For many nonprofit leaders, Form 990 season sneaks up quietly.

January feels like a fresh start. February is about getting the year moving. And then suddenly it’s March — and someone mentions that the May 15 Form 990 deadline is only a couple of months away.

For nonprofits with a December 31 year-end, this is the moment when 990 preparation should really begin. Waiting until April almost always leads to one thing: rushing, scrambling, or filing an extension. And while extensions are common, they’re rarely ideal.

 

Why Mid-March Is the Right Time to Start Preparing

Form 990 isn’t just another tax form. It’s a public document that tells the financial story of your organization.

Donors read it.
Grantmakers review it.
Board members reference it.

Preparing it properly requires more than simply handing documents to an accountant a few weeks before the deadline.

That’s why nonprofit 990 filing preparation should begin now — while there’s still enough time to review your books calmly and make sure everything truly reflects the year that just ended. Think of it as organizing the story of your organization before someone else reads it.

 

Start With Clean, Finalized Books

The biggest reason nonprofits struggle with 990 preparation is simple: the books aren’t fully closed.

Before your tax preparer can complete the filing, your organization should have:

  • All bank accounts reconciled
  • Credit card transactions recorded
  • Payroll expenses finalized
  • Year-end adjustments entered
  • Accurate revenue and expense categories

This is where bookkeeping matters more than most leaders realize.

If the financial records aren’t clean, the 990 process turns into detective work. Instead of focusing on telling the story of the organization, everyone ends up trying to figure out what actually happened financially. That slows everything down.

 

Review Your Payroll Records

Payroll often creates small surprises during 990 preparation. Even when payroll runs smoothly throughout the year, it’s important to confirm:

  • Wages and benefits are categorized correctly
  • Payroll tax filings match payroll reports
  • Any contractor payments were properly recorded
  • Leadership compensation is documented clearly

Form 990 asks specific questions about compensation and employee structure, so having this information organized early helps avoid last-minute corrections.

 

Confirm Your Revenue Categories

Another area that frequently delays nonprofit 990 filing preparation is revenue classification. Not all income is treated the same way on Form 990. Contributions, grants, program service revenue, and fundraising income are reported differently.

Now is a good time to review questions like:

  • Were donations recorded correctly?
  • Are restricted grants clearly tracked?
  • Are fundraising event proceeds categorized properly?

These details matter because they affect how your nonprofit appears publicly on its 990. A well-prepared return helps readers understand the strength and stability of your organization.

 

Gather Key Organizational Information Early

Your tax preparer will also need several organizational details that leaders often scramble to locate at the last minute.

For example:

  • Updated board member list
  • Officer compensation details
  • Major program descriptions
  • Fundraising activity summaries
  • Governance policies

These are easier to gather now, while there’s time to review them carefully. Waiting until April often means searching through emails, board minutes, and documents while the deadline gets closer.

 

Why Filing an Extension Isn’t Always the Best Option

Many nonprofits assume filing an extension is harmless. Technically, it gives you more time — but it also creates a few challenges.

First, the work doesn’t disappear. It simply moves into the middle of the year, when organizations are already busy with programs, fundraising, and planning.

Second, extensions can create unnecessary stress. When the process stretches longer, questions tend to pile up and financial details become harder to track.

Finally, timely filing helps maintain confidence with stakeholders. Donors, funders, and board members appreciate organizations that stay on top of their reporting responsibilities.

In short, avoiding an extension keeps the process simpler and calmer.

 

What a Smooth 990 Season Looks Like

When nonprofit 990 filing preparation starts early, the experience feels very different.

Instead of scrambling in April, leaders are able to:

  • Review their financials with confidence
  • Provide accurate information quickly
  • Finalize the return well before the deadline

Most importantly, the organization’s financial story is presented clearly — which is exactly what Form 990 is meant to do.

 

A Gentle Nudge Forward

Most nonprofit leaders don’t think about Form 990 until someone reminds them the deadline is approaching.

But starting preparation in March can make the entire process calmer.

If your organization’s books still need attention, or if payroll and financial records haven’t been fully reviewed yet, this is the right moment to get ahead of the filing season.

And if talking through your organization’s readiness for the upcoming 990 would be helpful, we’re always happy to have that conversation.
