Division 296: What SMSF Trustees Need to Know About Earnings Attribution and Valuation

The Division 296 superannuation tax framework is now supported by detailed regulations that set out how earnings are attributed to members and how superannuation interests are valued.

For SMSFs, these rules directly affect how Total Superannuation Balance (TSB) and Division 296 taxable earnings are calculated from 19 June 2026.

The regulations do not change the tax rate itself. They define the calculation methodology.

Overview of the Division 296 regulations

The Income Tax Assessment (1997 Act) Amendment (Building a Stronger and Fairer Super System and Other Measures) Regulations 2026 provide the technical framework for:

• attribution of earnings to individual members
• valuation of superannuation interests
• adjustments for family law payment splits
• updated actuarial assumptions for defined benefit calculations

These rules apply across SMSFs and large superannuation funds to ensure consistency in reporting and taxation outcomes.

Schedule 1: Earnings attribution rules

Schedule 1 sets out how investment earnings are allocated between members of a superannuation fund.

For SMSFs, this is particularly relevant where members have unequal balances or different investment strategies.

The key principle is that earnings must be attributed in line with each member’s actual economic interest in the fund, rather than a simplified equal split.

Where assets are segregated, earnings are attributed based on the performance of those specific assets.

Schedule 2: Valuation of superannuation interests

Schedule 2 prescribes how different types of superannuation interests must be valued, including:

• accumulation accounts
• pension accounts
• defined benefit interests
• other structured superannuation entitlements

These valuation rules ensure consistent calculation of Total Superannuation Balance (TSB), which is central to determining Division 296 exposure.

Schedule 3: Family law adjustments

Where superannuation interests have been split under family law arrangements, Schedule 3 ensures each member’s TSB reflects the correct post-split entitlement.

This prevents double counting or distortion of balances following a separation.

Schedule 4: Updated actuarial assumptions

Schedule 4 updates assumptions used in:

• notional taxed contributions
• defined benefit valuation models
• contribution calculation methodologies

These updates align valuation assumptions with current economic and demographic conditions.

Example: SMSF administered by iCare Super

An SMSF administered by iCare Super has two members.

Fund structure

• Member A (Alex): $3.6 million
• Member B (Taylor): $900,000
• Total fund balance: $4.5 million

Fund performance

• Investment earnings for the year: $360,000
• No contributions or withdrawals

Step 1: Member ownership proportions

• Alex: 80%
• Taylor: 20%

Step 2: Earnings attribution

• Alex: $360,000 × 80% = $288,000
• Taylor: $360,000 × 20% = $72,000

Step 3: Apply Division 296 threshold

Only balances above $3 million are relevant.

• Alex excess: $3.6m − $3.0m = $600,000
• Excess proportion: 16.67%

Step 4: Taxable earnings

• $288,000 × 16.67% = $48,000

Step 5: Division 296 tax

• $48,000 × 15% = $7,200 tax liability

Taylor is not impacted as their balance is below the threshold.

Key takeaway

The Division 296 regulations provide the detailed calculation framework behind the new tax system. For SMSFs, the most important impact is not the tax rate itself, but how earnings and balances are measured and attributed.

Accurate administration and valuation processes will be essential for compliance and planning as the new rules take effect.
