Arguments

.sample.file

A data.table whose variables include those in taxstats::sample_file_1314.

fy.year

The financial year tax scales.

new_cap

The proposed cap on concessional contributions for all taxpayers if age_based_cap is FALSE, or for those below the age threshold otherwise.

new_cap2

The proposed cap on concessional contributions for those above the age threshold. No effect if age_based_cap is FALSE.

new_age_based_cap

Is the proposed cap on concessional contributions age-based?

new_cap2_age

The age above which new_cap2 applies.

new_ecc

(logical) Should an excess concessional contributions charge be calculated? (Not implemented.)

new_div293_threshold

The proposed Division 293 threshold.

use_other_contr

Should MCS_Othr_Contr be used to calculate Division 293 liabilities?

scale_contr_match_ato

(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: $$\frac{\textrm{Total assessable contributions in SMSF and funds}}{\textrm{Total contributions in 2013-14 sample file}}$$.

.lambda

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 \(1 + \lambda(R - 1)\).

reweight_late_lodgers

(logical) Should WEIGHT be inflated to account for late lodgers?

.mu

Scalar weight for WEIGHT. (\(w' = \mu w\)) No effect if reweight_late_lodgers is FALSE.

impute_zero_concess_contr

Should zero concessional contributions be imputed using salary?

.min.Sw.for.SG

The minimum salary required for super guarantee to be imputed.

.SG_rate

The super guarantee rate for imputation.

prv_cap

The comparator cap on concessional contributions for all taxpayers if age_based_cap is FALSE, or for those below the age threshold otherwise.

prv_cap2

The comparator cap on concessional contributions for those above the age threshold. No effect if age_based_cap is FALSE.

prv_age_based_cap

Is the comparator cap on concessional contributions age-based?

prv_cap2_age

The age above which new_cap2 applies.

prv_ecc

(logical) Should an excess concessional contributions charge be calculated? (Not implemented.)

prv_div293_threshold

The comparator Division 293 threshold.

...

Passed to model_new_caps_and_div293.

adverse_only

Count only individuals who are adversely affected by the change.

Value

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.
