How to Use This Calculator

Tab "Contribution Planner"

Enter your annual salary, employer SG rate (default 12%), and any salary sacrifice amount. The calculator shows your total concessional contributions against the $30,000 cap, remaining room, and the tax saving from redirecting income through super (taxed at 15%) instead of your marginal rate. Under "More options," add personal deductible contributions (must lodge a Notice of Intent), non-concessional contributions, and your total super balance to check carry-forward eligibility.

Tab "Contribution Types"

See all the contribution options available to you. Enter your income, spouse income, and total super balance. The calculator shows salary sacrifice room, personal deductible room, non-concessional cap (including bring-forward if eligible), spouse contribution tax offset availability, and government co-contribution eligibility.

Tab "Cap Breach"

Already contributed too much? Enter your total concessional and non-concessional contributions for the year plus your taxable income. See the tax consequences: concessional excess is taxed at your marginal rate (with 15% offset), non-concessional excess at 47%, and Division 293 if income + super exceeds $250K.

The Formulas

Concessional contributions:
Total concessional = Employer SG + Salary sacrifice + Personal deductible contributions
Concessional cap remaining = $30,000 - Total concessional

Tax saving from salary sacrifice:
Saving = (Salary sacrifice + Personal deductible) x (Marginal rate - 15%)

FY 2025-26 tax brackets (Stage 3):
$0 - $18,200: 0%
$18,201 - $45,000: 16%
$45,001 - $135,000: 30%
$135,001 - $190,000: 37%
$190,001+: 45%

Concessional excess tax:
Excess x Marginal rate - (Excess x 15% offset) = Net additional tax

Non-concessional excess:
Excess x 47% (top marginal + Medicare) โ€” or elect to withdraw

Division 293:
If (Income + Concessional contributions) > $250,000:
Tax = min(Concessional contributions, Excess above $250K) x 15%

Bring-forward NCC thresholds (TSB at prior 30 June):
Under $1.66M: 3 years ($360K)
$1.66M - $1.78M: 2 years ($240K)
$1.78M - $1.90M: 1 year ($120K)
Over $1.90M: nil

All figures based on ATO rates for FY 2025-26. Super contributions are taxed at 15% inside the fund (Division 293 adds another 15% for high earners). Carry-forward applies to unused concessional caps from FY 2018-19 onwards, available only if TSB was under $500,000 on the previous 30 June.

Example

James โ€” Software Engineer in Sydney, Salary $120,000

Employer SG at 12% = $14,400. Salary sacrifice $10,000. Personal deductible contribution $5,000. TSB at 30 June 2025: $200,000.

Total concessional contributions$29,400
Concessional cap remaining$600
Tax saving (sacrifice + personal deductible)$2,250
Division 293 check$120K + $29.4K = $149,400 โ€” under $250K threshold
Carry-forward eligible?Yes โ€” TSB $200K is under $500K

James's $10,000 salary sacrifice and $5,000 personal deductible contribution save him $2,250 in tax because the money is taxed at 15% inside super instead of his 30% marginal rate. He has $600 of cap remaining and could use carry-forward to contribute more if he has unused caps from prior years.

Frequently Asked Questions

Concessional contributions include employer SG contributions, salary sacrifice contributions, and personal contributions for which you claim a tax deduction (by lodging a Notice of Intent with your super fund). All three types share the same $30,000 annual cap. Concessional contributions are taxed at 15% inside your super fund, which is lower than most people's marginal tax rate.
If your total super balance (TSB) was under $500,000 on 30 June of the previous financial year, you can carry forward unused concessional cap amounts from up to 5 prior financial years (starting from FY 2018-19). For example, if you only used $20,000 of your $30,000 cap last year, you have an extra $10,000 available this year, giving you a $40,000 effective cap. This is especially useful for making a larger one-off contribution, such as from a bonus or asset sale.
Excess concessional contributions are added to your assessable income and taxed at your marginal tax rate. You receive a 15% tax offset because the fund already paid 15% contributions tax. You can elect to release up to 85% of the excess from your super fund to help pay the additional tax. The ATO will issue an excess concessional contributions determination after you lodge your tax return.
Yes. To claim a tax deduction for personal super contributions, you must lodge a valid Notice of Intent to claim a deduction (section 290-170 ITAA 1997) with your super fund, and receive an acknowledgement, before you lodge your tax return or rollover the contribution. If you don't lodge the notice in time, the contribution is treated as non-concessional and cannot be claimed as a deduction.
If you are under 75 (previously 67) and your total super balance is under $1.66 million on the previous 30 June, you can trigger the bring-forward rule by contributing more than $120,000 in non-concessional contributions in a single year. This gives you access to up to 3 years of NCC caps ($360,000) upfront. The available amount depends on your TSB: under $1.66M = $360K (3 years), $1.66M-$1.78M = $240K (2 years), $1.78M-$1.90M = $120K (1 year), over $1.90M = nil.
