	2018/19	2017/18
Entry threshold – turnover up to:	£150,000	£150,000
Exit threshold – turnover not more than:	300,000	300,000

Entry threshold is £300,000 for Universal Credit claimants.
Unincorporated trading businesses with annual turnover within the above limits can choose to calculate taxable profits on the ‘cash basis’ – income received and expenditure paid, rather than invoiced or accrued.
Deduction for loan interest is limited to £500 per year.
Losses can only be carried forward.
Certain businesses are not permitted to use the cash basis, including: farmers using the herd basis, persons using profit averaging, and LLPs.
Unincorporated property businesses can use the cash basis from 6 April 2017. The key differences to the rules for trading businesses are:
- the entry and exit thresholds are both £150,000;
- cash basis is the default position for such businesses, but they can elect to use accrual accounting;
- there is no £500 restriction on interest costs
