Best License Combinations for CPAs (2026)

A CPA license is already one of the most respected credentials in the professional services world. But CPAs who add a complementary license can transform their practice from a tax-and-audit shop into a full-service financial hub. The logic is straightforward: your existing clients already trust you with their most sensitive financial information. Adding a credential that lets you serve them in adjacent areas — insurance, real estate investment, or financial advisory — increases your revenue per client without the cost of acquiring new ones.

1. Insurance Agent

The CPA-plus-insurance combination is arguably the most popular license stack in financial services. An insurance agent license lets you sell life insurance, annuities, long-term care insurance, and disability insurance — products that are natural extensions of the retirement planning, estate planning, and risk management conversations you are already having with tax clients.

The trust advantage here is enormous. Your clients already share their income, assets, debts, and family situation with you during tax season. That level of financial transparency makes it easy to identify insurance gaps and recommend appropriate coverage. Many CPAs find that insurance commissions become a significant and recurring revenue stream, especially from whole life and annuity products that pay trail commissions year after year.

Most CPAs pursuing this path start with a life and health (L&H) license rather than property and casualty (P&C), since L&H products align more closely with financial planning conversations. However, adding P&C gives you the ability to write business insurance for your commercial clients as well.

2. Real Estate Broker

If your CPA practice serves clients who invest in real estate — and many practices do — a real estate broker license creates a powerful combination. As a broker, you can earn commissions on investment property transactions, provide more nuanced tax advice grounded in hands-on market knowledge, and manage your own property investments more effectively.

The synergy is especially strong in the areas of 1031 exchanges, cost segregation studies, and depreciation strategies. A CPA who understands both the tax code and the real estate market can offer clients integrated advice that no single-credential professional can match. You become the person who can identify the right investment property, structure the transaction for tax efficiency, and handle the accounting — all under one roof.

Note that some states allow you to sit for the broker exam directly without first working as a salesperson if you meet certain education or professional experience thresholds. Your CPA credential and financial background may qualify you for an expedited path in some jurisdictions.

3. Financial Advisory (Series 65)

While not a “license” in the traditional state-licensing sense, the Series 65 (Uniform Investment Adviser Law Exam) is a critical credential for CPAs who want to provide holistic financial planning and charge fees for investment advice. Passing the Series 65 qualifies you as an investment adviser representative (IAR), enabling you to manage client portfolios, recommend securities, and charge assets-under-management (AUM) fees.

Many CPAs find that transitioning to a fee-based advisory model — where they manage investments in addition to handling tax preparation — dramatically increases their per-client revenue. The typical AUM fee of 0.5%–1.5% on managed assets creates a recurring revenue stream that compounds as your client base grows. This model also increases client retention, since clients are less likely to leave an adviser who manages both their taxes and their investments.

To practice as an investment adviser, you will also need to register with your state securities regulator (or the SEC if you manage over a certain threshold of assets). The compliance and fiduciary requirements are significant, so many CPAs choose to affiliate with an existing registered investment adviser (RIA) rather than starting their own.

How to Plan Your Stacking Order

For CPAs looking to diversify their practice, here is a practical progression:

1. Insurance agent (L&H) first. This is the fastest add-on and the most natural extension of financial planning conversations. You can begin recommending and selling products to existing clients within a few months.
2. Series 65 second. If you want to manage client investments, pass the Series 65 and either join an existing RIA or register your own. This creates a recurring AUM revenue stream.
3. Real estate broker third. Pursue this only if a meaningful portion of your client base invests in real estate. The time commitment is the largest of the three, but the payoff can be substantial for the right practice.

Remember that each credential comes with its own continuing education requirements, ethical obligations, and potential conflicts of interest. Build a compliance calendar that tracks renewal dates, CE deadlines, and reporting obligations across all your credentials.
