Hi Kerrigan,
I admire your support for your partners friend.
Dealing with the Revenue can be extremely stressful and a protracted process, so must be a great burden on them. Ideally it would be best if somebody would act as an intermediary in dealing with the Revenue given their current health. The stress on this person is not going to help them resolve the current financial difficulties and must be having a negative impact on their business.
I suggest that this person gets their situation reviewed by MAB's or gets some other independent financial advice. On the face of it, this person isn't able to maintain two mortgages and repay a debt to the Revenue at the same time. Are their other options to consider?, could they go on interest-only on one or both mortgages so that they can repay more to the Revenue. Another thing to consider is that Revenue charge in the region of 8% interest, which is significantly greater than an average mortgage.
In relation to the Revenue debt, how does the debt arise? , is it due to this person not repaying VAT to the Revenue ?, if I understand your last post correctly it is partly due to this person not being paid and hence they are not in a position to repay the VAT to the Revenue. If that is the case the root cause of the problem is due to other people not paying their way. If that is the case I would expect there are grounds to appeal this.
It is important to understand how the debt arises before negotiating with the Revenue. If its clear cut and the money is owed to the revenue, then it would be best to work out the best repayment schedule possible and propose this to the Revenue.
If its not so clear cut, then they should have more leeway.
