BIG NEWS: Pay HMRC with an American Express card via Bluechain

Links on Head for Points may support the site by paying a commission.  See here for all partner links.

Last year we covered Bluechain, a company which allows you to pay invoices, business or personal, with a credit card.

Bluechain charges your credit card, adds a small fee and sends a bank transfer to the company or person to whom you owe money. Easy. You can also use it to pay Council Tax.

Even better, it works with American Express as well as Mastercard and Visa.

One major snag for HfP readers was that Bluechain did not accept American Express cards for payments to HMRC – only Visa and Mastercard.

This has now changed. You can pay HMRC using an Amex card via Bluechain for a 2.3% fee.

This news may tempt you to jump on the excellent sign-up deals currently running on American Express Business Platinum and Business Gold:

  • American Express Business Platinum currently offers up to 120,000 Membership Rewards points. You receive 80,000 points when you spend £12,000 within three months and a further 40,000 points when you make a single transaction between Month 14 and Month 17.
  • American Express Business Gold – which is free for your first year – currently offers up to 60,000 Membership Rewards points. You receive 40,000 points when you spend £6,000 within three months and a further 20,000 points when you make a single transaction between Month 14 and Month 17.

If £12,000 in three months felt like too high a target for Business Platinum, this new Bluechain deal may change your mind.

The American Express card offer is valid for applications received by 8th April 2025.

What is Bluechain?

Bluechain is an online payments platform aimed at small businesses, including sole traders. It allows you to manage invoices and pay any of your suppliers with a credit card.

You can also sign up to Bluechain as a private individual.

As well as maximising your reward points, it can also help with your cashflow because of the grace period given by your credit card to settle the bill.

How does Bluechain work?

You can use Bluechain to pay any registered UK business including sole traders, local authorities (for Council Tax) and HMRC.

Bluechain takes payment from your card on the date selected, pays your invoice via a standard money transfer and – optionally – reconciles it in your accounting software when linked to Xero or Sage.

If you are a sole trader, some HfP readers have found it easier – in terms of account verification – to open a Bluechain account as a private individual and not as a business. To do this, on the page where you are asked if you are a Sole Trader or Ltd Company, just click ‘Skip’ instead.

I tested out Bluechain last month to settle the HfP PAYE bill. Whilst the Bluechain interface is not going to win any awards for user experience, I had no issues making my payment via our American Express Business Platinum card. HMRC received its money promptly and Amex treated the payment as a purchase, awarding my Membership Rewards points.

What does Bluechain cost?

Bluechain is free to join. You only pay when you make a payment through the platform.

The current payment fees are:

  • American Express 2.3%
  • Mastercard and Visa 2.5%

Is it worth the fee?

For a business – potentially yes, because the Bluechain fee is a tax deductible expense. This means that you are not paying 2.3% or 2.5% in return for your loyalty points. You can deduct your marginal tax rate.

For an individual – it is unlikely to make sense purely for the points you earn on the transaction. However …. it is very much worth it if you need some additional card spend to push you across the line for a new card sign-up bonus or an annual voucher.

Here’s a day to day spend example

Here’s an example of where it might work. American Express Business Platinum gives you 10,000 bonus points when you spend £10,000 in a calendar month.

Let’s assume your tax rate from your business is 42% including NI. If you receive a mix of dividends and salary you need to adjust this slightly.

Here’s the maths for someone who is self employed:

  • You use Bluechain to pay £9,775 to HMRC via American Express Business Platinum
  • You pay a fee of £225 which you expense to your business
  • You receive 20,000 American Express Membership Rewards points (10,000 base points and 10,000 for spending £10,000 in a calendar month)
  • Your NET fee after the tax shield is £130
  • Your ‘price per point’ is 0.65p

In this example you can ‘print’ yourself 20,000 Avios (or Virgin Points, or whatever Membership Rewards currency you want) per month for 0.65p per point via Business Platinum.

Note that there is no VAT on the Bluechain fee so a VAT-registered business does not make an extra saving.

Use Bluechain to pay HMRC with Amex

What sort of invoices can be paid via Bluechain?

Bluechain can be used to pay any registered UK business or sole trader, with the bonus of being able to pay companies, such as Google Ads, with a credit card when they no longer accept direct credit card payments.

You can also use it to pay Council Tax.

The only notable exception was that Amex was not accepted for payments to HMRC. This restriction has now been lifted.

    I used Bluechain last week to reach the £12K for the new business Platinum card I had signed up for.
    Paid £4K VAT to HMRC , and the rest were payments I would have normally made bank transfers for. The process seemed to go smoothly and the the payment to HMRC cleared quickly.
    Due to the Bluchain fee, I wouldnt make a habit of it unless there were a decent number of points to be earned from it.
    In this case it was worth it.
    25K points for a referral from my other Business Gold Amex
    10K points for spending more than £10K this month
    12K points for the actual spend
    80K points for reaching the new Amex platinum offer threshold

    Total Bluechain fees: £270.59

  • Seb says:

    Will I be able to pay my rent with it. I pay by standing order to the letting agency (will help me trigger my sign up bonus)

  • Freddy says:

    Pretty niche – users of platinum business (who aren’t spending on the card to 10k) or those who can’t spend enough to get the SUB

  • Guy says:

    Been using the Bluechain service for a while now and it’s been great. It’s even better now HMRC payments are accepted. Just be aware that there is a limit that AMEX impose on spending limits on a rolling 30 days (which is not related to your spending power). So you will need ro plan payments accordingly.

  • Ben Moore says:

    There’s a bit of a sweet spot here though at about £120k per year of spend right?

    You have a ltd co and start putting reasonable amounts of VAT and PAYE through on a biz plat card, £75k per quarter for example, then the price per point starts to look less attractive due to corporation tax relief at 25% .. if I’ve got that right!

    • Rob says:

      You need to factor in the tax you personally pay on the dividends you take too. The way the Govt set it up, corp tax + dividend tax should now equal unincorporated income tax, give or take.

    • ba says:

      £120k is the sweet spot, I think. I see no real incentive to put beyond £10k per month on this card, which leaves you with exactly 2 MR points per £1 spent.

      • Ben Moore says:

        Now if they go down the US route with no cap on tier points on the BA Amex, then it could be worth putting £300k pa and £5k fees through in exchange for Gold every year

    • The Savage Squirrel says:

      Few (genuine) businesses will have zero spend on their Biz Plat already though.
      If your ‘natural’ monthly business spend on BizPlat is, say, 7-8k then an extra 12,000 MR points for £40 of fees looks VERY attractive.

      • memesweeper says:

        If you spend £ 120,000 a year the BA Accelerating Business Amex is cheaper than Business Platinum and would earn (I think) 210,000 Avios. May be of interest to those who already have personal Platinum or just dislike the high Platinum fees.

  • Rjn21 says:

    What’s the typical time delta from credit card charge to settlement of the underlying invoice?

    For significant amounts (eg. HMRC, car, real property via a solicitor client account (!)) there is some credit risk to consider.

    Are businesses comfortable for AML purposes receiving funds from “Bluechain” where their invoice is to, say, John Smith ltd?

    • ba says:

      In my experience, it is 1 business day for approved payees (i.e. businesses that BlueChain have approved as being compliant with their T&Cs whether you have personally paid them before or not) , and otherwise 2-3 business days.

      Good point about credit risk, though I haven’t had any personal issues, and would be happy to explain the position if I ever needed to.

      To take some of your examples; payments for real property / vehicle leasing / car rental are all prohibited under the T&Cs. Car “purchases” don’t appear to be.

    • Rob says:

      It’s more about reconciliation I think, which is why you need to be very clear that you put the required reference numbers into the payment.

  • Frank says:

    Can I use a US Amex together with Bluechain to pay for my HMRC tax?

  • Inman says:

    How would refunds work with Bluechain?

    • Rob says:

      The other side can’t refund it to the same place it came from because it doesn’t have the banking details so you’d need to negotiate.
