p45 question changing jobs.

problemnext

Im starting a new job on monday and currently working part time in another company. should i get a p45 from my current employer to give to the new job. if i dont will i get taxed heavily. i may still work part time at weekends for the current company. i.e working mon-fri with company a and most saturdays with company b. not sure what i need to do to avoid being taxed heavily.

If you're still working for the company a you won't get a P45 from them. If you're going to be working for the two companies at the same time, you just need to split your tax credits across both employments. As you're not sure how much work you'll be doing for company a, while working full time at company b, assuming you have been working full time at company a until now, you might as well just split the credits in half - at the end of the year, if you think you're owed anything back you can request a P21 balancing statement from Revenue, and they well refund any overpayments.

You don't need a P45, just update your details on-line with Revenue.

However, are you sure you can double job and not risk one of your employers being in breach of the Organisation of work act 1997
