Best Accountants in New York City for the Unincorporated Business Tax in 2026
Sam's List Editorial | 2026-08-28
Most New York City freelancers meet the unincorporated business tax the same way. They have their first good year, they file, and a second bill shows up that nobody warned them about.
The UBT is a 4 percent New York City tax on net income from an unincorporated business. If you run a sole proprietorship, a partnership, or an LLC taxed as a partnership inside the five boroughs, it is aimed at you.
It is not a small-print item. It is a separate return, on top of federal and New York State.
Below are vetted Sam's List accountants who work with New York City businesses that hit it, plus what to check before you hire any of them.
How We Picked (Methodology)
We want you to be able to check our work, so the criteria are stated plainly.
- The pool. Every firm considered here is a vetted member of the Sam's List directory. Sam's List reviews credentials, confirms the firm is actively practicing, and monitors client reviews over time. Firms not listed on Sam's List were not evaluated, so this is a list of vetted members rather than a survey of every accountant in New York City.
- How firms are ordered. Firms are grouped by the kind of business they are built to serve. They are not ranked one through ten, and no score is assigned. Where a firm has a meaningful number of client reviews we cite the verified count as of the date noted.
- What money does and does not buy. Some firms listed on Sam's List pay for a listing. Payment does not buy placement in this article, does not affect whether a firm appears, and does not affect reviews. Sam's List takes no referral fee and no commission on any engagement.
- What this is not. A directory listing is not a quality guarantee and this article is not a prediction about your engagement. It narrows the field to firms worth a conversation.
Who Actually Has to File
The filing trigger is not the same for every entity, and it is not the same as the point where you owe money. Two different numbers.
| You are | Form | You generally file when |
|---|---|---|
| Sole proprietor with NYC business activity | NYC-202 | Gross business income is above $95,000 |
| Partnership or LLC taxed as a partnership | NYC-204 | Gross income is above $25,000 |
| S corporation or C corporation | Not UBT | A different NYC corporate tax applies instead |
Two things people get wrong here:
- Gross, not net. The filing threshold looks at gross income. A partnership with $300,000 in billings and $40,000 in profit still files.
- The partnership number is low. Twenty-five thousand dollars is a side project, not a business. Two friends splitting consulting work can cross it in a quarter.
Thresholds and forms change. Confirm the current year's instructions on the NYC Department of Finance site before you rely on any number in a blog post, including this one.
The Credit Phase-Out Is Where the Real Rate Hides
The UBT has a credit that wipes out the tax at the bottom of the range and disappears at the top of it.
Between $95,000 and $135,000 of UBT income, every extra dollar you earn costs you more than 4 percent.
Here is the shape of it:
- At $95,000 of UBT income, the credit covers the full gross tax and the net UBT is zero.
- From $95,000 to $135,000, the credit shrinks as income rises, so the effective marginal rate inside that band runs well above the headline 4 percent.
- Above $135,000, the credit is gone and the 4 percent applies to the whole amount.
That band is exactly where a lot of freelancers land in a good year. It is also why timing a December invoice, or a December equipment purchase, is a real conversation and not a gimmick.
Vetted Sam's List Accountants Based in New York City
Three Sam's List partner firms are headquartered in New York City. Each works with a different kind of business, so read them as three doors rather than a ranking.
Purewater Financial
Purewater Financial has been working with New York City businesses since 2020, across small business owners, venture-backed startups, real estate investors, and solopreneurs.
That spread matters for UBT work specifically. The tax follows the entity, not the industry, so a firm that sees sole proprietors and partnerships in the same week has usually already argued the allocation questions your situation raises.

Ursa Consultants is a New York firm built around venture-backed startups, and has been since 2018.
Startup founders in the city run into the UBT in a specific way. The company converts to a C corp and leaves UBT behind, but the founder's pre-incorporation consulting income, and any partnership interests they still hold, do not.

Bookkeeper 360
Bookkeeper 360 has operated in New York since 2012 and works with small business owners, startups, real estate investors, and solopreneurs.
It is the closest of the three to a full back office. If your UBT problem is really a bookkeeping problem, which it often is, that is the relevant difference.

What to Ask on the First Call
Five questions separate a firm that files UBT returns from a firm that plans around them.
- How many NYC-202 or NYC-204 returns did you file last season?
- Where do you land on the unincorporated business taxable income allocation when I have clients outside the city?
- If I am in the credit phase-out band, what would you change before December 31?
- Would an S corporation election help or hurt me here, and what does it cost to maintain?
- What is your fee for the city return, separately from federal and state?
If the answer to question three is a general answer rather than a specific one about your numbers, keep looking.
The Honest Caveat
Nobody can promise you a smaller UBT bill. The tax is a percentage of a number, and most of the levers on that number are business decisions you were going to make anyway.
What a good NYC accountant changes is the surprise, not the rate. You find out in October what the January bill looks like, and you get to decide something about it while there is still time.

Frequently Asked Questions
Do I owe NYC UBT if I work from home in Brooklyn for clients outside the city?
Probably yes, at least in part. The UBT reaches unincorporated business income allocated to New York City, and where you perform the work matters. Income allocation for a business with clients elsewhere is a real calculation, not a yes or no, and it is the single most common thing an NYC accountant will adjust on a self-prepared return.
Does forming an LLC get me out of the UBT?
No. A single-member LLC is treated as a sole proprietorship and a multi-member LLC is treated as a partnership, and both are unincorporated for UBT purposes. Electing S corporation or C corporation treatment moves you out of the UBT and into a different NYC tax, which is sometimes better and sometimes worse.
Can I get a credit on my New York State return for UBT I paid?
New York State allows a credit against personal income tax for a portion of UBT paid, subject to limits based on income. It rarely covers the whole amount. Treat it as a partial offset when you are budgeting rather than a wash.
When is the UBT return due?
For calendar-year filers it generally follows the federal deadline pattern, with extensions available. Because the payment and the extension are separate things, an extension to file is not an extension to pay. Check the current year's NYC Department of Finance instructions or ask your accountant for the exact date.
