Can I build a good relationship with Amex by paying a large amount of taxes with the Business Plus?🔥

A 2% fee eats up most of the rebate, leaving a very thin net return.

From Amex's risk-control perspective, tax payments fall into an identifiable category, and large, recurring amounts are not necessarily viewed as high-quality spending. It's advisable to watch whether this later triggers an FR.

Property tax amounts are usually substantial, and payment processors may impose per-transaction caps or installment limits. Settlement timing can also affect the deadline, so it's best to confirm these details before proceeding.

When the main text says "basically breaking even," does that include the sign-up bonus amortized in, or does it only count everyday rewards?

The logic of building a relationship by making a large tax payment doesn't necessarily hold. Amex places more weight on your long-term spending patterns and repayment history, and a single large transaction may not change its credit decision.

But look at it from another angle: if what you really want is a better sign-up bonus next year, how much does that actually depend on how much you spend on this card this year? Or is your real goal to get a credit limit increase or avoid closing the card?

Start with a small test transaction to confirm the category and that funds arrive, then decide whether to scale up—rules vary by processor in each region.
