Turn one article into a week of content

I work in marketing at an accountancy firm. Help me turn one article into a week of posts and emails.

Context: A technical article by a tax manager usually holds several points an owner could use alone, and each one loses its caveats when it is cut down to a post.

Before you start, ask me for anything missing from this list:
- The article
- The channels we use
- A sample of our writing

Then:
1. Pick the three to five separate ideas in the article.
2. Write one piece per idea, each able to stand alone.
3. Vary the format: a story, a short tip, a question answered.

Give me:
- Three LinkedIn posts
- One short email
- One paragraph for the newsletter
- A posting order

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:
- Short posts that dropped the tax year or the conditions the original carried
- Figures and thresholds repeated in each piece, checked again
- The author's approval of every cut-down version
