NYC UBT Allocation Factor Calculator — Free & Instant BAP Tool

Last updated: July 13, 2026. Tax rates, filing thresholds, and allocation weightings reflect current NYC law and may change — always verify with the NYC Department of Finance.

How the NYC UBT Allocation Factor Works

The NYC Unincorporated Business Tax (UBT) applies only to income that is "allocable" to New York City. The allocation factor, also called the Business Allocation Percentage (BAP), is the percentage of your worldwide business income that NYC can tax. You calculate it by comparing your New York City presence—measured by property, payroll, and receipts—to your total presence everywhere.

The BAP is not a choice. It is a mathematical formula prescribed by the NYC Administrative Code. Most businesses use the three-factor formula, which averages three separate ratios. Since 2015, service-based businesses generally use the single sales factor (receipts only). Manufacturers can elect to double‑weight the receipts factor.

The Three Factors Explained

Once you have these three percentages, you apply the weightings for your tax year. For example, in 2010, the weights were 27% for property, 27% for payroll, and 46% for receipts. Since 2015, the single sales factor uses 100% for receipts and 0% for property and payroll—meaning your BAP equals your receipts factor alone.

Missing factors: If you have no property or no payroll in NYC, those factors are omitted, and the remaining weights are re‑proportioned to total 100%. For example, if you have no NYC property, the payroll and receipts weights are increased proportionally so they sum to 1.

Manufacturing double‑weighting: Qualified manufacturers can elect to count the receipts factor twice before averaging. This election can lower your BAP if your receipts factor is lower than your property and payroll factors. Use the calculator above to see the effect.

Step‑by‑Step Walkthrough to Use This Calculator

Using the calculator is straightforward. Follow these steps to get your Business Allocation Percentage (BAP) and estimated UBT.

1. Select your tax year. Choose the year you are filing for. The calculator automatically applies the correct weightings (three‑factor or single sales) based on your selection.
2. Choose your allocation method. The default is Three‑Factor Formula. If you are a service business and your tax year is 2015 or later, select Single Sales Factor. Only use Books & Records if you have prior NYC DOF consent.
3. Enter your property numbers (if using three‑factor). Include owned real estate, rented real estate (annual rent × 8), and tangible personal property. Enter NYC amounts and total worldwide amounts.
4. Enter your payroll numbers (if using three‑factor). Include all compensation for services performed in NYC. Do not include payments to independent contractors (1099).
5. Enter your receipts numbers (required for all methods). Use gross income from services performed in NYC (market‑based sourcing) plus sales delivered to NYC addresses.
6. Optionally, enter your taxable income after the $5,000 statutory exemption. The calculator will estimate your NYC UBT based on your BAP.
7. If you are a manufacturer, check the box to elect double‑weighted receipts. This option only appears when Three‑Factor is selected.
8. Click "Calculate My BAP". The results panel will show your BAP, a breakdown of each factor, and your estimated UBT (if you entered taxable income).

Pro tip: Compare results across methods. If you are unsure which method applies, try both Three‑Factor and Single Sales Factor (if your tax year allows) to see which gives a lower BAP—but always confirm with a tax professional which method you are legally required to use.

What if I have no employees? If you have no payroll in NYC or anywhere, the payroll factor is omitted, and the weights are re‑proportioned. The calculator handles this automatically. The same applies if you have no property.

What if I work from home part‑time? For receipts, NYC uses market‑based sourcing—income from NYC clients counts as NYC receipts regardless of where you work. For payroll, allocate based on days worked in NYC. This calculator does not automatically apportion payroll by days worked; you must enter your NYC payroll amount based on actual work location.

Tax Year Weighting Guide

The weights applied to property, payroll, and receipts have changed over time. Using the wrong weightings for your tax year is one of the most common errors taxpayers make. The table below shows the official weightings for each period.

Sources & accuracy: Allocation weightings, filing thresholds, and the UBT rate reflect NYC law as of 2026 and are subject to change. Verify current figures with the NYC Department of Finance — Unincorporated Business Tax.

Which method applies to you? If your tax year is 2015 or later and you provide services, you must use the single sales factor unless you elect otherwise with the NYC Department of Finance. Manufacturers and businesses with significant property or payroll may still use the three‑factor formula, but the default is single sales for most taxpayers.

The calculator above automatically applies the correct weightings based on your selected tax year. If you select a tax year prior to 2015, it uses the three‑factor formula with the corresponding weights. For 2015+, the default is single sales factor, but you can manually switch to three‑factor if your situation allows.

Important Caveats When Calculating

The allocation factor formula appears straightforward, but several nuances can trip you up. Understanding these caveats helps you avoid errors and potential audit triggers.

1. Missing Factors

If you have no payroll or no property in NYC (or anywhere), that factor is omitted from the calculation. The remaining factors are re‑proportioned to total 100%. For example, if you have no NYC property and no total property, the property factor is dropped, and the payroll and receipts weights are adjusted upward proportionally. The calculator handles this automatically and will show a warning when a missing factor is detected.

2. Market‑Based Sourcing for Receipts

NYC uses market‑based sourcing for service revenue. This means receipts from services are sourced to NYC if the service is delivered to or received by a customer located in NYC—regardless of where you physically perform the work. For example, if you are a consultant based in New Jersey but 80% of your clients are in NYC, 80% of your receipts count as NYC receipts. This is a common source of confusion, especially for remote workers.

3. Payroll Allocation for Remote Workers

Payroll is allocated based on where services are performed. If an employee works 3 days in NYC and 2 days elsewhere, only 60% of their compensation counts as NYC payroll. For owners and partners, the same rule applies—allocated based on days worked in NYC. You must track actual work locations to support your payroll factor.

4. Manufacturing Double‑Weighting Election

Qualified manufacturers can elect to double‑weight the receipts factor. This means you count receipts twice before averaging with property and payroll. The formula becomes: (Property Factor + Payroll Factor + 2 × Receipts Factor) ÷ 4 (or with adjusted weights). This election can lower your BAP if your receipts factor is lower than your other factors. You must make this election on your return; it is not automatic.

5. Books & Records Method — Prior Consent Required

You may use the books and records method only if you maintain separate books that clearly identify NYC income and expenses. This method is not a simple alternative—you must obtain prior written consent from the NYC Department of Finance. Without that consent, you must use the formula method. The calculator includes the books and records option, but use it only if you already have approval.

6. Incorrect Factor Data = Audit Risk

The NYC Department of Finance audits allocation factors regularly. If your factor appears unusually low compared to similar businesses, you may receive an inquiry. Ensure you have documentation for every number you enter—lease agreements, payroll records, revenue reports—to substantiate your allocation. Keep these records for at least 3 years after filing.

7. 1099 Contractors Are Not Payroll

Payments to independent contractors (reported on Form 1099) are not included in the payroll factor. Only W‑2 employee compensation counts. This is a common mistake—do not add 1099 payments to your payroll numbers. If you personally receive 1099-MISC income rather than pay it, you may also need to determine whether it owes federal self-employment tax—our 1099-MISC Box 3 Self-Employment Tax Exemption Checker can help you decide.

8. Part‑Year Businesses

If your business started or ceased operations during the tax year, you must annualize your property, payroll, and receipts. The formula uses averages; for a partial year, you may need to pro‑rate amounts to reflect the period of activity. The calculator assumes full‑year data; adjust your inputs accordingly.

When in doubt, consult a CPA. The allocation factor has significant tax implications, and errors can be costly. Use this calculator as a planning tool, but always verify your final numbers with a tax professional.

Single Sales Factor Method Explained

Since 2015, New York City has required most service‑based businesses to use the single sales factor method for UBT allocation. Under this approach, only the receipts factor matters—property and payroll are completely ignored. The formula becomes:

The single sales factor favors businesses with high payroll or property outside NYC but significant NYC revenue. For example, a consulting firm with 50% of its payroll in NYC but 40% of its revenue from NYC clients would have a 40% BAP under the single sales factor—lower than the three‑factor result in many cases.

Who must use the single sales factor? Service businesses (including professional services, consulting, technology, and financial services) with tax years beginning on or after January 1, 2015. Manufacturers and businesses that sell tangible goods may still use the three‑factor formula, though they can elect single sales if it produces a lower BAP.

Can you opt out? Yes—businesses can elect to use the three‑factor formula instead of single sales, but only with prior consent from the NYC Department of Finance. The election must be made on the return and applies to all subsequent years unless revoked. Most taxpayers find the single sales factor simpler and more favorable.

The calculator above defaults to the single sales factor for tax years 2015 and later. You can manually select the three‑factor formula if your business qualifies for an election.

How to Reduce Your UBT Allocation Percentage Legally

Your allocation factor directly affects your NYC UBT liability. A lower BAP means less of your income is subject to the 4% UBT rate. While you cannot manipulate the formula, you can structure your business operations to legally minimize your allocation—provided you follow the rules.

1. Choose the Right Allocation Method

If your tax year and business type allow, compare the single sales factor against the three‑factor formula. Service businesses with significant out‑of‑state clients and high NYC payroll often benefit from the single sales factor. The calculator lets you compare both methods instantly.

2. Reduce NYC Payroll Through Remote Work

Payroll is allocated based on where services are performed. If you allow employees to work from outside NYC, a portion of their compensation shifts out of the NYC payroll factor. This reduces your BAP under the three‑factor formula. Track work locations carefully and document the days worked in NYC vs. outside.

3. Evaluate Manufacturing Double‑Weighting

If you are a qualified manufacturer, electing double‑weighted receipts can lower your BAP if your receipts factor is lower than your property and payroll factors. Run the numbers both ways—with and without the election—to see which gives the better result.

4. Review Your Property Factor

Rented property is valued at 8× annual rent. If you lease expensive NYC office space, your property factor may be disproportionately high. Consider whether a smaller NYC footprint—or moving to a less expensive location—could reduce your property factor without harming your business.

5. Verify Your Receipts Sourcing

NYC uses market‑based sourcing for receipts. If you are sourcing receipts incorrectly—for example, counting revenue from out‑of‑state clients as NYC receipts—you may be overpaying. Review your client locations and ensure you are only counting receipts from NYC‑based customers (for services) or deliveries to NYC addresses (for goods).

6. Consider Books & Records (with Caution)

If your business has unique circumstances that make the formula unreasonable, you may apply for the books and records method. This requires prior DOF consent and detailed separate accounting, but it can produce a more accurate—and potentially lower—BAP.

Important: All reductions must be supported by documentation. The NYC Department of Finance scrutinizes allocation factors that are unusually low. Maintain thorough records of employee work locations, client addresses, lease agreements, and revenue sources. Consult a CPA before implementing any strategy.

Common Allocation Mistakes to Avoid

The NYC UBT allocation factor is one of the most common places taxpayers make errors. These mistakes can lead to underpayment, penalties, and audit triggers. Here are the most frequent pitfalls and how to avoid them.

Mistake 1: Using the Wrong Weightings

Using 2010 weightings (27/27/46) for a 2024 tax year—or vice versa—is a common error. The weightings have changed multiple times, and using the wrong ones produces an incorrect BAP. Always select the correct tax year in the calculator.

Mistake 2: Including 1099 Payments in Payroll

Payments to independent contractors (1099‑NEC or 1099‑MISC) do not belong in the payroll factor. Only W‑2 employee compensation counts. Including 1099 amounts inflates your NYC and total payroll—and your BAP.

Mistake 3: Sourcing Receipts Incorrectly

For service businesses, receipts are sourced to where the customer is located (market‑based sourcing)—not where the service is performed. If you perform work from New Jersey for a NYC client, that revenue still counts as NYC receipts. Many remote workers get this wrong.

Mistake 4: Forgetting Rented Property × 8

Rented property is valued at 8 times the annual rent for the property factor. Using the actual rent amount (without the multiplier) understates your property factor and your BAP. This is a common and costly error.

Mistake 5: Ignoring Missing Factor Rules

When a factor is missing (e.g., no NYC property), the remaining factors are re‑proportioned to total 100%. Some taxpayers incorrectly average the remaining factors equally without adjusting the weights. The calculator handles this automatically—pay attention to the warning it shows.

Mistake 6: Not Documenting Your Allocation

The NYC Department of Finance may request documentation to support your factor. If you cannot produce lease agreements, payroll records, and revenue reports that match your allocation, you face audit risk. Keep organized records for at least 3 years.

Mistake 7: Using the Wrong Form

Individuals and sole proprietors use Form NYC‑202 (Schedule B). Partnerships use Form NYC‑204 (Schedule C). Using the wrong form leads to incorrect filing and potential rejection. The allocation factor calculation is the same, but the form structure differs. If your partnership is weighing the NYS PTET election, our NYS PTET Electing vs Non-Electing Partner Allocation Calculator shows the dollar impact for each partner.

Mistake 8: Assuming the Calculator Is a Substitute for Professional Advice

This tool provides estimates and planning support. Your final allocation factor must be reviewed by a qualified tax professional familiar with your specific situation. Use the calculator to guide your conversation with your CPA, not to replace it.

Bottom line: Small errors in your allocation factor can mean significant tax differences. Double‑check your inputs, document everything, and consult a professional before filing.

Why This Calculator Is Different: Real‑World Scenarios & Audit Defense

Most NYC UBT resources give you the formula and leave you to figure out the rest. This calculator and guide are different. We focus on the scenarios that actually matter to business owners—remote work, method comparison, and how to justify your numbers if the NYC Department of Finance comes calling.

The Remote Work Impact: A Real‑World Example

Post‑pandemic, many businesses operate with a hybrid workforce. This affects your allocation factor significantly. Consider this example:

• A professional services firm with 10 employees: Each employee works 2 days per week in NYC (40% of the time) and 3 days remote (60% of the time).
• Total payroll: $2,000,000.
• If all employees were in NYC full‑time: NYC payroll = $2,000,000 (100% allocation).
• With hybrid work (40% in NYC): NYC payroll = $800,000 (40% allocation).

Using the three‑factor formula with equal property and receipts across the board, the BAP drops from roughly 60% to roughly 40%—a tax saving of up to $8,000 per $100,000 of taxable income. This is why tracking work location matters.

The calculator lets you adjust your NYC payroll input to reflect actual days worked in NYC. Enter your payroll based on documented work location—not where employees are "based."

Method Comparison: Which One Saves You More?

The table below shows how different methods affect the BAP for a sample business with:

• Property: 30% NYC / 70% outside
• Payroll: 60% NYC / 40% outside
• Receipts: 40% NYC / 60% outside

Note: Figures assume property 30% NYC, payroll 60% NYC, and receipts 40% NYC. The manufacturing double‑weighted result (42.5%) is calculated as (0.30 + 0.60 + 2 × 0.40) ÷ 4. Run your own numbers in the calculator for your situation.

Audit Defense: How to Justify Your Allocation

If the NYC Department of Finance audits your UBT return, they will scrutinize your allocation factor. Here is what they look for—and how to defend your numbers:

1. Property factor: Have you used the correct valuation for rented property (8× annual rent)? Do you have lease agreements that support your NYC property numbers? Keep copies of all leases and property tax records.
2. Payroll factor: Do you have payroll records that clearly show which employees worked in NYC and for how many days? Time sheets, work location logs, and payroll summaries are critical. The DOF expects detailed documentation.
3. Receipts factor: Do you have invoices, contracts, or delivery records that show where services were received or goods were delivered? For service businesses, customer location determines sourcing. Maintain a customer address database.
4. Missing factors: If you omitted a factor, be prepared to explain why (e.g., "No property in NYC"). The DOF will verify that the omission is valid.
5. Books and records method: If you use this method, you must have prior DOF consent and separate books that clearly identify NYC income and expenses. Without both, you cannot use this method.

Pro tip: Keep a "tax file" with all allocation documentation organized by factor. Include a written memo explaining your methodology. If the DOF contacts you, you will have everything ready—saving you stress and potential penalties.

Missing Factor Handling: A Clear Example

Missing factor rules confuse many taxpayers. Here is a concrete example:

• You have: NYC payroll = $100,000, total payroll = $200,000 → payroll factor = 50%.
• You have: NYC receipts = $50,000, total receipts = $100,000 → receipts factor = 50%.
• You have: No property anywhere → property factor is omitted.
• Your tax year is 2010: The standard weights are 27% property, 27% payroll, 46% receipts. Since property is missing, you re‑proportion the remaining weights: payroll weight = 27/(27+46) = 37%; receipts weight = 46/(27+46) = 63%.
• Your BAP = (50% × 37%) + (50% × 63%) = 18.5% + 31.5% = 50%.

The calculator does this automatically. If you see a "Missing Factor Warning," check your inputs—the result has been adjusted accordingly.
