When is my self employed tax payment due?

[FreelanceSoftwareDeveloper]

I am getting conflicting messages from within the HMRC website regarding the due date for my 2014/15 self employed tax return which I have recently submitted online.

The Self Assessment homepage states:

£xxx.xx due by 31 January 2016 | 21 days left
Bill details
-> £xxx.xx Balancing payment

The Business Tax Dashboard sates:

You have nothing to pay.
GBPxxx.xx will become due for payment on 31 Jan 2016.

The actual amount is the same in all areas.

If it's relevant, I am currently paying my 2013/14 self employed tax from this years PAYE in my other job.

I thought the submission date was end on January (for online) then I would have until end of March or July to pay the tax owed? It's not a significant issue as I do have the funds to pay it and I certainly don't want to get any unnecessary fines added, but I'd rather have it my account for as long as possible!

You have to file your tax return by 31 January to avoid penalties. You also have to pay the tax due by that date to avoid penalties.

The messages are not conflicting. Your tax for 2014-15 is due on 31 January.
The current message is that you have nothing to pay - that's correct at today's date as the tax isn't due until the 31st. It does tell you that
