Small business owners should make plans now to take advantage or minimise the pain of a raft of new accounting rules that will come into force in April.

According to accountancy firm and business advice company PKF, entrepreneurs should act now to ensure they are not caught out by any of the changes, despite the fact that there is a Budget on 12th March and that a finance bill is also expected to be introduced before the end of that month.

"This Spring is probably the most important ever in terms of getting your tax affairs in order and arranging your finances to save tax," said Lisa Macpherson, national director of tax at PKF.

"This is a very busy year because many changes to long-established tax rules take effect from 6 April 2008.

"There are many planning opportunities available in the run up the end of the tax year but it will pay to get things moving now, even if you have to wait until after the Budget before completing the arrangements."

PKF recommends small business owners should focus on the following areas:

This Spring is probably the most important ever in terms of getting your tax affairs in order and arranging your finances to save tax

Non-doms
Non-doms should review their overseas arrangements now as individuals who are UK-resident but non-domiciled face substantial changes to the tax treatment of their foreign income and gains from 6th April 2008. Some of these may bring income and gains arising in past years within the UK tax net

Check your visits
Individuals visiting the UK for short periods should check their visiting pattern carefully. HMRC has been tightening up on its approach to visits and new rules from 6th April will mean that days of arrival and departure must be counted

Private investors
Making the most of the changes in the capital gains tax rules that take effect from 6th April could mean selling assets now, transferring them to a spouse or delaying a sale until the new tax year. What is most tax-efficient for each investor will depend on your investments and circumstances, so starting the number-crunching as early as possible is vital

Trusts
Major changes to the way trusts are taxed were announced in 2006 but the transitional period, during which settlors and trustees can change current arrangements to ensure they remain tax-efficient, ends on 5th April

Pre-Budget IHT
As the Government has made a major concession by introducing the transferable nil-rate band in the Pre-Budget Report, it is highly likely that it will ‘take with the other hand' in the Budget. Individuals considering plans to reduce their family's inheritance tax bill should try to put them in place before the Budget on the 12th March to make sure that current tax reliefs can be used

Transfer of income-producing assets
Spouses and civil partners can save tax by transferring income-producing assets between them to ensure that tax allowances and rate bands are used effectively. With the government taking increasing interest in family tax planning (see income of business owners above), it may be wise to make any relevant transfers of assets before the Budget

Pension contributions
The option to make large personal pension contributions is particularly important this year as with the reduction in the basic rate of income tax from 6th April 2008 onwards amounts going into your fund will only be topped up with a 20% tax credit, rather than the 22% addition to contributions the government currently makes

Capital gains of business owners
Most business owners are aware that the 10% effective rate of tax on gains from selling your business will rise to 18% on 6th April unless the gain is under £1m and they meet the tests for the new entrepreneurs relief. However, not all will realise that there are a number of ways to ‘bank' the 10% rate by making a disposal even if you cannot at present sell your business outright

Income of family company owners
Those owning their own family company will have to consider the new ‘income shifting rules' where other family members work in the business or receive dividends. If your business is likely to be affected, extracting profits by way of dividends before 6th April is your last chance to allocate the profits around the family tax-efficiently

Business investment
Business owners considering purchasing new plant or machinery should assess whether advancing or delaying expenditure will earn them faster tax relief as many changes to the capital allowances regime take effect from April (1st April for companies, 6th April for unincorporated businesses)
