There are currently 2 deadlines for filing tax returns
If you want to, you can still file a tax return on paper, but it must be with HM Revenue & Customs by midnight on 31st October. In the rare situation where you are sent a notice to file a tax return after 31st July, then you can file it on paper within a maximum of 3 months from the date you receive the notice.
If you need or would like longer to prepare and file your return, then it can be filed up to midnight on 31st January – this is the final filing deadline for anyone who needs to submit a personal tax return. However it must be delivered online using the HM Revenue & Customs website of commercial software. At Inca all returns are filed online to speed up processing at HMRC. This is especially beneficial when a client is expecting a tax rebate.
Once again there is a special situation where an extension is allowed, specifically where the notice to file a tax return is received after 31st October. You are allowed three months to file from the date the notice is received.
If you are employed and the tax you owe is less than £2,000 then it is possible to have this collected via your salary, however, in order to do so, the return must be filed no later than midnight on 30th December.
Please remember that if your tax return is late then a fine of £100 per person, trust or partner is applicable and, most importantly, remember that the date for any tax you need to pay is the same as the filing deadline of the 31st January.
