1 Who must pay estimated income tax.

308.1(1) General rule. For tax years beginning on or after January 1, 1990, estimated payments are required if the taxpayer’s income tax liability attributable to incomes not subject to withholding is expected to be $200 or more. The amount of estimated tax paid must be used as a credit on the taxpayer’s individual income tax return. 308.1(2) Joint estimate payments by married taxpayers. A husband and wife may make a joint estimate tax payment on one form as if they were one taxpayer. If a joint estimate payment is made, but the husband and wife elect to file separate returns or separately on the combined return form, the estimate tax paid for the tax year by the husband and wife shall be allocated between the spouses on their returns in the proportion that each spouse’s net income not subject to withholding tax relates to the combined net income of both spouses not subject to withholding tax. 308.1(3) Separate estimate tax payments by married taxpayers. A husband and wife may each make separate estimate payments. If separate estimate payments are made by married taxpayers, each spouse is to claim only the estimate payments made by that spouse. 308.1(4) Examples of types of taxpayers who may be required to make estimate payments.
