Which money should you spend first?

The common rule of thumb

Many plans start with taxable accounts, then pre-tax retirement accounts, then Roth. The logic is simple: spend the account that creates only capital-gains tax first, let tax-deferred money keep growing, and preserve Roth as the most flexible bucket.

That can be a perfectly reasonable default. It is not a law of nature.

Why the default can be wrong

Low-income years can be valuable. If you retire before Social Security, pension income, or RMDs begin, drawing or converting some pre-tax money may fill a lower bracket on purpose. Waiting can push more income into later single-filer years, larger RMDs, or higher Medicare premiums.

Taxable sales have their own traps. Selling appreciated investments can create long-term capital gains, restack against ordinary income, and potentially trigger NIIT. Roth withdrawals are often useful precisely because they can fund a large need without raising taxable income or IRMAA.

Early access is account-specific

Before 59½, access depends on the account, the employer plan, the job separation date, whether dollars are contributions, conversions, or earnings, and whether a penalty exception applies. It is not a universal lockout, and it is not a universal open door.

The Rule of 55 is tied to the current employer plan from the job you left: the exception generally covers distributions from that qualified plan after you separate from service in or after the year you turn 55. Rolling that money to an IRA can change access, and certain public-safety rules use different ages.

Section 72(t) substantially equal periodic payments can avoid the 10% additional tax, but they are rigid and long-running, generally lasting until the later of five years or age 59½. They are not a casual or automatic switch.

Roth IRAs have layers. Contributions, conversions, and earnings sit in different layers with different tax and penalty rules, so “Roth” does not mean every dollar is equally accessible.

What RetireRebel compares

The model keeps the old taxable-first path as the saved-plan default, then lets the Optimizer evaluate policy alternatives. A bracket-aware path can spend taxable assets while intentionally converting or drawing pre-tax assets up to a tax target. A tax-aware review path looks for years where Roth dollars are valuable because they avoid a tax or Medicare threshold.

These are model comparisons, not individualized instructions. RetireRebel does not decide which early-access exception applies to your plan documents or Roth basis records. Before acting on a large withdrawal or conversion, confirm the tax treatment with a CPA or fiduciary who can see the account details RetireRebel does not have.
