Using NAV and wanting MTD (Make Tax Digital)?

Users of Microsoft Dynamics NAV from version 2015 onwards will have received an email from Turnkey outlining the process for upgrading your NAV version to manage the requirement to Make Tax Digital and submit your VAT Returns electronically. The legislation generally applies to business submitting VAT returns after 1st April 2019.

For older versions of NAV, we are developing a solution that will require users to purchase additional “objects” to host the additional solution.

Do I Have To Use the Solution?

No, there are alternatives to a full software solution. These use a more manual approach where the data is entered into a spreadsheet and that document is updated electronically to HMRC. There are two pre-configured spreadsheet options – a paid-for version produced by accountants PWC  and a “free” version from software provider Avalara. Just click on these to take you to the solutions.

What Issues Might I Face?

There are situations where the standard Microsoft NAV functionality does not provide a 100% solution. These will require us to do some additional development. Examples are:

  1. You run multiple NAV companies which are combined into one VAT Submission; or
  2. You run one NAV company but process multiple VAT submissions per VAT entity.


Turnkey will continue to keep you updated on your options but if you have any immediate questions, please get in touch via our NAV support desk.
