Key Insight

Quick Answer

Tax-exempt doesn't mean compliance-exempt. Nonprofits still file Form 990 (public, and mandatory once gross receipts pass $50,000), owe UBIT once unrelated business income tops $1,000, and lose exempt status automatically after three consecutive missed filings. Taxstra handles the 990, UBIT exposure, and state charity registrations so you stay mission-focused.

Nonprofits are unique. You don't pay income tax, but you face compliance requirements that for-profits don't. The IRS doesn't send you a refund if you mess up; it revokes your status.

Form 990 is mandatory for organizations with gross receipts over $50,000. Miss three consecutive filings? The IRS automatically revokes your tax-exempt status. No warning. No appeal. Your donors lose their deduction. Your credibility evaporates.

Key Insight

700,000+ Nonprofits Lost Tax-Exempt Status

The IRS has auto-revoked over 700,000 nonprofits for failing to file Form 990s. Many were operating legitimately but got buried in compliance details. One administrative failure doesn't just cost money; it can kill your organization.

Beyond 990s, nonprofits manage:

  • UBIT exposure: Unrelated business income triggers federal taxes
  • State registration: Charity registration required in most states where you solicit donations
  • Employment taxes: Still apply; misclassification creates liability
  • Audit risk: Form 990 is public and triggers IRS scrutiny
  • Board governance: Directors need fiduciary duty protections and conflict-of-interest policies

Taxstra handles all of this. You focus on your mission. We protect your status.

Form 990: More Than Just a Tax Return

It's your organization's financial narrative, and it's public.

Form 990 isn't just compliance. It's your organization's financial autobiography, reviewed by donors, grant-makers, and watchdog organizations like GuideStar (now Candid), Charity Navigator, and the BBB Wise Giving Alliance.

Watch Out

Executive Compensation Under Fire

Form 990 discloses executive salaries, benefits, and severance. If compensation seems excessive relative to mission impact, major donors question your priorities. Grant-makers scrutinize it. It can kill future funding opportunities. The IRS also watches for 'unreasonable' compensation; get it wrong and face excise taxes.

Your 990 shows:

  • Program spending (donors want 75%+ going to programs, not overhead)
  • Fundraising costs (high ratios trigger watchdog downgrades)
  • Executive compensation (absolute numbers and reasonableness)
  • Related-party transactions (conflicts of interest)
  • Governance structure (board independence, audit committee)

UBIT: The Tax Nonprofits Don't Expect

Tax-exempt status doesn't mean all income is tax-exempt.

Many nonprofits generate side income: advertising, rental properties, conference fees, or ancillary business activities. Not all of it is protected.

Key Insight

UBIT Threshold: $1,000

If unrelated business income exceeds $1,000 in a tax year, you must file Form 990-T and pay corporate-level taxes on that income. Many nonprofits don't track this until tax time, then face surprise bills. We help you identify UBIT exposure upfront.

Common UBIT traps:

  • Rental income from debt-financed property: If you financed the purchase with debt, rental income is UBIT
  • Advertising revenue: Magazine ads, website sponsorships, event programs all trigger UBIT
  • Unrelated business activities: If you run a side venture (bookstore, consulting, catering), it generates UBIT
  • Donated property: If you receive a building and rent it, carefully track what's UBIT

Proper UBIT planning can save thousands annually and prevent compliance disasters.

Financial Management & Board Governance

Strength at the top protects the mission.

Beyond tax compliance, nonprofit financial health depends on sound internal systems.

Fund Accounting

Nonprofits use fund accounting to separate restricted and unrestricted money. Restricted donations must be spent per donor intent; violating that trust is both a legal and moral failure. Proper fund tracking prevents year-end crises.

Grant Compliance & Reporting

Grants come with strings: specific reporting, expense documentation, outcome metrics. Failing to meet grant terms risks clawback of funds and permanent ineligibility. We ensure you meet every requirement.

Audit Requirements

Many states require audits above certain revenue thresholds (typically $500K-$1M+). A clean audit is required for loans, grants, and donor confidence. We coordinate audits and ensure financial controls are airtight.

Board Oversight & Liability

Board members have fiduciary duties. Adequate financial reporting, internal controls, and conflict-of-interest policies protect the board and organization. We help boards understand their financial responsibilities.

Frequently Asked Questions

Answers to the questions we hear most.

Do nonprofits really need a CPA?

Yes. Form 990 is public, it shapes donor perception, and it triggers IRS audits. A CPA prevents costly mistakes, ensures compliance, and helps you tell your financial story accurately. Most foundations and major donors expect professional financial management.

What happens if we don't file our 990?

The IRS automatically revokes tax-exempt status after three consecutive years of non-filing. Once revoked, regaining status is expensive and time-consuming. Your donors lose their deduction incentive. Your organization loses credibility. Prevention costs far less than restoration.

What is UBIT and does it apply to us?

UBIT (Unrelated Business Income Tax) applies when a nonprofit generates income from activities unrelated to its mission, like advertising revenue, unrelated rental income, or side business ventures. If UBIT exceeds $1,000, you must file Form 990-T and pay corporate-level taxes. Many nonprofits don't realize their activities trigger UBIT.

How should we handle restricted donations?

Restricted donations must be tracked separately and spent according to donor intent. Fund accounting separates restricted and unrestricted funds. Violating restrictions damages donor relationships and can trigger audits. Proper tracking from day one prevents catastrophic year-end problems.

Do you help with state charity registrations?

Yes. Nonprofits must register to solicit donations in most states, and requirements vary widely. We handle state-level compliance so you stay registered in every state where you fundraise. One missed state can halt campaigns and create legal liability.
