I have just doing my tax return for 2017 on form 11. I am now retired and pay PAYE but because I have a rented property I had to use form 11 for the last number of years. My query is how much Preliminary tax I should pay for 2018 - for 2017 I paid €2000 but because I also pay PAYE I am due a refund of just over €2000 mostly due to ARF drawdown being taxed at 41% I believe that I should pay 90% of 2017 figure but because I also pay PAYE does this still apply. Also I expect my income to be lower in 2018. I would appreciate any comments.
