Two months' wage taxed as one month
my employer did not pay my salary in January, but paid two salaries in February (for both January and February). As a result, they took a much higher tax (they taxed 43% on the whole amount, instead of 30%, for each month separately).
Who can advise what is the right tax to be paid in this case?
They do not want to adjust this difference. I would like to avoid having to wait till next year in April when this will tax difference will be returned.
Thank you in advance.
