SB SL Tax Code: NY Small Business Eligibility and CT-3 Filing

To file as a New York small business taxpayer under Article 9-A, a corporation must meet four requirements at the same time — entire net income of $390,000 or less, paid-in capital of $1 million or less, an average of 100 or fewer full-time New York employees, and no membership in a disqualifying affiliated group — and then report the qualifying figures on Form CT-3, which applies a 0% rate to the capital base. There is no separate election or checkbox. The numbers on the return are what trigger the status, so the New York small business taxpayer filing requirements are really about proving each of the four tests and getting the figures onto the right lines by the deadline.

The Four Eligibility Tests

New York Tax Law Section 210(1)(f) sets four tests, and missing one disqualifies the corporation for that tax year.¹

Entire Net Income of $390,000 or Less

Entire net income for the tax year cannot exceed $390,000. If the tax year is shorter than 12 months, the state annualizes: multiply the income by 12 and divide by the number of months in the period.¹

Paid-In Capital of $1 Million or Less

Total paid-in capital is the aggregate money and other property the corporation has received for stock, as capital contributions, and as paid-in surplus. It is not total assets and not capital in use. For non-cash property, the amount counted is the corporation’s adjusted basis at the time of receipt, reduced by any liabilities assumed.¹

100 or Fewer Average Full-Time New York Employees

Count full-time employees in New York (excluding general executive officers) on March 31, June 30, September 30, and December 31, then average the four numbers. Full-time means 35 or more hours per week, and two part-time positions can combine to equal one full-time equivalent.¹

Not Part of a Disqualifying Affiliated Group

The corporation cannot be part of an affiliated group as defined under IRC Section 1504, unless the entire affiliated group would independently meet all of the small business criteria if it had filed a combined New York return.¹ This is where many corporations lose the status. If your company is a subsidiary or belongs to a group of related corporations that together exceed the income, capital, or employee thresholds, small business status is unavailable, even if your individual entity is tiny.

What Qualifying Actually Saves You

For tax years beginning on or after January 1, 2021, small business taxpayers pay 0% on the capital base.¹ The standard rate is 0.1875% of New York-apportioned business capital. On $1 million of apportioned capital, that is $1,875 gone — reduced to zero with small business status.

Small business taxpayers also get an exemption from the capital base computation entirely during their first two taxable years.¹

Because franchise tax equals the highest of the three bases (business income, capital, or fixed dollar minimum), zeroing out the capital base means most qualifying small corporations end up paying either 6.5% on business income or the fixed dollar minimum. That minimum starts at $25 for corporations with New York receipts of $100,000 or less, $75 for receipts up to $250,000, $175 up to $500,000, and $500 up to $1 million.²

One boundary worth naming: qualifying does not exempt you from the MTA surcharge if your corporation has activity in the Metropolitan Transportation Authority region. The surcharge equals 30% of the franchise tax apportioned to that region and applies on top of whatever base produces your tax, including the fixed dollar minimum.

Documentation to Pull Together Before You File

Each of the four tests has to be provable from your own records, so gather these before starting the return:

The completed federal Form 1120 or 1120-S. New York’s modifications layer on top of federal taxable income, so the federal return has to be finished first.
Paid-in capital records covering every stock issuance, capital contribution, and paid-in surplus entry since formation. For property contributed in exchange for stock, keep the adjusted basis at the date of contribution and the amount of any liabilities the corporation assumed.¹
Employee headcount on March 31, June 30, September 30, and December 31, excluding general executive officers.¹
Asset and liability schedules showing business capital apportioned to New York versus other jurisdictions. You still complete the capital base computation even when the rate is 0%.
Ownership percentages and any parent-subsidiary or brother-sister relationships that could pull you into an affiliated group.

Claiming Small Business Status on Form CT-3

General business corporations subject to Article 9-A file Form CT-3.² Combined groups use Form CT-3-A instead.³

Enter entire net income on Part 3, line 7. If the amount is $390,000 or less and the other three tests are met, the form’s calculations apply the reduced capital base rate. There is no single checkbox for small business status. The designation flows from the reported numbers, which is why the income, paid-in capital, and employee figures have to be right.

If the corporation has investment income or investment capital, attach Form CT-3.1 (Investment and Other Exempt Income and Investment Capital). The attachment is required whenever there are entries on the CT-3 lines tied to exempt income or investment capital.⁴

Deadlines, Extensions, and Estimated Tax

Calendar-year corporations file Form CT-3 by March 15. Fiscal-year filers have until the 15th day of the third month after their year ends. Corporations using tax software to prepare their own returns, and preparers filing on behalf of clients, must e-file.⁵

Form CT-5 grants a six-month extension to file, but only if you submit it and pay properly estimated tax by the original due date. Properly estimated means the payment either equals or exceeds last year’s franchise tax (from a 12-month year) or covers at least 90% of the current year’s final liability. Form CT-5.1 can request two additional three-month extensions if six months is not enough.⁶

C corporations under Article 9-A must make quarterly estimated tax payments if expected franchise tax for the year exceeds $5,000. S corporations under Article 9-A are not required to make estimated payments.⁷ For most qualifying small business taxpayers, the $5,000 threshold sits well above what they owe, so estimated payments are usually not required.

Penalties for a Bad Claim

If reported tax falls short of the correct amount by more than 10% or $2,000, whichever is greater, New York charges a penalty of 10% of the shortfall. Late filing adds a separate penalty of 0.5% of the unpaid tax per month, up to 25%.⁸

Because the small business designation changes the capital base rate from 0.1875% to 0%, an inaccurate claim underpays that base by a visible amount. Returns with reported income sitting just under the $390,000 line, or with paid-in capital pushed just under $1 million, are the kind the state’s systems flag.

How Long to Keep the Records

New York requires corporations to retain records for as long as they may be material to the administration of Article 9-A. The IRS provides more specific benchmarks: at least three years from the filing date in most situations, six years if you omit more than 25% of gross income, and seven years if you claim a loss from worthless securities or bad debts. Employment tax records go at least four years. If you never file a return or file a fraudulent one, there is no expiration.⁹

For the small business taxpayer test specifically, keep the quarterly employee counts, paid-in capital documentation, and affiliated group analysis for at least as long as the statute of limitations remains open on the year they support. If the state ever asks whether you legitimately qualified, those are the records that answer.
