A successful CSC claim can change your income for decades, but it also interacts with tax, DVA payments and insurance. CSC itself recommends getting financial advice before a retrospective application. Here's what to understand first.
MilitarySuper invalidity pensions are CPI-indexed and not reduced by other income. ADF Cover and DFRDB use different formulas – see Class A, B and C explained.
In Commissioner of Taxation v Douglas (2020), the Full Federal Court held that DFRDB and MSBS invalidity pensions starting on or after 20 September 2007 are taxed as super lump sums, generally meaning less tax. Parliament preserved this outcome for those schemes and introduced a veterans' invalidity pension tax offset. It does not cover ADF Cover. A backdated pension may mean amending earlier tax returns.
If you're approved retrospectively and received DVA incapacity payments for the same period, DVA commonly recovers the overpayment from your CSC arrears – and may seek any shortfall from you. For some veterans the net gain may be modest. Get the numbers modelled before lodging.
If you had lifePLUS Protect auto cover after separation, retrospective approval as Class A or B can cancel that cover, with premiums refunded to your ADF Super account.
New claims are assessed under the MRCA, DRCA incapacity recipients moved to the MRCA, VEA-only veterans can claim MRCA incapacity payments, and some offsetting rules changed. These can alter how a CSC pension nets out.
