gnucash-uk-vat 1.7.2

UK HMRC VAT submission bridge for GnuCash users

gnucash-uk-vat

Introduction

This is a utility which manages HMRC (UK) VAT returns in accordance with HMRC MTD directives for users of the GnuCash accounting system. It can study your GnuCash accounts, compare this with your HMRC VAT obligations, and produce the VAT return to meet your obligations. As an optional step, once the VAT return is filed, a bill can be posted describing the VAT owing, and posted to an Accounts Payable account.

There's a #gnucash-uk-vat channel on our Discord server if you want to discuss... https://discord.gg/3cAvPASS6p

A word from our sponsors :)

If you need low cost, automated accounts filing for small businesses, Accounts Machine has a commercial offering which incorporates the functionality you see here in a web service.

The proposition is simple. Accounts Machine does not offer an accounting system. You manage your accounts using GnuCash or anything which produces CSV output. You manage your accounts, manage your invoices, manage receipts, and record everything in your application under your control. When it comes to filing returns, you upload your accounts to accountsmachine.io and use the system to file VAT returns, corporation tax returns, and company accounts with Companies House. The production of returns is as automated as possible. Accounts production conforms to iXBRL specifications, and HMRC VAT MTD.

This service is able to simplify accounts filing for simple businesses. Your company should be a Limited Company, conform to micro-entity requirements, and have a single trade. This service is aimed at making life easier for startups and small businesses.

The roadmap is for launch in 2Q2022. VAT filing is complete, just going through the final validation process with HMRC. Demo is here

Visit https://accountsmachine.io. Accounts Machine is registered with HMRC and Companies House for filing purposes and have successfully filed VAT, corp tax and company accounts.

Enthusiastic early adopters will find free deal links on the Discord server. Looking forward to filing for you. :)

GnuCash backends

Two ways of interacting with your GnuCash accounts are supported:

• The gnucash module is bundled only with Linux GnuCash packages, and can only by used on Linux.
• The piecash module is pure Python and can be obtained from package repositories. This module only supports GnuCash files saved in Sqlite files or a Postgres database. You can convert a GnuCash XML file into Sqlite by using the "Save As..." option in GnuCash.

Status

This is a command-line utility, with a GTK-based dialog mode which removes the need to know about configuration files or command-line options. I have used this to submit my own VAT returns. If you want to join the party come to the #gnucash-uk-vat channel on Discord server https://discord.gg/3cAvPASS6p and I'll try to help you through the process.

Credentials

In order to use this, you need production credentials (client ID and secret) for the VAT submission API. HMRC does not permit these credentials to be shared publicly:

We have checked with our colleagues who look after HMRC’s API Platform. They have advised that this is not allowed and would be likely to result in your Developer Hub application being blocked. We recommend that instead of sharing these credentials that you inform your users how they can register for their own Developer Hub application and use its credentials with your code.

You can either apply for production credentials using the HMRC developer portal (you need to register), or contact me as I can share a few credentials privately.

Developer hub: https://developer.service.hmrc.gov.uk/api-documentation/docs/using-the-hub

You click 'Get production credentials' and enter details about the application. I call this application gnucash-uk-vat, you should call it something different. When you apply for credentials, HMRC will contact you to fill in an application. As I understand it, this involves going through a full acceptance test which involves testing against the sandbox.

Once you have credentials, you should put them in the config.json file in the application section placeholders.

Installing

To install directly from a git repository:

pip3 install git+https://github.com/cybermaggedon/gnucash-uk-vat

To install/update from the local checkout, a wrapper script can be used:

[git-bash-prompt]> ./setup.sh

See Installing.

Usage

There are two modes:

• Assist mode, which is a GTK-based dialog-driven. This automates everything including configuration file setup.
• CLI mode, which is purely CLI-based and has no dependency on PyGTK.

GnuCash accounts structure

See Accounts.

Local test service

There is a local test service which allows you to emulate the HMRC VAT service with test data under your control.

See local test.

Sample accounts

A sample account file is included at accounts/accounts.gnucash. This account file contains some transactions dated in the 1Q17 quarter which match the test data in HMRC's Sandbox. There are also some transactions in 2020 which match the obligations in the dummy-vat-service data.

Licences, Compliance, etc.

Privacy

gnucash-uk-vat is hosted by you. It runs on your computer, accesses information from your accounts, and forwards data using the HMRC APIs. Everything is within your control. No other network systems are used, and no information is transmitted to other parties.

Additional data (configuration and credentials) is stored on your filesystem under your control and you should manage the credential files as you would any password or other secret.
