A retirement compensation arrangement (RCA) is a formal employer-sponsored plan used to set aside funds for an employee's retirement beyond what registered pension plans allow. In Canada, the Canada Revenue Agency treats these plans as a distinct tax vehicle, and employers must register them and withhold a 50% refundable tax on contributions.
That tax treatment surprises many business owners who assume a supplemental retirement promise works like an ordinary pension. The problem is real: without proper structure, an informal promise to pay retirement benefits can trigger compliance issues and unexpected tax bills.
This guide explains how an RCA works, who uses one, the tax mechanics, and the practical steps to set one up correctly.
What Is a Retirement Compensation Arrangement and How Does It Work?
A retirement compensation arrangement is a trust-based plan that an employer establishes to provide retirement benefits that fall outside registered pension limits. The employer contributes to a trust, and a custodian holds the assets for the employee's future benefit.
Three structural pieces define how it operates:
- The employer funds the plan and claims the contribution as a business deduction.
- The custodian holds and invests the assets in trust.
- The CRA administers a refundable tax account tied to the plan.
Under the Income Tax Act, an RCA must be a prescribed arrangement, and the employer generally must file to register it. Unlike a Registered Retirement Savings Plan, contributions are not limited by a fixed annual dollar cap in the same way, which is why executives and high earners use them for supplemental retirement income.
The tax authority's own guidance frames the plan as a way to defer compensation, but with a cost: the refundable tax mechanism is designed to prevent unlimited tax deferral. According to the Canada Revenue Agency, employers must remit the 50% refundable tax on contributions and can recover it when benefits are paid out.
A useful distinction: an RCA is a contractual trust arrangement, not an insurance product, so the employer bears the investment risk on the trust assets.
How to apply this: Confirm whether your plan must be registered as a retirement compensation arrangement before you promise any supplemental retirement benefit, and check the current CRA filing requirements before contributing.
Who Actually Uses a Retirement Compensation Arrangement? The Key Beneficiaries
The primary users are executives, business owners, and professionals whose retirement savings exceed registered plan limits. The structure is most common in owner-managed corporations and among senior staff in industries with high compensation.
The main beneficiary groups include:
- Business owners who want to extract value from a corporation tax-efficiently at retirement.
- Executives receiving supplemental retirement promises as part of a compensation package.
- Key employees whose pension benefits exceed registered plan maximums.
- Professional corporations looking for an additional retirement vehicle.
The rationale is straightforward. When an individual has already maximized RRSP and registered pension contributions, a retirement compensation arrangement offers a further tax-deferred option. Many advisors note that the 50% refundable tax makes the structure less attractive for short-term deferral but potentially workable for long-horizon retirement planning.
One practical consideration: the plan is typically drafted by a lawyer and administered by a trust company, so setup costs are meaningful. Small employers often find the economics don't justify an RCA until compensation levels are high enough.
How to apply this: List your expected retirement income sources and identify whether registered plan limits will fall short. If they will, a retirement compensation arrangement may be worth a formal cost-benefit review.
The 50% Refundable Tax: How the Retirement Compensation Arrangement Tax Mechanics Work
The refundable tax is the defining feature of an RCA. When an employer contributes, 50% of the contribution goes to a refundable tax account with the CRA, and the other 50% is invested in the trust.
Two things happen over time:
- The refundable tax account earns no investment return for the plan, which reduces net growth.
- When benefits are paid to the employee, the CRA refunds the tax to the plan and the employee pays income tax on the benefit.
This creates a timing trade-off. The employer gets a deduction when contributing, the trust grows only on half the money during the deferral period, and the employee is taxed on receipt.
The CRA's guidance is explicit that the tax is refundable, not lost. But many plan sponsors underestimate how much the tax drag reduces long-term returns.
A common scenario is an owner who contributes steadily for fifteen years and is surprised that the trust balance is lower than a simple projection suggested, because half the contributions sat in a non-earning tax account.
Investment income earned inside the trust also attracts the refundable tax treatment, which compounds the drag. Many advisors model the plan both with and without the refundable tax before recommending it.
How to apply this: Ask your accountant to run a projection showing trust growth after the refundable tax drag before you commit to contribution levels.
Retirement Compensation Arrangement vs Other Plans: A Practical Comparison
Choosing a plan is easier when you compare the core features side by side. The table below summarizes how an RCA differs from common retirement vehicles.
| Feature | RCA | RRSP | Registered pension |
|---|---|---|---|
| Contribution limit | Flexible, set by plan | Capped annually | Capped by formula |
| 50% refundable tax | Yes | No | No |
| Employer deduction | Yes | No (personal) | Yes |
| Who bears investment risk | Employer/trust | Individual | Plan/employer |
| Best use case | High earners over limits | General savers | Employees in group plans |
| Action to take | Model tax drag | Maximize room first | Review plan terms |
The comparison makes one point clear: a retirement compensation arrangement is a supplemental tool, not a replacement. Most advisors recommend maximizing RRSP and registered pension room before layering an RCA on top.
One key difference is control. In an RCA, the employer controls the plan and the trust, which can be an advantage for an owner-managed business but a limitation for employees who want direct investment control.
How to apply this: Fill in the table above for your own situation, starting with a review of your registered plan room before you consider a retirement compensation arrangement.
How Do You Set Up a Retirement Compensation Arrangement Step by Step?
Setup follows a defined sequence. The plan must be documented, registered with the CRA, and funded through a trust with a custodian.
Follow these steps:
- Define the benefit. Decide what retirement income the plan will provide and to whom.
- Draft the plan document. Engage a lawyer experienced in executive compensation.
- Appoint a custodian and trustee. Many trust companies offer RCA administration.
- Register the plan with the CRA and obtain the appropriate account.
- Fund the trust and remit the refundable tax each year.
- File annual returns and track the refundable tax balance.
Administration is ongoing. Each contribution triggers a remittance, and each benefit payment triggers a refund claim. Using a professional administrator reduces error risk, and tools like a tax-software ledger can help track the refundable tax account.
The IRS equivalent concept, a nonqualified deferred compensation plan under Section 409A, differs significantly from the Canadian RCA, so cross-border employers should not assume the rules mirror each other.
How to apply this: Draft a one-page plan summary defining benefits and funding before contacting a lawyer, so the drafting process starts with clear goals.
Common Retirement Compensation Arrangement Mistakes to Avoid
Most problems stem from documentation and tax-tracking errors. A retirement compensation arrangement that is set up informally is the biggest risk.
The most common mistakes include:
- Operating an unfunded promise without a registered trust. This can create unintended tax consequences.
- Forgetting the refundable tax remittance. Late remittances trigger penalties.
- Underestimating the tax drag. Projections that ignore the 50% refundable tax overstate returns.
- Failing to file annual returns. Missing filings can jeopardize the plan's status.
- Not reviewing the plan as tax law changes. Rules evolve, and stale plans drift out of compliance.
One case worth noting: an employer that pays retirement benefits directly from company cash without a trust may inadvertently create a salary-deferral arrangement outside the RCA rules, exposing both parties to tax reassessment.
Good governance means an annual review of contributions, refundable tax balances, and investment performance. Many plan sponsors schedule this review alongside their corporate year-end tax planning.
How to apply this: Add an annual RCA compliance checklist to your corporate calendar covering remittances, filings, and a performance review of the trust.
Frequently Asked Questions About retirement compensation arrangement
What happens to the refundable tax if the plan is wound up?
When a plan winds up, the CRA refunds the refundable tax balance remaining in the account as benefits are paid out. The key exception is that the refund follows the benefit payments, so a rushed wind-up can leave tax tied up longer than expected.
Plan the wind-up timeline with your administrator, and confirm the final refundable tax balance before closing the retirement compensation arrangement.
Can an employee contribute to an RCA?
Generally no. A retirement compensation arrangement is employer-funded, and employee contributions are not a standard feature. The exception arises in plans designed for owner-employees, where the individual effectively funds the plan through the corporation. If you are an employee rather than an owner, confirm contribution rules in the plan document before assuming you can add your own money.
Is an RCA better than a salary deferral arrangement?
They serve different purposes. A salary deferral arrangement defers current salary, while a retirement compensation arrangement funds retirement income. The exception is a plan that combines both features, which requires careful drafting to avoid tax reassessment. If your goal is retirement income rather than short-term deferral, the RCA structure usually fits better.
How is an RCA taxed in the United States?
The U.S. does not use the term the same way. American employers typically use nonqualified deferred compensation governed by Section 409A, which has different timing and funding rules. The exception is a cross-border employee covered by a tax treaty, where coordination rules may apply. Confirm treatment with a cross-border tax advisor before assuming a Canadian RCA is recognized.
What is the minimum contribution to start an RCA?
There is no official minimum, but practical costs make small contributions inefficient. Setup and administration fees mean a retirement compensation arrangement usually only makes sense once contributions reach a meaningful annual level. The exception is an owner who wants to start early for long-term compounding. Run a cost-benefit model before committing to a minimum funding level.
Key Takeaways and Your Next Step
A retirement compensation arrangement is a specialized, employer-funded trust that provides supplemental retirement income beyond registered plan limits. The details that matter most:
- The 50% refundable tax on contributions is the defining cost, and it reduces net growth.
- Executives and business owners are the main users, typically after maximizing RRSP room.
- Proper registration, a trust, and annual compliance are non-negotiable.
- Modeling the tax drag before contributing prevents unpleasant surprises.
Your next step is to request a written projection from your accountant comparing registered savings alone against a layered retirement compensation arrangement. If the numbers support it, engage a lawyer and a trust company to draft and register the plan properly.
