Frequently asked questions
How do I connect my HMRC account?
+
Navigate to Settings → HMRC Connection and click 'Connect to HMRC'. You'll be redirected to Government Gateway to authorise Regulas. Once authorised, your businesses will sync automatically.
What happens if my quarterly submission fails?
+
Regulas will display the specific HMRC error message. Common causes include missing obligation periods or invalid data. Fix the flagged fields and resubmit — your data is never lost.
Can I use Regulas alongside my existing accounting software?
+
Yes. Regulas is specifically designed for Making Tax Digital compliance. Many users continue using their preferred bookkeeping tools for day-to-day records and use Regulas for HMRC submissions.
Is my data backed up?
+
All data is stored in AWS-managed PostgreSQL with automated daily backups. Your digital records are retained for the HMRC-required minimum of 5 years plus the current tax year.
What if HMRC APIs are down?
+
Regulas monitors HMRC service status. If APIs are unavailable, you'll see a status banner in the app. All local features (bookkeeping, categorisation, reports) continue to work offline from HMRC.
How do I cancel my subscription?
+
Go to Settings → Subscription → Cancel. Your data will be retained for 90 days after cancellation. You can export all digital records at any time before or after cancelling.
