What closing costs are tax deductible in Ontario?

Summary: Most closing costs on a home you live in are not tax deductible. They are added to the property's adjusted cost base instead, which usually does not matter because of the principal residence exemption. On a rental or investment property the rules change: some costs are deductible and others are added to your cost base.

What does "tax deductible" actually mean here?

A tax deduction lowers the income you pay tax on. It is different from a tax credit, which reduces the tax you owe directly, and from your adjusted cost base (the total cost of a property, used to calculate your capital gain when you sell). Whether a closing cost helps you depends on which of those three buckets it falls into.

For closing costs, the deciding factor is whether you bought the property to live in or to earn income. The same legal fee is treated one way on your own home and another way on a rental. So the honest answer to "are closing costs deductible" is: rarely on your home, sometimes on an investment property.

Are closing costs deductible on a home you live in?

No. When the property is your principal residence, you cannot deduct land transfer tax, legal fees, title insurance, or a home inspection. The Canada Revenue Agency treats these as personal, capital costs of buying a home, not expenses you incurred to earn income.

Those costs are added to the home's adjusted cost base, which only matters if you later sell at a gain. For most homeowners the principal residence exemption cancels that gain, so the cost base never comes into play. The real tax relief for buyers is not a deduction at all:

• The Home Buyers' Amount. A federal non-refundable tax credit worth up to about $1,500 for eligible first-time buyers. It reduces tax owing; it does not deduct your closing costs. See the CRA Home Buyers' Amount page.

• The GST/HST New Housing Rebate. Available on many new builds and substantial renovations, claimed through your builder or directly. Again, it is a rebate, not a deduction.

Which closing costs are deductible on a rental or investment property?

On a property you buy to earn rental income, the costs split in two. Money spent to acquire the property is a capital cost added to the adjusted cost base. Money spent to finance the purchase or to operate the rental is deductible, either over five years or right away.

The pattern is consistent: acquisition costs lower a future capital gain, financing costs are deductible over time, and ongoing operating costs are deductible in the year you pay them. The CRA's rental income guide (T4036) walks through each category.

How should you track closing costs for tax time?

Keep every closing document, because the figures feed either your adjusted cost base or your rental deductions, sometimes years after the purchase.

1. Save the statement of adjustments and your lawyer's invoice. They itemize land transfer tax, legal fees, title insurance, and disbursements in one place.

2. Record the adjusted cost base from day one. Start with the purchase price and add the eligible closing costs, so a future capital gain is easy to calculate.

3. Separate personal use from income use. If a property changes from your home to a rental, the tax treatment of its costs changes too, and your accountant will need the split.

4. Confirm the treatment before you file. Tax rules turn on small facts, so check the current CRA guidance or ask an accountant rather than assuming.

Frequently asked questions

Can I deduct land transfer tax in Ontario?

Not on a home you live in. On a rental property, land transfer tax is a capital cost added to the property's adjusted cost base, so it lowers your capital gain when you sell rather than reducing the income you pay tax on today.

Are legal fees for buying a house tax deductible?

For a principal residence, no. For a rental, legal fees to buy the property are added to the cost base, while legal fees arranging the mortgage count as financing costs and are deducted over five years.

Is the first-time home buyer tax credit a deduction?

No. The federal Home Buyers' Amount is a non-refundable tax credit worth up to about $1,500, not a deduction of your closing costs. It reduces tax owing directly if you qualify.

Do closing costs lower my capital gains tax when I sell?

They can. Adding eligible closing costs to your adjusted cost base reduces a future capital gain. For a principal residence the gain is usually exempt, so this matters most for rentals, cottages, and other investment properties.

Can I deduct closing costs if I work from home?

No. Business-use-of-home rules let you claim a share of ongoing costs like utilities and property tax, but the one-time costs of buying the home stay capital and are not deductible.
