Five good checks to do in April
- Open Tax Drag Calculator and rebuild your new-year baseline.
- Run Adjusted Net Income Calculator if HICBC, Tax-Free Childcare or the £100,000 taper matter.
- Check ISA vs GIA before new taxable investing leaks build up again.
- Use Pension Annual Allowance if contributions are large enough that carry forward or taper might matter.
- Re-open Self-employed Toolkit if the year change affects VAT, profit reserves or extraction.
Why April matters so much
April is when stale assumptions do the most damage. The page you last used in winter may still be useful, but the right move is to re-open it after 6 April and rebuild the baseline with the current-year figures rather than carrying forward an old scenario.
