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

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 quarterly figures to HMRC, so we do not need to ask you for them each time you submit data to HMRC.

I’ve filed 40 VAT Returns so far on 123 Sheets for clients, and have found it efficient, simple and easy to use.

Self Employed MTD Software – Taking the stress out of MTD compliance

All self-employed people with an income over £20,000 will soon be required to use a third-party making tax digital software for self employment (£50,000+ sales from April 2026, £30,000+ from April 2027 and £20,000+ April 2028+). As spreadsheets do not typically allow data flow to and from government servers, this requires suitable self-employed bridging software such as provided by 123 Sheets to electronically send quarterly summary data to/from HM Revenue & Customs (HMRC).

We provide ITSA MTD for self-employed taxpayers who like spreadsheets to file their MTD quarterly data to HMRC.

MTD for Self-Employed FAQ’s

How does our MTD for Income Tax Software work?

Continue to use your existing spreadsheet and insert our additional worksheet to collect summary quarterly data. Upload the spreadsheet to our website to send the quarterly data to HMRC. Users may need to update their own expense categories, to match those of HMRCs.

Alternatively, you can use one of our simple spreadsheets to enter your accounting data and send to HMRC.

All income and expense categories are pre-matched to HMRCs expense categories and our spreadsheet allows bespoke categories to be added if desired. Spreadsheets run complete ledger reports, deal simply with dis-allowable expenditure, run VAT Returns and show profit reports per self-employment for those that run multiple business units.

Some users of Sage, QuickBooks and possibly other products will use our software to export an Excel report out of their accounting software and upload that to our website in order to send data to HMRC.

What is ‘Making Tax Digital’?

There are two basic elements to this:
‍
1. You must keep your bookkeeping, through to quarterly sumbissions, on computerised systems. You cannot use paper or ledger books anymore;

2. The Tax Return self-employed government gateway website is gradually being taken down. If your bookkeeping software doesn’t have a facility for you to file quarterly Income Tax data, you will need bridging software. This is what we provide.

What Data do you Send to HMRC?

We extract out of your spreadsheet the summary income and expense quarterly totals and send those to HMRC.

HMRC do not get your spreadsheet. We do not keep anything you upload to us.

Does Your Software Last Just for a Year?

No, our software has been recognised by HM Revenue & Customs for long-term use to accept spreadsheets.

Don’t get sucked in by the tales of some software providers that spreadsheets are only a temporary solution.

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

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 your spreadsheet. You can keep these as two separate spreadsheets and use a formula to move your quarterly submission figures to our spreadsheet and just upload that to our website.

What records must you keep digitally?

There are two basic elements to this:

1. You must keep your bookkeeping on computerised systems. You cannot use paper or ledger books anymore;
2. If your bookkeeping software doesn’t have a facility for you to file your quarterly submissions, you will need bridging software. This is what we provide.

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

No. In order to file quarterly data, you will set up an account with us and enter those details there. When filing data to HMRC, we send your details and your income and expense summary totals to HMRC, so we do not need to ask you for them each time you submit data to HMRC.
