MTD for Landlords With Multiple Properties: Complete Guide

If You Own Multiple Rentals, MTD Just Got More Complex

Making Tax Digital for Income Tax (MTD for ITSA) is coming. If your gross rental income — across all your properties combined — exceeds £50,000, you must comply from 6 April 2026. If it's over £30,000, April 2027 is your date. Over £20,000? April 2028.

For landlords with one property, this is fairly straightforward. But if you own two, five, or fifteen properties, there are specific record-keeping requirements that catch people out. This guide covers exactly what you need to track, how software handles it, and which tools work best for property portfolios.

What MTD Actually Requires From Landlords

Under MTD for ITSA, you must submit a quarterly update to HMRC for each source of income. For landlords, that typically means one submission covering your entire UK property business — you don't file per property, but your records need to show per-property income and expenses clearly.

You'll submit four quarterly updates per tax year, then a final end-of-period statement (EOPS) and a final declaration (which replaces the traditional Self Assessment return).

The Record-Keeping Minimum

For each property, you must record:

• Rental income received — dates and amounts, per property
• Allowable expenses — maintenance, letting agent fees, insurance, mortgage interest (restricted to 20% tax credit), repairs, and so on
• Property details — address, whether it's furnished, residential or commercial
• Mileage and travel costs if you visit to manage or maintain properties

HMRC doesn't require you to upload receipts digitally, but you must keep digital records that your MTD-compatible software can read and use to generate your submissions. Paper records alone won't cut it from your MTD start date.

The Multiple-Property Challenge

This is where landlords with portfolios hit a wall with basic bookkeeping tools. Most simple accounting software is built around one income stream. When you have several rentals, you need software that can:

• Track income and expenses per property
• Consolidate everything into a single UK property business figure for HMRC
• Handle shared expenses (like insurance covering multiple properties)
• Manage multiple tenants per property if you rent by the room
• Report on individual property profitability so you know which ones are pulling their weight

Not all MTD-compatible software does this well. Some treat your entire property portfolio as one bucket. That works for compliance but tells you nothing useful about your portfolio.

Which Software Works Best for Multiple Properties?

Here's an honest breakdown of how the main options handle property portfolios. You can compare MTD software side by side to see current pricing and features.

FreeAgent

FreeAgent has solid landlord functionality, letting you set up multiple properties and track income and expenses against each one. It handles the MTD quarterly submissions automatically and produces clear reports per property. The interface is clean and genuinely beginner-friendly. Currently 50% off for the first six months.

QuickBooks Self-Employed / QuickBooks Sole Trader

QuickBooks is strong on bank feeds and receipt capture — useful if your property expenses are spread across multiple accounts. You can categorise transactions per property with some setup. The bank reconciliation is excellent. Currently running a 90% off deal for seven months, making it the cheapest entry point right now.

Xero

Xero is the most powerful option for landlords with larger portfolios. Its tracking categories feature lets you assign every transaction to a specific property, giving you granular reporting. If you have ten or more properties and want real financial visibility, Xero earns its higher price tag. Currently 95% off for six months (expires 31 March — act fast).

Sage Accounting

Sage is a reliable, well-established option. It handles MTD submissions competently and is comfortable for landlords used to more traditional accounting tools. Solid rather than flashy. Currently 90% off for ten months.

GoSimpleTax

GoSimpleTax is built specifically for the UK self-assessment market, including landlords. It's simpler than the others but very focused on getting your tax return done correctly. Good if you want something no-frills that handles property income without the business accounting overhead.

Furnished Holiday Lettings: A Special Case

If any of your properties qualify as Furnished Holiday Lettings (FHLs), be aware that from April 2025, the special FHL tax regime was abolished. FHL income is now treated the same as other residential property income. Your MTD software doesn't need to treat these differently, but it's worth knowing your previous FHL advantages — like full mortgage interest relief — no longer apply.

Setting Up Your Records Before April 2026

Don't wait until your MTD start date to sort this out. Getting your records in order now means your first quarterly submission in summer 2026 won't be a scramble.

Here's a practical setup process:

• Open a dedicated bank account for your property business if you haven't already. This makes bank feed reconciliation in your software dramatically simpler.
• List every property with its address and whether it's residential, commercial, or HMO. You'll need to set these up in your software.
• Categorise your expense types — maintenance, letting agent fees, insurance, mortgage interest, utilities you cover, ground rent, service charges. Map these to the HMRC categories your software uses.
• Start digital record-keeping now — photograph receipts with your phone and upload them. Getting into the habit early removes the stress later.
• Decide on cash or accruals basis — most landlords use the cash basis (you record income when received, expenses when paid). Check with your accountant if you're unsure which applies to you.

Joint Ownership and Partnerships

If you own properties jointly with a spouse or partner, each of you has your own MTD obligation based on your share of the income. Most MTD software handles the individual filing — you each need your own software subscription and HMRC sign-up. Your records need to show clearly what percentage of each property's income and expenses belongs to you.

If you own properties through a limited company, MTD for ITSA doesn't apply — that's handled through Corporation Tax, which has a separate digitalisation timeline.

What Happens If You Miss a Quarterly Submission?

HMRC is introducing a new points-based penalty system alongside MTD. Each missed submission earns a penalty point. Rack up enough points and you receive a financial penalty. The system is designed to be lenient with occasional mistakes but firm with persistent non-compliance.

The key is that quarterly updates are cumulative — you're not doing a new tax return every three months, just updating HMRC with your running totals. Good software makes this a ten-minute job, not a half-day exercise.

The Bottom Line for Landlords

MTD for ITSA is not optional, and it's not far away. If your rental income across all properties exceeds £50,000 gross, you have less than a year to get set up. If you're in the £30,000–£50,000 band, April 2027 sounds distant but isn't.

The landlords who'll find this easiest are the ones who pick the right software now, set up per-property tracking from day one, and build digital record-keeping into their monthly routine before the deadlines hit.

Take ten minutes to compare MTD software and find the option that fits your portfolio size and budget. Several providers are running significant discounts right now — there's a real financial incentive to get started today rather than waiting.
