Company Tax Return Error 3320

[catsinspace]

Hi all,

I'm attempting to submit my 16-17 company tax return online, but it's getting rejected with error code 3320 and I can't figure out why.

The accounting period runs from 06/04/2016 to 05/04/2017 (it was aligned with the tax year a few years back) and this is the period I am attempting to file for. I have double checked the dates entered on the return and they look to be correct and match these accordingly.

Status: Rejected
Error code: 3001
Description: The submission of this document has failed due to departmental specific business logic in the Body tag.

Error code: 3320
Description: The period to which this Return's Computation applies does not coincide with the effective from/to dates of the referenced Computation Taxonomy. Please correct and re-submit.

It's a very simple/straightforward return, which I can post up in redacted form if useful. The company accounts portion of the joint filing went through OK.

If anyone has any ideas, I'd very much welcome your input.
Thanks.

My immediate thought was you are trying to file too early and HMRC corporation tax isn't available yet for FY 2017 (Which would be 1 April 2017nto 31 March 2018).

Google throws up

CCH Error 3001 & 3320 | AccountingWEB Which seems to confirm this

Also page 11 off https://www.gov.uk/government/upload...linevalids.pdf suggests out of date taxonomy on the computations, which in turn suggests strongly to me the tax computation is FY 16 (I.e. To 31.3.17) not FY 17. The taxonomy would be revised for FY17 due to reducing in Ct rate from 19% to 20%

I'm assuming you re submitting via HMRCs online services? I would wait a month and try again. It's not uncommon for systems to be una-vailabel this early in the filing cycle.

Out of interest did the computations compute 365 days @ 20% or 360 @ 20% and 5 at 19%?

Hi Jessica,
Thank you for taking the time to post up your thoughts and the links.

I was indeed filing via HMRCs online services (on 7th Apr). The tax calculation shows 360 @ 20% (FY16) and 5 at 19% (FY17).

If it's just a case of waiting it out and re-submitting when HMRC has caught up, then that's great. I guess I was just after some reassurance that it wasn't caused by something I'd overlooked/omitted during filing. My returns are usually very simple, so couldn't see where I'd gone wrong this time around.

OK, so the computation is right. HMRC just can't handle.

IMV, wait a month and try again, probably easiest. If it doesn't work then, escalate to HMRC online help desk.

If you want to you can escalate it now, but I'm 95% certain its just they are behind in updating.

Hi Jessica, it looks like you were right. HMRC have just acknowledged the issue on their service availability page.
