S Corporation tax benefits

Starting a business with the goal of “taking it public” or attracting institutional investors is the goal of many entrepreneurs.

Bootstrapping a business and trying to grow it as large as possible, with the goal of either staying on as the founder/CEO or eventually selling to another business, is another common goal of entrepreneurs.

A third objective for starting a business is aiming to sustain a particular level of income with as few employees as possible. These entrepreneurs don’t have the ambition to grow as big as possible and eventually sell. Their goal is to build a business to a specific income level that can sustain the founder’s preferred lifestyle. This is where the term “lifestyle business” comes from.

For many of these so-called lifestyle businesses, the S corporation entity is a perfect choice for a business entity. You may already be asking yourself how are S corporations both similar and different to C corporations? What makes an S corporation a good fit for a lifestyle business?

Where does an S corporation come from?

Both C corporations and S corporations are born the same way – by filing Articles of Incorporation with the state in which the business will be located. (A business organized as a limited liability company can also elect to be treated as an S corporation for tax purposes.)

Once a business has incorporated, it can choose to be taxed either as a C corporation or S corporation.

If the business wants to be taxed as a C corporation, nothing further needs to be done. The default tax entity for an incorporated business is the C corporation.

If the business wants to be taxed as an S corporation, Form 2553 (“Election by a Small Business Corporation”) needs to be filled out and submitted to the IRS. Filling out Form 2553 and submitting it to the IRS is also referred to as “making an S-election.”

As with any other IRS form, there is a deadline to submit Form 2553. The general deadline to submit an S-election is the due date for the S corporation’s tax return. For an S corporation with a December 31 year-end, the deadline to submit both the tax return and S-election is March 15^th.

A simple structure for simple businesses

If you wanted to start a business in the first half of the 20^th century, you had two options:

Form a C corporation to take advantage of liability protection but be subjected to two layers of federal tax at the corporate and individual level, or…
Choose to be a sole proprietorship or partnership, enjoy the benefit of a single layer of taxation, but forgo the liability protection afforded C corporations.

Neither of these choices was favorable for small and family-owned businesses. In 1946, the Department of Treasury suggested the third choice of entity, one that combined the liability protection of a C corporation with the single layer of taxation from sole proprietorships or partnerships.

U.S. taxpayers waited another 12 years before this suggestion of a hybrid entity actually came to fruition. In 1958, Congress and President Dwight Eisenhower created Subchapter S of the tax code. Subchapter S provided the benefit of limited liability that C corporations have while maintaining the tax benefits of sole proprietorships and partnerships.

The S corporation was created to address the specific problems faced by small businesses looking to enter markets dominated and controlled by large corporations.

There were four trade-offs, however, to using the new S corporation entity structure:

Must be a domestic business
Have a limitation on the number of shareholders it is allowed to have
Have limitations on who could be a shareholder
Can only have one class of stock

For many small businesses in the mid-20^th century, these limitations were often never an issue.

Former Internal Revenue Service commissioner Don Alexander described the S corporation as “a simple structure for simple people” and simple businesses during Congressional testimony in 2006.

Let’s take a closer look at each one of these limitations and how they affect businesses 60 years after the S corporation was written into law.

S corporations: Must be a domestic business

When grappling with how to best help small businesses in the United States, the Internal Revenue Service, Congress, and President Eisenhower recognized the need for a business entity that combined the limited liability of a C corporation and the simplicity of a sole proprietorship or partnership.

Our esteemed politicians also understood that a new, hybrid business entity could lead to all kinds of unintended consequences. (That’s how the U.S. tax code works, right? Congress passes a law, then CPAs and attorneys figure out different ways of legally working around the new law.)

To make sure that this new, hybrid entity would benefit only U.S. small businesses, the first limitation of an S corporation is that it must be a domestic business.

S corporations: Limitation on number of shareholders

When S corporations were first created in 1958, the maximum number of shareholders allowed was 10. The number of allowable shareholders slowly increased every few years. The American Jobs Creation Act of 2004 expanded the allowable number of shareholders to its current level of 100.

One of the reasons the number of allowable shareholders kept increasing was to accommodate family businesses that grew over multiple generations to include multiple family members. This problem was also addressed in 2004 when new rules allowed all members of a family (as defined by the tax code) to be treated as a single shareholder.

S corporations: Limitations on who can be a shareholder

Shareholders of an S corporation must be U.S. citizens or residents; non-resident aliens are not permitted to be a shareholder.

Shareholders must also be natural people; therefore corporations and partnerships are ineligible to be shareholders.

Certain trusts, estates, and tax-exempt corporations (including 501(c)(3) corporations) are eligible to be S corporation shareholders.

An S corporation can also be a shareholder in another subsidiary S corporation if the parent S corporation owns 100% of the stock of the subsidiary corporation. An election is made to treat the subsidiary S corporation as a “qualified subchapter S subsidiary.” Once the election is made, the subsidiary S corporation is not treated as a separate organization for tax purposes.

There have been ongoing discussions about this particular limitation and if changes should be made due to the global nature of today’s economy. When the S corporation was born in 1958, opportunities to be a nonresident alien shareholder were not that common, for example. But in today’s global economy, many businesses have employees as well as owners and investors located in multiple foreign jurisdictions.

While the limitation on who can be an S corporation shareholder will likely never completely go away, stay tuned to see what changes might be made in the future to accommodate the everchanging way that countries around the world conduct business.

S corporations: Can only have one class of stock

The Internal Revenue Service’s definition of a single class of stock means that all shares of stock outstanding must provide “identical rights to distribution and liquidation proceeds.”

Another way to interpret this definition is all profits and losses are allocated to shareholders proportionately to each shareholder’s interest in the corporation.

The effect of these limitations affect S corporations

These four limitations don’t affect 90% of S corporation businesses

So with these four stipulations on what an S corporation is allowed and not allowed to do, wouldn’t it be a headache to be an S corporation shareholder?

For sure, some businesses would have trouble avoiding these four limitations. But for the vast majority of businesses who elect to be taxed as an S corporation, these limitations rarely get in the way. And the statistics of S corporations back up this theory.

In 1995, there were 2,153,119 S corporation tax returns filed with the Internal Revenue Service. In 2003, the number of S corporations was approaching 3.5 million, an increase of 65% percent.

C corporation tax returns, on the other hand, decreased from 2.6 million in 1986 to 2 million in 2003.

Despite the extra hurdles S corporation shareholders need to jump through, the S corporation was a smashing hit with U.S. small business owners.

Here’s another statistic to consider – Close to 90% of S corporations have 3 or fewer shareholders: In 1995, 52% of S corporations had 1 shareholder; 30% had 2 shareholders; 7.6% had 3; 8.7% had 4 to 10. Only 1.6% of all S corporations had more than 10 shareholders. Average total assets for S corporations were $473,000, while C corporations averaged $10.8 million.

The vast majority of S corporations are truly small businesses run by a small number of shareholders. These businesses never encounter the 100 shareholder limit, have to deal with ineligible shareholders or multiple classes of stock. The S corporation is serving exactly who it was intended to serve: small businesses based in the United States.

Losing S corporation status

The S corporation is the only business entity where you can lose your entity tax status.

And it’s pretty simple to do it.

All a business has to do to lose its S corporation status is violate one of the four restrictions mentioned earlier in this article:

Have more than 100 shareholders;
Having the business be a foreign business;
Have an ineligible person or entity as a shareholder; and
Have more than one class of stock.

Shareholders must be vigilant in a business’s compliance with these limitations because these limitations can sometimes be inadvertently violated.

Ownership limitations make raising capital difficult

If you’re starting a business with the goal of raising capital or attracting investors at some point in the future, electing to be an S corporation could possibly hinder these efforts.

What happens if you have an angel investor from England who wants to provide your business with several hundred thousand dollars? What about a venture capital firm headquartered in Singapore wanting to invest in your business? You would have to turn down both these potential investors because the angel investor is a foreign alien, while the venture capital firm is a partnership. Both foreign aliens and partnerships are ineligible to be S corporation shareholders.

If you are fortunate enough to find angel investors who live in the U.S., many companies will require a number of different investors. The 100 shareholder limitation can fill up pretty quickly.

S corporations are a great option for lifestyle businesses

President Dwight Eisenhower and Congress were successful in creating a hybrid entity that helped small business owners in the U.S.

With most featuring three or fewer shareholders, very few S corporations have to worry about the hurdles surrounding who can be a shareholder, the number of shareholders, being based in the U.S., and having only one class of stock.

That’s why the S corporation is a perfect fit for these lifestyle businesses whose owner has no grand ambition to grow the business as large as possible and attract as many investors as possible.

S corporation tax filing

An S corporation files its tax return on Form 1120-S. Each shareholder receives a Form K-1 from the S corporation. K-1s report each shareholder’s allocation of income, losses, and other financial information from the business. The shareholder includes Form K-1 information on their individual tax return.

This section discusses filing an S corporation tax return and the associated Form K-1s. If you have an S corporation, please contact our office with any questions about how to file a Form 1120-S or how to include a Form K-1 on your individual tax return.

Keep your accounting records and financial statements up-to-date. An accurate balance sheet and income statement helps to make preparing your S corporation tax return extremely easy every year and will ensure that you don’t run the risk of reporting too much (or too little) income. If your business grows big enough, you’ll be required to report your balance sheet on Schedule L of your S corporation’s tax return.
Record your income. The first section of Form 1120-S is where your business’s income and cost of goods sold are recorded.
Record your expenses. The second section of Form 1120-S is where your business’s expenses are recorded.
Calculate your net profit or loss. Subtract your total expenses from your gross income to compute your net profit or loss. On an S corporation tax return, the technical name for your business’s profit or loss is “ordinary income or loss”.
Record taxes owed and payments made. The vast majority of S corporations do not owe taxes at the business entity level. As discussed before, shareholders normally pay taxes on their share of the business’s profits on their individual tax returns. There are several limited circumstances where an S corporation would owe taxes at the entity level. This is the section where these tax liabilities would be recorded.
Answer questions on Schedule B. Stretching over all of Page 2 and on to Page 3 of Form 1120-S, Schedule B can be thought of as a questionnaire that encompasses various areas of your business. The questions range from asking about the business’s stock structure to ownership interest by shareholders.
Complete Schedule K. This schedule is what will be used to allocate dollar amounts and other information from Form 1120-S to the shareholders.
Complete Schedule L. If required, complete Schedule L. This is where you would report your business’s balance sheet.
Complete Schedule M-1. This schedule is where you reconcile taxable vs. non-taxable income and deductible vs. non-deductible expenses.
Complete Schedule M-2. This schedule is a more detailed look at the shareholders’ capital accounts.

Information from your Form K-1

The K-1 you receive from your S corporation will contain the following information to report on your individual income tax return: Ordinary business income or loss; Rental income or loss; Interest income; Dividend income; Royalties; Capital gains or losses; Other income or losses; Section 179 Expense; Deductions that don’t get rolled up into the business’s overall profit or loss for tax purposes; Tax credits; Items that affect alternative minimum taxable income; Items that affect shareholder basis.

This is just a quick overview of Form 1120-S and Form K-1. Please call our office if you have any questions about filing a tax return for your S corporation or how to report K-1 information on your individual tax return.

Does an S corporation shareholder need to pay quarterly taxes?

An S corporation shareholder is generally required to make estimated tax payments, as taxes must be paid as you earn or receive income throughout the year, either through withholding or estimated tax payments. Estimated tax payments are used to pay not only income tax but also other taxes such as self-employment tax and alternative minimum tax.

Deadline to pay your estimated taxes

For estimated tax purposes, your tax year is divided into four payments periods:

1^st Payment Deadline – April 15^th – Covers income earned from January 1 to March 31
2^nd Payment Deadline – June 15^th – Covers income earned from April 1 to May 31
3^rd Payment Deadline – September 15^th – Covers income earned from June 1 to August 31
4^th Payment Deadline – January 15^th – Covers income earned from September 1 to December 31

NOTE: If the payment deadline falls on a weekend or legal holiday (i.e. Martin Luther King, Jr. Day in January and Washington D.C.’s Emancipation Day in April), you may wait until the following business day to mail or submit your payment.

How to calculate your estimated taxes

Here are some suggestions for figuring out how much your estimated tax should be:

A good starting point is to use your prior year Form K-1 received from your S corporation.
Next, estimate your expected adjusted gross income, taxable income, taxes, deductions, and credit for the entire tax year.
Use the worksheet provided by the IRS in the instructions to Form 1040-ES or call our office for assistance.

If you subsequently discover that your estimate was too high, simply complete another Form 1040-ES worksheet to recalculate your estimated tax when it comes time for your next payment. If your estimate was too low, complete another Form 1040-ES worksheet to adjust your next payment.

How to pay your estimated taxes

You can send estimated tax payments with Form 1040-ES by mail, or you can pay online, by phone, or from your mobile device using the IRS2Go app. You can pay your estimated taxes weekly, bi-weekly, monthly, etc. as long as you’ve paid enough in by the end of the quarter.

Avoid paying a penalty!

If you don’t pay enough tax through withholding and estimated tax payments, you may be charged a penalty and/or interest. You may also be charged with a penalty if your estimated tax payments are late, even if you are due a refund when you file your tax return.
