COMPLIANCE
When Two Defined Benefit Pensions Meet: Transfer Balance Cap Implications for Reversionary Beneficiaries
When a spouse becomes the reversionary beneficiary of a Commonwealth defined benefit pension, the combined impact on their Transfer Balance Account can be significant and largely unavoidable. Here is what advisers and trustees need to understand.
Overview
What this guide covers
CSS, PSS, and MSBS pensions are non-commutable lifetime income streams. When a surviving spouse holds one of these pensions and then inherits a reversionary defined benefit pension from a deceased partner, the combined special values can push their Transfer Balance Account into excess — with no structural way to fix it. This guide explains the mechanics, the two separate tax consequences that follow, and what advisers must document in their advice.
KEY TAKEAWAYS
What you will learn
✔ How CSS, PSS and MSBS pensions are valued for Transfer Balance Cap purposes using the Special Value formula (annual pension × 16)
✔ Why the 12-month TBA credit deferral is a critical planning window and why any commutable income streams must be actioned before that window closes
✔ Why the normal remedy, commuting the excess back to accumulation is simply not available for defined benefit pensions
✔ The two separate tax consequences: excess transfer balance earnings tax (15% or 30%) and the Defined Benefit Income Cap impact
✔ Why Centrelink assesses the reversionary pension as income from day one, not from the 12-month TBA credit date
✔ The full documentation checklist for advisers preparing a Statement of Advice in this situation
THE CRITICAL PLANNING WINDOW
12 months to act and why it matters
When a reversionary pension transfers to a surviving spouse, the TBA credit is deferred for 12 months from the date the pension first becomes payable. The surviving spouse receives the pension income immediately, but the credit to their Transfer Balance Account does not register until that 12-month mark. This window is the only structural opportunity to reduce the impact — by commuting any account-based pensions or other commutable income streams the surviving spouse holds before the credit date arrives.
Important: Once the 12-month window closes and both defined benefit pensions are credited to the Transfer Balance Account, the excess cannot be structurally resolved. CSS, PSS, and MSBS pensions are non-commutable under SIS Regulation 6.17A — the ATO's standard commutation authority pathway simply does not apply. The result is an ongoing tax penalty with no ability to remedy the structural excess.
Two separate tax consequences
What the excess actually costs
Surviving spouses in this position face two distinct and ongoing tax impacts that compound over time. The first is excess transfer balance earnings tax — notional earnings on the excess amount are calculated using the Shortfall Interest Charge rate and taxed at 15% on a first breach, rising to 30% on subsequent breaches. The second is the Defined Benefit Income Cap: combined CDBIS income above $131,250 per year loses the 10% tax offset that would otherwise apply, resulting in that excess being taxed at the full marginal rate. Both impacts are permanent for as long as both pensions continue.
