set_offset: Set offsets

Description

Create parameters for tax offsets.

Usage

set_offset(
  offset_1st = integer(1),
  thresholds = integer(),
  tapers = double(),
  refundable = logical(1)
)
set_offsets(
  ...,
  yr = NULL,
  lito_max_offset = NULL,
  lito_taper = NULL,
  lito_min_bracket = NULL,
  lito_multi = NULL
)
the_MAX_N_OFFSETN()

Value

set_offset

A list of four elements, offset_1st, thresholds, tapers, refundable.

set_offsets

A list of lists created by set_offset.

the_MAX_N_OFFSETN

The maximum number of offsets that may be used.

Arguments

offset_1st

integer(1) The offset available for zero income.

thresholds

integer(N) An sorted integer vector, the thresholds above which each taper applies.

tapers

double(N) The tapers above each threshold. Positive tapers mean that the offset reduces for every dollar above the corresponding threshold.

refundable

bool(1) If FALSE, the default, offsets are non-refundable, meaning that the offset cannot reduce the tax below zero.

...

A set of offsets created by set_offset. May not exceed the_MAX_N_OFFSETN().

yr

NULL / integer(1) If NULL, only the offsets created by ... are used. Otherwise, inherits offsets (such as LITO and LMITO) from the corresponding year.

lito_max_offset, lito_taper, lito_min_bracket, lito_multi

deprecated arguments to adjust (single-threshold) LITO.
