Maybe. I'd be comfortable calling it a subsidy if it's a very specific break given to a narrow segment of the economy. So no I wouldn't call the infinite taxes you're not paying a "subsidy", but if you're paying lower taxes than I am because the government has chosen to tax me at a higher rate than you, I might call the difference a subsidy. BTW, I'm not necessarily opposed to subsidies, there can be good reasons to do this.
