Reading your Tax estimate in Keepr

What every number on the Summary page Tax Estimate card means, how Keepr works it out, and what it's not telling you.

The Tax Estimate card on the Summary page is Keepr's live answer to how much will I owe HMRC this year?. It updates every time you raise an invoice or log an expense, and it uses HMRC's published bands and rates rather than rough rules of thumb. This guide walks through every figure on the card and explains how Keepr arrives at it.

Which version of the card you see depends on the Business Type set in Settings → Business. Sole traders get the Self Assessment estimate (Income Tax + National Insurance). Limited companies get the Corporation Tax estimate.
The Tax Estimate card on the Summary page for a sole trader, showing Income Tax, Class 2 NI and Class 4 NI lines with a PROJECTED tag in the title.
Sole trader view: the headline is total estimated tax for the year, with band-by-band detail in the mini-chart.

The big number

The large figure on the card is the total estimated tax for the current tax year (sole traders) or the current accounting period (limited companies). Underneath it sits an effective rate - the percentage of your total income that ends up going to HMRC once allowances and bands have done their work.

The pill next to the title shows the tax year, for example 2025/26. Sole traders also see a PROJECTED tag when Keepr has annualised your year-to-date profit to estimate the full-year figure (see Why it says ‘Projected’ below).

Sole traders - what each line means

The mini-chart shows up to five rows. Tax charges are in red; PAYE already paid (a credit) is in green.

LineWhat it is
Taxable ProfitYour income minus expenses for the tax year so far - the figure HMRC actually taxes. Shown when there's room.
Income TaxTax on your profit (plus any employment / savings / dividend income you've entered), stepped through HMRC's 20% / 40% / 45% bands.
Class 2 NIA flat weekly slice of National Insurance for the self-employed. £3.45 a week (£179.40 a year) in 2025/26; £3.65 a week (£189.80 a year) in 2026/27. Counts towards your State Pension.
Class 4 NIPercentage-based National Insurance: 6% of profit between £12,570 and £50,270, then 2% on anything above £50,270.
Student LoanShown only if you've told Keepr which plan you're on (Plan 1, 2, 4, 5 or Postgraduate). 9% of income above the plan's threshold; 6% for Postgraduate.
Less: PAYE paidA credit for tax your employer already took off your salary. Shown only if you've recorded employment income and the tax paid on it.
Class 2 vs Class 4 NI - the names are confusing. Class 2 is the small flat fee that keeps you contributing to the State Pension; Class 4 is the percentage that's roughly the self-employed equivalent of an employee's National Insurance.

Sole traders - the full breakdown

Click anywhere on the card to open the Tax Estimate breakdown. The modal walks through the same maths HMRC would, in five sections: Income, Allowances, Tax bands, National Insurance & Student Loan, and Adjustments.

The Tax Estimate breakdown modal, showing Income, Allowances, Tax bands and National Insurance sections with totals on the right.
The breakdown opens when you click the card. Every figure is explained with a short note underneath.

Personal Allowance

The slice of income everyone gets tax-free each year - £12,570 for 2025/26 and 2026/27. Two things can change yours:

AdjustmentEffect
£100k taperIf your total income is over £100,000, you lose £1 of Personal Allowance for every £2 above. It disappears entirely at £125,140.
Marriage AllowanceIf your spouse has transferred theirs to you, you get an extra £1,260. If you've transferred yours to your spouse, your allowance drops by £1,260.

Tax bands (Income Tax)

BandRateOn the slice of income…
Basic rate20%up to £50,270
Higher rate40%between £50,270 and £125,140
Additional rate45%above £125,140

Keepr stacks income in HMRC's prescribed order: self-employment profit and PAYE first, then savings interest, then dividends. Each layer uses any unused Personal Allowance from the layer above it.

Savings and dividends

If you've entered savings interest or dividends in your tax options, the modal also accounts for:

AllowanceHow much
Personal Savings Allowance£1,000 tax-free interest if you're a basic-rate taxpayer, £500 if higher-rate, nothing if additional-rate.
Starting Rate BandUp to £5,000 of savings interest at 0% - but only if your other income is below your Personal Allowance, then tapered away.
Dividend AllowanceFirst £500 of dividends taxed at 0% regardless of your band.

Pension and Gift Aid relief

Personal pension contributions and Gift Aid donations both push the basic-rate threshold up by their gross amount (your contribution × 1.25), so a slice of income that would have been taxed at 40% drops back to 20%. If you've entered either figure in your tax options, you'll see a Pension & Gift Aid relief line in the Allowances section.

Why it says ‘Projected’

If a PROJECTED tag is showing in the card title, Keepr is estimating your full-year tax based on your year-to-date profit, scaled up to a year:

Projected profit = YTD profit × (days in tax year ÷ days elapsed). The projection only starts after the first 30 days of the tax year - that stops a single big April invoice generating wild extrapolations.

The modal shows both figures: your year-to-date profit and tax (the legally-accurate number for what you've earned so far) and the projected full-year figure (the headline on the card). Only your self-employment profit is projected. Manually entered annual figures - employment, savings, dividends, pension contributions, Gift Aid - stay as you typed them.

Limited companies - Corporation Tax

The Tax Estimate card on the Summary page for a limited company, showing Taxable Profit, Corporation Tax, Rate Band and Set Aside per Month, with an accounting period progress bar.
Limited company view: Corporation Tax, the rate band that applies, and a suggested monthly amount to set aside.

If your Business Type is Limited company, the card title changes to Corporation Tax and the chart shows four lines instead:

LineWhat it shows
Taxable ProfitIncome minus expenses for the accounting period so far.
Corporation TaxYour estimated CT bill for the full accounting period.
Rate BandWhich of HMRC's three CT bands applies to you.
Set Aside / MonthTotal CT ÷ 12 - a suggested monthly transfer into a tax-savings pot so the cash is there on the due date.

The three Corporation Tax bands

BandRateWhen it applies
Small profits rate19%Profits up to £50,000.
Main rate25%Profits of £250,000 or more.
Marginal relief~19% → 25% slidingProfits between £50,000 and £250,000.
Marginal relief stops a cliff edge at £50k. Without it, a company on £50,001 of profit would pay 25% on the lot - nearly £3k more than at £50,000. The relief tapers the effective rate smoothly from 19% to 25% across the £50k-£250k band.

Your accounting period is set by the Financial Year End in Settings → Business. The progress bar under the chart shows how far into the period you are.

Worked example - £58,000 taxable profit

To put the maths in context, here's how a freelancer with £58,000 of taxable profit in 2025/26 would be estimated. Both the sole-trader and limited-company versions are shown so you can see the contrast.

Sole trader on £58,000

ComponentWorkingAmount
Personal AllowanceStandard, no taper (well under £100k)£12,570
Basic rate Income Tax20% on £37,700 (£12,570 to £50,270)£7,540
Higher rate Income Tax40% on £7,730 (£50,270 to £58,000)£3,092
Class 2 NI£3.45 × 52 weeks£179
Class 4 NI6% on £37,700, then 2% on £7,730£2,417
Total estimated tax£13,228

Effective rate: roughly 22.8% of profit. That's the figure the card shows underneath the headline.

Limited company on £58,000

ComponentWorkingAmount
CT at main rate£58,000 × 25%£14,500
Less marginal relief0.015 × (£250,000 − £58,000)−£2,880
Corporation Tax£11,620
Set aside per month£11,620 ÷ 12£968

Effective rate: roughly 20.0%. Note this is just the company's bill - if you take dividends out, you'll pay personal tax on those too on your own Self Assessment.

What's not factored in

The Tax Estimate is an estimate, not your return. It uses what Keepr knows about your business and the figures you've supplied. The real number on your Self Assessment or CT600 will differ - an accountant, a fresh receipt, or an HMRC adjustment can all move the dial.
Not included in the estimateWhere it actually goes
Capital gains, property income, foreign incomeFiled separately on your Self Assessment return.
Marriage Allowance, Student Loan, voluntary Class 2 NIOnly counted if you've enabled them on the Tax page under More tax options.
Pension contributions, Gift AidOnly counted if you've entered the amounts in More tax options.
Employment income / PAYE taxOnly counted if you've entered the year totals in More tax options.
Director's dividends (limited companies)Taxed on the director's personal return, not the company's CT.

Frequently asked questions

Is the Tax Estimate an official HMRC figure?
No - it's Keepr's calculation using HMRC's published rates. The real figure on your Self Assessment return or CT600 may differ once your accountant, fresh receipts, or HMRC adjustments are factored in.
Why does my estimate keep changing?
It updates live as you record income and expenses. Every new invoice raises your profit (and tax); every new expense reduces it. That's the point - you always see a current picture.
Why does it say ‘Projected’?
Once you're 30 days into the tax year, Keepr annualises your year-to-date profit to estimate your full-year tax. The modal shows both your year-to-date tax (legally accurate so far) and the projected full-year figure.
I'm a sole trader but the card says Corporation Tax. Why?
Your Business Type is set to Limited company. Switch it to Sole trader in Settings → Business and the card will rebuild as a Self Assessment estimate.
Does it cover Scottish income tax rates?
Not yet - Keepr currently uses the UK-wide bands (England, Wales and Northern Ireland). Scottish residents will see a close-but-not-exact figure for now.
Does it include VAT?
No. VAT is a separate report - see Tax Summary. The Tax Estimate covers Income Tax + NI (sole trader) or Corporation Tax (limited company).
Where do I change the inputs?
Business Type and Financial Year End live in Settings → Business. Student Loan plan, Marriage Allowance, voluntary Class 2 NI, pension contributions, Gift Aid, employment income and savings/dividends figures live on the Tax page under More tax options.
