Manhattan bookkeeping — the only borough with three NYC taxes to track.

TechBrot delivers Certified QuickBooks ProAdvisor bookkeeping for Manhattan businesses — monthly bookkeeping, cleanup, and QuickBooks management by a named bookkeeper on the same file every month. Manhattan (New York County) carries all three NYC business taxes: the 8.875% combined sales tax, the 4% Unincorporated Business Tax (for unincorporated businesses, after a $95,000 gross-income threshold), and — uniquely — the Commercial Rent Tax, which applies only to commercial tenants in Manhattan south of 96th Street (an effective ~3.9% on base rent at $250,000+ a year, with a full small-business credit below $5M income and $500K rent). The other four boroughs don’t owe CRT; Manhattan does. We keep your books CPA-ready and coordinate with your CPA, who files. Fixed-fee against a written scope — $400–$2,500+/mo monthly; cleanup $1,500–$15,000+. Delivered remotely on QuickBooks Online or hosted Desktop. Independent firm — not affiliated with Intuit Inc.; does not file NY/NYC taxes.

Manhattan shares the citywide sales tax and UBT with the other boroughs — but it’s the one borough still inside the Commercial Rent Tax zone, and that single fact changes how a Manhattan business’s books have to be kept.

Manhattan is the densest commercial market in the country — finance and professional services, a deep tech and startup base, media and advertising, hospitality, retail, and medical practices, stacked into the highest commercial rents in the city. Most of that activity happens south of 96th Street, which is precisely the zone where the Commercial Rent Tax still applies. So on top of the 8.875% sales tax and the 4% UBT that every borough deals with, a Manhattan tenant paying serious rent has a third NYC tax in play — one that’s assessed on base rent, owed regardless of whether the business turned a profit, and easy to overlook until a notice arrives.

That third layer is exactly what generic, software-only bookkeeping misses. A tech startup that just signed a Midtown lease after a raise can cross the CRT threshold without realizing it. A growing professional-services firm needs base rent tracked cleanly so its CPA can claim the right credit instead of overpaying. An agency billing media buys needs ASC 606 gross-vs-net treatment right, or revenue is off by multiples. A retailer needs deposits reconciled against the 8.875% rate at the same time. And every unincorporated Manhattan business still has the UBT to structure for. TechBrot keeps a named bookkeeper on your file who knows a Manhattan business carries one more tax than a business across the river in Brooklyn.

The result: books that reflect how a Manhattan business actually operates — sales tax, UBT, and the base-rent records the CRT turns on — reconciled every month and handed to your CPA CPA-ready, so every NYC filing is fast, accurate, and claims every credit you’re owed.

Software can import a transaction, but it can’t tell you a new Midtown lease just pushed you over the Commercial Rent Tax threshold, that a credit could wipe out the bill, or that your UBT exposure is climbing. In the most expensive commercial market in the country, that judgment is the difference between overpaying NYC taxes and claiming every credit you’re owed — and it’s what a fractional-CFO engagement extends once your books are clean.
