FAQ
Which Fidelity file do I upload for UK tax?
+
From Fidelity.com, the History download: Accounts & Trade, then History, then Download, the CSV whose header begins Run Date, Account, Account Number, Action, Symbol. From Fidelity.co.uk, the Transaction history CSV under Transactions & Reports. Start at your first buy, not at 6 April: the cost of what you sell comes from your whole buying history (HS284).
Do I have to say which Fidelity it is?
+
No. A Fidelity.com History file is known by its Run Date and Accrued Interest columns, a Fidelity International file by the Order date, Transaction type and Product Wrapper header on line 7, after its six-line preamble. A portfolio, positions or valuation export has no dealing rows and is refused by name rather than read as an empty year.
Fidelity.com only lets me download about 90 days at a time. Is that a problem?
+
No. Download each range and upload the files together. A row that appears in two files is counted once.
Which exchange rate is used?
+
HMRC’s monthly rate for the month of each trade. A Fidelity.com file is dollars throughout, with no sterling column, so every buy, sale, dividend and interest row is converted from its own month. A Fidelity International file settles in pounds and needs no conversion.
Is a sale dated by Run Date or Settlement Date?
+
Run Date. HMRC dates a disposal by the day the contract is made, not the day it settles (TCGA92 s28), so the Settlement Date column is not read. Fidelity exports newest first; the rows are put back into date order.
Where are the commission and fees?
+
In the amount. Fidelity.com fills Amount ($) net of Commission ($) and Fees ($), so a buy’s cost and a sale’s proceeds are read from that column as they stand; price × quantity is used only when Amount is blank. Fidelity International puts each Dealing Fee on a row of its own: an EQQQ buy of £357.27 against £355.77 of cash out is a £1.50 fee, already inside the buy’s cost; on a sale it comes off the proceeds. A fee that fits no buy or sale that day is named in a warning.
Are dividends shown before or after US tax?
+
As Fidelity lists them. A DIVIDEND RECEIVED row has one amount and no withholding row beside it, so the report shows the dividend as paid, with £0 of foreign tax against it on the SA106. Tax withheld by Fidelity, if any, is on your 1042-S; enter it there for Foreign Tax Credit Relief.
What happens to SPAXX and the core position?
+
INTEREST EARNED on the core money-market fund is savings interest, shown on the foreign pages as interest from overseas savings. A REINVESTMENT row, a dividend swept back into SPAXX, is a purchase of fund units and sets their cost. A fund that pays as DIVIDEND RECEIVED, SGOV for one, is recorded as a dividend; UK rules may treat that income as interest, so review those rows.
I have an ISA and a SIPP at Fidelity International. Are they left out?
+
Yes. In an All Accounts export, rows in an ISA, Junior ISA or SIPP wrapper are skipped, and one warning says how many. Investment Account and Cash Management Account rows are read. A wrapper with any other name is read as taxable and named in a warning with its line number, so nothing is dropped or taxed in silence.
Why is a Fidelity International Sell row not a disposal?
+
Because it was a withdrawal. Fidelity writes Sell against Cash for the cash leg of taking money out. The Investments column, not the transaction type, says whether a row is a fund or the cash balance, and only a fund is a disposal.
Does excess reportable income work for funds held at Fidelity International?
+
Through the ISIN, which the export does not carry. Vanguard funds are placed from their names and their reported income applied; any other fund is named in a warning so you can enter its ISIN and ERI yourself. Interest is reported gross, the figure the return asks for; the Tax On Interest row Fidelity deducts is not carried through, so enter the tax already paid on the savings pages.
Can I combine Fidelity with another broker?
+
Yes. Upload the files together. Fidelity.com rows carry the ticker, so Apple at Fidelity and at Schwab or IBKR is one Section 104 pool and the 30-day rule runs across them. Fidelity International funds are keyed on the ticker Fidelity prints in brackets, VWRL for instance, or on the fund name when there is none; a name never meets another broker’s symbol, and the report says so when that could matter.
