ASK TO PAY MORE INCOME TAX FOR 2008/09?

• I just received letter from income and revenue that i have underpaid tax for 2008/09 and ask to pay it back. I am nurse with three jobs. For that financial year; the main job my income was £32,871.34, taxed £5366.40(after personal allowance) and Final tax code was 603L. Second job, my income was £19,186.14, taxed £3837.20(no personal allowance) and final tax code was BR. Third job, my income was £8047.69, taxed £443.40 (with personal allowance) and final tax code was 603L. My dispute: The third job, I think the personal allowance was wrong because I have already received from main job. So, I used the basic rate (20%) to calculate the right amount was supposed to pay. It came £1609.54, therefore I underpaid by £1176.14. Their dispute: On the letter they sent to me, they add all the incomes and used basic rate (20%) up to £34,800 and the rest of income they used higher rate (40%). That is how they got I have underpaid by £6373 I read tax guide on internet about two jobs, it explained with example if you have two jobs and you are receiving £25,000 each still you will be able to pay basic rate although when you combine the two incomes, it exceeds basic rate limit (£34,800). According to my final tax codes (BR and 603L) are they right for me pay higher rate? And that guide line on the internet is wrong?

• Answer:

  Your PA was used against your first job, so all other income is taxed at 20/40%. Add up total income, deduct £6475 and tax balance to £34800 at 20%, the rest at 40%. Looks like you owe more than they're demanding!
