Tax software does the return. The adding machine does everything around it: checking what the client brought in, adding up the shoebox, proving a total before it goes into the software. DeskCalc is that adding machine, on screen, with a tape you can keep with the file.
What a tax-season tape needs
Six things a paper tape cannot do — and DeskCalc can.
Label every line
Type a comment next to any figure — the vendor, the form and box, the account — and add headings to split one tape into sections. Months later the tape still explains itself.
Fix a typo without running it again
Found a transposed figure on line 37 of 60? Click it, correct it, and every subtotal and total below recalculates. No second tape, no “which one is right”.
One tape per client
Keep several tapes open as tabs and save them together as a project — the client's receipts, the rental property and the charitable gifts in one file you can reopen when the IRS letter arrives.
A PDF for the workpapers
Export the tape to PDF for the client file or the portal, to Excel for a schedule, or print it on the office printer when someone wants paper.
Figures straight from the client's PDF
With Click & Calc you draw a box around a column of numbers on screen — a scanned statement, a brokerage PDF, a page you cannot copy from — and the figures drop onto the tape, already added up. The text recognition is built in. How Click & Calc works
Taxpayer data stays on the PC
DeskCalc runs offline. There is no account, no cloud and no upload; a tape is stored only where you save it. That keeps the calculator out of your data-security plan instead of adding a new service to it.
Where it saves time in a return
| Task | On the DeskCalc tape |
|---|---|
| Schedule C receipts | One heading per expense category, a comment per receipt, a subtotal per category and the grand total — on one tape. |
| 1099-B and brokerage statements | Pull the proceeds column off the PDF with Click & Calc and compare the total with the summary page. |
| Rental property | Income and expenses per property as separate tapes in one saved project. |
| Charitable contributions | Each receipt with the organisation's name as a comment — the tape doubles as the list. |
| Checking a client's own figures | Re-add their spreadsheet or bookkeeping totals independently and keep the tape as proof that you did. |
| Figures an AI assistant read | If Claude reads the receipts for you, DeskCalc Verify puts its figures on a tape — you confirm each line before anyone relies on the total. |
Seasonal staff, permanent licences
DeskCalc is a one-time purchase. The licences you buy for the season are still yours in May — there is no subscription to cancel and nothing to renew next January.
| Package | Price | Per seat |
|---|---|---|
| 1 licence | $29.95 | $29.95 |
| 5 licences | $119.95 | $23.99 |

The 10-licence package runs on terminal servers. More than ten seats, or a purchase order from the firm? Ask for a quote.
From accountants who use it
“We absolutely love our DeskCalc programs — so much better than ten-key calculators with tapes. Being able to export calculations to PDF or Excel is awesome.”
— Denise, CPA
“What a time saver. I just estimated gain on sale for a client and copied and pasted it right into Excel. I could never do that with an adding machine.”
— Review “Timesaver for CPA”, Microsoft Store (US), 2021
Set it up before the rush
Install it now, run a few of last year's files through it, and have it on every desk when the first W-2s arrive. The trial is free for 31 days with every feature, it works with the numeric keypad exactly like your 10-key, and it needs no account.
Coming from a printing calculator? What changes when you switch.
