WASHINGTON (AP) — The Latest on the tax bill moving through Congress (all times local):

4:40 p.m.

Maine Republican Sen. Susan Collins says she’ll vote for her party’s tax bill this week.

The moderate’s support means all voting GOP senators are expected to back the measure. That’s enough to approve the $1.5 trillion package.

Collins cited provisions she says she helped win, including letting people deduct state and local income, sales and property taxes up to $10,000.

The House-passed version limited that to property tax deductions up to $10,000. Current law generally allows all local taxes to be deducted without limit.

Collins was among a handful of Republicans who helped derail her party’s effort this year to scuttle the “Obamacare” health law.

Republicans have a 52-48 Senate majority. Arizona GOP Sen. John McCain is battling brain cancer and is expected to miss the vote.

A nonpartisan group says the Republican tax bill would cut taxes on average for all income groups next year, with bigger reductions for upper-income people.

The analysts also say that by 2027, when most individual provisions expire, just over half would face tax increases. Those boosts would range from an average $90 for people making up to $28,000 yearly to $420 for those earning above $155,000.

The analysis was by the Tax Policy Center. It estimated that when the legislation takes effect next year, those earning below $25,000 would average a $60 tax cut. People earning above $149,000 would see $7,640 average reductions.

People making above $733,000 — the top 1 percent — would get an average $51,140 cut in 2027.

Congress is expected to approve the bill this week.
