Corporate Returns for Ecommerce and Online Sellers in Austin

For most Austin ecommerce sellers who incorporate, the answer is the 1120-S, the S corporation return, and understanding why comes down to how each corporate form is taxed. An S corporation is a pass-through entity, so the corporation itself pays no federal income tax on its profit. Instead the profit flows through to the owner on a Schedule K-1 and is taxed once, on the owner’s personal return. A C corporation, which files Form 1120, is a separate taxpayer that pays the flat 21 percent federal corporate income tax on its profit, and then the owner is taxed again on any dividends distributed, so the same dollars can be taxed twice.

The reason the 1120-S is the usual choice for an online seller is the self-employment tax saving that the structure allows. As an S corporation owner, you pay yourself a reasonable salary that carries payroll tax, and you take the remaining profit as distributions that are not subject to the 15.3 percent self-employment tax. Compared with reporting the entire profit on a Schedule C, where all of it is exposed to self-employment tax, that split can save a profitable seller several thousand dollars a year, which is the main reason a growing store elects S treatment in the first place.

A C corporation still makes sense in specific cases, and it is not simply the wrong answer. A store that reinvests all of its profit back into growth rather than paying the owner, or one that intends to raise outside investment, may benefit from the C corporation’s flat 21 percent rate and its ability to hold earnings inside the company. But for the typical owner-operated Austin store that distributes its profit to the owner, the double tax on a C corporation usually outweighs the flat rate, and the 1120-S is the better fit. The decision turns on how you use the profit, not on a one-size rule.

It is also worth knowing that the election is not permanent in a way that traps you. A store can start as a sole proprietorship, elect S corporation treatment when profit justifies it, and in rare cases revoke that election later if circumstances change, though revocation carries its own timing rules and a five-year wait to re-elect, so it is not a switch to flip casually. The point is that the entity form should track the business as it is now, and we revisit it when your profit or plans change materially rather than locking you into a choice made when the store was small.

Here is the worked example. Your store nets $150,000. As an S corporation you might take a $70,000 salary and $80,000 in distributions, paying payroll tax on the $70,000 while the $80,000 avoids self-employment tax, and the whole $150,000 is taxed once on your personal return, with no Texas income tax on top because Texas has none. As a C corporation the company would pay 21 percent on its profit, roughly $31,500 if none were paid out as salary, and then you would be taxed again on any dividends you took, a heavier combined load for a store meant to pay its owner. Because Texas imposes no state income tax on either entity, the choice is driven purely by the federal math. We model both and prepare the return that fits through entity formation and structuring. The framework is on the IRS S corporations page, with the form detail on About Form 1120-S.

For an Austin ecommerce seller filing an 1120-S corporate return, the reasonable salary is the single most important judgment on the return, because the entire self-employment tax benefit of the S corporation depends on getting it right. The structure works by splitting the owner’s pay into two parts, a salary that carries Social Security and Medicare payroll taxes, and distributions that do not. The IRS requires that the salary be reasonable for the work the owner actually performs, precisely because owners are tempted to set it artificially low to move more profit into the untaxed distribution bucket.

If the salary is set too low, the IRS can step in and recharacterize some or all of the distributions as wages, then assess the payroll tax that should have been paid plus penalties and interest. That reclassification wipes out the saving the low salary was meant to create and can leave you worse off than if you had paid a fair wage from the start. On the other side, setting the salary too high is also a mistake, because every dollar of salary carries the 15.3 percent combined payroll tax, so an inflated salary voluntarily hands back the exact saving the S corporation is supposed to deliver. The target is a defensible middle, not the lowest number you can imagine.

A defensible salary reflects what someone would be paid to do your job, running an ecommerce business of your size and complexity, sourcing product, managing listings and advertising, handling suppliers and fulfillment, and overseeing the finances. The figure should be supported by comparable compensation data for similar roles and documented so it can be explained if questioned. It also has to be consistent across your records, appearing the same on your payroll filings, your W-2, and the wage line of the 1120-S, because a mismatch between the return and the payroll reports is itself a flag.

One nuance sellers miss is that the reasonable salary is not a fixed percentage of profit, even though rules of thumb like a sixty-forty split get repeated online. A store netting $400,000 does not necessarily owe the owner a $240,000 salary, because the value of the labor caps out at what the role is actually worth, and profit beyond that reflects the return on the business and the capital in it, not the owner’s wages. So as profit climbs, the salary rises to a fair market level and then flattens, which means the distribution share grows and the saving widens, but the salary still has to be anchored to the work, not mechanically scaled.

Here is the worked example. Your store nets $150,000 in profit for the year. You and your accountant determine that a reasonable salary for running a store of this size is $70,000, based on what comparable operators earn, so you run $70,000 through payroll and carry it on your W-2 and the 1120-S, paying the combined payroll tax on it. The remaining $80,000 comes to you as distributions, which are not subject to the 15.3 percent self-employment tax, saving roughly $12,000 versus reporting the whole $150,000 on a Schedule C. Because Texas has no state income tax, that saving is not diluted by any state layer. If you had instead set the salary at $20,000 to save more, and the IRS found that unreasonable for the work involved, it could reclassify a large part of the distributions as wages and undo the benefit with penalties added. We set the salary, document its basis, and keep it consistent across the return and payroll through payroll compliance. The IRS standard is in its S corporation compensation guidance.

For an Austin ecommerce seller, cost of goods sold is usually the largest single deduction on the corporate return, so getting it right on the 1120-S or 1120 matters more than almost anything else on the form. The rule inside a corporation is the same as on a personal Schedule C, buying inventory is not an expense at the moment cash leaves the account. That purchase is an asset, product sitting in a warehouse, and it becomes a deduction as cost of goods sold only when the specific units actually sell. Until they sell, the cost stays on the corporate balance sheet as inventory, regardless of how much the company spent acquiring it.

The corporate return computes cost of goods sold with the same formula used everywhere, beginning inventory plus purchases during the year minus ending inventory. The value of unsold product on hand at year end directly reduces the deduction and raises the corporation’s reported profit, so an accurate year-end count and valuation is not optional. In an S corporation, an error here flows straight through to the owner’s K-1 and personal return, and in a C corporation it misstates the profit taxed at the flat 21 percent rate, so either way a wrong number carries all the way to the tax actually paid.

There is a Texas dimension that makes this figure do double duty for an incorporated seller. The Texas franchise tax, which applies to the corporation if its revenue ever crosses the threshold, lets you compute the taxable margin as total revenue minus cost of goods sold, among the allowed methods. So the same clean cost of goods sold number that drives the federal corporate return also feeds the state franchise report, and for an inventory-heavy store the cost of goods sold method often produces the lowest margin, making an accurate figure valuable on both returns at once.

What counts inside cost of goods sold is broader than the sticker price of the product, and getting the components right is part of the job. For a store that imports, the landed cost includes the purchase price plus freight, customs duties, and inbound shipping, all of which belong in inventory value rather than in a separate expense line. Pulling those costs out and expensing them immediately, a common error, understates inventory and overstates the current deduction, which distorts both the federal return and the franchise margin. So the schedule has to capture the full cost of getting each unit onto the shelf, not just what the supplier invoiced for the goods themselves.

Here is the worked example. Your incorporated store begins the year with $80,000 of inventory, purchases $300,000 of product during the year, and ends with $90,000 still on the shelf. Cost of goods sold is $80,000 plus $300,000 minus $90,000, which equals $290,000. That figure appears on the corporate return as the deduction against your sales, and if the store’s revenue is high enough to owe franchise tax, the same $290,000 reduces the taxable margin on the Texas report. A corporation that instead expensed the full $300,000 of purchases and ignored the $90,000 still on hand would understate its profit by $90,000, misstating both the federal return and any franchise filing, with the correction bringing tax, and possibly penalties, later. We build the cost of goods sold schedule and reconcile inventory as part of monthly financial reporting so the corporate return and the franchise report both rest on the same real number. The inventory rules are in IRS Publication 538, and the franchise margin rules are with the Texas Comptroller.

For an Austin ecommerce seller, the corporation does not owe a Texas income tax, because Texas has no corporate or personal income tax, but it very likely has a Texas franchise report to file alongside the federal corporate return, and the difference between those two things trips people up. There is no state version of the 1120-S or 1120 to file in Texas, which is a genuine saving compared with a state like California that taxes the entity and does not fully conform to the federal treatment. What the corporation does step into by existing is the Texas franchise tax system, which applies to LLCs and corporations regardless of the absence of an income tax.

The franchise tax is an entity-level tax measured on taxable margin, not on your take-home profit, and the feature that spares most incorporated sellers is the no-tax-due threshold. An entity with annualized total revenue at or below roughly $2.65 million owes no franchise tax for the year, so the majority of small and midsize online stores owe nothing. The problem sellers run into is not the tax, it is the filing, because depending on revenue and the year’s rules an LLC or corporation may still have to file a franchise report and a Public Information Report every year even when the tax due is zero.

That filing matters more than a zero-dollar liability makes it sound, because failing to file can cause the state to forfeit the corporation’s right to transact business in Texas. A forfeiture can jeopardize the liability protection that was the whole reason to incorporate, and it can complicate contracts, financing, and even the ability to bring a lawsuit, so an incorporated seller who skips the franchise report because no tax is due can create a real problem out of what looked like a non-event. This is why we file the franchise report as a matter of course whenever we prepare a corporate return for an entity, rather than treating it as optional.

The franchise report also has its own due date, generally May 15 each year, which is separate from the federal corporate return deadline, so an incorporated seller is really tracking two filing calendars rather than one. Missing the May date does not wait quietly, because the Comptroller sends notices and can move toward forfeiture if the report stays unfiled, and reinstating a forfeited entity takes a separate filing and sometimes a fee. Keeping both dates on one schedule is a small piece of housekeeping that prevents a large headache, and it is part of what we manage so the state and federal obligations do not drift apart.

Here is the worked example. Your store operates as an S corporation with $1.9 million in total revenue. Because that is below the roughly $2.65 million threshold, the corporation owes no franchise tax, but it still files the franchise report and the Public Information Report to stay in good standing, which we handle with the federal 1120-S. Now suppose revenue grows to $3.2 million with $1.7 million of cost of goods sold. The corporation now exceeds the threshold, so franchise tax applies, and computing the margin as revenue minus cost of goods sold gives a $1.5 million margin taxed at the applicable low rate, a few thousand dollars, far below an income tax on the profit in most states, and still with no Texas tax on the owner personally. We file the corporate return and the franchise report together through tax compliance so neither is missed. The rules are with the Texas Comptroller, and the federal S corporation framework is on the IRS S corporations page.

For an Austin ecommerce seller, the move from a Schedule C to a corporate return, almost always an 1120-S, is driven by profit reaching a level where the self-employment tax saving outweighs the added cost and complexity of running a corporation. While your store is small, reporting it on Schedule C attached to your personal 1040 is simple and cheap, with no separate return, no payroll, and no corporate filings. The catch is that every dollar of that Schedule C profit is exposed to the 15.3 percent self-employment tax, and as profit grows that tax becomes the largest avoidable cost in the business.

The S corporation changes the math by letting you split your pay. You take a reasonable salary that carries payroll tax and receive the rest of the profit as distributions free of self-employment tax, so the saving grows as the distribution portion grows. That saving has to clear the new costs the corporation brings, running payroll for your salary, filing a separate 1120-S return, and in Texas filing the franchise report, plus the general overhead of maintaining the entity. Below a certain profit level those costs eat up the saving, and above it the saving pulls clearly ahead, which is why the timing is a calculation rather than a milestone you cross by feel.

A rough rule many sellers use is that the S election starts to pay off somewhere around $40,000 to $50,000 of net profit beyond a reasonable salary, but the honest answer is that it depends on your specific numbers, because the reasonable salary for your work, the exact profit, and the cost of running payroll all move the break-even. In Texas the decision is a little cleaner than elsewhere, because there is no state income tax whose treatment of S corporations you also have to weigh, so the analysis is essentially federal, with the franchise report as a filing cost rather than a tax.

Timing within the year also matters, because the S election generally has to be filed within roughly the first two and a half months of the tax year to take effect for that whole year, or it applies to the following year instead. So a seller who realizes in October that the store has grown into S corporation territory usually elects for the next year and runs the current year on Schedule C, rather than getting partial-year treatment. Planning the switch a little ahead, rather than at filing time, is what captures the saving in the earliest year possible, and it is a common reason to look at the numbers mid-year rather than waiting for the spring return.

Here is the worked example. Your store nets $60,000. A reasonable salary might be $45,000, leaving $15,000 as distributions, and the self-employment tax saved on that $15,000 is about $2,300, which barely covers the cost of payroll and a second return, so staying on Schedule C is defensible. Now the store grows and nets $150,000. A $70,000 reasonable salary leaves $80,000 in distributions, and the self-employment tax saved on that $80,000 is roughly $12,000, comfortably ahead of the few thousand dollars the corporation costs to run, so the S election clearly pays. We run this break-even on your actual numbers and handle the election and setup at the right time through entity formation and structuring. The S corporation framework is on the IRS S corporations page, and the Texas franchise obligation is with the Texas Comptroller.
