"Tax" shall be defined as set forth in section 235-97, HRS.
"Taxpayer" means individuals, corporations (including corporations organized under subchapter S of the Internal Revenue Code of 1986), estates, and trusts, except where the taxpayer clearly refers to only one of the preceding.
Example: R, a single individual, is employed as a carpenter. In 1993, R expects to earn $30,000 from which $2,300 in taxes will be withheld. During 1993, R also expects to earn $2,500 for carpentry performed for family and friends; no tax will be withheld.
Based on an estimated gross income of $32,500, less the standard deduction of $1,500 and personal exemption of $1,040, R's estimated taxable income is $29,960. R's estimated tax liability is $2,535.
Since the difference between R's estimated tax liability and the amount of tax withheld from R's salary is less than $500, R is not required to submit estimated tax for 1993.
If the taxpayer elects to have the preceding year's income tax overpayment credited to the current year's estimated tax liability, the taxpayer may allocate the overpayment amount either: to the first estimated tax payment, with any balance allocated to each successive quarterly payment until the overpayment amount is exhausted; or ratably allocate the overpayment amount to all estimated tax payments for the current taxable year.
If, after any available tax credit is subtracted from the estimated tax liability, the taxpayer's estimated tax liability is $500 or more, the taxpayer shall submit estimated tax payments on a quarterly basis pursuant to section 235-97, HRS, and this section.
Exemptions claimed for any children may only be claimed by the spouse who is qualified to claim the children as dependents, as provided in chapter 235, HRS. Where both spouses are qualified to claim the children as dependents, the spouses may agree as to which spouse may claim the children as dependents, or the spouses may equally divide the number of exemptions available; provided that the exemptions are not divided into fractional shares.
In the case where a husband and wife jointly file their estimated tax return, but do not choose to file a joint income tax return for the same taxable year, the estimated tax payments made for the taxable year may be credited against the tax liability of either the husband or wife, or may be divided between them in such manner as they may agree. If a husband and wife fail to agree to a division of the estimated tax payments, the payments shall be allocated between them as follows: the portion of the estimated tax payments to be allocated to each spouse shall be based on the proportionate share each spouse's tax liability bears to the combined tax liability of the spouses.
If an estimated tax return is filed jointly by a husband and wife and thereafter one spouse dies, no further payments of estimated tax are required from the estate of the decedent for the period ending on the date of the decedent's death. The surviving spouse shall remain liable for any subsequent payments of estimated tax; the surviving spouse, however, may amend the filing and choose to report the estimated tax for the taxable year separately. If the surviving spouse chooses to file separately, the estimated tax shall be computed on the aggregate taxable income of both the surviving spouse and the deceased spouse; provided the surviving spouse files a joint income tax return for the deceased spouse's last taxable year.
If the change in the taxpayer's financial circumstances which necessitates the filing of estimated tax returns occurs after May 31 but before September 1, estimated tax shall be submitted to the department in two equal payments. The first payment shall be submitted on or before September 20, and the second payment shall be submitted on or before January 20 following the close of the calendar year.
If, however, the change in the taxpayer's financial circumstances which necessitates the filing of estimated tax returns, occurs after August 31, the taxpayer may either: file an estimated tax return on or before January 20 following the close of the calendar year; or file the income tax return and submit any tax owed for the taxable year by January 31 following the close of the taxable year.
If the change in the taxpayer's financial circumstances which necessitates the filing of estimated tax returns occurs after the last day of the fifth month but before the first day of the ninth month of the fiscal year, estimated tax shall be submitted to the department in two equal payments. The first payment shall be submitted on or before the twentieth day of the ninth month; and the second payment shall be submitted on or before the twentieth day of the first month following the close of the fiscal year.
If, however, the change in the taxpayer's financial circumstances which necessitates the filing of estimated tax returns occurs after the last day of the eighth month of the fiscal year, the taxpayer may either: file an estimated tax return on or before the twentieth day of the first month following the close of the fiscal year; or file the income tax return and submit any tax owed for the taxable year by the last day of the first month following the close of the fiscal year.
In order to calculate the amount of each payment, the taxpayer should divide the total estimated tax liability for the short taxable year by the number of payment dates.
