Estimated tax payments can feel confusing, especially if you’re new to managing your own taxes or running a business. But knowing what they are, who needs to pay them, and how to calculate them can save you from unexpected tax bills and penalties. At The Winston CPA Group, we help entrepreneurs, freelancers, creatives, athletes, and business owners understand and manage their estimated taxes clearly and confidently.
In this post, I’ll explain estimated tax payments in plain language. You’ll learn who needs to make them, what types of income usually require estimated payments, when these payments are due, and how to calculate them. I’ll also cover important rules like the federal safe harbor, the $1,000 tax threshold, and what happens if you underpay. Plus, I’ll share a simple example to help you see how it works in practice.
What Are Estimated Tax Payments?
Estimated tax payments are periodic payments you make to the IRS throughout the year. They cover income that isn’t subject to withholding, like self-employment income, rental income, investment earnings, or other sources where taxes aren’t automatically taken out.
If you don’t pay enough tax during the year, either through withholding or estimated payments, you could owe a big amount when you file your tax return. Worse, you might face penalties for underpayment.
Estimated taxes help you spread your tax payments evenly over the year, so you avoid surprises and penalties.
Who Needs to Make Estimated Tax Payments?
You may need to make estimated tax payments if you expect to owe at least $1,000 in tax after subtracting your withholding and refundable credits. This usually applies to people who:
Are self-employed, freelancers, or independent contractors
Own a small business or are entrepreneurs
Earn income from investments, dividends, or capital gains
Receive rental income as landlords
Are athletes earning NIL (Name, Image, Likeness) or endorsement income
Have income that doesn’t have enough tax withheld from paychecks
If you have a regular job with W-2 income, your employer usually withholds taxes from your paycheck. This withholding counts toward your tax bill. But if your withholding isn’t enough to cover your total tax, you might still need to make estimated payments.
Types of Income That Create Estimated Tax Obligations
Here are common income types that often require estimated tax payments:
Self-employment income: Freelancers, consultants, and business owners usually don’t have taxes withheld, so they pay estimated taxes.
Investment income: Interest, dividends, and capital gains from stocks or other investments.
Rental income: Landlords who receive rent payments.
Retirement income: Some pensions or distributions from retirement accounts.
Athlete and endorsement income: Earnings from NIL deals or sponsorships.
Other income: Alimony, prizes, or gambling winnings that don’t have withholding.
If your income comes from multiple sources, you’ll need to consider all of them when figuring out your estimated tax payments.
When Are Estimated Tax Payments Due?
Estimated tax payments are generally due four times a year. But the deadlines don’t split the year into four equal quarters. Instead, they cover specific income periods:
1st payment: April 15 — covers income from January 1 to March 31
2nd payment: June 15 — covers income from April 1 to May 31
3rd payment: September 15 — covers income from June 1 to August 31
4th payment: January 15 of the following year — covers income from September 1 to December 31
If a due date falls on a weekend or holiday, the deadline moves to the next business day.
Missing these deadlines or underpaying can lead to penalties and interest charges.
How Are Estimated Tax Payments Calculated?
Calculating estimated taxes involves estimating your total income, deductions, and credits for the year. Then you figure out how much tax you expect to owe and subtract any withholding or credits.
Here’s a simple way to think about it:
Estimate your total income for the year.
Subtract deductions and credits to find your taxable income.
Use the IRS tax rates to calculate your expected tax.
Subtract any tax withheld from your paychecks.
Divide the remaining tax by four to get your quarterly estimated payment.
The IRS also offers an annualized income installment method. This method lets you calculate payments based on your actual income earned during each period, which can help if your income varies throughout the year.
Federal Safe Harbor Rules and the $1,000 Threshold
The IRS has safe harbor rules to help you avoid penalties for underpayment:
Pay at least 90% of the current year’s tax liability through withholding and estimated payments, or
Pay 100% of the previous year’s tax liability (110% if your adjusted gross income was over $150,000)
If you meet one of these safe harbor rules, you won’t face penalties even if you owe more tax when you file.
Also, you generally don’t need to make estimated payments if you expect to owe less than $1,000 after subtracting withholding and refundable credits.
How Estimated Taxes Affect Different Income Earners
Entrepreneurs, Freelancers, and Business Owners
If you run your own business or work as a freelancer, taxes aren’t automatically withheld. You need to estimate your income and pay taxes quarterly. This includes self-employment tax, which covers Social Security and Medicare.
Creatives and Independent Contractors
Artists, writers, designers, and contractors often receive payments without tax withholding. Estimated payments help avoid a large tax bill at year-end.
Investors and Landlords
Income from dividends, interest, capital gains, and rental properties usually doesn’t have withholding. Estimated payments keep you current on your tax obligations.
Athletes with NIL or Endorsement Income
Athletes earning from endorsements or NIL deals often receive income without withholding. Estimated payments help manage taxes on these earnings.
People with W-2 Income and Withholding
If you have a regular job, your employer withholds taxes. But if you have other income sources or your withholding is too low, you may need to make estimated payments to cover the gap.
What Happens If You Underpay Estimated Taxes?
If you don’t pay enough tax during the year, the IRS may charge penalties and interest on the underpaid amount. The penalty depends on how much you underpaid and for how long.
You can avoid penalties by following the safe harbor rules or by making accurate estimated payments on time.
Simple Example of Calculating Estimated Taxes
Let’s say you expect to earn $80,000 this year from freelancing. You estimate your deductions and credits will be $20,000, so your taxable income is $60,000.
Using the IRS tax brackets, your estimated tax might be around $8,000 for the year. You don’t have any withholding.
To avoid penalties, you divide $8,000 by 4 and pay $2,000 each quarter as estimated tax payments.
