Married Filing Separately in Texas: Form 8958 and Splitting Community Income

A spouse with an IRS problem often hears the same advice: stop filing jointly. File separately and you are not on the hook for each other's taxes. In most states that works reasonably well. In Texas, it works differently, because filing separately does not make your income separate.

Under Texas community property law, income earned by either spouse during the marriage is generally community income owned half by each. So on separate federal returns, each Texas spouse generally reports half of the community income plus all of their own separate income. Form 8958 is how you show the IRS the math.

Filing separately can still be the right move. You just need to know what it does and does not accomplish.

What Form 8958 does

Form 8958, Allocation of Tax Amounts Between Certain Individuals in Community Property States, is attached to each spouse's separate return. It lists each income item, deduction, and credit, and shows how much belongs on each return. Wages, self-employment income, interest, dividends, rents, capital gains, and withholding all get allocated.

IRS Publication 555, Community Property, is the companion guide. It explains which items are community and which are separate, and how Texas rules differ from other community property states. In Texas, for example, income from separate property, such as interest on an inherited account, is generally community income. That is not true in every community property state, and it surprises Texans who assume inherited money produces separate income.

When the two separate returns are prepared consistently, the totals on both Forms 8958 add up to the household's actual income. When they are not, the IRS's matching programs notice the gap.

Withholding and estimated payments follow the income

Here is the part most people miss. Federal income tax withheld from community wages is itself split between the spouses. Pub. 555 explains that withholding on community wages is divided in the same proportion as the wages. If a husband's paycheck had $10,000 withheld and his wages are community income, each spouse generally claims $5,000 of that withholding on their separate return.

Estimated tax payments work differently. If you made joint estimated payments and then file separately, IRS Publication 505 lets you divide them any way the two of you agree. If you cannot agree, they are divided in proportion to each spouse's tax as shown on the separate returns. That last rule matters when the marriage is under strain.

Getting this wrong creates two kinds of trouble. One spouse claims all the withholding and gets a refund the other spouse's return needed. Or the spouse with an IRS balance claims the credits, and the other spouse ends up with a separate balance due. Either way, a notice follows.

When income does not split: the exceptions

IRC 66 contains three exceptions to the community property split, and each matters to a spouse trying to separate from the other's tax problem.

First, IRC 66(a) applies when spouses live apart all year, do not file jointly, at least one has community earned income, and no earned income is transferred between them during the year. In that case, earned income is taxed to the spouse who earned it. That helps separated couples who are not yet divorced.

Second, IRC 66(b) lets the IRS disregard community property law for a spouse who acted as if solely entitled to the income and failed to tell the other spouse about it before the return due date. The secretive spouse gets taxed on all of it.

Third, IRC 66(c) offers relief to a spouse who did not include community income attributable to the other spouse, did not know and had no reason to know of it, and for whom it would be inequitable to include it. It also allows equitable relief. That is the community property cousin of innocent spouse relief, and it is covered in my community property and innocent spouse guide.

Self-employment income is its own rule

Even when business profit is split for income tax, self-employment tax is not. IRC 1402(a)(5) assigns net earnings from self-employment to the spouse carrying on the trade or business. So on separate returns, the Schedule C profit might be split on Form 8958 for income tax, while the operating spouse's Schedule SE carries the full self-employment tax. I explain the details in my guide on self-employment tax and community property.

When filing separately makes sense for a Texas spouse

Filing separately usually costs more in total tax. The married filing separately status has narrower brackets and loses or limits several credits and deductions. So the question is never only "which is cheaper." It is "what am I protecting?"

Filing separately makes sense when:

• One spouse has an existing IRS balance and the other spouse wants future refunds that are not offset to it. Separate returns keep each spouse's overpayment on that spouse's own account.
• One spouse has unfiled years, aggressive positions, or a business with messy books, and the other spouse does not want joint and several liability for the new year's return.
• The spouses are separated and expect to qualify for IRC 66(a) treatment.
• One spouse distrusts what the other is reporting and wants to sign only their own return.

What separate filing does not do in Texas: it does not stop the IRS from collecting one spouse's tax from community property. The collection rules are separate from the reporting rules. My guide on IRS collection against Texas community property explains what the IRS can reach even when the returns are separate.

Filing separately also does not change prior joint years. Joint and several liability on a joint return already filed stays in place unless relief applies.

Practical tips for getting Form 8958 right

• Both spouses should use the same preparer or at least share the full income picture, so the two Forms 8958 match.
• List every W-2, 1099, and K-1 item, and identify which are community and which are separate.
• Split community wages and the withholding on them in the same proportion.
• Keep the self-employment tax on the operating spouse.
• Document separate property income sources, though remember that in Texas, income from separate property is generally community income.
• If you were separated all year, analyze IRC 66(a) before splitting earned income.

Filing separately is a reasonable shield in Texas. It is just not a wall. If one spouse owes the IRS and you are trying to decide how to file this year, the decision deserves numbers before signatures. The firm's tax planning page explains how forward-looking work fits in. Let's talk: 813-229-7100.
