KEYPrime (Landmark) – What You Need to Know

How KEYPrime (Landmark) Handles MTD for Landlords

MTD for Income Tax Self Assessment was introduced into the KEYPrime Accounts range in version 14.5 (released December 2025). Users access it via the HMRC menu in Ledgers within KEYPrime Accounts. The process requires: setting up taxable business entities (entering National Insurance number and linking to HMRC via Government Gateway); mapping each income and expenditure nominal in the chart of accounts to the appropriate Self Assessment category; reviewing transactions allocated to each taxable entity; and then submitting the four quarterly obligations and the Final Declaration for each taxable entity.

Landmark's own update notes confirm the system handles both quarterly submissions and a Final Declaration per taxable entity, with the category allocation based on the nominal mappings. KEYPrime Accounts is confirmed by Landmark as HMRC-approved for Making Tax Digital for Income Tax. MTD for VAT has been supported since 2019, when Landmark facilitated digital VAT submissions for over 7,000 companies using the KEYPrime range.

KEYPrime Property: Estate and Agricultural Property Management

KEYPrime Property is designed for a far wider range of property types than any residential landlord platform. It manages residential properties, commercial sites, agricultural tenancies, containers, caravan parks, shooting rights, and more. Core features include tenant and tenancy management, automated rent demand generation, multi-tenancy service charge management (including bulk updates), metered utility recharging for tenants (via the Metering module), compliance date reminders for critical deadlines, document attachment across the system, and detailed financial and property reports for landlords and tenants. It also includes a Client Accounting module for agents managing multiple landlord clients within a single system.

KEYPrime Accounts: Full Double-Entry Accounting for Rural Businesses

KEYPrime Accounts (Intro, Accounts, and Advanced) is a comprehensive double-entry bookkeeping system designed for rural businesses of all sizes. It supports both cash basis and accruals basis accounting, a fully customisable chart of accounts, journal entries, fixed asset register with depreciation, foreign currency transactions, full VAT management (standard, cash, and flat rate), and a wide range of financial and management reports. The Advanced tier adds Sales Order Processing (SOP), Purchase Order Processing (POP), stock management, and enterprise-level analysis and budgeting. A Consolidator module allows multi-company reporting — essential for estate structures with multiple legal entities.

KEYPrime: Automated Rent Demands, Service Charges and Document-Driven Entry

KEYPrime Property automates rent demand generation from configured tenancy schedules. Invoices are customisable with business logos via template layouts. Service charges can be processed for multiple tenancies simultaneously. The Metering module generates utility recharge invoices automatically from meter readings. For expense capture, KEYPrime integrates with Dext (formerly Receipt Bank) and AutoEntry — users can photograph invoices and receipts which are then imported into KEYPrime Accounts. This integration-based approach works well for accounting practices but requires a separate Dext/AutoEntry subscription.

KEYPrime: Comprehensive Business and Property Reporting

KEYPrime Accounts and KEYPrime Property together produce an extensive reporting suite. Financial reports include profit & loss, balance sheet, trial balance, VAT reports, debtor and creditor ageing reports, and enterprise-level analysis. Property-specific reports include rent books, demands reports, tenancy reports, arrears analysis, and client statements for agents. The Consolidator module enables multi-company consolidated reporting for complex estate structures. Enterprise budgeting allows "what if" analysis. Advanced tier adds cashflow reports and detailed enterprise margin reporting.

KEYPrime's Collaborative Features

KEYPrime is available as a Windows PC installation or as a web-hosted solution. PC installation offers offline working capability — valuable for rural estate offices with unreliable connectivity. The web-hosted option enables remote access from office and tablet devices. There is no dedicated native iOS or Android mobile app, though the web-hosted version can be accessed via mobile browsers. Accountant and consultant licences are available, allowing professionals to access client data to assist with final accounts and analysis. The KEYPrime Accounts system supports HMRC agent feeds, allowing the accountant to authorise submissions on behalf of clients.

KEYPrime's Ease of Use

KEYPrime is a professional accounting system designed for users with bookkeeping knowledge. The AccountingWEB community notes that it requires understanding of debits and credits to operate effectively, and initial setup — particularly chart of accounts mapping and MTD nominal configuration — benefits from consultant or accountant support. However, once configured correctly, users report significant time savings on routine tasks such as rent demand generation.
