Form CT-183: New York Transportation and Transmission Corporation Franchise Tax Return Explained (2025)

Form CT-183 is the New York State Department of Taxation and Finance return that certain transportation and transmission corporations use to report and pay franchise tax based on their gross earnings. Unlike the standard corporate franchise tax computed on net income, this return calculates tax liability using gross receipts earned from specific transportation or transmission activities conducted within New York State.

The form applies to a fairly narrow group of businesses. If your company is organized as a transportation corporation (think trucking, bus lines, or similar carriers) or a transmission corporation (pipeline, telegraph, or related infrastructure businesses) and you generate gross earnings from operations in New York, you’re likely required to file CT-183 rather than the general business corporation franchise tax return. Some businesses may need to file both CT-183 and a companion form, CT-184, depending on how their earnings are structured between gross earnings tax and additional franchise tax components.

Who Needs to File CT-183

Any transportation or transmission corporation doing business, employing capital, owning or leasing property, or maintaining an office in New York State typically falls under this filing requirement. This includes both domestic corporations formed in New York and foreign corporations authorized to operate there. The tax is triggered by the privilege of conducting business in the state, not just by having a physical presence, so companies with even limited New York operations should review whether this return applies to them.

It’s worth noting that this filing category is distinct from utility corporations, which file under a separate framework. If your business is a utility rather than a transportation or transmission company, you’ll want to look instead at Form CT-186, which covers utility corporation franchise tax on gross earnings in New York for the same tax year.

When Is Form CT-183 Used

CT-183 is filed annually, following the corporation’s tax year, and is due based on the same general franchise tax filing calendar the state uses for corporate returns. Corporations need to file even in years where gross earnings are minimal, since the filing obligation is tied to corporate status and business activity in New York rather than a specific earnings threshold. Late or missed filings can result in penalties and interest, so it’s a good idea to mark the deadline as soon as the tax year opens.

How to Fill Out and Submit the Form

The 2025 version of CT-183 is an AcroForm PDF, meaning you can type your entries directly into the fields on your computer before printing or saving the completed document. You’ll need your corporation’s identifying information (EIN, DOS ID if applicable), gross earnings figures broken down by category of transportation or transmission activity, and any allocation percentages if your business operates both inside and outside New York State.

Before diving into the gross earnings calculations, gather your financial records for the full tax year, including revenue statements segmented by service type. This will make it easier to correctly allocate earnings subject to the New York tax versus earnings generated elsewhere. Many corporations find it helpful to cross-check gross earnings reporting against other compliance paperwork they maintain, similar to how a business expenses worksheet helps organize deductible costs for other tax filings.

Once completed, the form is submitted directly to the New York State Department of Taxation and Finance following the instructions printed on the return. If your corporation also participates in local business tax programs, it may be worth reviewing a city/county business tax program participation guide to understand how state and local filings interact for transportation-related businesses.

Because gross earnings tax calculations can get complicated when a corporation operates across multiple states, many filers choose to have an accountant familiar with New York franchise tax review the return before submission, particularly in the first year a business becomes subject to this filing requirement.
