Gift to Spouse CGT Calculator

No. Transfers between spouses and civil partners living together are treated as no-gain/no-loss for CGT. The recipient spouse takes on the original cost basis — no CGT is triggered at the point of transfer.

Under the no-gain/no-loss rule, when you transfer an asset to your spouse, they are deemed to have acquired it at a price that produces neither a gain nor a loss for you. Their base cost is your original cost.

By transferring assets to a lower-rate taxpaying spouse, you can: (1) use their CGT annual allowance (£3,000), (2) benefit from their lower CGT rate (18% vs 24%), and (3) split the gain between two allowances.

Yes. Each spouse has their own £3,000 CGT annual exempt amount (2025/26). By ensuring both allowances are used, couples can shelter £6,000 of gains per year.

Yes. The same rules apply to civil partners as to married couples. The transfer must be between partners who are living together (not separated).

The receiving spouse takes on your original acquisition cost. When they eventually sell, their gain is calculated from your original cost, not the market value at the date of transfer.

Selling an asset and having your spouse buy it back avoids the 30-day same-person rule and allows an effective base-cost reset. However, HMRC scrutinises transactions that appear commercially motivated only by tax avoidance.

No. Gifts between spouses are exempt from inheritance tax regardless of amount. There is no 7-year rule for inter-spouse gifts.

The no-gain/no-loss treatment only applies in the year of separation. After separation (from 6 April), transfers are at market value and CGT applies to any gain.

In most cases, no SDLT if no consideration is exchanged. However, if the receiving spouse assumes a mortgage, SDLT may apply on the outstanding mortgage amount. Legal advice is recommended.

You can transfer shares but they can only be subscribed as new ISA money — not transferred in specie into an ISA. The spouse would need to sell the shares and use cash to subscribe.

For straightforward transfers, HMRC's guidance is clear. For complex assets (properties, business shares, trusts), consult a tax adviser to ensure the planning is effective and properly documented.
