Beyonce Knowles' father owes over $1.2 million in taxes.

Matthew Knowles - who managed his daughter during her rise to stardom as a teenager with Destiny's Child until 2011 - has been issued a lien by the US tax department, the Internal Revenue Service (IRS), to claim two sums of unpaid tax, TMZ reports.

Matthew, 61, reportedly owes $485,575.95 for 2010 and $728,004.89 for 2011, adding up to $1,213,580.84 for the final two years he was guiding Beyonce's career.

The music businessman previously admitted he found it ''incredibly painful'' to cut professional ties with his 31-year-old daughter.

He previously stated: ''It was hard for me to let her go - it was hard for both of us to let each other go. And let's be clear on that. She didn't let me go, we both let each other go. That's a big difference.

''This was not a normal ending of a business agreement. This was a dad and a daughter and it was incredibly painful and it had some difficulties.''

Despite Matthew claiming it was joint decision for him to stop being her manager, Beyonce - who has 16-month-old daughter Blue Ivy with her rapper husband Jay-Z - has admitted their split has taken a toll on their personal relationship.

In her recent HBO documentary 'Life Is But A Dream', she explained: ''It took a while for me and my dad to have an understanding. When I turned 18 and started handling my business more, he went into shock. And we had our issues. I'd say 'No' to something, and he'd book it anyway. Then I'd have to do it because I'd look bad [if I didn't] ... Every time he pushed me, I got stronger. I had to sacrifice my relationship with dad. I had to let go.''
