FIF income calculator
Enter your investment values below to calculate your estimated FIF taxable income under both the FDR (Fair Dividend Rate) and CV (Comparative Value) methods. You can use whichever gives you the lower taxable income.
Portfolio opening value
Used by both calculation methods.
The total market value of all your foreign investments at the start of the tax year (1 April). Use your platform's balance on that date, converted to NZD.
FDR method
Fair Dividend RateFDR income = opening value × 5%. Simple, and usually the best method in a rising market.
Did you buy and sell the same holding within this tax year?
If you bought shares in a company and then sold them again within the same tax year (a 'quick sale'), a small adjustment is added to your FDR income.
CV method
Comparative ValueCV income = (closing value − opening value) + dividends. Can be lower than FDR in a flat or falling market. Floors at zero.
The total market value of your foreign investments at the end of the tax year (31 March), in NZD.
Total dividends (after any foreign withholding tax deducted) received from your overseas investments during the tax year, in NZD.
How do I choose a method?
FDR assumes you earned 5% on your opening portfolio value. It's simple and predictable. In a good year (when your portfolio grew more than 5%), FDR usually gives you a lower taxable income.
CV tracks the actual change in your portfolio's value plus dividends received. In a flat or down year, CV income is often lower, or even zero (it can't go below zero).
You can switch methods year-to-year, but you must use the same method for all holdings within a tax year.
