Arguments

yr

integer(1) A year.

ordinary_tax_thresholds

A numeric vector specifying the lower bounds of the brackets for "ordinary tax" as defined by the Regulations. The first element should be zero if there is a tax-free threshold.

ordinary_tax_rates

The marginal rates of ordinary tax. The first element should be zero if there is a tax-free threshold. Since the temporary budget repair levy was imposed on a discrete tax bracket when it applied, it is not included in this function.

medicare_levy_taper

The taper that applies between the _lower and _upper thresholds.

medicare_levy_rate

The ordinary rate of the Medicare levy for taxable incomes above medicare_levy_upper_threshold.

medicare_levy_lower_threshold

Minimum taxable income at which the Medicare levy will be applied.

medicare_levy_lower_sapto_threshold, medicare_levy_upper_sapto_threshold

The equivalent values for SAPTO-eligible individuals (not families).

medicare_levy_lower_family_threshold, medicare_levy_upper_family_threshold

The equivalent values for families.

medicare_levy_lower_family_sapto_threshold, medicare_levy_upper_family_sapto_threshold

The equivalent values for SAPTO-eligible individuals in a family.

medicare_levy_lower_up_for_each_child

The amount to add to the _family_thresholds for each dependant child.

medicare_levy_upper_threshold

Minimum taxable income at which the Medicare levy will be applied at the full Medicare levy rate (2% in 2015-16). Between this threshold and the medicare_levy_lower_threshold, a tapered rate applies, starting from zero and climbing to medicare_levy_rate.

Offsets

List of offsets created by set_offsets.

sapto_max_offset

The maximum offset available through SAPTO.

sapto_lower_threshold

The threshold at which SAPTO begins to reduce (from sapto_max_offset).

sapto_taper

The taper rate beyond sapto_lower_threshold.

sapto_max_offset_married, sapto_lower_threshold_married, sapto_taper_married, sapto_lower_threshold_illness, sapto_max_offset_illness

As above, but applied to members of a couple.

sapto_pension_age

The age at and above which the SAPTO is to apply.

fix

integer(1) If 0L, the default, an error will be emitted if parameters are inconsistent; if 1L, inconsistencies will be fixed.
