A tax-efficient retirement income plan is built in a specific order: identify predictable income first, calculate the shortfall against actual spending, then decide which account types fund that shortfall each year — with future required distributions planned for from the start.
Retirement income planning is less complicated than it appears, provided the steps happen in the right order. Most plans go wrong by starting with the portfolio instead of ending with it.
Here is the sequence we use.
Start with the income floor
Before the portfolio does anything, establish what arrives regardless: Social Security, any pension, and any other contractual income. This is your income floor.
The size and shape of that floor changes everything downstream. A household with a substantial pension needs the portfolio to take considerably less risk than a household without one, and that fact alone often reshapes the allocation.
Calculate the actual shortfall
Subtract the guaranteed income from what you genuinely spend — not a rule of thumb, not a percentage of your final salary. Real spending, including the irregular items people leave out: the car every several years, the roof, the trip, the help you intend to give.
The remainder is the number the portfolio has to produce. Everything from here is about producing it in the most tax-efficient way available.
Know what each account type does to your tax bill
Taxable accounts generate income only on gains and dividends, and gains receive preferential rates — which means a withdrawal often adds much less to taxable income than its size suggests.
Tax-deferred accounts — traditional IRAs and 401(k)s — are fully taxable as ordinary income on withdrawal, and are the accounts that eventually force required minimum distributions. Roth accounts, having already been taxed, generally come out tax-free and do not add to the calculations that determine Medicare surcharges or how much of your Social Security is taxable.
Having all three is what makes the plan flexible. Each year you can decide where the money comes from based on what your bracket, your conversion plan, and your insurance situation call for.
Plan for required distributions before they arrive
Required minimum distributions are the most predictable tax event in retirement and the most commonly ignored. A large tax-deferred balance eventually forces income whether or not you need it, and it can put a household into a higher bracket in retirement than during their working years.
The years to address that are the ones before RMDs begin — drawing from tax-deferred accounts earlier than instinct suggests, or converting to Roth up to the top of a target bracket, deliberately reducing the balance that will eventually be forced out. Once distributions start, the room to manoeuvre shrinks considerably.
The word bulletproof is doing some work here — no plan is immune to markets or to legislative change. What a well-built plan aims to do is remove the avoidable failures: no unmanaged tax exposure, no forced selling at a bad moment, and no year where the withdrawal decision is made without knowing what it costs.
