What it produces
- Your SA105 property pages figures, box by box
- The Section 24 finance cost calculation
- Capital gains figures where a property has been sold
- A CSV export for an accountant
What it does not do
The Tax page does not submit anything to HMRC: the SA105 figures are for a return you or your accountant file. Filing under Making Tax Digital happens on the MTD page, and only when you press send there. The distinction matters: a figure prepared for you is still a figure you are responsible for.
Making Tax Digital
Income and expenses are recorded as you go and totalled cumulatively across the quarters, which is the shape MTD for Income Tax expects. Keeping records through the year is the part that actually takes effort; the quarterly total is arithmetic once the year is recorded properly. Quarterly updates are sent from the MTD page, on every paid plan from £7.99 a month.
Which landlord software produces an SA105 property income report?
LetCompliance does. The SA105 is the UK property pages of the Self Assessment return, and LetCompliance builds its figures from the rent and costs you record as the year runs, so there is no separate year-end report to put together.
- The SA105 tax pack gives the figures box by box, for each property and in total, at your share where a property is jointly owned. It leaves out properties held in a limited company and carries UK property losses forward. It is on every paid plan, not the trial
- The SA105 spreadsheet is a CSV of every confirmed income and expense line for the tax year, each mapped to its SA105 box, with a summary. It downloads from Finance on the trial and every paid plan
- The accountant link shows your accountant the same box figures and lets them download the CSV, with no login and no way to change anything
None of these is sent to HMRC. You or your accountant put the figures on the return.
Mileage and allowances
Mileage is calculated at the HMRC rate for the tax year in question, not at the current rate. An amended return for an earlier year computes at that year’s rate, which is the correct treatment and the reason the figure sometimes differs from a calculator that only knows today.
A property you own with someone else
Record the full rent and the full costs, then open the property and set Your share for tax under Financials. The SA105 figures, the tax pack, Finance and Making Tax Digital then use your share. If you already record only your share of each amount, leave it at 100%, or your share is taken twice. If the only other owner is your husband, wife or civil partner and you live together, your share for tax is usually 50% unless you have both sent HMRC a Form 17. If someone else owns part too, there is no equal split: each owner, the two of you included, is taxed on their own share.
