Do S Corps Pay Quarterly Taxes?

When starting a small business, one of the many decisions you’ll face is how to structure it. An increasingly popular choice is the S corporation (S corp), especially for its potential tax benefits. However, a common question many business owners ask is: Do S corps pay quarterly taxes?

The short answer is yes, S corps do pay quarterly taxes, but the process can be a bit more nuanced. In this article, we'll explore how S corps are taxed, who pays these taxes, and why quarterly payments are necessary.

What Is an S Corporation?

An S corporation is a special tax designation that allows small businesses to avoid the double taxation that applies to traditional C corporations. In a C corp, income is taxed twice—once at the corporate level and again when dividends are distributed to shareholders. However, an S corp is a pass-through entity, meaning that the corporation itself is not taxed. Instead, profits and losses are passed through to the shareholders, who report them on their personal tax returns.

To qualify as an S corp, your business must meet certain IRS requirements, such as having no more than 100 shareholders, issuing only one class of stock, and being a domestic company.

How Are S Corps Taxed?

S corporations do not pay corporate income tax. Instead, profits, losses, deductions, and credits are passed through to shareholders, who report them on their personal tax returns. This structure allows S corps to avoid the double taxation faced by C corporations.

The taxation process for an S corp primarily involves two levels:

1. Shareholder Taxes

Shareholders in an S corp are responsible for paying taxes on their share of the company’s income. Each shareholder receives a Schedule K-1 form, which details their portion of the business's income, deductions, and credits. The shareholder must then report this information on their personal tax return.

For example, if a shareholder owns 50% of an S corp and the company earns $100,000 in profit, the shareholder must report $50,000 of that income on their personal tax return. This income is subject to individual income tax rates, and the shareholder may also be required to pay self-employment taxes on any wages they receive from the company.

2. Payroll Taxes

Although S corps pass through profits to shareholders, they still need to handle payroll taxes for any employee wages paid, including wages to shareholder-employees. Shareholders who actively work in the business must be paid a reasonable salary. The company is responsible for withholding and remitting payroll taxes on these wages, including Social Security and Medicare taxes.

Failure to pay a reasonable salary or appropriately withhold taxes can result in fines and penalties from the IRS.

What Are Quarterly Taxes?

For S corps, shareholders typically need to make quarterly estimated tax payments. But what are quarterly taxes?

Quarterly taxes refer to the system the IRS uses to collect taxes from self-employed individuals and business owners, including shareholders in S corps. Since taxes are not withheld from pass-through income the way they are from employee wages, shareholders are required to pay estimated taxes four times a year.

The due dates for quarterly taxes are:

  1. April 15

  2. June 15

  3. September 15

  4. January 15 (of the following year)

These payments cover both federal and state income taxes, as well as self-employment taxes where applicable.

Why Do S Corp Shareholders Pay Quarterly Taxes?

S corp shareholders pay quarterly taxes to ensure they meet their tax obligations throughout the year, rather than waiting until the annual tax filing deadline. The IRS expects individuals to pay taxes as they earn income. Since S corps don’t withhold taxes from pass-through income, shareholders need to make estimated payments directly.

If you fail to make these payments or underpay your estimated taxes, you may face penalties and interest charges when you file your annual tax return. The IRS imposes underpayment penalties when individuals or businesses owe too much in taxes at the end of the year.

To avoid these penalties, shareholders should calculate their estimated tax liability and pay it quarterly. These payments should cover your federal and state taxes, and in some cases, self-employment taxes if you also receive wages from the S corp.

How to Calculate Quarterly Taxes for S Corps

Calculating quarterly taxes for S corp shareholders involves estimating your tax liability for the year and dividing that amount into four equal payments. This can be tricky, especially if your income fluctuates throughout the year. Here’s a basic process to follow:

  1. Estimate your total income for the year: This includes your share of the S corp’s profits, any wages you earn as an employee of the S corp, and any other personal income.

  2. Subtract deductions and credits: These could include business expenses, retirement contributions, and other tax deductions. You may also qualify for certain tax credits, such as the Earned Income Tax Credit (EITC) or the Child Tax Credit.

  3. Calculate your taxable income: After accounting for deductions and credits, you’ll have your taxable income.

  4. Apply your tax rate: Using the IRS tax tables, calculate your estimated federal income tax liability for the year. Be sure to also account for state income taxes if applicable.

  5. Divide into four payments: Once you know your total estimated tax liability, divide that amount by four. These will be your quarterly payments.

You can use IRS Form 1040-ES to help calculate your estimated tax payments.

Employer Tax Responsibilities for S Corps

In addition to the shareholders’ obligation to pay quarterly taxes, the S corp itself has certain responsibilities. As mentioned earlier, S corps must pay payroll taxes on any wages paid to employees, including shareholders. These taxes include:

  • Social Security taxes

  • Medicare taxes

  • Federal unemployment taxes (FUTA)

  • State unemployment taxes (SUTA)

S corps must also deposit these payroll taxes on a regular schedule, which could be semi-weekly or monthly depending on the amount of payroll. Additionally, they need to file quarterly and annual payroll tax returns using forms such as Form 941 (Employer’s Quarterly Federal Tax Return) and Form 940 (Employer’s Annual Federal Unemployment Tax Return).

State Tax Obligations for S Corps

In addition to federal taxes, S corps may also be subject to state tax obligations. Some states impose their own income taxes on S corps, or they may require the business to file an information return. State rules can vary widely, so it’s essential to consult with a tax professional or check your state’s guidelines to ensure compliance.

Certain states also require S corps to pay franchise taxes or other fees. For example, California imposes a minimum franchise tax of $800 on S corporations, regardless of profitability.

Conclusion

Yes, Do S corps pay quarterly taxes, but it’s important to understand that the responsibility largely falls on the shareholders. S corp owners must pay taxes on their share of the business’s profits, and they’re required to make quarterly estimated tax payments to the IRS to avoid penalties.

Running an S corp offers the benefit of avoiding double taxation, but it comes with its own set of obligations, such as payroll taxes and meeting state tax requirements. For business owners and shareholders, staying on top of quarterly tax payments is essential for maintaining compliance and avoiding hefty penalties.
