A significant, genuinely helpful reform to Capital Gains Tax rules for separating couples took effect in April 2023 - giving considerably more breathing room than the old system, which could catch couples out with unexpected tax bills simply because their settlement took longer than a single tax year to finalise.
The old system, and why it was a problem
Married couples and civil partners can transfer assets between themselves on a ‘no gain, no loss’ basis (no immediate CGT charge) while they’re living together - this is about capital assets like property, shares, and investments specifically; everyday cash in a joint account raises different, more immediate practical questions rather than a CGT one. Before April 2023, once a couple separated, this treatment only continued until the end of the tax year in which they separated - meaning a couple separating in, say, March had only a few weeks to transfer assets before facing potential CGT charges on anything transferred afterward, regardless of whether their financial settlement was actually finished.
The current rules, since 6 April 2023
- Until the end of the third tax year after the year of separation (or, if earlier, the date the court grants the final divorce or dissolution order), couples can still make transfers between themselves on a no gain, no loss basis - considerably longer than the old single-tax-year window.
- No time limit at all applies to transfers made under a formal divorce or separation agreement or court order (such as a financial consent order or court order made within financial remedy proceedings, see our dedicated article on consent orders) - meaning couples with a properly formalised settlement don’t face a CGT deadline pressure at all, however long the process takes.
What ‘no gain, no loss’ actually means in practice
This doesn’t make an asset permanently CGT-free - it defers the tax, rather than eliminating it. The receiving spouse takes on the asset at its original acquisition cost, meaning if they later sell it for a profit, they pay CGT based on the gain since the original purchase (not just since the transfer) - the tax is deferred, not avoided.
The matrimonial home: Private Residence Relief nuances
If a spouse moves out of the family home and it’s later sold, or their share transferred, specific rules apply: they can generally treat the period after moving out as still qualifying for Private Residence Relief, provided the home remains their ex-partner’s main residence, they haven’t nominated another property as their main home, and the sale or transfer is made under a formal divorce or separation agreement or court order, and if they retain a right to a share of eventual sale proceeds, that share can, in certain structured situations, retain similar tax treatment to what would have applied had they sold their interest immediately (see our dedicated article on the matrimonial home for the practical options this connects to).
Why ‘connected parties’ status still matters
Once permanently separated, spouses are treated as ‘connected parties’ for CGT purposes until the Final Order (Decree Absolute) - meaning any transfer between them outside the no gain/no loss window is deemed to happen at market value for tax purposes, regardless of what price (if any) was actually paid, which can create a CGT liability on a transfer where no money actually changed hands.
Why professional tax advice should be part of the divorce process, not an afterthought
Especially for settlements involving property beyond the main home, business interests (see our dedicated article on divorcing a business owner), or significant investment portfolios, getting specialist tax advice alongside family law advice - rather than treating CGT as a detail to sort out after the settlement is agreed - can materially affect the actual value each party receives from an apparently equal-looking settlement.
The bottom line
The 2023 reforms gave separating couples considerably more time and flexibility to transfer assets without triggering an immediate CGT bill - up to three tax years generally, and unlimited time if transfers are made under a formal divorce agreement or court order. This removes much of the old time pressure, but doesn’t eliminate CGT altogether, making early tax advice a genuinely valuable part of reaching a fair, fully-understood settlement.
