Do Maryland Nonprofits Need to Worry About Taxes?

If you run a nonprofit in Maryland, May often brings a big question: “We’re tax‑exempt, so do we really need to think about taxes right now?” For many organizations, the answer is yes, especially around federal Form 990 deadlines and Maryland compliance filings that cluster in the spring.

Below are a few key issues nonprofit boards and executive directors should keep on their radar each May:

1. Form 990 and “we don’t pay taxes” myths

Most tax‑exempt nonprofits must file an annual information return with the IRS (i.e Form 990, 990‑EZ, or 990‑N) by the 15th day of the 5th month after their year‑end, which for calendar‑year organizations is May 15. This return reports your mission, programs, revenue, expenses, and key governance details, even if you owe no income tax.

Many leaders assume “we’re a nonprofit, so we don’t deal with taxes,” but that’s not accurate. You may be exempt from federal income tax on your charitable activities, yet you still have filing obligations, and late or missed 990s can lead to penalties or even loss of exemption.

Aventa Tax routinely helps local organizations in Germantown and Rockville gather their financial records, prepare the appropriate Form 990, and align the numbers with their bookkeeping so Maryland non-profit tax preparation and financial reporting stay in sync all year.

2. Unrelated Business Income (UBI) and Form 990‑T

Even tax‑exempt organizations can owe income tax on “unrelated business income” (UBI)—money from activities that look more like a regular business and are not substantially related to your mission.

If your nonprofit has more than 1,000 dollars of gross unrelated business income, you may need to file Form 990‑T and pay unrelated business income tax.

This is an area where a small business accountant in Germantown Maryland, like Aventa Tax, can be especially helpful. A tax professional with expertise in Maryland non-profits can help determine if there is UBI and avoid surprise tax bills.

3. Maryland‑specific filings and payroll obligations

Beyond federal forms, Maryland nonprofits must stay current with state charity registrations, annual reports, and, if they have employees, payroll tax filings. While the exact due dates can vary, many organizations review their compliance calendar in May because it sits close to both federal tax season and common year‑end dates.

If your nonprofit operates a small side business—such as a café, thrift shop, or training program—you may face Maryland business tax rules similar to any other small entity, including sales and use tax or local business personal property filings, depending on what you sell and own. Aventa Tax offers business tax services in Montgomery County Maryland and surrounding areas that cover both traditional small businesses and nonprofits with earned‑income activities, so your whole organization stays compliant under one roof.

4. When to bring in a professional

You can often handle basic record‑keeping in house, but you should contact a professional when:

You are unsure whether an activity creates unrelated business income.

Your nonprofit is growing quickly and adding staff, programs, or locations.

You’ve missed a filing deadline or received an IRS or Maryland notice.

Aventa Tax supports nonprofits with year‑round business tax preparation and planning, bookkeeping in QuickBooks or Xero, and help responding to IRS or state letters so you can stay focused on your mission instead of decoding tax rules.
