Do nonresident withholding exemption certificates expire, who keeps them, and why will a tax-exempt partner not sign one?

Why the lifecycle is the question

A nonresident withholding exemption is a document that moves the state's collection risk from the partnership to the partner. The partner certifies a fact (residence, a place of business, a filing commitment, exempt status), and the partnership stops withholding on the strength of it. The state's interest is that someone pays; the partnership's interest is that the document still says something true on the day the partnership relies on it.

The variables that differ from state to state are four: who signs (the partner, or the state on the partner's request), who keeps the document (the partnership, the state, or both), whether it goes to the state with the return, and what ends it (a printed date, a year, a change of facts, revocation by the state). A certificate that was valid when signed protects the partnership only for as long as its own terms and the state's rule allow. A file assembled once and never revisited drifts out of date in two directions: it keeps documents that have lapsed, and it lacks documents that a new partner or a new year requires.

The setting used below is invented. An investment partnership holds operating companies and leveraged real estate through lower-tier entities and files returns in California, Georgia, New York, Pennsylvania, Alabama, Utah and Illinois. Its partners are a pension trust qualified under IRC section 401(a) (the pension trust), a C corporation with no place of business in any of those states, and several nonresident individuals.

Seven states, seven lifecycles

California. California has two instruments with opposite lifecycles. Form 590, the withholding exemption certificate, is signed by the payee and kept by the withholding agent; the 2025 instructions state that the certification "does not need to be renewed annually" and "remains valid until the payee's status changes." The agent is relieved of withholding if it "relies in good faith on a completed and signed Form 590," unless notified by the Franchise Tax Board that the form should not be relied upon, and "An incomplete certificate is invalid." The agent keeps the certificate "for at least five years after the last payment to which the certification applies" and provides it to the FTB on request. The form carries a box for a tax-exempt entity (identified by its IRC section 501(c) or Rev. and Tax. Code section 23701 status) and a separate box for "a federally qualified pension or profit-sharing plan," and it asks no question about UBTI. Form 588, the nonresident withholding waiver request, is the opposite: the FTB grants it, and the agent may stop withholding only after it has received the FTB's Waiver Determination Notice. The 2025 instructions state that a waiver is effective "for a maximum term of 24 months and will expire on December 31 of the succeeding calendar year" in which it was granted, and they advise filing the request at least 21 business days before the payment. The library's California withholding articles cover the regime itself; for lifecycle purposes, the certificate lasts until a fact changes, and the waiver lasts until a date.

Georgia. Georgia's Form NRW-Exemption (REV 7/13) collects five different certifications on one affidavit, each with its own lifecycle. A C corporation, individual or fiduciary member certifies "On a one time basis and on or before the due date (without extension) for filing the entity's income tax return" for the first year withholding would otherwise apply (Ga. Comp. R. & Regs. 560-7-8-.34(2)(g)1), and if the member later fails the conditions, "withholding will be due as originally required as if such certification had not been made" (rule 560-7-8-.34(2)(g)2). Individual retirement accounts, Roth IRAs and qualified employer plans as defined by IRC section 409A(d)(2), which include a trust forming part of a plan described in IRC section 401(a), are not subject to withholding on a one-time certification, with no UBTI condition (rule 560-7-8-.34(2)(b)). An exempt organization, by contrast, "shall annually certify in writing to the entity using Form NRW-Exemption" (rule 560-7-8-.34(2)(e)), and the form's own heading for that item reads "(note must be made annually)." Every certification, one-time or annual, is attached to the entity's return each year. No withholding is required for a member whose aggregate annual share of Georgia income is less than $1,000 (rule 560-7-8-.34(2)(c)). The withholding regime is O.C.G.A. section 48-7-129.

New York. New York's estimated tax paid by a partnership on behalf of partners reaches partners that are nonresident individuals or C corporations (Tax Law section 658(c)(4)(A)); the paragraph does not list estates or trusts. Section 658(c)(4)(D) excuses a partner whose required estimated tax is $300 or less and authorizes the Commissioner to waive the requirement. The waiver instruments are Form IT-2658-E for nonresident individuals and Form CT-2658-E for corporations. Both are kept by the partnership and not sent to the Department, and both carry a printed expiry: "Form IT-2658-E (12/25) expires on February 1, 2028," and the corporate certificate states the same date. For the individual form the instructions add: "If you are exempt from estimated tax payments after that date, you must provide a new Certificate of Exemption." A New York certificate is therefore a dated document, and it also ends with a change of facts: an individual partner must notify the partnership within 10 days after it no longer expects to meet the certificate's conditions, and a corporation within 10 days after it no longer meets them (Form IT-2658-E and Form CT-2658-E instructions).

Pennsylvania. The Department of Revenue's Personal Income Tax Guide describes withholding by a partnership on each nonresident owner's expected share of Pennsylvania-source income, where the owners are "nonresident individuals, nonresident estates, or nonresident trusts," and it states that an entity "may not withhold Pennsylvania personal income tax for another entity." The guide describes no exemption certificate for these owners. The Pennsylvania entry in the register is therefore a classification entry, not a document: which partners are individuals, estates or trusts, and which are entities outside the regime. The guide's chapter on estates and trusts states that a trust for Pennsylvania personal income tax purposes does not include a pension trust or profit-sharing trust, so the pension trust falls outside the owners for whom the guide describes withholding.

Alabama. Alabama's instrument is a composite payment rather than withholding, required by Ala. Code section 40-18-24.2 at the 5 percent maximum rate under section 40-18-5. The Department's 2025 Form PTE-C instructions list among exempt nonresident owners exempt organizations whose share of Alabama-sourced taxable income does not produce UBTI, and state that the payment for an owner exempt from Alabama income tax under section 40-18-32 is zero unless the income is unrelated business taxable income under 26 U.S.C. section 512. The owner certifies on Schedule NRC-Exempt, which must be attached to Form PTE-C each year; without it, the entity remits the payment as originally required. The lifecycle is one return.

Utah. Utah has no exemption certificate for exempt owners. A pass-through entity "is not required to withhold a tax on behalf of a pass-through entity taxpayer" that is exempt from taxation under Utah Code section 59-7-102 where "the income from the pass-through entity is not unrelated business income to the pass-through entity taxpayer" (Utah Admin. Code R865-9I-13(5)(a)(i)). The entity applies the condition itself. Utah's other instrument is a waiver box on the return: under R865-9I-13(6), the entity applies for a waiver of penalty or interest on an amount it failed to withhold, for a taxpayer that "files and pays in a timely manner," by checking the box on the return requesting the waiver. The waiver is claimed after the year and depends on what the partner did, so it has no lifecycle beyond the return on which it is claimed.

Illinois. Illinois's regulation excludes from pass-through withholding an owner "who is exempt from taxation under IRC section 501(a)" or under section 205 of the Illinois Income Tax Act, an owner included on a composite return, and a non-individual owner for which the entity holds a valid certificate of exemption on the withholding due date (86 Ill. Adm. Code 100.7035(g)(1)). A certificate is valid if it "is completed using the form prescribed by the Department" and "has not been revoked" (section 100.7035(h)(1)), and it is retained by the entity (section 100.7035(h)(2)). The Department may revoke a certificate by notice when the owner fails to file or pay, and the revocation is effective for withholding due "more than 60 days" after the notice; neither the owner nor the entity may protest it (section 100.7035(h)(3)). The Department's Publication 129 (R-12/25) names Form IL-1000-E as the certificate for "any member that is not an individual," states that it is not sent to the Department unless requested, and states that "Any Form IL-1000-E on file can be ignored" when the entity elects the pass-through entity tax.

What ends an instrument

Across the seven states, five events end or defeat an instrument, and each needs its own entry in the register.

A printed date. New York's certificates lapse on February 1, 2028, and California's Form 588 waiver lapses on December 31 of the year after the grant. Nothing the partner does extends them; a new instrument is required.

A year. Georgia's exempt organization certification and Alabama's Schedule NRC-Exempt are annual. A certificate on file from the prior year does not cover the current one.

A change of facts. California's Form 590 lasts until the payee's status changes, and the payee undertakes to notify the agent if the entity "ceases to be exempt from tax." Georgia's one-time corporate certification fails for any year in which the member does not meet the conditions. These instruments have no expiry date, so the event that ends them is visible only through the partner.

Revocation by the state. Illinois may revoke a certificate by notice, and California's good-faith reliance ends when the FTB notifies the agent that a Form 590 should not be relied upon. The register records the notice and the date from which withholding resumes.

A different partner. Each instrument read is a certification by the named member, signed by that member or its authorized signer. None of the forms provides for a certificate to pass to a successor. A certificate signed in a predecessor's name after a merger, conversion or transfer of the interest is not a certification by the current partner, and the sound course is a new certificate in the current partner's legal name before the next payment date. The same reasoning applies to a certificate signed by a disregarded entity rather than its owner, where the state looks to the owner.

Why a tax-exempt trust will not sign

The objection is specific, and for an exempt organization that is not a retirement account or qualified plan it is well founded in two of the seven states. Georgia's exempt organization item asks the member to certify "that its share of the taxable income sourced to this state (for which this exemption is claimed) does not result in unrelated business taxable income," and the rule makes the consequence explicit: a share that "results in unrelated business taxable income, as defined by Internal Revenue Code § 512, will be subject to withholding," while a share that does not is not (rule 560-7-8-.34(2)(e)). Alabama conditions its exempt organization category on the same fact. The certification is attached to each return in Alabama, and is annual in Georgia for an exempt organization outside the retirement items, so the partner is asked each year to represent a fact about that year's income.

Whether a partner's share is UBTI turns on the partnership's activities and debt, which the partner learns from the partnership. Under IRC section 512(c)(1), an exempt organization that is a partner includes in UBTI its share of the gross income of a trade or business regularly carried on by the partnership that is unrelated to the organization, with the connected deductions, whether or not the income is distributed. Under section 512(b)(4), income from debt-financed property is included under the rules of section 514. A partnership that runs an operating business or holds leveraged real estate through lower tiers can produce UBTI for an exempt partner, and the amount is known with confidence only when the partnership's own lower-tier information arrives. An exempt organization's position, that it cannot certify the absence of UBTI before it sees a K-1, describes the sequence accurately: the Georgia certification is made annually and attached to the entity's return, Georgia's withheld tax is due by the return's due date without regard to extension (rule 560-7-8-.34(6)(b)1), and the K-1 that would answer the question can arrive after that date.

The objection does not arise everywhere. Illinois excludes a section 501(a) owner by regulation, so the pension trust needs no IL-1000-E. Utah applies the UBTI condition through the entity's own determination and requires no signature. New York's estimated payment requirement reaches nonresident individuals and C corporations, so a trust partner is outside it. California's Form 590 asks for exempt status, not a UBTI representation. Georgia's retirement account item asks the pension trust for no UBTI representation, so for the pension trust the problem is confined to Alabama.

Where the representation is required, three courses are open on the forms. The partnership can supply the trust with its own early estimate of the items that produce UBTI (operating business income from lower tiers, debt-financed income) so that the trust can certify on information rather than on assumption. The trust can decline, in which case the state's default applies and the amount is withheld or paid on its share. Or, in Georgia, a share below the $1,000 threshold needs no certification at all. None of the forms permits a conditional certification, and a certification given without a basis is a statement under penalty of perjury on the Georgia form.

The register

The working tool is a table with one row per partner per state. Each row holds the partner's legal name and federal classification, the state, the instrument (or "none required," with the rule that makes it so), the date signed, who keeps it, whether it goes with the return, the expiry or renewal trigger (a date, each year, a change of facts, revocation), and the next action date. For the invented partnership, the pension trust's rows read in substance as follows: California, Form 590 in the qualified plan box, kept by the partnership, valid until status changes; Georgia, a one-time NRW-Exemption retirement account certification, attached to each year's return; New York, none (the trust is outside section 658(c)(4)(A)); Pennsylvania, none, since the guide excludes a pension trust from the definition of a trust; Alabama, annual NRC-Exempt, conditioned on no UBTI; Utah, none, with the entity's UBTI determination documented; Illinois, none, under the section 501(a) exclusion.

The C corporation's rows look different: a one-time Georgia certification attached each year, a CT-2658-E with a 2028 renewal date, an IL-1000-E valid until revoked, and in California either a Form 590 (if it qualifies) or a Form 588 waiver with a December 31 end date. The nonresident individuals' rows carry IT-2658-E certificates with the same 2028 date and Pennsylvania withholding entries. A partner admitted, merged or converted during the year starts a new set of rows.

Practice notes

The register is reviewed at three points each year: before the first estimated or withholding payment date, before the unextended return due date (when Georgia's one-time certifications and the annual exempt organization certifications are due with or before the return), and before the extended return is filed. Each instrument is matched to the partner's current legal name and federal classification, and a disregarded partner is documented at the owner level. Dated instruments are calendared for renewal ahead of their expiry, and annual ones are requested with the partnership's preliminary estimates rather than with the K-1. For an exempt partner asked for the UBTI representation, the request goes out with the partnership's own estimate of operating business and debt-financed income from its lower tiers, so the partner can certify on information or decline in time for the partnership to withhold. A state notice revoking or disregarding an instrument is entered in the register the day it arrives, with the date from which withholding resumes. G&G State Tax Group provides nonresident withholding exemption reviews and partner documentation registers for partnerships with tax-exempt, corporate and individual partners alongside its state and local tax practice.
