I've always calculated my business income for a full year to 30 April. Have I been doing it wrong for 20 years?

Q. I've always calculated my business income for a full year to 30 April. On my tax return for 2010/11 I've recorded my business profits, income and expenses for the year to 30 April 2010. But when I rang the Tax Office with a query the adviser told me that my accounts should always be drawn up to 5 April. Have I been doing it wrong for 20 years?

A. The adviser at the tax office is wrong. You can draw up your business accounts to any date you please. The year end of 30 April gives you a long delay between the end of your accounting year and the date on which you need to pay tax on the profits for that period.

I received a letter asking for a payment of £320 to register the company on the 'Intercom VAT Registry'. Should I pay this fee?

Q. I received a letter yesterday addressed to my new company, asking for a payment of £320 to register the company on the 'Intercom VAT Registry'. Should I pay this fee? Is it compulsory?

A. Do not make any payment or respond to this letter. It is a known scam. The 'Intercom VAT Registry' does not exist and it is not an official EU body as the letter suggests. If you are ever suspicious about letters or emails your business receives, check them against the list of known fraud on the Action Fraud website: http://www.actionfraud.org.uk/. We are more than happy to check any suspicious correspondence you receive, so contact us if you are unsure of the legitimacy of any letters or emails sent to you.

I thought each employee could have one tax-free mobile phone, so why am I taxed on my only mobile phone?

Q. My employer has given me a form P11D, which shows that I am taxed on the cost of my smart phone. I thought each employee could have one tax-free mobile phone, so why am I taxed on my only mobile phone?

A. Tax Officials think smart phones are computers rather than phones, so don't want to apply the 'one free mobile per employee' rule, when the mobile phone is a smart phone. However, this can work in your favour if the private use of the smart phone provided by your employer is insignificant. Where any computer equipment is provided to you solely for work purposes, and there is no significant private use, there should be no tax charge. This tax-free treatment doesn't apply where the contract for the mobile phone is in your own name and not the company's name. In that case, where your employer pays for your smart phone the cost is taxed as if it was part of your salary. To remedy this, make sure your next smart phone contract is made between your employer and the telephone provider and you are not a party to that contract.

How should I treat this sum for tax purposes?

Q. My cafe was badly damaged in the recent riots, but my loyal customers have collected £3,000 to help me open the business as quickly as possible. How should I treat this sum for tax purposes? Is it a personal gift, or a contribution to be set against my repair costs?

A. The taxman would view that this gift from your customers should be treated as income for your business for income tax or corporation tax purposes. You are likely to have a lot of repair expenditure to set against your income for the current period, so you may well not have a profit to declare even after including the gift as income.

Can I reclaim the excess tax deducted from my severence pay?

Q. On 15 April 2011 I received severance pay of £80,000 equal to my annual salary, but I was surprised that £23,000 was deducted as tax. I was led to believe the first £30,000 would be tax free and the rest would be taxed at 20%. Can I reclaim the excess tax deducted?

A. It is likely that the first £30,000 of your severance award was tax free, if it was a genuine redundancy payment. This is not always the case as a number of strict conditions must be met.

In the past when such severance payments were paid after the individual had received their P45 form, a BR (basic rate) tax code was applied to the payment which meant only basic rate tax at 20% was deducted. However, since 6 April 2011 employers are required to apply an OT tax code on a month 1 basis to such severance payments. This means that tax is deducted at the basic, higher and additional rates without the benefit of the personal allowances. The month 1 basis means only 1/12 of the basic rate and higher rate limits for the year are taken into account.

The taxable part of your severance payment (£50,000) would have generated a tax deduction of £23,166 using an OT code as follows...

Basic rate: 35000/12 = 2916.67 x 20% = 583.33
Higher rate: 115,000/12 = 9583.33 x 40% = 3833.33
Additional rate: (50,000-9583.33-2916.67) x 50% = 18,750.00
Total = £23166.66
You can reclaim the excess tax charged in your tax return for 2011/12.

Help! I've received two tax calculations from the Taxman that say I owe £4,500 for 2007/08 and £7,200 for 2008/09. What should I do?

Q. Help! I've received two tax calculations from the Taxman that say I owe £4,500 for 2007/08 and £7,200 for 2008/09. I didn't complete tax returns for those years as I was employed in several short-term contracts. What should I do?

A. First check the tax computations. The calculation for 2008/09 probably includes the tax due brought forward from 2007/08, so you may only owe £7,200 not £11,700 (£7,200 + £4,500). Next try to find your P60 and P45 forms, and any payslips for those tax years, and check the figures on those forms against the tax calculations. We can help you with this. Don't worry if you haven't retained those papers as the law only requires you to keep then until 31 January 2010, or 31 January 2011 for the later year.

If you had good reason to believe that your tax affairs were in order for 2007/08 you may be able to ask HMRC to write-off the tax underpaid from that year under Extra Statutory Concession A19. You can also ask for the tax for 2008/09 to be collected over 36 months, if it is actually due.

How do I pay tax bills electronically?

Q. I've been told that I will have to pay all my business taxes online very soon. How can I do this if I don't have internet banking?

A. It will be compulsory to pay corporation tax electronically from 1 April 2011, and to pay all VAT due electronically from 2012. However, there are no plans to make all PAYE or CIS payments electronic, yet. Electronic payments include direct debits, debit and credit card payments. You don't have to have internet banking, you can set up electronic payments with your bank by using telephone banking.

If you would rather pay your tax bills by cheque you can do so using a Bank Giro payslip at your own bank branch. This counts as an electronic payment, as do similar payments made at the Post Office counter by cheque, cash or debit card. You need to order the Bank Giro payslips specific to your business from HMRC.

Can I claim entrepreneurs' relief on the whole of the capital distribution paid to me?

Q. In January 2008 I formed C Ltd with my wife, we were both directors and held 50% of the shares each. In March 2010 we split up, her shares were transferred to me and she also resigned as a director. C Ltd ceased trading in July 2010, and it will be wound up informally. Can I claim entrepreneurs' relief on the whole of the capital distribution paid to me on the winding up, or will just part of the distribution qualify because I only held 100% of the shares for the last 4 months that C Ltd traded?

A. You qualify for entrepreneurs' relief on gains arising from all your shares in C Ltd, as you held at least 5% of the ordinary shares for 1 year up to the date the company ceased trading, and you were also a director of C Ltd throughout the last year of trading. Therefore any shares you held in C Ltd qualify for entrepreneurs' relief, and you will pay capital gains tax at 10% on the capital distribution (after deduction of your annual exemption of £10,100), rather than tax at 28% or 18%.

Q. I've just realised I missed £280 of income off my tax return for 2008/09, which I submitted online in January 2010. What should I do?

A. Although this is a relatively small amount you should correct your tax return for 2008/09. However, before you do so double check that you have also included all the expenses and deductions for that tax year, as it looks bad to the Taxman if you correct your return, or 'amend' it in tax-speak, more than once. As you filed your return online you can also amend it online, just log into the self-assessment online area of the HMRC website and pick your 2008/09 return to amend. You have until 31 January 2011 to do this. You may have some more tax to pay for 2008/09 if your extra £280 of income is not covered by losses, allowances or expenses. You should pay the extra tax due as soon as possible as interest will be charged from 31 January 2010.
