Connecticut LLC Taxes

The Connecticut LLC taxes encompass a diverse range of types that owners are required to pay, resulting in a significant variation in the annual expenses. 

Some of these taxes paid by LLC owners encompass:

Federal Income Taxes

The Internal Revenue Service (IRS) offers various options for the tax treatment of your LLC. If your LLC is a Single-Member LLC, it’s treated as a Disregarded Entity, meaning the IRS doesn’t expect the LLC to file its own federal income tax return. Instead, the owner files the return and pays the taxes. The tax method depends on the owner’s identity: as an individual, the LLC is taxed like a Sole Proprietorship, and if owned by another company, it’s taxed as a branch of the parent company.

Multi-Member LLC Taxes

For LLCs with multiple owners, the default tax status is Partnership. The LLC files a 1065 Partnership Return and provides a Schedule K-1 to owners, reporting their share of profits. Owners pay income taxes on their personal tax return (Form 1040) based on K-1 income.

Husband and Wife LLC Taxes

In certain states, a husband and wife LLC can opt to file taxes as a Single-Member LLC or Qualified Joint Venture rather than a Multi-Member LLC. This is applicable in community property states. However, some states, like Connecticut, don’t allow Qualified Joint Ventures.

Electing Corporate Taxation

Apart from default statuses, an LLC can choose to be taxed like a Corporation by filing either Form 2553 (S-Corporation) or Form 8832 (C-Corporation). 

S-corporation status can reduce self-employment taxes for established businesses with profits, while C-corporation status may benefit larger employers for healthcare fringe benefits.

Connecticut State Income Tax

For Single-Member LLCs in Connecticut, the LLC doesn’t file a state return; the owner includes LLC profits/losses in their personal state return. Multi-member LLCs may file a state-level Partnership return, and owners report profits/losses in personal state returns. Specific business taxes apply to certain industries.

Local Income Tax

Connecticut LLCs might need to pay local income taxes to municipalities. Hiring an accountant is recommended for preparing and filing local income taxes, and checking local requirements is advisable.

Connecticut Sales Tax

Selling products in Connecticut may require collecting sales tax with a Seller’s Permit from the Department of Revenue Services. Register online or by mail. Sales tax registration is vital for retail sales, and permits vary in nomenclature.

Connecticut LLC Payroll Taxes

LLCs with employees in Connecticut must handle payroll taxes, including federal and state income tax withholding, Social Security and Medicare taxes, unemployment taxes, and more. Employers register for withholding tax and other obligations, with professional help often advised due to complexity and potential penalties.
