Q. I'm going to represent my company on an official UK trade mission to Australia, organised by my trade body. It will involve meetings with Australian potential clients over four days in two cities. My wife will accompany me on the trip, but she will not take part in the meetings. We will stay on in Australia to enjoy a short holiday. How should I split the costs between business and personal?

A. Your wife's share of the costs, such as air-fares and hotel bills, are not a business expense, so you need to personally reimburse your company for those costs. Any expenses relating to the holiday part of the trip (e.g. hotel and car hire expenses) should also be borne by you personally, not by your company.

Q. My daughter is now studying at University, but she worked full-time after leaving school in June and had tax deducted from all of her wages. Can she claim that tax back now, or does she have to wait until the end of the tax year?

A. She can claim the tax back now, and doesn't have to wait until the end of the tax year on 5 April 2014 to receive her tax refund. She needs to complete form P50 and send to HMRC.

However, if she expects to work again in the Christmas holidays, she may want to wait until she has completed that stint of work to reclaim all of the tax deducted in one go.

Q. There is an offer in my area to lease an electric car for two years, to help test the electric charging infrastructure installed by the council. Can my company take advantage of the tax breaks if I lease the car?

A. No. If the lease for the car is in your personal name your company cannot claim the 100% capital allowances which are available for electric and low-emissions vehicles. If the car will be used for your business we can help you crunch the numbers to see if it would be worthwhile for your company to purchase or lease the car and claim the allowances. However, from 6 April 2015 there will be a tax charge for your personal use of the electric car.

Q. I formed my new company in November 2012 and my wife (Liz) became a director and employee of that company at that time. Liz is now expecting our first child in August 2013. Can our company pay Liz statutory maternity pay?

A. Unfortunately Liz has not worked for 26 weeks for her employer before the 15 weeks prior to birth, so statutory maternity pay is not due. There is nothing to stop your company from paying Liz her normal wages while she is on maternity leave, but as those wages do not amount to statutory maternity pay the company can't reclaim that pay from the tax office.

Q. I am a non-executive director of a number of companies. Can I offer consultancy services to those companies on a self-employed basis?

A. You can offer your services to those companies on a self-employed basis, but you need to have a clear contract which distinguishes your work as a consultant from work you do as a director. The self-employed tasks need to be invoiced separately and declared to HMRC as a separate business from your fees as a director.

Generally the fees for work you perform as a director should be taxed under PAYE. Legislation introduced in the Finance Act 2013 requires the IR35 provisions to apply to work done as officers where that work is charged through a third party, such as a personal service company.

Q. I am thinking of investing some money in premium bonds. Are there any tax advantages or disadvantages?

A. You won't receive interest on the money held in premium bonds but any prizes you receive from those bonds are tax free. The prize fund is calculated on the basis of a nominal interest rate of 1.3%. Thus if you hold £10,000 in premium bonds for one year, on average you should expect to win £130 as bond prizes over the year. However, that return is not guaranteed and you may win more or less. You could also win the big prize of £1million!

The premium bonds will form part of your estate for inheritance tax purposes, so will be subject to inheritance tax on your death if the value of your total estate exceeds the exempt limit of £325,000 (fixed to 2018).

Q. I run my own consulting company in the UK, which pays my Brazilian wife a small wage for answering the phone and preparing marketing materials. Can the company pay for her to complete an advanced English course at the local college?

A. Training for any employee can be charged through the company if it is relevant to the employee's duties or future duties. An ability to speak and write correct English is necessary for your business so the proposed English course is work-related training for your employee. Your company can pay for the course, and receive a tax deduction for that cost. There will be no benefit in kind charge for your wife. The company can also pay for travel to the course. You should list the duties your wife performs for the company, and both sign the document as part of her employment terms with the company. This description of her duties will justify the training cost, should the Taxman ever ask.
