Financial years probably shouldn't be changed
Once you've established your financial year, you are legally limited in your ability to make changes to it. If your financial year begins, for example, on 1st February, you may not be able to move it to 1st March. Consult your accountant or an MYOB Certified Consultant before considering any such change. To locate an MYOB Certified Consultant in your area, see "MYOB Accounting Products and Services" in your Getting Started manual, or visit the MYOB website.
Accounting uses standards used by most accountants. This means that financial years take the name of the calendar year in which they end. For example, if your financial year is from 1st October, 2005, to 30th September, 2006, that year is referred to as "financial year 2006".
