Software Licences based on Taxpayers Numbers, not Businesses
Unlike most of our competitors, our software licences are based on the number of taxpayer clients you have, not the number of businesses. It is not businesses that file MTD ITSA submissions, but rather taxpayers who have National Insurance numbers.
This means that a single client licence on our software will be all you need for a client who is both self-employed and has a property rental portfolio. All their required submissions will show in a single place, on our 'To Do' page, ordered by due date of submission.

MTD for Accountants FAQ’s

How does our MTD for Income Tax Software work?

down arrow

Continue to use your existing spreadsheet, just insert/link our worksheet template to your spreadsheet and upload.

Accountants using online or desktop bookkeeping apps also use our software. This might be because they need to manipulate the data in a spreadsheet prior to submission, or for cost saving reasons. In both cases, just export your summary data to Excel, then use our filing template and send to HMRC.

Altenratively, use our bookkeeping spreadsheets if you need a great spreadsheet.

What is ‘Making Tax Digital’?

down arrow

There are two basic elements to this:

1. You must keep your bookkeeping, through to the HMRC filing, on computerised systems. You cannot do it in ledger books/paper anymore;
2. You must make reqular submissions to HMRC of data which can only be sent by third-party software. This is what we provide.

What Data do you Send to HMRC?

down arrow

We extract out of your spreadsheet only the summary figures that HMRC require, not the transactional details.
HMRC do not get your spreadsheet. We do not keep anything you upload to us.

Does Your Software Last Just for a Year?

down arrow

No, our software has been approved by HM Revenue and Customs for long-term use. As long as such a thing as spreadsheets exist, our software will continue to file your data to HM Revenue & Customs.

How Do I Insert The 123Sheets Worksheet Into My Spreadsheet?

down arrow

Watch this video:
https://www.youtube.com/watch?v=BVH8e7gi9Z8

or follow these steps:

1. Ensure you have both spreadsheets open on Excel: our worksheet and your bookkeeping spreadsheet;
2. Then, click on "View" then "View Side-by-Side". You should now see both spreadsheets at the same time: one above, one below on the same page;
3. Now pick up by the tab and drop either our worksheet into your spreadsheet, or vice versa to finish.

Failing that, you do not need to merge our worksheet into yours. You can keep the two spreadsheets separate, and use a formula to move your figures to our spreadsheet and just upload that.

What records must you keep digitally?

down arrow

The bookkeeping transactions must be stored on software, this can just be a spreadsheet. There is no requirement to digitally scan your purchase or sales invoices.

Don’t I need to Put My Business Details in The Spreadsheet?

down arrow

No. In order to file a return, you will set up an account with us and enter there those details there. When filing a return to HMRC, we send those details and your figures to HMRC, so we do not need to ask you for them each time you submit a Return.

I Don’t Have Excel, Do You Work With Other Spreadsheet Software?

down arrow

Yes. Please click on the relevant software link below to see how to do it

.Google Sheets
Apple Numbers
Libre Office
Open Office

If your software is missing from the above list, let us know what it is and we’ll get back to you.

Do you Work with Sage, Quickbooks and Other Bookkeeping Software?

down arrow

Yes, we have a section above for Sage and Quickbooks. As long as your software allows you to export the Return into Excel or a .csv file, you can use our software. If it will only export a PDF, you can use a free PDF converter on the internet to convert your file into an Excel file. We are looking to increase the number of automatic imports for different software. If your software isn’t listed, get in touch, and we may be able to provide an automatic import facility for you within a week or so.

Do you Work with Different VAT Schemes?

down arrow

Yes, we work with all VAT Schemes.

FRS, Groups, Partial Exemption, Capital Goods, Margin Schemes, Cash Accounting, Annual Scheme, Retail Schemes, Payments on Account etc can all use our software.Just ensure the figures on your return are calculated correctly according to your scheme rules and are put in the correct boxes as per the rules for your VAT scheme. (Eg: on the FRS, Box 6 is the Gross Sales (inc. VAT), and Box 1 is your FRS % multiplied by your box 6 figure – other boxes are normally zero).

What Kind of Businesses do you Work With?

down arrow

We work with all sizes of businesses, organisations and individuals.

How do I Purchase Your Software?

down arrow

How Much Does it Cost?

down arrow

Find above our pricing section. Please note that our Accountant software is only for HM Revenue & Customs registered tax agents, as an Agent Services Account (ASA) is required to make filings with this account. If you have multiple businesses and are not a tax agent, please use our Business Account alternative.
