Once you become self-employed, the tax rules are quite different from those that may have applied when you were an employee. Instead of tax and national insurance being deducted from your earnings at source, you must be prepared to receive a bill at some time in the future.

This can be an unwelcome surprise if you haven't put enough money aside. We aim to give you as much warning as possible of the likely timing and amount of tax payments, but it is not easy to do this during the first year of your new business, or if you do not keep your records up-to-date.

The starting point for the calculation of taxable profits is your profit and loss account. In calculating taxable profits you are entitled to claim deductions from your business income in respect of any expenses incurred for the purposes of the trade with a few minor exceptions.

When you buy equipment or motor vehicles, you will be entitled to deduct a proportion of the cost each year you own them and use them in your business. Claims for such capital expenditure are known as capital allowances. If you take stock for your own use, the disposal should be shown in the accounts at market value , and not at original cost.

It may be possible to avoid this by arguing that such items never actually formed part of your stock and showing the original purchase as private expenditure drawings.

Tax is payable on the whole of the profits of a trade, and so payments for your own 'wages' drawings are not deductible.

However, if your spouse works in the business, the wages can be an allowable deduction, provided they are actually paid, the payment is based on a commercial rate, and the details are reported to HMRC. The aim of the system is that over the lifetime of your business, the profits will be taxed in full once and once only. But to make the system fair, there are certain complications you will have to cope with. The general rule is that the tax for a particular tax year is based on the profits of the 12 months to your accounting date in that tax year.
