Divorce and Taxes

Filing status: the year-end rule and head of household qualification

Your filing status for the entire tax year is determined by your marital status on 31 December of that year. If your divorce is finalised on 30 December, you are considered unmarried for the entire year and must file as single or head of household. If the divorce is not finalised until 2 January, you are considered married for the prior year and must file as married filing jointly or married filing separately. This bright-line rule under IRC Section 7703(a)(1) can create significant planning opportunities — or traps — depending on the timing of your divorce finalisation.

Head of household filing status is available to an unmarried taxpayer who maintained a home that was the principal residence of a qualifying child for more than half the year and who paid more than half the cost of maintaining that home. The head of household brackets are wider than single brackets and the standard deduction is higher ($24,200 vs $16,100 for 2026 estimated). A taxpayer who is legally married but lived apart from their spouse for the last 6 months of the year can also qualify as head of household under the "considered unmarried" rule of IRC Section 7703(b) if they maintained a home for a qualifying child and paid more than half the household costs.

For the year of divorce, if you were still married on 31 December of the prior year and filed jointly, any joint liability for that prior year remains joint. Under IRC Section 6013(d)(3), both spouses are jointly and severally liable for the tax, penalties, and interest on a joint return. A divorce decree that assigns responsibility for prior-year taxes to one spouse does not bind the IRS — the IRS can and will collect from either spouse regardless of the divorce agreement. Innocent spouse relief under Section 6015 may be available if your former spouse understated tax on a joint return without your knowledge.

Your filing status is based on your marital status on December 31. Head of household requires maintaining a home for a qualifying child and paying more than half the household costs. (IRC §7703(a)(1); IRC §7703(b); IRC §6013(d)(3); IRC §6015)

Property transfers between spouses: the Section 1041 non-recognition rule

IRC Section 1041 provides that no gain or loss is recognised on transfers of property between spouses, or between former spouses if the transfer is incident to the divorce. A transfer is "incident to the divorce" if it occurs within one year after the date the marriage ceases, or if it is related to the cessation of the marriage (which the regulations presume if the transfer occurs within 6 years and is pursuant to the divorce decree or a written agreement). This is a mandatory non-recognition provision — it applies regardless of the fair market value of the property transferred.

The transferee spouse takes the property with the transferor's adjusted basis (carryover basis) under Section 1041(b)(2). This is critically important for appreciated assets. If one spouse receives a $500,000 business that the other spouse built with a $50,000 basis, the receiving spouse takes a $50,000 basis. When they eventually sell the business, they will recognise $450,000 of gain. In contrast, if they had received $500,000 in cash (which has a basis equal to its face value), there would be no future gain. The tax burden in the carryover basis makes the appreciated asset less valuable than its fair market value in a divorce settlement. Competent divorce attorneys and CPAs calculate the "after-tax value" of each asset to ensure equitable division.

Section 1041 applies to all property — business interests, real estate, investment accounts, vehicles, even cryptocurrency. It does not apply to transfers to third parties, transfers after the 6-year window (unless pursuant to the decree), or transfers between unmarried cohabitants who were never married. For self-employed individuals, the transfer of a business interest or business assets between spouses is tax-free under Section 1041, but the receiving spouse inherits the tax history of those assets, including depreciation recapture potential under Sections 1245 and 1250.

Property transfers between spouses (or former spouses incident to divorce) are tax-free. The receiving spouse takes the transferor's basis, which means they inherit the future tax liability on any built-in gain. (IRC §1041; IRC §1041(b)(2); Treas. Reg. §1.1041-1T)

Alimony, child support, and the TCJA permanent rule change

The tax treatment of alimony underwent a permanent change under the Tax Cuts and Jobs Act. For divorce or separation agreements executed after 31 December 2018, alimony payments are not deductible by the payor and are not included in the recipient's gross income. This rule is codified in IRC Section 71 (repealed for post-2018 agreements) and Section 215 (deduction repealed for post-2018 agreements). The change is permanent — OBBBA did not restore the prior treatment.

For divorce agreements executed before 1 January 2019, the old rules still apply: alimony is deductible by the payor (above-the-line, reducing AGI) and includible in the recipient's income. However, if a pre-2019 agreement is modified after 2018 and the modification expressly provides that the TCJA change applies, the new (non-deductible/non-taxable) treatment kicks in. This matters for renegotiations — a modification that does not specifically adopt the new rules preserves the old treatment.

Child support has never been deductible by the payor or taxable to the recipient, and this remains unchanged. The distinction between alimony and child support is critical. Under IRC Section 71(c) (still applicable for defining the boundary), payments that are designated as child support, or that are reduced upon a contingency related to a child (such as the child reaching age 18 or moving out), are treated as child support regardless of how they are labelled in the agreement. The IRS looks at substance over form.

For self-employed individuals, the payor's SE income is a primary factor in calculating both alimony and child support. Courts typically use Schedule C net profit (sometimes with addbacks for discretionary expenses, depreciation, and owner benefits) to determine income available for support. This is where business valuation and income analysis intersect with family law — and where a self-employed individual's tax planning during the marriage can affect support calculations during the divorce.

For divorce agreements executed after 2018, alimony is not deductible by the payor and not taxable to the recipient. Pre-2019 agreements retain the old deductible/taxable treatment unless modified to adopt the new rules. (IRC §71 (repealed for post-2018); IRC §215 (repealed for post-2018); TCJA §11051; IRC §71(c))

Child-related credits, retirement account QDROs, and community property complications

The allocation of child-related tax credits between divorced parents follows specific rules. Under IRC Section 152(e), the custodial parent (the parent with whom the child lives for the greater number of nights during the year) claims the child as a dependent and is entitled to the Child Tax Credit ($2,200 for 2026 under OBBBA), the Child and Dependent Care Credit, the Earned Income Tax Credit, and the head of household filing status. The non-custodial parent can claim the CTC only if the custodial parent signs Form 8332 (Release/Revocation of Release of Claim to Exemption for Child by Custodial Parent), releasing the dependency exemption for one or more years. Form 8332 releases only the CTC — it does not transfer the CDCC, EITC, or head of household status, which always belong to the custodial parent.

Retirement accounts are divided in divorce through a Qualified Domestic Relations Order (QDRO) under IRC Section 414(p). A QDRO is a court order that directs the retirement plan administrator to pay a specified portion of one spouse's retirement benefits to the other spouse (the "alternate payee"). The critical tax advantage of a QDRO is that the transfer itself is not a taxable event and is not subject to the 10% early withdrawal penalty under Section 72(t), even if the alternate payee is under age 59 and a half. The alternate payee can roll the QDRO distribution into their own IRA or qualified plan tax-free, or they can take a cash distribution (which is taxable as ordinary income but still exempt from the 10% penalty). QDROs apply to 401(k)s, pensions, and other employer-sponsored plans. IRAs do not use QDROs — IRA transfers incident to divorce are governed by Section 408(d)(6) and are tax-free if transferred directly between the spouses' IRAs.

Community property states (Arizona, California, Idaho, Louisiana, New Mexico, Nevada, Texas, Washington, and Wisconsin) add complexity. In these states, income earned during the marriage is community property, meaning each spouse owns half regardless of who earned it. For married filing separately returns in community property states, each spouse must report half of the total community income. For self-employed individuals, this means half of your Schedule C net profit may be reportable by your spouse on their separate return if you file MFS during the year of separation. Upon divorce, community property is divided — but the Section 1041 non-recognition rule still applies, so the division itself is tax-free.

The custodial parent claims child credits unless Form 8332 is signed. QDROs split retirement accounts without tax or early withdrawal penalties. Community property states require splitting community income 50/50 on MFS returns. (IRC §152(e); IRC §414(p); IRC §72(t)(2)(C); IRC §408(d)(6); IRC §66)
