RCT credits

The list in the books of every client payment on which the client held back RCT: the payment date, the invoice and its status, the amount deducted, the rate and the authorisation number, with totals, a year filter and a CSV download.

What it is for

RCT is the Irish construction tax that a principal contractor holds back when paying a subcontractor. When your client company's customer pays an invoice, they may keep part of it and pay that part to Revenue instead. That part is the RCT deducted.

In FSMCore RCT deducted is a credit, not a cost:

• It was paid to Revenue on the company's behalf, so it is a credit against the company's own tax.
• It settles the client invoice just like cash. An invoice is Paid when the cash received plus the RCT deducted reaches the total. See How the status follows payments.
• It is never a job cost and it is in no job margin.

RCT credits lists every payment on a client invoice that carries RCT deducted, one row per payment. You use it, and its CSV, to claim the credit.

What is in the list:

• Every payment on a client invoice where the RCT deducted is not 0.
• A payment that corrects an earlier figure downwards can carry a minus RCT amount. It is listed too, and the totals take it off.
• A payment that was removed in the office is not listed. See When a payment is removed or changed.
• Payments of a void invoice stay in the list, because the RCT was really deducted. Their Status says Void, so you can tell them apart. Payments of a deleted invoice are not listed.
• Payments on crew invoices are never listed. This list is about tax held back from the company, not tax the company holds back from its subcontractors.

Nothing can be changed here. FSMCore sends nothing to Revenue: the list only shows what the office recorded.

To open it, sign in to the books and choose RCT credits in the menu.

Who can use it

RCT credits is only in the menu while the Construction tax withholding (RCT) switch is on for the company. An owner or admin sets it in the office, see Features. With the switch off, the list leaves the menu and its address cannot be opened. Nothing is deleted: RCT that was already recorded is kept, still counts towards the invoice being paid, and the list is back when the switch is turned on again.

See The books for the other lists of the books.

Where the figures come from

An owner or admin records them in the office, in Record payment on a client invoice. Three fields there feed this list: RCT rate, RCT deducted (total to date) and Deduction authorisation no. See RCT deducted.

Things to know when a figure looks wrong:

• Mark paid never records RCT. It records the whole balance as cash, so such a payment is not in this list.
• The rate and the authorisation number are optional in the office. When they were left empty, the list shows "-".
• The RCT SIN is not typed on the payment. It is the SIN of the site of the invoice's job. See RCT site identifier (SIN).

You cannot correct anything from the books. Ask an owner or admin of the company.

The list

The newest payment date is at the top. Rows do not open anything when clicked. There are no row actions and no bulk actions.

With no rows the list says No RCT deducted on any payment yet.

A toggle switches between a table and cards, as on the other lists. See List and card layout. On a phone the cards are shown. A card has the invoice number, then Client, the status of the invoice, Payment date, RCT deducted, Gross covered, Rate, RCT SIN and Authorisation no. A card shows every figure, whatever the width of the screen. In the table, on a narrow screen some columns are hidden, and a table that is still too wide scrolls sideways inside its own box.

Columns

Some columns are only shown on a wide screen, so the table fits. Payment date, Invoice, Status, Client, RCT deducted and Authorisation no. always show.

Amounts are shown in the currency the invoice was issued in. If the company changed its currency later, the rows of the older invoices keep the currency of those invoices.

Totals

The foot of the table adds up two columns:

• Total RCT under RCT deducted: the RCT of the rows the list shows.
• Total under Gross covered: the cash plus RCT of the same rows. It shows when that column shows, from 1536 px wide.

The totals are exact, to the cent, and follow the filter and the search. Choose a year and they are the totals of that year. A correction with a minus amount is taken off.

When the list runs over more than one page, the foot has two lines: This page for the rows on the page you see, and a line for all rows.

The totals carry the currency of the invoices. Amounts in two currencies are never added into one figure: when the rows hold invoices issued in two currencies, each total shows one amount per currency, with a plus sign between them.

Filters

There is one filter, Year. It lists every year that has a payment with RCT, plus the current year, newest first. Choose a year to see only the payments dated from 1 January to 31 December of that year. The filter applies as soon as you pick it. There is no Apply button. The filter goes by the payment date, not by the invoice date.

Search

The search box looks in the Invoice number, the Client name and the Authorisation no. You do not need the exact spelling: words in any order and small typos still find the row.

Download CSV

Download CSV is the button at the top of the page. It downloads the rows the list shows right now: the year filter, the search and the sort order are applied.

1. Choose the Year if you want one year only. The list changes at once, and the file follows the list.
2. Press Download CSV.

The file is named rct-credits.csv, or with the year when one is chosen, for example rct-credits-2026.csv.

The file ends with one Total line per currency, with the total of Gross covered and of RCT deducted in that currency and the currency in the Currency column. A company that always worked in one currency gets one Total line.

Good to know:

• The file opens correctly in Excel, accented names included.
• Amounts have no currency sign and no thousands separator, so they add up in a spreadsheet.
• The RCT SIN is not in the file. Read it from the list on a screen at least 1024 px wide.
• The file always has all nine columns, also on a narrow screen where the list hides some.
• The amounts of the file are plain numbers. The Currency column says which currency each row is in: the currency its invoice was issued in.
• The file ends with one Total line per currency, each with the gross covered and the RCT deducted of that currency. Amounts of different currencies are never added together. With no rows, the file ends with one Total line of 0.00 in the company's currency.
• The file holds all rows of the list, not only the page you see.

When a payment is removed or changed

The list always shows the payments as they are now.

A payment is removed. An owner or admin can remove a payment that was recorded by mistake. See Remove a payment. A removed payment leaves RCT credits at once, and the totals drop by its RCT. Before removing a payment with RCT, the office is warned: "This payment carries EUR 200.00 RCT deducted: it leaves RCT credits. If the credit was already claimed with Revenue, correct it on ROS; FSMCore cannot undo that." So if you already claimed that credit, it is up to you and the company to correct it with Revenue.

The removed payment is not lost. It stays in the invoice's own payments, greyed, with who removed it and why. In the books, open Client invoices, then the ⋮ menu on the invoice, then Payments. See In the books.

The RCT figure is corrected. The office corrects a wrong RCT amount by typing the right total in Record payment. FSMCore stores the difference as a new payment. When the right total is lower, that payment carries a minus RCT amount, so the list gets a second row and the totals come out right.

The date is corrected. With Edit payment the office can change a payment's date. The row then shows the new date and can move to another year. The amount and the RCT deducted cannot be changed that way. See Edit a payment.

The invoice is voided. The payments of a void invoice cannot be removed, and they stay in this list and in its totals: the RCT was really deducted. The Status of those rows changes to Void, in the list and in the CSV.

Nobody is emailed about any of these. A total you downloaded earlier can therefore differ from the list today. Download the CSV again before you file.

What happens after

• A payment with RCT is in the list as soon as the office saves it.
• Reading the list and downloading the CSV change nothing and send no email.
• Each payment, with its RCT, is also in the History of its invoice. See History.

Common mistakes

No RCT credits in the menu. The Construction tax withholding (RCT) switch is off for the company, or you are not an owner, admin or accountant.

A paid invoice with RCT is missing. The office used Mark paid, which records the whole balance as cash. Ask them to remove that payment and use Record payment with the RCT rate.

The RCT SIN shows "-". The invoice has no job, or the job's site has no SIN yet. An owner or admin types the SIN on the site.

Gross covered or Rate is missing. In the table they only show from 1536 px wide. Widen the window, switch to the cards, or use the CSV, which always has both.

One invoice has two rows. Each row is one payment. An invoice paid in stages, or with a corrected RCT figure, has several.

A row has a minus amount. It is a correction: the office lowered the RCT total of that invoice. The totals already take it off.

The total changed since last time. A payment was removed, added or corrected, or its date was moved into another year.

A row says Void. The invoice was voided after that payment was recorded. The payment stays in the list and in the totals, because the RCT was really deducted. Ask the office what happened before you claim it.

The year in the list is not the year of the invoice. The Year filter goes by the payment date.
