Build an FAQ page

I work in marketing at an accountancy firm. Help me build an FAQ page from the questions we get asked.

Context: Most questions start with 'do I need to' or 'how much', and the honest answer often depends on income, business structure and the tax year in question.

Before you start, ask me for anything missing from this list:
- Questions clients ask, in their words
- Our answers, even as rough notes
- The service the page supports

Then:
1. Group the questions by what the person is trying to decide.
2. Rewrite each question the way a client would type it.
3. Answer each in 40 to 80 words with the answer in the first sentence.
4. Mark any answer that depends on the person's circumstances.

Give me:
- Grouped questions and answers
- A list of answers that need a specialist to confirm

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Give general information only. Never write anything that reads as tax advice on a person's own affairs, and never suggest a tax saving or an outcome with HMRC is likely or guaranteed.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else the partner who approves marketing or our ethics and compliance lead should see:
- Answers that could be relied on as advice on someone's own tax position
- Rates, thresholds and filing dates quoted in answers, with the tax year
- Fees quoted in answers, against the current price list
