Robinhood Options and Shares, Taxed the UK Way.

Option premiums, assignments, share matching and the interest on your cash, worked out from your activity report.

Options disposals from the Robinhood example: two NVIDIA calls expanded, one closed with Buy to Close and one expired, each premium at the HMRC monthly rate.
Portfolio holdings from the Robinhood example: the AMD pool history with 100 shares added on assignment, and the premium adjustment that reduced their cost.
Stock disposals from the Robinhood example: the matching rule cards and the Tesla same-day sale expanded, sale and cost each at the HMRC monthly rate.
Income section from the Robinhood example: the monthly interest rows at the HMRC monthly rate, and the two NVIDIA stock lending payments listed as other income.

FAQ

Which Robinhood UK file do I upload for UK tax?

+

The account activity report as a CSV: Account, then Reports and statements, then Account activity reports, then Generate new report. Start the date range at your first buy, not at 6 April: the cost of the shares you sell comes from your whole buying history (HS284).

Do I pay Capital Gains Tax on Robinhood UK?

+

In a general investment account, yes, once your gains for the tax year go above the £3,000 annual exempt amount. Gains inside a stocks and shares ISA are tax-free.

My account is in pounds. Which exchange rate is used?

+

HMRC’s monthly rate for the month of each trade, not the rate Robinhood converted at. The FXBUY and FXSELL rows are read as your dollar pool and listed as not chargeable: foreign currency is exempt for an individual.

How are Robinhood options taxed in the UK?

+

Each contract series is its own asset. STO is a disposal on the day you write it (CG12312), BTC reduces that gain, OEXP keeps the premium, and on OASGN the premium goes into the share cost or the proceeds (CG12313). A cash-settled index option nets its premium against the OCC cash row.

Is the interest Robinhood pays on my cash taxable?

+

Yes, as savings income against your Personal Savings Allowance, not as a gain. The INT rows are listed month by month in the income section. SLIP, the fee for lending your shares, is other income for SA100 box 17. MINT, the margin interest you paid, is not deductible and is skipped.

Which date counts, Activity Date or Settle Date?

+

Activity Date. For CGT a share is sold on the day you trade it, not the day it settles (TCGA92 s28), so a sale on 5 April belongs to the tax year that ends that day.

Where are the trading fees?

+

Inside the Amount. Robinhood’s report has no fee column: the regulatory fees on an option are already netted into the premium, and that fee-inclusive Amount is the figure the report works from, so nothing is added or counted twice.

Are my dividends shown before or after US tax?

+

Before. The CDIV row is the gross dividend and DTAX the 15% treaty withholding. HMRC taxes the gross and gives credit for the tax paid, so the report pairs the two rows and keeps the withholding for Foreign Tax Credit Relief.

What happens to a stock reward?

+

The RECUK share enters your pool at market value, taken from the paired REUKC cash row, and the reward is miscellaneous income. The NRAT withholding is flagged for you to check rather than credited.

Are stock splits and mergers handled?

+

Not yet. SPL, MRGS and SXCH rows are skipped with a warning, so if you held a stock through one, adjust the pool on the edit page.

Can I combine Robinhood with another broker?

+

Yes. Upload the files from each broker together. Shares of the same company are one pool however many brokers hold them: the CUSIP in your Robinhood rows is turned into the ISIN that IBKR and Schwab report, so a sale is costed against all of them.
