Our services
Accounting and tax services for businesses and individuals
From a single personal return to full books, payroll and year-round planning for a growing business. Most firms do one or the other. Doing both is what makes the advice worth anything.
Our process
How we work with you
Tax season is where most of the damage shows up and almost none of it can still be fixed. The decisions that move the number happen in March, in July, and at the moment you choose an entity type.
We look at last year
Two or three prior returns tell us what was missed, what was filed defensively, and whether the entity structure still fits.
We fix the books
Clean ledgers and real reconciliations, because planning off a bad trial balance is guessing with extra steps.
We plan before year end
Estimated payments, retirement and entity decisions, timed while they can still change the outcome.
We file and stay reachable
Returns prepared and filed, and someone who answers in August when a notice turns up.

Common questions
Frequently asked questions
Do I have to come into an office?
No. We have offices in Brooklyn, Riverdale and Sag Harbor if you would rather sit down with someone, and plenty of clients never come in at all. Documents, signatures and meetings all work remotely.
Can you take over partway through the year?
Yes, and it is usually the better time. Moving in September leaves room to fix the books and act on what we find before year end. Moving in March means we file what already happened.
I am self employed in the city. What do I actually owe beyond federal and state?
As a New York City resident you file city resident income tax on your IT-201. If you run an unincorporated business in the city, the Unincorporated Business Tax can also apply at 4%, though the filing threshold is gross business income above $95,000 and a credit wipes out the tax entirely when it comes to $3,400 or less. Rental property on its own does not create UBT.
There is also the Metropolitan Commuter Transportation Mobility Tax. The self-employment threshold rises from $50,000 for 2025 and earlier to $150,000 for 2026 onward, which takes a lot of people out of it. More on how these fit together.
Do you prepare returns for more than one state?
Yes. Multi-state returns are routine here, which matters in this area more than most. Plenty of our clients live in Westchester and work in Manhattan, or live in New York and own property elsewhere.
What do you need from me to get started?
The last two or three years of returns and access to your books, if you keep any. That is enough for a first conversation about whether anything was left on the table.
