You do not need to love tax to avoid trouble with it. Half an hour once a year, ideally near the start of the tax year or just before the end, catches most problems while they are still easy to fix.
Check your code or withholding
Look at your most recent payslip and confirm your tax code, if your country uses one, or your withholding form details. Check your name, filing status, number of allowances or dependants, and any second job. If you have married, moved, had a child or changed jobs, update your details. A wrong setting means you either overpay all year or owe a lot at the end.
Run your numbers
Put your current pay into our calculator for your country or state and compare it with your payslip. If the figures are far apart, find the reason: a deduction you forgot, a different pension rate, or a code that needs updating. Our tip on why payslips differ from estimates lists the usual causes.
Use your allowances
Many countries give each person tax-free allowances, savings accounts or retirement contribution limits that reset every year and do not carry over. Check whether you have used yours. Putting extra into a tax-advantaged retirement account before the year ends is one of the few moves that can lower your tax and raise your savings at once.
Gather your records
Collect payslips, year-end statements, interest statements, receipts for deductible costs, and any letters from the tax office. Put them in one folder, on paper or on your computer. If you are self-employed, make sure your invoices and receipts are complete.
Look at what is coming
Think about changes ahead: a raise, a new job, a house purchase, a child, retirement. Each can change your tax position. Use the calculator to try the new income and see the effect before the change arrives.
Know when to ask for help
For anything complicated, such as several income sources, investments, overseas income or a business, a qualified tax adviser can often save more than they cost. Official tax-office websites also give free guidance. Our calculators give estimates for planning and are not tax advice.
