New measures were introduced in 2013 to clamp down on Motor Tax evasion and drivers now have to declare cars as ‘off the road ’ before the motor tax runs out writes Suzanne Keane.   Up to July 2013 if you weren’t using a car that wasn’t taxed all you needed to do when you eventually wanted to tax it again was fill in an RF100 form, get it stamped at your local garda station and take it to the tax office with your hard earned cash! This loophole has now been closed so if your car is going to be lying idle at any point (and not taxed) you need to make sure it’s declared off the road in advance – otherwise you’ll be liable for back tax.   So how do you declare a car as off the road?

If you want to tax your car again before this time period runs out you can just fill out an RF100A form and drop it into your local...
