How can I gift my assets to my children to avoid IHT?

It is possible to gift a buy to let property investment to a child. You may pay Capital Gains Tax (CGT) when passing a buy to let property to a child. However, using a trust wrapper allows you to use your IHT lifetime allowance rather than being charged CGT. See the article for more details: https://www.optimiseaccountants.co.uk/gifting-buy-to-lets-properties-to-children/. Our accountants for property investors can help you reduce tax too.

How do I transfer a property into a limited company?

Landlords want to use a property investment company as it saves tax. It makes sense that those landlords also want to transfer their existing property portfolio into a property investment company.

Transferring properties to a limited company from your personal name will on the majority of occasions incur a Capital Gains Tax (CGT) charge on you as the seller. You will also have a Stamp Duty Land Tax (SDLT) charged by the purchasing limited company. Both of these may be avoided using the incorporation reliefs of moving properties to a limited company via a partnership. Read our article here: https://www.optimiseaccountants.co.uk/transfer-properties-to-a-limited-company/ Our peorpty accountants have helped hundreds of landlords transfer property to a limited company without paying excessive tax.

How does Section 24 (mortgage interest relief) affect my tax position?

Section 24 mortgage interest relief cap started to come into effect 2017/18 with the reduction of 25% to the amount of mortgage interest that is allowed to be offset against your property income. From 2020/21 landlords will no longer be able to offset mortgage interest against their property income. This means that the majority of landlords will pay more tax. In this article, we explore what Section 24 is, how it will affect you as a property investor and what may be done to mitigate its effect.

A lot more landlords are now using property investment companies to save tax. This is one of the reasons why many landlords use our property accountants.

How do I extract cash out of a limited company in the most tax efficient way?

There are many ways in which you can extract money from a limited company. The most obvious ones are wages and dividends. However, there are many golden nuggets that may be extracted from your limited company gold mine. The tax you save using a property accountant will be significantly more than the cost. Our property tax accountants are here to help you extract cash out of a limited company in the most tax-efficient way.

When does Stamp Duty Land tax apply to property developers and when doesn’t it?

Stamp Duty Land Tax (SDLT) is a tax that is paid by property investors and developers when a property is purchased. There is also the new 3% SDLT surcharge that applies to residential property investments. However, like many taxes SDLT is optional. As a property developer, it is possible not to pay SDLT on residential property investments. In this article, we explore the many ways in which SDLT may be avoided altogether: https://www.optimiseaccountants.co.uk/developers-do-not-pay-sdlt-on-flips/


SDLT can be tricky for landlords using property investment companies. Use our property accountants to ensure this is done rigth.
