DZ 16: Geothermal wells between 31 March 2003 and 17 May 2006
or “Rules for claiming expenses on geothermal wells completed or purchased between 31 March 2003 and 17 May 2006”

You could also call this:

“Tax deduction for pre-1996 aquaculture business improvements”

If you spent money to improve your aquaculture business before the 1995-96 income year, you might be able to claim some of that money back on your taxes. This applies if you would have been allowed to claim the money under section DO 12 if you had spent it in the 1995-96 income year or later.

To figure out how much you can claim, you need to use a special calculation. You multiply 125% by a percentage from schedule 20, parts B to F, and then multiply that by the reduced value of your improvement.

The percentage you use depends on what kind of improvement you made. You can find this in the schedule mentioned above.

The ‘reduced value’ means the current value of your improvement, which is probably less than what you originally paid for it.

Remember, even though this rule lets you claim for improvements made before 1995-96, you still need to follow the general rules about what you can claim on your taxes.
