This is a great way to rack up credit card rewards while paying real bills:

  • You can use it to meet the minimum spend requirement on a Mastercard credit card
  • Another application could be buying Mastercard Gift Cards as part of a separate promotion

Questions & Answers

Q: What is Plastiq and how does it work?

A: See Frequent Miler’s Complete Guide to Plastiq Credit Card Payments

Q: Is the offer targeted?

A: It initially seemed so since the email Plastiq sent announcing the promo (subject line “No Plastiq fee when you use Masterpass”) indicated the promo was only valid for accounts who received the email. But accounts that didn’t receive the email seem to be eligible as well.

Q: How to associate a Masterpass account and Mastercard with my Plastiq account to get the fee-free payments to show?

A: Create a Masterpass account if you haven’t already, then add a Mastercard to your Masterpass wallet. When scheduling a payment in Plastiq click “Add a Card” then “More Ways to Add”. When you go to pay a bill, it should then show the Mastercard associated with your Masterpass wallet and you should see a $0.00 fee for payments of $500 or less.

Q: How does the promotion work? Does the fee get refunded to you at some future date?

A: You should see the fee go to $0.00 (it’s regularly 2.5%) when you associate a Mastercard through Masterpass.

Q: Can you make multiple payments to the same payee in $500 increments without incident?

A: I scheduled a two x $500.00 payments on an automobile lease on the same day that processed successfully. I made an additional four x $500 payments to another payee that went pending the next day.

Q: Can you associate a Mastercard Gift Card with Masterpass and make payments that way?

A: I hear that you can. We’ll see whether Masterpass or Plastiq balk at that after a while.

Q: How can you make sure multiple $500 payments are applied towards a mortgage payment coming due rather than paying down principal?

A: I’ve done this in the past, and added a note saying that each payment should be applied towards my payment due on <the due date>. Not sure if that helps, but if your lender bungles it you should be able to call and get it patched up.

Q: Does Masterpass work with credit cards besides Mastercards (like Visa and AmEx?) 

A: Yes, but only payments with a Mastercard credit card quality for this Plastiq fee-free promo

Q: Plastiq charged my card right away, does that mean the payment will be sent for sure?

A: The immediate state after initiating a payment is “Card Processed”. The next state is “Sent”. In my experience, once it’s Sent it reliably goes through.

Q: I can’t think of any bills I need to pay – any ideas?

A: I think about anything I’m paying now with a check or online bill pay from checking that can’t be paid with a credit card. A few ideas:

  • Pre-paying an automobile loan or lease
  • Charitable contributions
  • Landscapers
  • Contractors [make sure you have a bill to show Plastiq if they ask]
  • Life insurance
  • Estimated tax payments to the IRS

Q: Which Mastercard credit cards offer the best rewards for this promo?

A: Some contenders:

  • At minimum you can rack up spend on reward-earning Mastercards for paying bills you’d regular pay from your checking account
  • The Citi AA cards (personal and business) seem to be matchable to 75,000 with a minimum spend requirement in the neighborhood of $4,000
  • The BofA Virgin Atlantic card has a hefty $12,000 min spend requirement for 75,000 miles
  • 2% back cards (Barclay Arrival+, Citi Double Cash)
  • The very best play may be buying MCGCs with 5% back cards at gas/grocery/drug for a 1% fee (for a 4% profit)

Q: What if I don’t have real bills to pay? Are there creative entities I can pay on Plastiq? 

A: If there are, it wouldn’t be wise to talk about them publicly. This deal is great enough as it is – I think you can get quite a bit of value out of it by playing entirely within the rules they’ve laid out. Paying a mortgage fee-free with a credit card? That’s terrific.

I’ll keep this Q&A section updated as things progress.

My Experience Using Plastiq

I’ve had a bit of a contentious relationship with Plastiq over the years.

One time they ran a promo for discounted fees when paying a mortgage. During the course of the multi-month promo, my mortgage payment increased slightly because my escrow balance was low. When I increased my payment, Plastiq saw it fit to deny me the discounted fees associated with all my payments over the course of the promotion. I objected but they didn’t care since the T&Cs said the payments needed to be for the same amount.

Another time I made a payment to a charitable organization. Plastiq took the opportunity to seek out the email address of the organization and craft an email (supposedly from the CEO of Plastiq) pitching the organization on the idea of receiving payments from Plastiq. I thought this was in poor taste [just process the payments, thanks] and indicated to me that Plastiq is using “us” to expand their database of payees.

All that said, I continue to use Plastiq trying to make money off them – just like they try to make money off me.

Summing it Up

If we look at the Net Present Value of this deal it’s pretty strong. It’s limited by scale, but if you’ve got actual bills to pay it presents a fantastic liquidation release valve.

The Probability of Malfunction of this one is that Plastiq will most likely end the offer earlier than September 30, 2018. Or at least limit the ability to make multiple $500 payments before then, leaving us with time wasted tinkering with the deal. Or possibly a handful of Mastercard Gift Cards we’ll have to liquidate elsewhere.

We’ll see, but for now if you’ve got bills you can pay [or prepay!] over the next few months this seems like a great way to do so while earning credit card rewards.

Chuck did a nice job with his post on this deal, including a link to details about the promotion seemingly intended for internal training of Plastiq employees that’s now been redirected. The comment section over there is always informative.

  1. I didnt have any real issues paying my Chase mortgage back in the day with Excite(incite? entice? excell?) Money. Multiple payments the same day would get lumped together to pay the monthly payment. The problem that may arise is multiple payments on separate days, they may get processed okay, but may require calling in to have them processed correctly, instead of principal only.

      1. I agree 100%. It is worth taking this step, even if you have to add another payment (e.g. $500, $499, $1 = $1000)

        1. Jamie: Great point, since there’s no fee why not do the extra third payment? Also, because of the way the 2.5% rounds on fractional pennies you can actually submit payments up to $500.19 for a $0 fee. ($.19 x 2.5% =.00475) That gives you some extra flexibility in hitting exact numbers. 🙂

      2. I like the coincidental Evolve Money shop talk a day after this. Standard practice here regarding payment amounts, I have also seen reference to Plastiq cancelling “duplicate” payments as well. Personally I dont mind having the last payment being >$500(mine is ~$650) and paying a bit of fees, just one less payment to get lost or show up a day late.

  2. One note, I received a bunch of errors at first while trying to link masterpass. Plastiq for some reason directed me to link masterpass via my Capital One account, but I didn’t have any eligible cards in that account. If you run into a similar issue (I’ve heard it happens for Citi as well, I think linked to cookies/what you logged in to), on the bottom right there is a button that says “Change Mobile Wallet”, click that and you can link through your regular account

    1. It’s debatable whether this deal might linger long enough for it make sense to get a MC and easily meet min spend this way.
      I’d put the over/under on this deal at around 14 days. I bet they’ll either cancel it altogether -or- limit it to one $500 payment per person (or per person per payee).

      But in the mean time, do you have any CCs that handsomely reward spend at grocery or drugstores?
      Seems like you could buy MCGCs and liquidate them paying bills this way.
      The spread could overwhelm the MCGC activation fee, plus fuel rewards discounts at grocery.

      Just a couple thoughts…

      1. Good workaround ideas! I like the way you think. I am almost finished with my Chase Freedom limit this grocery quarter, but I’m working on minimum spend for my Delta Platinum. I know AmEx is particular about GC for sign up bonus, though. Which is annoying, because I had some medical providers who do not take it and I could have knocked out spend that way.

        Will think about my other cards.

    1. Yes, you can.
      You load the MCGC like you would a credit card, by logging into your Masterpass account and adding the digits/expiration/cvv.
      Some MCGCs need to be registered for online use prior to associating them with Masterpass.

      Hope this helps.
