Quarterly Estimated Taxes: A Simple Guide for Texas Small Businesses
If you're self employed or run a small business in Texas, you've probably heard the term "quarterly estimated taxes" and felt a little unsure about whether it applies to you. It's one of the most misunderstood parts of running a business, and missing a payment can mean an unexpected penalty at tax time, even if you end up owing nothing extra overall.
The good news is that the rules are more straightforward than they sound, and Texas business owners have one real advantage here: since Texas has no state income tax, you only have to think about federal estimated payments, not a second set of state deadlines. Below is what quarterly estimated taxes actually are, who needs to pay them, and how to stay ahead of the deadlines. If you'd rather have this handled for you, our tax preparation and bookkeeping services can calculate and track these payments as part of your regular bookkeeping.
What Are Quarterly Estimated Taxes
When you're a W-2 employee, your employer withholds income tax and payroll tax from every paycheck automatically. When you're self employed, a partner in a business, or an S-corp shareholder receiving pass through income, there's no employer doing that withholding for you. The IRS still expects to collect tax throughout the year rather than in one lump sum in April, so it requires business owners to estimate their tax liability and pay it in four installments.
This isn't limited to income tax. If you're self employed, your estimated payments also need to cover self employment tax, which funds Social Security and Medicare and runs 15.3 percent on top of regular income tax. It's easy to underestimate a quarterly payment by forgetting this piece is included.
Who Actually Needs to Pay
Generally, you need to make estimated tax payments if you expect to owe at least $1,000 in federal tax for the year after subtracting withholding and refundable credits. This typically applies to:
Sole proprietors and single member LLC owners
Partners in a partnership
S-corp shareholders receiving distributions
Independent contractors and freelancers
Landlords with net rental income
Anyone with significant investment income and little to no withholding
If you also have a W-2 job on the side, withholding from that paycheck counts toward your total obligation. Some business owners use this to their advantage by increasing withholding at their regular job late in the year to cover a shortfall, since withholding is treated as if it were paid evenly across all four quarters no matter when it's actually withheld.
When Payments Are Due
The IRS splits the year into four payment periods, and the periods aren't evenly sized, which trips a lot of people up. For the current tax year, the deadlines are:
Q1: April 15
Q2: June 15
Q3: September 15
Q4: January 15 of the following year
Notice that Q2 only covers two months while Q3 covers three. The IRS calendar doesn't map neatly onto real calendar quarters, so it's worth marking these dates directly rather than assuming they fall every three months.
How Much You Actually Need to Pay
You don't have to calculate your tax liability down to the dollar to avoid a penalty. The IRS gives you a safe harbor: as long as your total withholding and estimated payments for the year equal at least one of the following, you won't owe an underpayment penalty even if you end up owing more when you file:
90 percent of your current year's total tax liability, or
100 percent of your prior year's total tax liability (110 percent if your prior year adjusted gross income was over $150,000)
Most business owners use the prior year method because it's a known number. If your business grows significantly during the year, paying based on last year's tax bill means you might owe a larger balance in April, but you still won't owe a penalty for underpaying quarterly, as long as you hit that 100 or 110 percent threshold. The IRS Form 1040-ES instructions include a worksheet that walks through the full calculation if you want to estimate your current year liability directly instead.
What Happens If You Miss a Payment or Underpay
The underpayment penalty isn't a single flat fee. It's calculated based on how much you underpaid and for how long, using the IRS's current underpayment interest rate, which adjusts quarterly. Missing one payment doesn't erase the requirement for the rest of the year. It just means that quarter accrues a penalty while the others are evaluated on their own.
If you realize partway through the year that you're behind, the best move is to make a catch up payment as soon as possible and reassess your remaining quarters, rather than waiting until the next scheduled date. The penalty is calculated from the original due date forward, so the longer a payment sits unpaid, the more it accrues.
A Few Practical Tips
Set aside a percentage of every payment you receive into a separate account throughout the quarter, rather than trying to come up with the full amount right before the deadline
Revisit your estimate if your income changes significantly partway through the year
Keep your bookkeeping current so you actually know what you've earned and spent when it's time to calculate a payment
Don't forget that self employment tax is part of the calculation, not a separate, optional add-on
