### Software & Reporting Readiness
- If you're self-employed or a landlord with income over £50,000, research and invest in **digital accounting software** compatible with MTD.
- Start early: practice quarterly submissions in 2025 to avoid last-minute issues.
- Maintain clear digital records—receipts, invoices, statements—to support summaries.
## Sample Compliance Checklist

| Train employees on P9T & code changes | Before April run | HR / Operations |
