What Are Quarterly Taxes?

Quarterly taxes are also called estimated taxes. These taxes are the payments made by businesses or individuals every quarter for federal withholding to the IRS. For the current year, if you owe $1000 or more in taxes, then you need to pay quarterly taxes.

Quarterly taxes include self-employment tax, federal income tax, and other applicable taxes. For instance, the Medicare and Social Security taxes. To help you calculate your quarterly tax payments, the IRS provides Form 1040. Knowing about your estimated tax payments, you can fulfill your tax obligations and avoid any penalties.

Furthermore, these taxes are also known as quarterly estimated taxes, estimated federal income taxes, quarterlies, or self-employment taxes.

This was all about quarterly taxes. Moving ahead, let's know the benefits of paying these taxes. 

Benefits of Paying Quarterly Taxes

Paying quarterly taxes comes with several benefits that help in managing your finances simply. To get you an idea, here are some perks of paying these taxes.

  • Quarterly taxes help in avoiding interest and penalties that are charged if you fail to pay taxes on time.
  • Paying quarterly taxes helps you fulfill your tax obligations. In addition, at the end of the year, reduce your tax liability.
  • Another significant benefit of paying quarterly taxes is that it improves your cash flow.
  • Through regular quarterly payments, at the end of the year, you avoid the financial strain of paying a large tax bill.
  • Additionally, paying quarterly taxes also helps you to stay organized. Further, better control your financial condition.

These are some of the benefits of paying quarterly taxes. Moving further, let's discuss who files these taxes.

Who Files Quarterly Taxes?

As mentioned above, if you have a small business or work as self-employed, then you need to pay quarterly taxes. Further, if you work as any of these, then you are generally considered self-employed:

  • Sole proprietor
  • Independent contractor
  • Individuals who run a business on their own, including part-time work
  • Member of a partnership, such as an LLC, that gets guaranteed payments.

These are the people who need to file quarterly taxes. Moving forward, let's know who should pay estimated taxes.

Who Should Pay Estimated Taxes?

To collect the quarterly taxes, the IRS uses a pay-as-you-go income tax system. This means that on your earned income, you should pay taxes. The IRS enforces the estimated tax by charging penalties or fees for underpayment. If you do not pay income taxes through withholding or make quarterly payments, you face penalties. Additionally, on late payments of taxes, penalties are also charged even if you qualify for a refund. 

To know whether you qualify for the estimated tax payments or not, a couple of rules are used by the IRS. These are as follows:

  • After subtracting tax credits and withholding when filing your tax return, you owe $1000 or more in taxes.
  • You expect your tax credits and withholding to be less than:
    • 100% of the tax liability of the previous year, assuming that all 12 months of the calendar year are covered.
    • 90% of your calculated tax liability for the present tax year.

These are known as safe harbor rules. Further, if your adjusted total income is more than $150000 ($75000, if you are married and file separately), the 100% requirement went to 110%.

For individuals who earn a minimum of two-thirds income from fishing or farming, one tax exception applies to them. The requirement is to pay 100% tax on the last year or pay two-thirds of the current year tax. Additionally, there is only one estimated date of paying tax, i.e., January 15 of the following year. Further, if you make a complete payment on March 1, then you do not need to pay estimated tax payments.

Moreover, quarterly paying taxes helps in avoiding a cash crunch that you may face during your tax return. Also, it makes the tax payment easier than a lump sum.

This was all about who should pay estimated taxes. Moving further, let's know what taxes the self-employed pay. 

Taxes Paid by Self-Employed People

As a self-employed individual, you are liable to pay an annual tax return. However, you generally every quarter you pay estimated taxes. Quarterly taxes usually consist of two categories:

  • Self-employment tax (Medicare and Social Security)
  • Income tax on the profits made by the business and any other income

Confused? Let us better understand with an example. Assume that in the 2024 tax year:

  • On gross income up to $168600, the rate of self-employment tax is 15.3%. Here, the tax rate includes 12.4% Social Security tax and 2.9% Medicare tax. If your income increases more than the specified limit, then a 2.9% Medicare tax will continue to be imposed, but Social Security will not be deducted.
  • Generally, higher earners, people with an income of $200000 and more, or married individuals with earnings of $250000 or more, are liable to pay 0.9% extra Medicare tax.

Further, as a business owner, to calculate your taxable income, it is done as follows:

  • Take your calculated annual total income. It is the total revenue you earned. Now, from this amount, subtract your business expenses and eligible tax deductions. For instance, the annual revenue you earned is $100000, and the business expenses are $30000. Here, your taxable income is $70000 ($100000 - $30000). 
  • For small business owners, the IRS has designed a full reference and listing guide. The Form 1040-ES is a worksheet that helps you calculate your taxable income and payments.
  • Once you use the form to determine your yearly taxes, divide the amount by four. This is your tax amount that you need to pay quarterly.

During the year, if your expenses or income change a lot, it may impact the quarterly taxes you paid. For instance:

  • You sign a big contract that increases your income.
  • Your business faces a drop in income as it loses a big customer.

In both scenarios, you need to check the worksheet before paying the quarterly taxes. Make sure to pay the right tax amount as per your earned income.

This is how self-employed people pay quarterly taxes. Moving ahead, let's know the qualified business income deduction under quarterly taxes.

Qualified Business Income Deduction

You get the chance to cut your income from self-employment. Through QBI deduction, you can claim a tax deduction on your self-employment income. This helps to cut up to 20% off your pass-through income from owning a small business or self-employment. You can apply this when filing for your tax return.

Using the QBI deduction, you can decrease the net amount of eligible items of deductions, income, gains, and losses connected to your business or trade. It means items such as capital losses and gains, interest income, and dividends, not mentioned in this calculation.

Further, to claim the QBI deduction, your taxable income for single filers should be less than $191950 or for joint filers should be less than $383,900 in 2024. In the 2025 tax year, the income limit is $197300 for single filers and $394600 for joint filers, respectively.

Moreover, to qualify for the business income deduction, first, you must find your income. Then, after subtracting the available deduction, report it on the IRS Form 1040. From there, you will be able to calculate your pass-through tax deduction.

This was all about the qualified business income deduction. Moving further, let's know the due date of quarterly taxes for 2025.

Due Date of Quarterly Taxes for 2025

The table below outlines the period of income earned and the associated due date for paying the quarterly taxes for 2025:

*Note: It is advisable, before paying the quarterly taxes, to verify the tax deadlines as, due to weekends or holidays, they vary slightly.

These are the due dates of quarterly taxes for the 2025 tax year. Moving ahead, let's know how to pay these taxes.
