For unincorporated businesses, from 6 April 2024 onwards the cash basis is the default basis of accounts preparation. Unlike the accruals basis under which income and expenditure must be matched to the accounting period to which it relates, where the cash basis is used, income is only taken into account when received and expenditure when paid. This presents some tax planning opportunities around the end of the tax year as regards the timing of income and expenditure.
1. Consider delaying invoicing
If income is likely to be taxed at a higher rate in 2024/25 than in 2025/26, consider delaying invoicing so that a receipt will fall in 2025/26 when it will be taxed at a lower rate.
Example
A sole trader is a higher rate taxpayer in 2024/25, but expects to be a basic rate taxpayer in 2025/26. In March 2025 he undertakes a job, the fee for which is £5,000. If he delays invoicing for the work until April 2025 so that he receives the fee in 2025/26, he will pay tax on it at 20% rather than at 40%.
Delaying invoicing will also delay the time at which the tax is payable on the work. Tax for 2024/25 is due by 31 January 2026, whereas that for 2025/26 is due by 31 January 2027.
2. Consider invoicing early
Conversely, if the taxpayer is a basic rate taxpayer in 2024/25 but expects to be a higher rate taxpayer in 2025/26, or if they have not used their personal allowance for 2024/25, invoicing early so that the receipt falls in 2024/25 rather than 2025/26 will save tax.
3. Consider advancing expenditure
Taxable profits can be reduced by reducing income or increasing expenditure. Where the cash basis is used, taxable profits for 2024/25 can be reduced by bringing forward planned expenditure so that it falls in 2024/25 rather than in 2025/26.
Example
A sole trader is planning to buy a van. The van will cost £15,000. If the van is purchased before the end of the 2024/25 tax year, the expenditure will fall in 2024/25 and can be deducted in calculating the taxable profits for 2024/25, reducing the tax that is payable for that year. If the purchase is delayed beyond 5 April 2025 so that it falls in the 2025/26 tax year, the sole trader will need to wait a further year to benefit from the tax deduction.
4. Consider delaying expenditure
If the taxpayer is likely to pay tax at a higher rate in 2025/26 or has not fully used their 2024/25 personal allowance, it will be advantageous to delay planned expenditure so that it falls within the 2025/26 tax year to secure tax relief for the expenditure at the best possible rate.
