About Quarter Day Books

For centuries, England's rents fell due on four quarter days: Lady Day, Midsummer, Michaelmas and Christmas. Making Tax Digital has brought the quarter back. Landlords now report to HMRC four times a year.

Quarter Day Books makes plain, well-built spreadsheets and guides that turn that into a short, calm job. We're independent and not affiliated with or endorsed by HMRC.

How we write and check our guides

• Every rule, date and threshold is checked against GOV.UK, and each page links to its sources.
• Each page shows when it was last checked. We re-check them at least every quarter and whenever HMRC changes its guidance.
• We use AI tools to help research, draft and build our guides and products. Everything is checked against official sources before it's published.
• Our guides are general information, not tax advice. For advice on your own situation, speak to a qualified accountant.
