Landlord Tax Deadline: Key Dates, Penalties and MTD Rules

The main landlord tax deadline is 31 January, when you must file your Self Assessment tax return and pay any tax owed for the previous tax year. Paper returns are due earlier, by 31 October. A second advance payment, known as a payment on account, is due by 31 July.

If you want tax collected through your PAYE tax code instead of paying it in one go, your online return needs to be in by 30 December.

Two landlords who miss a payment by exactly the same number of days can now end up with two different penalties, because from April 2026 HMRC split Self Assessment into two separate systems.

If your rental income is under £50,000, you’re still on the traditional deadlines and penalties that have applied for years. If it’s over that threshold, you’ve moved into Making Tax Digital, with its own quarterly reporting schedule and a different way of working out what’s owed if you’re late.

Either way, the landlord tax deadline that matters most hasn’t changed: 31 January, for filing and paying.

This guide sets out the UK landlord tax deadline in full: every date landlords need to know, what happens if one is missed, and how the 2026 changes affect payment on account and penalties along the way.

Key Landlord Tax Deadline Dates

Working out the exact deadline to pay landlord tax comes down to how you file and how much you owe, but the underlying dates are fixed every year.

HMRC’s tax year runs from 6 April to 5 April the following year, and landlords pay tax on their rental profits for that period after it ends.

For the 2025/26 tax year (6 April 2025 to 5 April 2026), for example, the online filing and payment deadline is 31 January 2027.

The key dates to plan around each year are:

• 5 October: register for Self Assessment if this is your first year as a landlord and you haven’t filed before.
• 31 October: deadline for a paper tax return.
• 30 December: deadline to file online if you want tax collected through your PAYE tax code (only available if you owe less than £3,000 and meet HMRC’s other conditions).
• 31 January: deadline to file online and to pay any tax owed for the year.
• 31 July: deadline for your second payment on account, where applicable.

Together, these make up the landlord tax payment dates you need in your diary. Miss any of them and the consequences differ depending on which one it is.

If you’re registering for the first time, HMRC posts your Unique Taxpayer Reference and activation codes, which can take a couple of weeks to arrive, another reason it pays to track every HMRC landlord tax deadline well ahead of time, especially the 5 October registration cut-off.

Miss the payment deadline and a penalty of 5% of the unpaid tax applies once you’re roughly a month overdue, with further 5% charges at six and twelve months.

That’s explained in full further down, because for some landlords, a different penalty system now applies instead.

How to Pay Landlord Tax: PAYE or Self Assessment

There are two main ways to pay landlord tax: through Self Assessment directly, or, if you’re also employed or receive a pension, through PAYE (Pay As You Earn, the system that collects tax automatically from wages before you’re paid).

To pay via PAYE, you need to owe less than £3,000 in tax on your rental income, and you’ll usually still need to complete a Self Assessment tax return unless HMRC tells you otherwise.

If you qualify, a landlord PAYE tax payment gets added to your tax code and collected in equal instalments from your salary or pension over the following year, rather than as one lump sum.

Otherwise, your tax bill is paid directly through your personal tax account by 31 January.

The account shows the payment options available (usually bank transfer, debit card, or a bank’s own faster payment service) and the amount due updates automatically once you’ve filed your return.

Payment on Account Explained for Landlords

If your Self Assessment tax bill is more than £1,000, HMRC usually asks for tax in advance through payments on account, unless more than 80% of your tax is already collected some other way, such as through PAYE.

The second payment on account landlord deadline of 31 July often catches people off guard, because it isn’t linked to when you filed your return. It’s fixed regardless.

Each payment on account is half of your previous year’s tax bill. You pay the first instalment alongside your balancing payment on 31 January, then the second on 31 July.

Say your tax bill for one year came to £2,000: you’d pay £1,000 as a payment on account in January, on top of anything still owed from the previous year, then another £1,000 in July.

When you file the following year’s return, HMRC works out your actual bill and either asks for a top-up (a ‘balancing payment’) or refunds the difference.

If you expect your income to fall, you can ask HMRC to reduce your payments on account using form SA303 or through your online account. Reduce it by too much, though, and you’ll be charged interest on the shortfall once your real bill comes in.

Landlord Late Payment Penalty: What You Risk

Missing the landlord self assessment deadline of 31 January can trigger two separate sets of landlord tax penalties (one for filing late, another for paying late) and it’s possible to be hit with both at once.

For late filing, HMRC charges an automatic £100 fixed penalty the moment you miss the landlord tax return deadline, even if you don’t owe any tax or you’ve already paid it.

If your return is still outstanding after three months, daily penalties of £10 apply, up to a maximum of £900. Miss it by six or twelve months and further charges apply too, worked out as a percentage of the tax due or a flat amount, whichever is higher.

For late payment, a separate penalty applies: 5% of the tax you owe once you’re around a month overdue, a further 5% if it’s still unpaid after six months, and another 5% after twelve months. On top of the penalties, interest accrues daily on whatever’s outstanding, currently 7.75% a year.

These are the rules for landlords under the Making Tax Digital threshold. If you’re mandated into MTD, a different late-payment system applies instead, covered in the next section.

Making Tax Digital for Landlords: 2026 Changes

MTD for landlords 2026 marks the first year Making Tax Digital for Income Tax became mandatory, applying to anyone with combined gross income from property and self-employment above £50,000 in the 2024/25 tax year.

The threshold drops to £30,000 from April 2027, and is expected to fall again to £20,000 from April 2028, though that final step still needs further legislation to confirm it.

Instead of filing one annual return, landlords within MTD keep digital records using MTD-compatible software and send HMRC a quarterly summary of income and expenses, followed by a year-end final declaration by 31 January, in the same way as before.

The penalty system changes too. Late submission moves to a points-based system: you get a penalty point for each missed deadline, and only once you reach four points does a £200 fine apply.

There are no penalty points for late quarterly updates during the first year (2026/27), giving new joiners some breathing room while they adjust.

Late payment penalties work differently as well: instead of the 5% milestones above, MTD-mandated landlords get a grace period of 30 days in their first year (15 days after that) before a penalty starts to apply, calculated as a percentage of what’s outstanding.

HMRC publishes the exact current rate, which has changed more than once as the system has rolled out, so it’s worth checking your online account for the figure that applies to your situation.

If You Can’t Pay Your Landlord Tax Bill on Time

If you know you won’t be able to pay by the deadline, contacting HMRC before it passes is worth doing rather than waiting to see what happens.

HMRC’s Time to Pay service lets you spread what you owe into instalments, and you can usually set this up online if you owe less than £30,000 and meet the other conditions.

Setting up a Time to Pay arrangement doesn’t stop interest building up on the outstanding balance, but it does mean penalties are generally paused as long as you keep to the agreed schedule (and frankly, the earlier you get in touch, the more options HMRC tends to offer).

What to Do Next

The landlord tax deadline that matters most for almost everyone is 31 January. This rental income tax deadline covers both filing your Self Assessment return and paying any tax owed, alongside a second payment on account due the following 31 July if it applies to you.

If your rental income is over £50,000, check whether you’re now within Making Tax Digital, since the reporting schedule and some of the penalty rules are different from what you may be used to.

If you think you’ll struggle to pay on time, contacting HMRC before the deadline passes, rather than after, gives you the most options.

Key Takeaways

The main points to consider:

• The main landlord tax deadline is 31 January, covering both filing your Self Assessment return and paying any tax owed.
• Paper returns are due earlier, by 31 October; first-time landlords need to register by 5 October.
• Payments on account, where they apply, are split between 31 January and 31 July, each worth half of your previous year’s tax bill.
• Landlords with rental income over £50,000 have been inside Making Tax Digital since April 2026, with quarterly reporting and a different penalty structure from the traditional system.
• Late filing and late payment penalties are charged separately, and it’s possible to face both if you miss the deadline entirely.
• If you can’t pay on time, HMRC’s Time to Pay service can spread the cost and may pause penalties while you stick to the plan.

Common landlord tax deadline questions

HMRC guidance and the wider Self Assessment rules raise a few follow-up questions landlords often have once the main self assessment deadline for landlords is clear.

When is landlord tax due if I’ve never filed before?

If this is your first tax year as a landlord, the clock starts differently. You need to tell HMRC you need to complete a Self Assessment return by 5 October following the end of the tax year in which your rental income started. For example, if you began letting a property in the 2025/26 tax year, you’d need to register by 5 October 2026.

Once you’ve registered, HMRC sends a Unique Taxpayer Reference and activation codes by post, which can take a couple of weeks to arrive. The filing and payment deadlines that follow are the same as for any other landlord: 31 October for a paper return, or 31 January for filing and paying online, the same rental income self assessment deadline everyone else works to.

What’s the difference between the tax return deadline and the tax payment deadline?

For most landlords filing online, these landlord tax return dates fall on the same date (31 January), which is part of why the two get treated as one deadline. But they’re legally separate obligations, and HMRC penalises them separately too.

If you file a paper return, though, the return deadline moves to 31 October while the payment deadline stays at 31 January. That means it’s possible to file well ahead of paying, but not the other way round. Payment is always due by 31 January regardless of when or how you filed.

How do I pay tax on rental income as a non-resident landlord?

Non-resident landlords still pay tax on rental income UK properties generate, and register with HMRC and file a Self Assessment return covering that income, following the same key dates as UK-resident landlords. Depending on how the rental income is managed, tax may also be deducted at source by a letting agent or tenant under HMRC’s non-resident landlord rules, with any balance settled through the Self Assessment return.

The registration, filing and payment deadlines don’t change based on residency: 5 October, 31 October and 31 January still apply. What differs is the paperwork involved in setting up how tax is collected, which is worth sorting out well before the registration deadline if it applies to a property owned from overseas.

Can HMRC change my payment on account amount without telling me?

Payments on account are set automatically once your tax bill crosses the £1,000 threshold. HMRC doesn’t ask permission first, since the amount is simply based on your previous year’s bill. You’ll see the amounts due on your Self Assessment statement or online account, generally well ahead of the January and July deadlines.

If your circumstances change and you don’t act, the automatic figure stands, and interest can build up on the difference if it later turns out to be wrong in HMRC’s favour. Landlords who know their income has genuinely dropped are better off applying to reduce their payments on account proactively, rather than assuming HMRC will adjust things automatically.

Does the landlord tax deadline change if 31 January falls on a weekend?

No. HMRC’s Self Assessment deadlines are set by date, not by working day, so if 31 January falls on a Saturday or Sunday, the deadline doesn’t move. Payment and filing are both still due by 11:59pm that day.

This matters most for payment methods that take a day or two to clear, such as some bank transfers. Faster payment options, or paying a few days early, remove any risk of a payment technically arriving after the deadline even though it was sent in good time.
