Don't mention the word avoidance around these parts!!
People don't avoid tax they simply, do something which allows them to claim tax relief!!!
Section 48 properties were built under the Seaside Resorts tax incentive scheme, which was introduced thirteen years ago and which aimed to stimulate development in certain coastal towns and villages.
Investors who acquired Section 48 holiday homes could offset the cost of the property against all their income, on condition that they made them available for rent by tourists for 10 years.
Section 48 was to the vast majority of investors a failure. I assume that any relief which may be brought in will be fully section 23 type.
