Joint Property, Multiple Owners. Split Profit Automatically.

RentalBux makes joint ownership simple. Set ownership percentages for each property once during setup, and the system automatically splits all rental income and expenses according to those percentages. Each co-owner gets their own accurate reports and separate MTD submissions — no manual calculations required.

Yes -each property in your portfolio can have its own ownership structure. You might own Property A 50:50 with your spouse, Property B 60:40 with a business partner and Property C 40:35:25 with two other investors. RentalBux tracks each property's ownership separately and calculates profit splits accordingly.

Yes. RentalBux handles joint ownership splits for both UK and overseas rental properties. Each co-owner receives their percentage share of foreign rental income and expenses, ensuring correct reporting to HMRC. Foreign property income is tracked separately for accurate tax reporting.

RentalBux tracks each co-owner's share regardless of their individual MTD status. If one owner needs to submit MTD quarterly returns and another doesn't (e.g., income below the threshold), each receives the appropriate reports for their tax situation. The system accommodates different MTD requirements for different owners.

Under Making Tax Digital for Income Tax Self Assessment (MTD ITSA), each co-owner must submit their own quarterly updates to HMRC. RentalBux generates separate MTD submissions for each owner automatically — one click per owner, no duplicate data entry required.

Yes. For married couples and civil partners who own property as tenants in common, you can set unequal profit shares to reflect an HMRC Form 17 election. Simply set your specified ownership percentages (e.g., 70:30 instead of the default 50:50), and RentalBux automatically splits income and expenses accordingly.

Joint tenants own property equally (50:50) and cannot hold different shares. Tenants in common can own unequal shares (e.g., 60:40 or 70:30) based on their beneficial interest. The ownership structure can be set up either directly with the Land Registry or via a Deed/Declaration of Trust.

Please note: for spouses and civil partners, if Form 17 hasn't been submitted to HMRC, the default profit split of 50:50 applies irrespective of the actual ownership percentage.

RentalBux supports both structures — simply set your ownership percentages to match your legal arrangement.

Form 17 is an HMRC form that allows married couples and civil partners to declare an unequal split of rental income for tax purposes. By default, HMRC assumes spouses share rental income 50:50 — even if the property is owned in different proportions.

If you own property as tenants in common with unequal shares (e.g., 70:30) and want your tax returns to reflect this, you must submit Form 17 to HMRC along with evidence of your beneficial interest (typically a Deed of Trust or Declaration of Trust).

Once Form 17 is accepted, you can set your ownership percentages in RentalBux to match — and the system will automatically split income and expenses accordingly for each owner's MTD submissions.

Form 17 must be submitted to HMRC within 60 days of the declaration date. You'll need to include evidence of your beneficial interest, such as a Deed of Trust or Declaration of Trust. The form can be posted to HMRC — it cannot be submitted online. Once HMRC accepts your Form 17, update your ownership percentages in RentalBux to reflect the new split.

Beneficial ownership refers to who is entitled to the profits from a property, which may differ from legal ownership. For example, a property might be legally owned 50:50, but a Deed of Trust could specify a 70:30 beneficial interest. For tax purposes, HMRC taxes rental income based on beneficial ownership. RentalBux lets you set ownership percentages to reflect your beneficial interest.
