Personal Super Contribution Deduction Calculator

Work out your tax saving from claiming a personal super contribution as a deduction. The calculator checks your base and carry-forward concessional cap, applies 15% contributions tax and Division 293 where relevant, and compares claiming the deduction against leaving the amount as non-concessional to pursue the government co-contribution. It also surfaces the Notice of Intent deadline — a commonly missed trap.

Net benefit by marginal rate (2026-27)

The table below shows the net benefit of claiming a $10,000 deduction at each 2026-27 marginal rate bracket. Fund tax (15%) is fixed; income tax saved varies with your marginal rate and includes the 2% Medicare levy. Assumes no prior concessional contributions — full $32,500 cap available.

Income (example) Bracket range Marginal rate Tax saved Fund tax (15%) Net benefit
$45,000 $18,201–$45,000 15% $1,700 $1,500 $200
$90,000 $45,001–$135,000 30% $3,200 $1,500 $1,700
$160,000 $135,001–$190,000 37% $3,900 $1,500 $2,400
$220,000 $190,001+ 45% $4,700 $1,500 $3,200

Bracket boundaries and rates from 2026-27 config. Division 293 does not apply at these income levels. Net benefit = income tax saved (incl. Medicare) minus 15% contributions tax.

Division 293 — above $250,000

Division 293 imposes an extra 15% tax on concessional contributions when your Division 293 income (taxable income after the deduction plus all concessional contributions for the year) exceeds $250,000. The effective fund-side rate doubles from 15% to 30%, shrinking but not eliminating the net benefit.

Example — income $265,000, $10,000 deduction, no prior concessional contributions

Div 293 threshold $250,000
Contributions tax (15%) + Div 293 (15%) — effective 30% $3,000
Income tax saved (47% combined rate) $4,700
Net benefit $1,700

At a 47% combined rate (45% + 2% Medicare) with 30% effective contributions tax, the net benefit per dollar is 17% — the same percentage as a 32% earner with no Division 293. The Division 293 charge is billed separately by the ATO after your fund pays contributions tax; it does not change the deduction figure on your tax return.

Worked examples

Example 1 — Alex, self-employed, income $54,000, $2,000 personal contribution

Alex's income is in the co-contribution taper band ($49,293–$64,293). Claiming the deduction saves income tax but forfeits the government co-contribution. The split strategy captures both.

Full deduction

Deductible $2,000
Non-deductible $0
Income tax saved $640
Fund tax $300
Govt co-contribution $0
Total net benefit $340

All non-deductible

Deductible $0
Non-deductible $2,000
Income tax saved $0
Fund tax $0
Govt co-contribution $343
Total net benefit $343

Split: $1,000 non-deductible, rest deductible

Deductible $1,000
Non-deductible $1,000
Income tax saved $320
Fund tax $150
Govt co-contribution $343
Total net benefit $513

Because the co-contribution taper reduces the match to the same amount whether Alex contributes $1,000 or $2,000 non-deductible, leaving $1,000 non-deductible secures the full available match while the remaining $1,000 still earns the deduction benefit.

Example 2 — Sam, salary employee, income $115,000, employer SG $7,000, $15,000 personal contribution

Sam's income is above the co-contribution upper threshold ($64,293), so the co-contribution is unavailable regardless. The full deduction uses $15,000 of the $32,500 cap (after $7,000 employer SG), leaves $10,500 cap remaining, and no Division 293 applies.

Effective deductible (cap remaining after $7,000 SG) $15,000
Income tax saved (32% combined rate) $4,800
Fund tax (15%) $2,250
Division 293 $0
Govt co-contribution (income above threshold) $0
Net benefit — full deduction $2,550
Net benefit — all non-deductible $0
FAQ
What is a Notice of Intent (NOI) to claim a personal super deduction?
If you made a personal (after-tax) contribution to super and want to claim it as a tax deduction, you must lodge a Notice of Intent to Claim a Deduction form (NAT 71121) with your super fund. Your fund acknowledges the notice in writing, and only then can you claim the amount at question D12 of your tax return. The contribution becomes concessional and counts towards your $32,500 concessional cap for 2026-27.
When is the NOI deadline for a 2026-27 contribution?
Section 290-170 ITAA 1997 requires you to give the NOI to your fund on or before whichever is earlier: (a) the day you lodge your 2026-27 tax return, or (b) 30 June 2028. You must also receive the fund's written acknowledgement before claiming the deduction. Lodge early, before starting a pension, withdrawing, or rolling funds out.
Why does claiming the deduction disqualify me from the government co-contribution?
The super co-contribution (up to $500 for 2026-27) only matches non-concessional personal contributions. Once you claim a deduction, the contribution becomes concessional and is excluded from the match. If your income is below $64,293 and you meet the other co-contribution rules, consider leaving up to $1,000 as non-deductible so you can still receive the full $500 match.
What happens if I claim more than my concessional cap allows?
Excess concessional contributions are added to your assessable income and taxed at your marginal rate. You get a 15% tax offset for the contributions tax the fund already paid, plus the ATO charges an excess concessional contributions (ECC) interest charge. You can elect to release up to 85% of the excess from super to pay the tax. The fix is usually to reduce the amount on your NOI to stay at or below the cap — you can lodge a variation before 30 June of the next FY.
Does the deduction count towards my $32,500 concessional cap?
Yes. The amount you claim counts towards your concessional cap, along with employer SG and salary sacrifice. If all three combined exceed $32,500, the excess treatment above applies. The carry-forward rule (unused cap from the last 5 FYs, TSB < $500k at 30 June 2026) can give you extra headroom — use our super carry-forward calculator to check.
I'm 70 — can I still claim a deduction?
Yes, provided you meet the work test: 40 hours of gainful employment in 30 consecutive days during the 2026-27 financial year. A once-only work-test exemption may apply in the year after full retirement if your TSB at the prior 30 June was below $300,000. From age 75 you can only claim for contributions made within 28 days after the end of the month in which you turned 75.
Can a self-employed person claim a personal super deduction?
Yes — self-employed contributions are the most common use of this deduction. The mechanics are identical: make the after-tax contribution, lodge the NOI, receive acknowledgement, claim at D12. The $32,500 concessional cap still applies, and the carry-forward rule can let you deduct up to the full sum of unused caps from 2021-22 through 2025-26 if your TSB was under $500,000 at 30 June 2026.
What breaks an NOI?
Rolling over to another fund, starting a pension with the contribution, or withdrawing the contribution — all BEFORE the fund acknowledges your NOI — invalidates the deduction for that portion (s 290-170(2)). Lodge the NOI first, get written acknowledgement, then move the money if needed.
How is the net tax benefit of a personal super deduction calculated?
Net benefit = (marginal income tax rate + Medicare levy − 15% contributions tax) × deductible amount. For example, at 30% marginal rate with 2% Medicare: (32% − 15%) × $10,000 = $1,700. At 45% marginal rate: (47% − 15%) × $10,000 = $3,200. Division 293 raises the effective contributions tax to 30% for high-income earners, reducing but not eliminating the benefit. The net benefit reference table on this page shows engine-computed values for each 2026-27 bracket.
Does Division 293 make a personal super deduction worthless for high earners?
No. Division 293 raises the effective contributions tax from 15% to 30% when your Division 293 income (taxable income after deduction + total concessional contributions) exceeds $250,000. At a 47% combined marginal rate (45% + 2% Medicare), the net benefit per dollar is 47% − 30% = 17% — the same percentage as a 32% earner with no Division 293. On a $10,000 deduction that is roughly $1,700 net benefit even after Division 293. The charge is billed separately by the ATO and does not reduce the deduction itself.
