Ftax tax returns are pdf forms which run on Adobe Reader. Sometimes the forms can become corrupt, causing them to lose their special properties, e.g. the ability to ‘Save’ form data. If this happens then download a fresh copy of the form from your Ftax Account. Adobe Reader may also become corrupt causing the form to display incorrectly. Reinstalling Adobe Reader via ‘Get Reader’ at http://www.adobe.com should overcome this problem, although you will need to go through the Ftax setup again.
Make sure you open the Ftax form into Adobe Reader and not into Preview. This is a common mistake on a Mac.
Class 1 and Class 2 National Insurance details need to be entered into the Ftax SA100 in order to correctly calculate your tax liability.
If you are self-employed or a partner and your combined profits exceed £6,475 (for 2020/21) and you have worked the full year, you will likely need to enter £159 (for 2020/21) in one of the Class 2 NI boxes.
Please note that payment of Class 1 and 2 National Insurance is not made via this self-assessment process.
Class 1 National Insurance
Class 1 National Insurance is based on your total earnings from Employment and Ministers of Religion sections, between the Primary Threshold (PT) and the Upper Earnings Limit (UEL). These details can be found on your P60.
The information must be entered into boxes on the Employment (page E1) and Ministers of Religion (page MoR1) sections of the Ftax SA100. Next to the boxes, there is a red question mark which will provide an example of how to find the relevant on your P60.
The Total NICable earnings are shown on page TR8.
Class 2 National Insurance
Class 2 National Insurance contributions are not calculated by the Ftax SA100 – they must be entered into one or more of the Self Employment (pages SES2 and SEF5), Lloyds Underwriters (page LU4) and Partnership (pages SP2 and FP2) sections of the form.
The Total Class 2 NIC are shown on page TR8.
Note 1: If you have completed any of the above sections, and your “Total Profit Less Adjustments Used For Class4 And Class2” is over the “Class 2 NIC Small Profit Threshold” (£6,475 for 2020/21), then you will likely have to pay Class 2 contributions. If you leave all the data entry boxes blank in these circumstances, then you will be warned that you might have made an error when you click Calculate on the front page.
If you do need to enter a zero figure, simply enter 0 (zero) into one of the relevant boxes. Most people over the state pension age should enter a zero figure in one of the boxes.
Note 2: If you do have to make Class 2 contributions, they will likely be £3.05 per week (£159 for a whole year) or £3.70 (£193 for a whole year) for Share fishermen, in 2020/21, but in any case should not exceed £196.10 in total (in 2020/21).
If you have been Self Employed, a Lloyds Underwriter or in a Partnership, for less than the whole year (for example, because you started part way through the year, or have reached state pension age during the year), then you will likely have paid less than a whole year’s contributions. In this case you should enter your reduced figure into the relevant box(es).
Note 3: If you have made voluntary Class 2 contributions, there is a tick box next to the Class 2 NI box which you should tick (in addition to entering the amount).
New Class 2 NIC rule
The rules for Class 2 NIC have changed for the 2023/23 tax year onwards.
Prior to the 2022/23 tax year you needed to pay Class 2 NIC if your profits were above the Small Profits Threshold, which was £6,515 in the 2021/22 tax year.
For 2022/23 onwards, you pay Class 2 NIC if your profits are above the Lower Profits Limit,(which is £11,908 in 2022/23). If your profits are below the Small Profits Threshold (£6,725 in 2022/23) then you can choose to pay voluntary Class 2 NIC. If your profits from self-employment are between the Small Profits Threshold and the Lower Profits Limit then there is no Class 2 NIC to pay – instead you will be treated as making Class 2 NIC. This will mean you will be able to access entitlement to contributory benefits in the same way as if you had paid Class 2 NIC.
For 2023/24 onwards, the Lower Profits Limit will be the same amount as the personal allowance for income tax.
You can find bookmarks to all the relevant National Insurance pages of the Ftax SA100 in the left hand bookmarks area.

If the accounting period is greater than 12 months then more than one CT600 submission will be required, as each can only be used to submit for up to 12 months. Attach the iXBRL Accounts file only to the first submission, and select the ‘PoA differs from AP-a/cs with sep rtn’ option for all other returns.
Further guidance on how to deal with computations for long accounting periods can be found in the HMRC guidance document:
After completing the form and carrying out any necessary calculations, return to the front page and click ‘Submit’. Then click ‘I Agree’ and ‘Submit Now’ before selecting ‘New’ or ‘Amend’. After several seconds an onscreen receipt will be displayed and a confirmation email sent.
If, for any reason, you are unsure about whether or not you have submitted successfully then you can submit again as New. If you have already submitted successfully then an error message will tell you so.
After clicking ‘Submit Now’ you will be prompted to select either ‘New’ or ‘Amend’.
Only submit an amended tax return if that return has already been successfully submitted. Otherwise you risk receiving a fine.
The Ftax PDF forms need to communicate with your Ftax Account to manage your data and your credits.
You must now login using your email address and password – your email is your username.
Click on the ‘?’ in a red ball, select the bottom option, and untick the box in the popup.
Enter your Ftax Account Username and Password and click ‘Login’.
If you also tick the ‘Save login details on computer’ box then the Ftax form will automatically login to your Ftax Account when it needs to.
If you have any problems please take a look at the FAQ: I cannot login to my Ftax Account. What should do?
Read the FAQ How do I setup my browser to prompt me to save downloads? and make sure you browser is set up to download and save.
Log into your Ftax Account via the Ftax website https://www.ftax.co.uk/ and look through the ‘Ftax Forms’ table.
Previously purchased forms may be downloaded via the ‘Download’ buttons.
Make sure that you download and ‘Save’ the forms files to a known folder before opening them in Adobe Reader. Ftax forms are intelligent pdf files and so can be copied and renamed if required.
Mac users need to open Ftax in Adobe Reader and NOT in Preview. To do this you can either, open Adobe Reader first and then open the form, or you can ‘right-click’ the file, select ‘Open with…’, and then select Adobe Reader.
Please ensure that you comply with the Special Notice that will be displayed when the form first opens, and log into your Ftax Account from the form when prompted.
A couple who are married or in a civil partnership may be able to transfer some unused Personal Allowance from one partner to another.
This process must be initiated by the partner transferring the allowance OUT (usually the lower or non taxpayer) to their partner.
The partner receiving the extra allowance has had a transfer IN from their partner.
The process must be done directly with HMRC either via their website https://www.gov.uk/marriage-allowance or by telephone.
The person transferring their allowance OUT will need to supply their partner’s full name, National Insurance number, date of birth and date of marriage or civil partnership.
Once HMRC has accepted the transfer, they will automatically apply the change in tax to both partners’ tax accounts.
In order for the Ftax SA100 to accurately calculate your tax due, you should record transfers (both OUT and IN) on page TR5 of the Self Assessment tax return.
If you have transferred a Personal Allowance to your spouse or civil partner, then tick Transfer OUT and complete boxes 1 to 5.
If a Personal Allowance is being transferred to you, then simply tick Transfer IN. Do NOT complete boxes 1 to 5.
Please note that a Transfer IN will only affect your tax calculation if you are not a Higher Rate tax payer and both your Married Couples Allowance and Married Couples Surplus Allowance are zero.
The best way to see Ftax in action is to look through some of our videos on this site:
If there is more than one trade to be included in the partnership tax return, then the trade with the largest turnover should be entered on the form. Other trades must be submitted as pdf attachments to this return. This can be done by completing further copies of Ftax SA800 form, and using the Pdf Copy feature to generate the simple pdfs. Each additional trade attachment must include the Partnership Statement.
If there is more than one accounting period to be included in the partnership tax return, then the main return should be completed with details for the latest accounting period. Details of other accounting periods should be submitted as attachments to this form.
This can be done by completing further copies of Ftax SA800 form, and using the Pdf Copy feature to generate the simple pdfs. Note that in the case of a construction industry trade with more than one accounting period, all subcontractor tax deducted should be shown in box 3.97.
Currently, the Ftax service will handle attachments up to a combined file size of 1M.
PDFs can be reduced in size using the free service at smallpdf.com/compress-pdf .
