Filling out your personal tax return
Definition of an extension
An extension means something physically added onto the property.
This includes the construction of a:
- loft extension (if the roof line is extended)
Any part of a loan for home improvements or interior alterations can't be claimed.
Phasing out interest tax relief for your main residence
From the year of assessment 2017 the interest cap is reducing by £1,500 per annum until the interest relief is nil for the year of assessment 2026.
How interest relief on your main residence works
The interest is a deduction against your income at the marginal rate calculation of tax.
You can claim this tax relief for the purchase or extension of your main residence in Jersey.
This must be a house or flat. It does not include boats or caravans etc.
When interest tax relief is calculated, we take into account the following:
- the relief is only given using the marginal tax calculation
- there is a capital restriction of £300,000
- the maximum interest given is £15,000 up to 2016
- interest relief for your main residence is reducing to nil over 10 years between 2017 and 2026
- any restrictions are calculated on the total borrowing, not on each individual loan
- you must live in the property on a full-time basis
You’ll only receive mortgage interest tax relief if your lender has a source of Jersey mortgage income or profits chargeable to tax in Jersey.
Interest paid on mortgages held by share transfer will be granted tax relief if the conditions above are met.
You take out a loan for £350,000 with a Jersey bank to purchase your home in Jersey. The interest rate on your mortgage is 3%.
At the end of the year the bank sends you a certificate of interest paid (R62) showing interest charged and paid of £10,500 and a year-end capital balance of £345,000.
Interest relief will be calculated as follows:
£300,000 / 345,000 x £10,500 = £9,130
Interest relief that will not be given
Mortgage interest relief will also be restricted if:
- any part of a mortgage or re-mortgage that does not relate to the purchase or extension of your main residence in Jersey
- certain transactions between connected parties, eg a husband or wife ‘selling’ a house with no mortgage to the other and taking out a mortgage in the process for the purpose of gaining interest tax relief, while spending the money elsewhere, will not qualify
- we’ll challenge any tax relief applications if the loan has an artificially inflated rate of interest on capital over £300,000
Interest tax relief for the purchase or extension of a let property
The interest can be claimed as an expense against the letting income on loans used for:
- buying land or property which will be commercially let
- extending a commercially let property
There is no capital restriction on the interest deduction.
Interest tax relief for business purposes
Interest tax relief will also continue to be given for interest incurred for the following purposes:
- interest on loans used entirely and exclusively for earning the profits of a trade, profession or vocation
- interest on loans used for acquiring capital items used by an employee wholly and exclusively in earning the profits and earnings of an employment or office
- interest on loans used for acquiring, in whole or in part, a trade, profession or vocation, or the share capital of a trading company, whether in Jersey or elsewhere
