The company tax rate change affects imputation in a range of ways. Even if the tax payments that generate imputation credits are made at the previous rate of 30%, those credits might not be distributed until after the new rate has started to apply. This means a set of transitional rules are needed, to cover the changeover to the new rate.
The area of imputation affected most is the maximum imputation ratio, which the new rate sets at 28:72. We have allowed a rate changeover window, during which you can allocate credits that relate to tax paid at 30% at the previous maximum ratio. This prevents any potential disadvantage to your shareholders.

For companies that pay FDP and have a non-standard balance date, be aware that the new rate applies from the start of your 2011-12 income year. If your balance date falls part-way through a quarterly payment period, then you will need to calculate your FDP based on which income year the dividends were received.
For example, your balance date is 31 August, and you received some dividends during July or August 2010, and some during September 2010. When calculating your 30 September quarterly payment, use the previous 30% rate for those received before your balance date (July/August), and the new 28% rate for those received after it (September).
The affected returns and forms will be updated at the relevant time, for you to submit the correct information. Read the Tax Information Bulletin Vol 22, No 7 (August 2010) to get the full details.
