If you earn income through your own business, your tax bill does not wait until April. The IRS expects payment as you earn, throughout the year. Quarterly Estimated Tax (QTE) payments are how that works, and understanding them is the difference between a predictable year and a surprise at filing time.
Both LLC and S Corp members make quarterly estimated payments, though the amount works differently depending on your entity type.
What quarterly estimated tax payments are
Quarterly Estimated Tax payments are payments you make to the IRS, and to your state if it has an income tax, spread across the year rather than all at once when you file.
Your business income passes through to your Individual Tax Return (ITR), and unlike a paycheck from an employer, most of it has no tax withheld automatically. Quarterly estimates fill that gap. Paying as you go smooths your cash flow and, in most cases, can help you avoid underpayment penalties when you file.
When they are due
Federal estimated payments generally follow the schedule below. Because dates shift for weekends and holidays, confirm the current year's deadlines on IRS.gov or check your Collective dashboard.
| Quarter | Income period | Federal due date |
|---|---|---|
| Q1 | January 1 to March 31 | April 15 |
| Q2 | April 1 to May 31 | June 15 |
| Q3 | June 1 to August 31 | September 15 |
| Q4 | September 1 to December 31 | January 15 of the following year |
If a due date falls on a weekend or federal holiday, it moves to the next business day.
State deadlines usually mirror the federal ones, but not always. California, for example, does not require a Q3 payment and weights its four installments unevenly. Because state rules vary, check the requirements for the state where you file.
Who owes them, and how your tier affects the amount
Quarterly estimates are a personal tax obligation, even though the income comes from your business. Federal payments use your personal Social Security number, not your business EIN. That catches people off guard, so it is worth knowing before you reach the IRS payment screen.
How much you owe each quarter depends on your tier:
- LLC tier: Your business profit is reported on Schedule C as part of your ITR, and no tax is withheld anywhere along the way. Your quarterly estimates generally cover the full amount, including self-employment tax on your net business income.
- S Corp tier: You pay yourself through owner payroll, and income and employment taxes are withheld from those paychecks. Your quarterly estimate accounts for that withholding, so the amount left to pay directly is often smaller than it would be on the LLC tier. Distributions and other income not covered by payroll are still part of the calculation.
Entity-level taxes your business owes, such as franchise taxes in some states, are separate from your personal estimates. Those appear on their own tab in your dashboard and are covered in their own articles.
What Collective does, and what you do
Collective calculates your estimate. Each quarter, your Collective team works out what you owe federally and to your state based on your books, your tax profile, and whatever you tell us about income earned outside your business. We also estimate entity-level franchise taxes and fees where they apply, and we keep a record of every payment you log.
You make the payment. You choose which calculation method we use, you pay the IRS or your state directly at their own site, and you record the payment in your dashboard afterward.
Collective does not debit your account for a tax payment. Every payment originates with you.
Two things follow from that, and they are worth knowing before your first quarter:
- Nothing syncs back from the IRS. An estimate keeps showing as due until you record the payment yourself.
- Because Collective does not pay on your behalf, we cannot miss a deadline for you. We also cannot meet one for you.
The two ways your estimate can be calculated
When you review your estimate, the first question asks which of two approaches you prefer.
- Level, penalty-safe payments. Known as the IRS safe harbor method, this bases your payments on last year's tax, so all four installments are the same and predictable.
- Payments that track this year. This uses your actual figures from the current year, which targets what you are likely to owe rather than what you owed last year.
Both methods are accepted by the IRS, and you can switch between them any quarter. Which one suits you depends on how steady your income is and how much you value predictability over precision. That decision belongs to you, with input from your Collective team or your own tax advisor.

Common misconceptions
"My business pays these, so I should use my EIN." Federal estimated payments are personal and use your Social Security number. Using your EIN can misdirect the payment.
"Collective pays them for me." Collective calculates the amount and tracks what you have paid. The payment itself is always yours to make.
"I paid, so my dashboard should update." The IRS does not send confirmation back to Collective. Recording the payment in your dashboard is what closes the loop.
"If I skip a quarter, I can make it up in April." Paying late in the year does not always undo an earlier shortfall, because penalties can be assessed by quarter. If you have missed a payment, reach out and your Collective team can help you plan the next one.
