Thank you for your prompt reply, I can now complete and post off my return.
As mentioned my husband is on the Dutch 30% ruling (partial non-resident.) and completes a Dutch tax return each year.
He has not yet received a return from the HMRC to complete, should we ask for one? Our each half rent sum received is under £3000. If we do complete one should it be completed in the same way as mine? Thank you.
