A data.table
whose variables include those in taxstats::sample_file_1314
.
The financial year tax scales.
The proposed cap on concessional contributions for all taxpayers if age_based_cap
is FALSE, or for those below the age threshold otherwise.
The proposed cap on concessional contributions for those above the age threshold. No effect if age_based_cap
is FALSE.
Is the proposed cap on concessional contributions age-based?
The age above which new_cap2
applies.
(logical) Should an excess concessional contributions charge be calculated? (Not implemented.)
The proposed Division 293 threshold.
Should MCS_Othr_Contr
be used to calculate Division 293 liabilities?
(logical) Should concessional contributions be inflated to match aggregates in 2013-14? That is, should the concessional contributions by multiplied by the internal constant grattan:::super_contribution_inflator_1314
, which was defined to be: $$\frac{\textrm{Total assessable contributions in SMSF and funds}}{\textrm{Total contributions in 2013-14 sample file}}$$.
Scalar weight applied to concessional contributions
. \(\lambda = 0\) means no (extra) weight. \(\lambda = 1\) means contributions are inflated by the ratio of aggregates to the sample file's total. For \(R = \textrm{actual} / \textrm{apparent}\) then the contributions are scaled by \(1 + \lambda(R - 1)\).
(logical) Should WEIGHT be inflated to account for late lodgers?
Scalar weight for WEIGHT. (\(w' = \mu w\)) No effect if reweight_late_lodgers
is FALSE
.
Should zero concessional contributions be imputed using salary?
The minimum salary required for super guarantee to be imputed.
The super guarantee rate for imputation.
The comparator cap on concessional contributions for all taxpayers if age_based_cap
is FALSE, or for those below the age threshold otherwise.
The comparator cap on concessional contributions for those above the age threshold. No effect if age_based_cap
is FALSE.
Is the comparator cap on concessional contributions age-based?
The age above which new_cap2
applies.
(logical) Should an excess concessional contributions charge be calculated? (Not implemented.)
The comparator Division 293 threshold.

Count only individuals who are adversely affected by the change.
For model_new_caps_and_div293
, A data.frame, comprising .sample.file
, the superannuation variables generated by apply_super_caps_and_div293
, and two variables prv_revenue
and new_revenue
which give the tax (income tax, super tax, and division 293 tax) payable by that taxpayer in the comparator scenario and the proposed scenario, respectively.
For n_affected_from_new_cap_and_div293
, the number of individuals affected by the proposed changes.
For revenue_from_new_cap_and_div293
, the extra revenue expected from the proposed changes.
