Recent tax legislation
The "Jobs and Growth Tax Relief Reconciliation Act" passed in 2003, and additional, related legislation since, included some significant, often temporary, and somewhat confusing changes. This is in addition to the already complex tax code changes passed by Congress in 2000. Below is a summary of the changes that impact most taxpayers in 2005.
Child tax credit: The child tax credit has been increased from $600 to $1,000 through 2010. Starting in 2010, the tax credit returns to the level originally passed in the 2000 tax bill. The credit is, however, still phased out for higher incomes.
Marriage penalty relief: The new law makes the standard deduction for married couples filing jointly and qualified widowers to be double that of single tax filers. This puts the standard deduction for 2005 at $10000. In addition to the increased standard deduction, the 15% tax bracket has been increased for married tax filers to further reduce the impact of the marriage penalty.
The 10% tax bracket: In 2004 and 2005, single taxpayers will pay 10% tax on income up to $7,150, increased from $6,000 under the old law. Likewise, married couples filing jointly will have an increase from $12,000 to $14,300.
Lower tax rates: While unchanged from 2004, the 2003 tax law accelerated rate reductions for all brackets above 15%. Below are the resulting tax rates and income ranges for 2005:
| Filing Status and Income Tax Rates 2005 | Tax rate | Married filing jointly or Qualified Widow(er) | Single | Head of household | Married filing separately |
| 10% | $0 - 14,600 | $0 - 7,300 | $0 - $10,450 | $0 - 7,300 |
| 15% | $14,601- 59,400 | $7,301- 29,700 | $10,451- 39,800 | $7,301- 29,700 |
| 25% | $59,401- 119,950 | $29,701- 71,950 | $39,801- 102,800 | $29,701- 59,975 |
| 28% | $119,951- 182,800 | $71,951- 150,150 | $102,801- 166,450 | $59,976- 91,400 |
| 33% | $182,801- 326,450 | $150,151- 326,450 | $166,451- 326,450 | $91,401- 163,225 |
| 35% | over $326,450 | over $326,450 | over $326,450 | over $163,225 |
