Tax Implications of Divorce for Self-Employed People

The Accounted Business Team·28 February 2026·7 min read

Divorce is difficult enough without worrying about the tax consequences. But if you're self-employed, there are specific tax issues that employed people don't face. Your business is an asset that needs valuing. Transferring property and other assets has CGT implications. Your tax allowances and thresholds change. And your financial records, which are already more complex than an employee's, come under closer scrutiny during settlement negotiations.

This guide covers the key tax implications of divorce for self-employed people in the 2025/26 tax year, so you can plan ahead and avoid unnecessary surprises.

Business Valuation for the Settlement

When you divorce, all marital assets are considered for division. If you're self-employed, your business is likely one of those assets, and both sides need to agree on what it's worth.

How a Sole Trader Business is Valued

A sole trader doesn't have shares to value, but the business still has worth. Typical valuation approaches include:

Asset-based valuation: Adding up the value of equipment, stock, debtors, and cash, then subtracting liabilities. This gives a floor value but ignores the earning potential.
Earnings-based valuation: Taking an average of recent years' profits and applying a multiplier. The multiplier varies by industry and risk but is often between one and three for a small sole trader business.
Goodwill: If the business has a strong reputation, client base, or recurring income, there's goodwill to value. This is often the most contentious element because it's subjective.

Your tax returns and business accounts will be central to this process. Expect your spouse's solicitor to request at least three years of Self Assessment tax returns, bank statements, and detailed accounts. Clean, accurate records make this process faster and less expensive.

Limited Company Considerations

If you trade through a limited company, the shares in that company are the asset being valued. This is often more complex because retained profits, director's loans, pension contributions made through the company, and the value of any property held by the company all factor in.

A forensic accountant is usually instructed (sometimes jointly, sometimes by each side) to value the business. Their report will heavily influence the settlement.

CGT on Asset Transfers Between Spouses

One of the most important tax rules in divorce is the CGT treatment of asset transfers between spouses and civil partners.

The No-Gain, No-Loss Rule

While you're married or in a civil partnership and living together, transfers of assets between you are treated as happening at no gain and no loss for CGT purposes. This means no CGT is triggered, regardless of the asset's market value.

What Happens After Separation

Following changes introduced in April 2023, you now have until the later of:

Three tax years after the tax year in which you separate, or
Any reasonable time set by a court order or formal agreement

to transfer assets between you on a no-gain, no-loss basis. Before April 2023, the window was much shorter, closing at the end of the tax year of separation.

This extended window is particularly important for self-employed people because business assets, investment properties, and shares may take time to divide. You have more breathing room to complete transfers without triggering immediate CGT liabilities.

When CGT Does Apply

If you transfer assets after the no-gain, no-loss window closes, the transfer is treated as a disposal at market value. CGT is calculated on the gain from your original acquisition cost to the market value at the date of transfer.

For example, if you bought a buy-to-let property for £150,000, and it's worth £250,000 when transferred to your ex-spouse after the window has closed, you'd face CGT on a £100,000 gain (less any allowable costs and the annual exemption).

The Family Home

The marital home is usually the biggest asset. If it's your main residence and has always been your main residence, Private Residence Relief should exempt the entire gain from CGT when it's sold or transferred.

However, self-employed people sometimes complicate this by:

Using part of the home exclusively for business: If you've claimed a dedicated room as used exclusively for business and received tax relief on that basis, that portion may not qualify for full Private Residence Relief.
Owning other properties: If you own rental properties and have nominated one of them as your main residence for any period, the family home might not have full relief for the overlapping period.

In most cases, the family home is still largely or fully exempt, but it's worth checking the detail, especially if you've been claiming business use.

Pension Sharing

Pensions are usually the second-largest asset after the family home, and they're included in the divorce settlement. For self-employed people, pension provision varies enormously. You might have a personal pension, a SIPP, several old workplace pensions from previous employment, or very little pension provision at all.

How Pension Sharing Works

A Pension Sharing Order, made by the court, splits a percentage of one person's pension and transfers it to the other. The transfer itself is not a taxable event. No Income Tax or CGT arises on the pension sharing.

However, the ongoing tax implications are important:

The person whose pension is reduced has less annual allowance available for future contributions (though this depends on the scheme rules)
The person receiving the pension share can transfer it into their own pension arrangement
Future contributions by both parties are subject to the normal annual allowance (£60,000 for 2025/26) and tax relief rules

Self-Employed Pension Planning Post-Divorce

If your pension has been shared and reduced, you'll want to rebuild it. Self-employed people can contribute to a personal pension or SIPP and receive tax relief at their marginal rate. This is one area where post-divorce financial planning is critical, especially if you're in your 40s or 50s and have lost a significant chunk of pension provision.

Marriage Allowance Cancellation

If you've been using the Marriage Allowance (which lets one spouse transfer £1,260 of their Personal Allowance to the other), you need to cancel it when you divorce.

The Marriage Allowance continues to apply for the entire tax year in which you separate, but you must cancel it before the start of the next tax year. If you don't cancel, HMRC may continue applying it, which could result in an underpayment for the higher-earning spouse and an unexpected tax bill.

You can cancel the Marriage Allowance through your Personal Tax Account on HMRC's website or by calling HMRC directly.

Notifying HMRC of Your Change in Status

You should tell HMRC when your marital status changes. This affects:

Your tax code (if you have any PAYE income alongside self-employment)
Marriage Allowance (as above)
Child Benefit: If the High Income Child Benefit Charge applies, the person receiving Child Benefit may change, or the income threshold may now be assessed against a single income rather than a couple's
Tax credits or Universal Credit: Your entitlement changes significantly when you become a single-person household

Self Assessment Considerations

Your Self Assessment tax return asks about your marital status. Make sure this is updated for the tax year in which the divorce is finalised. If you were previously filing jointly for any purpose (such as Marriage Allowance), you'll now file entirely independently.

Maintenance Payments

If you pay maintenance to your ex-spouse, these payments are generally not tax-deductible. You can't reduce your taxable self-employment profits by the amount of maintenance you pay.

There is a limited Maintenance Payments Relief available if either you or your ex-spouse was born before 6 April 1935, but this is increasingly rare.

Child maintenance payments are also not tax-deductible for the payer and not taxable for the recipient.

Protecting Your Business Records

During divorce proceedings, your financial records will be examined closely. This is where having clear, well-organised books makes a real difference. If your records are messy, incomplete, or inconsistent, it can lead to adverse inferences about hidden income or undervalued assets, creating problems that go beyond tax.

If you're going through a significant life change and need your finances to be unambiguous, having reliable, automated bookkeeping is invaluable.
