Hi Tommy,
No of couse I wouldn't expect an accountant to do all those things, but taxes are accountant's business. What my accountant does is insist we have a once a year meeting when I go to Ireland and we run through and discuss everything. But I'd be fairly well up on most things. I think a simple list of all the possible taxes and charges on an A4 sheet might be helpful for everybody. Especially for clients that live abroad. And maybe a link to websites like AAM.
Remember the dreaded PRTB registrations, which I nearly got caught out on myself, I had to inform Irish residents who are landlords about that as despite all the publicity people didn't know anything about it.
In relation to lettting agents or estate agents. As you probably know I wouldn't rely on them to collect rent never mind inform me of any obligations I might have as a landlord.
At the end of the day though, accountant or not, the buck will stop with me.
You can get your assistant to draft up a list, should take about half an hour, your clients will love you ! (Can't find the smiley button)
You know the list you made about dog licences or BER, they don't matter, because, there are no penalties.
