If you own rental property in Lincoln and earn more than £50,000 a year from it, your relationship with HMRC is about to change. From April 2026, MTD for landlords in Lincoln becomes mandatory, replacing the once-a-year Self Assessment routine you have used for decades.

Four quarterly submissions plus a final declaration will become your new tax rhythm. Most landlords have no real idea what a quarterly update actually involves day-to-day.

This guide walks you through exactly what changes, what a real quarterly update looks like in practice using Xero, and what Lincoln landlords specifically should think about. For all the key submission dates, check our dates and deadlines page.

What is MTD for landlords?

Making Tax Digital for Income Tax requires landlords with gross property income above £50,000 to keep digital records and submit quarterly updates to HMRC using compatible software. It replaces the annual Self Assessment process for those in scope, not adds to it.

The official name is MTD for Income Tax Self Assessment, or MTD ITSA. This is different from MTD for VAT, which has been live since 2019.

You still pay your tax on the same date. The change is how, and how often, you report your figures to HMRC throughout the year. If you want a refresher on the current annual process, see our Self Assessment resources hub.

When does MTD start for Lincoln landlords?

MTD becomes mandatory in three phases based on your income level. The threshold drops each year, bringing most UK landlords into scope by April 2028.

Here is the rollout timeline:

Start Date	Income Threshold	Who is Affected
6 April 2026	£50,000+	Higher-earning landlords and sole traders
6 April 2027	£30,000+	Mid-tier landlords
6 April 2028	£20,000+	Most UK landlords

Your income is assessed across all property and self-employment combined, not per property. Joint ownership is different. Each owner is assessed individually against the threshold, based on their share.

You can verify these dates and any updates on the gov.uk MTD for Income Tax page.

What does a quarterly MTD update actually look like?

A quarterly MTD update is a digital submission to HMRC showing your cumulative rental income and allowable expenses for the tax year so far. You review your transactions, then submit summary totals through software like Xero. It usually takes between 20 and 60 minutes once your bookkeeping is up to date.

Here is what happens in practice across a single quarter:

1. Throughout the quarter, your rental income lands in your bank account and feeds into Xero automatically. Expenses are captured as you go, often through receipt photos uploaded from your phone.
2. At quarter-end, you review and categorise each transaction. A boiler repair is an allowable expense. A new kitchen is a capital improvement. Get this wrong and your tax bill is wrong.
3. You run the MTD report inside Xero, which pulls all your property income and expenses into the right HMRC categories.
4. You submit cumulative figures to HMRC through Xero’s MTD integration. No detailed receipt-level submission is required, just totals.
5. HMRC sends back an estimated tax position based on your year-to-date figures. This gives you a running view of what you will owe.

A worked example: A Lincoln landlord owns two buy-to-lets near the university. Their combined rent for the year is £42,000. In Q1, they submit £10,500 in rental income and £1,800 in expenses. By Q4, those figures have been refined three times as the picture builds.

Quarterly figures do not need to be perfect. They are cumulative and can be corrected as you go. The final declaration is where everything gets closed off properly. This rhythm only works when your bookkeeping stays up to date each month, not just at year-end.

The final declaration: what replaces your Self Assessment

The final declaration replaces your year-end tax return. It is due by 31 January following the tax year, the same deadline you know from before.

At this stage you confirm your figures, claim allowances like the mortgage interest tax credit, and declare any other income such as employment, dividends, or savings interest. This is where your tax year actually gets closed.

Think of the quarterly updates as work-in-progress reports. The final declaration is the year-end statement that triggers your tax bill.

What software do Lincoln landlords need for MTD?

HMRC requires landlords to use MTD-compatible software for their quarterly submissions. Spreadsheets alone are not enough, although bridging software can connect a spreadsheet to HMRC if you insist on that route.

The three main cloud options for landlords are:

• Xero — strong bank feeds, receipt capture, and property tracking categories
• FreeAgent — popular with smaller landlords, free with some NatWest accounts
• QuickBooks — solid all-rounder with landlord-specific add-ons

You can check HMRC’s full list of approved options on the gov.uk MTD-compatible software page.

Xero suits landlords particularly well because of its property tracking feature. You can run a separate profit and loss for each property while still submitting them as a single trade to HMRC.

Our clients run on Xero with the MTD module configured for property income. We handle the categorisation and submission so they only see a clean quarterly report. If you would rather learn the software yourself, we also offer one-to-one Xero training tailored to landlords.

Joint ownership and portfolio landlords

Joint ownership is the area most landlords get wrong. Each owner is assessed individually against the £50,000 threshold, based on their share of the rental income.

If you and your spouse jointly own a property generating £80,000 a year, you are each assessed on £40,000. Neither of you would be in scope from April 2026, although you both will be from April 2027 when the threshold drops to £30,000.

Each joint owner submits their own MTD updates. Your spouse’s submission is not your problem, and yours is not theirs.

Portfolio landlords with multiple properties treat all property income as a single trade for MTD purposes. You do not submit one return per property. You submit one combined property update each quarter.

Penalties for missing MTD deadlines

HMRC operates a points-based late submission system for MTD. Each missed quarterly deadline earns you one point. Four points triggers a £200 penalty.

Points reset to zero after a period of compliance, so a single slip-up will not haunt you forever. Repeated lateness is what costs money.

Late payment interest is separate from late submission points. If you owe tax and pay it late, interest builds up regardless of whether your submissions were on time.

The quarterly deadlines fall roughly one month after each quarter ends. Mark them in your calendar now.

Do you need an accountant for MTD, or can you DIY?

You can handle MTD yourself if you have one rental property, simple finances, confidence with Xero, and time to spare each quarter. Many landlords with a single property and a steady tenant will manage fine.

DIY stops being viable in these situations:

• You own multiple properties with different mortgage structures
• Your property is jointly owned and the income split is not 50/50
• You have mixed income types, like a Furnished Holiday Let that became a standard let in April 2025
• You have made capital improvements during the year that need careful categorisation
• You are unsure which expenses HMRC allows

An accountant adds correct categorisation, tax efficiency, and time saved every quarter. The cost is usually less than the tax you save by claiming everything you are entitled to.

At Total Accounting, we run our landlord clients on Xero with quarterly submissions handled by us. You see a clean report. We deal with HMRC. Our Lincolnshire office in Boston supports landlords across Lincoln and the wider county.

Ready for your first quarterly update?

MTD changes the rhythm of landlord tax, not the substance. The core rules on rental income, allowable expenses, and capital improvements stay the same. The difference is how often you report, and that means your bookkeeping has to keep pace.

The change is manageable. It is not something you want to figure out at 11pm the night before a deadline either.

Total Accounting runs MTD-ready bookkeeping for Lincoln and wider Lincolnshire landlords on Xero from our office in Boston. Book a 20-minute call to see what your quarterly cycle would look like with us handling it.

Already with another accountant? Switching to us is more straightforward than most landlords expect.
