Trading tax can be changed
The owner can change the buy or sell tax after you have bought.
Why it matters
A token with 0% tax today can have a 99% sell tax tomorrow, which is a honeypot with extra steps.

Who holds this power, and when it matters
This is a capability, not an event: nothing has happened to the token because of it. What it means is that a specific address can decide something about your holding later. On a regulated issuer — a stablecoin, a bank-issued token — that power is usually disclosed policy, used to comply with court orders, and the issuer has a name and an address. On an anonymous token it is the piece that turns a normal-looking launch into a trap once enough money is in. The question worth asking is not "does the power exist" but "who holds it, and what do they lose by using it".
What to check next
Look at whether ownership has been renounced, and whether it can be taken back. A renounced contract with no hidden owner cannot use owner-only powers at all — we mark that on the token page when it applies. Then look at how the supply is distributed: a power in the hands of someone who also holds most of the tokens is a much shorter path to a loss than the same power held by an issuer with a business to protect.
How to check it yourself
Everything we report can be verified without us. Open the contract on the block explorer for its chain, read the verified source if there is one, and look at the holders tab: who holds the supply, whether the pool tokens sit in a lock contract or a personal wallet. For market data, compare the pool size with how much actually trades — a pool nobody trades in is a number, not an exit.
If you are about to buy, the cheapest test is the smallest one: buy a tiny amount, then immediately try to sell it. A contract that blocks selling will tell you so for a few dollars instead of everything you were about to put in.

Questions
What does "Trading tax can be changed" mean on a token?
The owner can change the buy or sell tax after you have bought. A token with 0% tax today can have a 99% sell tax tomorrow, which is a honeypot with extra steps.
Does it mean the token is a scam?
No. It is a property of the contract or a fact about the market, read from a public source at a point in time. It is the kind of property that blocks a buyer or hands someone control over your holding, which is why we treat it as blocking — but the word "scam" is a conclusion about people, and we do not make it.
Where do you read it from?
From contract analysis (GoPlus Security), which reads the deployed contract and its authorities directly on chain.
