Monzo – What You Need to Know

How Monzo Business Handles MTD Compliance

Monzo's MTD tax tool, powered by Sage Embedded Services, supports HMRC-recognised quarterly updates and the final declaration, both submitted directly from within the Monzo app. The product is described as designed for sole traders and landlords, and Monzo's own guidance confirms that qualifying income includes both sole trader and property rental income for threshold purposes. The tool works by leveraging transactions that users have already recorded and categorised in their Monzo account, removing the need to re-enter figures into a separate system.

Monzo allows users to set up separate sub-accounts for different income streams — up to three in total — which can help landlords and sole traders track their income sources distinctly within the same account. The tool includes clear in-app explainers, a tax timeline, quarterly deadline reminders, and the ability for an accountant to carry out MTD obligations on the user's behalf. Monzo does not provide detailed confirmation that its tool covers foreign property income specifically.

Monzo Business: No Property Management Features

Monzo Business has no property portfolio management, tenant management, rent tracking, compliance document alerts, or HMO-specific features. These are banking and tax tools, not landlord management tools. Landlords using Monzo as their MTD solution must manage all property administration — tenancy agreements, rent collection, maintenance tracking, compliance certificates — entirely outside the app. There is no joint ownership splitting capability; landlords with jointly owned properties would need to manage their individual share of income and expenses manually within their own Monzo account.

Monzo Business: In-Bank Transaction Recording

Monzo's digital record keeping is inherently banking-based: all transactions through the Monzo account are automatically captured and stored digitally, satisfying the MTD requirement to hold digital records. Users categorise transactions as they arrive in the app. However, Monzo does not offer a chart of accounts, journal entries, double-entry bookkeeping, or formal accounting reports. It connects to external accounting software (Xero, QuickBooks, FreeAgent, Sage) on Pro and Team plans, which is how users access more structured bookkeeping and reporting. The accounting depth sits in those third-party tools, not in Monzo itself. Monzo explicitly operates in GBP only — there is no multi-currency support.

Monzo Business: In-App Categorisation, Receipts, and Tax Pot

Monzo's expense management is simple and effective for most sole traders: transactions are categorised as they arrive in the app, receipts can be attached to any transaction, and VAT details can be added. Invoicing — including customisable invoices with payment links and QR codes — is available on Pro and Team plans (from £9/month). A standout feature is the Tax Pot: on Pro and Team plans, Monzo automatically transfers a user-defined percentage of every payment received into a dedicated pot reserved for tax. This prevents under-saving for tax throughout the year and is a genuine, practical advantage that RentalBux does not currently match.

Monzo Business: Spending Insights and Cash Flow Dashboard

Monzo provides Insights — a real-time dashboard showing income, expenses, and a monthly cash flow report. This gives sole traders and landlords a live view of their business financial position based on transactions flowing through the account. However, Monzo does not produce formal accounting reports such as P&L statements, balance sheets, or trial balances within the app itself — these require connection to an external accounting tool like Xero. There is no dedicated tax forecasting feature, though the Tax Pot functions as a practical tax-saving proxy.

Monzo Business: Team Plan and In-App Banking

The Monzo Team plan (£25/month) provides multi-user access for up to 15 team members in a limited company (or up to 3 for a sole trader), expense cards with individual spending limits, bulk payments, and payment approval workflows. Each team member can see their own spending while the account owner retains full visibility. Pro and Team plans allow accountants to be connected via accounting software integrations (Xero, FreeAgent, Sage, QuickBooks). There is no dedicated accountant portal within Monzo itself, but the accounting integrations provide real-time data access for advisors. Monzo's MTD tool supports agent filing, allowing accountants to submit quarterly updates on behalf of their clients.

Monzo Business: Ease of Use and Support

Monzo is widely regarded as one of the UK's most user-friendly banking apps — intuitive, mobile-first, and designed for people who are not accountants. Its MTD tool follows the same design philosophy: simple, tap-based flows for categorising transactions, attaching receipts, and submitting quarterly updates. Monzo offers 24/7 in-app support and telephone support, and has maintained a strong reputation for customer service as one of the UK's most recommended business banking providers.
