Have you got a cabin in your garden?
Are you thinking of using it as a home office?
Will you and your family also use it for private purposes?
Will it be more tax efficient for you or your company to pay for it?
Your company may provide you with assets such as a computer (or a garden office!) for the purpose of working from home. It will not be a taxable benefit if there is minimal private use, however, if there is significant private use, it will be a taxable benefit.
But what will the taxable amount be? Well, this depends on 2 factors; the cost of providing the asset and any additional expenses (maintenance etc). For example, you have a garden office which costs £25,000 to install. The taxable benefit is 20% a year, so £5,000 each year. If it is used for 15 years (15 x £5,000) you will be taxed on £75,000! Your company may also be paying Class 1A NI on the same amount, so if you are a higher rate taxpayer for the 15 years (and assuming tax/NI rates stay the same!) the tax and NI cost would be £40,350 ((£75,000 x 40%) + (£75,000 x 13.8%)).
But remember, if the garden office was rented or leased, the taxable benefit will not be 20% of its cost but the amount of rent paid. It doesn’t matter how many days you use it- this will not reduce the taxable benefit!
Rather than make an asset (garden office) available to a director or employee for long-term use, the NI cost can be reduced if a dividend is paid. Therefore, it would be more tax and NI-efficient to pay a dividend to enable the purchase!
