Obtain receipts for everything.
Tax payers lose millions each year by not obtaining or retaining receipts for expenses. If you are claiming fuel costs for a business trip and fill up with £50 of petrol get a receipt. The tax saved by including that receipt in your accounts is £11 at basic tax rates and £20 at higher tax rates. If your business turnover is over the vat threshold of £64,000 p.a. for 2007-08 the receipt is worth even more. £16.81 vat and income tax at basic tax rate and £24.47 at the higher income tax rate. The same is true for all other business receipts. Obtain a receipt for everything. If you lose a receipt then still include that expenditure in your accounting records but if your tax return is enquired into by the Inland Revenue that expenditure may be disallowed unless you can argue and sometimes prove the expense was in fact incurred. May help to note in your records – receipt lost.
Do not mix business and personal.
The general rule is that items solely for business use can be claimed for tax purposes and the business proportion of personal expenditure may be allowed although the rules are applied quite strictly. If you purchase both business and personal items from a supplier the business expenses only can be claimed but if you obtained all the items on a single receipt you would be disallowed the cost of that journey as it was not solely for business purposes.
Claim business expenses incurred prior to trading.
Business expenses incurred up to seven years prior to trading actually commencing can be deducted from business turnover if these expenses were solely for the future business purposes. Enter such expenses in your accounting records as if they had been incurred on the first day of trading but show the actual purchase date.
Claim home costs if you work from home.
If part of your home is identifiable as solely for business purposes then home costs can be claimed. The cost allowed is the proportion of the total area of the home the business area occupies. For example, excluding shared facilities of kitchen and toilet if the home has three bedrooms, living and dining room and one bedroom is used solely as an office then 1/5 of home costs could be claimed. The home costs to claim would be heat and light, insurance, general and water rates and mortgage interest excluding repayment amounts. Where mortgage interest is claimed the revenue might also claim as a capital gain the increase in value of that proportion of the home, such Capital Gains Tax being subject to tapering relief over time. It may be safer not to claim mortgage interest as part of the home costs.
