Just realized something that hasn't been clearly stated in our replies, and which might help remove (or add) some confusion. I'll a little rusty on the UK stuff - haven't lived there for 30 years, so feel free to correct my statements below. Unlike the UK, in the US, registrations and licenses are handled separately by each state and, since the details may vary, I'll cover only California.
In California:Vehicle registration happens when a vehicle is purchased new, or when ownership is transferred to another party. At that time, the owner (or new owner) receives a certificate of ownership aka the title document, affectionately called the pink slip. In the case of a vehicle financed through, say, a bank, the pink slip is held by the bank until the loan has been paid off.
The owner also receives a registration card (usually a piece of paper), confirming the registration fees have been paid, along with one or two self-adhesive tags that are attached to the rear license plate. One tag would show the year and the other the month of expiration. If bought through a dealer, the dealer would issue a temporary registration card (piece of paper) that is attached to the inside of the windshield by Scotch tape, pending receipt of the official paperwork form DMV. The registration is renewed annually, and results in a new registration card and a new tag showing the year of expiration.
Renewals can be done online, provided smog test results are on file at the DMV. Smog is not required on new vehicles, but is required every two years after year 5.
In the UK:Registration occurs when a vehicle is purchased new or transfers ownership, but is not renewed annually. What happens annually is the purchase of a road fund license aka payment of a road tax. New registration results in the owner receiving a "log book", which nowadays is IIRC a piece of paper, and is the title document. The owner also receives a "tax disc", which is (or used to be) a circular piece of paper attached to the inside of the windshield, usually in a special-purpose "tax disc holder". When the license (aka road tax) is renewed, a new tax disc is issued.
I either don't recall or never knew what happens in the case of a vehicle being financed by a bank. My cars were usually old bangers that no bank manager or loan officer in their right mind would finance.
I've read somewhere that "road fund license" and "road tax" are no longer the correct terms, but us old folks don't re-calibrate easily.
Phew! Turned out to be longer than I expected; Hope nobody fell asleep or became more confused
