OpenTaxCalculator VS ShellNewHandler

• Likely free to access
  I can't browse the site, so I can't confirm this. Online tax calculators with 'open' in the name are typically free and need no account, so users can get quick estimates without paying for tax software.
• Quick estimates
  Web-based tax calculators usually give instant estimates of tax liability, take-home pay or refunds from a few inputs. That is useful for planning and what-if scenarios without filing a full return.
• No installation needed
  A browser-based tool works on any device with internet access. Users don't have to download or maintain software.
• Possible transparency
  The name suggests an open or transparent approach, such as visible assumptions or formulas. Please check the site to confirm whether it publishes its methodology or source code.

Possible disadvantages

• Unverified accuracy and currency
  I couldn't verify how accurate the site is or how often it updates tax brackets, deductions and credits. Calculators that lag behind yearly tax law changes can give misleading results, so check the figures against official government sources.
• Estimates only, not tax advice
  Online calculators generally can't capture complicated situations such as self-employment, multiple income sources, investments, or state and local rules. They don't replace a tax professional or official filing software.
• Privacy and data handling concerns
  Entering income and personal financial details into any third-party website carries some privacy risk. Review the site's privacy policy and avoid entering sensitive identifiers such as Social Security numbers.
• Limited jurisdiction or feature coverage
  Many free calculators cover only certain countries, tax years or filing types. They may lack advanced features such as e-filing, form generation, audit support or detailed reports.
• Uncertain support and reliability
  Smaller independent tools may have limited documentation, customer support or a track record of maintenance. Users may have little recourse if the calculator has errors or is discontinued.

• I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?

  Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago

• This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?

  I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
