Q. I was travelling abroad on business last month when I got terrible tooth ache. I sought emergency treatment at a local dentist and paid the bill using my company's debit card. Will I be taxed on the dentist's fee as a benefit in kind?

A. If the dental cost had been incurred while you were in the UK, it would have been a taxable benefit for you. But as you were working outside the UK at the time, your company can pick up the bill with no tax cost to you. The dental bill is also a valid deduction for the company as it forms part of the cost of sending you to work abroad for a short period.

Q. Private school fees are so expensive, can I get my company to pay the fees directly and save myself a bit of tax?

A. If the company pays a bill, such as the school fees, which you are personally liable to pay, the payment is treated for national insurance (NI) purposes, as if the company had paid it to you so the company must pay employers NI on top of the amount of the fee. However, it is a benefit in kind so it must be reported on the form P11D and the income tax you are due to pay will be included in your PAYE code for the next year. In the long run you don't save any tax or NI.

If your company contracts directly with the school to be the person responsible for paying the school fees, the tax position is slightly different. The payment must be treated as a benefit in kind and reported on your form P11D, and the company must pay class 1A NICs on the amount paid. You pay tax on the payment to the school, but not NICs.

Q. My personal service company is about take on an IT servicing contract in Belgium. The customer will pay me a rate for every day I attend their premises, on top of my fee for the whole contract. This 'per diem' rate is less than HMRC's benchmark rate for expenses when working in Belgium. Can it be paid directly to me personally or should it be paid to my personal service company?

A. The 'per diem' rate should be paid to your company and be included in its turnover for VAT purposes, so treat it as a gross receipt including VAT. Your company can pay you expenses for working abroad, at or below the HMRC agreed benchmark rates. Do not short circuit this by accepting the per diem rate straight into your personal bank account as this will create a VAT mess.

Q. I work as a self-employed courier for a large courier company who operates self-billing for VAT purposes and pays me monthly. I have just registered for VAT which has been back-dated to 1 May 2014. What should I do to collect the VAT due for May, June and July?

A. You should ask your customer if it is acceptable for you to issue a VAT only invoice to them. Calculate the VAT due as if the total amounts you have received in May to July under self-billing are the net amount of your fees for the period. You should also supply your customer with a copy of your VAT registration certificate, so the company knows to add VAT to your self-billing invoices in the future.

Q. In July 2011 I sold a property which had been used for my business. I planned to reinvest the proceeds in another property, but that acquisition never happened. I know I should now pay Capital Gains Tax on the gain made in July 2011. How do I go about doing that?

A. The period in which you should have reinvested the proceeds ran out in July 2014, so you do need to pay the CGT due for 2011/12 unless you get the tax inspector to agree to extend the period for reinvestment. He will only agree to an extension if you were prevented from reinvesting by circumstances beyond your control.

The disposal made in July 2011 should have been reported on your 2011/12 tax return as part of your provisional claim for roll-over relief. You should now write to the tax office to withdraw that provisional claim and declare the full taxable gain. The tax will be payable immediately and interest will run from 31 January 2013.

Q. I do some educational consultancy work in Africa for a business based in Ireland. My UK-based company will issue the invoice for that work, but it's in the flat rate scheme for VAT. Should that invoice be included in the turnover I apply the flat rate to?

A. The invoice your UK Company sends to Ireland for your work in Africa is outside the scope of VAT. You should not add VAT to that invoice, and you should exclude that invoice from the turnover used to calculate your flat rate payment of VAT for the quarter.

Q. I am thinking of selling a flat that has been let since I acquired it in 2012. I do not own another property. My tenant is moving out soon, after which I will either stay in it myself or sell it. Will I get lettings relief to reduce the capital gains tax (CGT) payable?

A. Lettings relief only applies if you have lived in the property as your main home for some period. So if your tenant moves out and you sell the property immediately you will not get lettings relief, or any relief from CGT, other than the annual exemption.

However, if you move into the property and make it your own home, the gain relating to your period of occupation will be free of CGT. The last 18 months of ownership will also be free of CGT even if you are not living in the property during that period. The total gain on sale can also be reduced by lettings relief, which is limited to the lowest of these three amounts:

- the part of the gain which is exempt because the property was your main home;
- the gain attributed to the period it was let; and
- £40,000.

There are thus large tax savings to be made by occupying the property as your main home, but you must show that you intended the property to be a permanent residence, not a temporary occupation while the property was on the market. It is the quality of occupation not the length of time that demonstrates the property was your main home.
