When you run an LLC, no employer takes tax out of your pay. That sounds like freedom until April arrives and the bill for a whole year is due at once. The US tax system works on a pay-as-you-go basis, which means quarterly taxes for LLC owners are not optional extra paperwork. They are how the IRS expects you to pay tax on business income during the year it is earned.
If you expect to owe at least $1,000 in federal tax after withholding and refundable credits, the IRS generally requires estimated tax payments. For most single-member LLC owners, that test is easy to meet once the business turns a real profit. This guide covers the 2026 dates, the forms, a simple way to work out how much to set aside, and the safe harbor rule that can protect you from a penalty even if your estimate is not perfect.
Quarterly Taxes for LLC Owners: Who Has to Pay
Your LLC itself does not change the basic rule. A single-member LLC is usually taxed as a sole proprietorship, so the owner reports profit on Schedule C and pays estimated tax as an individual. A multi-member LLC is usually taxed as a partnership, and each partner pays estimated tax on their share of the profit, whether or not that cash was actually paid out. That point catches people out: you can owe tax on profit that is still sitting in the business bank account. For the wider picture, see our LLC taxes guide.
An LLC that elects S corporation tax treatment is different. The business files its own return, and the owner-employee normally receives a salary with withholding. Even then, owners may still need estimated payments on other income not covered by salary withholding.
You do not need estimated payments if your total tax for the year will be under $1,000 after withholding and credits, or if you had no tax liability for the previous full year and were a US citizen or resident for all of that year. Those exceptions help new businesses in quiet early months, but they do not last once income grows.
The 2026 Due Dates, and Why the Quarters Are Uneven
For the 2026 tax year, the four federal due dates for calendar-year filers are April 15, 2026, June 15, 2026, September 15, 2026, and January 15, 2027. If a date falls on a weekend or a federal holiday, the deadline moves to the next business day. You can also skip the January payment if you file your 2026 return by February 1, 2027 and pay the full balance with it.
The periods behind those dates are not four equal quarters. The first payment covers January 1 to March 31. The second covers only April 1 to May 31, just two months. The third covers June 1 to August 31. The fourth covers September 1 to December 31, a full four months. So the second payment can feel early and the last one can feel large, because it covers the busy end of the year.
Put all four dates in your calendar at the start of the year, along with your state estimated tax dates if your state charges income tax. States run their own schedules and forms, and a federal payment does not cover a state bill. Clean books make this far easier: if income and expenses are up to date, each payment takes minutes rather than a weekend of hunting for receipts. See LLC bookkeeping basics for a clean-books routine.
How Much to Set Aside
There is no single percentage that fits every LLC, because income tax depends on your total income, filing status and deductions. Still, a plain starting point helps. Many self-employed owners set aside 25 to 30 percent of each payment they receive into a separate savings account, then adjust once they know their real tax rate. That range is a planning habit, not a tax rule, and it often covers both income tax and self-employment tax for owners in the middle income brackets.
Self-employment tax is the part new owners most often forget. It is 15.3 percent, made up of 12.4 percent for Social Security and 2.9 percent for Medicare, and it applies to 92.35 percent of your net self-employment earnings. So on $50,000 of net profit, the amount subject to self-employment tax is $46,175, and the tax itself is about $7,065. Half of that tax is then deductible when you work out your income tax.
A worked example shows how the pieces fit. Say your LLC makes $60,000 in net profit in a year and you have no other income. Your self-employment tax would be roughly $8,478. If your income tax came to about $4,500 after the standard deduction and the deduction for half your self-employment tax, your total federal bill would be near $12,978, or about $3,245 per quarter. The Form 1040-ES worksheet walks through this calculation step by step. Use it once at the start of the year, then redo it after any big change, such as a large contract or a slow quarter.
The Safe Harbor Rule That Can Save You From a Penalty
You do not have to predict your income to the dollar. The IRS safe harbor rule says you can avoid an underpayment penalty if your withholding plus estimated payments reach at least 90 percent of this year’s tax, or 100 percent of last year’s tax. If your adjusted gross income last year was over $150,000, or $75,000 if married filing separately, that second figure rises to 110 percent of last year’s tax.
For owners with steady or growing income, the prior-year figure is often the easiest target, because it is a known number from a filed return. Divide it by four and pay that amount each quarter. Meeting a safe harbor target does not mean you owe nothing at filing time. It means you avoid the underpayment penalty, even if a balance is still due with your return.
If your income is uneven, the annualised income method in the Form 1040-ES instructions lets you base each payment on income actually earned in that period, rather than four equal instalments. This suits seasonal businesses, but it needs accurate quarterly records.
Which Forms and How to Pay
For individuals, the main form is Form 1040-ES, Estimated Tax for Individuals. It includes the worksheet and four payment vouchers, one for each quarter. You only need a voucher if you pay by mail with a cheque. If you pay online, you do not need to send the form at all.
The easiest routes are IRS Direct Pay, which pulls from a bank account at no extra charge, and the Electronic Federal Tax Payment System (EFTPS), which lets you schedule payments in advance. You can also pay through your IRS online account, or by card through an approved provider, although card providers charge a fee. Keep the confirmation for every payment, with the date and amount, so you can match it to your return at filing time. See the IRS estimated tax rules for the official guidance.
Partnerships and S corporations file differently: a multi-member LLC taxed as a partnership generally uses Form 1065 for its annual return, and partners handle their own estimated payments, while an S corporation uses Form 1120-S. If you still need one, see our EIN guide. One habit ties this together: keep business money separate. Pay yourself from the LLC into a personal account, then set the tax share aside, or move it straight into a tax savings account when client money lands. A separate business bank account makes the whole routine visible at a glance.
What Happens If You Miss a Payment
Missing a payment does not stop you from filing, but it can add an underpayment penalty and interest, worked out quarter by quarter on Form 2210. The penalty rate is tied to the federal short-term rate plus 3 percentage points and is reset each quarter. Paying late is still better than not paying: the penalty stops growing on the amount once it is paid.
If you have already missed a quarter, pay as soon as you can, then recalculate the remaining payments rather than simply doubling the next one. Set a reminder two weeks before each due date. In that week, update your books, work out the quarter’s profit, check your safe harbor target, and pay. After two or three quarters, quarterly taxes for LLC owners become an ordinary routine, and April stops being a shock.
Do all LLC owners have to pay quarterly taxes?
No. You generally need estimated payments only if you expect to owe at least $1,000 in federal tax after withholding and refundable credits, and your withholding will not cover the required amount. Owners whose salaried job withholding already covers their LLC income may not need separate payments, but they should check with the Form 1040-ES worksheet.
What is Form 1040-ES used for?
Form 1040-ES is the IRS package for estimating and paying federal income tax and self-employment tax during the year. It holds the worksheet for working out your annual estimate and the vouchers for paying by mail. Online payments through Direct Pay or EFTPS do not require sending the form.
How do I avoid an underpayment penalty?
Pay at least 90 percent of this year’s tax, or 100 percent of last year’s tax, through withholding and estimated payments made on time. The prior-year figure rises to 110 percent if your adjusted gross income last year was over $150,000, or $75,000 if married filing separately. Meeting either target is the safe harbor rule.
What if my LLC income changes during the year?
Redo the Form 1040-ES worksheet for the remaining quarters. You can also use the annualised income method, which bases each payment on income actually earned in that period, instead of four equal payments.
Do I still need to pay state estimated taxes?
Often, yes. Most states with an income tax run their own estimated tax system with their own dates and forms. A federal payment to the IRS does not cover a state bill, so check your state tax agency’s schedule and add those dates to the same calendar.
