The Alternative Minimum Tax (AMT) has taken on greater effect in recent years, which now presents new legal and tax hurdles for trusts that previously operated with minimal tax friction. Under the current tax regime, the AMT rate has climbed to 20.5%, and the tax base has been broadened by including 100% of capital gains and limiting many deductions to only 50%. A primary strategy for trusts to mitigate this is the intentional retention of income; rather than distributing all net income to beneficiaries to reach a nil tax position under regular rules, trustees may choose to retain enough income to trigger a regular tax liability that equals or exceeds the calculated AMT. This matching approach ensures the trust pays tax at graduated rates (which are often higher for trusts) to satisfy the AMT requirement, thereby avoiding the creation of an AMT credit that might otherwise expire unused after the seven-year carry-forward period.

A second strategy involves restructuring prescribed rate loan arrangements, which have become a major source of AMT exposure due to the new 50% limitation on interest expense deductions. In many family trust setups, the trust pays interest to a lender (like a parent) to invest funds, but under the new rules, half of that interest expense is added back for AMT purposes, often resulting in a tax bill even if the trust distributed all its earnings. To counter this, trustees may consider repaying the principal of the loan or converting the debt into a different asset class that generates more regular income, such as interest or high-yield bonds, rather than capital gains. By shifting the income mix toward non-preferential sources, the trust increases its regular tax liability relative to its AMT liability, effectively neutralizing the AMT hit at the cost of losing the lower tax integration of capital gains.

Charitable giving by trusts also requires a refined tactical approach, as the rules now limit the donation tax credit to 80% and include 30% of capital gains on donated publicly listed securities for AMT purposes. To handle this, a trust might coordinate with a Canadian-controlled private corporation if one is available within the family structure. By having the trust distribute the appreciated securities to a corporate beneficiary, which then makes the donation, the AMT is bypassed entirely because corporations are not subject to the AMT regime. This strategy preserves the full tax-free nature of the capital gain and allows the corporation to add the non-taxable portion of the gain to its Capital Dividend Account, facilitating future tax-free distributions to shareholders.

Implementing these strategies carries significant legal and tax risks, most notably the risk of double taxation and the potential application of the General Anti-Avoidance Rule (GAAR). If a trust pays AMT because it cannot deduct the full amount of its expenses, but the beneficiaries also pay tax on the income allocated to them, the family unit effectively pays tax twice on the same dollar of earnings. Furthermore, if the Canada Revenue Agency (CRA) perceives that a series of transactions (such as a loan repayment followed by a quick re-advance) was designed solely to circumvent the AMT, they could attempt to deny the tax benefits under GAAR. Trustees must ensure that any shifts in investment strategy or distribution patterns are supported by the trust deed and serve a valid non-tax purpose to withstand such scrutiny.

Moreover, the administrative burden of these strategies should not be underestimated, as the trust must now maintain a parallel set of books to track AMT carry-forwards and adjusted taxable income over a rolling seven-year window (more on trust documentation and transparency). There is a high risk of permanent tax loss if a trust triggers AMT in a high-gain year but fails to generate enough regular taxable income in the subsequent seven years to recover the credit. This is particularly problematic for trusts designed to be flow-through vehicles that rarely retain income. Consequently, trustees must engage in proactive multi-year forecasting to determine if a one-time AMT payment is a temporary cash-flow timing issue or a permanent increase in the cost of the trust structure, necessitating a fundamental review of whether the trust remains the most efficient vehicle for the family's wealth.
