How the numbers work: tax on investments and property
99 worked calculations taken from the guides on this subject, each shown a line at a time with the figure it arrives at.
A calculator gives you an answer. These show the arithmetic behind one, which is what you need when you have to check it, explain it to somebody else, or follow it with your own numbers. Every heading links to the guide that works it through in full, and that guide is where any rate or threshold is kept current.

When Do FIF Rules Apply?
- Example:
- US shares (cost): $30,000
- UK shares (cost): $15,000
- Total: $45,000
Below $50,000 → FIF rules don't apply
Method 1: Fair Dividend Rate (FDR) - Most Common
- FIF Income = Opening Market Value × 5%
- Plus: Actual dividends received (taxed separately)
- Note: Capital gains/losses are ignored
Method 1: Fair Dividend Rate (FDR) - Most Common
- Opening value (1 April): $100,000
- Closing value (31 March): $115,000
- Dividends received: $2,000
- Actual return: $15,000 + $2,000 = $17,000 (17%)
- FDR Calculation:
- FIF income: $100,000 × 5% = $5,000
- Dividend income: $2,000
Total taxable: $7,000 (not the actual $17,000)
Method 2: Comparative Value (CV)
- CV Income = (Closing Value - Opening Value) + Distributions - Contributions
Method 2: Comparative Value (CV)
- Opening value: $100,000
- Closing value: $95,000
- Dividends: $2,000
- Additional purchases: $0
- CV Calculation:
- ($95,000 - $100,000) + $2,000 - $0
- Tax payable: $0 (loss carried forward)
= -$3,000 (loss)
Method 4: Cost Method (CM)
- FIF Income = Actual distributions received
- Capital gains/losses = Ignored
FDR Method: Step-by-Step
- FIF Income = Opening Market Value × 5%
FDR Method: Step-by-Step
- Total FIF Income = (Opening Value × 5%) + Dividends
- Tax Payable = Total FIF Income × Your Tax Rate
FDR Method: Step-by-Step
- Investment in US S&P 500 ETF:
- Opening value (1 April): US$80,000
- Exchange rate: NZ$1.65 per US$
- Opening value NZD: US$80,000 × 1.65 = NZ$132,000
- FDR Income:
- NZ$132,000 × 5% = NZ$6,600
- Dividends:
- Received during year: US$2,000 = NZ$3,300
- US withholding tax (15%): NZ$495
- Total Taxable Income:
- FIF income: NZ$6,600
- Dividend income: NZ$3,300
- Tax Calculation (33% rate):
- NZ$9,900 × 33% = NZ$3,267
- Less foreign tax credit: -NZ$495
Total: NZ$9,900
CV Method: Step-by-Step
- CV Income = Closing Value - Opening Value + Distributions - Contributions
CV Method: Step-by-Step
- European Shares (Market Crash Year):
- Opening value (1 April): NZ$100,000
- Closing value (31 March): NZ$75,000
- Dividends received: NZ$1,500
- Additional purchases: NZ$0
- CV Calculation:
- (NZ$75,000 - NZ$100,000) + NZ$1,500 - NZ$0
- = -NZ$25,000 + NZ$1,500
- Tax Impact:
- Tax payable: $0
- Loss carried forward: NZ$23,500
- Can offset against future FIF income from same investment
= -NZ$23,500 (loss)
CV Method: Step-by-Step
- UK Investment Trust (Growth Year):
- Opening value: NZ$80,000
- Closing value: NZ$92,000
- Dividends: NZ$2,400
- Additional purchase (July): NZ$10,000
- CV Calculation:
- (NZ$92,000 - NZ$80,000) + NZ$2,400 - NZ$10,000
- = NZ$12,000 + NZ$2,400 - NZ$10,000
- Tax (33% rate):
= NZ$4,400 FIF income
Exchange Rate Considerations
- Investment value: US$50,000 (unchanged)
- 1 April rate: NZ$1.60 per US$ → NZ$80,000
- 31 March rate: NZ$1.70 per US$ → NZ$85,000
- CV Method:
- NZ$85,000 - NZ$80,000 = NZ$5,000 FIF income
- Even though US$ value didn't change!
🔢 Real-World Examples
- Investment: Vanguard S&P 500 ETF (US-listed)

- Tax (33% rate):
- NZ$9,200 × 33% = NZ$3,036
- Less US tax credit: -NZ$480
NZ$6,000 + NZ$3,200 = NZ$9,200
🔢 Real-World Examples
- If CV method was used instead:
- CV income: NZ$15,000 + NZ$3,200 = NZ$18,200
- Tax at 33%: NZ$6,006
- Less US credit: -NZ$480
- CV tax: NZ$5,526
FDR saved Jane: NZ$5,526 - NZ$2,556 = NZ$2,970
- Investment: European stock portfolio
- Opening value: NZ$80,000
- Closing value: NZ$70,000
- Actual loss: NZ$10,000 (-12.5%)
- Dividends received: NZ$1,500
- CV Calculation:
- (NZ$70,000 - NZ$80,000) + NZ$1,500 - NZ$0
- = -NZ$10,000 + NZ$1,500
- Tax Impact:
- Current year tax: $0
- Loss carried forward: NZ$8,500
= -NZ$8,500 (loss)
- Next year, if portfolio recovers:
- Opening: NZ$70,000
- Closing: NZ$80,000
- Dividends: NZ$1,500
- CV income: NZ$10,000 + NZ$1,500 = NZ$11,500

- FIF income: NZ$100,000 × 5% = NZ$5,000
- Dividend income: NZ$1,000
- Total: NZ$6,000
- Tax (33%): NZ$6,000 × 0.33 = NZ$1,980
After-tax return: NZ$9,000 - NZ$1,980 = NZ$7,020
- CV income: (NZ$108,000 - NZ$100,000) + NZ$1,000
- = NZ$9,000
- Tax (33%): NZ$9,000 × 0.33 = NZ$2,970
After-tax return: NZ$9,000 - NZ$2,970 = NZ$6,030
- NZ$7,020 vs NZ$6,030 after-tax return
FDR is better: Saves NZ$990 in tax

$58,000 > $50,000 threshold ✗ FIF rules now apply
FIF CM Method Guide - Comparative Value Method
CV Method Formula
- FIF Income = (Closing Value - Opening Value) + Distributions
- Where:
- Closing Value = Market value at 31 March (year end)
- Opening Value = Market value at 1 April (year start)
- Distributions = Dividends, distributions received during year
Simple CV Method Example
- Opening value (1 April 2024): NZD $120,000
- Closing value (31 March 2025): NZD $145,000
- Dividends received: NZD $4,500
- Capital gain: $145,000 - $120,000 = $25,000
- FIF income: $25,000 + $4,500
FIF Income = $29,500
Advantages of CV Method
- Opening: $100,000, Closing: $85,000
- Loss: $15,000
- Can offset against other income
Market Value Determination
- Use IRD's published exchange rates for 1 April and 31 March
- Or use actual rates from reputable source (bank)
Example 1: Basic Full-Year Holding
- 1 April 2024: 500 units at USD $420 = USD $210,000
- Exchange rate 1 April: 0.60 (NZD/USD)
- Opening value NZD: $210,000 ÷ 0.60 = $350,000
Example 1: Basic Full-Year Holding
- 31 March 2025: 500 units at USD $465 = USD $232,500
- Exchange rate 31 March: 0.58 (NZD/USD)
- Closing value NZD: $232,500 ÷ 0.58 = $400,862
Example 1: Basic Full-Year Holding
- Dividends received: USD $5,250
- Average rate: 0.59
- Dividends NZD: $5,250 ÷ 0.59 = $8,898
Example 1: Basic Full-Year Holding
- Capital gain: $400,862 - $350,000 = $50,862
- Plus dividends: $8,898
Total FIF Income: $59,760
Example 2: Mid-Year Purchase
- No holdings at 1 April 2024 (opening value: $0)
- Purchased 15 October 2024: USD $75,000
- Exchange rate: 0.62
- Cost NZD: $75,000 ÷ 0.62 = $120,968
Example 2: Mid-Year Purchase
- 31 March 2025 value: USD $82,000
- Exchange rate: 0.58
- Closing value NZD: $82,000 ÷ 0.58 = $141,379
Example 2: Mid-Year Purchase
- Closing value: $141,379
- Cost: $120,968
- FIF income: $141,379 - $120,968
FIF Income: $20,411
Example 3: FIF Loss
- Opening value 1 April: $200,000
- Closing value 31 March: $165,000
- Dividends: $3,000
- Capital loss: $165,000 - $200,000 = -$35,000
- Plus dividends: $3,000
FIF Income: -$32,000 (Loss)
Example 5: CV vs FDR Comparison
- Opening value: $150,000
- Closing value: $168,000
- Dividends: $2,500
Example 5: CV vs FDR Comparison
- FIF income = ($168,000 - $150,000) + $2,500
- Tax at 33%: $6,765
= $20,500
Example 5: CV vs FDR Comparison
- FIF income = $150,000 × 5%
- Tax at 33%: $2,475
= $7,500
Handling Transactions During Year
- Opening: $100,000
- Bought more (Oct): $30,000
- Closing: $145,000
- Gain: $145,000 - ($100,000 + $30,000) = $15,000
Handling Transactions During Year
- Opening: $100,000
- Sold portion (Dec): $25,000 (proceeds)
- Closing: $80,000 (remaining)
- Total value: $80,000 + $25,000 = $105,000
- Gain: $105,000 - $100,000 = $5,000

FIF DRR Method Guide
DRR Method Formula
- FIF Income = Total Distributions Received
- Where:
- Distributions = Dividends, interest, other distributions in NZD
- Capital gains = Ignored
- Capital losses = Ignored
Simple DRR Example
- Investment value: $100,000 (irrelevant for DRR)
- Dividends received: $7,500
FIF Income = $7,500
Example 1: High Dividend Stock
- Investment: UK dividend stock
- Dividends received: GBP £4,200
- Exchange rate (average): 0.50
- Dividends NZD: £4,200 ÷ 0.50 = $8,400
FIF Income = $8,400
Example 2: REIT Investment
- US REIT value: $150,000 (not used in calc)
- Quarterly distributions:
- Q1: $2,100, Q2: $2,250, Q3: $2,200, Q4: $2,150
- Total: $8,700
FIF Income = $8,700
Example 2: REIT Investment
- FDR would tax: $150,000 × 5% = $7,500
- DRR taxes: $8,700
- DRR worse by $1,200 income
- But yield is 5.8%, close to FDR 5% threshold
Example 3: Zero Dividend Growth Stock
- Tesla stock: $80,000 value
- Dividends: $0 (Tesla pays no dividend)
Cannot use DRR (no distributions)
🌍 Real-World DRR Examples
- Total REIT portfolio: $300,000
- Average yield: 6.5%
- Annual distributions: $19,500
- FIF Income (DRR): $19,500
- Tax at 33%: $6,435
🌍 Real-World DRR Examples
- FIF Income: $300,000 × 5% = $15,000
- Tax: $4,950
FDR saves $1,485
🌍 Real-World DRR Examples
- Tech growth portfolio: $250,000
- Yield: 1.2%
- Distributions: $3,000
- DRR income: $3,000
- FDR income: $12,500
DRR better (saves $9,500 taxable income)
FIF Cost Method Guide
Cost Method Formula
- FIF Income = (Closing Value - Cost of Acquisition) + Distributions
- Where:
- Closing Value = Market value at 31 March (year end)
- Cost = Purchase price + transaction costs in NZD
- Distributions = Dividends received after purchase
Simple Example
- Purchase date: 15 October 2024
- Cost: USD $50,000
- Exchange rate: 0.62 NZD/USD
- Cost NZD: $50,000 ÷ 0.62 = $80,645
- 31 March 2025 value: USD $54,500
- Exchange rate: 0.58
- Closing NZD: $54,500 ÷ 0.58 = $93,966
- Dividends NZD: $850
- FIF income = ($93,966 - $80,645) + $850
= $14,171
Example 1: Purchase Early in Year
- Purchased: 10 April 2024 (day after year start)
- Cost: $75,000 NZD
- 31 March 2025: $82,000 NZD
- Dividends: $1,200
- FIF income = ($82,000 - $75,000) + $1,200 = $8,200
Example 2: Purchase Late in Year
- Purchased: 28 February 2025 (1 month before year end)
- Cost: $100,000 NZD
- 31 March 2025: $101,500 NZD
- Dividends: $0 (too soon)
- FIF income = $101,500 - $100,000 = $1,500
Example 3: Multiple Purchases Same Year
- 31 March 2025 value: $85,000
- Dividends: $2,100
- FIF income = ($85,000 - $75,000) + $2,100 = $12,100
🌍 Real-World Examples
- Purchased Vanguard ETF: September 2024
- Cost USD $80,000 = NZD $128,000
- 31 March value: USD $86,000 = NZD $145,000
- Dividends: NZD $2,800
- FIF income = ($145,000 - $128,000) + $2,800 = $19,800
- Tax at 33%: $6,534
🌍 Real-World Examples
- Purchased: November 2024, Cost $90,000
- Market crash by 31 March: $78,000
- Dividends: $1,500
- FIF income = ($78,000 - $90,000) + $1,500 = -$10,500
- Loss reduces other taxable income by $10,500
Bright-Line Test Explained - New Zealand
Why the Rule Exists
- Property speculator buys property
- Holds briefly, makes improvements, sells at significant profit
- Claims no speculative intention - "circumstances changed"
- IRD must prove intention to speculate (nearly impossible)
- Speculator pays no tax despite clear profit-seeking behaviour
The Main Home Exclusion Explained Simply
- Scenario: You buy property, live in it as main home, later convert to rental, then sell within bright-line period
- Period lived in as main home: Protected from bright-line tax
- Period used as rental: May be subject to bright-line tax
- Result: Partial exemption - apportioned based on use periods
Why Keeping Records Matters
- Without main home evidence: IRD may reject your exemption claim
- Result: Tax liability on sale you believed was exempt
- Without improvement cost receipts: Gain calculated ignoring expensive improvements
- Result: Higher taxable gain than reality, substantially more tax owed
- Prevention: Keep everything from purchase to sale completion
Tax on Rental Income
You Are Taxed on the Profit
- Rent received over the year
- Less allowable expenses
- Equals net rental profit (or loss)
- The profit is added to your other income and taxed at your rate
Ring-Fencing of Rental Losses
- Rental makes a $5,000 loss this year
- You cannot deduct it from your salary income
- The loss carries forward
- It offsets rental profit in a future year
A Simple Landlord Checklist
- 1. Record all rent received
- 2. Keep invoices and split repairs from improvements
- 3. Confirm the current interest deductibility rules
