Self-assessment tax returns 2016
If you need to make a self-assessment tax return this year, for income received between 6 April 2015 and 5 April 2016, you face a choice. You can fill in a traditional paper form or make an online return by logging on to the HMRC website.
Paper tax returns: 5 top tips
1. If you send a paper tax return, it must reach HMRC by 31 October 2016. If you leave things to the last moment, be sure to get proof of postage in case your return arrives late. Late returns trigger an automatic £100 fine.
2. Don’t delay sending your return for the sake of one late figure. It is acceptable to enter an estimate.
3. Don’t forget to sign your tax return. Failing to do so will invalidate your form.
4. If you find you’ve made a mistake after posting off a paper return, you can send HMRC the right figures by downloading a new tax return and printing this off. Fill in the new version and write ‘amendment’ on each page. Be sure to include your name and Unique Taxpayer Reference (UTR). You can find this on previous tax returns or letters from HMRC.
5. If you miss the October deadline, don’t post a late paper return to HMRC. Instead, you can register to file online and submit your figures before the online deadline of 31 January 2017.
