What bookkeeping records do I legally have to keep?

You need enough to prepare a correct return and to prove the figures if HMRC asks: all sales and other income, all business expenses, bank and cash records, and — if you are VAT registered — a VAT account. If you hold stock, you need year-end stock figures. If you own business assets, you need records of what you bought, when, and for how much. The test HMRC applies is whether the records support the return, so a bank statement alone is rarely enough: it shows £340 left your account but not what it was for or whether it was allowable. That is why the receipt matters as much as the payment. Under MTD these same records simply have to be kept digitally rather than in a folder.

How long do I need to keep my records?

Sole traders and landlords must keep records for at least five years after the 31 January submission deadline for the relevant tax year, which in practice means nearly six years from the end of the tax year itself. Limited companies must keep theirs for six years from the end of the accounting period. VAT records must be kept for six years. If a return was filed late, or HMRC has opened an enquiry, the clock runs longer — keep everything until the enquiry is settled. Digital records make this considerably easier, since the retention obligation is discharged by the software rather than by a loft full of boxes. Do not assume your bank fills the gap: most banks only make a few years of statements available, and the duty is yours, not theirs.

Do I have to keep paper receipts if I photograph them?

No — a clear digital image is an acceptable record, and you can throw the paper away once it is captured, with one significant exception. HMRC accepts scanned or photographed documents provided the image is legible and shows all the information the original did. The exception is anything showing VAT paid that you intend to reclaim on an unusual footing, and any document you might need in original form for a non-tax reason, such as a warranty or a legal dispute. The practical failure mode is not legality but legibility: a blurred, half-cropped photo of a faded till receipt is not a record, it is a picture of one. Most software has a phone app that captures, reads and files the receipt against the bank transaction in one step.

Can I use my personal bank account for my business?

Legally yes if you are a sole trader or landlord, but it is the single most expensive habit we see. Nothing prohibits it — you and the business are the same legal person — but every transaction then has to be sorted by hand rather than flowing in through a bank feed, which is precisely the manual work MTD is designed to remove. It also weakens you under enquiry, because HMRC can ask to see the whole account and you lose the clean line between business and private spending. For a limited company it is different and more serious: the company's money is not yours, and paying personal costs from the company account creates director's loan and benefit-in-kind problems. A separate account costs little and pays for itself immediately.

How do I handle cash takings?

Record them at the point they arise, every day, and bank them intact rather than spending out of the till. Cash is where most enquiries start, because it is the only income with no automatic trail — a bank feed proves a card payment happened, but nothing outside your own records proves a £20 note did. So the discipline is a daily takings record, reconciled to what you bank, with any cash spending recorded separately rather than netted off. Under MTD the takings record must be digital, though you can record a day's takings as a single daily total rather than every individual sale. What you cannot do is work backwards from your bankings at year end. That is not bookkeeping, and it does not survive contact with an inspector.

What is the difference between cash basis and accruals accounting?

Cash basis counts income when the money arrives and expenses when they leave; accruals counts them when the work is done or the cost is incurred, regardless of payment. Cash basis is now the default for most sole traders and partnerships, and you have to elect out to use accruals. For a trade paid promptly, cash basis is simpler and gives a fairer picture. Where it hurts is if you carry significant unpaid invoices, hold stock, or have large equipment purchases, because the timing distortions can be substantial and some reliefs work differently. Limited companies must use accruals; there is no choice. This is a decision worth making deliberately rather than by default, and it is one of the first things we look at when taking someone on.

My books are years behind — can you catch me up?

Yes, and it is a routine job rather than a confession. Catch-up work starts with whatever exists — bank statements, an app full of receipts, a carrier bag — and rebuilds each year in sequence, because you cannot do the recent ones without the opening position from the older ones. Where records are genuinely missing we reconstruct from bank data and reasonable estimates, and where an estimate is unavoidable we disclose it rather than presenting a guess as fact. If returns are late, the priority is usually to file rather than to perfect, because late filing penalties accrue while you polish. HMRC treats an unprompted disclosure very differently from one that follows their letter, so the time to start is before they write, not after.

Should I do my own bookkeeping or outsource it?

Do it yourself if your affairs are simple and you will genuinely keep up; outsource if the honest answer to that is no. Modern software has narrowed this considerably — with a bank feed and receipt capture, a sole trader's bookkeeping is often twenty minutes a week of approving suggestions, and paying someone to do that is poor value. The calculation changes when you have staff, stock, CIS, multiple income streams, or a track record of leaving it until it is a crisis. The hidden cost of self-managed books is not the time, it is the year-end: if your categories are wrong, we spend our fee unpicking them, and you pay for both. Many of our clients land on a middle position where they do the routine and we review each quarter.

How do I split costs that are part business and part personal?

Claim the business proportion, and be able to explain how you arrived at it. A phone used 70% for work means 70% of the bill is allowable; a van used privately at weekends needs a mileage-based restriction. The method matters less than the evidence: a defensible basis you applied consistently will survive scrutiny, while a round 50% you cannot justify will not. Working from home follows the same logic, though there is a flat rate available that avoids the calculation entirely and is usually the right answer for modest use. What HMRC objects to is not apportionment but the absence of any reasoning behind it. Record the basis when you set the split, not two years later when you are being asked to remember it.

What does bookkeeping look like once MTD applies to me?

Broadly the same work, done continuously rather than in one annual panic. The obligations do not change — the same records, the same evidence — but they must be kept digitally and, because you are summarising to HMRC every quarter, they have to be reasonably current rather than reconstructed in January. That is the real behavioural shift, and it is the one that helps most: problems surface within weeks instead of ten months later when the counterparty has vanished. In practice, for a client on software with a bank feed, it looks like approving categorised transactions weekly and photographing receipts as you get them. The annual shoebox becomes impossible, which people mourn briefly and then stop missing.

Bookkeeping for Self‑Employed Landlords: A Calm, Practical System That Keeps You Compliant

In this guide: Overview Benefits Process FAQs

Bookkeeping for landlords doesn’t need to be complicated — but it does need to be consistent. If you’re self-employed and earn rental income, good records are what turn a stressful January scramble into a straightforward set of figures you can stand behind.

In this guide, I’ll walk you through what to keep, how to organise it, and a simple routine that works whether you have one buy-to-let or a small portfolio. I’ll also explain what’s changing with Making Tax Digital (MTD) and why it’s worth getting your bookkeeping “MTD-ready” now.

What does “bookkeeping” mean for a self-employed landlord?

For landlords, bookkeeping is simply keeping a clear record of:

Rental income (what you charged and what you actually received)
Allowable property expenses (costs you can claim against rental income)
Key documents (invoices, receipts, statements, tenancy agreements, agent statements)
Important dates (repairs, safety certificates, renewals, void periods)

In practice, the goal is to be able to answer these questions at any time:

How much rental income have I received this tax year?
What have I spent, and what was it for?
What can I legitimately claim?
What evidence do I have if HMRC ever asks?

Why landlord bookkeeping matters (even if your tax bill feels “small”)

Bookkeeping is not just a box-ticking exercise. It helps you:

Pay the right tax (not too much, not too little)
Reduce mistakes that can trigger HMRC queries
Stay on top of cash flow (especially around mortgage payments, repairs and voids)
Make better decisions about rent increases, refurbishments, or whether a property is still performing

And with MTD for Income Tax coming in, good bookkeeping will move from “helpful” to “essential”.

MTD for landlords: what’s changing and why you should care now

Making Tax Digital for Income Tax (often called MTD ITSA) is bringing in digital record-keeping and more frequent reporting for many landlords.

If you want the full landlord-specific picture, this guide explains the rollout and what HMRC will expect: Making Tax Digital for Landlords (MTD ITSA): What UK Property Owners Need to Know for 2026–2028.

The key practical point is this: instead of pulling everything together once a year for Self Assessment, many landlords will need to keep digital records and send quarterly updates to HMRC using compatible software.

What records should landlords keep?

A good landlord bookkeeping file (digital or paper-backed-up-by-digital) usually includes:

1) Income records

Rent received (date, amount, property)
Any other property income (for example, laundry, parking, or service charges you recharge)
Letting agent statements (these are very useful for reconciling what you should have received vs what you did receive)

2) Expense records (with evidence)

Repairs and maintenance invoices/receipts
Safety certificates and compliance costs (e.g. gas safety checks)
Insurance documents
Letting agent fees
Accountancy fees related to the property business
Replacement of domestic items (where relevant)

3) Bank and card statements

Even if you keep receipts, your statements help confirm dates and amounts, and they make it easier to check you haven’t missed anything.

4) Notes that explain the “why”

This is often overlooked. A short note can save a lot of time later. For example:

“Emergency plumber call-out — leak under sink at 12 High Street.”
“New fridge to replace broken one (tenant moved in same day).”

Allowable expenses: the common ones (and the common traps)

Most landlord expenses fall into familiar categories, but it’s easy to slip up in two ways: claiming something that isn’t allowable, or missing something you could have claimed.

Common allowable expenses often include:

Letting agent and management fees
Repairs and maintenance (generally, fixing what’s already there)
Landlord insurance
Safety certificates and property compliance costs
Service charges and ground rent (for leasehold properties)
Utilities and council tax only if you pay them (for example, during void periods)
Professional fees (e.g. accountancy fees related to rental accounts)

Common traps to watch for:

Repairs vs improvements: replacing like-for-like is usually a repair; upgrading or adding something new can be treated differently for tax. Keep good notes and invoices so it’s clear what you did.
Mixed-use costs: if something is partly personal (for example, a phone bill), only the business-related part is claimable.
Mortgage costs: the tax treatment here is not the same as simply claiming “mortgage payments”. If you’re unsure, ask — it’s an area where mistakes are common.

A simple bookkeeping system that works for most landlords

You don’t need a complex process. What you need is a routine you can stick to.

Step 1: Separate your property money (if you can)

If possible, use a separate bank account for rental income and property expenses. It makes bookkeeping cleaner and reduces the chance of missing costs or mixing personal spending into your property figures.

Step 2: Pick a method for capturing receipts

Choose one approach and use it every time:

Take a photo and upload it straight away
Email invoices to a dedicated “property receipts” email address
Keep digital copies in folders per property and per tax year

Step 3: Update your records little and often

Set a repeating diary slot (20–30 minutes weekly, or 60 minutes monthly). During that time:

Enter income received
Enter expenses paid
Attach receipts/invoices
Check your letting agent statement against your bank

Step 4: Keep records by property (not just by date)

This is especially helpful once you have more than one rental. It lets you see which property is profitable and which one is quietly draining cash.

Going digital: what “digital records” really mean under MTD

Under MTD for Income Tax, many landlords will need to keep records digitally and send updates through software. The practical workflow matters far more than the theory.

If you want a clear routine you can copy, this step-by-step guide is a good starting point: How to Keep Digital Records for MTD (Income Tax): A Step-by-Step Workflow for 2026–2028.

One important point: many people currently use spreadsheets. Spreadsheets may still have a place in some setups, but for many taxpayers MTD pushes you towards proper accounting software (or a spreadsheet setup with compliant bridging). This article explains why the direction of travel is clearly towards software: Why You’ll Need Accounting Software (Not Spreadsheets) for MTD Income Tax from 2026.

What about Self Assessment — do landlords still need to do a tax return?

For now, landlords still deal with Self Assessment as normal. Over time, MTD ITSA changes the process so that you submit quarterly updates and then complete an end-of-period finalisation (rather than just one annual submission in January).

If you’d like a wider overview of what MTD for Income Tax is and how it affects people in practice, this guide explains it clearly: What is Making Tax Digital (MTD) for Income Tax? A Complete 2026–2028 Guide.

A landlord bookkeeping checklist (quick and practical)

Record rent received by property and by date
Keep and file invoices/receipts for every cost
Reconcile bank transactions to your records monthly
Keep letting agent statements and match them to the bank
Make a note when a cost is unusual (e.g. part repair, part improvement)
Keep everything in one place (software or a consistent folder system)
Don’t wait until January — build a light monthly routine

When it’s worth getting help

Many landlords can manage day-to-day bookkeeping, but it’s worth asking for support if:

You have more than one property and you’re losing track
You’re unsure about what’s allowable (especially repairs vs improvements)
You have a mix of personal and property spending going through the same account
You want to get set up properly for MTD ahead of time

Good bookkeeping is about confidence. When your records are tidy, your tax return is usually straightforward, and you’re far less likely to overpay tax or end up with a nasty surprise close to a deadline.

If you’d like, we can help you put a simple system in place that fits how you actually run your rentals — and makes the move to MTD feel manageable rather than overwhelming.
