61 Pa. Code § 153.15
(a) Definitions. The following words and terms, when used in this section, have the following meanings, unless the context clearly indicates otherwise:
(b) General rule. For taxable years beginning in 1982 and thereafter, a net loss deduction will be allowed from taxable income as arrived at under section 401(3)1. of the TRC for corporations which do not qualify to allocate or apportion their income for the taxable year or from taxable income as arrived at under section 401(3)2. of the TRC for corporations which qualify to allocate or apportion their income for the taxable year.
Example 1. Corporation ‘‘A’’ has a loss of $100,000 before allocation and apportionment. Corporation ‘‘A’’ is entitled to allocate and apportion its income. Corporation ‘‘A’’ has a three factor apportionment formula percentage of 25%. Corporation ‘‘A’’ has a nonbusiness loss of $30,000 allocable to state ‘‘X’’ and nonbusiness income of $10,000 allocable to Pennsylvania. Corporation ‘‘A’’ has a net loss of $10,000, determined as follows:
| Taxable Income or (Loss) | ($100,000) |
| Less: Nonbusiness Loss Allocable to State ‘‘X’’ | ($30,000) |
| Less: Nonbusiness Income Allocable to Pennsylvania | 10,000 |
| Apportionable Business Income | ($80,000) |
| Pennsylvania Apportionment Percentage | 25% |
| Business Income or (Loss) Apportioned to Pennsylvania | ($20,000) |
| Nonbusiness Income Allocable to Pennsylvania | 10,000 |
| Net Loss | ($10,000) |
Example 2. For the 12-month taxable year ended December 31, 1986, Corporation ‘‘A’’ has taxable income, after allocation and apportionment, of $100,000. For the taxable year ended December 31, 1985, Corporation ‘‘A’’ had a net loss of $90,000. Corporation ‘‘A’’ has no other net losses.
Corporation ‘‘A’’ has a net loss deduction of $90,000 for its taxable year ended December 31, 1986.
(c) Carryover. A net loss for a taxable year may only be carried forward under the following schedule:
| Taxable Year | Carryover Period |
| 1981 | 1 taxable year |
| 1982 | 2 taxable years |
| 1983 and thereafter | 3 taxable years |
The earliest net loss shall be carried over to the earliest taxable year to which it may be carried under this schedule.
Example. For its taxable year ended December 31, 1986, Corporation A has taxable income, after allocation and apportionment of $50,000. Corporation A has the following net losses available:
| For taxable year ended | |
| December 31, 1983 | $15,000 |
| For taxable year ended | |
| December 31, 1984 | 30,000 |
| For taxable year ended | |
| December 31, 1985 | 20,000 |
| All the taxable years are full 12 month years. |
For its taxable year ended December 31, 1986, Corporation A has a net loss deduction of $50,000. The deduction consists of the $15,000 net loss from taxable year 1983, the $30,000 net loss from taxable year 1984 and $5,000 of the net loss from taxable year 1985.
The remaining $15,000 of net loss from taxable year 1985 is available for carryover to Corporation A’s next 2 taxable years.
