# Form coverage
> The withholding forms Symmetry Payroll Forms supports across the United States and Canada.
SPF supports more than 160 withholding forms across the United States and Canada. This page summarizes what's covered; the [SPF catalog](/spf/references/tax-parameter-catalog-and-schema), published with each release, is the authoritative per-form list along with every form's tax parameter outputs.
## United States
### Federal
The federal W-4 Employee's Withholding Certificate, plus the IRS's official Spanish edition. SPF also supports Form 673, for U.S. citizens claiming exemption on foreign earned income, and Form 8233, for nonresident aliens claiming a treaty exemption.
### State and territory
Every state that levies an income tax has its withholding certificate in SPF, along with the District of Columbia and U.S. territories including Puerto Rico. Beyond each state's primary form, coverage includes:
* **Nonresident and reciprocal certificates** for states that let employees claim exemption under a reciprocal agreement
* **Exemption forms**, including military spouse, Native American, low-income, and no-tax-liability claims
* **Tax adjustment forms**, such as Colorado's DR 1059 Affidavit of Exemption for the Nonresident Spouse of a U.S. Servicemember
* **Spanish editions** where the state publishes one
The nine states with no income tax (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming) have no state withholding forms, and SPF returns none for them.
### Local
Four states have jurisdictions that publish their own withholding forms, and SPF supports all 31 of them:
| State | What's covered |
| ------------ | ---------------------------------------------------------------------------------------------------------------------------------------- |
| Michigan | All 23 city income tax withholding certificates, from Detroit and Grand Rapids to Hudson and Muskegon Heights |
| Pennsylvania | Local Services Tax exemption certificates, including Pittsburgh's, and the CLGS-32-6 residency certification for local earned income tax |
| Oregon | Metro Supportive Housing Services and Multnomah County Preschool for All opt-in/opt-out forms, in English and Spanish |
| Arkansas | The Texarkana withholding exemption certificate |
Many other jurisdictions levy local income tax without publishing their own form. Those jurisdictions collect the employee's election on the state certificate, or apply a flat rate that needs no election at all, so there is no separate local form to complete, and no additional compliance obligation. See [Local withholding forms](/spf/references/local-withholding-forms).
Symmetry audits local jurisdictions annually to confirm every jurisdiction that requires a form with a [perjury statement](/spf/core-concepts/penalty-of-perjury-statements) has one in SPF.
## Canada
### Federal
The TD1 Personal Tax Credits Return, plus TD1X for employees claiming extra amounts at source and T1213 for requests to reduce deductions at source.
### Provincial and territorial
Provincial TD1 forms for every province and territory that uses one: Alberta, British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Northwest Territories, Nova Scotia, Nunavut, Ontario, Prince Edward Island, Saskatchewan, and Yukon.
### Quebec
Quebec uses its own forms rather than a provincial TD1: the TP-1015.3-V Source Deductions Return and the TP-1016 Additional Source Deductions. The federal TD1 still applies in Quebec for federal withholding.
### French editions
Every Canadian form has an official French counterpart. See [Languages and locales](/spf/core-concepts/languages-and-locales).
Canadian coverage differs from the U.S. in a few structural ways beyond the forms themselves: address validation, employer fields, and guided flow structure all work differently. See the [Canadian SPF API overview](/spf/api/canadian-overview).
## Keeping current
Jurisdictions revise forms on their own schedules, and SPF tracks each form's versions independently. A new version takes effect on its published effective date, and API and hosted clients receive it automatically. On-premise clients get it when they deploy the release.
You can preview forms before their effective date to validate a transition ahead of time. See [Form versions and effective dates](/spf/core-concepts/form-versions).
