Understanding divorce and taxes in Ohio is important during tax season
Red Flags in Tax Documents During Divorce
At the time I am writing this blog post, we are in the thick of tax season. April 15th has just passed, and many people have been scrambling to finish last minute tax filings. Coincidentally, many divorce attorneys often see a spike in divorce rates in the spring.
According to research by the University of Washington that analyzed data in 2016 reported that divorce filings “consistently peaked in March and August.” There are several factors that could explain this spike, but many experts have theorized that tax season is partially to blame: for practical reasons, many couples postpone divorce proceedings until after Christmas and the New Year, so they can keep taxes for the preceding year simple. Additionally, filing taxes gives people a clearer view of their financial picture and how to move forward in the future.
Divorce or dissolution in Ohio can mean big changes on your taxes. As a divorce attorney with over 40 years of experience, here are some of my insights into how tax returns can affect the divorce and dissolution process:
Why Reviewing Tax Returns Is Critical in Uncovering Financial Infidelity in Divorce Cases
One of the most revealing documents I review is a client’s tax return. While many people think of tax returns as nothing more than annual filings with the IRS, they are often a roadmap of a couple’s financial life. When carefully examined, tax returns can expose financial infidelity, misconduct, and behaviors that often contribute to the breakdown of a marriage.
Why Tax Returns Matter
In many divorce and taxes in Ohio cases, tax returns become one of the most important documents in uncovering financial realities. Tax returns are uniquely valuable because they are signed under penalty of perjury. Unlike informal financial disclosures between spouses, tax filings are intended to be accurate and complete. This makes them an excellent starting point for identifying inconsistencies or red flags.
A properly reviewed tax return can reveal:
- All sources of income – wages, self-employment income, rental income, dividends, and more.
- Business ownership interests – including partnerships, LLCs, or closely held corporations.
- Investment accounts – through reported interest, dividends, and capital gains.
- Retirement contributions – which may indicate undisclosed accounts.
- Foreign accounts or income – sometimes disclosed through additional reporting requirements.
- Carryforwards and losses – which may suggest prior financial activity not previously disclosed.
Is Financial Infidelity?
Financial infidelity occurs when one spouse hides, lies about, or deliberately obscures financial information from the other. This can include undisclosed income, secret accounts, hidden debts, or spending that contradicts agreed-upon financial norms within the marriage. Often, it is not just the existence of these actions, but the concealment itself, that erodes trust and accelerates divorce.
Red Flags That Suggest Financial Misconduct in divorce and taxes in Ohio
When reviewing tax returns in the context of divorce, several warning signs often point to deeper issues:
- Income that does not match lifestyle– If reported income appears too low to support the couple’s standard of living, there may be unreported cash income or undisclosed assets.
- Sudden changes in income patterns– A sharp drop in income during the period leading up to a divorce may signal manipulation or deferral of earnings.
- Unfamiliar business entities or K-1 forms– These can indicate ownership interests that one spouse may not have disclosed.
- Large or unusual deductions– Excessive business expenses or losses can sometimes be used to disguise actual income.
- Interest or dividend income from unknown accounts – Even small amounts can point to accounts the other spouse did not know existed.
How Tax Returns Uncover Financial Infidelity with divorce and taxes in Ohio
In many cases, tax returns serve as the first clue that something is wrong. For example:
- A spouse may discover a previously unknown investment account through dividend income.
- A Schedule C or K-1 may reveal a side business or partnership interest.
- Mortgage interest deductions may point to ownership in undisclosed real estate.
These discoveries often lead to deeper investigation through subpoenas, depositions, and forensic accounting.
Divorce and taxes in Ohio: The Role of Tax Returns in Divorce Litigation and Settlement Negotiations
Beyond uncovering misconduct, tax returns play a central role in determining:
- Income for purposes of spousal and child support
- The identification and valuation of marital assets
- Credibility of the parties
If a spouse has been dishonest financially, it can significantly impact both the legal strategy and the ultimate outcome of the case.
Why This Matters to Clients
For many individuals, the emotional betrayal of financial infidelity can be just as damaging as other forms of misconduct. Understanding the true financial picture is essential not only for achieving a fair legal outcome, but also for providing clarity and closure.
divorce and taxes in Ohio Conclusion
Tax returns are far more than routine paperwork – they are a powerful investigative tool in divorce cases. For attorneys and clients alike, a careful review of these documents can uncover hidden assets, expose financial misconduct, and ultimately shape the trajectory of a case. This is one reason divorce and taxes in Ohio are so closely connected during both litigation and settlement negotiations.
In divorce, knowledge is leverage. And often, that knowledge begins with a tax return.
