# UK Income Tax Calculator MCP > UK Income Tax Calculator handles complex British tax law for immediate financial answers. Calculate your exact income tax liability, National Insurance contributions (Class 1 and Class 4), and net take-home pay. It accounts for personal allowance tapering when earnings exceed £100k. ## Overview - **Category:** finance - **Price:** Free - **Tags:** uk-tax, income-tax, national-insurance, personal-allowance, financial-planning ## Description This MCP lets you figure out exactly how much money you take home from a paycheck in the UK. Tax laws are complicated, changing constantly—especially with rules like Personal Allowance tapering after you hit £100,000 in annual earnings. Instead of wading through HMRC guidelines or outdated tax tables, your agent performs precise calculations for all required contributions. When you need to know a total financial picture, the system can generate a full tax summary report that breaks down income tax, National Insurance (NI), and what’s left over after deductions. You can also drill down into specific components. Need to calculate just your employee NI contribution? Or maybe you're looking at self-employed Class 4 contributions? This MCP handles it all. Since Vinkius hosts this tool in the catalog, you connect once from any compatible client and gain access to accurate tax figures instantly. ## Tools ### get_tax_summary_report Creates a comprehensive report that totals your income tax, NI payments, and final net take-home pay for a full picture of your finances. ### calculate_income_tax Determines the exact UK Income Tax liability based on current annual earning brackets. ### calculate_national_insurance Computes your National Insurance contribution, covering both employee (Class 1) and self-employed (Class 4) payments. ## Prompt Examples **Prompt:** ``` How much income tax will I pay on £50,000 annual earnings? ``` **Response:** ``` On an annual income of £50,000, your estimated income tax is £7,430 (based on standard thresholds). ``` **Prompt:** ``` Calculate my NI contribution for Class 1 with £30,000 earnings. ``` **Response:** ``` Your National Insurance Class 1 contribution on £30,000 is approximately £245.60. ``` **Prompt:** ``` What is my net take-home pay if I earn £120,000 as an employee? ``` **Response:** ``` With £120,000 annual earnings as an employee, your estimated net take-home pay after Income Tax and Class 1 NI is approximately £84,500. ``` ## Capabilities ### Determine full financial liability Generate a complete report detailing income tax, National Insurance contributions, and final take-home pay. ### Calculate specific income taxes Figure out your UK Income Tax liability based on current tax brackets. ### Determine NI payments Compute National Insurance contributions for both employee (Class 1) and self-employed (Class 4) statuses. ## Use Cases ### An employee needs to know their true salary after deductions A new hire asks their manager, 'What's my take-home pay if I make £50k?'
