Quarterly Tax for UK Landlords — Filed in Minutes
Connect your letting agent, import your transactions, and submit directly to HMRC under Making Tax Digital. No spreadsheets. No accountant required for the filing itself.
The tools your tax return actually needs
Letting Agent Sync
Connect your letting agent via AgentOS and pull rent receipts, maintenance deductions, and management fees directly into your transaction ledger — no manual entry.
Open Banking Integration
Link your bank account via Open Banking and automatically import transactions into your property income records, ready for HMRC categorisation.
HMRC Transaction Categorisation
Map every income and expense line to the correct HMRC property income category. Bulk-categorise across your portfolio or adjust individual transactions inline.
Direct HMRC MTD Connection
Authorise securely via HMRC's OAuth2 flow. Your credentials are encrypted at rest and your connection auto-renews — so submission is always one click away.
Quarterly Submission Dashboard
See all four quarters of the tax year at a glance. Track which are computed, ready, submitted, or accepted by HMRC — with deadline countdowns so nothing slips.
Property Portfolio Management
Add and manage every property in your portfolio. Properties synced from your letting agent come through automatically — with income summaries per property per tax year.
Annual Reports
Generate annual property income statements for your accountant or your own records. Filter by tax year and property, then print or download as PDF.
Encrypted Credential Storage
Your National Insurance Number, HMRC OAuth tokens, and bank credentials are encrypted with AES-256-GCM. No sensitive data is ever stored in plain text.
Audit Trail
Every submission, categorisation, and connection event is logged with timestamps. Full visibility into what was filed, when, and by whom.
From letting agent to HMRC in four steps
Connect your letting agent or bank
Link your AgentOS letting agent account or your bank via Open Banking. Your properties and transactions sync automatically — rent in, maintenance out, management fees noted.
Categorise your transactions
Your imported transactions arrive in the ledger ready to be mapped to HMRC property income categories. Use bulk actions for speed or adjust individual transactions with a single click.
Compute your quarterly summary
Select the quarter and hit Compute. The platform aggregates your income and expenses across your portfolio and presents the figures HMRC expects — with a readiness checklist before you proceed.
Submit directly to HMRC
With your HMRC account connected via OAuth, submit the quarterly return directly through the Making Tax Digital API. Track acceptance status and keep the confirmation on record.
Built around the sensitivity of what you're filing
HMRC-connected. Encrypted end to end. Designed for landlords, not developers.
AES-256-GCM Encryption at Rest
Your National Insurance Number, HMRC OAuth tokens, and bank credentials are encrypted with AES-256-GCM before storage. Domain-isolated keys limit blast radius if any single key is ever compromised.
Direct HMRC OAuth2 Integration
We connect to HMRC using their official OAuth2 Making Tax Digital API — the same mechanism HMRC mandates for compliant software. No screen-scraping, no third-party intermediary.
Full Submission Audit Trail
Every action — categorisation, quarterly submission, HMRC connection, team change — is written to an immutable audit log with timestamps and actor identity.
Role-Based Team Access
Invite your accountant or business partner with controlled access. Owners, admins, and members each have appropriate permissions — no accidental submissions from the wrong person.
