Free NSW Settlement Adjustment Calculator: Verify Your Statement Before Settlement (2026 Guide)

Settlement adjustments are the small numbers that decide whether you pay an extra $300 or an extra $3,000 at completion. On a typical Sydney property purchase, total adjustments sit between $400 and $2,500. Get the calculation wrong, and that money flows in the wrong direction. Once funds are released at settlement, recovering them is expensive and slow.

This page gives you a free calculator built specifically for NSW law, a downloadable statement template Sydney conveyancing lawyers actually use, and a clear walkthrough of how the figures should be calculated. If you are buying or selling a property in NSW and want to verify the figures your conveyancer has produced, you are in the right place.

What Is a Settlement Adjustment in NSW?

When you buy a property in NSW, certain ongoing costs are paid in advance or arrears for billing periods that do not line up with your settlement date. Council rates, water charges, and strata levies all run on quarterly cycles. Settlement adjustments split these costs fairly between buyer and seller based on the days each party owns the property within that period.

The buyer is treated as responsible from the settlement date onwards under the standard 2019 NSW Contract for the Sale and Purchase of Land. The seller is responsible for the period before settlement. Each line item is calculated separately, then totalled into a single net figure that adjusts the settlement amount.

What Gets Adjusted at NSW Settlement

Five categories typically appear on a NSW statement of adjustments:

Council rates: Issued in a Section 603 Certificate by the local council under the Local Government Act 1993 (NSW). Most NSW councils bill quarterly. The certificate is valid for 90 days from issue.
Water rates and service charges: Sydney Water (or your local water authority) issues a Section 66 Certificate showing fixed service charges and any outstanding amounts. Service charges are adjusted pro rata across the billing period.
Water usage: Variable charge based on actual meter readings. A special meter read is ordered close to settlement (around $30 to $50). Usage up to settlement is the seller’s responsibility.
Strata levies: For strata-titled properties only. The Section 184 Certificate (formerly Section 109) discloses current admin fund levies, capital works fund levies, special levies, and the financial position of the owners’ corporation.
Land tax: Adjusts only if the contract specifically allows it. The standard 2019 NSW contract excludes land tax adjustment unless box 16 is ticked.

If the property is tenanted, rent and rental bond also adjust. This is less common in residential sales.

How Settlement Adjustments Are Calculated

For each pro-rata item, the calculation follows the same formula:

Daily rate = Total amount for the billing period divided by the number of days in that period
Buyer’s share = Daily rate multiplied by the number of days from the settlement date to the period end
Seller’s share = Daily rate multiplied by the number of days from period start to the day before settlement

If the seller has paid the bill, the buyer reimburses the seller for the buyer’s share. If the bill is unpaid at settlement, the seller credits the buyer for the seller’s share. The calculator handles both directions automatically.

Worked Example: $1.2M Chatswood House

Settlement date: 15 August 2026

Property: Standalone house in Chatswood (no strata)

Item	Amount	Period	Status
Council rates Q3	$600	1 Jul to 30 Sep (92 days)	Paid by the seller
Water service charge Q3	$280	1 Jul to 30 Sep (92 days)	Paid by the seller
Water usage in the settlement	$145	To 15 Aug	Unpaid

Council rates calculation:

Daily rate: $600 divided by 92 days = $6.52
Buyer’s days (15 Aug to 30 Sep, inclusive of settlement): 47 days
Buyer reimburses seller: $6.52 x 47 = +$306.52

Water service charge calculation:

Daily rate: $280 divided by 92 days = $3.04
Buyer’s days: 47 days
Buyer reimburses seller: $3.04 x 47 = +$143.04

Water usage:

Unpaid amount accrued during seller’s ownership
Seller credits buyer: -$145.00

Net adjustment: $306.52 + $143.04 – $145.00 = +$304.56

The buyer transfers an additional $304.56 to the seller at settlement, on top of the contract balance.

7 Settlement Adjustment Errors That Cost NSW Buyers Money

Even experienced conveyancers miss these under settlement-day pressure. If you are verifying a statement your conveyancer has produced, check for each:

Outdated Section 603 Certificate – The certificate is valid for 90 days. If ordered too early, the next quarter’s rates may have been issued, and your figures are stale.
Missing special strata levies – Special levies struck between the certificate date and settlement may not appear unless the certificate is updated. Special levies for building works can run into thousands.
Water usage is estimated rather than read – When no special meter read is ordered, conveyancers sometimes estimate from prior bills. If actual usage is higher, the seller is under-credited.
Wrong day count methodology – The standard 2019 NSW contract treats the buyer as responsible from the settlement date onwards. Generic spreadsheet templates often get this wrong, costing one party a day’s worth of charges across every line item.
Land tax is adjusted when the contract excludes – Always check whether box 16 of the contract is ticked before agreeing to a land tax adjustment in the statement.
Unpaid council rates not properly handled – If rates are unpaid at settlement, the unpaid amount should be paid directly to the council from settlement funds, or the seller credits the buyer for the full amount. The buyer should never inherit unpaid rates without offsetting credit.
Special meter read fee charged to the buyer – The fee for the special water read relates to closing out the seller’s account. It is the seller’s cost. Sometimes appears on the buyer’s side of the statement.

CASE STUDY: Strata Apartment, Disputed Special Levy

Client situation: A buyer purchasing a $980,000 strata apartment in North Sydney was sent a statement of adjustments showing a $4,200 special levy charge as the buyer’s responsibility. The Section 184 Certificate had been ordered 75 days before settlement; the special levy had been struck by the owners’ corporation 10 days before settlement.

Our approach: We reviewed the contract, the original Section 184 Certificate, and the owners’ corporation minutes. The special levy had been struck after exchange, and under the contract terms in this matter, the seller was responsible for any levies struck before settlement that were known to them. We requested an updated Section 184 Certificate showing the levy and the strike date, then issued a notice to the seller’s lawyer requiring the figure to be moved to the seller’s side of the statement.

Result: The seller’s lawyer agreed within 24 hours rather than risk a settlement dispute. The buyer saved $4,200 at settlement on a charge that should never have been on their side of the statement in the first place.

Who Prepares the Statement of Adjustments?

Standard practice in NSW: the buyer’s lawyer or conveyancer prepares the draft statement and sends it to the seller’s lawyer for review and agreement, typically 5 to 7 days before settlement. The seller’s lawyer either confirms the figures or proposes amendments. The parties resolve any differences and sign off before settlement proceeds.

The buyer is in a stronger position when their own lawyer prepares the draft. It sets the methodology and the supporting certificate dates that the seller has to argue against, rather than the other way round. If you are buying without a lawyer, this is the single most important reason to get one involved before settlement.

NSW Certificates Required for Settlement Adjustments

Certificate	Issued by	What it covers	Cost
Section 603 Certificate	Local council	Council rates, charges, and land restrictions	$90 to $140
Section 66 Certificate	Sydney Water / local water authority	Water rates, service charges, sewer encumbrances	$40 to $60
Section 184 Certificate (strata)	Owners corporation	Strata levies, special levies, OC financials	$123 (statutory)
Special meter read	Sydney Water	Final water usage at settlement	$30 to $50

Your lawyer or conveyancer orders these on your behalf as disbursements. The total certificate cost on a typical NSW conveyance sits between $260 and $370 for a non-strata property and $380 to $490 for a strata property.

When You Should Have a Lawyer Verify Your Statement

You can review your own statement if you are confident with the formulas. That is why this calculator exists. But three situations always warrant a lawyer’s eyes on the figures:

Strata properties. Section 184 certificates contain critical disclosures beyond levies. Errors or omissions here regularly cost buyers tens of thousands of dollars after settlement.
Settlement near a new billing period. When settlement falls within a few days of a new quarter, multiple billing periods overlap and complexity multiplies. This is where most disputed adjustments arise.
Disputed figures. If the seller’s lawyer pushes back on your statement, having a lawyer represent your position is the difference between holding firm and conceding money you do not owe.

FAQs: NSW Settlement Adjustments

What is a settlement adjustment sheet?

A settlement adjustment sheet, also called a statement of adjustments, is the document that splits property-related costs between buyer and seller based on the settlement date. It covers council rates, water charges, strata levies if applicable, and any other adjustable amounts under the contract. The result is a single figure added to or subtracted from the settlement amount transferred at completion.

How Settlement Adjustments Are Calculated

How are settlement adjustments calculated in NSW?

Each adjustable cost is divided by the number of days in its billing period to give a daily rate. The daily rate is multiplied by the days each party owns the property within that period. The buyer is treated as responsible from the settlement date onwards under the standard 2019 NSW Contract for the Sale and Purchase of Land.

Who prepares the statement of adjustments in NSW?

The buyer’s lawyer or conveyancer prepares the draft and sends it to the seller’s lawyer for review, typically 5 to 7 days before settlement. Both parties sign off before settlement proceeds.

What is a Section 603 Certificate?

A Section 603 Certificate is issued by the local council under the Local Government Act 1993 (NSW). It shows current council rates, payments made, outstanding amounts, and any restrictions on the land. It is mandatory for calculating settlement adjustments and is valid for 90 days from issue.

Does land tax adjust at settlement in NSW?

Land tax adjusts only if the contract specifically allows it. The standard 2019 NSW Contract for the Sale and Purchase of Land excludes land tax adjustment unless the parties opt in (box 16 on the contract front page). If your contract excludes it, you should not be charged a portion of the seller’s land tax in the statement.

Can settlement adjustments be disputed?

Yes. If you disagree with the figures, your lawyer raises the issue with the seller’s lawyer before settlement, and the parties negotiate the correct amount. Common grounds include outdated certificates, estimated water usage, day count errors, and items adjusted that the contract excludes.

What happens if council rates are unpaid at settlement?

If rates are unpaid as at settlement, the unpaid amount should be paid directly to the council from settlement funds, or the seller should credit the buyer for the full outstanding amount. The buyer should not inherit unpaid rates as a personal debt.

Is there a free settlement adjustment calculator for NSW?

Yes, we provide a free NSW settlement adjustment calculator on this page. It handles council rates, water service charges, water usage, and strata levies, and produces a downloadable statement template. For complex matters, have a Sydney conveyancing lawyer verify the result before settlement.

How is settlement adjustment in NSW different from other states?

Each state uses different certificates and methodologies. Western Australia uses different forms and water authority structures. Victoria’s Section 32 disclosure operates separately from the adjustment process. Queensland has its own rates certificate regime. This calculator is built specifically for NSW.

Can I prepare my own statement of adjustments?

Resolution time depends on how early legal advice is sought and how willing the other party is to engage. Disputes resolved through a formal legal letter followed by negotiation can be concluded in weeks to months. Disputes that proceed to a section 232 oppression application in court typically take between 12 and 24 months to reach a final hearing, though many settle before that stage. The earlier legal advice is obtained, the more options are available and the shorter the likely resolution timeline.
