In the future, you’ll need to make all tax filings via the internet. And,if you run a business, it’s likely you’ll also need to report quarterly to the HMRC.
It’s proposed that your business will have nine months after the year end to file an ‘End of Year declaration’ and submit your final figures. This is a month less than the current tax return filing deadline (currently just under 10 months following year end). But you won’t have to keep any additional paper records.
