Its unlikely with modern software that its taxed incorrectly, what you are seeing is that the software is allowing for you earn more now so its taxed with the formula that this is going to happen every month but when it doesn't it will tax you less and return some of what it took from this month. Its all worked out on making the sums right at the end of the year, if there is a lump payment or a low week for some reason it deducts or under deducts to compensate but it all washes out over the next payroll periods.
Narks me off at work when people give me grief about deductions, literally all we do is put in the tax code and how many hours worked and everything else is out of our hands. As long as you run updated payroll software (sage for me) there is nothing that can be done and how much or how little is taxed, its entirely out of the person running payrolls control.
