Property Accounts and MTD Quarterly Updates: Managing Both

Two Systems, One Set of Records

If you rent out property and you're now filing quarterly updates under Making Tax Digital, you've probably noticed something awkward. Your letting agent sends a monthly statement. Your mortgage lender uses a different reference period. HMRC wants your figures in four specific date windows. And somewhere in the middle, you're supposed to maintain a "Property Account" that makes sense of all of it.

This guide is for landlords who are trying to keep their property records in order while also hitting MTD quarterly update deadlines - starting with the 7 August 2026 deadline for Q1. It explains what each system actually needs from you, where the records overlap, and how to build one simple filing habit that covers both without duplicating the work.

What Is a Property Account and Why Does It Matter?

A Property Account is not a formal HMRC product. It is the set of records you keep to show your rental income and expenses for each property across a tax year. HMRC expects landlords to hold this information regardless of MTD - it is a basic record-keeping requirement that predates Making Tax Digital by decades.

Your Property Account should show:

• Rent received from each tenant, by date
• Void periods where no rent was received
• Expenses paid for each property - repairs, insurance, agent fees, mortgage interest, and so on
• Any deposits received and held
• Capital improvements that are not immediately deductible

This is the record HMRC can ask to see if they open an enquiry into your rental income. It is also the source data you draw on when completing your MTD quarterly updates and your end-of-year tax return.

For more on what HMRC expects you to keep, see our post on HMRC record-keeping standards for MTD compliance.

What MTD Quarterly Updates Actually Require

MTD quarterly updates are not full accounts. They are a summary of your income and expenses for a specific three-month window. For the 2026-27 tax year, the four quarters are:

1. 6 April to 5 July - deadline 7 August 2026
2. 6 July to 5 October - deadline 7 November 2026
3. 6 October to 5 January - deadline 7 February 2027
4. 6 January to 5 April - deadline 7 May 2027

For each quarter, you submit totals for your property income categories. HMRC does not need receipts at this stage, but the figures you submit must be based on accurate underlying records. If they are not, you will face problems at the end of year when you reconcile everything in your final declaration.

See our first MTD Q1 filing guide for landlords for a full breakdown of what property income categories to include.

Where the Two Systems Overlap

The good news is that these two systems need largely the same underlying data. The difference is in how they use it.

Your Property Account records rent received, expenses paid, and any other relevant transactions as they happen throughout the year. Your MTD quarterly update takes a snapshot of those records every three months and sends a summary to HMRC.

In other words:

• Property Account - the ongoing, detailed record of everything, kept throughout the year
• MTD quarterly update - a periodic summary drawn from those records, filed four times a year

If your Property Account is up to date and organised by quarter, completing each quarterly update takes very little time. If it is not, you end up scrambling before each deadline - and that is where most landlord errors happen.

The Problem Most Landlords Are Running Into

On forums like PropertyTribes, the confusion tends to follow a pattern. Landlords are not sure whether they need to keep separate records for MTD or whether their existing spreadsheet or letting agent statements are enough. Some worry they are duplicating work. Others have not reconciled their records at all and are filing quarterly updates based on rough estimates.

None of these approaches is sustainable. Filing inaccurate quarterly updates creates problems at final declaration. And if HMRC opens an enquiry - which is more likely once quarterly data is being received - a disorganised Property Account is difficult to defend.

See our post on preparing records after your Q1 MTD filing for more on what HMRC may ask to see.

A Simple System That Covers Both

You do not need two separate systems. You need one well-organised record-keeping habit with MTD deadlines built into it. Here is a practical approach that works for most landlords.

Step 1 - Set Up One Record Per Property

Whether you use a spreadsheet, accounting software, or a simple folder system, keep a separate record for each property. Each record should have columns or sections for:

• Date of transaction
• Type of income or expense
• Amount received or paid
• Which MTD quarter it falls into
• Supporting document reference (invoice number, bank statement line, etc.)

If you have multiple properties, a simple spreadsheet with one tab per property and a summary tab works well. Bridging software like AffordableMTD can import from a spreadsheet directly, which means your Property Account and your MTD filing process are the same document.

Step 2 - Update Records Monthly, Not Quarterly

The biggest mistake landlords make is leaving their records until just before the quarterly deadline. Updating monthly takes ten to twenty minutes and means your records are always current. It also means you catch errors - missing rent payments, duplicate expense entries, or agent fees that were charged incorrectly - before they compound.

A simple monthly habit:

1. Download your bank statement for the month
2. Match each rental credit to your property record
3. Add any expenses paid - repairs, insurance premiums, agent invoices
4. File the receipt or invoice digitally (a photo on your phone is enough)
5. Check that the quarterly total is tracking sensibly

Step 3 - Reconcile at Quarter End Before Filing

At the end of each quarter - so around early July for Q1 - take thirty minutes to reconcile your records before submitting. This means checking that:

• The total income in your Property Account for the quarter matches what went into your bank account
• Every expense has a corresponding receipt or invoice
• You have not accidentally included a capital expense as a deductible repair
• Agent management fees and any one-off letting fees are categorised correctly

Our June Q1 reconciliation guide walks through this process in detail for the first quarter.

Step 4 - File the Quarterly Update From Your Reconciled Records

Once you are confident your records are correct, filing the quarterly update itself should take no more than a few minutes. You are simply entering the totals you have already calculated.

If you use AffordableMTD, you can import your figures from a CSV or enter them directly. The software handles the submission to HMRC's API, so there is no manual XML or API work on your part.

Letting Agent Statements and MTD Periods

A common complication for landlords who use letting agents is that agent statements usually run calendar month to calendar month. MTD quarters run from the 6th of the month. This creates a small mismatch that you need to account for.

The practical approach is to use your bank account as the primary record rather than agent statements. Record the date that rent actually landed in your account. That date determines which MTD quarter the income falls into.

Agent fees work the same way - record when they were actually deducted or paid, not when the statement was dated.

If your agent pays rent in arrears (which many do), there may also be some months where income from one calendar period arrives in the following quarter. Keeping bank records as your primary source avoids confusion here.

Multiple Properties: Keeping It Manageable

If you have two or more properties, the same system applies - but the volume of transactions is higher. A few things that help:

• Keep a separate bank account for rental income if possible. This makes reconciliation much faster.
• Use a separate spreadsheet tab or folder for each property, not one combined sheet.
• Label every receipt with the property address it relates to. A repair receipt for the wrong property creates an error that is surprisingly hard to untangle at year end.

For landlords who also have self-employment income, there is an additional layer of complexity - your self-employment records need to be kept separately from your property records, and both feed into the same MTD filing. Our guide on mixed income and MTD for landlords with self-employment covers this in more detail.

What to Keep and for How Long

Under MTD, you are required to keep digital records of your income and expenses. This does not mean every receipt needs to be in a specific software - a photo saved to a folder with a logical naming system is sufficient for most purposes.

HMRC expects you to keep property records for at least five years after the 31 January submission deadline following the relevant tax year. For 2026-27, that means until at least 31 January 2033.

What to keep:

• Bank statements showing rent received
• Letting agent monthly statements and annual summaries
• Receipts or invoices for every expense claimed
• Mortgage statements showing interest paid (if you are still claiming finance cost relief)
• Insurance schedules and renewal notices
• Any correspondence about repairs or works done
• Tenancy agreements for the periods covered

See our post on HMRC rental income enquiries and the records you need for a fuller list.

Common Mistakes and How to Avoid Them

Mixing capital and revenue expenses

A new bathroom is a capital improvement. Replacing a broken toilet seat is a repair. Only the repair is deductible against rental income in the year it is paid. Getting this wrong is one of the most common Property Account errors - and it shows up quickly when HMRC reviews your quarterly update totals over time.

Forgetting void period costs

Expenses incurred during a void period - such as insurance, council tax, or repairs - are still deductible. Many landlords forget to include these because there is no corresponding income entry for that period. Keep a note in your records when a property is void and make sure any costs paid during that time are still logged.

Claiming the wrong finance costs

If you have a buy-to-let mortgage, you cannot deduct the full mortgage payment as an expense. You are restricted to a tax credit on the interest portion only, and even that is handled differently from straightforward expense deductions. Make sure your Property Account records the interest element separately.

Submitting before reconciling

As mentioned above - file after you have checked, not before. Our Q1 final checks guide gives you a pre-submission checklist to work through.

After Q1 - Building the Habit for the Rest of the Year

Once you have filed your Q1 update by 7 August, the next quarterly deadline is 7 November for Q2. That covers 6 July to 5 October - meaning Q2 records have already started accumulating.

The landlords who find MTD manageable are those who treat it as a quarterly rhythm rather than four separate panics. If you update your Property Account monthly and reconcile at quarter end, the filing itself takes very little time.

For what to do immediately after Q1, see our post on what to do once your August update is submitted.

Summary

Property Accounts and MTD quarterly updates are not two competing systems - they are two uses of the same underlying records. If you keep accurate, up-to-date records of your rental income and expenses throughout the year, the quarterly update becomes a ten-minute task rather than a stressful deadline. The key is to update monthly, reconcile before you file, and treat the 7 August Q1 deadline as a prompt to get your whole system in order - not just a one-off admin job. Get the records right, and everything else follows from that.
