Hong KongDrawing income in retirement: order, rate and flexibility
The conventional order is taxable, then tax-deferred, then Roth. Managing the tax bracket across years usually beats it. The 4 per cent rule is a research finding about a historical period, not a planning guarantee.
Two decisions: how much, and from where. The second gets less attention and is more controllable.
The conventional order
Taxable first, then tax-deferred, then Roth.
The reasoning is that it maximizes the time tax-advantaged accounts keep compounding, and it uses the step-up in basis on any taxable assets remaining at death.
Why bracket management usually beats it
Emptying the taxable account first leaves a client with very low income for several years, then a large jump when required distributions begin.
That wastes the low brackets in the early years and pays high rates later. Drawing proportionally, or filling a bracket each year with tax-deferred withdrawals and Roth conversions, produces a lower lifetime tax bill.
Where one option recites the conventional order and another describes managing the bracket across years, the second is generally correct. The conventional order is a starting point, not the recommendation.
The 4 per cent rule
Withdraw 4 per cent of the initial portfolio in year one, then increase that dollar amount with inflation.
It came from research on historical US returns over thirty-year periods with a specific allocation. It is a finding about that data, not a law, and it is not advice.
- It assumes a thirty-year horizon. A client retiring at 55 needs longer.
- It ignores taxes and fees.
- It assumes a fixed real spending pattern, which is not how people spend.
- It is based on a period that may not repeat.
- It leaves a large residual balance in most scenarios, which is inefficient if there is no bequest motive.
The exam expects you to know what it is and to know that presenting it as a guarantee is wrong.
Dynamic approaches
Guardrails: adjust spending up or down when the withdrawal rate drifts outside a band. Floor and ceiling: vary spending within limits. Required distribution method: recalculate each year from the current balance.
All of them trade certainty of income for certainty of not running out, and a client who can flex spending in a bad year can safely start at a higher rate.
The bucket approach
Cash for the next two to three years, bonds for the following several, equities for the long term. Refill the near buckets from the far ones in good years.
Whether it improves outcomes over a simple rebalanced portfolio is debated. What is clear is that it helps clients stay invested during a downturn, because they can see where the next few years of income is coming from - and that behavioral benefit is real.
Dollar limits here are indexed annually and the transfer tax exclusion was changed by the 2025 reconciliation act. Confirm the current figure before relying on it.
Common questions
What is the conventional withdrawal order?
Taxable, then tax-deferred, then Roth. It maximizes compounding in tax-advantaged accounts and preserves the step-up in basis on remaining taxable assets.
Why is bracket management better?
Emptying the taxable account first wastes the low brackets in early retirement and produces a jump when required distributions begin. Filling a bracket each year lowers the lifetime tax bill.
What is the 4 per cent rule?
Withdrawing 4 per cent of the initial portfolio and increasing that dollar amount with inflation. It is a finding from research on historical US returns over thirty years, not a guarantee.
What are the limits of the 4 per cent rule?
It assumes a thirty-year horizon, ignores taxes and fees, assumes fixed real spending, rests on one historical period, and usually leaves a large residual balance.
Does the bucket approach improve outcomes?
The financial benefit over a rebalanced portfolio is debated. The behavioral benefit is real - clients can see where the next few years of income comes from and are more likely to stay invested.
