Quick answers
Yonkers bookkeeping, in five questions.
- Who provides bookkeeping for Yonkers businesses?
TechBrot provides Certified QuickBooks ProAdvisor bookkeeping across Yonkers and lower Westchester — a named bookkeeper per file, working remotely on QuickBooks, with retail, healthcare, professional services, and trades.
- What is the Yonkers sales tax rate?
8.875% combined — 4% state + 4% Westchester County + 0.375% MCTD + a 0.5% Yonkers city tax. That’s the same as NYC and the highest rate in Westchester; most other Westchester cities are 8.375%.
- What does it cost?
$400–$2,500+/mo for monthly bookkeeping; $1,500–$15,000+ for one-time cleanup. Fixed-fee against a written scope, never hourly.
- Does Yonkers have the NYC business taxes?
No. Yonkers matches NYC’s 8.875% sales tax, but it’s in Westchester — not a NYC borough — so there’s no Unincorporated Business Tax and no Commercial Rent Tax. Just the sales tax plus standard state and federal taxes.
- Why is the Yonkers rate higher than the rest of Westchester?
Yonkers adds a 0.5% city sales tax on top of the 8.375% most of Westchester charges, bringing it to 8.875%. We track the correct rate in QuickBooks so your return reconciles.
Bookkeeping built for how Yonkers actually operates
Why Yonkers books have their own character.
Yonkers sits in an unusual spot — a Westchester city that charges New York City’s 8.875% sales tax but carries none of the city’s business taxes — and getting that distinction right is exactly where bookkeeping earns its keep.
As New York State’s fourth-largest city and the gateway between the Bronx and Westchester, Yonkers has a dense, diverse business base — retail and restaurants along South Broadway and Central Avenue, a large healthcare presence, professional-services firms, contractors and trades, and the commercial activity around the redeveloped waterfront and Ridge Hill. What makes its books distinctive is the tax position: Yonkers is the only Westchester city that matches NYC’s 8.875% combined rate — most of the county is 8.375% — because it layers a 0.5% city sales tax on top. Charge the wrong one and you’re either short-remitting or overcharging customers.
At the same time, Yonkers businesses get a real simplification that NYC businesses don’t: because the city is in Westchester rather than a borough, there is no Unincorporated Business Tax and no Commercial Rent Tax. A Yonkers business owner who assumes “effectively NYC rates” on the sales-tax side but worries about the UBT is half right and half wrong — and that’s exactly the kind of thing a bookkeeper who knows the jurisdiction keeps straight. When the 8.875% rate isn’t reconciled correctly, the quarterly return drifts; when an owner over-worries about city taxes that don’t apply, they waste money and attention.
The result: books that reflect how a Yonkers business actually operates — the right sales-tax rate, none of the NYC business taxes that don’t apply — reconciled every month and handed to your CPA CPA-ready, so filing the sales tax and income returns is fast and accurate.

The advisory line

For a Yonkers business, the value isn’t categorizing a transaction — it’s charging the right sales-tax rate, not over-worrying about NYC taxes that don’t apply, and knowing your real margins.

Common questions
Yonkers bookkeeping questions.
Yes. TechBrot provides Certified QuickBooks ProAdvisor bookkeeping for businesses across Yonkers and lower Westchester. Work is delivered remotely on QuickBooks Online or hosted Desktop, by a named bookkeeper on the same file every month — with fluency in the Yonkers tax position, including the 8.875% rate and the absence of NYC business taxes, that a generic bookkeeper often gets wrong.
Yonkers’ combined sales tax is 8.875% — 4% New York State, 4% Westchester County, 0.375% MCTD, and a 0.5% Yonkers city tax. That matches New York City’s rate and is the highest in Westchester; most other Westchester municipalities are 8.375%. New York is destination-based, so you charge the rate where your customer takes delivery, and you file one NYS Web File return. We track the correct rate in QuickBooks so your quarterly return reconciles.
No — and this is the key Yonkers distinction. Even though Yonkers matches NYC’s 8.875% sales-tax rate, it is a Westchester city, not a NYC borough, so the Unincorporated Business Tax (UBT) and Commercial Rent Tax (CRT) — both NYC-only — do not apply. A Yonkers business deals with the 8.875% sales tax plus standard New York State and federal income taxes, with no separate city-level business tax.
Yonkers adds a 0.5% municipal sales tax on top of the 8.375% rate that applies across most of Westchester County (4% state + 4% county + 0.375% MCTD), bringing the Yonkers total to 8.875%. It’s a small difference that’s easy to get wrong — charging 8.375% in Yonkers means short-remitting, while charging 8.875% elsewhere in Westchester means overcharging customers. We make sure the right rate is applied and reconciled.
TechBrot quotes fixed monthly fees against a written scope — not hourly. Ongoing monthly bookkeeping runs $400–$2,500+/mo depending on transaction volume and accounts; one-time cleanup runs $1,500–$15,000+. We scope transparently before any work begins, so there are no surprises.
Yes — it’s one of the most common engagements. Yonkers businesses fall behind in their books for the usual reasons — growth, turnover, wearing too many hats. We scope a one-time cleanup or catch-up to a CPA-ready standard, then move into monthly bookkeeping so the file stays clean.
Yes — those are core Yonkers verticals, alongside professional services and nonprofits. Each has specific needs: contractors need job costing, healthcare practices need insurance-receipt and payroll reconciliation, and retailers need deposits reconciled against the correct 8.875% rate. See our New York industry pages for the detail.
