Can I tax my car without insurance?
If you want to drive a car on public roads, then it needs to be both insured and taxed. You don’t need to tax and insure your car if you’ve declared it off the road and made a SORN (Statutory Off Road Notification). To be able to make a SORN, you can’t keep your car on a public road; it must kept in a garage or on private land.
You can tax your car without having the insurance document to hand, but you still need to have car insurance (you just don’t need to prove it). Be aware, however, that if you’re in Northern Ireland, you’ll need a copy of your insurance certificate or a cover note if you pay for car tax at a post office.
