Summary:
This article explains CalCal’s tax-return-only option for submitting a UK Self-Assessment tax return for a single tax year.
For Unlimited and Unlimited+ plan prices (£5/£50 and £8/£80), see Full accounting subscriptions.
What is the Pay-Per-Return option?
The Self-Assessment Tax Return option allows you to prepare and submit one UK Self-Assessment return for one tax year without taking out an ongoing subscription. You can select whether you want a recurring annual subscription on the payment screen.
It is designed for users who:
- Only need to file occasionally
- Are catching up on previous tax years
- Do not need ongoing accounting features
Cost
- £35 per tax year, per return
- One-off payment
- Auto-renew is optional; you can pay for one year or have your account available ongoing
What’s included
The £35 pay-per-return option includes:
- Submission directly to HMRC
- Support for common forms, including:
- SA100 – Main tax return
- SA101 – Additional information
- SA102 – Employment
- SA103S / SA103F – Self-employment
- SA105 – UK property income
- SA106 – Foreign income or gains
- SA104S / SA104F – Partnership
- SA107 – Trusts
- SA108 – Capital Gains Tax (shown in CalCal as CGT: Capital Gains Tax; available from tax year 2020)
- SA109 – Non-resident / residence status
- Validation checks before submission
What’s not included
- Ongoing accounting or bookkeeping features
- VAT returns
- MTD Income Tax quarterly updates — these need the full accounting package (Unlimited, £5/month or £50/year)
If you want ongoing access with daily ins and outs, see the Unlimited subscription instead.
How to add forms
On a legacy Self Assessment year (the year shows a forms badge), add forms like this:
- Open Tax in the sidebar, then Tax Years.
- Open the tax year and continue into SA Submission.
- Go to the Your forms step.
- Tap Select forms.
- Turn on the forms you need (for example CGT: Capital Gains Tax for SA108), then save or go back.
- Open each form from the list to complete it, then continue the return as usual.
If a form is already switched on, open it from the Your forms list — you do not need to add it again. More detail on the wizard: How to find and submit your Self Assessment return.
How it works
- Purchase the Self-Assessment return for the required tax year
- Go to https://calcal.uk/subscription-levels/self-assessment-tax-returns for more information
- Or https://calcal.uk/registration/tax-only to go straight to sign-up
- Complete the relevant sections of your return in CalCal
- Review your calculation and validation messages
- Submit electronically to HMRC
Who this option is best for
- Non-UK residents filing SA100 + SA109
- Landlords submitting SA105
- Individuals filing one-off or historic returns
- Users who don’t need ongoing accounting tools
Important notes
- HMRC requires a Government Gateway ID to submit returns electronically
- CalCal provides the software to submit your return, but does not provide personal tax advice
- If you’re unsure which forms apply to you, consult HMRC guidance or a tax adviser
- If you need to send more than one tax return for a year (eg you and your partner) you’ll need to sign up for separate accounts.
- If you need to amend a return you’ve sent either directly to HMRC or via other software, sign up then send us a ticket to mark your submission as an amendment
