Expert tax planning, R&D credits, and financial services for venture-backed startups in Manhattan, Brooklyn, and the NYC metro area, delivered remotely. Navigate New York's complex multi-layer tax system with confidence.
Why New York City Startups Choose SpryTax
New York has one of the most complex tax environments in the country. Federal, state, city, and unincorporated business taxes all apply. We specialize in helping NYC tech startups navigate this maze while maximizing tax savings.
New York R&D Tax Credits
New York has no general R&D credit, but companies admitted to the Excelsior Jobs Program can earn a refundable Excelsior R&D credit (50% of the federal credit for NY research, capped at 6% of NY research expenses). The federal credit is available to all qualifying startups.
- Excelsior R&D credit (refundable, by application)
- Federal payroll tax offset (up to $500K/yr)
- Life sciences R&D credit for eligible companies
NYC Unincorporated Business Tax
Navigate NYC's 4% Unincorporated Business Tax (UBT) for LLCs and partnerships, and the 8.85% Business Corporation Tax for most C-Corps. We help structure your entity to minimize exposure legally.
- UBT exemption analysis
- C-Corp vs LLC tax comparison
- Annual UBT return filing
Multi-State Tax Compliance
Many NYC startups have employees across NJ, CT, and beyond. We handle tri-state payroll taxes, nexus issues, sales tax on SaaS (New York taxes prewritten software, including SaaS), and apportionment for multi-state operations.
- NJ/CT employee tax compliance
- Convenience of employer rules
- Sales tax nexus management
VC & Growth Stage Support
NYC has become a major VC hub. We provide investor-ready financials, cap table management, and CFO services that meet the expectations of top NYC and national VCs.
- Monthly GAAP financials
- Fundraising financial models
- Due diligence preparation
Delaware + NY Compliance
Like SF, most NYC startups incorporate in Delaware. We manage dual-state compliance, franchise taxes, and make sure you're properly registered in both states.
- DE franchise tax optimization
- NY foreign qualification
- Annual compliance calendar
Stock Options & QSBS Planning
New York follows the federal QSBS exclusion: up to $10M (or 10x basis) for stock issued before July 5, 2025, and up to $15M for stock issued after July 4, 2025. We provide 409A valuations and help your equity structure qualify.
- 409A valuations & ISO grants
- QSBS qualification planning
- Option exercise tax planning
New York City Tax Challenges We Solve
Triple-Layer Tax System
NYC startups face federal taxes, NY State taxes (6.5% corporate, 7.25% on business income over $5M, plus the MTA surcharge; personal rates up to 10.9%), and NYC-specific taxes including the 8.85% Business Corporation Tax, UBT, and commercial rent tax. It's overwhelming without expert guidance.
Our Solution:
- • Entity structure optimization (C-Corp vs LLC)
- • Tax credit stacking (federal + state)
- • Strategic income timing across jurisdictions
- • Exemption and deduction maximization
Tri-State Employee Complexity
Employees living in NJ or CT while working for NYC employers create complex withholding, resident-credit, and "convenience of the employer" issues. NY has no reciprocity agreements with NJ or CT.
Our Solution:
- • Multi-state payroll setup & withholding
- • Remote work tax policy guidance
- • Convenience of employer audit defense
- • Quarterly tax reconciliations
High Cost of Living Impact
NYC salaries tend to be higher than in many other markets. That increases your qualified R&D expenses but also your payroll tax burden, so optimization is crucial.
Our Solution:
- • Maximize R&D credits on high salaries
- • Tax-advantaged compensation strategies
- • Commuter benefit programs
- • Equity compensation tax planning
Fintech Regulatory Complexity
NYC is a fintech hub. Financial services startups face additional regulatory requirements, BitLicense obligations, and industry-specific tax considerations.
Our Solution:
- • Fintech-specific tax planning
- • Regulatory compliance coordination
- • Payment processing tax treatment
- • Cryptocurrency tax reporting

How We Help an NYC Fintech Startup
The Challenge:
A typical scenario: a small fintech startup in the Flatiron District is overwhelmed by NY/NJ/CT multi-state taxes, hasn't claimed R&D credits, and isn't sure whether UBT or the Business Corporation Tax applies. Its prior accountant didn't focus on startup or fintech issues.
Our Solution:
- R&D credit study for the federal credit, plus an Excelsior eligibility review
- Entity review to confirm UBT vs. Business Corporation Tax exposure
- Set up proper tri-state payroll compliance for NJ/CT employees
- Implemented investor-ready monthly financials
- Provided fintech regulatory tax guidance
Results:
Illustrative scenario based on common NYC startup situations, not a specific client. Actual results depend on each company's facts.

Frequently Asked Questions
What is NYC's Unincorporated Business Tax (UBT)?
The UBT is a 4% tax on the NYC business income of unincorporated businesses (LLCs taxed as partnerships, partnerships, sole proprietors). Businesses with gross income of $95,000 or less don't need to file, and a business tax credit eliminates or reduces smaller UBT liabilities. C-Corporations don't pay UBT; most pay the NYC Business Corporation Tax (8.85%) instead. We help determine your optimal structure.
How do NY R&D credits compare to California?
California offers a general, nonrefundable 15% research credit. New York has no general R&D credit; its main option is the Excelsior R&D credit, which is refundable but only available to companies approved for the Excelsior Jobs Program. Pre-revenue startups in either state can also use the federal payroll tax offset (up to $500K per year) for qualified small businesses.
What is the "convenience of the employer" rule?
NY taxes income earned by remote workers who live outside NY but work for NY employers. If an employee works from home in NJ for "convenience" rather than the employer's necessity, NY treats those days as NY workdays. This can create double-taxation risk and complex compliance issues we help navigate.
Does New York recognize QSBS?
Yes. Unlike California, New York follows the federal QSBS (Qualified Small Business Stock) exclusion. For stock issued after July 4, 2025, the cap is $15M (or 10x basis) with partial exclusions after three and four years; for earlier stock, it's $10M (or 10x basis) after five years. This makes proper QSBS planning even more valuable for NY-based startups.
Do I need to register my Delaware C-Corp in New York?
Yes, if you have a physical presence, employees, or conduct substantial business in NY, you must register as a foreign corporation with the NY Department of State. You'll then file both Delaware franchise tax and NY corporate tax returns annually.
