Quarterly Tax Payments: What You Need to Know as a Small Business Owner

by | Apr 15, 2025 | Tax

As a small business owner, managing your taxes can feel overwhelming, especially when it comes to quarterly tax payments. Are you required to pay them? How do you calculate what you owe? Where do you make your payments? These are common questions we hear at Key2 Accounting, and we’re here to help.

Quarterly tax payments are a crucial part of running a business, ensuring you stay compliant and avoid penalties. Whether you’re a freelancer, independent contractor, or business owner in Fort Collins or Hawaii, or anywhere else in the US, understanding estimated taxes can save you time, money, and stress. Read on to learn what you need to know about quarterly taxes and how professional accounting consultants can simplify the process for you.

Who is Required to File Quarterly?

The IRS requires self-employed individuals and small business owners to make estimated tax payments if they expect to owe $1,000 or more in taxes for the year. This includes:

  • Freelancers and Independent Contractors
  • Sole Proprietors and Small Business Owners
  • S-Corporation Shareholders and Certain LLC Members

Unlike W-2 employees, who have taxes automatically withheld from their paychecks, self-employed individuals must calculate and pay taxes themselves. The IRS expects these payments four times a year—in April, June, September, and January—to cover income tax, self-employment tax, and any additional taxes owed.

Missing quarterly tax payments or underpaying can result in penalties and interest. If you’re unsure whether you need to pay estimated taxes, consulting with a CPA specializing in tax preparation can help you stay on track and avoid costly mistakes.

How to Calculate Your Quarterly Taxes

Estimating your quarterly tax payments requires calculating:

  1. Your Expected Annual Income: Determine your projected income for the year.
  2. Your Tax Rate: Self-employment tax is typically 15.3% (covering Social Security and Medicare), plus federal and state income tax rates.
  3. Deductions and Credits: Factor in deductions to lower your taxable income (more on this below).
  4. Divide by Four: Once you estimate your total tax liability, divide it into four equal payments.

The IRS provides Form 1040-ES to help business owners estimate and pay their taxes accurately. However, tax laws change frequently, and working with professional accounting consultants can help ensure your calculations are correct.

What Has the Potential of Being a Deduction for a Small Business?

One of the advantages of running a business is that you can deduct certain expenses, reducing your taxable income. Some common deductions include:

  • Home Office Deduction – If you work from home, a portion of your rent, utilities, and internet may be deductible.
  • Business Equipment and Supplies – Computers, office furniture, and software used for work can often be written off.
  • Vehicle Expenses – Mileage and maintenance costs related to business use may be deductible.
  • Health Insurance Premiums – Self-employed individuals may qualify for a deduction on their premiums.
  • Marketing and Advertising – Website costs, digital ads, and promotional materials are typically tax-deductible.

Properly tracking your deductions can significantly lower your tax burden. Our business accounting services at Key2 Accounting help clients maximize deductions while staying compliant with tax laws.

Where Can You Pay Your Quarterly Taxes?

The IRS offers multiple ways to pay estimated taxes:

  • Online via IRS Direct Pay – A fast, secure method to pay directly from your bank account.
  • Electronic Federal Tax Payment System (EFTPS) – A free service that allows business owners to schedule and track payments.
  • Mailing a Check or Money Order – Using Form 1040-ES, you can mail payments to the IRS.
  • Credit or Debit Card Payments – Though convenient, these may come with processing fees.

Each method has advantages, and the best option depends on your preferences and business needs. Late payments can result in penalties, so setting up automated payments or working with an accountant ensures you never miss a deadline.
