Reduce errors
HMRC's policy is that more structured digital records should help reduce avoidable mistakes in tax reporting.
Tax compliance, with less uncertainty.
Making Tax Digital, made simpler.
Solomon Sage is building a technology-enabled tax compliance service for UK landlords and sole traders. We review the records you maintain, help resolve issues and process the quarterly updates required under Making Tax Digital for Income Tax.
Why Solomon Sage exists
Tax reporting is becoming a year-round responsibility.
For many landlords and sole traders, tax has traditionally been something dealt with mainly once a year. Making Tax Digital changes that rhythm.
Digital records, compatible software and quarterly reporting are becoming part of the normal tax cycle. Solomon Sage exists to make that transition clearer and easier to manage.
Our aim is simple: combine useful technology with professional oversight so that you spend less time worrying about compliance and have more confidence that the right things are being done at the right time.
MTD explained
What is Making Tax Digital for Income Tax?
Making Tax Digital for Income Tax is HMRC's digital reporting regime for individuals with qualifying self-employment and property income.
Instead of dealing with business income and expenses mainly through one annual Self Assessment process, taxpayers within MTD must keep qualifying records digitally and send information to HMRC during the year using compatible software.
Quarterly updates are not four full tax returns.
They are summary updates generated from your digital records.
Encourage digital records
The regime moves qualifying businesses and landlords towards digital record keeping and compatible software.
More current information
Reporting during the year is intended to give taxpayers and HMRC a more up-to-date view of business information.
Who is affected
MTD is being introduced in stages.
The first phase is already live. The threshold is based on combined gross qualifying income before expenses from property and self-employment.
April 2026
Over £50,000
First mandatory phase.
April 2027
Over £30,000
Threshold reduces.
April 2028
Over £20,000
Current final planned phase.
Some taxpayers may qualify for an exemption, including in certain cases of digital exclusion. Eligibility depends on the detailed HMRC rules and individual circumstances.
What you need to do
Four core MTD responsibilities.
The practical change is less about a new tax calculation and more about how records are kept and information is reported during the year.
Keep digital records
Maintain the required income and expense information digitally rather than relying solely on paper records.
Use compatible software
Your digital records and submissions must work through software that can meet HMRC's MTD requirements.
Send quarterly updates
Provide HMRC with summary income and expense information during the tax year.
Complete the year-end process
Finalise the year's tax position, including the relevant adjustments and annual filing requirements.
Quarterly deadlines
7 August
7 November
7 February
7 May
The normal annual finalisation deadline is 31 January following the end of the tax year.

Frequently asked questions
The practical questions people ask first.
Does MTD for Income Tax apply to landlords?
Yes, it can. Individuals with qualifying property income can fall within MTD once their combined gross qualifying income from property and self-employment exceeds the relevant threshold.
How do I know if I am over the threshold?
The threshold is based on gross qualifying income before expenses from qualifying property and self-employment activities combined. It is not based on profit or the number of properties you own.
Do I have to submit four full tax returns?
No. Quarterly updates are summary updates generated from your digital records. The year-end process remains separate.
Do I need special software?
You need compatible software capable of meeting HMRC's MTD requirements. Solomon Sage's service is being designed around a defined digital process so that customers do not need to work this out alone.
What are the quarterly deadlines?
The standard quarterly update deadlines are 7 August, 7 November, 7 February and 7 May.
What happens if I miss a deadline?
MTD uses a points-based late-submission penalty system. Repeated missed obligations can result in financial penalties, while separate rules apply to late payment of tax.
Will Solomon Sage maintain all my bookkeeping records?
Not under the initial service model. You maintain your underlying records. Solomon Sage reviews and processes those records for the quarterly MTD reporting cycle.
Can I use Solomon Sage if I already have an accountant?
Possibly. The right arrangement will depend on what your existing adviser already handles and where responsibility for MTD sits. We want the process to be clear rather than duplicated.
