January should not feel like this.

The letter arrives. Or you log into your Government Gateway. And the number staring back at you is bigger than you expected.

Sometimes much bigger.

Because nobody mentioned the payment on account. The extra 50 percent on top of your actual bill that HMRC demands upfront toward next year. The one that turns a £3,000 tax bill into a £4,500 demand. Due in three weeks.

You are not bad at running a business. You are not irresponsible with money. You just did not have the right system.

That is what this template fixes.

You Are Not Alone in This

Every January, thousands of UK sole traders face the same moment.

The shock. The scramble. The transfer from savings that were earmarked for something else. The mental calculation of what gets delayed this month to cover what HMRC needs now.

It is one of the most common financial emergencies in self-employment. And it is entirely preventable.

Not with expensive software. Not with an accountant on retainer. With a £9.99 spreadsheet that does the maths for you, every month, automatically.

What Changes When You Use This Template

You record a payment. Your tax estimate updates.

You record an expense. Your profit adjusts. Your January figure adjusts with it.

You check in once a month for twenty minutes. You know exactly what is coming.

No guessing. No surprises. No January crisis.

"I used to dread January every single year. Last year was the first time I actually knew what was coming. I had the exact amount saved. It felt like nothing." — Sarah, freelance copywriter

"The student loan repayment section alone was worth it for me. I had no idea how much I owed through Self Assessment until I saw it in the Tax Planner." — James, IT contractor

"I tried three different spreadsheets before this one. None of them calculated my actual tax bill. This one does it automatically." — Claire, graphic designer

Built on the Numbers HMRC Actually Uses

• Personal allowance: £12,570

• Basic rate tax: 20% — higher rate: 40%

• Class 4 NI: 6% up to £50,270, 2% above

• Student loan thresholds for all five plan types built in

• Payment on account calculation included

No estimates. No generic percentages. The real 2026/27 figures, built in.

The Honest Cost Comparison

A qualified accountant charges between £200 and £400 for a tax calculation session.

A missed payment on account can cost you £1,500 to £3,000 in unexpected January outgoings — money that was supposed to be yours.

Saving the wrong percentage all year, not knowing about the payment on account, getting to December with no records and three months of receipts to reconstruct — these mistakes cost real money.

This template costs £9.99.

It catches all of them.

At the basic rate it is also tax deductible, which means it effectively costs you £8.01.

Who This Is For

Just starting out? Set this up before your first transaction and you will never have a disorganised year.

January caught you out before? Catch up the current year in one afternoon. Make sure it never happens again.

Already using a spreadsheet? Replace it with one that actually calculates your tax automatically. Not a guess. The real number.

Have a student loan? All five repayment plan types are built in. Select your plan and the repayment appears in your January total automatically. Most sole traders only find this figure out in January. This template shows it to you all year long.
