Self Assessment Tax Return

Self Assessment Tax Returns

Your self assessment tax return can be daunting. Faced with a mountain of paperwork, or a bag of receipts, its difficult to summon the energy to begin. Added to that the worry of getting it wrong and it’s no wonder people running small businesses dread January.

I can take that mountain of paperwork, work out your tax liability and complete your self assessment tax return for you. I can also deal with HMRC directly on your behalf with your authorisation if required.

  • you’ve £2,500 or more of untaxed income, eg from renting out a property
  • you need to pay capital gains tax
  • you or your partner have income over £50,000 and one of you claimed child benefit
