Tax - Income distributions of individual customers 2019
Taxable income for individuals: income on which personal income tax is assessed for the March year. For people with IR3 tax returns or Personal tax summaries, this is income from all taxable sources less allowable deductions and losses. People with negative income because of losses are recorded as having nil taxable income in the tables.
Up until 2018, for people who are non-filers, taxable income was assumed to be (limited to) their total PAYE gross earnings in the year ended 31 March.
This calculation did not include interest, dividends, KiwiSaver, or other PIE earnings. From 2019, these income streams are included (although for PIEs it is only if the PIE income was taxed at the wrong rate).
From 2019, the inclusion of additional people with passive-only income such as interest, dividend, and PIE income will have changed the overall distribution by introducing more low income earners, particularly children. Moreover, other people will now have bigger incomes through the inclusion of additional income streams from their investments. This is particularly true of people who did not previously file a tax return or receive a personal tax summary.
Limitations of the data
The data is based on a random sample and has been scaled up to population estimates. The sample is 2% of wage and salary earners, and 10% of IR3 filers.
The following people are included in the dataset:
- anyone who filed an IR3 personal tax return for that income year, even if they filed a nil return or a loss
- anyone who paid PAYE via an employer, including recipients of taxable welfare benefits, New Zealand Superannuation, earnings-related accident compensation income, student allowances, and paid parental leave, even if they did not file a return.
- anyone who received an automatic income tax assessment at year end. From 2019, these are created for anybody with income during the year from any source for which Inland Revenue holds information; for example wages and salaries, taxable welfare benefits and transfers, interest, dividends, and income earned through portfolio investment entities (PIEs) if it was taxed at the wrong rate.
- People whose only income was from interest, dividends, or PIEs, all fully taxed at source so they did not, prior to 2019, need to file a tax return (included by way of automatic assessment)
- Children (included if they filed or had automatic assessment income)
- People with part year income (included if they filed or had automatic assessment income)
The following people are not included:
- people with no taxable income and who did not file a tax return
Changes to data collection/processing
There has been a structural break in the coverage of this data from the 2018/19 income year. The effect has been to increase the number of people covered by the data, particularly those who earn only passive income.
