This spreadsheet provides general information only. It is not personal financial, tax, investment, or legal advice. The calculations use publicly available 2025-26 ATO rates and formulas and may not account for every individual circumstance — including HELP/HECS-HELP repayments, Medicare Levy Surcharge, foreign income, trust distributions, or specific state concessions.

We recommend consulting a registered tax agent or qualified financial adviser for advice specific to your situation. We are not affiliated with the Australian Taxation Office (ATO) or any state or territory revenue office.

Welcome

Welcome to your property investment spreadsheet. This tool calculates your after-tax holding cost, negative gearing benefit, depreciation, land tax, and CGT using current ATO rates. Use it to understand your own numbers, on your own schedule.

This guide walks you through everything: making your copy, entering your first property, reading the results, and getting the most out of the spreadsheet. It takes about 10 minutes.

Step 1: Make your copy

You should have received a Property Tax Tools email with your secure access link shortly after purchase. Payhip may also send a receipt, but the spreadsheet access button is in the Property Tax Tools email.

  1. Open the secure delivery link in your browser (Chrome, Firefox, Safari, or Edge all work)
  2. On the delivery page, click Open Google Sheets copy link
  3. The spreadsheet opens in read-only mode — this is the current validated template
  4. Go to File > Make a copy
  5. Choose where to save it in your Google Drive (the default is fine)
  6. Click Make a copy

You now have your own editable version. The original template stays unchanged, so you can always make a fresh copy if needed.

Tip: Bookmark both your own copy and the fresh access link email so you can return to the latest validated template later.

Step 2: Understand the layout

The spreadsheet has several tabs along the bottom. Here’s what each one does:

TabPurpose
Getting StartedBuilt-in checklist and quick orientation for your tier
DashboardSummary view of all your properties and key metrics
Your DetailsEnter investor details and property inputs. Property 1 uses column C; extra properties use D-G.
Tax SummaryCurrent-year tax outcome, negative gearing benefit, and after-tax position
Cash FlowYear-by-year cash flow projection for your tier
Land TaxState-based land tax calculations and projections
DepreciationDivision 40 and 43 inputs and deductions
Capital Gains TaxHold vs sell and CGT estimates
Reference RatesSource-backed tax rates (ATO — Tax rates for Australian residents), land tax thresholds, and levy references (ATO — What is the Medicare levy)
Compare PropertiesPro and Complete only — side-by-side comparison across properties
Rent vs BuyPro and Complete only — compare owning with renting
Rate ScenariosComplete only — test custom rate assumptions and sensitivity

Cell colour guide

  • Blue cells = inputs (edit these)
  • Grey cells = calculated (don’t type in these — they contain formulas)
  • Green cells = key results (your bottom-line numbers)

If you accidentally overwrite a formula, use Ctrl+Z (or Cmd+Z on Mac) to undo. If you badly break your copy, request a fresh access link and make a new clean copy from the validated template.

Step 3: Enter your first property

Go to the Your Details tab and work down column C for your first property. In the Pro and Complete tiers, extra properties use columns D-G.

Investor details

  • Annual taxable income (excluding rental income): Your salary or other income. This helps determine your marginal tax rate and the size of any negative gearing benefit.
  • Tax profile fields: Complete the investor details section before reviewing the tax outputs so the summary tabs use the right assumptions.

Property details

  • Purchase price: What you paid (or expect to pay) for the property.
  • Current market value: Your estimate of what the property is worth now. Used for CGT projections.
  • Land value: The unimproved land value (found on your council rates notice or state valuation). Used for land tax calculations.
  • Property state: The state where the property is located (land tax rates vary by state).
  • Year built: Used for depreciation calculations (Division 43 capital works).

Loan details

  • Loan amount: Your mortgage balance.
  • Interest rate: Your current rate (e.g. 6.25%).
  • Loan type: Interest-only or principal and interest.

Rental income

  • Weekly rent: What the property currently earns (or what you expect it to earn).
  • Vacancy rate: A percentage to account for periods without tenants. 2–4% is typical for metro areas.

Expenses

Fill in your annual expenses. Common ones include:

  • Council rates
  • Water rates
  • Strata/body corporate fees
  • Property management fees (typically 7–10% of rent)
  • Insurance (landlord + building)
  • Maintenance and repairs
  • Land tax (auto-calculated from the land value and state you entered)

Leave any expense at $0 if it doesn’t apply to your property.

Depreciation (Pro and Complete tiers)

Step 4: Read your results

Once you’ve entered your details, the key result tabs update automatically:

Key numbers to look at

  • Dashboard: Your high-level summary across properties, including portfolio totals.
  • Tax Summary: Net rental income, negative gearing benefit, and after-tax position.
  • Cash Flow: Forward-year projections based on your tier’s horizon.
  • Land Tax: State-specific land tax estimate based on the land value and state you entered.
  • Capital Gains Tax: Hold vs sell and estimated after-tax sale outcomes.

Pro and Complete tier results

  • Compare Properties: See how multiple properties stack up side by side.
  • Rent vs Buy: Compare ownership cash flow against renting.
  • Rate Scenarios (Complete): Test how different interest-rate assumptions change the result.

Step 5: Run scenarios

The real power of the spreadsheet is in comparing scenarios. Try changing:

  • Interest rate: What happens if rates go up by 0.5% or 1%? How does your weekly cost change?
  • Weekly rent: What if rent increases by $20/week? How does that affect your yield and cash flow?
  • Purchase price: Comparing two properties? Enter them in separate property columns and compare on the Dashboard or Compare Properties tab.
  • Holding period: Use the hold vs sell analysis to see how long you need to hold before selling makes sense.
  • Rate assumptions: In the Complete tier, use the Rate Scenarios tab to test custom inputs without rewriting the base reference sheet.

Tip: Before changing inputs for a scenario, note down your current results so you can compare.

Step 6: Use it with your accountant

The spreadsheet is not a replacement for professional tax advice — but it makes your accountant meetings much more productive.

Before your appointment:

  1. Print or share the property summary from the Dashboard tab
  2. Note any questions that came up while entering your numbers (e.g. “Should I get a depreciation schedule?”)
  3. Check your expenses are complete — your accountant can spot missing deductions

Your accountant can verify the numbers and advise on items specific to your situation that a calculator can’t handle (e.g. private rulings, CGT main residence exemptions, trust structures).

Tips for getting the most out of the spreadsheet

  1. Update it regularly. Enter actual expenses and rent when you receive them (not just estimates). This gives you an accurate running total for tax time.
  2. Compare properties before buying. Enter prospective properties in separate property columns and compare them side by side on the Dashboard or Compare Properties tab.
  3. Check the Reference Rates tab at the start of each financial year. If tax rules change or you want the latest validated template, go back to your secure access link and make a fresh copy.
  4. Use realistic vacancy rates. 0% vacancy is unrealistic. Even in strong markets, allow 2–4% for turnover between tenants.
  5. Include all expenses. Many investors underestimate costs. Don’t forget: pest control, smoke alarm compliance, landlord insurance excess, end-of-lease cleaning, and advertising costs between tenants.

Frequently asked questions

How do I make a copy of the spreadsheet?
Open the Google Sheets link you received after purchase. Go to File > Make a copy. This creates your own editable version in your Google Drive. The original template is read-only — your copy is yours to edit freely.
Can I share the spreadsheet with my partner or accountant?
Yes. In Google Sheets, click Share and add their email address. You can give them view-only access (recommended for accountants) or full edit access (useful for a partner who co-owns the property).
What do the cell colours mean?
Blue cells are inputs — these are the cells you edit. Grey cells are calculated — they contain formulas and update automatically. Green cells are key results. Do not type into grey or green cells, as this will overwrite the formulas.
How do I add a second property (Pro and Complete tiers)?
Each property has its own tab at the bottom of the spreadsheet. The Pro tier includes 3 property tabs; the Complete tier includes 5. Click on the 'Property 2' tab and enter your details there. The Summary tab pulls all properties together automatically.
Can I change the interest rate to see what happens?
Yes. Change the interest rate in the loan details section of any property tab. All downstream calculations — including monthly repayments, net rental income, negative gearing benefit, and cash flow projections — will update automatically.
