Where do I send my UK tax return?
Official HMRC Self Assessment tax return postal and courier addresses (BX9 1AS / NE98 1ZZ), paper filing deadlines, and how to file online without delays or penalties.
Short answer: Send paper UK tax returns by post to Individual Correspondence, Self Assessment, HM Revenue and Customs, BX9 1AS, United Kingdom (or Benton Park View in Newcastle for couriers). If you live abroad or moved recently, you can also file online with Matthew to submit your complete return in seconds with instant proof.
Key points
- The paper filing deadline is 31 October; the online deadline is 31 January.
- Always write your 10-digit UTR number on your return.
- If you live abroad, you need extra residence forms (SA109).
- Filing online gives you instant proof that HMRC received your return.
HMRC Self Assessment tax return address (Paper filing)
If you file on paper, always use the current HMRC address and post your forms early. Make sure to keep proof of posting.
Paper forms sent from abroad can take weeks to arrive. If the post is delayed past 31 October, HMRC will charge an automatic £100 late penalty plus interest.
By standard post (Royal Mail)
Write your 10-digit UTR number and the tax year clearly on every form and on the envelope.
By courier & special delivery (DHL, FedEx, UPS)
Couriers cannot deliver to BX postcodes. Use this street address if sending via DHL, FedEx, or UPS.
Online filing
If you have a 10-digit UTR number, you can file your tax return online until 31 January.
Filing by yourself can take hours of stressful research, especially if you have foreign income, rental property, or moved abroad. Matthew prepares and files your return for you so you know it is done right:

Non-resident returns
If you live outside the UK or moved abroad during the tax year, you must include the SA109 (residence forms) with your tax return.
HMRC's free online portal does not include these forms, which forces many people to print and post paper forms. Matthew uses HMRC-approved software to file your complete tax return and residence forms safely online in seconds.
