By: Jeremy Hinckley, CPA, VP of Accounting & Compliance
The new year is when many early-stage companies discover how quickly accounting, tax, and compliance requirements can escalate in priority—especially in research-driven and federally funded environments. Here are some key dates to keep in mind for organizations with a December 31st fiscal year-end. Early planning for these deadlines can help avoid surprises and ensure smoother operations as the year gets underway.
Key Dates and Considerations:
- March 15 – S corporations and partnerships must file their federal tax returns or request an extension, with estimated taxes due as applicable.
- April 15 – C corporations and individuals must file their federal tax returns or request an extension, with estimated taxes due as applicable.
- April 30 – NIH-funded institutions must submit revised research misconduct-assurance policies to the Office of Research Integrity (ORI)
- September 30 – Single audit due; required when an organization expends $1 million or more in federal awards during its fiscal year
- Various early-year dates – State and local annual reports, franchise taxes, and registrations
