Prepare for the Jan 2026 mandate by securely connecting KinderStart to HMRC.
From April 2026, the way childminders report income to HMRC is changing. "Making Tax Digital" (MTD) replaces the annual Self-Assessment with four quarterly updates. KinderStart is designed to handle this transition seamlessly, acting as your official "functional compatible software".
Mandatory enrolment begins in April 2026 for those with a total business and property income over £50,000. If your income is between £30,000 and £50,000, you join in April 2027.

MTD Timeline
Before linking KinderStart, notify HMRC that you are moving to MTD for Income Tax.
Once you have your credentials, create the "Digital Link" required by law.
KinderStart becomes MTD-ready once you complete setup. The connection takes under a minute.
OAuth 2.0 Security. KinderStart uses the official HMRC secure authorisation flow. You will be briefly redirected to the GOV.UK website to sign in and grant KinderStart permission to send your records. We never see or store your Government Gateway password.
The MTD screen includes a roadmap to ensure you are fully compliant before the mandate hits:
Review your record-keeping practices now. Any gap in your digital trail becomes a gap in your quarterly submission.
KinderStart stores your digital records securely and keeps them for the full 6-year HMRC retention period.
The 6-Year Rule. HMRC requires you to keep digital records of all transactions for at least 6 years. Upload your receipts to KinderStart to fulfil this requirement. Even if you lose the paper copy, your digital record is legally valid.
