Making Tax Digital Compliance

How Capium Handles MTD Compliance

Capium's MTD for Income Tax solution operates at two levels. At the practice level, accountants use Capium's MTD module and practice management suite to manage all client MTD quarterly submissions, track deadlines, review submission status, and handle final declarations. At the client level, Capium 365 provides the bookkeeping and record-keeping interface through which landlords and sole traders capture receipts, connect bank feeds, and categorise income and expenses.

Capium's official MTD IT page explicitly states that self-employment, UK property, and foreign income reports are automatically populated from live digital records for MTD quarterly updates and final declarations. AccountingWEB confirmed that Capium 365 allows accountants to configure income stream categorisation so clients can clearly distinguish between UK and foreign sources, or between property and self-employment income. Capium has confirmed live pilot completions for both UK Property income and Self-Employment tax returns through the HMRC MTD pilot.

Property Management

Capium: No Property Management Features

Capium does not include property portfolio management, tenant management, rent tracking, compliance document reminders, HMO support, or any landlord-specific property administration tools. It is an accountancy practice management platform. Property management is entirely outside Capium's scope and must be handled separately by the landlord or via other specialist tools.

Bookkeeping, Accounting & Digital Record Keeping

Capium 365: Cloud Bookkeeping for Sole Traders and Landlords (Practice-Delivered)

Capium 365 is a cloud-based bookkeeping solution that provides the client-facing record keeping for MTD IT. It includes unlimited bank feeds (free with a Capium 365 licence), automated bank reconciliation, automated transaction categorisation with supplier rules, and the ability to upload up to 50 invoices and receipts at once. Income streams can be configured by the accountant to clearly separate UK property, foreign property, and self-employment income. P&L reports are available for limited company clients within Capium 365. For landlords with more complex accounting needs, all Capium 365 data feeds directly into the practice's Capium suite for self-assessment, accounts production, and year-end work.

Invoicing, Expense Tracking

Capium 365: Bulk Receipt Upload with Accountant-Driven Document Requests

Capium 365 allows clients to scan and upload up to 50 invoices and receipts at once through the mobile app or web platform. Supplier rules and automation handle transaction categorisation. A distinctive feature is Capium's bulk document request tool: accountants can send batched requests to multiple clients simultaneously, asking for specific receipts or documents, and then track which clients have submitted and which have not — significantly reducing the time spent chasing clients ahead of quarterly MTD submissions.

Reporting & Tax Forecasting

Capium: Practice-Wide Dashboards and Statutory Reporting

Capium's practice dashboard gives accountants full submission status visibility across all MTD IT clients — tracking which quarterly updates have been submitted, which are pending, and which are overdue. Capium's Accounts Production module produces full statutory accounts (full, abbreviated, or abridged year-end accounts) submitted directly to Companies House. The Self Assessment module produces all SA forms. Real-time data flows between modules so information entered once in bookkeeping or Capium 365 auto-populates into SA, CT, and AP.

Collaboration & Mobile Apps

Capium's Collaborative Features

Capium is accountant focused. The accountant is the primary user, and the landlord (as a client) accesses Capium 365 as a data capture and record-keeping layer that feeds directly into the accountant's compliance workflow. For practices managing large numbers of landlord and sole trader clients under MTD, Capium's collaboration infrastructure — unlimited users, client portal, bulk document requests, multi-client submission dashboard, and 6-day-a-week support — is genuinely best-in-class.

Unique Features Only Capium Offers

Full-Suite Practice Accountancy Platform in One Integrated System

Capium uniquely integrates Accounts Production, Corporation Tax, Self Assessment, Payroll, Practice Management, Company Secretarial, AML, MTD for VAT, MTD for Income Tax, and bookkeeping in a single cloud platform — with data flowing between modules automatically. This eliminates the need for multiple separate software products and is the core value proposition for UK accounting practices.

MTD for VAT (9-Box Submissions with Spreadsheet Bridging)

Capium supports MTD for VAT with automated 9-box calculations and spreadsheet bridging alongside its MTD IT offering.

Accounts Production — Statutory Accounts to Companies House

Capium's Accounts Production module produces full, abbreviated, and abridged year-end accounts and files them directly to Companies House — recognised by both HMRC and Companies House. This is an accountancy practice tool with no equivalent in a landlord platform.

Self Assessment (SA100, SA800, SA900, SA109)

Capium's Self Assessment module automatically pulls through financial data for all SA forms and submits directly to HMRC, supporting sole traders, partnerships, trusts, and landlords. All form types and client categories are covered.

Payroll with Auto-Enrolment and RTI Submissions

Capium's Payroll module handles payroll calculations, auto-enrolment, and Real Time Information (RTI) submissions — covering the full payroll compliance cycle for employment-based clients.

Anti-Money Laundering (AML) — KYC, Risk Assessments, Sanctions and PEP Checks

Capium's AML module provides Know Your Customer checks, risk assessments, and third-party client verification including sanctions and PEP (Politically Exposed Persons) screening — essential compliance tooling for accountancy practices under UK AML regulations.

Bulk Document Requests with Client Submission Tracking

Accountants using Capium 365 can send batched document requests to multiple clients simultaneously and track which have responded. This is a material efficiency gain for practices managing large volumes of MTD IT client work.

Multi-Client MTD Submission Dashboard

Capium's practice-side dashboard gives accountants full visibility of MTD IT submission status across all clients — showing quarterly update status, outstanding obligations, and deadline positions in one view.

Capium 365 — Client-Facing Bookkeeping with Unlimited Bank Feeds and Document Storage

Capium 365 provides clients with unlimited bank feeds (free with licence), unlimited user access at no additional cost, unlimited document storage, and full integration with the practice suite — a comprehensive client collaboration tool that feeds directly into the accountant's compliance workflow.
