What Is the Adjusted Cost Basis (ACB) of a Life Insurance Policy?
By Jose Salloum, Financial Security Advisor (Conseiller en sécurité financière) | May 2026
Important Disclosure — Not Tax Advice: This article is general education about the adjusted cost basis concept as it applies to life insurance policies in Canada. It is not tax advice. The ACB of any specific life insurance policy at any point in time must be obtained from the insurer and reviewed with a qualified Chartered Professional Accountant (CPA) or tax advisor who is familiar with the Canadian tax treatment of life insurance policies before any transaction (surrender, policy loan, or other disposition) is made. The applicable provisions of the Income Tax Act are complex, change over time, and depend on individual circumstances.
Key Takeaways
- The adjusted cost basis (ACB) of a life insurance policy is a tax concept under the Income Tax Act (Canada) that generally represents the amount that can be received from a policy without triggering income inclusion.
- The ACB of a life insurance policy generally declines over time because the Net Cost of Pure Insurance (NCPI) — the pure mortality cost component — is deducted from the ACB each year under the Income Tax Act’s calculation.
- Generally, a policy loan is not a taxable event — it is a loan, not income.
- Each paid-up addition (ASL unit) has its own ACB component that is embedded in the overall policy’s ACB calculation.
The adjusted cost basis. For most Canadians, this phrase appears in the context of selling investments or real estate — the difference between what you paid and what you sold it for, with the excess generally taxable. Life insurance policies have an adjusted cost basis too, but it works quite differently. And understanding how it works — even at a general level — is essential for anyone who takes policy loans from a participating whole life policy or plans to access the cash value in any way.
The ACB of a life insurance policy is not intuitive. It does not equal the total premiums you have paid. It declines over time rather than staying constant. And in older policies, it may be at or near zero — which affects how any money received from the policy is taxed. This article explains the concept at a general educational level. For specific numbers, the insurer and a qualified CPA are the right sources.
The Net Cost of Pure Insurance — Why the ACB Declines
The reason the ACB declines is the Net Cost of Pure Insurance (NCPI). The NCPI is a figure that represents the pure cost of the life insurance protection in a policy — essentially, the mortality cost component. Under the Income Tax Act, the NCPI is deducted from the policy’s ACB each year. As a result, the ACB is progressively reduced by the ongoing cost of the insurance protection the policy provides.
The NCPI generally increases as the insured ages — the cost of insuring an older person’s life is actuarially greater than insuring a younger person’s — so the annual deduction from the ACB grows over time. In a policy that has been in force for many years, the cumulative effect of NCPI deductions can bring the ACB to a low figure or to zero.
This has a practical consequence: in an older, well-established policy, the ACB may be near zero even though the cash surrender value has grown substantially over the years. The gap between the CSV and the ACB represents value that, if received by the policyholder, may generally be included in income under the Income Tax Act’s rules for policy dispositions.
Why the ACB Matters for Surrenders and Policy Loans
When a policy is surrendered (fully or partially). Generally, if a policyholder receives the cash surrender value by surrendering the policy, and that CSV exceeds the ACB at the time, the excess is generally included in the policyholder’s income in that year. For a policy with a zero or near-zero ACB and a large CSV, this can mean a significant income inclusion. This is why surrendering a long-standing participating whole life policy — particularly one with accumulated paid-up additions — may have meaningful tax consequences that should be reviewed with a CPA before any surrender is initiated.
When a policy loan is taken. Generally, a policy loan is not itself a taxable event — it is a loan, not income. But the Income Tax Act has rules that may treat a policy loan as a policy disposition if the outstanding loan exceeds the policy’s ACB. If the loan balance reaches or exceeds the ACB, the excess may be treated as a disposition, triggering income inclusion on that amount. This is one of the most important tax considerations for policyholders who actively use policy loans as part of the Infinite Financial Sovereignty™ strategy — particularly in older policies where the ACB may be low.
Important Disclosure — Policy Loan Tax Treatment: The tax treatment of a policy loan that exceeds the policy’s ACB is a specialized area of Canadian tax law governed by the Income Tax Act. The specific application depends on the policy, the ACB at the time of the loan, the loan amount, and other circumstances. This article is not tax advice. Before taking a significant policy loan — particularly from a policy that has been in force for many years — confirm the current ACB with the insurer and discuss the tax implications with a qualified CPA or tax advisor who is familiar with the Canadian tax treatment of life insurance policies.
Paid-Up Additions and the ACB
Each paid-up addition (ASL unit) credited to the policy has its own ACB component, embedded in the overall policy ACB. When dividends are applied as paid-up additions, they contribute to both the policy’s cash value and to its ACB in a manner set out in the Income Tax Act. The overall policy ACB reflects the cumulative effect of the base policy’s premiums and NCPI deductions, plus the contributions and NCPI deductions from all accumulated paid-up additions.
For a policy that has accumulated paid-up additions over many years, the ACB calculation is correspondingly complex. The insurer maintains this calculation and can provide the current ACB to the policyholder or their advisor on request. For policyholders who are actively using policy loans or considering any form of policy disposition, obtaining this figure from the insurer and sharing it with a CPA is an important step that should not be skipped.
How to Find Your Policy’s ACB
The ACB of a life insurance policy is not typically displayed on annual policy statements. It is a calculated figure that the insurer maintains. To find out the current ACB of a specific policy, the policyholder or their advisor should contact the insurer directly and request the current ACB figure. Many insurers can provide this upon request, and some include it in their administrative documentation for advisors.
Once the ACB is in hand, the appropriate next step — before any significant transaction involving the policy — is to discuss the implications with a qualified CPA who is familiar with the Canadian tax treatment of life insurance. The ACB figure alone does not give the full picture; its interaction with the transaction being contemplated and the policyholder’s overall tax situation determines the consequence.

Frequently Asked Questions
What is the ACB of a life insurance policy?
A tax concept under the Income Tax Act that generally determines the amount receivable from a policy without triggering income. It starts with a figure related to premiums paid and decreases each year as the Net Cost of Pure Insurance (NCPI) is deducted — declining toward zero over time. Not the same as the ACB of shares or real estate.
Why does it decline?
The NCPI — the pure insurance protection cost — is deducted from the ACB each year under the Income Tax Act. As the insured ages, the NCPI generally increases, accelerating the decline. Older policies may have zero or near-zero ACBs.
How does it affect policy loans?
A policy loan is generally not taxable — it’s a loan. But if the outstanding loan exceeds the policy’s ACB, it may trigger a taxable disposition under the Income Tax Act. Check the ACB with the insurer and discuss with a CPA before any significant loan.
How do I find my policy’s ACB?
Contact the insurer directly and request the current ACB. It’s not on standard annual statements. Share it with your CPA before any significant transaction (surrender, policy loan, or other disposition).
