MTD ITSA HELP & FAQ
An Overview of HMRC MTD ITSA
HMRC now require self employed etc
Unlike MTD VAT which is quarterly, each ITSA Return you submit must be from the Tax Year Start to your chosen Period End.
Every ITSA Return you submit effectively overwrites your previous Returns in that year
You could do an ITSA Return every day if you wished, but practically, most people are going to submit 4 Returns in a year in a similar way to MTD VAT
ITSA Business Bridging Sheets
The sheet is split into 4 sections:
1) Basic Details
2) Income
3) Consolidated Expenses
4) Detailed Expenses
You should only ever link your expense figures into section 3 OR section 4, not both.
As at April 2025 you may do a 3 box return using section 3 if your total income is less than £90,000.
Basic Details
If you login with your National Insurance Number and select one of the 'Start Return' buttons, these details will be pre-filled for you.
If you download one of our macro-enabled sheets, you will need to enter these details manually
Income
Consolidated Expenses
Detailed Expenses
The expenses section has 2 columns. The first column is for your total expenses in that category, the second column is for the part of the total that is allowable as an expense to this company.
eg. If you pay £180 per year for your mobile phone and use it equally for work and personally, you might enter £180 in column 1 and £90 in column 2.

How does the Upload option work?
We now have an alternative to the old method of enabling Macros and using the 'File MY VAT Return' button
in our downloadable bridging spreadsheets
As before, you still need to link your VAT figures from your spreadsheet to ours as explained in our User Guide.
Once you are ready to submit your return:
1. Save our spreadsheet.
2. Open our Uploads page by clicking here.
3. Drag the spreadsheet into the upload box, or click the box to select the speadsheet file.
To make the upload as easy as possible, there are also Upload boxes on the Downloads page and VAT Payers page.
Macros not working / Security Risk Problems?
Microsoft and others have made an update which sets the default state to block all macros and possibly to totally block access to new spreadsheets.
You can enable access and macros for the newly downloaded spreadsheet using the notes below
OR
Avoid macro issues by UPLOADING our spreadsheet.
Please see our FAQ (above) titled "How does the NEW Upload option work?"
To fix macro issues, you may need to make one or both of the following changes.
1. If you are not being prompted to 'Enable Macros' or 'Enable Content'.
In Excel:
Click the 'file' option on the menu, then bottom left on the 'options' link.
Choose 'Trust Center', then 'Trust Center Settings' then 'Macro Settings' then choose the 'Disable all macros with notification' option.
Next time you open our spreadsheet, you should be prompted to enable content (macros).
In OpenOffice:
Click the 'Tools' menu option, then 'Options'.
In the list on the left, choose 'Security' and then 'Macro Security'.
On the 'Security level' tab choose the 'medium' setting and click 'ok' at the bottom of the dialog box.
Next time you open our spreadsheet, you should be prompted to enable macros.
2. If you see a red 'SECURITY RISK' banner across the top of our spreadsheet.
You will need to UNBLOCK ACCESS to our spreadsheet.
Open Windows File Explorer (Win+E is the shortcut), find the spreadsheet you downloaded from us (normally in your 'downloads' folder), right click the file and choose 'properties'. At the bottom of the 'General' tab on the properties popup you should have a 'security' option with an 'unblock' tick box.
My 'File My ITSA Return' button is not working?
You can use the notes below to fix the problem
OR
Avoid macro issues by UPLOADING our spreadsheet.
Please see our FAQ (above) titled "How does the NEW Upload option work?"
No response from the "File My ITSA Return" button is always one of three things.
1) You have macros disabled.
They need to be enabled for our buttons to work. To fix, save your spreadsheet (as a .xlsm file) and when you re-open it, click the 'enable editing' button and then click the 'enable macros' or 'enable active content' button (both are usually shown just below the toolbar). Please note that saving our spreadsheet as .xls or .xlsx will stop all of our buttons from working.
2) Your excel is in 'design mode'.
if this is true then clicking the button should show a border or resize blobs around the button. To fix, go to the 'developer' tab and click on the design mode icon to switch it off.
3) You have saved our spreadsheet as a .xls or .xlsx file.
If you save our spreadsheet as anything other than a macro enabled .xlsm file, Excel will remove the macros behind the buttons that are needed to make our software work correctly. The only fix is to download another spreadsheet from our website.
If you are having problems, then the simplest test of our spreadsheet is to download a new spreadsheet from:
Go to Downloads Page
Open it, enable macros, tick the declare box and Click the 'File My VAT Return' button.
Your browser should open on our confirm page, complaining about missing data. You can then close the browser tab and start linking your VAT figures to our spreadsheet.
If your browser does not open, then please Contact Us and we help to resolve the problem.
Can I use spreadsheets under MTD ITSA?
Yes, HMRC have explicitly said that recording businesses records digitally can be recorded in Excel spreadsheets providing that they are digitally linked. In order for a spreadsheet to be complaint with MTD, the initial input of the data in the first instance can be inputted manually. Any further transfer, recapture or modification of that data must be done using digital links. A digital link in this instance would simply be a formula linking a cell from one sheet to another. The use of copying and pasting, or manually creating a ITSA return is not compliant with MTD ITSA.
Who can use this software and service?
Anyone and everyone, originally devised for small businesses that used paper or spreadsheet to manage their accounts, we have farmers, barristers, engineers, tourist attractions even pension companies and software houses.
