Procentowo rozliczasz jeśli wydałeś więcej niż 100tys - 2011/2012
A jeśli mniej to wszytko wrzucasz w Annual Investment Allowance
You can claim a capital allowance called an Annual Investment Allowance (AIA), if you bought equipment (but not cars) during the year up to an annual amount of £100,000. Add the cost of all the equipment together and, if the total cost is £100,000 or less, you can claim 100 per cent of that whole amount as your AIA. If the total is more than £100,000, then you can claim up to £100,000 of the total as your AIA.
w tym roku 2012/2013 w taki sposób będzie można odliczyć tylko 25tys.
(The annual amount of AIA will be reduced to £25,000 for expenditure incurred on or after 6 April 2012).
