The chancellor Rishi Sunak is said to be considering proposals by the Office of Tax Simplification (OTS), a Treasury-based body, to reform capital gains tax in light of the economic and fiscal impact of the Covid-19 crisis, signalling future raid on second homeowners, including buy-to-let landlords, but this could potentially have an adverse impact on the private rented sector.

The government’s tax adviser recently recommended that capital gains tax be overhauled with proposals that could see the number of people hit by the duty rise significantly.

The move has the potential to bring in an extra £14bn by reducing exemptions and doubling rates, according to the review, which was commissioned by the chancellor.

However, the chancellor’s plans could cause homebuyers, investors, and landlords to exit the market if there is a major increase in CGT in the near future, a fresh report shows.

The study found that over half of landlords are considering divesting their portfolios and leaving the PRS due to an increase in regulation and rules, which would dramatically reduce the supply of much needed privately rented homes.

Recent tax hikes, including stamp duty changes on buy-to-let and the loss of tax-free allowances, are driving away landlords and crippling the sector.

Regulatory tax changes, along with high maintenance costs have all been identified as the main barrier posing a threat to their buy-to-let investments.

“The Covid-19 pandemic has had a huge impact on the lettings sector, said Aaron Short, founder and CEO at Accommodation.co.uk, which conducted the survey.
