# Getting Monzo transactions into your books Canonical: https://taxmo.co.uk/monzo-bank-feed-uk Last updated: 2026-08-10 Two routes, and it is worth knowing which you need. Upload a CSV statement and Taxmo recognises the Monzo layout without you mapping a single column, or connect the account through Open Banking for the current period. Either way the transactions land in the same review queue, and the same records go on to produce the VAT return that Taxmo files to HMRC. ## The Monzo layout, recognised on sight Taxmo detects a Monzo statement from its own column names rather than asking you to map fields. For Monzo that means the Name column for the merchant, falling back to Description, and a single signed Amount column, so money out is negative and refunds are positive, with day-first dates. If your export has extra columns, they are ignored rather than getting in the way. ## What actually goes wrong with a Monzo export None of these are reasons not to import. They are the things worth knowing before you assume a number is right. - Monzo applies its own categories to your spending. They are useful for personal budgeting and they are not HMRC expense categories, so Taxmo categorises from your own rules rather than importing Monzo's labels - Pot transfers appear as transactions. Moving money between your own pots is not income or expense, and those rows should be excluded at review rather than approved - The merchant name in the Name column is usually cleaner than the raw reference, which makes Monzo one of the easier statements to set categorisation rules against ## Open Banking, and its one real limit You can connect the account instead of exporting a file. The connection is read-only account information, authorised by you at Monzo's own sign-in rather than by giving Taxmo any credentials. The limit to know about: it is an on-demand import rather than a background sync, so you re-authorise each time you pull transactions and each pull returns a recent window instead of your whole history. For older periods, the CSV route has no such window. ## Then the records do the rest Transactions arrive pending and are not in your figures until you approve them, with categorisation rules you set once applied on the way in. Once approved they feed your running tax estimate, your profit and loss, and the nine boxes of your VAT return, which Taxmo submits to HMRC directly over the Making Tax Digital API. Importing Monzo activity is the first step in that chain rather than an end in itself. ## Business and personal in one account Plenty of sole traders run business and personal spending through the same account, and there is nothing wrong with it as long as the books separate the two. Personal spending is not an allowable cost and must not reach your expense figures. Import everything so nothing is missed, then exclude the personal rows at review, which is faster and safer than trying to filter the export by hand. ## Common questions ### Can I import Monzo transactions into Taxmo? Yes, two ways. Export a CSV statement and upload it, and the Monzo layout is detected automatically with no column mapping. Or connect the account through Open Banking, which is read-only and authorised at Monzo rather than by handing over credentials. CSV is the route for older periods, because the connection returns a recent window rather than your full history. ### Does the Monzo connection sync automatically? No, and we would rather say so plainly. The UK Open Banking connection is on-demand: you re-authorise at your bank for each import. You never get a feed that quietly stopped working when a consent lapsed, but you do trigger the import yourself. ### Does Taxmo import my Monzo categories? No, and it should not. Monzo's categories are built for personal budgeting and do not map onto HMRC expense categories, so importing them would produce confident labels that are wrong for tax. Taxmo categorises from rules you set, which then apply automatically to future imports. ### Do I have to categorise every Monzo transaction by hand? Only the first time. Rules you set are applied to incoming transactions, so a supplier you have categorised once is categorised on every future import. What reaches you for review is the ambiguous remainder rather than the whole statement. ### Can I file my VAT return from imported Monzo transactions? Yes, once they are approved. Approved transactions feed the nine boxes, and Taxmo submits the return to HMRC directly over the Making Tax Digital API with HMRC's receipt stored against the period. Transactions still sitting unapproved are excluded from your figures, which is why the pre-filing checklist blocks on them. ### Do I still need to keep receipts? Yes. A bank line proves money moved, not what it bought or how much VAT it carried, and for a VAT reclaim the VAT invoice is the evidence rather than the bank row. Import the statement so nothing is missed, keep the receipts so the figures are defensible. ## Related pages - [Import a CSV statement from any UK bank](https://taxmo.co.uk/import-bank-transactions-csv) - [Getting Starling transactions into your books](https://taxmo.co.uk/starling-bank-feed-uk) - [Submit your VAT return to HMRC, from your own records](https://taxmo.co.uk/submit-vat-return-to-hmrc) --- This page explains how UK rules work rather than quoting thresholds, rates or allowances, which are indexed or reset at fiscal events.
