Moving a brokerage account means the new firm pulls your holdings from the old one, and done in kind nothing is sold. In the US most moves run through ACATS, the clearing system’s automated transfer service, on a timetable set by FINRA Rule 11870.

The part that costs money is not the paperwork. It is the choice between moving the shares and selling them to move cash.

This page walks through the seven steps, the rule’s deadlines, what to do with holdings that will not transfer, and two numbers worth seeing before you sign: what a sell-and-rebuy transfer would have realized on a real ten-year SPY position, and how far the market moves in the few days a transfer takes.

Before you start

A list of every holding, because some of them may not be transferable. Funds run by your current firm, positions the new firm does not carry, and fractional shares are the usual problems. Write down the share count and purchase cost of each line while you can still see it.

Written confirmation that the transfer is in kind rather than a sale. Ask the new firm to state it on the request. In a taxable account that one word decides whether the move is paperwork or a tax event.

The exit fee from the old provider and any incoming fee at the new one. The old firm’s fee schedule lists it. Ask the new firm whether it covers that fee before you send anything, not after.

Have your latest statement to hand too. The account title, number and type on the request must match the old account exactly, because a mismatch is a common reason a request is sent back.

The steps

1. Open the new account in the same name and type

A taxable account moves to a taxable account, an IRA to an IRA, a Roth IRA to a Roth IRA. A joint account needs the same owners. Matching the type is what lets the shares move without being sold or treated as a distribution.

2. Submit the transfer request at the new firm

The receiving broker enters the request in ACATS and the old firm responds. Under Rule 11870(b)(1) the old firm then has one business day to validate the instruction or take an exception, for example a name or account number that does not match.

3. Mark the request in kind and list the positions

Choose a full transfer to move everything, or a partial one that names the positions and share counts. A partial transfer leaves the old account open with whatever stays behind.

4. Stop trading once the request is validated

When a full transfer is validated, Rule 11870(d)(1) has the old firm cancel open orders (options expiring within seven business days aside) and take no new ones. You still own the shares and they still rise and fall; you just cannot sell them until they arrive.

5. Decide what happens to holdings that cannot move

The rule calls these nontransferable assets: the old firm’s own products the new firm will not accept, and third-party products the new firm does not carry.

The old firm must list them and ask for your instructions in writing. Once you answer, it has five business days to send the sale proceeds or start the transfer (Rule 11870(c)(5)).

6. Check every position and its cost basis on arrival

Compare the new account line by line against your list. Rule 11870(e) gives the old firm three business days after validation to complete the transfer. Then open each position and confirm a purchase cost and date came with it.

7. Watch the old account for stragglers, then close it

Dividends and interest can land after the move. For at least six months after a full transfer, Rule 11870(n)(2) has these residual credits sent on within 10 business days of reaching the old account. Close the old account once nothing is left in it.

How to tell it worked

Every transferable line arrived, with the same share count you wrote down, within about 4 business days of the request being validated.

0 positions were sold. The new account’s history shows a transfer in, with no sales and no cash standing in for a holding you meant to keep.

Each position shows a purchase date and cost. Check all of them within 5 days of arrival, while the old firm’s statements are still easy to download.

The old account shows a zero balance, or is open for a reason you can name, such as a fund that could not move.

What selling to move would cost: a real example

Take 100 shares of SPY, an S&P 500 fund, bought at the close on 4 January 2016 for $201.02 each. That is $20,102. At the close on 30 October 2026 the same shares were worth $755.72 each, or $75,572 (Yahoo Finance closes, dividends left out).

Moved in kind, nothing happens for tax purposes. The shares, their cost and their purchase date arrive together, and the $55,470 of growth stays unrealized.

Sold so cash can move instead, the $55,470 becomes a realized gain. The shares were held for more than a year, so it is a long-term gain.

The IRS says the rate on most net capital gain is no higher than 15% for most individuals (Topic 409, read 1 Nov 2026); if the whole gain falls in the 15% band, that is $8,320.50 of federal tax, before any state tax.

For 2025 the IRS puts a single filer in the 15% bracket on taxable income above $48,350 up to $533,400.

A transfer fee of the size the top-ranking guides quote, around $50 to $100, is a rounding error next to that. Which is why the in-kind instruction matters more than which firm pays the fee.

The original data

Selling and rebuying also leaves you in cash for the days the move takes. To see what a gap of that length can do to the price you buy back at, we measured every 4-session window in SPY’s daily history.

Each window is the change in the adjusted close from one session to the session four later. Four sessions is the validation day plus the three completion days in Rule 11870.

There were 8,493 windows from 29 January 1993 to 30 October 2026. In 45.13% of them SPY moved less than 1% either way, and in 26.20% it moved 2% or more. The median move was 1.13%.

The extremes are large. The worst window ran from 3 October to 9 October 2008, when SPY fell 17.80%; the best gained 17.92%. In 58.26% of windows the price ended higher, which is the more common way a sale costs you: you buy back fewer shares than you sold.

On the $75,572 position above, a 2% move is $1,511.44. That is the size of move SPY made in about one window in four, in one direction or the other.

Limits of this measure. It uses one fund, adjusted closes and sessions rather than calendar days, and real transfers can run longer than four sessions when a request is rejected or a holding needs instructions. An in-kind move avoids this risk entirely, because you hold the shares throughout. The windows are in the SPY 4-session moves file.

Retirement accounts and other special cases

An IRA moves to an IRA of the same kind. Shares cannot go from a taxable account into an IRA in kind, because IRA contributions are made in cash, and moving IRA holdings out to a taxable account is treated as a distribution.

A margin balance has to be dealt with first. The debt either moves with the account, if the new firm accepts it, or is paid off before the transfer.

Fractional shares often cannot move. They are usually sold to cash, which is a small realized gain or loss rather than a large one.

Questions people ask

How long does a brokerage transfer take?

Under FINRA Rule 11870, one business day to validate and three business days after that to complete, so about a week end to end once the request is correct. Rejections, nontransferable holdings and paper requests add time.

Can I trade during the transfer?

Not in the account being moved. On a full transfer, open orders are canceled at validation, so place any trade you need before the request goes in, or after the shares arrive.

Is transferring a brokerage account taxable?

Not if it moves in kind between accounts of the same type and owner. Selling to move cash is taxable in a taxable account, as the SPY example shows.

Is there a fee to transfer?

Often, at the old firm. The Motley Fool’s guide (updated July 2024) puts the usual outgoing fee at about $50 to $100, and not every firm charges one. Read the old firm’s fee schedule, then ask the new firm whether it will cover the charge.

Who starts the transfer?

The new firm. Contacting the old one first does not start anything.

When it fails

The account is liquidated instead of moved. The request went in as cash, or nobody asked, and a gain built over years is realized in a day. It shows up as a tax form the following year, long after the move looked finished.

The request bounces. A name, account number or account type that does not match the old firm’s records is sent back at validation, and the clock starts again.

A holding is stuck. A fund the new firm will not take sits at the old firm until you give instructions, so the old account stays open.

The cost basis is missing. Shares arrive without purchase history, and the gap is only noticed at the next sale.

Money trickles in after the old account is closed. Late dividends follow the six-month sweep rule, so check before closing.
