2018 Instructions for Schedule S Other State Tax Credit

General Information

In general, for taxable years beginning on or after January 1, 2017, Indiana will no longer be treated as a reverse credit state for California tax purposes. California residents that derived income from sources within Indiana and paid a net income tax to Indiana on income that is also taxed by California, may claim the other state tax credit. California nonresidents may not claim the other state tax credit for net income taxes paid to Indiana.

For taxes paid to another state on or after January 1, 2009, a claim for credit or refund of an overpayment of income tax attributable to taxes paid to another state may be filed within one year from the date tax is paid to the other state or within the general statute of limitations, whichever period expires later.

Taxpayers may qualify for a credit for income taxes paid to another state when the same income that is taxed by the other state is also taxed by California. Other state income taxes which are paid to the other state do not necessarily have to be in the same year, as long as the taxes relate to the same transaction.

You must attach Schedule S, Other State Tax Credit, and a copy of your tax return(s) filed with the other state(s) to your California tax return. Retain a copy of other state tax returns, along with a copy of this form for your records.

Shareholders of S corporations, partners of partnerships, and members of limited liability companies (LLCs) classified as partnerships for tax purposes, see Section G, Pass-Through Entities, for more information.

A. Purpose

If you are an individual filing a California personal income tax return or an estate or trust filing a California fiduciary income tax return, use Schedule S to claim a credit against California tax for net income taxes imposed by and paid to another state or U.S. possession.

Generally, residents of California may claim a credit only if the income taxed by the other state has a source within the other state under California law. (This does not apply for dual-resident estates and trusts. See Section F, Dual-Resident Estates and Trusts for additional information on determining dual-residency). No credit is allowed if the other state allows California residents a credit for net income taxes paid to California.

Nonresidents of California may claim a credit only for net income taxes imposed by and paid to their states of residence and only if such states do not allow their residents a credit for net income taxes paid to California.

Important: See Sections C, California Residents, and D, California Nonresidents, for a list of states and U.S. possessions for which the other state tax credit is allowed. See Section H, Income from Sources Within the Other State, for a description of the source of various types of income.

Beneficiaries of estates or trusts, partners of partnerships, members of LLCs classified as partnerships, and shareholders of S corporations that paid a net income tax (or gross income tax for shareholders of S corporations) to another state on income that must be reported to California may also claim the other state tax credit. See Sections F, Dual-Resident Estates and Trusts, and G, Pass‑Through Entities, for more information.

B. Application of the Credit

Credit is allowed for net income taxes paid to another state (not including any tax comparable to California’s alternative minimum tax) on income that is also subject to California tax. The credit is applied against California net tax, less other credits. The credit cannot be applied against California alternative minimum tax.

When a joint tax return is filed in California, the entire amount of tax paid to the other state may be used in figuring the credit, regardless of which spouse/RDP paid the other state tax or whether a joint or separate tax return is filed in the other state.

When a joint tax return is filed in the other state and separate California tax returns are filed, the credit is allowed in proportion to the income reported on each California tax return.

If, after paying tax to the other state, you get a refund or credit due to an amended tax return, computation error, audit, etc., you must report the refund or credit immediately to the Franchise Tax Board (FTB). Prepare a revised Schedule S and attach it to any of the following:

  • Amended Form 540, California Resident Income Tax Return, or amended Long Form 540NR, California Nonresident or Part-Year Resident Income Tax Return. Check the “AMENDED return” box at the top of Side 1.
  • Amended Form 541, California Fiduciary Income Tax Return. Check “Amended tax return” box below fiduciary address area on Side 1.

C. California Residents

California resident individuals, estates, or trusts that derived income from sources within any of the following states or U.S. possessions and paid a net income tax to that state or U.S. possession on income that is also taxed by California may claim the other state tax credit:

Alabama (AL), American Samoa (AS), Arkansas (AR), Colorado (CO), Connecticut (CT), Delaware (DE), District of Columbia (DC) (unincorporated business tax and income tax, the latter for dual residents only), Georgia (GA), Hawaii (HI), Idaho (ID), Illinois (IL), Indiana (IN), Iowa (IA), Kansas (KS), Kentucky (KY), Louisiana (LA), Maine (ME), Maryland (MD), Massachusetts (MA), Michigan (MI), Minnesota (MN), Mississippi (MS), Missouri (MO), Montana (MT), Nebraska (NE), New Hampshire (NH) (business profits tax), New Jersey (NJ), New Mexico (NM), New York (NY), North Carolina (NC), North Dakota (ND), Ohio (OH), Oklahoma (OK), Pennsylvania (PA), Puerto Rico (PR), Rhode Island (RI), South Carolina (SC), Tennessee (TN) (excise tax only), Utah (UT), Vermont (VT), Virgin Islands (VI),Virginia (VA) (dual residents*), West Virginia (WV), and Wisconsin (WI).

Attach a statement and schedule showing your share of the net income tax paid to the other state.

*A dual resident is any taxpayer who is defined as a California resident under California law and a Virginia resident under Virginia law. If you are a dual resident, you are allowed to claim the other state tax credit for taxes paid to Virginia on Virginia source income. Dual residents who are elected or appointed officials and staff as defined in R&TC Section 17014(b) may claim the other state tax credit for taxes paid to Virginia on all income taxed by Virginia whether or not it has a source in Virginia. See Section H, Income from Sources Within the Other State.

D. California Nonresidents

California nonresident individuals, estates, or trusts that are residents of one of the following states or U.S. possessions and paid a net income tax to that state or U.S. possession on income that is also taxed by California may claim the other state tax credit:

Arizona (AZ), Guam (GU), Oregon (OR), and Virginia (VA).

California nonresidents who are residents of any state or U.S. possession not listed may not claim this credit. This credit is not allowed on a California group nonresident tax return.

E. California Part-Year Residents

California part-year residents:

  • Follow the instructions for residents for the part of the year that you were a California resident.
  • Follow the instructions for nonresidents for the part of the year that you were a nonresident.

F. Dual-Resident Estates and Trusts

An estate or trust may claim a credit if it is treated as a “resident” of California and also as a “resident” of another state. For this purpose an estate or trust is considered a resident of any state that taxes the trust or estate based on its net income. The credit is limited to:

  1. The proportion of the tax paid to the other state by the estate or trust that the double-taxed income bears to the total income taxed by the other state.
  2. The proportion of the estate’s or trust’s California tax that the double-taxed income bears to the total income taxed by California.

Beneficiary of an Estate or Trust

A beneficiary of an estate or trust who is a California resident and pays California tax on income that has been taxed to the estate or trust in another state may also claim the credit. The credit is limited to both of the following:

  1. The proportion of the tax paid to the other state by the estate or trust that income taxed to the beneficiary in California and also to the estate or trust in the other state bears to the total income taxed by the other state.
  2. The proportion of the beneficiary’s California tax that the income taxed to the beneficiary in California and also to the estate or trust in the other state bears to the beneficiary’s total income taxed by California.

Attach a copy of Schedule K-1 (541), Beneficiary’s Share of Income, Deductions, Credits, etc., and a schedule showing your share of the net income tax paid to the other state.

G. Pass-Through Entities

A shareholder of an S corporation is allowed a credit for the shareholder’s share of net and gross income taxes paid by the S corporation to another state that either does not allow S corporation elections or imposes tax on S corporations and the S corporation elected to be treated as an S corporation in the other state. A partner is allowed a credit for the partner’s share of net income taxes paid by the partnership to another state. A member of an LLC classified as a partnership is allowed a credit for the member’s distributive share of net income taxes paid by the LLC to another state.

Attach a copy of Schedule K-1 (100S, 565, or 568), Share of Income, Deductions, Credits, etc., and a schedule showing your share of the net income tax paid to the other state.

H. Income from Sources Within the Other State

Generally residents of California (with the exception of dual-resident estates and trusts) may claim a credit for net income taxes imposed by and paid to another state only on income which has a source within the other state.

For this purpose, California’s sourcing principles apply even though the results may be contrary to the other states’ principles. The following describes the sources of various types of income pursuant to California law:

  • Compensation for services rendered by employees has a source where the services are performed.
  • Compensation for services rendered by independent contractors has a source where the benefit of the services are received.
  • Income from tangible personal property and real estate has a source where the property is located.
  • Income from intangible personal property (such as interest and dividends) generally has a source where the owner resides.
  • Business income has a source where the benefit of the services are received.

Those persons subject to tax as California residents solely by reason of the R&TC Section 17014(b) (holders of federal elective offices, certain Presidential appointees, and Congressional staff members) may base their credit computation on income taxed by the other state, regardless of its source.
