Hello,
I’m assuming your position is like this:
Liability- refund (5)
Preliminary tax 2017 (2,000)
Total refund (2,005)
Following on from jpd’s post ..,
Sure you could opt to 90% of 2018 position.. this involves guess work and as your tax figures aren’t huge I wouldn’t go to the hassle of it ..
As I think you are in a refund position for 2017 before taking account of the preliminary tax paid .. you can opt to pay 100% of your 2017 liability (as per eg -5) which would be nil!!
But if I were you and not desperate for the cash I would just put the entire refund to preliminary tax. You aren’t going to get much interest in the bank anyway and it could come in handy if you had a tax bill next year... (yes it is lending money to Revenue but I’m not too worried about that ...)
The 105% option based on your 2016 liability is only available where you pay by direct debit and you have to have at least 3 payments in year 1...
Well that’s my 2 cent worth!!
