## About

TaxHeaven gives self-employed workers, freelancers, sole traders, and landlords instant UK tax answers using HMRC-published rates, right inside ChatGPT.

8 tools cover the full self-employed tax journey:
• Calculate income tax, National Insurance, and take-home pay (England and Scotland)
• Check if Making Tax Digital (MTD) applies to you and when it starts
• See all your tax deadlines with countdown timers
• Work out your payments on account and how much to save monthly
• Add or remove VAT, compare the Flat Rate Scheme, check registration thresholds
• Find out if an expense is tax-deductible under HMRC rules
• Calculate capital allowances on business equipment and vehicles
• Scan receipts and categorise them for your tax return

All calculations use official HMRC rates for 2024-25 through 2026-27. No sign-up required, no data stored, MTD compliance completely free from HMRC-recognised software.
