MTD ITSA for landlords is the requirement to keep digital records of rental income and allowable expenses, then submit quarterly updates to HMRC through compatible software. It applies to UK landlords whose 2024/25 gross rental income (combined with any self-employment turnover) exceeded £50,000. The regime went live on 6 April 2026 and the first quarterly submission falls due on 7 August 2026.
What counts as a landlord under MTD ITSA?
HMRC's definition is broader than most people assume. Anyone receiving income from UK property is in scope: residential buy-to-let landlords, holiday let owners, owners of furnished rooms beyond the Rent-a-Room limit, commercial landlords, and even people letting a single room in their main home if the income falls outside Rent-a-Room relief. What matters is the £50,000 qualifying income test, calculated on gross rents (before agent fees, mortgage interest, repairs) plus any other self-employment income.
So a landlord with two properties grossing £30,000 and a small consultancy turning over £25,000 is in MTD ITSA from April 2026. A landlord with a single property grossing £18,000 and no other self-employed income is not — they'd join when the threshold drops to £30,000 in April 2027 only if income rises, or to £20,000 in April 2028.
Why landlords have it harder than sole traders
The basic regime is identical, but property reporting introduces complications that pure sole traders sidestep. Three big ones: jointly-owned property, the finance cost restriction, and the difference between repairs and improvements. Each has been a source of HMRC enquiries for years and MTD doesn't simplify any of them — it just makes them quarterly.
Jointly-owned property: each owner submits separately
This catches a lot of couples off-guard. If you and your spouse jointly own a buy-to-let, you each submit your own MTD ITSA quarterly updates for your share of the income. There's no joint return. Default split is 50/50 unless you've filed a Form 17 to declare a different beneficial split. The £50,000 threshold is also assessed individually — so if a jointly-owned property generates £80,000 gross with a 50/50 split, each spouse has £40,000 of qualifying property income and neither is automatically in MTD from April 2026 (though either may be from April 2027 when the threshold drops to £30,000).
| Ownership | How it's reported under MTD |
|---|---|
| Sole ownership | One quarterly update, full income and expenses |
| Joint owners (default 50/50) | Each owner submits their share separately |
| Joint owners with Form 17 | Each submits their declared beneficial share |
| Property in a partnership | Partnership submits MTD updates from April 2027 onwards (separate regime) |
| Property in a limited company | Not in MTD ITSA — Corporation Tax regime applies |
If you've been treating jointly-owned rental income as a single line on one spouse's Self Assessment for years, MTD forces a clean-up. Both partners need their own software access — though FreeAgent and Xero allow multi-user accounts for a small additional fee, and many accountants are setting up shared workspaces to handle this efficiently.
The finance cost restriction: still here, still annoying
Mortgage interest on residential lets hasn't been fully deductible since 2020. You get a 20% tax credit on finance costs instead of treating them as an expense — a rule that hammered higher-rate landlords and pushed many into limited companies. That hasn't changed under MTD. What has changed is how it's reported quarterly: finance costs go into a separate line on your quarterly update ("residential property finance costs"), and the 20% credit is calculated automatically by your software at year-end.
For most accidental landlords with a single mortgaged property, this means the headline gross rent on your quarterly update will look healthy, but the actual taxable profit (after mortgage interest is restricted to a credit) will be lower. Don't panic when Q1 figures come back showing big numbers. Year-end maths fixes it.
Repairs vs improvements: the categorisation HMRC checks
Repairs are an allowable expense. Improvements are capital expenditure, not deductible against income, only against capital gains tax when you sell. The line between them is blurry and HMRC enquiries hammer this regularly. A like-for-like boiler replacement is a repair. Upgrading from gas to a heat pump is arguably an improvement. New double-glazing replacing old single-glazing has historically been treated as a repair on the basis that single-glazing is no longer commercially available — but expect HMRC's stance to harden as energy efficiency improvements get reframed as capital.
Under MTD, you categorise these decisions four times a year instead of once. Most landlord software platforms handle this with a tick-box at transaction entry: "Is this a repair or an improvement?" Get it wrong consistently and you're asking for a compliance review.
Categories landlords use most
| Category | What goes in |
|---|---|
| Total rents and other income | Rent received, balancing payments, recoveries from tenants |
| Premises running costs | Council tax (where you pay it), water rates, ground rent, service charges |
| Repairs and maintenance | Boiler servicing, decoration, minor repairs, gas safety certificates |
| Property management fees | Letting agent commissions, management fees, tenant find fees |
| Legal & professional | Conveyancing on lease renewals, accountant fees, eviction costs |
| Insurance | Buildings, contents (for furnished lets), landlord liability |
| Residential finance costs (separate) | Mortgage interest — gets 20% tax credit, not deduction |
| Other allowable | Travel to property, advertising vacancies, void utilities |

Quarterly cadence for landlords
Same cadence as sole traders, but submitted as a separate property update — not merged with self-employment income. If you're both a sole trader and a landlord, you'll have two quarterly updates per quarter (eight per year), submitted from the same software login but as distinct items.
- Q1: 6 April – 5 July 2026, due 7 August 2026.
- Q2: 6 July – 5 October 2026, due 7 November 2026.
- Q3: 6 October 2026 – 5 January 2027, due 7 February 2027.
- Q4: 6 January – 5 April 2027, due 7 May 2027.
- Final Declaration for 2026/27: 31 January 2028.
Software that actually fits landlords
The major generalist platforms (FreeAgent, Xero, QuickBooks) handle property income, but landlord-specific tools tend to do it better. Hammock, Landlord Vision, and Provestor are built around the rental workflow — tenancy tracking, rent due reminders, gas safety reminders, deposit protection logging. Pricing sits in the £15-£35/month range, which is more than QuickBooks Sole Trader but cheaper than hiring an agent for record-keeping. For landlords with three or more properties the specialist tools usually pay for themselves in saved admin alone. For one or two properties, FreeAgent at £19/month (or free with NatWest) is fine.
Our software comparison covers the generalists in detail; specialist landlord tools are worth a separate look if you're managing a portfolio.
The £1,000 property allowance — still useful
The property allowance lets landlords with gross rental income under £1,000 a year ignore the income entirely for tax purposes. Useful for the occasional Airbnb-er, irrelevant for anyone in MTD ITSA scope. The allowance doesn't disappear under MTD — it just doesn't help you, because by definition you're well above the £50,000 qualifying income threshold.
What about furnished holiday lets?
The Furnished Holiday Lettings regime ends 6 April 2026 — same date MTD ITSA starts. Holiday let income now falls under standard property income rules: no more capital allowances on furniture, no more pension-eligible earnings status, finance cost restriction applies. From an MTD perspective, holiday let income goes into the standard property quarterly update alongside long-term rentals. The categorisation is identical; only the underlying tax treatment changed.
Mistakes landlords are already making three weeks in
Patterns from the first three weeks of the regime:
- Submitting joint property income on one spouse's account. If you've been doing this for years on Self Assessment, MTD won't accept it. Each owner needs their own login.
- Treating mortgage interest as a regular expense. Software flags this if you categorise it as "finance costs" properly, but if you mis-tag it as a generic admin expense the year-end maths will be wrong and the tax credit lost.
- Forgetting deposit returns aren't taxable income. When a tenant moves out and you return their deposit, the bank feed shows an outflow that looks like an expense — it isn't, it's just returning money you held in trust. Tag as a deposit refund, not as an expense.
- Missing voids in expense categorisation. When a property is empty between tenants, the council tax and utilities you pay are still allowable. Software sometimes auto-categorises these as personal because there's no rent coming in. Override.
Capital gains tax: separate, still annual
Selling a rental property triggers CGT, reportable through the dedicated 60-day CGT-on-property-disposal service, not through MTD ITSA. The two regimes don't talk to each other. Don't expect your MTD software to file your CGT return when you sell — that's a separate manual job.
If you're a landlord still on the fence
The realistic cost of compliance for a small landlord (1-3 properties, no self-employment) is £180-£250/year for software plus maybe four hours a quarter of admin. That's marginal in the context of typical rental yields. The bigger cost is psychological — being forced to look at your portfolio's numbers four times a year instead of avoiding them until January. Most landlords find the discipline useful after a few quarters. A few decide it's the final straw and exit the buy-to-let market entirely. Both reactions are rational; pick the one that fits your life.
