Tax Money Kit
Know what to set aside from every 1099 payment, and what to send the IRS by January 15.
An Excel file for freelancers, contractors, and side hustlers. Open it in Excel or Google Sheets. Log what comes in and what you spend. It gives you your Schedule C totals, your self-employment tax, and a quarterly payment based on the IRS safe-harbor rule. Setup takes about five minutes. $47 once.
One-time payment. Instant access. 30-day refund.
Or run the free 2026 estimate first. It answers once. The sheet tracks the year.
The problem, plainly
No one withholds tax from a 1099 check. The IRS still expects payments four times a year, and the next one is due January 15, 2027. Most people guess a percentage, or pay nothing and hope. Both can end with a bill and a penalty in April. The date, the safe-harbor percentages, and the ways to pay are on the January 15 estimated tax guide.
What you get
- A set-aside % for every payment. Log a payment and the sheet shows how many dollars to move to tax savings. The number updates as your year changes.
- Your next IRS payment, in dollars. Two numbers side by side: the payment that meets the IRS safe-harbor rule, and the payment that covers your full estimated bill so April holds no surprise.
- Real self-employment tax math. 15.3% on 92.35% of net profit, the 2026 Social Security wage base, and Additional Medicare when it applies. These follow the 2026 Form 1040-ES worksheet. It is not a flat guess.
- Expenses sorted to Schedule C lines. Pick a category and the line number fills in. Meals are figured at 50%. Fees from platforms and processors are handled so gross income is not counted twice.
- A mileage log that knows the date. The IRS business rate is 72.5 cents through June 30, 2026 and 76 cents from July 1. The sheet picks the right one for each trip.
- A home office line. Uses the simplified method: $5 per square foot, up to 300.
- A catch-up view. If you skipped the first three payments this year, it shows what is left to pay by January 15.
- A one-page summary for your tax preparer. Schedule C totals, miles, and every payment with its confirmation number.
- A sample copy filled with made-up numbers, so you can see it working before you type anything.
- The 2027 edition, free, when the IRS publishes 2027 figures.
Who it is for
- 1099 contractors, freelancers, gig workers, creators, and consultants who file Schedule C
- People with a W-2 job and a side business (it counts your paycheck withholding)
- Anyone starting late in the year who needs a clean number for January 15
Who it is not for
- S-corporations and partnerships
- Anyone who needs state tax math (you enter your own state %)
- Anyone who wants bank feeds or an app that categorizes for you
How it works
- Buy. You download an Excel file (.xlsx) from Whop. Open it in Excel, or upload it to Google Drive and open it in Google Sheets.
- Fill in six cells: filing status, W-2 pay and withholding (if any), and last year's total tax.
- Log your payments, expenses, and miles as they happen.
- Move the set-aside amount to savings. Pay the IRS by each due date using IRS Direct Pay or EFTPS.
Why a sheet and not an app
- You pay once. Many tax apps bill every month or every year. This file stays yours if you never pay again.
- Your numbers stay in your own Google Drive or computer. We never see them.
- Every rate in the sheet sits on one Settings tab with a link to the IRS page it came from, so you can check any number.
Optional: Year-Round updates ($49/year)
Get each new tax-year edition, updates when the IRS changes a rate mid-year, and an email reminder 14 days before each IRS due date. It is optional and billed once a year. You get a reminder 7 days before it renews, and you can cancel anytime. The $47 kit works fine without it.
FAQ
Is this tax advice?
No. It is an educational recordkeeping and estimating tool. It does not prepare or file a return. For advice on your situation, talk to a CPA or enrolled agent.
Do I need Excel?
No. The kit is an Excel file (.xlsx) you download from the checkout. Open it in Excel, or upload it to Google Drive and open it in Google Sheets.
What does "safe harbor" mean?
In general, the IRS does not charge the underpayment penalty if your withholding and on-time estimated payments are at least the smaller of 90% of this year's tax or 100% of last year's tax (110% if last year's adjusted gross income was over $150,000). The sheet does this math for you. Source: IRS, Form 1040-ES.
When are the payments due?
For 2026 they are due April 15, June 15, and September 15, 2026, and January 15, 2027. If a date falls on a weekend or legal holiday, the next business day counts. Source: IRS, 2026 Form 1040-ES.
I missed earlier payments. Will this fix a penalty?
It shows what to pay now. It does not erase a penalty for an earlier missed payment, and it does not calculate one. The IRS figures that on Form 2210.
Does it do state taxes?
No. You can enter a state set-aside percentage and the sheet will include it in the amount to set aside.
I also have a W-2 job. Does that matter?
Yes. Enter your expected wages and withholding. The sheet counts the withholding toward your payments and caps Social Security tax at the 2026 wage base.
Does it work for 1099-K payments from apps and marketplaces?
Yes. Log the gross amount and the fees on the same row. Fees go to Schedule C line 10.
What if the IRS changes something?
Every rate sits in one Settings tab with its source. The 2027 edition is free for buyers. The Year-Round add-on sends you each new edition and mid-year updates.
Is my data private?
The file lives in your own Google Drive or on your computer. Nothing you type is sent to us.
30-day refund.
If the kit does not give you a set-aside percentage and a next-payment amount within your first session, email us within 30 days of purchase for a full refund. No forms.
