(daft question warning) Posting multiple self-assessment returns

SamDude

I need to post 24/25 self assessment returns for my two children. They are under 16 so it has to be done via paper forms.

Can I post both sets of printed forms in the same envelope?
(or is each envelope registered/scanned individually, causing issues with more than one return in it?)

Follow-up question - as it is only July and there is no rush to the October deadline, should I post it recorded or normal 2nd class post?

Personally - two separate envelopes and recorded delivery!

I'd definitely send them separately in the interests of clarity.

If we were closer to the deadline, recorded delivery might be worth it; but this early you can risk first class (maybe not second, the way things are going) . I've just had my notice back, they turned it around in about a week!

Thanks - I will send them separately via regular post. If I don't get an acknowledgement/response by end of August then I'll chase and repost them via recorded post.
