## What is TaxUK IQ?

TaxIQ UK is the UK's most complete salary, tax and payroll calculator — a premium financial dashboard that shows exactly where your money goes and how much you really keep.

Enter your salary and watch every figure update instantly: income tax, National Insurance, pension, student loans, take-home pay and effective tax rate. Built on the latest HMRC rules, with historical tax years available so you can compare year on year.

WORKS FOR HOW YOU'RE PAID • Annual, monthly, weekly, daily or hourly pay — converted automatically • Overtime, commission, allowances and one-off payments • Variable pay tracking: log each payslip as it arrives for a running year-to-date picture • Bonuses: fixed or a percentage of salary, at any frequency, with real-payment tracking

EVERY UK NATION • England, Scotland, Wales and Northern Ireland • Full tax-code support, emergency codes, Marriage Allowance and Blind Person's Allowance • Validated against real payslips to the penny

PENSIONS & SALARY SACRIFICE • Auto-enrolment, salary sacrifice, net pay and relief-at-source arrangements • Independent employee and employer contributions • Additional Voluntary Contributions, including AVCs from bonuses • EV, cycle-to-work, tech and other sacrifice schemes

BENEFITS IN KIND • Company cars with CO₂/electric-range lookup, medical, dental and more • Both P11D and payrolled (real-time) reporting — ready for the HMRC transition • Employer Class 1A NI shown for context

BEYOND YOUR PAYSLIP Track all your income in one consolidated tax position: • Self-employment — log income and itemised expenses by pay window, with quarterly and annual totals • Rental property — Property Income Allowance, Rent-a-Room and mortgage-interest relief • Side hustles — with the £1,000 Trading Allowance • Savings interest, dividends and capital gains — against the correct allowances • Pension income — state pension, drawdown, annuity and tax-free lump sums

MAKING TAX DIGITAL Preparing to self-report? TaxIQ UK checks whether you're within scope, shows the phased thresholds, and breaks your income into HMRC's quarterly update windows with filing deadlines — derived from the real dates you log.

PREMIUM DASHBOARD & CHARTS • Large, animated KPI cards for every figure that matters • Salary breakdown, income-tax-by-band, waterfalls and cashflow charts • "This Year at a Glance" summary with clear positive/negative colouring • Effective and marginal tax rates at a glance

SCENARIOS & REPORTS • Save unlimited scenarios — current job, a new offer, a promotion, higher pension, retirement • Load, duplicate, rename and compare • Export professional PDF and CSV reports to share or keep

PRIVATE BY DESIGN • Everything is calculated on your device • Privacy Mode instantly hides sensitive figures • Face ID / Touch ID app lock • Optional iCloud sync keeps your data in step across iPhone and iPad

BEAUTIFUL & ACCESSIBLE • Native SwiftUI design for iPhone and iPad, portrait and landscape • Full Dark Mode, Dynamic Type and VoiceOver support • Smooth animations and instant, offline calculations

AI INSIGHTS (PREMIUM) Personalised, plain-English observations drawn purely from your own numbers — such as the tax impact of a bonus, whether extra pension could help, or how much salary you'd need for a target take-home. Guidance based on your figures, not financial or tax advice.

TaxIQ UK Premium unlocks unlimited scenarios, advanced charts, reports, cloud sync, AI insights and an ad-free experience.

Important: TaxIQ UK provides estimates from the figures you enter to help you understand and plan your finances. It is not tax advice and not a substitute for HMRC or a qualified accountant. Always check figures against your payslip and official guidance.

### 1.4 — 2026-10-24

This update brings major new tools to help you manage your whole household's finances, not just your salary.

MORTGAGE TRACKER
Track your mortgage from setup to payoff. Log payments and overpayments, record interest rate changes over time, and see your running balance update automatically. A new Payoff Calculator lets you compare "stay as you are" against overpayment scenarios side-by-side, showing how much time and interest you could save. Dashboard KPIs show what you've borrowed, paid, still owe, total interest, and your available equity based on your property value. Save and load multiple mortgage scenarios, just like your tax scenarios.

SMARTER, UK-ACCURATE INTEREST CALCULATIONS
Mortgage interest now accrues on every calendar day, including weekends and bank holidays, exactly as your bank calculates it. Payment and collection dates automatically roll to the next (or previous) UK working day when they fall on a weekend or bank holiday, using up-to-date England & Wales, Scotland, and Northern Ireland bank holiday calendars. You can choose whether interest should be calculated to the contractual date or the actual collection date, giving you full control to match your own bank statement.

BUDGETING TAB
Plan your household spending across mortgage/rent, utilities, insurance, council tax, subscriptions, loans, gym memberships, banking charges, charity giving, professional bodies, and more. See monthly vs. annual commitments separately, track regular savings and fuel costs, and view a KPI dashboard showing exactly where your money goes compared to your take-home pay. Save, load, and clear budget plans independently from your tax scenarios.

PARTNER INCOME
Add your partner's income, either a full PAYE calculation or a simple net pay entry, so your household budgeting reflects your combined financial picture, not just your own.

PENSIONS TRACKER
Enter details for all your pensions, current and legacy. For current pensions, see a projected retirement income based on your chosen retirement date. For legacy pensions, see 4% growth projections to maturity, including the option to take a tax-free lump sum. If you have several pensions taken in different years, see a combined summary of income and tax for each year, calculated using the tax rules that will apply in that year.

SELF-ASSESSMENT AND MAKING TAX DIGITAL
Self-employment income can now be logged with proper date ranges rather than single entries, fully itemized expense categories aligned with HMRC guidance, Class 2/4 National Insurance, and payments on account. The Making Tax Digital calculator is now built directly into your Other Income overview.

OTHER IMPROVEMENTS
Refined, more modern interface across the app. Improved keyboard handling, so entry fields no longer get hidden. Face ID sign-in reliability fixes. Subscription options now include both Monthly and Lifetime, even if you're switching plans. General performance and stability improvements.

Thank you for using TaxIQ UK! As always, we'd love to hear your feedback.

### 1.3 — 2026-10-17

This is our biggest update yet, adding four major new tools to help you manage your whole financial picture — not just your payslip.

Household Budgeting Take control of your monthly and annual spending with a brand-new Budgeting tab. Track 13+ categories including Housing, Utilities, Transport, Groceries, Insurance, Subscriptions, Banking Charges, Charity, and Professional Bodies — split cleanly between monthly and annual billing so nothing gets double-counted. Budgeting now pulls in your PAYE take-home pay automatically, and — if you've added a partner — their income too, giving a true household view of what's coming in versus what's going out.

Partner Income Managing money as a couple? Add your partner's income alongside your own. Choose full PAYE calculation (tax code, NI, pension, student loan — everything) if you want the same detail as your own numbers, or a simple net-pay entry if you just need the headline figure. Either way, it feeds straight into your household Budgeting page so you can plan together with confidence.

Mortgage Tracker A powerful new way to follow your mortgage from today through to being mortgage-free. Enter your balance, rate, and term, then track real payments as they happen with full UK bank-holiday-aware interest accrual — so projections match how your lender actually calculates things, not just a simplified estimate. Log rate changes over time, record one-off or recurring overpayments, and see their exact impact on your payoff date and total interest paid. A dedicated Payoff Calculator lets you model "what if I overpaid by £X a month?" scenarios, and a full History & Audit Trail keeps a clear record of every payment, rate change, and overpayment you've logged.

Pensions Tracker Bring every pension you have — workplace, personal/SIPP, legacy, Defined Benefit, and State Pension — into one place. Current pensions project forward using your actual PAYE contribution figures; legacy (frozen) pots grow at a fixed assumption to a maturity date you set. New this release: choose whether you take a tax-free lump sum at all, and set exactly what percentage (up to 25%) rather than always assuming the full amount — it now feeds directly into every projection and income estimate.

We've also made pension income tax-year-aware: if you plan to take one pension in 2030 and another in 2037, each is now assessed against the tax rules for the specific year it's actually paid, rather than today's rules applied to everything. And if more than one of your pensions falls in the same tax year, a new "Payments By Year" summary calculates a combined tax estimate across all of them together — more accurate than adding up each pension's standalone figure, since a bigger combined income pushes more into higher-rate bands.

Also in this release • General performance and stability improvements across the Calculator, Other Income, and Making Tax Digital pages • Refined UI consistency across every tab for a cleaner, more modern feel • Various bug fixes based on your feedback

As always, every figure in TaxIQ UK is an estimate to help you plan — not financial or tax advice. For anything that affects your actual tax return or mortgage, please check with HMRC, your lender, or a qualified adviser.

Thank you for using TaxIQ UK — we'd love to hear what you'd like to see next!
