Spreadsheet vs MTD software for landlords

TenancyVault availability: Bookkeeping and bank import are included from Solo. HMRC connection and direct filing workflows are subject to production approval and release; public direct filing is not yet available. Product filing steps below describe the intended workflow, not a currently available public submission service. Check current scope before relying on software for a deadline.

Many landlords use spreadsheets for rental records. MTD can accommodate them with compatible bridging software and digital links. This guide compares that approach with integrated software; neither approach removes the need to review records and check supported filing functions.

The core problem with spreadsheets under MTD

HMRC’s MTD requirement has two parts:

1. Keep digital records
2. Submit quarterly updates through software that connects to HMRC

A standalone spreadsheet does not submit to HMRC. It can form part of your digital records, but needs compatible software to complete reporting and digital links to move information between the relevant software components.

This means spreadsheet-only landlords face a choice:

• Add bridging software that connects the spreadsheet to HMRC
• Switch to purpose-built MTD software

Option 1: Spreadsheet + bridging software

Bridging software connects spreadsheet records to HMRC. Use supported digital transfers, such as linked cells or CSV import/export; do not manually re-key or copy and paste totals between the components. Check support for cumulative updates and the tax return, not just an advertised HMRC connection.

Potential advantages:

• You can keep your existing spreadsheet layout
• May be lower cost than full MTD software

Disadvantages:

• Two separate tools to maintain
• You maintain the spreadsheet formulas and categories
• Error risk at the point of data transfer between tools
• No property-level organisation unless you build it yourself
• Does not reduce the bookkeeping work

Option 2: Purpose-built MTD software

Software designed for MTD keeps your records and files directly to HMRC — there is no separate bridging step.

Capabilities to compare, rather than assume:

Spreadsheet	MTD software
No HMRC connection	Direct HMRC connection
Formulas can calculate totals	Check cumulative year-to-date totals
Imports depend on spreadsheet tools	Check supported bank import formats
Categories and transfers need review	Check categorisation and correction controls
Protect formulas and retain versions	Check change history and export options
Correct records and digitally link to bridging software	Check next-update and post-fourth-update corrections
HMRC workflow depends on bridging software	Check supported status and filing functions

What landlord-focused software adds

Generic bookkeeping software (designed for businesses generally) often requires setup work to represent rental property structures correctly. Landlord-focused software is organised around properties and tenancies from the outset.

TenancyVault’s available bookkeeping and import features from Solo let you:

• Assign each record to a specific property
• Review income and expense records by property
• Import bank statements and assign categories during review
• Keep personal transfers separate without building custom logic

Public HMRC connection and filing remain subject to approval and release. Do not interpret bookkeeping availability as a live submission service. For corrections, follow the cumulative-update process, not an assumption that every earlier quarter must be amended separately.

Common reasons landlords keep using spreadsheets too long

• Familiarity — they have used the same spreadsheet for years and it feels easier
• Cost — spreadsheet software is already paid for
• Assuming filing can wait: establish your start date and supported software before an update is due

Leave time to test transfers, reconcile totals and confirm authorisation before a deadline. Migration requirements depend on your records and software; a change does not automatically require importing years of history.

How to decide

Compare supported income sources, digital links, correction workflows, annual filing, exports and cost. Integrated software can reduce transfers between tools, while bridging can retain a suitable existing spreadsheet.

If you have a complex or bespoke spreadsheet and do not want to rebuild it, bridging software is a legitimate option — but you need to factor in the continued maintenance cost of both tools.
