Your 22/23 Tax Return

When you send us your info, it goes in the queue to do. The sooner you send it, the sooner it's done! The later you send it, the later it's done. 

Midnight on 30th September. But there's really no need to leave it that late! Get it done and out of the way asap possible please.

No. The deadline stays the same, you just know your bill sooner, so you have longer to get it paid! Sooner it's done = longer you know your tax bill and have to get it paid off.
