Services
Audit and assurance
An audit is an independent CPA firm's examination of your financial statements, ending in a written opinion on whether they are fairly presented under the accounting framework you use (usually US GAAP).
Tax advisory and compliance
Tax compliance is preparing and filing returns: federal, state and local income tax, sales and use tax, payroll tax, and information returns such as Forms 1099.
Not listed on the firm’s website: SOC 1 / SOC 2, Client accounting. If you need it, ask the firm directly.
Industry niches
Technology and software
Software and SaaS companies face revenue recognition questions under ASC 606, capitalized development costs, research credits, equity compensation and sales tax on digital products in many states, and their customers often ask for SOC 2 reports.
Construction
Contractors are judged by sureties and banks on their financial statements: percentage-of-completion revenue, work-in-progress schedules and bonding capacity. A firm that knows what sureties look for writes statements they accept.
Health care
Health care providers deal with payer reimbursement, cost reports, regulatory compliance and physician compensation rules. A firm with health care clients knows the reporting regulators and lenders expect.
Real estate
Real estate owners and developers rely on partnership tax planning, depreciation and cost segregation, 1031 exchanges and investor reporting. Audits for lenders and investors have their own fair-value and lease questions.
Banks and financial services
Banks, credit unions and other financial institutions are examined by regulators and may need audits under FDICIA, internal audit support and regulatory compliance reviews. Experience with your regulator matters.
Government and public sector
State and local governments report under GASB standards and, when they spend federal awards, need Single Audits. Many are selected through formal procurement, where a firm's government experience is scored.
What to ask Deloitte
- Is Deloitte licensed in our state, and is the partner who would sign our work a licensed CPA there? (Check on CPAverify before the first call.)
- What was the result of your most recent AICPA peer review, and can we see the report?
- Who will be our day-to-day contact, and how often will we speak with the partner?
- How will you bill us: fixed fee, hourly or retainer? What is included, and what would cost extra?
- If we are a public company or broker-dealer: is the firm registered with the PCAOB, and what did its latest inspection report find?
- Who prepares our returns and who reviews them? Is the reviewer a CPA or an enrolled agent?
- Which regulators do your financial institution clients report to?
- How many governmental audits under GASB do you perform?
- Which kinds of providers do you serve: hospitals, physician groups, behavioral health, senior living?
