How was the colonial boycotts an example of taxation without represenation?

The colonial boycotts were an example of taxation without representation because the British imposed new tax laws without anybody from the colonies to represent them in Britain. They had no say in any new laws, or acts, that the British imposed on them. It would kind of be like if Michigan had no representatives in Congress (which means no say in our government) and had to abide by laws they had no say in.
