Dashboard
One screen: every property with who is living there, what has come in this tax year, and a list of anything waiting for you, such as documents to check.
For landlords with a property or two
You didn’t take this on for the paperwork. Harthing keeps it for you.
Good letting, on the record.
Harthing is one quiet place for everything to do with letting a home. The certificates, the repairs, the money, the tax. You look after the property the way you always have. The record builds itself while you do it, so that if anyone ever asks you to show what happened and when, you can.
Where the rules stand now
Four things have changed for landlords, or are about to. None of them were your doing. All of them are now yours to deal with.
Making Tax Digital
Three in four landlords missed the first Making Tax Digital deadline. HMRC is now enrolling them automatically.
7 November 2026
The next quarterly update
Making Tax Digital runs on quarterly updates. From April 2027 each missed update earns a penalty point, and four points bring a £200 penalty.
1 May 2026
Section 21 abolished
Possession now runs through Section 8, and Section 8 turns on the quality of your evidence.
15 December 2026
The private rented sector database
It launches in the West Midlands on 15 December 2026 and reaches the rest of England over the following twelve months. Once the penalties are in force, they go up to £7,000.
Three things, and then it runs
This is what the record looks like from the inside. Every line is written when the thing happens, and stays exactly as it was written.
Step 01
14 September 2026, 9.04amProperty addedFlat 6, Willow Tree Court
You type the postcode and pick the address off the list. From that minute the property exists, with its own page and its own colour.
Step 02
14 September 2026, 9.18amDocument readGas safety record, K. Ellis Heating, expires 26 September
You drag in the documents you have not looked at since you filed them. Harthing reads each one, works out what it is and which property it belongs to, and shows you what it found so you can confirm it or correct it. The expiry goes in the diary at the same time.
Step 03
14 September 2026, 9.31amBank connected13 transactions categorised
You connect your bank, and the rent arriving and the bills leaving come in on their own, sorted into the categories HMRC uses. From here your quarterly update drafts itself as you go, and you send it to HMRC from Harthing when it is due.
By the end of the first sitting you have a record. From then on it fills in as you go.
Read how it works →What you actually see
Every property has a page of its own
The photograph, the tenancy, the certificates with their expiry dates, and every repair, payment and document in the order it happened. If you sell one, you archive it with a reason, and its record stays exactly as it was.
Documents
Every certificate, agreement and invoice, filed against the property it belongs to. Each one is read when it arrives and the dates are pulled out, so anything close to expiry is marked and in the diary.
The inbox
Forward an email, upload a scanned letter, or drop in a file. Each one is read, matched to a property and put in front of you to confirm or correct, as a document or as a transaction.
Maintenance
Log the problem when the tenant tells you about it, with a photograph if there is one. Assign the contractor. Mark it scheduled when a date is agreed, and done when it is done. If you decide not to act, you say why, and that stays on the record too. Every step is stamped with the time it was taken.
Finances
Rent in, costs out, each one tagged to a property and to an HMRC category. Most of it arrives on its own from your bank. A receipt or invoice you upload or forward is read and offered back to you as a transaction to confirm. You can open any one of them and change anything. The change goes on the record with the time it was made.
Taxes
Your quarterly update is drafted from your own records as the quarter goes along, with the deadline shown and the net figure kept current. When you are ready you connect to HMRC and send it. Harthing files your quarterly updates. Your end of year tax return covers all your income, from work, pensions and anything else, and Harthing only sees your property, so it cannot file that for you. It does make that return easier: the property figures from your quarterly updates are already with HMRC, and you can export the year’s records for your accountant. The return itself must go through compatible software, which your accountant or another product can do.
The Accountability Record
Everything you did right, and exactly when you did it
Everything above lands in one continuous record for each property. Entries are added, never edited and never removed. Each one is stamped with the time it was made and carries a fingerprint of the entry before it, so if a single line were altered the chain would not add up, and Harthing would say so. When you need to show your side of things, you export the lot as one document.

Making Tax Digital
HMRC closed the door to new tax filing software for this year in August. Harthing came through it.
Harthing is recognised by HMRC for Making Tax Digital quarterly updates, and files them for you. Your end of year tax return is separate, because it covers income Harthing never sees. The next quarterly update is due on 7 November 2026. In April 2027 the threshold drops to £30,000, counting your property and any self-employed income together, before expenses. Penalty points for missed updates begin at the same time.
