What is Ontario land transfer tax (LTT)?

Ontario land transfer tax is a tax typically payable when property changes ownership. It is commonly calculated based on the purchase price and is usually paid on closing.

Does land transfer tax apply when buying a lot to build on?

In many cases, yes. If you purchase land (a lot) and take title, land transfer tax can apply to that purchase. Budgeting correctly means separating land acquisition costs from construction costs.

How do I estimate land transfer tax for budgeting?

Use a reliable calculator and confirm details with your lawyer based on your exact scenario (location, whether you are a first-time buyer, and the type of property).

Ontario Land Transfer Tax for Custom Home Buyers: What to Budget Before You Build

TL;DR: Land transfer tax is usually a land-acquisition cost, not a construction cost. If you are buying a lot before building custom, it needs to be part of the land budget from the beginning.

This article is general information only and not legal or tax advice. LTT rules can change and can depend on your specific scenario. Confirm details with your lawyer.

What LTT is (in plain English)

Land transfer tax is a tax that commonly becomes payable when a property changes ownership. In many transactions it is paid at closing as part of your total closing costs.

Why it matters for custom builds

Custom builds often involve two big buckets:

Land acquisition (buying the lot)
Construction (building the home)

LTT is generally tied to the land acquisition step when you take title to the property. That is why new-build budgeting needs to keep land and construction separate.

Special note if you are buying in Toronto

Some municipalities can have additional land transfer taxes. If you are buying in the City of Toronto, do not assume the provincial calculation is the full story. Confirm the closing-cost picture with your legal team before you finalize the deal.

How to estimate it the right way

Because rates and rebates can change, the safest approach is:

Estimate using a calculator that is kept up to date.
Confirm the result with your lawyer based on the exact property type and location.

Our Ontario Mortgage Calculator is built to help you understand the bigger picture, but land transfer tax should still be confirmed with your lawyer based on the exact transaction.

Budgeting tip: do not underestimate closing costs

Even strong budgets get stressed when closing costs are not planned for. LTT is one line item, but it is often a big one. The earlier you model it, the cleaner your decisions will be on the construction side.
