BDO USA is a large accounting and advisory firm, not a government agency or tax software
BDO USA is a private accounting and consulting company that serves businesses, nonprofits, and individuals. They offer tax preparation, audit, accounting, and advisory services — but they are not the IRS, not a government program, and not a tax software you read yourself. If you work with BDO, you are hiring their accountants and consultants as employees or contractors to handle your financial work.
BDO is one of the largest accounting firms in the United States by revenue and employee count. They have offices in most major cities and serve clients ranging from small businesses to Fortune 500 companies. For tax purposes, this means BDO can prepare your tax return, represent you before the IRS, or help you understand tax strategy — but you pay them for that service, and you choose whether to hire them.
This guide explains what BDO does, who typically hires them, and how they differ from other ways to handle your taxes or accounting.
Key Takeaways
- BDO is a private accounting firm you hire and pay; they are not a government agency, tax software, or free service.
- They offer tax preparation, audits, bookkeeping, and business consulting to clients who can afford their fees.
- Small business owners, nonprofits, and individuals with complex tax situations are common BDO clients.
- You can prepare your own taxes, use tax software, hire a local CPA, or hire BDO — each route has different costs and complexity.
- BDO can represent you before the IRS if you are audited or have a tax dispute, but you must hire them first.
What services BDO actually provides
BDO's main service lines are tax, audit, accounting, and advisory. For tax work, they prepare individual and business returns, handle tax planning before the year ends, and represent clients in disputes with the IRS. For audit work, they examine a company's financial records and issue a report on whether the statements are accurate — this is often required by lenders, investors, or law. For accounting, they set up bookkeeping systems, process payroll, and manage accounts payable and receivable. For advisory, they consult on mergers, restructuring, risk management, and other strategic decisions.
The specific service you would use BDO for depends on your situation. A sole proprietor with one W-2 job and no business income probably does not need BDO — tax software or a local CPA is cheaper and faster. A small business owner with employees, inventory, and quarterly tax payments might hire BDO for bookkeeping and tax planning. A nonprofit might hire BDO to prepare their Form 990 (the tax return nonprofits file) and conduct an audit if donors or grants require one. A business owner considering selling the company might hire BDO to advise on the sale structure and tax consequences.
How BDO's fees work and what to expect
BDO charges by the hour or by project, depending on the work. Hourly rates vary by location, the seniority of the staff assigned, and the complexity of the work. A junior accountant in a small office costs less per hour than a senior manager in New York or Los Angeles. Project fees — for example, a flat price to prepare your business tax return — are quoted after an initial consultation.
Because BDO is a large firm with high overhead, their fees are typically higher than a solo CPA or a local accounting practice. This makes sense if you need specialized informed, have a complex situation, or want the backing of a large firm. It does not make sense if your tax return is straightforward and you are price-sensitive. Before you contact BDO, think about whether the complexity of your situation justifies the cost.
BDO does not offer free tax preparation for low-income individuals. If you earn below a certain threshold and need free help, look into the IRS Free File program or Volunteer Income Tax information (VITA) instead.
When to hire BDO versus other options
You have several ways to handle your taxes and accounting. The right choice depends on your income, the complexity of your situation, and your budget.
| Option | Best for | Cost | Effort |
|---|---|---|---|
| Tax software (TurboTax, H&R Block, etc.) | straightforward returns: one job, standard deduction, no business income | $0–$200 per year | You do the work; software guides you |
| Local CPA or tax preparer | Moderate complexity: self-employment, rental income, investments, small business | $500–$2,500 per year | You gather documents; preparer does the rest |
| BDO or large firm | High complexity: multiple entities, audit, strategic planning, representation | $2,500–$50,000+ per year | You provide information; firm handles everything |
| DIY (no help) | Very straightforward returns and high confidence in tax rules | $0 | You do all the work and bear all the risk |
BDO makes the most sense if you own a business with employees, operate multiple business entities, have significant investment income, are involved in a merger or acquisition, or face an IRS audit. If your situation is simpler, a local CPA or tax software will save you money without sacrificing quality.
How to contact BDO and what to prepare
BDO has a website (bdo.com) where you can find their office locations and contact information by state and service line. You can call a local office or submit an inquiry through their website. They will ask you to describe your situation — your industry, revenue, number of employees, whether you have been audited before, and what specific help you need.
Before you contact BDO, gather basic information: your last two years of tax returns, recent financial statements if you own a business, and a list of any tax issues or questions you have. This helps the firm give you an accurate fee estimate. Be clear about what you want — tax preparation only, bookkeeping, audit, or strategic information — because the scope of work drives the cost.
BDO will likely schedule an initial consultation, often free or at a reduced rate, to understand your needs and provide a proposal. Read the proposal carefully and ask about what is included, what is not, and what happens if your situation changes during the year.
BDO's role if you are audited by the IRS
If the IRS audits your return, you can represent yourself, hire a CPA or tax attorney, or hire BDO. BDO has tax professionals who are enrolled agents or CPAs and can represent you before the IRS in most situations. They will request your records from the IRS, review the audit notice, prepare responses, and attend meetings or appeals on your behalf.
Representation is valuable if the audit is complex, involves multiple years, or raises questions about tax strategy. It is less necessary if the IRS is straightforward asking for proof of a deduction you claimed — you can often handle that yourself. If you already work with BDO on your taxes, they have your records and history, which makes representation smoother. If you do not, you will need to hire them specifically for audit defense, which adds to the cost.
Differences between BDO and other accounting firms
BDO is one of the "Big Four" accounting firms in the United States, along with Deloitte, PwC, and EY. These firms are large, national, and expensive. They serve big companies and complex situations. Below them are regional and local firms — some with dozens of offices, some with just one. A solo CPA or small practice is even smaller and cheaper.
The main trade-off is size and specialization versus cost and personal attention. A large firm like BDO can handle a complex multinational business or a major audit. A local CPA knows your community and your industry, charges less, and may give you more direct access to the person doing your work. Neither is universally better — it depends on what you need.
BDO also differs from tax software in that you are not doing the work yourself. You are paying professionals to do it for you, which means higher cost but lower effort and (usually) lower risk of mistakes.
Frequently Asked Questions
Is BDO the same as the IRS?
No. BDO is a private company. The IRS is a government agency. BDO can prepare your taxes and represent you before the IRS, but they cannot change tax law, issue refunds, or make official determinations about your tax liability.
Can I use BDO if I only have a job and no business?
Yes, but it is usually not cost-effective. If you have one W-2 job, take the standard deduction, and have no other income, tax software or a local preparer is cheaper and faster. BDO is better suited to business owners, investors, and people with complex situations.
How long does it take BDO to prepare a tax return?
It depends on the complexity and how quickly you provide documents. A straightforward business return might take two to four weeks. A complex return with multiple entities, audits, or special situations might take six to eight weeks or longer. Ask for a timeline when you get the proposal.
What if I disagree with BDO's information?
You can ask for a second opinion from another CPA or tax attorney. You are not required to follow BDO's recommendations, but if you ignore their information and the IRS later disagrees with your return, you may owe back taxes and penalties. Get information in writing so you understand the reasoning.
Does BDO offer a payment plan for their fees?
Some offices may offer payment plans, but this varies. Ask when you receive the proposal. Many firms expect payment when the work is complete or in installments as the work progresses.
