TaxFix discount code (UK): get 35% off with a referral code

Last updated: 26 March 2026

How to use the TaxFix discount code

Getting the discount is straightforward. Follow these steps and you should see 35% taken off at checkout:

1. Open taxfix.com/en-uk/i/STIVEN266 to start with the referral link.
2. Create your account and choose the service you need. Most people pick a Self Assessment tax return.
3. At checkout, confirm the 35% discount is showing on the total.
4. If it is not showing, enter STIVEN266 in the code box and re-check the total.
5. Pay, then complete the guided questions so your accountant can prepare and file.

As a result, the Essentials plan drops from £119 to roughly £77 with the discount applied. That gets you a UK-accredited accountant who handles the entire return from start to finish.

TaxFix promo code vs referral code

In the UK, "discount code" and "voucher code" are the most common search terms. "Promo code" is popular too, though it leans slightly more app-y. In practice, a TaxFix discount code and a TaxFix referral code point to the same discount here. The link and the code both route to the same 35% saving, so it does not matter which term you searched.

What the 35% discount applies to

According to TaxFix's new customer discount T&Cs, the referral discount applies to your first Taxfix UK service purchased. The percentage varies by referral source, which means it could differ from other links you find online. Through our referral, it should be 35% off your first tax return.

However, keep in mind that each discount applies to one service per customer and cannot be combined with other offers. You must be a new customer to qualify. TaxFix reserves the right to change or withdraw the promotion at any time.

TaxFix plans and pricing

TaxFix offers three tiers, all of which include a personal UK-accredited accountant. Here is a quick comparison:

• Essentials (from £119): Your accountant prepares and files your return, identifies eligible expenses and reliefs, answers your questions during the process, and provides a clear tax summary.
• Plus: Everything in Essentials, plus support with HMRC letters, coverage for HMRC investigations, and the option to have a consultation call to review your return.
• Platinum: All Plus features, year-round access to your accountant, HMRC agent service so they handle correspondence directly, and strategic tax-planning calls.

With the 35% referral discount, the Essentials plan becomes one of the cheapest ways to have a qualified professional handle your Self Assessment.

Why the TaxFix discount code might not show

If the discount is not appearing at checkout, there are a few common reasons. First, referral discounts are aimed at new customers only. If you have used TaxFix before, you will not qualify. Second, if you started browsing without using the referral link, open it again in a fresh tab and continue from there. Third, try a private or incognito browser window to clear any caching issues. Finally, the discount can sometimes appear late in the checkout flow, so get all the way to the final total before you assume it has not worked.

Self Assessment deadlines for 2025/26

A TaxFix discount code does not change HMRC deadlines, so make sure you know the key dates. For the 2025/26 tax year (6 April 2025 to 5 April 2026), these are the deadlines to note:

• 5 October 2026: Register for Self Assessment if you have not filed before.
• 31 October 2026: Paper tax return deadline.
• 30 December 2026: Deadline if you want tax collected through your PAYE code.
• 31 January 2027: Online filing deadline and payment deadline.
• 31 July 2027: Second payment on account for some self-employed taxpayers.

For the full official details, check Self Assessment deadlines on GOV.UK. If you want a deeper walkthrough of when and how to file, our end of year tax return guide covers everything step by step.

Making Tax Digital: what to know

From April 2026, HMRC's Making Tax Digital for Income Tax applies to self-employed individuals and landlords earning over £50,000. This means keeping digital records and submitting quarterly updates instead of one annual return. On top of that, you will still need to file a Self Assessment return for the 2025/26 tax year.

TaxFix is already rolling out MTD-compliant tools, so signing up now puts you in a good position for the transition. You can read more about MTD on TaxFix's MTD page.

FAQs

What should I search: TaxFix discount code, promo code, or referral code?

Most UK searchers type "discount code" or "voucher code". TaxFix also calls it a referral code. If you start with the link on this page, the discount usually applies automatically. If a code box appears, enter STIVEN266.

Do I need to enter a code?

Usually the referral link applies the discount on its own. If the site asks for a code during checkout, use STIVEN266 and the 35% should appear on the total.

Is it always the same final price?

Not guaranteed. TaxFix pricing, plans, and promotions can change at any time. Always trust the checkout total on the day you buy rather than any figure quoted elsewhere.

Can I file directly with HMRC instead?

Yes. Filing directly through HMRC's online portal is free, but you handle all the admin yourself. HMRC's filing guidance is here: Sending your Self Assessment tax return (GOV.UK).

How much does TaxFix cost without the discount?

The Essentials plan starts from £119. Plus and Platinum cost more but include extras like HMRC investigation cover and year-round accountant access. With the 35% referral discount, Essentials drops to roughly £77.
