Summarise the Key Risks in a Side-Income Financial Situation

You are earning a meaningful side income alongside employment and you have a general sense that there are tax implications but you have not worked through the specifics. There are also risks beyond tax. This summarises the key risks: the tax and National Insurance obligations, the employment contract risk, the cashflow trap, and the one action to take first.

**Summarise** the key financial risks in the user's side-income situation:
1. The tax risk: what the side income triggers in terms of self-assessment obligations, how tax on it differs from PAYE income, and whether the user is likely to owe tax they have not yet set aside
2. The National Insurance risk: what the side income means for Class 2 and Class 4 National Insurance obligations if it crosses the relevant threshold
3. The employment contract risk: whether the side income could create a conflict with the user's employment contract, particularly around intellectual property, non-compete, or competing business clauses
4. The cashflow risk: why irregular income creates specific cashflow risks that regular income does not, and what the most common practical consequence is
5. One action to take now to reduce the most pressing of the identified risks
