ANNAPOLIS, Md. (AP) — Maryland residents who earn more than $100,000 annually will pay more income taxes and many will pay higher fees to flush their toilets under new laws taking effect this weekend.

Under the income-tax law, single taxpayers with an adjusted gross income above $100,000 and couples who make more than $150,000 will see their taxes rise from a quarter of a percentage point to half a percentage point. The tax increases will be retroactive to January.
