- 3% for overpayments [2% in the case of a corporation];
- 3% for underpayments;
- 5% for large corporate underpayments; and
- 0.5% for the portion of a corporate overpayment exceeding $10,000.

The standard deduction is a dollar amount that reduces the amount of income on which you are taxed. You cannot take the standard deduction if you claim itemized deductions.

Additional standard deduction amounts
The additional standard deduction amount for age, blindness, or both is specified by law and varies based on your filing status. If you are married, file a separate return, and your spouse has no gross income, you are allowed any additional amounts that apply to you or your spouse, provided your spouse is not the dependent of another taxpayer.
The additional standard deduction amounts under § 63(f) for the aged (65 or older) and for the blind are $1,050 for each, increased to $1,350 if also unmarried and not a surviving spouse.
Itemized deduction phase out
The “applicable amount” of adjusted gross income under § 68(b) (above which the amount of otherwise allowable itemized deductions is reduced under § 68) is $159,950 (or $79,975 for a separate return filed by a married individual). See Form 1040, Schedule A Instructions for the limitation amounts.

“Kiddie tax” – unearned income of minor children taxed as if parent’s income
IRS.gov
- Topic 553 – Tax on a Child’s Investment Income
- Publication 929 (2009), Tax Rules for Children and Dependents
- Form 8615, Tax for Certain Children Who Have Investment Income of More Than $1,900
The § 1(g)(4)(A)(ii)(I) amount is used to reduce the net unearned income reported on the child’s return that is subject to the “kiddie tax.” (This amount is the same as the standard deduction amount under § 63(c)(5) for an individual who may be claimed as a dependent by another taxpayer.) A child’s gross income must be more than $1,900 but less than $9,500 for a parent to elect to include a child’s gross income in the parent’s gross income and for calculating the “kiddie tax” to satisfy that requirement.
For a child to whom the § 1(g) “kiddie tax” applies, the alternative minimum tax exemption amount under § § 55 and 59(j) may not exceed the child’s earned income for the taxable year, plus $6,400.
A parent may be able to avoid having to file a tax return for the child by including the child’s income on the parent’s tax return, if specified conditions are met. The parent is the parent qualified to make the election or files a joint return with the child’s other parent To make this election, attach Form 8814 (PDF), Parents’ Election to Report Child’s Interest and Dividends.
The Small Business and Work Opportunity Tax Act of 2007 (H.R. 2206) expanded the kiddie tax to apply to children who are under age 19 or who are full-time students under age 24 (14 in 2005, under 18 in 2006).

IRS.gov
- Hope Credit Expanded, 2009 and 2010 Changes
- For more information, see chapter 2 of Publication 970, Tax Benefits for Education.
The maximum amount of the AOC increases to $2,500 per student. The credit is phased out (gradually reduced) if your modified adjusted gross income (AGI) is between $80,000 and $90,000 ($160,000 and $180,000 if you file a joint return – 2009).
The term “qualified tuition and related expenses” has been expanded to include expenditures for “course materials.” For this purpose, the term “course materials” means books, supplies, and equipment needed for a course of study whether or not the materials are purchased from the educational institution as a condition of enrollment or attendance.
The AOC can now be claimed for the first four years of post-secondary education. Previously the credit could be claimed for only the first two years of post-secondary education.
The credit is phased out (gradually reduced) if your modified adjusted gross income (AGI) is between certain amounts.
Generally, 40% of the AOC is now a refundable credit, which means that you can receive up to $1,000 even if you owe no taxes.

- EITC Information for Employers
To qualify you must work and have “earned income” from employment, self-employment or another source and meet certain rules. You must either meet the additional rules for Workers without a Qualifying Child or have a child that meets all the Qualifying Child Rules. The “earned income amount” is the amount of earned income at or above which the maximum amount of the earned income credit is allowed. The “threshold phase out amount” is the amount of adjusted gross income (or, if greater, earned income) above which the maximum amount of the credit begins to phase out. The “completed phase out amount” is the amount of adjusted gross income (or if greater, earned income) at or above which no credit is allowed. If you are married, you must file a joint return to receive the credit. You must be a US citizen or resident alien all year to qualify.
If your earned income credit (EIC) for any year after 1996 was denied (disallowed) or reduced by the IRS, you may need to complete an additional form (8862) to claim the credit.
Your qualifying child cannot be used by more than than one person. You can choose which person will claim the EIC and all of the following 5 tax benefits based on the qualifying child: child’s exemption; child tax credit; Head of household filing status; credit for child and dependent care expenses; exclusion for dependent care benefits.
To be your qualifying child, a child must be your:
- Son, daughter, stepchild, foster child, or a descendant of any of them (for example, your grandchild), or
- Brother, sister, half brother, half sister, stepbrother, stepsister, or a descendant of any of them (for example, your niece or nephew).
If your child was married at the end of the year, he or she does not meet the relationship test unless either of these two situations applies to you:
- You can claim the child’s exemption, or
- The reason you cannot claim the child’s exemption is that you gave that right to your child’s other parent under the Special rule for divorced or separated parents, described later.
Age Test – Your child must be:
- Under age 19 at the end of the year,
- Under age 24 at the end of the year and a student, or
- Permanently and totally disabled at any time during the year, regardless of age.
The instructions for the Form 1040 series provide tables showing the amount of the earned income credit for each type of taxpayer. Investment income must be less a certain amount for the year or the EIC is denied.
