Hi. My name is*****'m looking at your question now and will post my answer or ask for more information here in a short while.
You should refer to section 5 in RDR3 here and the flowchart here for information on split year treatment.
Provided that you are treated as resident in the UK for 2016/17 and 2017/18 and you meet the other criteria you should qualify for split year treatment so that the 2016/17 tax year is split into two parts, the first running from 6 April 2016 to the day before your return to the UK and the second running from the date of your return to the UK to 5 April 2017. Your foreign earnings in the first period of the 2016/17 tax year should not be liable to UK tax.
As you are planning to return to the UK in November 2016, the number of days that you will be allowed to spend in the UK and retain definitive tax free status for your foreign earnings in 2016/17 up to the date of your permanent return will be reduced from 90 to 60. See Table F on page 61 of RDR3. When you are returning to the UK, you need to qualify for split year treatment under one or more of Cases 4 to 8. See pages 59 to 69 of RDR3.
I hope this helps but let me know if you have any further questions.
Yes, you need to spend no more than 60 days in the UK in the period you mention. You should keep records of your visits to the UK in the period 6 April 2016 to 21 November 2016. You probably won't be asked to send them to HMRC. As you are already competing tax returns for your UK rental income that will continue and you will need to complete the SA109 pages for 2016/17 to claim split year treatment.
Did your family move abroad with you originally? Did you retain your UK home or was that the one that was let?
You (not your family) are limited to 60 days in the UK starting on 6 April 2015 and the the day in November before you return to the UK. That limits you to three defined ties to the UK. You can see those here (A to G). As far as I can see, you have had none of those ties to date in the period mentioned above.
Had your family stayed in the UK whilst you were abroad, they would have been a tie to the UK so the number of ties can be significant. You, however, should have no problems.
Hi.I'm just following up to find out if my answer helped or if you have any further questions.
