RentalBux finally gave me peace of mind.


Even after trying several tools, I was struggling with my portfolio of three rentals. MTD just added to that struggle. But then, I was introduced and all my worries disappeared. MTD submissions in minutes, track each property separately, allocate profit sharing. Wow!

As a landlord managing 12 units across two ownership structures and some self-employment income, I needed something that handled everything. RentalBux was the only software that did that.

Time saved.


Switching to RentalBux was one of the best decisions I made. Especially the joint-ownership module. Our family property had three owners with different shares, and RentalBux handled it quite efficiently.

Real challenges jointly owned property landlords face, and how RentalBux solves them

Challenges Mixed Portfolio Landlords face How RentalBux Solves It
Tracking rental income from UK and overseas properties in multiple currencies is complex. RentalBux automatically records all rental income, converts foreign currencies to GBP, and keeps UK and foreign income organised for separate and accurate quarterly updates & year-end MTD compliance.
Managing foreign property expenses, mortgage interest, insurance, and professional fees can be time-consuming and error prone. Snap receipts, upload invoices, or import statements; RentalBux categorises all expenses by property and type, including overseas costs, ensuring HMRC-compliant digital bookkeeping.
Calculating foreign tax credits and avoiding double taxation is confusing. RentalBux tracks foreign tax paid per property, organising all relevant data so you or your accountant can apply the correct foreign tax credit during the year-end final declaration.
Preparing quarterly updates and year-end final declarations for mixed UK and foreign portfolios can be overwhelming. Guided workflows, automatic reminders, and HMRC-recognised submissions make reporting for both UK and foreign rental income straightforward, accurate, and fully compliant.

Frequently Asked Questions

FAQ Section Image
Yes. For UK tax residents, the MTD threshold includes all qualifying income, combining UK and overseas properties and self-employment income if any. If your total qualifying income exceeds £50,000 in the tax year 2024/25, you must comply with MTD for mixed portfolio landlords from 6 April 2026. This requires keeping digital records of rental income and allowable property expenses, submitting quarterly updates, and completing a year-end final declaration. Foreign rental income must be converted into GBP for HMRC reporting.
MTD considers gross qualifying income, which includes all rental income from UK and foreign properties before deducting allowable expenses. This ensures that all your rental income streams are correctly assessed for digital reporting obligations.
UK tax residents can claim foreign tax relief or a foreign tax credit on overseas rental income to avoid double taxation. You must keep detailed digital records of foreign tax paid per property, along with supporting documents. These are included in the year-end final declaration, allowing your accountant or HMRC-approved MTD software for mixed portfolio landlords to calculate the correct relief for each foreign property.
Yes. While all rental income contributes to your overall MTD obligations, UK and overseas property income and expenses are reported separately in quarterly updates. For example, if you have two UK properties and one overseas property, you may submit three sets of quarterly updates, one for each property type. Digital record-keeping must clearly distinguish UK property income from foreign property income to comply with HMRC reporting rules under MTD for mixed portfolio landlords.
Some landlords may qualify for digital exemptions under HMRC rules, including those who:
  • Have health or age-related challenges making digital record-keeping difficult
  • Hold religious beliefs preventing the use of digital tools
  • Face limited internet access or technical difficulties due to location
Landlords who meet these criteria can apply to HMRC for an exemption. Otherwise, all UK tax residents with qualifying rental income—UK, foreign, or both—must comply with MTD rules from 6 April 2026 using MTD software for mixed portfolio landlords.
Yes. If you co-own foreign rental properties, each co-owner reports only their share of income and allowable expenses. The MTD threshold is assessed individually for each joint landlords, so you may need to maintain separate digital records for your portion of income and expenses for quarterly updates and the final declaration.
