Surety Bonding and CPA-Prepared Financial Statements: What Your Surety Wants to See in 2026

If your construction company is bidding bonded work above $2 million, the quality of your financial statements directly affects whether you get the bond and how much capacity you qualify for. Surety underwriters are not evaluating whether you can build the project. They are evaluating whether your business can survive a project going sideways without dragging the surety down with it.

This guide covers why CPA-prepared financials matter for bonding, what level of assurance you need at different thresholds, and the specific metrics underwriters calculate when they open your file.

Why Sureties Require CPA-Prepared Financial Statements

A surety bond is a guarantee. The surety company is telling the project owner that if your company fails to perform or fails to pay its subcontractors and suppliers, the surety will step in. That guarantee is backed by the surety’s assessment of your financial strength, which starts with your financial statements.

Internally prepared statements, even accurate ones, carry no independent verification. The surety has no way to confirm whether the numbers reflect reality or optimism. CPA-prepared statements solve this problem by introducing a third party who applies professional standards to the financial data. The higher the level of CPA assurance, the more confidence the surety has, and the more bonding capacity it will extend.

There is also a practical consideration: construction accounting is unlike most other industries. Revenue recognition under the percentage-of-completion method, work-in-progress adjustments, overbilling and underbilling positions, and retainage accounting all require specialized knowledge. A CPA who understands construction will prepare statements in the format underwriters expect, with the WIP detail and cost-method disclosures they rely on. A general accountant may produce statements that are technically correct but miss the presentation details underwriters rely on.

What Level of Financial Statement Do You Need?

The level of CPA assurance your surety requires depends on the size of the bonds you need and your annual revenue. These are general industry thresholds; individual sureties may vary.

Understanding the Three Levels of CPA Assurance

Compilation. The CPA organizes and presents your financial data in GAAP format but does not verify the underlying numbers. No assurance is provided. Compilations are a step up from internal statements and are acceptable for many bond programs up to roughly $1 million in capacity, though acceptance varies by surety.

Review. The CPA performs analytical procedures, compares ratios to industry benchmarks, inquires about significant transactions, and issues a report stating they are not aware of any material modifications that should be made to the financial statements. This provides limited assurance. Reviews are the standard for most mid-size bond programs and are sufficient for most contractors generating between $5 million and $50 million in revenue.

Audit. The CPA independently verifies account balances, sends confirmations to customers and vendors, tests a sample of transactions, examines internal controls, and issues an opinion on whether the financial statements present fairly the company’s financial position. This is the highest level of assurance. Audits are commonly required for contractors with aggregate bonding capacity above $20 million, and become standard for contractors generating revenue above $75–$100 million.

One important note: upgrading from compiled to reviewed statements is not instant. Moving to a higher service level requires time for the CPA firm to build familiarity with your internal controls and financial processes. If you anticipate needing reviewed or audited statements for upcoming bids, start the relationship with a construction-focused CPA now, not when the bid is due.

What Surety Underwriters Look For in Your Financials

Surety underwriting follows a consistent framework built around three pillars: character (how you run your business), capacity (your ability to perform the work), and capital (your financial strength). The financial statement evaluation falls primarily under capital, and underwriters calculate a specific set of ratios when they open your file.

Working Capital

Working capital (current assets minus current liabilities) is often the single most important number in surety underwriting. It measures your short-term liquidity and your ability to fund daily operations, make payroll, pay subcontractors, and absorb unexpected costs without running out of cash.

Sureties generally apply a multiplier of 10x to 15x adjusted working capital to estimate your maximum single bond capacity, and 15x to 20x for your aggregate bonding program. Two examples:

• $500,000 in adjusted working capital: could qualify for a $5 million to $10 million aggregate bonding program.
• $3 million in adjusted working capital: might carry $45 million in aggregate capacity (15x) and $30–$45 million in single-bond capacity, with a strong track record pushing toward the upper end.

Underwriters typically “adjust” working capital by discounting or removing items that are not readily convertible to cash: related-party receivables, inventory, prepaid expenses, and notes receivable from owners. The adjusted number is what drives capacity, not the raw balance-sheet figure.

Net Worth (Equity)

Net worth (total assets minus total liabilities) shows the equity cushion protecting the surety. A healthy equity position indicates that the owners have invested in the business and retained earnings over time rather than distributing all profits. Sureties want to see equity that has grown alongside (or faster than) revenue, with retained earnings building rather than being distributed out as profits are earned.

Sureties also watch equity trends. Consistent growth in equity year over year is a positive signal. Flat or declining equity, especially when combined with increasing revenue, suggests the company is growing faster than it is capitalizing, which raises risk.

Backlog-to-Equity Ratio

Backlog-to-equity compares your total uncompleted work under contract to your net worth. It answers the question: how much work are you carrying relative to the capital base supporting it?

There is no universal threshold, but most underwriters become cautious when backlog-to-equity exceeds 10:1 to 15:1. A contractor with $2 million in equity carrying $30 million in backlog is leveraging every dollar of equity against $15 of uncompleted work. If a single project goes bad, the loss can consume the entire equity position.

Contractors who maintain backlog-to-equity below 10:1 with consistent profitability are in the strongest position for capacity increases.

Debt-to-Equity Ratio

The debt-to-equity ratio measures how much debt you carry relative to your capital base. Most underwriters prefer to see this ratio below 2:1, with the industry median sitting near 1.2–1.3 per CFMA Benchmarker data. Excessive leverage indicates financial risk and reduced capacity to absorb losses. Construction firms often carry equipment debt and working capital lines, but the total should remain manageable relative to equity.

Profitability Trends

Sureties want to see consistent profitability rather than one exceptional year. Three years of steady net margins in the 5%–8% range tells an underwriter more than a single year at 15% followed by a loss. Underwriters also compare your margins to industry benchmarks: if the average GC earns 5%–6% net and your statements show 2%, they will ask what is different about your operation.

The WIP Schedule: Your Surety’s X-Ray

If the financial statements are the foundation of surety underwriting, the work-in-progress schedule is the diagnostic tool. The WIP shows every active project with costs incurred to date, estimated costs to complete, total estimated revenue, billings to date, and the resulting over- or underbilling position. It is the only document that connects your income statement, balance sheet, and project-level performance into a single view.

What underwriters look for in your WIP:

Overbillings vs. underbillings. Moderate overbillings (billing ahead of earned revenue) are healthy and expected. They indicate that you are collecting cash ahead of cost. Excessive overbillings, however, can signal front-loaded billing that creates a future cash gap, or worse, “job borrowing” where cash from one project is used to cover losses on another. Persistent underbillings (costs ahead of billings) mean you are financing the project owner’s work. Both positions need explanations.

Profit fade. When estimated gross profit at completion drops below the margin projected at bid, the project is fading. Fade across multiple projects is a red flag that estimating, project management, or change order recovery is broken. Underwriters will compare the estimated margin at bid to the current estimated margin and ask about any project where the two numbers have diverged.

Cost-to-complete reliability. The entire WIP schedule depends on accurate cost-to-complete estimates from project managers. If those estimates are not updated monthly, the WIP produces stale numbers that hide problems. Underwriters can usually tell whether cost-to-complete figures are actively managed or left untouched from bid.

Percentage-of-completion method. Sureties expect financial statements prepared using the percentage-of-completion (POC) method for revenue recognition, not the cash method or completed-contract method. POC matches revenue to the progress of work, which gives the surety a real-time picture of financial position. If your statements are prepared on a cash basis, most sureties will require conversion to POC before they can underwrite your program.

Timing and Presentation

Beyond the numbers themselves, two practical factors affect how underwriters perceive your file:

Submit year-end statements within 90 to 120 days. If your fiscal year ends December 31, your CPA-prepared statements should be in your bond agent’s hands by late March or early April. Late statements signal weak financial discipline, and underwriters notice. Do not wait for your surety to ask.

Keep interim statements current. Between year-end CPA statements, sureties want to see quarterly or monthly internal financial statements and a current WIP schedule. These interim statements should tie to the most recent CPA-prepared version. Discrepancies between your internal statements and your CPA statements create questions about the reliability of both.

Common Mistakes That Reduce Bonding Capacity

Several issues come up repeatedly when contractors wonder why their bonding capacity is lower than expected:

• Tax returns do not match financial statements. If your CPA statements show $3.2 million in revenue and your tax return shows $2.8 million, the underwriter will flag the discrepancy. Different accounting methods can explain the gap, but the reconciliation needs to be documented.
• Excessive owner distributions. Owners who distribute all profits leave thin equity. Sureties view this as a sign that the owners are prioritizing personal liquidity over business capitalization. Retained earnings build equity and bonding capacity.
• Related-party transactions. Loans to owners, receivables from related entities, and intercompany transactions obscure the true financial position. Underwriters discount or eliminate these items when calculating adjusted working capital.
• Using a general CPA. A CPA unfamiliar with construction accounting may prepare technically correct statements that miss WIP presentation, overbilling/underbilling classification, or percentage-of-completion adjustments. This creates delays, rework, and sometimes denied applications.
