Find the right New Zealand secondary tax code and what it costs.
Use for: 'what tax code for my second job', 'is secondary tax a rip off',
'why am I taxed so much on my second job', 'what is SH SL', 'do I get that
money back', filling in an IR330.
CORRECT THE MISCONCEPTION. A secondary code is not a penalty. It
approximates the marginal rate the second income attracts on top of the
first, so roughly the right amount comes out through the year, and any
excess comes back in the year-end square-up. year_end_position says which
way it falls for this person, and a refund is common and normal.
The rates look brutal because they are not income tax rates: each carries
the 1.75% ACC earner levy, and the SL codes add 12% student loan on top. So
31.75% is 30 plus 1.75, not a 31.75% tax rate. The response breaks the rate
into its components; use them when explaining.
ALWAYS ask for the main job income. The code depends on the two incomes
combined, so an answer without it is a guess.
Args:
main_income: Gross annual income from the main job.
secondary_amount: The second income, in the frequency given.
secondary_frequency: annual, monthly, fortnightly or weekly.
has_student_loan: Changes the code to its SL variant.
Returns:
The IR330 code, the flat rate broken into its parts, what is deducted
and what is left, and the estimated year-end bill or refund from these
two sources.
