Many people often wonder why their accountant asks for their spouse income. 

The answer is simple, the ATO requires you to make a legal declaration whether you had a spouse during the year. If you do have a spouse, you must include various details of your spouse, such as their taxable income.

We understand that some people do not want to share this information, however in order to be compliant you must include this on your tax return as it can influence different aspects of your tax return such as the medicare levy surcharge and private health insurance rebate.
