How can I save my declaration?

How can I save our completed online tax declaration and its appendices for future reference?

There is actually no need to do this as a copy of what you have declared, including any annexe forms you completed, is automatically retained in your personal space on the tax website under the Documents section. 

You can find copies of previous years’ declarations here too.

You can also go back into your current declaration up until its filing deadline. 

It will still be filled in with the items you declared before, but if you need to make changes you will need to click through to the end of each section again before you can sign it off again. Only the last version completed will be checked by the tax office. 

A correction service also opens in the summer,should you need to make any changes at that stage.
