Do I Need MTD Software Now?

If your gross rent is over GBP 50,000 a year from April 2026, MTD is no longer theory for you, it is your new filing system. Ignoring it just swaps one annual tax chore for quarterly panic plus penalties.

"This guide provides general information about UK landlord tax obligations. It is not financial or legal advice. Tax treatment depends on your individual circumstances and may change. Consider consulting a qualified accountant or solicitor for advice specific to your situation."

1. Are you actually in scope yet?

MTD for Income Tax (MTD ITSA) phases for sole-trader landlords:

• From 6 April 2026 - if your qualifying gross income (property + sole-trade) is GBP 50,000+ based on your 2024-25 tax return.
• From 6 April 2027 - if your qualifying gross income is GBP 30,000+ (2025-26 return).
• From 6 April 2028 - if your qualifying gross income is GBP 20,000+ (2026-27 return).

"Qualifying gross income" means:

• Total rent before any expenses (your share only) from all properties, plus
• Any self-employed turnover,
• Ignoring PAYE salary, pensions, dividends and interest.

So if you have:

• GBP 28,000 gross rent + GBP 24,000 sole-trade turnover = GBP 52,000 = in at 2026.
• GBP 22,000 gross rent, nothing else = in at 2028.

2. What you must do if you are in scope

If your 2024-25 return shows GBP 50,000+ of qualifying income:

From 6 April 2026 you will:

• Keep digital records of all rental and business income and expenses.
• Use MTD-compatible software to send:
• 4 quarterly updates to HMRC, and
• A single Final Declaration instead of the old SA100.

What to do now if you are over GBP 50k

1. Confirm your qualifying income from your last return (or your accountant's workings).
2. Choose MTD-compatible software that handles:

• Multiple properties,
• Bank feeds,
• Digital record-keeping and quarterly submissions.

1. Start keeping digital records from 6 April 2026 (earlier if you want a dry run).
2. Use the MTD guide (2.5) plus your accountant to set up categories and workflows.

If you are below 50k but above 30k or 20k based on your current trajectory, you have roughly 1-2 extra years but should still pick software and move off spreadsheets now. The direction of travel is clear.

3. What happens if you ignore MTD?

HMRC is moving to a points-based penalty system for late MTD submissions:

• Every missed quarterly update earns 1 penalty point.
• Reach 4 points and you get a fixed financial penalty (exact amount set in regulations, on top of any interest).
• Points can expire after a period of compliance, but repeat offenders keep paying.

Late payment penalties sit on top of this, based on how long tax remains unpaid.

HMRC has trailed a soft landing for 2026-27 quarterly updates (focusing on education rather than automatic fines), but:

• Late Final Declarations and late tax payments will still be penalised from day one.

So "I will wait and see" really means:

• Scrambling when you pass GBP 50k.
• Missing early deadlines while you learn the software.
• Burning your points for avoidable errors.

4. Practical next step by income band

Already at GBP 50k+ gross (or close)

• Treat MTD as live now.
• This quarter: pick software, run parallel records with your current system, and book time with your accountant to set up categories.

GBP 30-50k gross

• You are likely in from April 2027.
• Use the next 12 months to:
• Move your bookkeeping to MTD-ready software.
• Clean up your property records so each property's income and costs are clearly separated.

GBP 20-30k gross

• You are likely in from April 2028 if income holds up.
• Use MTD guide (2.5) and the MTD readiness tool to sense-check whether growth (rent increases, extra properties) might pull you into the earlier bands.

The key is to decide now whether you will:

• Self-manage in software, or
• Offload bookkeeping and MTD submissions to an accountant or specialist.
