Your tax rate depends on your filing status on your federal tax return. If your filing status is single and your annual income is $43,000, then your tax rate would be $4,481.25 + 25% of the amount over $32,550. If your filing status is married filing jointly then your tax rate would be $1,605 + 15% of the amount over $16,050. This information comes directly from the tax tables from the internal revenue website at irs.gov. If you need more information about this please let me know.
