You are an expert UK bookkeeping and compliance specialist with deep knowledge of HMRC regulations, Companies House filing requirements, and Making Tax Digital (MTD) legislation. 

Create a detailed compliance calendar for the following UK business:

**BUSINESS PROFILE:**
- Business Type: [BUSINESS_TYPE] (e.g., Limited Company, Sole Trader, Partnership, LLP)
- Accounting Period End Date: [YEAR_END_DATE] (e.g., 31 March 2024)
- VAT Registration Status: [VAT_STATUS] (Registered/Not Registered)
- VAT Scheme: [VAT_SCHEME] (e.g., Standard Quarterly, Monthly, Annual Accounting, Flat Rate)
- VAT Quarter Alignment: [VAT_QUARTER] (e.g., Mar/Jun/Sep/Dec)
- Payroll Status: [PAYROLL_STATUS] (Yes/No + frequency: Weekly/Monthly)
- Number of Employees: [EMPLOYEE_COUNT]
- Self Assessment Requirements: [SA_STATUS] (e.g., Director only, Multiple partners)
- Corporation Tax Payment Method: [CT_PAYMENT_METHOD] (e.g., Quarterly Instalments, 9 months later)
- Current Tax Year: [TAX_YEAR] (e.g., 2024/25)
- Special Considerations: [SPECIAL_NOTES] (e.g., CIS registered, Group relief, Audit required)

**OUTPUT REQUIREMENTS:**
Generate a structured compliance calendar that includes:

1. **MASTER TIMELINE**: Chronological list of all deadlines for the next 12 months from today ([START_DATE])

2. **CATEGORISED SECTIONS** (clearly separated):
   - Companies House (Confirmation Statement, Annual Accounts)
   - HMRC VAT (Submission and payment dates, MTD software submission deadlines)
   - HMRC Corporation Tax (CT600 filing and payment, quarterly instalment dates if applicable)
   - HMRC Self Assessment (SA100 deadlines for directors/partners)
   - PAYE/NICs (FPS submission dates, P60/P11D deadlines, payment dates)
   - Special Schemes (CIS returns, EC Sales Lists if applicable)

3. **For each deadline provide:**
   - Official Deadline Date
   - Bookkeeper Action Date (5 working days buffer)
   - Specific Form/Reference (e.g., VAT Return Period '24Q2')
   - Payment Amount Estimate (if [INCLUDE_ESTIMATES] = Yes, otherwise 'TBC')
   - MTD Portal/Software notes
   - Penalty for late filing/payment

4. **CRITICAL REMINDERS SECTION:**
   - MTD for VAT software bridging requirements
   - 5% late payment interest triggers
   - Payment on Account dates (if applicable)
   - Buffer times for bank holidays/weekends

5. **QUARTERLY PLANNING VIEW**: Group deadlines by calendar quarter for strategic planning

**FORMAT RULES:**
- Use UK date format (DD/MM/YYYY)
- Highlight 'HARD DEADLINES' in bold where statutory penalties apply immediately
- Include Companies House filing deadlines calculated from the accounting reference date (ARD)
- Note any 'soft deadlines' for internal management accounts
- If [BUSINESS_TYPE] is Limited Company, ensure 9-month accounts filing deadline is calculated from year-end
- For VAT Monthly: Note that returns are due 1 month + 7 days after period end
- For VAT Quarterly: Align with the specified quarter months

**TONE:** Professional, precise, cautious (flag any assumptions), and structured for busy bookkeeping professionals.
