What you are short of is gross taxable income. Getting the pension will help. If you have cash invested with banks then make sure it is term investment (taxable) rather than a term fund which is PIE income and does not get included of tax return. You will need to reassess this when you get the pension.

Another way is to buy some shares you like that have none or very little imputation credits. I use RYM and SUM for this purpose. Then you have more income to declare.
