KNOW YOUR NUMBERS
Useful to know.
Before you calculate.
Which income amount should I enter?
Monthly employment amounts include taxable cash and non-cash benefits before APIT. Annual tax defaults to income that is already taxable; personal relief is only deducted if you choose the assessable-income option. EPF, other payroll deductions and tax credits are not included.
Can I calculate an earlier period?
Yes. Choose a dated archived period. Bonus and non-resident lump-sum rules for April–December 2022 use the separate nine-month table. January–March 2023 transitional annual calculations are not covered; the 2023 bonus tool applies from April 2023.
What is included in these estimates?
Each calculator explains its income basis and applicable conditions. Export and foreign-employment tools apply only to qualifying income, and exclude mixed local income. The 2018/19 terminal-benefit tool excludes ETF retention pending an IRD direction. Do not use a historic table for a current payment.
