Not every association needs an audit. Most need to check.

Audit and review are not the same engagement
An audit is the higher level of assurance: a CPA tests internal controls, independently verifies account balances, and provides an opinion that the financial statements fairly represent the association's position. A review is lighter — the CPA performs analytical procedures and inquiry, providing limited assurance, without the same depth of independent verification. A review costs meaningfully less than an audit, which is exactly why the threshold that triggers one versus the other matters to a board managing a limited operating budget.
How the trigger is typically structured
States that impose a mandatory requirement usually key it to one or both of two figures: the association's annual revenue and its number of units or lots. A common structure sets a revenue threshold that triggers a review, a higher revenue threshold that triggers a full audit, and in some states a separate unit-count threshold that operates independently of revenue — meaning a large association with modest per-unit dues can still cross the audit trigger purely on unit count, even if the raw revenue figure looks unremarkable.
Where the CC&Rs fill the gap
In states with no statutory audit trigger, or for associations below the statutory threshold, the CC&Rs frequently impose their own requirement — sometimes an audit every year, sometimes only when a specified percentage of the membership petitions for one. A board should check both layers separately: passing below the statutory threshold doesn't mean the association is off the hook if the CC&Rs impose a stricter standard of their own.
Confirm your state's current revenue and unit-count audit/review thresholds → confirm whether the CC&Rs impose a stricter independent requirement → determine which side of the threshold the association currently falls on → engage a CPA at the correct engagement level, not automatically the more expensive one → document the board's threshold determination in the minutes.
Below the threshold isn't the same as no requirement
Do not assume every association below an audit or review threshold automatically owes a compilation. State statutes use different financial-reporting ladders, and some governing documents impose a stricter service than the statute. Determine the required product — if any — from the current statute and the governing documents first. Then separately decide whether the board wants a higher level of assurance for risk management: an outside set of eyes on the books, even a modest engagement, is one of the cheapest protections against an undetected shortfall, the same internal-control logic that applies to combining the secretary and treasurer roles.
Membership can sometimes waive or force the requirement
Several states let the membership vote to waive a statutory audit requirement in a given year — useful for a small association trying to control costs — but that waiver typically has to be renewed and documented annually, not assumed to carry forward silently. The reverse also exists in some states: a specified percentage of owners can petition to force a review or audit even when the association falls below the mandatory threshold, which is a mechanism boards should be aware exists before treating "we're below the line" as the final word.
A worked example: crossing the threshold without noticing
An association budgeted for a review-level engagement for years, comfortably below its state's audit-triggering revenue threshold. Then it approves a significant assessment increase to fund a deferred capital project, and the resulting annual revenue crosses into audit-trigger territory for the first time. If nobody on the board re-checks the threshold after approving the new budget, the association may proceed with the same review-level engagement it always uses — which no longer satisfies the statutory requirement now that revenue has moved. This isn't a hypothetical edge case; it's the single most common way associations end up out of compliance on this specific requirement, because the trigger is tied to a number that changes whenever the budget does, and nobody owns the job of re-checking it every year.
Building the re-check into the annual budget process
The fix is straightforward: whoever finalizes the annual budget should also confirm, as a standing last step, whether the newly-approved revenue figure crosses any audit or review threshold — before the engagement letter for the year's CPA work goes out, not after the wrong-level engagement is already underway. This is a five-minute check against a number the board already has in front of it, and it's considerably cheaper than discovering after the fact that a full year's financials need to be re-examined at the higher assurance level to satisfy the statute.
An audit is a governance tool, not just a compliance cost
Boards sometimes frame the audit or review requirement purely as an expense to minimize, which misses half of what the engagement actually does. An outside CPA's independent look at the books is one of the few checks available against an undetected error or shortfall in a volunteer-run organization with limited internal financial expertise — treating it strictly as a box to check, rather than as real oversight the board benefits from, is a missed opportunity even in years the association technically falls below the mandatory threshold.
Comparing engagement quotes before committing
Once the board knows which engagement level it actually needs, it's worth getting more than one CPA quote rather than automatically renewing with whoever handled last year's engagement, particularly for a first-time audit after crossing a threshold — audit fees for community associations vary meaningfully by firm, and a firm with genuine experience in this niche is often both more accurate and, over time, no more expensive than a generalist firm learning the association's books for the first time.
What a complete audit-determination file should contain
- The current state statute's revenue and unit-count thresholds.
- The CC&Rs' own audit or review requirement, if any.
- The association's current revenue and unit count, documented for comparison.
- Board minutes recording the threshold determination each year.
- Any membership waiver or petition affecting the requirement, with its vote count.
Matching the engagement level to your actual numbers
A CPA experienced in community-association accounting should confirm which engagement level — compilation, review, or audit — actually matches your association's current numbers before the board budgets for one. An association attorney should be consulted if the board is considering asking members to waive a statutory requirement, since the waiver procedure itself is often more specific than boards expect.
Frequently asked questions
- Does every HOA need a CPA audit every year?
- No. Some states use different financial-reporting levels based on association type, revenue, member vote, or other statutory criteria, while many communities also have requirements in their governing documents. Confirm the statutory threshold and any stricter declaration or bylaws requirement before treating an audit, review, or compilation as mandatory.
- What is the difference between an audit and a financial review for an HOA?
- An audit provides a higher level of assurance and includes more extensive testing, while a review provides limited assurance based mainly on analytical procedures and inquiries. A compilation provides still less assurance. Which service is legally required is a separate question from which service the board may choose for risk management.
- Can HOA members waive a required audit or review?
- Some state statutes permit a member vote to reduce or waive a specified level of financial reporting, while others do not or limit how often it can occur. The board should verify the waiver procedure before substituting a lower service.
