Plastiq, the online payment processing system that allows you to pay bills that you otherwise could not pay on a credit card for a 2.5% fee, is having trouble with many  consumer Visa credit cards. For the time being, bills paid with many (but not all) personal visa credit cards through Plastic are susceptible to one of two circumstances:

A) Getting categorized as cash advances.

For the moment at least, payments made via online payment processor Plastiq with Chase Ink Business Preferred Cards are coding under the 3x category bonus.

The 3x category bonus on the Ink Business Preferred is supposed to be for travel and shipping purchases, internet, cable and phone services, and on advertising purchases made with social media sites and search engines.

Plastiq is an online bill payment processing system that allows you to pay bills you’d normally pay in cash or with a check on a debit card (for a 1% fee) or credit card (for a 2.5% fee). Right now Plastiq is running a promotion to lower that credit card fee to 1.5% if you use your MasterCard to pay three mortgage payments before the end of 2017.

The cap you can save on fees is $200, which means the promo fee rate of 1.5% applies to just your first $20,000 in mortgage payments.

Through the end February, you can pay your bills with your American Express card via Plastiq with just a 2% processing fee instead of the usual 2.5%.

This is good news for those of you who recently signed up for Amex cards with high minimum spending requirements like the Business Platinum Card ($15,000 in three months for the 100,000 Membership Rewards) or the Business Gold Rewards Card ($5,000 in three months for 50,000 Membership Rewards).

We received a tip from a reader to check out Rentler, a platform connecting landlords and tenants that (among other things) allows you to pay rent on your credit card with a 2.5% processing fee.

You can make payments via bank transfer or debit card as well:

But it's obviously the credit card payments that interest us.
How Rentler Works
Both landlord and tenant need an account on Rentler in order to process the payment. Here's more info for tenants, and here's more info for landlords. Looks pretty simple to set up.

Regarding any information in this post about taxes: this is miles information, not tax advice. Consult a tax professional before paying your taxes with a credit card.
