How much tax you pay depends on numerous variables, the first being the status you have chosen to use for filing your tax return.If you are a single individual tax payer, then there’s a certain set of rates applicable to you as indicated below.
However, if you are married and both you and your spouse have earnings to report, then the amount of tax you pay can vary depending on whether you choose to file your return as ‘married filing jointly’ or ‘married filing separately’.
Benefits of tax credits and other deductions usually have limits when filing singly, so usually couples decide to file their taxes jointly.
