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_threshold`s 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.
