Financial Disclaimer
Important: All figures on IncomeFix are estimates only
The results provided by IncomeFix calculators are approximate estimates based on publicly available rates, thresholds, and rules for the 2026/27 UK tax year. They are intended to give you a general indication of your likely entitlement or liability and should not be treated as exact figures. Your actual tax, benefits, or take-home pay may differ significantly depending on your individual circumstances.
Not financial advice
IncomeFix is an informational website. Nothing on this website constitutes financial, tax, legal, or accounting advice. The information and calculator results provided are for general informational purposes only and should not be relied upon as a substitute for professional advice tailored to your specific situation.
Before making any financial decisions — including claiming benefits, filing tax returns, changing your employment arrangements, or starting a side hustle — you should consult a qualified professional such as a chartered accountant, certified financial planner, or benefits adviser. Free advice is also available from organisations such as Citizens Advice, MoneyHelper, and Turn2us.
Not affiliated with HMRC or DWP
IncomeFix is an independent, privately operated website. We are not affiliated with, endorsed by, or connected to HM Revenue & Customs (HMRC), the Department for Work and Pensions (DWP), or any other UK government department or agency. Our calculators are not official government tools, and our results do not reflect official HMRC or DWP assessments of your entitlement or liability.
For official information about UK tax, benefits, and entitlements, please visit GOV.UK, which is the authoritative source for all UK government services and information.
Limitations of our calculators
Our calculators are simplified models of complex tax and benefits systems. While we strive for accuracy, they cannot account for every possible circumstance. Known limitations include:
- Our benefits calculator provides an indication of potential entitlement. Actual eligibility is determined by the DWP or your local council through a formal assessment process. Many benefits have complex interaction rules that our calculator simplifies.
- Our tax calculators use standard assumptions about tax codes, National Insurance categories, and allowances. If you have a non-standard tax code, multiple income sources, or complex arrangements such as salary sacrifice, the estimates may not reflect your actual position.
- Our side hustle tax calculator estimates are based on the expenses you declare. The actual allowability of expenses is determined by HMRC, and some expenses you claim may be disallowed on review.
- Rates and thresholds may change during the tax year following a Budget or other fiscal event. We update our calculators as soon as practicable after changes are announced, but there may be a delay.
- Scottish income tax rates differ from the rest of the UK. Our calculators account for this where applicable, but you should verify which tax regime applies to you.
No liability
To the fullest extent permitted by law, IncomeFix accepts no liability for any loss or damage arising from your use of our calculators or reliance on any information provided on this website. This includes, without limitation, any financial loss, missed benefits, tax penalties, or other adverse consequences resulting from decisions made based on our estimates.
Verify with official sources
We always recommend cross-referencing our estimates with official sources. Key resources include:
- GOV.UK Benefits Checker — Official tool to check what benefits you could be entitled to.
- HMRC Income Tax Estimator — Check your income tax estimate for the current year.
- HMRC Self Assessment — File your tax return and check your actual tax liability.
