If you are self-employed, a higher-income earner or have multiple sources of income, then you need to file a self-assessment tax return for year ended 5th April 2014 online by 31 January 2015.
For those who are not registered for online filing, the deadline for filing manual self-assessment forms passed on 30th October 2014. However, it is not too late to avoid a late filing penalty if you can register now. It would normally take HMRC 2-3 weeks to issue a UTR (Unique Tax Reference) and for you to then register in for online filing.
You can still make the 31st January 2015 deadline !
