Income tax calculator

Use this simple, accurate tax calculator to work out how much you will be paid.

This calculator now includes tax rates for the proposed 2019-2020 tax year as well as the legislated changes in 2022 and 2024. The most significant change is the extension of a new low and middle income tax offset. This offset will be given as a tax return at the end of the year so it won't effect your pay. This new offset is in addition to the existing low income offset.

How many weeks in a year?

This calculator adopts the approximation of 52 weeks per year to convert annual to weekly pay. However, there aren't exactly 52 weeks in a year and if you are being paid weekly or fortnightly there will be some years where there may be 53 or 27 pay days in a year. The actual year depends on which day of the week you are paid.

The Gregorian calendar is defined as having exactly 20871 weeks in a 400 year cycle, therefore an average year is exactly 52.1775 weeks long and months average 4.348125 weeks. This is defined in the ISO week-numbering year. These "leap-weeks" occur every 5-6 years and "leap-fortnights" occur approximately every 11 years. The ATO's tax tables, and most accounting software use a standard 52 weeks per year calculations. In some years a weekly or fortnightly salary earner may need to pay additional income tax for the additional pay they received. The onus is on the employee to make this request, otherwise the 52 weeks per year calculation is made. Because of this anomaly, most employers who define pay on an annual basis adopt the monthly pay cycle.
