When you’re building an eCommerce brand, your thoughts typically focus on marketing funnels, customer acquisition costs, and the next product launch. Taxes are often the last thing you want to think about.
But the most successful e-commerce founders have understood something important: tax strategy is not a one-time scramble in April. It’s part of running the business all year round. The goal is not only to increase sales but also to protect profits. After all, it’s not about what you do; It depends on what you keep.
As a CPA who works extensively with online sellers, I’ve seen both ends of the spectrum: business owners who used smart tax planning to save enough for a dream home and others who were surprised by six-figure IRS bills they couldn’t pay. If you want to keep more of your profits in your pocket, here are five IRS-focused strategies every ecommerce founder should understand.
Sales tax: The silent growth killer
Many founders assume that they only have to collect sales tax in their home state. That may have been the case years ago, but not anymore.
For example, if you store inventory in an Amazon FBA warehouse in Texas, you likely have “nexus” there and must comply with Texas sales tax regulations. I once worked with a client who did over $100,000 in sales in New York without realizing they had triggered an economic nexus. He ended up with three years of back taxes and penalty notices – a costly mess to sort out.
To avoid this, you should understand where your business has a tax footprint, whether through physical presence (e.g. inventory) or economic thresholds. Register before you start collecting sales tax, keep an eye on registration deadlines, and don’t rely solely on software automation. Sales tax compliance continues to require active oversight.
Tax deadlines aren’t just April 15th
This surprises new business owners every year. While your personal tax return is typically April 15, your business return may be due weeks earlier.
Every spring I get calls from LLC owners who receive penalty notices for filings they didn’t even know existed.
The solution is simple: Work with your CPA to create a calendar of all filing deadlines, including quarterly estimated tax payments. If you expect to owe more than $1,000 in taxes for the year, the IRS generally requires you to pay throughout the year, rather than all at once in April. Missing these payments can result in unnecessary penalties and interest.
Your company structure is more important than you think
Your business structure is your tax plan.
Many entrepreneurs start out as sole proprietors or sole proprietorships because it is easy to set up. But simplicity can come at a price: You may have to pay the full 15.3% self-employment tax on all net profits.
One Shopify seller we worked with made about $80,000 in annual profits as a sole proprietor. By choosing S corporation status, she paid herself a reasonable salary of $50,000, subject to payroll taxes, while the remaining $30,000 came through without additional self-employment taxes. This one change saved her more than $4,500 in the first year alone.
For higher-earning companies, the savings can be significantly greater.
On the other hand, many e-commerce founders default to forming Delaware C-corporations because they have heard that this is “the best” setup. This may make sense for startups seeking venture capital, but for many profitable, privately held brands, a C corporation can result in double taxation – once at the corporate level and again when profits are distributed as dividends. In many cases, an S corporation is the more tax efficient option in your home state.
Beware of the 1099-K trap
Platforms like Shopify Payments, PayPal, and Stripe now report your gross sales directly to the IRS via Form 1099-K.
The IRS uses automated systems to compare these numbers to the income reported on your tax return – and discrepancies can quickly lead to alerts.
One client, an excellent marketer but disorganized accountant, received a notice after his return showed $400,000 in sales while his 1099-Ks showed $500,000. The difference resulted from poor recordkeeping of refunds and processing fees, but the IRS assumed the missing $100,000 was unreported income.
We ultimately solved the problem, but only after a stressful and expensive reconstruction of his books.
The Takeaway: Reconcile your accounting records with your 1099-Ks regularly and ensure payment processor fees are properly recorded as deductible business expenses.
Your biggest tax opportunities come before the end of the year
The fourth quarter is often your last opportunity to reduce your tax bill through strategic planning.
It was predicted that a customer would end the year with a profit of $120,000. Before the end of the year, we helped him prepay $15,000 in marketing expenses for upcoming campaigns, purchase $8,000 in equipment that could be immediately depreciated, and maximize SEP-IRA contributions with an additional $25,000.
These decisions reduced his taxable income by nearly $50,000 and saved him more than $15,000 in taxes – capital that he could reinvest directly into the business.
The most successful founders treat tax planning the same way they treat marketing or operations: as an ongoing strategic function of the company. Clean books, proactive planning and the right advisory team can mean the difference between scaling safely and being surprised by avoidable tax issues.
Don’t wait for an IRS notice to be your wake-up call.
