When a property is sold, everyone seems to know what they are owed: the bank, council, lawyers, agents and IRD. But who checks what may be owed back to the owner? Tracy Lynch follows the ledgers behind mortgages, interest, GST, rates and property sales, arguing that every liability, deduction, credit and adjustment should be reconciled against the underlying records. The principle is simple: if an amount is due, prove it. If a lawful entitlement exists, apply it.
When a property changes hands, almost everybody involved knows precisely what they are entitled to collect. But has the same care been taken to establish everything the property owner is legally entitled to receive, deduct or claim?
Opinion & Analysis by Tracy Lynch
For months, We Review the Crown has been following the documentary trail behind mortgages: mortgage instruments, security agreements, bank ledgers, titles, lawyer certifications, rates accounts, default notices, enforcement costs, mortgagee sales and settlement statements. Following those records has now led to another institution sitting behind many significant property transactions: Inland Revenue. We_Review_the_Crown_IRD_Review_…
The question is deceptively simple. We have been trained to ask, “What do I owe?” Perhaps it is time we also asked, “What does the ledger say I am entitled to?”
This is not an allegation that every homeowner is owed money. It is not a claim that every mortgage is defective, every property sale creates a tax credit, or Inland Revenue is concealing refunds. It is a call for something much more fundamental: a complete reconciliation.
A property transaction can create liabilities. But depending upon the circumstances, it can also involve deductions, credits, adjustments, carried-forward losses, GST treatment and other tax consequences. If enormous care is taken to establish what a property owner must pay, why shouldn't equal care be taken to establish what that same person is lawfully entitled to claim?

Everybody Has a Figure for You
Consider what happens at settlement. The bank produces its discharge figure. The council wants rates cleared or apportioned. The lawyer charges fees. The real estate agent receives commission. There may also be valuation costs, break fees, enforcement costs and other legal expenses.
Everybody seems to have a number.
But who reconstructs the other side of the account?
What was deductible? What had previously been denied? What credits or losses remain? What GST treatment actually applies? What is the final tax position after every relevant record has been reconciled?
Those questions sit at the heart of this first IRD review. We_Review_the_Crown_IRD_Review_…
GST Is Only Part of the Picture
A recent mortgage-enforcement file we examined contained a GST declaration asking the owner to confirm that the proposed property sale would not constitute a taxable supply because the owner was not GST registered and had not claimed GST on the building.
That document matters because somebody had determined that the tax character of the transaction was sufficiently important to require a formal declaration.
So what else was checked?
GST treatment of land is fact-specific. Registration, taxable activity, use of the land, purchaser status and zero-rating rules can all affect the outcome. The point is not that GST necessarily produces money for the property owner. The point is that its treatment should be identified from the facts and supported by the records rather than assumed. We_Review_the_Crown_IRD_Review_…
Follow the Interest
Mortgage interest provides another ledger.
For the homeowner, interest is money leaving the household. For the lender, it is income recorded within a financial system. Its tax treatment for the borrower, however, depends upon what the borrowed money was used for and the tax rules applying during the relevant income year.
Private home-loan interest is not automatically deductible merely because somebody paid it. Income-producing property can produce a different analysis.
Residential-property interest rules have also changed over time. That makes reconstruction on a year-by-year basis important. Where the sale of a property is itself taxable, previously denied interest can, in some circumstances, affect the eventual tax calculation.
That does not mean every homeowner gets their mortgage interest back. It means the records should be examined before anybody assumes what the answer is. We_Review_the_Crown_IRD_Review_…
The question every taxpayer should be entitled to ask is straightforward:
“Before calculating what I owe, did you include everything I am lawfully entitled to claim?” We_Review_the_Crown_IRD_Review_…
Two Ledgers, One Economic Relationship
Our mortgage investigation has already asked who received the interest, how the loan was accounted for, whether fees and recoveries were correctly recorded and who held the legal and economic entitlement to the receivable.
Now turn the telescope around.
From the property owner's side, how much interest was actually paid? What expenditure was incurred? What was claimed? What was denied? What was carried forward? What happened when the property was eventually sold?
These are two ledgers describing the same underlying economic relationship from opposite ends. The numbers should ultimately be capable of reconciliation against primary records. We_Review_the_Crown_IRD_Review_…
What Exactly Did the Mortgage Secure?
A mortgage is security, but that does not remove the need to identify precisely what obligations were secured.
A proper audit should identify the original loan obligation, registered mortgage, incorporated terms, any all-obligations provisions, guarantees, future advances and payments for matters such as rates or insurance that may subsequently have been added to the secured debt.
This becomes particularly important when another institution enters the ledger.
Suppose council rates are paid by a lender and subsequently added to the secured account. The council's ledger and the bank's ledger are now connected. Before that amount is compounded with interest, the originating amount itself should be capable of verification.
Verify the first dollar before compounding the next one. We_Review_the_Crown_IRD_Review_…
Bills, Notes and the Need for Evidence
There is another area where considerable confusion can arise: bills of exchange, promissory notes and other negotiable instruments.
A loan agreement, mortgage, accounting entry and negotiable instrument are not automatically the same thing.
If someone claims that a bill or note existed, produce it.
Who issued it? Who held it? What was the consideration? Was it transferred or endorsed? How was it discharged? How was it treated in the accounts?
And if no such instrument existed, say so and identify the actual documents that created the obligation.
This is important because investigations can become derailed when terminology takes the place of evidence. We should not construct a theory around a label. Produce the instrument, determine its legal character, follow the movement of value and then establish how the transaction was accounted for and taxed. We_Review_the_Crown_IRD_Review_…
Follow the money, but follow the documents with it.
Reconstruct the Entire Property Sale
When a property is sold, the transaction should be capable of being reconstructed as a transparent closing ledger.
Start with the gross sale price. Then identify verified settlement expenses, apportioned and verified rates, the verified mortgage discharge and other authorised deductions. What remains should reconcile to the net proceeds payable to the owner.
Every material deduction should have both a primary document and a corresponding ledger entry. We_Review_the_Crown_IRD_Review_…
Alongside that settlement ledger sits the tax reconciliation.
Depending upon the circumstances, that may require examination of acquisition cost, improvements, use of the property, sale expenses, mortgage interest, other property expenditure, previous tax returns, GST records, carried-forward losses and the land-sale rules applying to the particular transaction. We_Review_the_Crown_IRD_Review_…
The source documents an owner may need are therefore extensive: original loan agreements, registered mortgage terms, complete loan ledgers, annual interest certificates, income-tax returns, property or rental schedules, rates records, settlement statements, GST returns where applicable, enforcement records, valuations and the calculation producing the final net proceeds.

Will This in Fact Make New Zealand Stronger?
Will this in fact make New Zealand stronger? A society in which citizens can obtain the records underlying significant financial demands, verify the calculations made against them and require institutions to account for both debits and lawful entitlements is stronger than one dependent upon unquestioned figures.
This is not about avoiding legitimate debts or taxes. It is about establishing them accurately.
For ordinary New Zealanders, a home may represent decades of work and the largest financial commitment they ever make. Mortgage interest, rates, tax, legal expenses and transaction costs can consume substantial portions of household income and accumulated capital. When financial institutions, councils, lawyers and government agencies interact with that asset, transparency matters.
The principle should run both ways.
If an amount is due, prove it.
If a deduction exists, apply it.
If a credit belongs to the taxpayer, identify it.
If the reconciliation produces a refund, pay it.
That is not avoiding tax. It is doing the tax properly. We_Review_the_Crown_IRD_Review_…
Ten Questions Worth Asking
The investigation now comes down to ten questions:
- What was actually advanced, and where did the money move?
- What exactly does the security secure?
- Was any bill, note or negotiable instrument actually created?
- Who received the economic benefit of the interest?
- What interest and property expenses were claimed, denied or carried forward?
- What GST treatment applied, and why?
- What did the council receive, and how was each rates amount verified?
- What did the bank add to the secured account after default?
- What did the property sale generate, who received each deduction, and what remained?
- What was the final tax position after every legitimate entitlement was included? We_Review_the_Crown_IRD_Review_…
Proof Before Theory
There is an important boundary to this investigation.
We should distinguish documented facts from questions that still require evidence. We should not assume that securitisation, insurance payments, tax credits, bills, notes, refunds or unlawful enforcement exist in an individual case simply because such concepts exist.
Where somebody alleges that they do, the standard should be simple: produce the record and reconcile it. We_Review_the_Crown_IRD_Review_…
That standard should apply equally to the homeowner, bank, council, lawyer and Crown.
Proof first. Full ledger before settlement.
