Alternative Minimum Tax: Plan Before the Gain Is Realized
A client who paid AMT in 2024 and whose profile hasn't changed pays it again in 2025, with the carryforward growing instead of reversing. Work through the 100% capital gains inclusion, the 50% limits on interest expense and loss carryovers, the trust exposure, and the Holdco and year-of-death routes out.
Alternative Minimum Tax: Capital Gains, Interest Expense, Public Company Share Donations, and Recovering the AMT Carryforward
The disposition closes, and the AMT appears when the return is prepared. By then every structural option has expired: the rollover to a holding company, the mortgage take-back that spreads the gain, the loss realized into the same year. What is left is a carryforward, and a client whose profile has not changed.
The carryforward reverses only against income taxed above 20.5% federally. Ordinary income absorbs it quickly, non-eligible dividends slowly, eligible dividends barely at all, and another capital gain adds to it. Where the profile that produced the AMT continues unchanged, the balance grows year over year.
- check_circle Capital gains at 100% in the AMT base. The move from 80% to full inclusion, the 30% inclusion where the capital gains exemption is claimed, and the effective capital gains rate this produces once provincial AMT is layered on.
- check_circle Interest expense and loss carryovers at 50%. Interest incurred to earn property income against interest to earn business income, net capital loss and non-capital loss claims, and why an ABIL routed through a non-capital loss carryover is effectively allowed at 25%.
- check_circle The $177,882 exemption and the 20.5% rate. Indexation, the nil exemption for trusts, and why raising the AMT rate from 15% narrows the differential against regular tax and makes the carryforward harder to recover.
- check_circle Donations of public company shares. Gain inclusion at 30% where the regular calculation reports none, the donation credit allowed at 80%, and the resulting effective federal credit rate of 26.4%.
- check_circle Inter vivos trusts and the nil exemption. Why capital gains combined with prescribed rate loan or margin interest is the profile most exposed to AMT, the grossed-up deduction on distributed gains, and why the carryforward is particularly difficult for a trust to recover.
- check_circle Provincial AMT and the year of death exemption. Piggyback rates applied to federal AMT payable, the Ontario surtax interaction, Quebec's separate calculation, and the terminal return, GRE and elective return exemptions the planning turns on.
What You'll Learn
Ten modules, in the order the seminar builds them. The calculation and the base adjustments first, then the client profiles that trigger AMT, then the seven mitigation strategies and the structures used to execute them.
expand_more The AMT Calculation: Adjusted Taxable Income, the $177,882 Exemption, and the 20.5% Rate
A separate calculation run alongside regular tax, and the four variables that decide the outcome.
- The mechanics AMT computed separately, compared to regular tax, the excess payable, and a carryover recoverable in a year when AMT falls below regular tax.
- The formula Adjusted taxable income less the exemption, multiplied by the minimum tax rate, less adjusted tax credits.
- The exemption $177,882 for 2025, indexed annually, increased from $40,000, and why it eliminates AMT entirely for most taxpayers.
- How the exemption was set Its relationship to the federal brackets and the average federal rate at that level of ordinary income.
- The rate Increased from 15% to 20.5% federally, compressing the gap between regular tax and AMT.
- Two consequences of the higher rate More profiles fall into AMT, and recovery of an existing carryforward becomes materially harder.
- Trusts No exemption available other than for a qualified disability trust.
- The 2024 experience Why a client who paid AMT in 2024 and whose profile is unchanged will pay again, with the balance compounding rather than reversing.
expand_more AMT Base Inclusions: Capital Gains at 100%, the Stock Option Deduction at Nil, and the Loss Asymmetry
Item by item against the pre-2024 rules, with the material changes identified.
- Capital gains Inclusion moved from 80% to 100%, against 50% for regular tax purposes.
- Capital gains where the CGE is claimed Inclusion held at 30%, unchanged from the old system.
- Capital gains on a public company share donation Inclusion at 30% where the regular calculation reports nil, a new addition under the current rules.
- Net capital loss claims Moved from 8/5 of the claim to the actual amount, meaning only 50% of the underlying capital loss.
- The asymmetry this creates 100% of the gain in, 50% of the loss out, where the loss arrives as a carryover rather than in the same year.
- Allowable business investment losses Moved from 8/5 to actual.
- The stock option deduction Previously allowed at 2/5, now allowed at nil for AMT despite the 50% deduction for regular tax.
expand_more AMT Base Deductions at 50%: Interest Expense, Non-Capital Loss Carryovers, and the Minor Adjustments
A long list of restrictions, two of which matter and the rest of which do not.
- Interest and financing expense to earn property income Allowed at 50%, and why interest incurred to earn business income is not subject to the adjustment.
- Non-capital loss carryovers Allowed at 50% of the amount claimed for regular tax purposes.
- The ABIL compounding problem Only half the business investment loss becomes an ABIL, and where that ABIL becomes part of a non-capital loss carryover, only half of that is allowed for AMT.
- Limited partnership losses of other years Allowed at 50%.
- Unchanged at nil Tax shelter losses, CCA, and the interest and carrying charges already denied under the old system.
- Reduced from 100% to 50% Employee expenses other than commission expenses, the CPP deduction, moving expenses, child care expenses, the northern residents deduction, and the armed forces and police deduction.
- Which of these to ignore Why the large number of 50% adjustments will not, for most clients, produce a material outcome.
expand_more AMT Tax Credits and Provincial AMT: The 80% Donation Credit and the Piggyback Rates
Where the federal number is set, and how much each province adds on top of it.
- Personal tax credits Allowed at 50% for AMT purposes.
- The donation tax credit Allowed at 80%, producing an effective federal credit rate of 26.4% against 33% under the regular calculation.
- The foreign tax credit A separate calculation for AMT with no percentage reduction, and why it will not generally cause AMT on its own.
- Provincial AMT Calculated as a percentage of federal AMT payable rather than on a separate provincial base.
- Ontario The provincial AMT rate combined with the surtax to produce the percentage applied to federal AMT.
- The provincial range Three bands across the country: the low-to-high 30s, the 42% to 45% range, and the 50% to 57.5% group.
- Quebec Its own AMT calculation compared against its own regular tax, not directly comparable to the other provinces.
- The combined result on a large capital gain Effective rates province by province, and the implied capital gains inclusion rate this amounts to for a top-rate individual.
expand_more The Rate Differential by Income Type and the August 2024 Proposed Amendments
The differential table that tells you whether a client's AMT is recoverable, plus two proposals not yet law.
- Income taxed above the AMT rate Business, employment and property income at the top federal rate against 20.5%, and the spread that absorbs AMT.
- Dividends The much smaller differential on non-eligible dividends, and the near-zero differential on eligible dividends.
- Income taxed below the AMT rate Capital gains and stock option benefits with the deduction, both negative, both adding to AMT rather than absorbing it.
- The deduction side Differentials on interest and financing expense, non-capital loss carryovers, net capital loss carryovers, donations, and gains on public company share donations.
- How much offsetting income is required The ratio of ordinary income, non-eligible dividends and eligible dividends needed to eliminate AMT on a gain, and why the eligible dividend answer makes recovery impractical.
- Flow-through shares The proposed carve-out from the capital gains adjustment.
- Investment counsel fees The proposal to allow only 50%, the retroactivity problem given filed 2024 returns and software that never reflected it, and its status as not yet law.
expand_more Tax Profiles Sensitive to AMT: Real Estate Dispositions, Opco Share Sales, Stock Option Benefits, and Emigration
Run this list before a transaction closes.
- Large capital gains Dispositions of real estate, sale of Opco shares by an individual, sale of a public share portfolio, gains realized and retained in a trust, and the deemed disposition on emigration.
- The death exception Why the deemed disposition on death does not attract AMT.
- Stock option benefits with the 50% deduction Taxed at a rate equivalent to a capital gain for regular purposes, no deduction for AMT, benefit recognized on sale for CCPC shares and on exercise otherwise.
- Why stock options are a recurring problem A one-time realization event with no offsetting high-rate income in the year.
- Interest and financing expenses Property income borrowing generally, and prescribed rate loans in particular.
- Loss carryover utilization Net capital and non-capital losses applied in a year with gains.
- Public company share donations Large accrued gains combined with a large credit claim.
- Inter vivos trusts Capital gains plus interest expense, arising through a margin account against the portfolio or a prescribed rate loan used to fund the trust.
- Bad combinations Why gains and restricted deductions appearing together exacerbate the result rather than merely adding to it.
expand_more Seven Strategies to Mitigate AMT: Managing Income, Timing Gains and Losses, and Spreading a Gain
The planning framework, and the decisions that can still be made at the time the return is prepared.
- Managing income Keeping adjusted taxable income within reach of the exemption, and the sheltering effect the exemption provides on gains, interest expense and loss claims.
- Timing gains and losses Realizing gains and losses in the same year rather than carrying a net capital loss forward or back, and monitoring the year-to-date position to do it.
- The return-preparation decision Choosing how much net capital loss carryover to apply, which remains open after year end.
- Spreading a gain Taking back a mortgage to spread a capital gain across five years, keeping each year within reach of the exemption, with the interest earned on the mortgage itself absorbing AMT.
- Reducing interest expense Paying down loans to limit the 50% disallowance.
- Managing donations Staging public company share gifts across years to keep the AMT gain inclusion below the exemption, and the adverse consequence for the charity.
- Non-capital losses and ABILs Creating regular income in the following year to recover, including an RRSP withdrawal, and switching an owner-manager from dividends to salary.
- Using a corporation Earning investment income and capital gains corporately, particularly where deductible interest expense is present.
- Death and the GRE The exemptions available in the year of death and in a graduated rate estate.
- Avoiding bad combinations Keeping a large gain and a restricted deduction out of the same year, since together they compound the result rather than add to it.
expand_more Using a Holding Corporation: Capital Dividends, TOSI, the Flipped Property Rules, and the SBD Grind
The structural answer that takes the gain out of the individual's base, and the four costs that come with it.
- Sale of a business through Holdco Rolling Opco shares to a holding company on a tax-deferred basis before the sale, with the gain realized corporately.
- Distribution mix Capital dividend for the non-taxable half and non-eligible dividend for the balance, against retaining the taxable portion in Holdco.
- Why the non-eligible dividend helps twice It is taxed above the AMT rate, so it shelters AMT at the personal level as well as removing the gain from the individual's base.
- The blended approach Selling part of the holding personally and part through Holdco so the taxable dividend soaks up the personal AMT.
- Comparing the four outcomes Full retention in Holdco, full distribution from Holdco, a personal gain without AMT, and a personal gain with AMT.
- The integration cost Provinces where the fully integrated rate on corporate passive income exceeds the personal rate, and what that costs on a capital gain.
- Investment portfolios Transferring the portfolio and the associated loan to Holdco, and the ACB condition that has to hold for the loan to be assumed.
- The flipped property trap Residential real estate transferred to a corporation and sold within one year of the transfer.
- The remaining costs TOSI blocking income splitting, association and the small business deduction grind on passive income, and the additional filing and accounting burden.
expand_more Trusts and AMT: The Nil Exemption, the Grossed-Up Distribution Deduction, and the QDT Exception
The one taxpayer with no exemption, and the hardest carryforward to recover.
- No exemption Trusts receive nil, other than a qualified disability trust.
- The relieving rule A taxable capital gain distributed to beneficiaries is deducted from the AMT base at the grossed-up 100% amount.
- Why AMT survives a full distribution Expenses that are not fully deductible for AMT leave residual income in the base even where all income is paid out.
- The recovery problem Why the carryforward mechanism is close to unusable for a trust, which cannot generate high-rate income the way an individual can take a bonus.
- Transferring the portfolio and loan to Holdco The pros and cons, including TOSI, the flipped property rules, a possible SBD grind, and additional filings.
- Declining to claim the interest expense Weighing the beneficiaries' tax positions against the trust's AMT, and the open question of whether a trust can allocate income exceeding its economic income.
- Altering the portfolio Shifting toward fixed income so the AMT-sensitive gains do not arise to the same extent.
- Selling investments to retire the loan Removing the interest expense side of the combination entirely.
- Distributing to beneficiaries Distributing the gains or the portfolio itself so that individual beneficiaries, each with an exemption, earn the income and potentially assume the loan.
expand_more Donations, Stock Option Exercises, Rental Income Recharacterization, and the Spousal Rollover Election
Four specific interventions, including the one that has to be made in the will rather than on the return.
- Public company share donations The combination of a 30% AMT gain inclusion and a donation credit at 80%, producing AMT for a donor whose regular tax is nil.
- Staging donations Sizing an annual gift so the AMT gain inclusion is absorbed by the exemption and the credit, and the cost to the charity of doing so.
- Donating on death or by will Why the year of death and the graduated rate estate remove AMT from the analysis, and what this changes about a long-standing giving pattern.
- Stock option exercises Splitting an exercise across two calendar years so two annual exemptions are available against a benefit that carries no AMT deduction.
- Property income against business income Why the 50% interest restriction applies only to borrowing to earn property income.
- Recharacterizing a rental operation Business name, separate bank account, website and level of activity, the position that the interest is then business interest, and the circumstances in which the position will not hold.
- Spousal rollover on death Where the beneficiary spouse will sell shortly, electing out so the gain is realized on the terminal return, which is exempt from AMT.
- What electing out costs Tax paid sooner in exchange for lower tax overall.
- The GRE alternative Selling within the 36-month graduated rate estate window instead.
- The full exemption list The terminal T1, rights and things and other elective returns, the deemed disposition in an alter ego, spousal or joint spousal trust on the relevant death, and the GRE.
