Specialized Accounting for Nonprofits

Nonprofits don’t operate like for-profits—and their accounting shouldn’t either. We understand fund accounting, restricted vs. unrestricted net assets, grant tracking, and functional expense reporting. Our team helps your board, donors, and program leads see clear, reliable numbers that support decisions and strengthen trust.

Form 990 Preparation & State Filings


Your IRS Form 990 tells the story of your organization to regulators, funders, and the public. We prepare the appropriate version—990, 990-EZ, or 990-N—plus required schedules, and handle New York charitable filings and extensions. Expect careful review of governance disclosures, functional expenses, and program service accomplishments, with e-file and confirmations for your records.



We’ll also calendar due dates and coordinate with staff and board so information is timely, accurate, and consistent with your mission narrative.

Audit & Review Support Without the Stress


Whether you need a financial statement review or must prepare for an external audit (grantor or threshold-driven), we’ll get your books audit-ready—tie-outs, schedules, and documentation in order. We coordinate with your auditor, respond to PBC lists, and keep your team focused on day-to-day operations.

Practical Controls & Ongoing Guidance

Small teams still need strong guardrails. We advise on basic internal controls—segregation of duties, approvals, and documentation flows that fit a lean staff—plus simple policies for expenses, gifts, and grants. As needs evolve, we can add payroll, sales tax (if applicable), and budgeting support, all synced to clear board reporting. Serving organizations across Port Jefferson Station, St. James, and greater Suffolk County.
