Connecticut Business Taxes for LLCs

How Your LLC Will Be Taxed

In this guide, we’ll cover the main business taxes required in Connecticut, including sales, self-employment and federal taxes. The profits of an LLC aren’t taxed at the business level like C Corporations. Instead, taxes are as follows:

Items 1, 2 and 3 fall under pass-through taxation for any LLC owners, managers or members who receive profits from the business. Profits are reported on federal and state personal tax returns.

State Taxes for LLCs

There are two main types of state tax you must pay to the Connecticut Department of Revenue: sales and income.

Connecticut Sales Tax

If you sell physical products or certain types of services, you may need to collect sales tax and then pay it to the Connecticut Department of Revenue Services. Sales tax is collected at the point of purchase and varies depending on the region, county or city where your business is located.

Most states don’t levy sales tax on goods that are considered necessities, such as food, medications, clothing or gas. Use our sales tax calculator to determine how much you'll need to pay, but also check with your accountant and the Department of Revenue Services to confirm whether your business is required to collect Connecticut sales tax and, to ensure you pay the correct amount.

Connecticut Income Tax

As a business owner, you’ll need to pay Connecticut income tax on any money you pay to yourself. These earnings flow through to your personal tax return. You’ll be taxed at Connecticut's standard rates, and you’ll also get to apply regular allowances and deductions.

Any salaried employees will also need to pay state tax on their income.

The Connecticut income tax rate varies between 3 percent and 6.99 percent, depending on how much you earn.

How to get a State Tax ID for Connecticut

In order to pay state taxes, you must apply for a Connecticut tax registration number. You can obtain a number by registering your business online. The fee(s) you'll pay will depend on the type(s) of tax your business will collect.

Federal Taxes for LLCs

As the owner of an LLC, you must pay self-employment tax and federal income tax, which are taxed as “pass-through” income.

Federal taxes can be complicated, so be sure to speak to your accountant or professional tax preparer to ensure that your Connecticut LLC is paying the correct amount.

Federal Self-Employment Tax

All members or managers who take profits out of the LLC must pay self-employment tax. This tax is administered by the Federal Insurance Contributions Act (FICA) and covers Social Security, Medicare and other benefits. The current self-employment tax rate is 15.3 percent.

You’ll be able to deduct some of your business expenses from your income when calculating how much self-employment tax you owe.

Pay Less Self-Employment Tax by Treating Your LLC As an S Corporation

The Internal Revenue Service allows an LLC to be treated as an S Corporation for tax purposes, provided your business meets certain requirements. This can help you reduce the amount of self-employment tax you pay by allowing you to declare some of your income as salary and other income as distributions or withdrawals.

You do this by filing Form 2553, also known as an S Corp Election form, with the IRS. Incfile can also file the form for you. Use our S Corp Tax Calculator to get an idea of how much money you could save with this election.

Consult with your accountant or tax advisor for more information on reducing your LLC self-employment tax through an S Corporation tax election.

Federal Income Tax

You must also pay regular federal income tax on any earnings you take out of your LLC. The amount of income tax you pay depends on your earnings, current income tax bracket, deductions and filing status.

You only pay federal income tax on profits you take out of the business, less certain deductions and allowances. This includes your tax-free amount, plus business expenses and other deductions for areas such as healthcare and some retirement plans.

Speak to your accountant for more information.

Employee and Employer Taxes

If you pay employees, there are some slightly different tax implications. Speak to your accountant to get clear guidance for your unique situation.

Employees May Need to File Tax Returns

Regardless of whether you withhold federal and state income tax, your employees may need to file their own tax returns.

Employee Insurance and Other Requirements

You may also need to pay insurance for any employees, such as employee compensation insurance or unemployment tax.

Other Taxes and Duties for Your LLC

Depending on your industry, you may be liable for certain other taxes and duties. For example, if you sell gasoline, you may need to pay a tax on any fuel you sell. Likewise, if you import or export goods, you may need to pay certain duties.

Speak to your accountant about any other taxes or duties you may need to withhold or pay.

Estimated Taxes

Most LLCs must pay estimated taxes throughout the year, depending on the amount of profit and income you expect to make. The most common types of estimated tax are:

Most LLCs will pay estimated taxes four times a year. Learn more on the IRS website, and speak to your accountant for more information.
