sellers whose inventory is stored in these facilities have physical nexus in NJ regardless of their home state or revenue level.
