Tax Treatment of Maintenance Payments: What You Can and Cannot Claim

This guidance is for divorced or separated taxpayers who are unsure whether maintenance payments are taxable in the UK.

The tax treatment of maintenance depends on the type of payment, when the arrangement was made, and who is paying or receiving it. Getting this wrong can lead to Self Assessment errors, incorrect tax bills, or HMRC challenges. This page explains how maintenance payments are treated for tax purposes and where caution is needed.

Maintenance Payments Relief: Who Can Claim It and How the Tax Reduction Works

Maintenance Payments Relief reduces Income Tax for those making court-ordered payments to an ex-spouse or civil partner. To qualify, one party must have been born before 6 April 1935. The relief is 10% of payments, up to £428 per year.

To qualify for this relief, all of the following conditions must apply:

  • Either you or your ex-spouse/civil partner must have been born before 6 April 1935.
  • You must be paying maintenance under a court order after the relationship has ended.
  • The payments must be for the maintenance of your ex-spouse or former civil partner, provided they are not remarried or in a new civil partnership, or for children under 21.
  • This relief offers a 10% reduction in the maintenance you pay, up to a maximum of £428 per year (10% of £4,280).

To claim, you must contact HMRC. The process involves providing necessary documentation, such as proof of the court order and payment records.

This benefit is designed to reduce the overall tax burden, helping someone manage their financial responsibilities after a separation.

However, it’s important to note that this tax relief is limited due to the age condition — it only applies if either party was born before 6 April 1935, which significantly restricts its usage.

Risks of Getting the Tax Treatment of Maintenance Payments Wrong

If maintenance payments are reported incorrectly on a tax return, HMRC may treat this as an inaccuracy. This can result in additional tax being due, interest charges, and in some cases penalties where the return is considered careless or incorrect.

We often see issues arise where taxpayers assume all maintenance payments are tax-free, or where historic rules are applied to modern arrangements without checking whether the exemption still applies.

In Practice – Where Maintenance Payments Are Commonly Misunderstood

In practice, we often see divorced or separated individuals assume that maintenance payments never affect their tax position. Problems usually arise where payments fall outside the standard exemption rules, or where taxpayers are unsure whether amounts need to be disclosed on a Self Assessment return. These misunderstandings commonly come to light only after HMRC queries a return.
