Making Tax Digital started for landlords on 6 April 2026, and the threshold that decided it was turnover before a penny of costs came off. If your rent plus any self-employment turnover passed £50,000 on your 2024/25 return, you are already in. Property tax is all we do, and we built our own Making Tax Digital software rather than reselling somebody else's.
The awkward part is the lag: the return that puts you in scope was filed long before the obligation starts, so by the time the rules bite the number that decided it is already history.
Thresholds are qualifying income — turnover before expenses. Set by the Income Tax (Digital Obligations) Regulations 2026, reg 27.
One of them changed how you report. The other changed how much you pay. They are separate rules, they arrived years apart, and between them they explain almost every unpleasant surprise on a landlord's tax return.
From 6 April 2026, a landlord with qualifying income over £50,000 has to keep digital records and send HMRC a quarterly update on 7 August, 7 November, 7 February and 7 May. Over £30,000 joins on 6 April 2027 and over £20,000 on 6 April 2028. Each threshold is tested on the return for the tax year before the one in which it starts.
The updates are summaries of income and expenses by category rather than tax returns, and no tax is paid quarterly. The Self Assessment return still exists and is still due on 31 January — it just gets filed through MTD software instead of HMRC's online service. Missing an update costs a penalty point; four points is £200.
How MTD works for landlordsAn individual letting residential property gets no deduction for mortgage interest. Since 6 April 2020 there is only a basic rate tax reducer, worth 20% of the lowest of the finance costs, the property profit, and adjusted total income above the personal allowance. It cannot create a refund, and unrelieved finance costs carry forward.
The rate is not the worst of it. Because rent is taxed before the interest comes off, your total income is inflated by money that went straight to a lender. That is what pushes people over £50,270, over £100,000 where the personal allowance tapers away, and over the High Income Child Benefit Charge threshold — on a portfolio that produces very little cash.
Put a number on itThe point most landlords get wrong
This is the single most expensive misunderstanding in the whole regime, and it is easy to see why it happens. Every other test a landlord meets — whether there is tax to pay, whether a loss arises, what the payments on account will be — runs on profit. The Making Tax Digital test does not. HMRC measures qualifying income as your total income from self-employment and property before expenses. Turnover, in other words.
Three consequences follow, and each of them catches people out:
An illustrative example. Take a landlord with two flats producing £27,000 of rent between them, plus £26,000 of turnover from a part-time consultancy. Against the rent there is £9,000 of mortgage interest, £2,700 of letting agent fees and £2,300 of repairs — £14,000 in all, leaving £13,000 of property profit. The property business is a modest one and the consultancy is small. But qualifying income is £27,000 plus £26,000, which is £53,000, so this landlord was mandated into Making Tax Digital from 6 April 2026 on the strength of a 2024/25 return showing £13,000 of property profit. Nothing about the figures is unusual. That is rather the point.
What is not qualifying income: employment income taxed through PAYE, an individual's share of a partnership's profit, dividends including from your own company, the State Pension and private pensions. And partnerships themselves are not currently in Making Tax Digital for Income Tax, with no date set — so a portfolio held through a genuine partnership sits outside it for now.
Qualifying income of £20,000 or less is an automatic and permanent exemption, as is having no National Insurance number before the start of the tax year. There is also an application route for people who are digitally excluded — where it is not reasonable for you to use compatible software because of age, health, religious belief, or no internet access by reason of where you live. Trusts, personal representatives and non-resident companies are outside it as well.
If you would rather have the test run than described, the MTD checker asks for gross rent, any self-employment turnover and your share of anything held jointly, and tells you which April applies. It takes about a minute and asks for nothing in return.
Your mortgage is invisible to the Making Tax Digital test. Qualifying income is turnover — the rent, before a single expense comes off it.The rule that decides whether you are in, and from when
The returns, the quarterly cycle, the bookkeeping underneath it, the company side if you have one, and the two events that cost the most — incorporating, and selling.
Quarterly updates on 7 August, 7 November, 7 February and 7 May, digital records that satisfy the regulations, and the return itself filed through MTD software.
What MTD means for youProperty pages done properly: allowable expenses, the finance cost tax reducer, jointly held property and the 50:50 rule, and replacement of domestic items relief.
Self assessment for landlordsRent and costs recorded per property rather than as one lump, so a quarterly update is a submission rather than a reconstruction, and you can see which property earns.
Bookkeeping that feeds MTDStatutory accounts, corporation tax with the associated companies trap, directors' loan accounts and the real cost of taking money out since 6 April 2026.
Companies and SPVsThe arithmetic both ways, and the two costs the internet leaves out: capital gains tax on transfer at market value and stamp duty on market value.
The honest version18% and 24%, the £3,000 annual exempt amount, Private Residence Relief with its nine-month final period, and the 60-day reporting and payment window.
When you sellThe finance cost restriction is often described as a rate change, as though the only difference were 40% relief becoming 20%. It is not. It changes the figure your whole tax computation is built on, and the knock-on effects reach parts of the tax system that have nothing to do with property.
An illustrative example, on 2026/27 rates for England, Wales and Northern Ireland. A landlord earns a salary of £45,000 and receives £24,000 of rent from a residential let. Allowable expenses other than finance costs are £5,000, and mortgage interest is £9,000. The cash the property actually produces is £24,000 less £5,000 less £9,000, which is £10,000.
Had the interest simply been deductible, property profit would have been £10,000, total income £55,000 and taxable income £42,430 — giving £7,540 at basic rate plus £1,892 at higher rate, or £9,432. The restriction costs this landlord £1,800, which is 20 percentage points of the £9,000 of interest that would otherwise have been relieved at 40%.
Now look at what else moved. The salary alone was under the £50,270 higher rate threshold. It was the gross rent — including the part that went straight to the lender — that made this a higher rate taxpayer. On a larger portfolio the same mechanism reaches £100,000, where the personal allowance is tapered away, and the High Income Child Benefit Charge threshold. None of those depend on how much cash you kept.
Two things change the picture from 6 April 2027. Property income gets its own income tax rates in England, Wales and Northern Ireland — 22%, 42% and 47% — and the Section 24 reducer is given at the new property basic rate of 22% rather than 20%. Two points back against two points more on every pound of property profit is not a good trade for most people, and very little of it has been priced in yet.
The rules are the same size whoever you are. What changes is which of them reach you, and how much of the year they take up.
One property or ten, held personally or jointly. The return, the expenses, the finance cost restriction, and whether Making Tax Digital has reached you yet.
What buy-to-let landlords need →Property-level reporting rather than one merged total, the quarterly cycle run to a calendar, and incorporation modelled honestly rather than assumed.
What portfolio landlords need →Registering with HMRC, the £1,000 property income allowance, what you can actually deduct, and how much of the rent to put aside before you spend any of it.
What first-time landlords need →Higher running costs, more capital spend and a harder repairs-versus-improvements line, with the accounts kept per property so the answer is defensible.
What HMO landlords need →The Non-Resident Landlord Scheme, quarterly deductions, the NRLY return by 5 July, and the rule that every UK property disposal is reported even at a loss.
What non-resident landlords need →Corporation tax, associated companies dividing the limits, extraction after the April 2026 dividend rise, and ATED where a dwelling is worth over £500,000.
What property companies and SPVs need →Most accountants will meet MTD for Income Tax as a piece of software they bought. We built ours, which means that when something in the quarterly cycle behaves oddly we can say why rather than raise a ticket with a vendor.

Open the calculatorThat depends on your qualifying income and on which tax year it was measured in. Over £50,000 was mandated from 6 April 2026, tested on the Self Assessment return you filed for 2024/25 — so that phase is live now, not coming. Over £30,000 follows on 6 April 2027, tested on the 2025/26 return, and over £20,000 on 6 April 2028, tested on 2026/27. Qualifying income of £20,000 or less is an automatic and permanent exemption. Partnerships are not currently in Making Tax Digital for Income Tax at all, and no date has been set for them. The checker on this site runs the test in the right order and tells you which April applies to you.
Your rent. HMRC measures qualifying income as total income from self-employment and property before expenses — turnover, not profit. A landlord with £45,000 of rent and £10,000 of mortgage interest is tested on £45,000, not £35,000, so the mortgage makes no difference to whether you are in. Self-employment turnover is added to the rent: £27,000 of rent plus £26,000 from a sole trade is £53,000 of qualifying income, which is inside the £50,000 phase even though neither figure is close to it on its own. A share of jointly owned property counts as that share, so £50,000 of rent split equally between two owners is £25,000 each. Employment income, dividends, partnership profit shares and pensions do not count.
No. The return survives and the deadline has not moved: 31 January following the end of the tax year. What changes is how it is filed. Once you are mandated you send four quarterly updates during the year and then file the return itself through MTD-compatible software rather than through HMRC's online Self Assessment service. The quarterly updates are summaries of income and expenses by category, not tax returns, and you do not have to make any accounting or tax adjustments before sending one. No tax is paid quarterly. Payment dates are unchanged too: the balancing payment and first payment on account on 31 January, the second payment on account on 31 July.
Since 6 April 2020 an individual letting residential property gets no deduction for finance costs. There is a basic rate tax reducer instead, worth 20% of the lowest of three figures: the finance costs, the property business profit, and adjusted total income above the personal allowance. Where the interest would all have been relieved at 40%, the direct cost is the 20-point gap — £1,800 on £9,000 of interest. The indirect cost is usually bigger. Because rent is taxed gross of interest, your total income is higher than the cash you keep, which can push you over £50,270, over £100,000 where the personal allowance tapers away, or over the High Income Child Benefit Charge threshold. Companies, and loans wholly for commercial property, are outside the restriction.
Sometimes, and often not — which is why this site will not answer it in the abstract. Incorporating does remove the Section 24 restriction, because a company deducts interest in full. It also creates a disposal to a connected company at market value, so the whole latent gain crystallises at 18% or 24% unless incorporation relief under s.162 TCGA 1992 applies — and for transfers on or after 6 April 2026 that relief has to be claimed on your tax return rather than arriving automatically. It needs a business rather than a passive portfolio on the Ramsay test. Stamp duty is charged on market value. And extraction costs more since dividend rates rose to 10.75% and 35.75% on 6 April 2026. It helps most where profits are retained rather than drawn.
The income tax side largely does. The transaction taxes do not. Stamp Duty Land Tax applies in England and Northern Ireland only. Wales has Land Transaction Tax, with higher residential rates from 11 December 2024 and no first-time buyer relief at all. Scotland has Land and Buildings Transaction Tax with an 8% Additional Dwelling Supplement on transactions from 5 December 2024. Scotland also sets its own income tax bands — six of them — so a Scottish landlord's marginal rate is not the English one. The separate property income rates announced for 6 April 2027 cover England, Wales and Northern Ireland; nothing has been set for Scotland. Making Tax Digital for Income Tax is UK-wide.
A fixed monthly fee, quoted after a free review and agreed before anything starts. There is no price list on this site, because the fee depends on how many properties there are, whether they are held personally, jointly, through a partnership or in a company, whether we do the bookkeeping or check yours, and whether Making Tax Digital already applies. What we will not do is give regulated financial advice or mortgage advice, or tell you whether to buy, sell, gear up or incorporate. We explain how the tax works on your actual numbers and what each route costs. The investment decision stays yours, and a mortgage question goes to a broker.
A free review of your property tax position: whether Making Tax Digital has reached you, what the finance cost restriction is costing, and the two or three things worth fixing this year. If your current accountant is on top of it, we will say so.
