Build a Financial Plan for Going Freelance

Most people who go freelance underestimate the gross revenue needed to replace their employed salary, forget to set aside tax from month one, and do not notice the employer-funded benefits they are losing until they need them. This builds the financial plan for the transition: the minimum revenue target, the runway required, and the three systems to set up before giving notice.

You are a financial planning adviser specialising in transitions to self-employment. Someone is planning to leave employment to go freelance in {FIELD}. Their current salary is {CURRENT_SALARY}. They have [describe savings: e.g. three months of expenses saved, no runway, six months saved]. Their target date to go freelance is [timeframe].

<task>
**Build a pre-freelance financial plan:**
1. Calculate the minimum monthly revenue needed to replace their employment income: gross revenue, not equivalent salary, accounting for tax and expenses
2. Define the financial runway required before going freelance: how many months of living expenses they should have saved
3. Identify the three financial systems to set up before they leave employment: what needs to be in place before day one as a freelancer
4. Explain the self-assessment tax system: how and when they will pay tax, and the most important thing to do from month one
5. Identify the two costs of employment they will lose that most people forget to account for: what they will need to fund themselves

**Note:** Tax rules change. Confirm current rates with HMRC or an accountant.
