Key Takeaways

  • Estimated taxes for business owners are quarterly payments made to the IRS and state tax agencies to cover income tax, self-employment tax, and other liabilities throughout the year.
  • Most LLCs, sole proprietors, S corporations, and partnerships must pay estimated taxes if they expect to owe $1,000 or more ($500 for C corporations).
  • Estimated tax payments are due four times a year—typically in April, June, September, and January.
  • Calculating estimated payments requires projecting annual income, deducting expenses, and applying current tax rates. Owners can use IRS Form 1040-ES or corporate worksheets to calculate and submit payments.
  • Paying on time avoids IRS underpayment penalties and helps smooth cash flow by preventing a large year-end tax bill.
  • Certain exceptions, such as sufficient withholding from other employment or safe harbor rules, can exempt businesses from quarterly payments.

LLC estimated tax payments should be paid by your business throughout the year to help reduce the impact at tax time. There are some important aspects of this process that all business owners should know.

What Are Estimated Tax Payments?

If you are a new small business owner, making sure you meet all of your tax obligations can take some getting used to, especially when you have a history of working for another person who has held out your taxes for you each payday. When you own a business, you have to deal with taxes more often than once a year. You will need to make estimated payments all year long. You are required to pay all throughout the year rather than only at tax time.

If you worked for an employer, he or she would take out your taxes all year long for you. As a self-employed individual, you will be responsible for these tax payments yourself. You are responsible for making your payments; the IRS is not going to warn you about when they are due. It may not be evident to you until it is time to pay your taxes at the standard time.

Many people do not pay estimated personal income taxes because enough money has been withheld all year. If your business shows a profit, you might want to pay your business taxes using its checking account. This will leave less questions for the IRS. The type of account you use to pay your estimated business taxes will be determined by the type of business you own.

Sole proprietorships can typically use any checking account to pay taxes. However, you will not want the IRS to ask questions about the separation of your personal and business expenses. LLCs and partnerships should use a business checking account unless the estimated taxes are paid on your personal return. You will need to speak to your tax preparer before you write your check.

If you do not currently have a separate account for your business, it is advisable to get one.

How Estimated Tax Payments Work

Estimated taxes for business owners are not a single annual bill — they’re quarterly payments based on the income your business earns throughout the year. Because taxes are a “pay-as-you-go” system, the IRS requires individuals and businesses without regular withholdings (like W-2 employees receive) to make these payments on a regular schedule.

These payments typically cover three main categories:

  1. Income tax – Federal and, in many cases, state income tax on business earnings.
  2. Self-employment tax – Covering Social Security and Medicare contributions for business owners.
  3. Other taxes – Such as alternative minimum tax (AMT) or certain excise taxes if applicable.

Payments are generally due on a quarterly schedule:

  • April 15 – for income earned January–March
  • June 15 – for income earned April–May
  • September 15 – for income earned June–August
  • January 15 (following year) – for income earned September–December

If these dates fall on a weekend or holiday, the deadline moves to the next business day.

Who Has to Pay Estimated Tax Payments?

  • Sole proprietors, partnerships, S corps, shareholders and single-member LLCs that choose to be taxed as a sole proprietor or S corp, or a multi-member LLC that chooses to be taxed as a S corp or partnership: If you think you are going to owe $1000 or more in taxes, you should plan to make estimated payments to the federal and state government. The exception to this is if your withholdings and tax credits equal at least as much as your taxes the year prior, you do not need to make a federal estimated payment.
  • C corporations and multi-member LLCs that choose to be taxed like a C corp: As the owner of a corporation, you will have to make estimated payments on your taxes if you think you will owe over $500.
  • For partnerships, multi-member LLCs or S corps, your profit shares will be displayed on Schedule K-1 with your personal tax return.

How to Calculate Your Estimated Payments

Calculating estimated taxes for business owners involves projecting your annual income and dividing that liability into quarterly installments. This can be done in a few steps:

  1. Estimate annual income – Use prior year figures or current-year projections to forecast your total income.
  2. Subtract deductible expenses – Include operating costs, depreciation, and other qualified deductions.
  3. Calculate taxable income – Apply the appropriate tax rate based on your filing status and entity structure.
  4. Divide by four – Split the total estimated tax due into four quarterly payments.

Many business owners use IRS Form 1040-ES (for sole proprietors, single-member LLCs, and partnerships) or Form 1120-W (for C corporations) to estimate and pay quarterly amounts. These forms include worksheets to help calculate tax liability and generate payment vouchers.

It’s a good idea to slightly overestimate rather than underpay — underpayment penalties can apply if you fall short. The IRS “safe harbor” rule can also help you avoid penalties if you pay at least:

  • 90% of the current year’s tax liability, or
  • 100% of the prior year’s tax liability (110% if your AGI was over $150,000).

Exceptions to Making Estimated Tax Payments

The following questions can help determine if you will need to pay estimated taxes:

  • Do you think that you will owe $1000 or more in taxes when you subtract your income tax withholding and credits from your overall tax? If no, you will not need to pay an estimated tax. If so, answer the next question.
  • Do you think your income tax and withholding credits will be at minimum 90-percent of your taxes owed? If no, you will not have to pay estimated taxes. If yes, move on to the next question.
  • Do you think your income tax withholding and credits will be at minimum 100-percent of your taxes displayed on your last return? If no, you will not pay estimated tax. If yes, you will need to pay the estimated tax.

It is possible that you can use the withholding from another job or from the job held by your spouse to prevent owing estimated taxes or an estimated tax penalty. Payroll withholdings are designed to be made evenly all year long, no matter when it is actually withheld. If you plan to have enough tax withheld at the end of the year, you could avoid estimated taxes.

Tips to Avoid Penalties and Stay Compliant

Falling behind on estimated tax payments can lead to interest charges and underpayment penalties. To stay compliant and minimize risk:

  • Set up a payment calendar: Mark all four quarterly due dates to avoid missed payments.
  • Use electronic payments: Pay through the IRS Electronic Federal Tax Payment System (EFTPS) for instant confirmation and recordkeeping.
  • Adjust payments mid-year: If income fluctuates significantly, recalculate estimated taxes for the remaining quarters.
  • Consider withholding strategies: If you or your spouse also earn W-2 income, increasing tax withholding from those paychecks can offset or eliminate the need for quarterly payments.
  • Consult a tax professional: A tax advisor can help ensure you’re not overpaying or underpaying, and assist with cash flow planning.

    You may face IRS underpayment penalties and interest. Making partial payments or catching up quickly can reduce the penalty amount.

  3. How do I make estimated tax payments?
    You can pay online through the IRS EFTPS system, by phone, or by mailing a check with a payment voucher from Form 1040-ES or 1120-W.
  4. What if my business income fluctuates during the year?
    You can recalculate and adjust your quarterly payments as income changes. This approach helps you stay closer to your actual liability.
  5. Are state estimated tax payments required too?
    Yes, most states require separate estimated tax payments if you meet certain income thresholds. Check with your state tax authority for specific requirements.
