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.

Alternatively, 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 regular 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.

If the above process doesn't work, you can keep the two spreadsheets separate and use a formula to move your figures to our spreadsheet and just upload our spreadsheet.
