Quarterly Estimated Taxes: What Self-Employed People in McKinney and Plano Need to Know

One of the biggest tax surprises for people who are newly self-employed is discovering that the IRS expects you to pay taxes four times a year, not once. If you came from a traditional job where taxes were withheld from every paycheck, the concept of quarterly estimated taxes can feel confusing and even a little alarming the first time you encounter it.

We speak with a lot of freelancers, independent contractors, and small business owners across McKinney, Plano, Richardson, and Frisco who ran into their first big tax bill because they did not know about estimated taxes until it was too late.

Why Quarterly Taxes Exist

The United States tax system is a pay-as-you-go system. When you work for an employer, they handle this for you by withholding federal income tax, Social Security, and Medicare from each paycheck. When you are self-employed, there is no employer doing that withholding. The IRS still wants their money throughout the year, so they require self-employed individuals to pay estimated taxes quarterly.

If you do not make these payments and you owe more than one thousand dollars at the end of the year, the IRS will charge you an underpayment penalty on top of whatever you owe.

Who Needs to Pay Quarterly Estimated Taxes

You generally need to make quarterly estimated payments if you expect to owe at least one thousand dollars in taxes for the year and your withholding from other sources will not cover at least 90 percent of your current year tax bill, or 100 percent of your prior year tax bill. This applies to freelancers, independent contractors, sole proprietors, partners in a partnership, S corporation shareholders who receive distributions, and rental property owners.

The Four Due Dates You Need to Know

• First quarter payment covers January through March and is due in mid-April.
• Second quarter payment covers April and May and is due in mid-June.
• Third quarter payment covers June through August and is due in mid-September.
• Fourth quarter payment covers September through December and is due in mid-January of the following year.

How to Calculate What You Owe

There are two main methods. The first is to estimate your actual current year tax liability and pay 25 percent each quarter. The second is the safe harbor method: simply pay 100 percent of what you owed in the prior tax year, spread across four equal payments. If your prior year adjusted gross income was above $150,000, the threshold is 110 percent. Following this method protects you from underpayment penalties even if your income rises significantly.

Setting Money Aside Throughout the Year

The discipline of paying quarterly taxes is really a discipline of cash flow management. A practical approach is to open a separate savings account specifically for taxes and transfer a percentage of every payment you receive into it immediately. Depending on your tax rate, somewhere between 25 and 35 percent is a reasonable amount to set aside. When a quarterly payment is due, the money is already sitting in that account waiting.

What Happens If You Miss a Payment

If you miss a quarterly payment or pay less than you should have, the IRS calculates a penalty based on the federal short-term interest rate plus three percent, applied to the underpaid amount for each day it was underpaid. If you realize mid-year that you have been underpaying, the best move is to increase your remaining quarterly payments rather than waiting until April to sort it out.
