An affiliate's bad debt claim depends on state rules, any election or assignment, and which entity made the sale and took the loss.
Key takeaways
- Check the state's definition of affiliation before choosing a claimant.
- Match each unpaid invoice to the sale, tax payment, and write-off records.
- Find any election or assignment papers before filing.
This post reads four official state sources that address those questions.
Why the claimant matters
Many small businesses do not sell through a single company. One entity may issue the invoices, another may employ the staff who collect payment, and a third may hold the bank account or the receivable. When a customer never pays, a question follows: which company is allowed to claim the loss?
The question matters because a bad debt is more than a bookkeeping entry. If the wrong entity files, the claim may be denied, or the money may come back to a company that never carried the loss. If the right entity never files, the loss goes unclaimed.
This post is written for small-business owners and bookkeepers who bill through a related company. It is general information, not tax advice. State rules change, and a rule's text can be amended, so check the current version before you file anything.
Throughout, "affiliate" means a company related to the seller in some ownership or control sense. Whether a particular company counts as an affiliate is a legal question, and each state answers it in its own words. The four sources below show four different approaches.
Read the word "affiliate" first
Three of the four sources point directly to section 1504 of the Internal Revenue Code, the federal reference for what counts as an affiliated group. The fourth source, from Washington, relies on the federal consolidated return instead.
The table highlights Washington's consolidated filer rule before the detail below.
| State | Source | Who may claim | What to check first |
|---|---|---|---|
| Washington | WAC 458-20-196 | For consolidated federal filers, the seller that made the sale and took the loss | Whether the group files a consolidated federal return |
You do not need to master section 1504 to read these state sources. You do need to know that a state rule using the word "affiliate" may be using a defined federal term. If a state rule borrows that term, the ownership test comes from the federal statute, not from a general sense of who "owns" whom. Read the federal text before you rely on a conclusion that two companies are affiliated.
Ownership alone does not settle the state question either. A state may also ask whether a company made the sale, whether it reported and paid the tax, whether it holds an election, or whether the receivable was assigned to it. Keep those questions separate when you review your own setup.
Ohio defines the affiliated group
The first source is Ohio Revised Code section 5739.121. Its definitions include this sentence:
> "(6) "Affiliated group" has the same meaning as in section 1504 of the Internal Revenue Code."
Source: Ohio Laws and Administrative Rules, "Section 5739.121 - Ohio Revised Code | Ohio Laws"
This sentence does one job. It tells you what "affiliated group" means wherever the phrase appears in the section. It is a definition, not a rule about who may claim a loss. The quoted sentence does not, by itself, say which member of an affiliated group may claim a bad debt, so do not read it as answering that question.
Here is how to use it. Open the full section and search for every place where "affiliated group" appears. Read each of those sentences alongside the definition. Then ask a specific question: does the sentence that gives a bad debt right or limit it refer to the affiliated group, and if so, which member does it name? If the answer is unclear, take the question to a tax adviser who can read the whole section and any related state guidance.
California ties the claim to an election
California's Regulation 1642 is the most detailed of the four sources on this point. Two passages matter for affiliates.
The first passage says that, for purposes of the regulation, "retailer" includes an affiliated entity in certain circumstances:
> "(B) The term "retailer" as used in this regulation (except as used in subdivisions (h) and (i)) includes an entity affiliated with a retailer under section 1504 of Title 26 of the United States Code with respect to those accounts for which the affiliated entity is the person entitled to the bad debt deduction or claim pursuant to an election filed under this subdivision (h)(3)."
Source: California CDTFA, "Regulation 1642"
Read this sentence slowly, because it has three limits built into it. The affiliate is treated as a retailer only for certain accounts, not for all of the seller's accounts. It is treated that way only where the affiliate is the person entitled to the bad debt deduction or claim. And that entitlement must come from an election filed under subdivision (h)(3).
In practice, a California bookkeeper should ask three questions for each account or group of accounts. Was an election filed under the subdivision the regulation names? Which entity is named as the person entitled to the claim? Do the accounts in question match the accounts that election covers? If the answer to any of these is "I don't know," start by finding the filing. Do not assume the affiliate can claim.
The second passage describes who counts as a qualifying person:
> "(C) A person who is either an affiliated corporation (or affiliated entity electing to be taxed as a corporation) under section 1504 of Title 26 of the United States Code or an assignee of a person described in subdivision (i)(1)(A) or (i)(1)(B)."
Source: California CDTFA, "Regulation 1642"
This passage adds two groups. The first is affiliated corporations, and affiliated entities that elect to be taxed as corporations, under section 1504. The second is assignees of certain persons described elsewhere in the regulation. The assignee point matters for businesses that sell or transfer receivables. If a customer account moved from one entity to another, the transfer may change which entity is the qualifying person. Look for the paperwork that shows the transfer, and check it against the regulation's language rather than assuming a transfer is only a bookkeeping event.
Washington limits consolidated filers
The third source is Washington's rule, WAC 458-20-196. It covers two points that matter for affiliates.
The first point concerns taxpayers who do not have to file a federal return:
> "However, if a taxpayer who is not required to file a federal return is otherwise eligible for a federal income tax bad debt deduction, credit, or refund, that taxpayer may claim a Washington bad debt deduction, credit, or refund on a previously paid Washington state tax."
Source: Washington State Legislature, "WAC 458-20-196"
The Washington claim is tied to tax that was previously paid to Washington, so a business that never paid that tax should not expect this provision to produce a refund.
The second point is the consolidated filer rule, and it is the most direct statement among the four sources about which affiliate may claim:
> "For taxpayers who file a consolidated federal return with controlled affiliates, the bad debt deduction, credit or refund is only available to the original seller or provider that incurred the loss from the worthless debt."
Source: Washington State Legislature, "WAC 458-20-196"
The practical test is historical. For each unpaid invoice, find the entity that made the sale or provided the service, and the entity that took the loss when the customer did not pay. Be careful about its limits. The sentence addresses consolidated federal filers only. If your group does not file a consolidated federal return, it does not answer your question, and you should read the rest of the rule before drawing a conclusion.
Florida reaches entities that are not corporations
The fourth source is Florida law in Chapter 212, section 17 of the Florida Statutes. It uses the same federal reference as Ohio and California, but its language reaches further. Three excerpts are relevant. They are fragments of longer sentences, so read them in context:
> "1504 or an entity that would be an affiliate under that section if the entity were a corporation."
> "Is affiliated in the manner described under 26 U.S.C. s."
> "1504, regardless of whether the different entities are corporations, with a person described in sub-subparagraph a. or sub-subparagraph b. or with an assignee or other transferee of such person."
Source: The Florida Senate, "Chapter 212 Section 17 - 2025 Florida Statutes"
Open the full paragraph at the link and read every clause around each excerpt. For a business organized as a limited liability company or a partnership, the corporate form alone will not settle the affiliation question.
If an entity received a customer account by assignment or transfer, read the Florida language to see whether that entity falls within the category the statute describes. Do not assume a transferee has the same rights as the original seller without checking.
A business organized as something other than a corporation should not conclude that the affiliate rules are irrelevant to it. Check how each of your entities is organized before ruling anything out.
A checklist for your own invoices
Reading four state sources is easier with a checklist that matches your own records. Each answer should point to a record, not a memory.
- Which entity issued the invoice? Use the name on the invoice and the entity that holds the sales record, and note any difference.
- Which entity reported the sale on its tax return? A company that issued the invoice may not be the company that reported the sale, so check the two separately.
- Which entity paid the tax on the sale? Keep the payment record and the period it covers.
- Which entity wrote off the debt in its books? The write-off entry is the record of who took the loss.
- Is each entity affiliated with the others under the test the state uses? For Ohio, California, and Florida, start with section 1504. For Washington, check whether the group files a consolidated federal return.
- Was there an election, an assignment, or a transfer? For California, look for an election under subdivision (h)(3). For Florida, look for an assignee or other transferee. Note the date and the accounts it covers.
- Which state applies to each sale? A multistate group may have different answers in each state, so do not carry one state's answer into another.
- What documents support each answer? Keep the invoices, the collection attempts, the write-off entries, and any election or assignment papers together.
This checklist does not replace reading the rules. It shows whether you have the facts the rules ask about. If you cannot answer a question from your records, that gap is a finding in itself, and it should be resolved before any claim is filed.
For help organizing the supporting files, see electronic invoice record checks and reconciling invoice payments with your bank.
Illustrative example: follow the unpaid balance
The seller issued the invoice, while a related company handled collection. Start with the invoice and payment record, then find the write-off entry. Record which entity made the sale and which took the loss. Do not choose the claimant merely because the collection company handled the account. Match those records to the applicable state rule and any election or assignment papers.
Common mistakes to avoid
The first mistake is treating common ownership as the whole test. Check the definition the state uses, not the org chart.
The second mistake is filing the claim from whichever entity holds the receivable on the books. Holding a receivable and taking a loss are not always the same thing, so confirm which entity actually made the sale.
The third mistake is missing an election or an assignment. Searching only the invoices can miss these papers, so check the corporate and filing files too.
The fourth mistake is assuming one answer applies everywhere. A group that sells in several states needs an answer for each state.
The fifth mistake is relying on an old copy of a rule. Print the text with its date, and check the official site again before you file.

Questions to take to a tax adviser
Which entity in our group made each sale?
Start with the entity named in the sales record and compare it with the invoice. Bring both records if they name different companies, along with evidence of which entity paid the tax and wrote off the debt.
Did we file any election or assignment that changes the claimant?
Check the filing and transfer papers for the accounts in question. Bring copies so your adviser can compare the named entity and covered accounts with the applicable state language.
Do we file a consolidated federal return?
Check the group's federal return before applying Washington's consolidated filer provision. If you use an outside billing or collection company, ask whether that company is an assignee or transferee under the state language. Bring copies of the relevant sources, with the links and the date you printed them.
