SNF Export for Preparing Self-Employed Tax Returns

Prepare sole trader self-assessments quickly using Coconut and your tax filing software in a few clicks.

Updated over a week ago

Are you filing self-assessments for your sole trader clients?

Coconut allows you to copy and paste summaries of transactions in one click by using SNF format. It means you can copy and paste the summaries directly into your major tax filing software like Taxfiler, Taxcalc and VT Software without having to do any mapping or calculations in Excel.

What is an SNF export?

SNF stands for Standard Name Format, a standard way to transfer data from accounting software to tax filing software. It was created by VTSoftware.

How do I use it?

1. Make sure the transactions are categorised correctly
On your transaction tab, you can filter by category, reviewed status or VAT rate to help you make sure the transactions are assigned correctly.

2. Click on Reports tab
Select Reports tab at the top of the Accountant Platform:

​3. Select SNF report

This will open up a modal. Select the tax year that you want to copy the data for. Preview the data, and you can click 'copy'.

By default you can preview the last tax year displayed in the modal.

4. Import into your tax filing software

Log in to your tax filing software, and go to the input page for self-employment section of the self-assessment you are filing.

Simply paste the data in the relevant input field - and the tax filing software will incorporate the data from Coconut in one click.

They'll likely round the numbers to remove the digits after the decimal point to make it compatible for HMRC.

Instructions will depend on which tax filing software you are using (see below).

How are the SNF category totals calculated?

The categories associated with each transaction in Coconut are summarised and map to the SNF categories using the following mapping:
