Tax & Accounting

We can provide you with tax preparation services and with a part-time CFO to support and supplement your internal financial staff.

Tax Preparation

501 Commons offers tax preparation services for 990s, state returns, and city returns. We know you don’t want to spend time reading definitions and filling out forms, so our approach is to make it as simple and painless as possible. We make sure your Form 990 does a good job of telling your story to potential donors.

Part-Time CFO

We can also serve as a part-time Chief Financial Officer (CFO). 501 Commons staff who serve in these roles have formal training and experience in some combination of business or nonprofit management, nonprofit accounting, finance, and consulting.
In this role, we can provide oversight of any accounting/bookkeeping staff you have, attend and present financials at finance committee or board meetings, help you prepare and manage your annual budget, and provide guidance on key financial issues. CFO services can be highly tailored to the specific needs of your nonprofit.

How it Works

Contact Kerry Kozuki at if you need referral assistance.


501 Commons can provide affordable and high-quality tax and accounting services. As a nonprofit ourselves, we have a good understanding of what information you need to help the board understand your 990 and to how to describe your organization to funders who are looking at your 990.

We can also provide you with a very affordable "slice" of senior financial management with our Part-Time CFO service.
