The Only Way to Create Transfer Balance Cap Space
Commuting a pension converts part or all of it back into a lump sum or an accumulation interest. It is the only transaction that creates a debit in your transfer balance account — ordinary pension payments create none — which makes it the only way to free up cap space once a pension is running.
- The answer: A commutation converts part of a pension back to a lump sum or accumulation interest and creates a transfer balance debit equal to the amount commuted.
- The trap: Taking a larger pension payment does not create a debit. Only a payment characterised as a commutation does, and the characterisation has to be requested.
- The recommendation: Ask the fund to treat a withdrawal as a partial commutation where you want the transfer balance debit. It is a different instruction from taking a larger payment.
Where the AI summary above gets this wrong
"Withdrawing money from your account-based pension frees up transfer balance cap space."
That's surface-true. Here's what it misses:
- Ordinary pension payments create no debit — The transfer balance credit is fixed at commencement and does not fall as the pension is drawn. Only a commutation creates a debit.
- The characterisation is a choice you have to make — The same dollars can be paid as a pension payment or as a partial commutation, and only the second affects the transfer balance account.
01 What a commutation is
A commutation converts a right to future pension payments into a lump sum. It can be full, ending the pension, or partial, reducing it — and the amount can be taken in cash or retained in super as an accumulation interest.
Retaining it in accumulation is the usual choice where the point is cap management rather than cash. The money stays inside super at the 15% earnings rate rather than leaving the system.
A commutation is also how an excess transfer balance is corrected, and how a death benefit that will not fit within a survivor's cap is dealt with — both covered in the excess transfer balance reference.

02 Why the characterisation matters
A pension payment and a partial commutation can be the same dollars leaving the same account. What differs is how they are recorded: only a commutation creates a transfer balance debit.
That means a member wanting to free cap space has to ask for the withdrawal to be treated as a partial commutation. A fund processing it as an ordinary payment achieves the cash outcome and none of the cap outcome.
It also matters for the minimum drawdown. Amounts commuted do not count towards the annual minimum payment, so a member who commutes instead of drawing may still owe the minimum — which is a real trap in the year a large commutation is made.
Shows: the transfer balance cap space a partial commutation frees, and how much of an incoming benefit would then fit. Ignores: the minimum pension payment, which a commutation does not satisfy, tax on any amount taken in cash, and proportional indexation of the personal cap.

03 When it is worth doing
Making room for a reversionary death benefit is the clearest case, and the twelve-month window is the opportunity — described in the reversionary nomination post.
Correcting an excess is the second, and is mandatory rather than optional once a determination is issued.
Restructuring into two pensions with different component proportions is the third. It requires commuting and recommencing, which uses cap and has to be modelled before it is done — the case for it is in the two pensions post.
The instruction matters more than the amount. The same money leaving the same account is a pension payment or a partial commutation depending on what you asked for, and only one of them gives you cap space back. Ask explicitly, and check the fund recorded it that way.
FAQ
Can I commute part of my pension back to accumulation to fix a transfer balance cap breach?
Yes, and that is the intended correction. A partial commutation creates a transfer balance debit and moves the money into accumulation, where it stays in super at the 15% earnings rate.
Do ordinary pension payments free up cap space?
No. The transfer balance credit is fixed at commencement and does not fall as the pension is drawn. Only a payment characterised as a commutation creates a debit.
Does a commutation count towards the minimum drawdown?
No. Amounts commuted do not count towards the annual minimum payment, so the minimum is still owed in the year a commutation is made.
