Principalresidence

A principal residence is the home where a person lives most of the time, as distinct from holiday homes or investment properties. Many tax systems give special treatment to the sale of a principal residence, such as exempting some or all of the profit from tax.

The exact rules and conditions vary by country.

From the Money Master HQ dictionary, founded by Shihan Sheriff (FCMA, VP of Finance at Nomod, CFO at Esanjo Ventures). How these definitions are written.

What it means

Your principal residence is normally the home you use as your main base, where you spend most of your time and where your daily life is centred. Evidence includes where you are registered to vote, where you receive mail, where your family lives and where you work.

A person can own several properties but usually has only one principal residence at a time. The label matters mainly for tax and lending.

Governments often want to encourage home ownership and avoid taxing people on gains from the home they live in. As a result, selling a principal residence frequently attracts a lower tax bill than selling an investment property of the same value.

Typical conditions include having owned the property and lived in it for a minimum period before the sale, and limits on how often the relief can be claimed. Some systems cap the amount of gain that is exempt, and others exempt the whole gain.

A person who rents out the home or uses part of it for business may lose part of the relief. Lenders also care.

Mortgages on a principal residence usually carry lower interest rates and lower deposits than loans for investment properties, because borrowers tend to look after their own home and prioritise its payments. A borrower who claims a property as a principal residence when it is really a rental can face serious consequences for misstatement.

Finance professionals and business owners should keep good records. Purchase price, legal costs, improvements and selling costs all affect the gain, and evidence of where you lived may be needed to support a claim.

This entry gives general information only, and local rules should be checked with a qualified adviser. Moving house raises its own questions.

Some systems let owners defer or roll over gains if they buy another home within a set period, while others simply exempt the gain up to a limit. Timing a sale and a purchase to fit the rules can make a visible difference to the tax bill.

In practice

Real-world examples.

1

Example

A couple sells the home they have lived in for twelve years and moves to a smaller property. Because it was their principal residence, most or all of their profit is tax-free under their country's rules. They keep the sale documents in case the tax authority asks for them later.

2

Example

An executive buys a flat to rent out and a house to live in. Only the house counts as her principal residence, so a sale of the flat would be taxed on any gain. She also tracks the cost of improvements to the flat to reduce any future gain.

3

Example

A freelance designer uses a spare room of her home exclusively as an office. Her accountant advises her that part of the gain on a future sale may not qualify for the relief.

Formula

Calculation

Gain = Selling price - Selling costs - Purchase cost - Improvements, and Taxable gain = Gain - Exemption available. A homeowner buys a house for $400,000 and later spends $50,000 on a new kitchen and extension. She sells it for $750,000 and pays $45,000 in agent and legal fees. The gain is $750,000 - $45,000 - $400,000 - $50,000 = $255,000. Assume her country exempts the first $250,000 of gain on a principal residence. The taxable gain is $255,000 - $250,000 = $5,000, and tax is charged only on that amount at the rate that applies. Without the relief, tax would apply to the whole $255,000.

Case study

Seen in the real world.

Hollis Family is a fictional household that moved abroad for work and rented out their house for six years before returning. When they decided to sell, they assumed the whole gain would be tax-free because it had been their home for most of the time.

Their adviser explained in this illustrative case that the rules reduced the relief for the years it was rented out, so part of the gain was taxable. Records of the dates they lived in the property and the rental income were needed to work out the split.

Because the family had kept clear paperwork, the adviser could calculate the correct taxable portion and file accurately. The fictional story shows that the principal residence label can be partly lost by changes in use.

Watch out

Common mistakes.

  • Assuming any home you own qualifies, when only the property you actually live in as your main home normally does.
  • Ignoring rental or business use, which can reduce the relief.
  • Throwing away records of improvements and costs, which reduce the taxable gain.

Questions

People also ask.

Can I have two principal residences?

Usually not at the same time, because the relief is designed for a single main home.

Is the relief the same in every country?

No, the conditions, time requirements and limits differ, so check the local rules.

Does it affect mortgages?

Yes, lenders typically offer better terms for a home you live in than for an investment property.
