MTD in "untied" - a video walkthrough

This video shows MTD in untied in the browser. As MTD becomes mandated, we'll be adding more functionality and capability to help you stay on top of things.

Also see MTD in the "untied" mobile app.

More detail on the walkthrough

The video covers linking accounts, managing transactions, tagging income and expenses, creating rules, and submitting quarterly and end-of-year updates to HMRC.

Linking your bank accounts

Go to Accounts in the left-hand menu. On smaller screens you may need to expand the menu.

On this page you can view the accounts linked to untied. Live accounts normally appear as connected. You will need to refresh from time to time because bank consent lasts for 90 days.

When you link a new account, transaction history may take a day or two to populate. This is normal. untied validates and processes data in the background.

To add an account, select Add your account, choose your bank, and follow the prompts.

If you hold several accounts with the same bank, link them all in one session. Creating a separate consent can override earlier connections and disconnect accounts already linked.

Viewing and importing transactions

Open the Transactions tab to view your incoming data. A dropdown at the top lets you choose the period displayed. How far back transactions can be imported depends on your bank.

MTD works on the current tax year. Each 6 April, older transactions appear to disappear because the system automatically moves into the new tax year. If you cannot see expected activity, check the tax year filter.

You do not need to link bank accounts to use untied. You can:

Add individual transactions manually
Import a spreadsheet of transactions

Spreadsheet imports allow you to maintain your records externally while using untied as bridging software. Separate help content explains recommended formats.

What HMRC receives under MTD

HMRC do not receive individual transactions. They do not see descriptions, receipts, evidence, or tags.

For most people HMRC only receive totals for income and expense:

Business income
Business expenses
Property income
Property expenses (with interest and finance costs reported separately).

If your income from a single source exceeds £90,000, more detailed categories apply, but HMRC still receive totals only from these more detailed categories.

You must keep digital records consisting of:

A date
A description
An amount

Evidence does not need to be digital. You may store it in untied, in cloud storage, in email, or on paper. You only need to produce it if HMRC request it.

Tagging transactions

Income in foreign currencies is supported. untied converts it to pounds using the correct exchange rate.

The following income types must be reported quarterly under MTD:

Self-employment income
UK property income
Foreign property income

You can tag all other transactions at any time. Items such as donations, interest, or dividends can be tagged during the year or as part of the end-of-year process.

PAYE and pension income are retrieved directly from HMRC and appear automatically.

Filtering and tagging in bulk

Use the search bar to filter transactions.

For example, type “Amazon” to show all Amazon transactions. Select multiple items using the checkboxes and apply a tag to them in one step.

For mixed business and personal transactions, create a partial claim. Enter the business amount, add a note and any evidence, and save. A paperclip icon will appear once evidence is attached.

Creating rules

Rules help automate repeated tagging. To add a rule, open the Rules section on the left.

A rule can:

Identify items based on text (such as “rent”)
Apply a tag automatically
Apply a percentage split for jointly held income
Apply to existing untagged transactions in the current year (or just future transactions)

If applicable, after saving the rule, matching transactions in the current year will update automatically.

You can view your up-to-date tax position at any time by selecting Tax Breakdown. untied automatically applies allowances such as the trading allowance or property allowance where applicable. Rent-a-room relief is shown separately under Tax Forms.

Journeys and other features

Journeys are logged automatically using the untied mobile app. Open Journeys to view, edit, and claim trips. Claims can be applied to business income by default or property income on request.

untied also includes simple invoicing tools and covers other tax areas such as capital gains within Tax Forms.

Setting up Making Tax Digital

When you first open the Making Tax Digital section, untied guides you through linking your account to HMRC and completing the MTD setup.

The central panel shows your MTD obligations. You must submit year-to-date figures four times a year.

untied offers an Auto Submit option, which automatically files your totals after each quarter. This helps prevent missed deadlines. Use Auto Submit if your tagging and rules are up to date. You can also choose to file manually - and you can do this as often as you want.

Filing quarterly or in-year updates

Each income source shows its own set of obligations. Open the dropdown to view due and completed submissions.

To file an update:

Select Submit for the relevant source
Choose whether to file up to the end of the quarter or to today’s date
Submit the figures to HMRC

Filing to today’s date usually provides a more accurate tax calculation. A confirmation email is sent after each submission.

Interest, dividends, gift aid donations, and other adjustments can also be submitted at the same time or later - you'll want HMRC’s records to align with yours. Employment information is brought from HMRC.

Completing the end-of-year tax return

At the end of the tax year, untied guides you through completing the full MTD return. Update each source to ensure figures are correct. You may continue submitting updates until the filing deadline, but you must not miss 31 January.

When ready:

Select Finalise Tax
Confirm your details
Review the calculation
Submit to HMRC

All data is sent through untied. There is no need to log into HMRC separately.
