One question I hear often is whether a taxpayer needs to pay the Internal Revenue Service (IRS) estimated tax payments throughout the year. Estimated tax payments—also known as quarterly tax payments—are typically made for the current tax year by individuals, including sole proprietors, partners and businesses that do not have their taxes withheld in paychecks. In this post, we’ll look a little more in depth at quarterly tax payments.

Generally, individuals need to make estimated or quarterly tax payments if they expect to owe tax of $1,000 or more when their return is filed. Estimated taxes are calculated using IRS Form 1040-ES to determine the taxes they will owe. Corporations typically use Form 1120-W to figure estimated tax. Use your adjusted gross income, taxable income, taxes, deductions and credits for the year you are calculating. If your income for the year is close to what it was the previous year, you could use the prior year’s federal tax return as a guide.

It’s important to estimate your payments as close as possible in order to avoid under-payment penalties. Typically, most taxpayers can avoid this penalty if they owe less than $1,000 in tax after subtracting their withholdings and credits, or if they paid at least 90% of the tax for the current year, or 100% of the tax shown on the return for the prior year, whichever is smaller.

When are estimated tax payments due?

Estimated taxes are divided into four quarterly payments. Below are the federal quarterly estimated tax payment deadlines for tax year 2020. The deadlines are generally the same for each year.

April 15, 2020 – Quarter 1 Taxes (January 1 – March 31)
June 15, 2020 – Quarter 2 Taxes (April 1 – May 31)
September 15, 2020 – Quarter 3 Taxes (June 1 – August 31)
January 15, 2021 – Quarter 4 (September 1 – December 31)

How do I pay federal estimated taxes?

There are various methods for making quarterly estimated tax payments, with the following being the most common.

  • If you overpaid on your 2019 tax return, you can apply that overpayment amount as a credit to your 2020 estimated taxes
  • Mail your payment with payment voucher
  • Pay by phone or online
  • Pay with electronic funds withdrawal with your 2019 e-filed return

Visit the IRS website for more information about how to pay and to obtain your payment vouchers.

How do I find out if I need to pay estimated taxes for previous years?

If you’re not sure whether you owe the IRS quarterly tax payments for previous tax years, you can download a transcript of your past tax returns online. This will tell you if you’ve paid estimated taxes or owe for previous years.

It can be tricky to determine whether you owe estimated taxes, but it’s important to stay on top of this so you do not owe the IRS penalties. Consult with a tax attorney or experienced tax professional that can help you navigate quarterly tax payments and work with you and the IRS so you don’t pay more than you owe.

I can't recommend Allison enough! She helped me successfully navigate a stressful EDD audit with expertise and grace. Not only is she incredibly smart and thorough, but she's also genuinely kind—something you don’t always expect from an attorney. Her support and guidance made all the difference. If you need a tax attorney who knows her stuff and truly cares, she's the one to call!

2024- Working with Allison has been an incredibly smooth experience both times I’ve worked with her. Her expert advice and the support she provides are outstanding, and we’ve had nothing but positive results each time. 2020- I was so impressed with her work during an EDD audit. I would HIGHLY recommend Allison to anyone going through an EDD Audit. From the very first 3 minutes of speaking with her, she was super helpful and professional, while also making me feel like I was talking to a friend, which really helped calm my anxiety. Allison was dedicated to helping us achieve the best possible outcome and was honest about all scenarios, even preparing us for the worst. We ended up with the VERY best outcome because of how she guided us through the process and made sure we had everything ready to tell our story to the auditor. If you want someone who truly listens, understands your business, and will be your biggest advocate, call Allison now! Be ready because she’s quick to respond with both calls and emails.

We retained the services of Allison Soares for a recent IRS audit. The IRS was claiming we owed an exorbitant amount of money. After interviewing several qualified attorneys, Allison was the obvious choice. During this very stressful time for our family, we appreciated how knowledgeable and responsive she was from the very first call. Her professionalism and commitment to our case was truly impressive. She pointed out a few critical points, that another attorney may have missed, which we believe helped our case immensely. She guided us through this complicated process with great success and we could not have been happier with the outcome of the audit. We are 100% satisfied with her work and would highly recommend her to anyone seeking legal tax advice. Thank you so much Allison, we are truly grateful for all your hard work.
