Two audiences in every return.
We prepare Form 990 and 990-PF filings with full schedule completion, compensation disclosure review, and narrative program accomplishment drafting. Before filing, every return goes through a public-facing review that evaluates how it reads to the donors, journalists, and board members who will search it, not just whether it satisfies the IRS.

Why does Form 990 accuracy carry more weight than a typical tax return?
Form 990 is the annual information return the IRS requires from most tax-exempt organizations. Unlike a for-profit tax return, it is a public document. Donors, journalists, rating agencies, and prospective board members can search it on platforms like ProPublica’s Nonprofit Explorer and form judgments about the organization based on what they find. An error that would be a quiet correction on a for-profit return becomes a visible, permanent public record.
Late filing carries its own severe consequence. Three consecutive years of missed 990 filings triggers automatic revocation of tax-exempt status, a rule the IRS applies without discretion regardless of circumstance. Extension management and filing coordination are what stand between an organization and that outcome.
What does Form 990 preparation include?
Form 990 & tax compliance.
Complete preparation of Form 990 for tax-exempt organizations, including applicable schedules based on each organization’s activities and circumstances. These may include Schedule A for public charity status and public support, Schedule C for lobbying and political activities, Schedule J for compensation, and Schedule R for related organizations, among others. When applicable, we also prepare Form 990-T for unrelated business income and related state tax and informational filings based on the organization’s filing requirements and activities.
Form 990-PF for private foundations.
Private foundations file Form 990-PF rather than the standard 990. Preparation includes excise tax calculation on net investment income, minimum distribution tracking, and self-dealing transaction review. The obligations are distinct enough that 990-PF preparation is its own discipline.
Draft return review.
For organizations that prepare draft returns internally or through a prior preparer, we provide independent review and refinement before filing. The review covers schedule accuracy, narrative disclosure quality, governance question responses, and how the finished return will read to a public audience.
Public disclosure review.
A pre-filing review pass that reads the completed return the way a donor, journalist, or rating agency will. The mission and program accomplishment narrative, the Part VII compensation section, and the Part VI governance responses are each assessed for what they communicate about the organization.
Extension management & filing coordination.
We prepare and file extensions (Form 8868) proactively and coordinate the filing timeline around your organization’s established governance review process.

How do we prepare & file your return?
01
Document collection.
We gather financial statements, governance documentation, and compensation data, flagging gaps early rather than discovering them mid-preparation.
02
Draft preparation.
We prepare the complete return and all applicable schedules, with attention to narrative disclosures and public-facing presentation.
03
Client review.
We walk through the draft with your team, addressing questions while there is still time to revise.
04
Board review period.
We build time for governance review into the filing timeline. Form 990 Part VI asks whether the final return was provided to the organization’s governing body before filing and requires
disclosure of the organization’s review process, if any. Our timeline allows the organization adequate time to complete its established review process before the return is filed.
05
Filing.
We submit the completed, reviewed return electronically within the applicable deadline or extension window, and confirm acceptance.
Financial credibility is the entire point.
Every return Han Group prepares is a nonprofit return. The nuances that distinguish nonprofit 990 preparation from generalist tax work are baseline practice: how to present program accomplishments in a way that a donor finds credible, how to structure compensation disclosures to withstand public scrutiny, and how to answer governance questions in Part VI so the responses reflect actual practice rather than aspirational description.
A generalist firm preparing your 990 alongside corporate returns applies a compliance-only lens because public-facing credibility is not a factor on the rest of their client base’s filings. We apply that lens to every return because every return we prepare carries the same public-disclosure stakes.
