What it means
Think of a Roth account as a bucket with three layers: money you put in directly, money you converted from another retirement account, and the profit earned on both. When you withdraw, you do not get to choose the layer.
The tax rules treat the withdrawal as coming from the layers in a fixed sequence, and that sequence generally favours the saver. The usual sequence is contributions first, then conversions, then earnings.
Contributions were made with money that had already been taxed, so taking them back out is generally free of tax and penalty. Conversions come next, oldest first, and have already been taxed at the time of conversion, although an early-withdrawal penalty may apply if they are taken out too soon.
Earnings come last and are the layer most exposed to tax and penalty if the withdrawal is not a qualifying one. The practical benefit is that you can often reach your own contributions in an emergency without a tax bill.
That is why advisers describe the contributions layer as the flexible part of a Roth account, even though the account is meant for retirement. The tax authority sets the exact age, holding period and penalty terms, and they can change, so it is wise to check the current rules before acting.
More broadly, the phrase "ordering rules" is also used in other places where the sequence of treatment matters, such as which shares are deemed sold first for tax purposes or which payments are applied first against a debt. In each case the rule is the same idea: when a pool is mixed, a fixed order tells you what came out.
If you hear the phrase in a meeting, ask which pool and which sequence is being discussed.
In practice
Real-world examples.
Example
A freelance designer has put $24,000 into a Roth account over four years and needs $10,000 for an unexpected tax bill. Because contributions come out first, the whole $10,000 is treated as a return of her own contributions. She pays no tax or penalty on it.
Example
A manager converts $50,000 from a traditional retirement account to a Roth account and, a year later, needs $20,000. The ordering rules treat the withdrawal as coming from conversions if no contributions remain. He avoids a second round of income tax but needs to check whether an early-withdrawal penalty applies.
Example
A couple's adviser maps out their Roth account before retirement, listing contributions, conversions and earnings separately. This lets the couple plan which pool to draw from first and keep taxable income low in the years they stop working.
Formula
Calculation
Order of withdrawal from a Roth account: 1) contributions, 2) conversions (oldest first), 3) earnings
An investor has a Roth account holding $30,000 of contributions, $20,000 of conversions and $10,000 of earnings, giving a balance of $60,000. She withdraws $35,000 before meeting the conditions for a fully qualifying withdrawal. The first $30,000 comes from contributions and is not taxed or penalised, and the remaining $35,000 - $30,000 = $5,000 comes from conversions, which are not taxed again but may attract an early-withdrawal penalty. The $10,000 of earnings is untouched, and the account is left with $60,000 - $35,000 = $25,000.Case study
Seen in the real world.
Linden & Rowe Advisory is a fictional planning firm used here as an illustrative example. A client, aged in her late forties, asked whether she could use her Roth account to fund a deposit on a rental property worth $400,000.
The adviser built a one-page schedule showing $42,000 of contributions, $18,000 of conversions and $15,000 of earnings. Under the ordering rules, the first $42,000 of any withdrawal would be treated as her own contributions and could be taken without tax or penalty.
The client needed $40,000 for the deposit, so the whole amount came from the contributions layer. The illustrative lesson is that the same $75,000 balance can have very different tax consequences depending on what sits inside it, and that keeping records of each layer is essential.
Watch out
Common mistakes.
- Assuming you can choose to withdraw earnings first or last, when the rules decide the order automatically.
- Throwing away records of past contributions and conversions, when those records are the evidence needed to prove which layer a withdrawal came from.
- Treating all money in a Roth account as equally accessible, when conversions and earnings can carry penalties or tax that contributions do not.
Questions
People also ask.
Do the ordering rules apply to traditional retirement accounts?
Not in the same way, because traditional accounts are generally taxed on withdrawal as a whole, so there is less need to sort the money into layers.
Which conversion is treated as withdrawn first?
The oldest conversion comes out first, which is useful because older conversions are more likely to have passed any holding period.
Where should I check the current rules?
The tax authority's published guidance is the safest source, because ages, holding periods and penalty terms are set by law and can change.
