CT-3: General Business Corporation Franchise Tax

What Is a “Franchise” Tax?

In the tax world, a franchise tax is simply the price a corporation pays to exist and do business in a state. Think of it as a membership fee. New York's version is calculated under Tax Law Article 9-A and applies to most general business corporations.

It's not just based on profit. The state gives you a few different ways to calculate what you owe, and you end up paying the highest amount. The three “bases” are:

• Tax on Business Income: A percentage of your net income apportioned to New York.
• Tax on Capital: A percentage of your total business capital (basically, your net worth) apportioned to New York.
• Fixed Dollar Minimum: A flat fee based on your New York receipts — you pay this even if you have no income or capital.

The form runs your numbers through all three calculations. You pay the highest one.

Who Has to File This?

You have to file Form CT-3 if you're a corporation that falls under Article 9-A and fit into one of these categories:

• Domestic Corporations: If you were incorporated in New York, you're on the hook. You remain liable until you formally dissolve with the Department of State. You can't just walk away.
• Foreign Corporations Doing Business Here: If you were incorporated in Delaware or somewhere else, but you're doing business, employing capital, owning property, or maintaining an office in New York, you have to file.
• Corporations Hitting the Receipts Threshold: Even if you don't have a physical office, if you have over a certain amount of receipts sourced to New York, you're considered to be “deriving receipts” here and must file.
• Corporations That Are Partners in a Partnership: If your corporation is a general partner in a partnership that does business in New York, you're subject to tax.

Who doesn't file CT-3: Insurance companies, most transportation corporations, and non-stock not-for-profit corporations file under different articles of the tax law and have their own forms.

The Main Form vs. The “Combined” Form

Before you dive in, you need to know which version to use:

• Form CT-3: For a single corporation filing on its own.
• Form CT-3-A: The Combined Franchise Tax Return. If you're part of a group of corporations engaged in a unitary business that meet the ownership requirements (generally 80% or more), you may be required to file a combined return — essentially adding up the income and capital of multiple related corporations into one return to prevent profit-shifting.

One wrong checkmark on the combined filing question can cost you. If you have related corporations, check whether you're required to file CT-3-A before proceeding.

Walking Through the Form

The CT-3 is structured like a funnel — it starts with your federal numbers and gradually adjusts them to fit New York's rules.

Part 1 — General Information

The basics: your name, address, EIN, and the tax year. It also asks if this is a final return or an amended return. Check the boxes accordingly.

Part 3 — Tax on Business Income Base

Start with your federal taxable income (from your federal Form 1120). Add back certain items New York doesn't allow (like state taxes you deducted federally) and subtract others New York lets you exempt. This gives you your “entire net income,” which you then apportion to New York using the formula from Part 6.

Part 4 — Tax on Capital Base

Calculate your total business capital (your assets minus liabilities, with some adjustments). You then apportion that to New York and multiply by the capital tax rate.

Part 6 — Business Apportionment Factor

This is critical. You're telling New York what percentage of your business happens in New York — usually a fraction based on your receipts. Even if you think 100% of your business is in New York, you still have to fill this part out to show your math.

After calculating the taxes in Parts 3, 4, and the fixed dollar minimum, you compare them. You pay the highest.

Don't Forget the Schedules

The CT-3 is rarely the only form you file — it's usually the cover page for a stack of attachments. Depending on your situation, you might also need:

• Form CT-225: To report specific New York modifications to your income.
• Form CT-3.4: If you're carrying forward a net operating loss.
• Form CT-3-M: If your business is in the Metropolitan Commuter Transportation District (MCTD), you owe an extra surcharge — and this is a separate required return.

Common Mistakes

• Using Last Year's Form: The state changes these forms annually. If you file on a 2024 form for your 2025 taxes, they will reject it. It will be considered late, and you'll get hit with penalties and interest.
• Forgetting the MTA Surcharge: If you're in the MCTD, don't forget Form CT-3-M. It's a separate return, but it's required.
• Skipping Part 6: Even if your business is 100% in New York, you have to fill out the apportionment section. Leaving it blank is a red flag.
• Missing the Combined Filing Rules: If you have related corporations, you need to check if you're required to file on Form CT-3-A. Filing separately when you should have combined can lead to a big reassessment.

Frequently Asked Questions

What's the difference between the CT-3 and the CT-3-A?

The CT-3 is for a single corporation filing by itself. The CT-3-A is the combined return. You file the CT-3-A if you are part of a group of corporations that are unitary and meet the ownership thresholds (generally 80% or more ownership). The group files one return that combines all their income and capital.

My corporation is set up as an S Corp. Do I file CT-3?

No. If you elected to be treated as a New York S corporation (by filing Form CT-6), you file Form CT-3-S, the New York S Corporation Franchise Tax Return. The CT-3 is specifically for C corporations.

I dissolved my corporation this year. Do I still need to file?

Yes. You need to file a final return. On Part 1 of the CT-3, you'll check the box indicating this is a “final return.” For domestic corporations, remember: you are liable for taxes until you formally dissolve with the Department of State. You can't just stop filing because you stopped operating.
