The garden office part 3: Business ownership

Some garden offices are intended to be used entirely for business and, if so, it’s worth exploring which costs of installation and construction the business can incur without creating tax problems.

Where the garden office pod is purely used for business there is likely to be a much greater desire to achieve the maximum tax benefits for the business. 

Structures and Buildings Allowances 

Could there be any reliefs for the structure itself if it’s owned by the business? 

A garden pod in and of itself falls within the category of a structure for the structures and buildings allowance (SBA) introduced in October 2018. This allows relief at 3% per year on a straight-line basis on the costs of the construction of non-residential buildings. 

However, SBAs are not intended for buildings with residential use. In HMRC’s original technical note from 2018, it stated that “no relief will be provided for work spaces within domestic settings, such as home-offices”. Subsequently, in June 2019, the Government noted that legislation would be introduced to clarify that assets within the curtilage of a residential structure or building would also be excluded.

Thanks and I like your conclusion. The problem is that clients email expecting a yes or no answer and everyone seems to think there are lots of WFH allowances around due to Covid.

I am not sure I follow the BIK. If the company has paid for the pod and it is 100% business use then why is there a benefit?

A pod seen as a building at 3%?

A wooden shed is not going to last 30 years. I do not see it as a building, especially as not permanent (its capable of being dismantled and moved). I suppose if it has plumbing and is build as accommodation (most sheds may not legally be used as accommodation) one could argue but most are just wired for electricity (wifi for broadband).

Councils do not see it as requiring planning permissions as not permanent. The only rule in my area is it must be below 2.3m in max height. Office use is allowed without planning or rates subject to own use not public.

Dual use obviously raises tax issues if claiming it as a business expense.

With WFH becoming big there has to be some flexibility and clarity.

Generally I say, yes you will be a little better off in year one but the BINK erodes this and in due course you will be worse off. ...

Then I give them a help sheet like this but with all the maths in showing why...

Basically this is just a long list of reasons why it is almost always better to pay for a garden office yourself, rent it to your company and claim a reasonable % of council tax and utility bills. You can still buy the furniture/equipment in the company name and claim AIA.

Good to have a checklist of all the reasons why it's usually inadvisable to do it through the company though, just in case clients ask or are difficult to convince. If you can't afford the money and need company funds, borrow them on your loan account. It will be cheaper than a 20% MV BIK.

It would have to be a pretty big and expensive structure to make it worthwhile getting the company to pay, and even then it can be a minefield, as explained above.

Whichever route you take, always ensure business use ceases before you sell the house. PRR on the garden and grounds is not restricted for past use, only for existing use. That's because the relevant clause in TCGA 92 is written in the present tense.
